    Objectives. We investigated Upstate New York school building conditions and examined the associations between school absenteeism and building condition problems. Methods. We merged data from the 2005 Building Condition Survey of Upstate New York schools with 2005 New York State Education Department student absenteeism data at the individual school level and evaluated associations between building conditions and absenteeism at or above the 90th percentile. Results. After adjustment for confounders, student absenteeism was associated with visible mold (odds ratio [OR] = 2.22; 95% confidence interval [CI] = 1.34, 3.68), humidity (OR = 3.07; 95% CI = 1.37, 6.89), poor ventilation (OR = 3.10; 95% CI = 1.79, 5.37), vermin (OR = 2.23; 95% CI = 1.32, 3.76), 6 or more individual building condition problems (OR = 2.97; 95% CI = 1.84, 4.79), and building system or structural problems related to these conditions. Schools in lower socioeconomic districts and schools attended by younger students showed the strongest associations between poor building conditions and absenteeism. Conclusions. We found associations between student absenteeism and adverse school building conditions. Future studies should confirm these findings and prioritize strategies for school condition improvements.

    The recently-built school buildings have adopted novel heat recovery ventilator and air conditioning system. Heat recovery efficiency of the heat recovery facility and energy conservation ratio of the air conditioning unit were analytically modeled, taking the ventilation networks into account. Following that, school classroom displacement ventilation and its thermal stratification and indoor air quality indicated by the CO 2 concentration have been numerically modeled concerning the effects of delivering ventilation flow rate and supplying air temperature. Numerical results indicate that the promotion of mechanical ventilation rate can simultaneously boost the dilution of indoor air pollutants and the non-uniformity of indoor thermal and pollutant distributions. Subsequent energy performance analysis demonstrates that classroom energy demands for ventilation and cooling could be reduced with the promotion of heat recovery efficiency of the ventilation facility, and the energy conservation ratio of the air conditioning unit decreases with the increasing temperatures of supplying air. Fitting correlations of heat recovery ventilation and cooling energy conservation have been presented. - Highlights: • Low energy school buildings and classroom environment. • Heat recovery facility operating with an air conditioning unit. • Displacement ventilation influenced by the heat recovery efficiency. • Energy conservation of cooling and ventilation through heat recovery. • Enhancement of classroom environment with reduction of school building energy

    2014-11-01

    Full Text Available Much of the focus in the literature in raising student achievement has included parental involvement, principal leadership, quality of instruction, students’ socioeconomic status, curriculum, and use of technology. Limited empirical research relates the condition of the school building as a variable that affects student achievement. Furthermore, there is no research that has examined the impact of building codes on achievement outcomes in the state of Florida. This research determined whether academic achievement of 4th-, 8th-, 9th-, and 10th-grade students as measured by the mathematics and reading subtests of the Florida Comprehensive Achievement Test (FCAT increased in new school buildings compliant to the 2000 Florida State Requirements for Educational Facilities. A causal-comparative design determined whether the independent variables, old and new school building influenced student achievement as measured by students’ FCAT mathematics and reading subtest scores. The control group was two cohorts of 4th-, 8th-, 9th-, and 10th-grade students who attended school in old buildings. The experimental group was two cohorts of 4th-, 8th-, 9th-, and 10th-grade students who attended school in new buildings. Transition from an old school into a new school was the treatment. Two hypotheses were formulated for testing and the research question for the inquiry was whether the percentage of students passing the FCAT mathematics and reading subtests increases after transitioning from an old school building into a new 2000 UBC (Uniform Building Code compliant facility.

    Building Information Modelling is a methodology, which is able to take into account many data, both geometrical and non-geometrical, in order to evaluate at the actual condition of the asset. The project has the scope of evaluating the conditions of different school buildings, in order to develop a way to choose the best-tailored management solution to the owner. A further step is the management and planning of design solutions during the life cycle customized on monitored buildings' conditions. The research work focuses on providing a support decisions concerning the gap between the present building state laws and the current state of the existing buildings. The process will be developed in an expanded BIM environment, using sensors, which will give back the state of the consistency of the actual conditions to enable the buildings to adapt themselves in the best way into their specific constraints and boundaries. The results of the study are (i) a complete workflow to make decision and the possibility to shape the decision process on an objective through a scientific approach, (ii) evaluate the current state of the asset and (iii) manage maintenance in the lifespan. Further development will take in consideration all the aspects related to management of big data environment generated by a smart buildings system.

    Full Text Available The aim of the study was to determine the species composition of fungi occurring on wall surfaces and in the air in school buildings. Fungi isolated from the air using the sedimentation method and from the walls using the surface swab technique constituted the study material. Types of finish materials on wall surfaces were identified and used in the analysis. Samples were collected in selected areas in two schools: classrooms, corridors, men's toilets and women's toilets, cloakrooms, sports changing rooms and shower. Examinations were conducted in May 2005 after the heating season was over. Fungi were incubated on Czapek-Dox medium at three parallel temperatures: 25, 37 and 40°C, for at least three weeks. A total of 379 isolates of fungi belonging to 32 genera of moulds, yeasts and yeast-like fungi were obtained from 321 samples in the school environment. The following genera were isolated most frequently: Aspergillus, Penicillium and Cladosporium. Of the 72 determined species, Cladosporium herbarum, Aspergillus fumigatus and Penicillium chrysogenum occurred most frequently in the school buildings. Wall surfaces were characterised by an increased prevalence of mycobiota in comparison with the air in the buildings, with a slightly greater species diversity. A certain species specificity for rough and smooth wall surfaces was demonstrated. Fungi of the genera Cladosporium and Emericella with large spores adhered better to smooth surfaces while those of the genus Aspergillus with smaller conidia adhered better to rough surfaces. The application of three incubation temperatures helped provide a fuller picture of the mycobiota in the school environment.

    Full Text Available Sustainable construction is important for the continuation of life in a healthy world for futuregenerations; many issues affecting the quality of life such as effective use of resources, take advantage ofrenewable energy, the choice of recyclable materials that do not harm the environment and waterconservation are considered in the context of sustainable design. Implementations carried out in thisframework are regarded as valuable due to providing the consciousness of sustainability to the society.Creating the awareness of sustainability is given a great importance by educators; thus, “education forsustainability” are included from the preschool program so that children can learn the gainings of suchperspective in their early ages. In support of this concept, it is believed that education structures should bea laboratory where children can practice theoretical knowledge learned at school. In that respect, studiesneed to be considered in the context of sustainable construction are studied in this research. In the study,after a description of the importance of sustainable design as a learning mean, significant subjects such asusing natural light, heating, cooling and air-conditioning methods, wind energy, water protection andmaterial selection are analyzed in terms of designing sustainable schools. It is criticized worldwide thatstructures ground on sustainable design principles are relatively few in numbers. Despite, there is anincreasing interest to the subject in Turkey later years; a lot more steps are required in terms ofimplementation and research of the issue. Thus, the purpose of the study is to provide a supplementaryreference for school designs.

    1982-01-01

    Purpose: To decrease the opening areas of pipe lines for an air conditioning device at the portions passing through the shielding walls of a reactor building for a FBR type reactor, as well as reduce the size of the building. Constitution: Airs in the building for containing reactor are liquefied in an air liquefying mechanism. The liquefied airs are sent by way of pipe lines to each of evaporators, wherein each of the chambers are cooled because of latent heat of evaporation and evaporated airs are released to each of the chambers. The airs released to each of the chambers are collected into an exhaust chamber and sent by way of a duct to the air liquefying mechanism and liquefied again. Since the volume of the liquefied airs may be smaller than the amount conventionally required for usual cooled airs, the pipe lines passing through the shielding walls of the building can be of smaller diameter. This can decrease the opening areas of the pipe lines at the portions passing through the walls of the shieldings and, since the opening areas are smaller, the structure of the radiation shieldings can be simplified in these portions. Further, since the space of the pipe lines in the building is reduced extremely, the size of the building can be reduced. (Moriyama, K.)

    European regulations set the condition of Zero Energy Buildings for new buildings since 2020, with an intermediate milestone in 2018 for public buildings, in order to control greenhouse gases emissions control and climate change mitigation. Given that main fraction of energy consumption in buildings operation is due to HVAC systems, advances in its design and operation conditions are required. One key element for energy demand control is passive design of buildings. On this purpose, different recent studies and publications analyse natural ventilation systems potential to provide indoor air quality and comfort conditions minimizing electric power consumption. In these passive systems are of special relevance their capacities as passive cooling systems as well as air renovation systems, especially in high-density occupied spaces. With adequate designs, in warm/mild climates natural ventilation systems can be used along the whole year, maintaining indoor air quality and comfort conditions with small support of other heating/cooling systems. In this paper is analysed the state of the art of natural ventilation systems applied to high density occupied spaces with special focus on school buildings. The paper shows the potential and applicability of these systems for energy savings and discusses main criteria for their adequate integration in school building designs.

    2018-06-01

    Full Text Available Decades ago, the only requirement to construct a building was to give men the right conditions for the execution of their work or leisure activities. With the development of knowledge about the internal and external environments of buildings, other requirements have been added such as the issue of user comfort. New construction techniques have been incorporated and new products have been created to improve internal environment comfort. This research addressed the importance of using indicators related to environmental comfort in sustainability assessment tools applied to school buildings. It also considered the importance of environmental issues for the good performance of human beings, and the harmonious coexistence of the comfort indicators indoor air quality, thermal comfort, visual comfort, acoustic comfort and ergonomic comfort based on data gathered in research carried out with users of high schools (only students. This research was carried out in two different cities of different countries, Guimarães (Portugal and Juiz de Fora (Brazil, that have similar characteristics of teaching standards and climate conditions (temperature and air humidity. In this study, interviews were made through questionnaires and, later, the information collected was analyzed. This study demonstrates the need to include an ergonomic indicator for school buildings in sustainability assessment tools.

  15. School Buildings for the 21st Century Some Features of New School Buildings in Iceland

    2011-01-01

    Full Text Available The aim of this study is to identify features of change in the recent design of school buildings in Iceland, and how they might affect teaching practices. Environmental and architectonic features characterising school buildings designed and built at the beginning of the 21st century are examined in light of challenges involving architecture, educational ideology, school policy and digital technology. The sample for the study consists of 20 schools located in four municipalities. Four of the school buildings were developed and built in this century, while the other 16 were designed in the 20th century. The design of all of the buildings was explored and reviewed by a multidisciplinary team. Data was collected by observations and photography at each school site, as well as by reviewing technical documents. The relationship between school design and school practices was studied through a questionnaire survey among all teachers, in order to find out whether teachers working in new environments differ from teachers in more traditional classroom settings. The results indicate a clear shift in the design of educational buildings. Flexibility, flow, openness and teamwork seem to guide recent school design. Clusters of classrooms or open spaces, transparent or movable boundaries, as well as shared spaces allowing for manifold interactions in flexible groups seem to be replacing traditional classrooms along confining corridors. Teachers working in open classroom environments collaborate more often than their counterparts. Teaching practices are also characterised by more opportunities for pupils to choose between tasks and enjoy more variation regarding group division and workspace arrangements.

    Atria have become popular additions to many building types in recent years. There is a common misconception that they will automatically result in lower energy consumption, but this is not necessarily the case. Only when designed and used in an appropriate way will atria contribute to energy conservation. In this paper the performance of two school buildings, one incorporating a heat atrium, the other an unheated atrium, was studied. Comparisons between their performance were made with respect to thermal comfort, heating costs, overheating and daylighting. While heating the atrium incurred a cost penalty, it resulted in comfortable conditions in the space for a greater proportion of the time in winter, and consequently created a more useful space. In summer months overheating was likely unless an area of opening vents the equivalent of 10% or more of the floor area is provided in the atrium roof. (author)

    The paper is focused on the building ad-hoc GSM network based on open source software and low-cost hardware. The created Base Transmission Station can be deployed and put into operation in a few minutes in a required area to ensure private communication between connected GSM mobile terminals. The convergence between BTS station and the other networks is possible through IP network. The paper tries to define connection parameters to provide sufficient quality of voice service between the GSM network and IP Multimedia Subsystem. The paper brings practical results of voice call quality measurement between users inside BTS station mobile network and users inside IP Multimedia Subsystem network. The calls are simulated by low-cost embedded solution for speech quality measurement in GSM network. This tool is under development of our laboratory and allows automatic speech quality measurement of any GSM or UMTS mobile network. The Perceptual Evaluation of Speech Quality method is used to get final comparable results. The communication between BTS station and connected networks has to be secured against the interception from the third party. The influence of the securing method for quality of service is presented in detail. Paper, apart from the quality of service measurement section, describes technical requirements for successful interconnection between BTS and IMS networks. The authentication, authorization and accounting methods in roaming between BTS and IMS system are presented too.

    Highlights: • Electricity and heating energy consumptions of six school buildings were compared. • Complex multivariate data was analysed using modern computational methods. • Variation in electricity consumption cost is considerably low between study schools. • District heating variation is very slight in two new study schools. • District heating cost describes energy efficiency and state of building automation. - Abstract: Even though industry consumes nearly half of total energy production, the relative share of total energy consumption related to heating and operating buildings is growing constantly. The motivation for this study was to reveal the differences in electricity use and district heating consumption in school buildings of various ages during the working day and also during the night when human-based consumption is low. The overall aim of this study is to compare the energy (electricity and heating) consumption of six school buildings in Kuopio, Eastern Finland. The selected school buildings were built in different decades, and their ventilation and building automation systems are also inconsistent. The hourly energy consumption data was received from Kuopion Energia, the local energy supply company. In this paper, the results of data analysis on the energy consumption in these school buildings are presented. Preliminary results show that, generally speaking, new school buildings are more energy-efficient than older ones. However, concerning energy efficiency, two very new schools were exceptional because ventilation was on day and night in order to dry the building materials in the constructions. The novelty of this study is that it makes use of hourly smart metering consumption data on electricity and district heating, using modern computational methods to analyse complex multivariate data in order to increase knowledge of the buildings’ consumption profiles and energy efficiency.

  4. Infrared survey of 50 buildings constructed during 100 years: thermal performances and damage conditions

    Science.gov (United States)

    Ljungberg, Sven-Ake

    1995-03-01

    Different building constructions and craftsmanship give rise to different thermal performance and damage conditions. The building stock of most industrial countries consists of buildings of various age, and constructions, from old historic buildings with heavy stone or wooden construction, to new buildings with heavy or light concrete construction, or modern steel or wooden construction. In this paper the result from a detailed infrared survey of 50 buildings from six Swedish military camps is presented. The presentation is limited to a comparison of thermal performance and damage conditions of buildings of various ages, functions, and constructions, of a building period of more than 100 years. The result is expected to be relevant even to civilian buildings. Infrared surveys were performed during 1992-1993, with airborne, and mobile short- and longwave infrared systems, out- and indoor thermography. Interpretation and analysis of infrared data was performed with interactive image and analyzing systems. Field inspections were carried out with fiber optics system, and by ocular inspections. Air-exchange rate was measured in order to quantify air leakages through the building envelope, indicated in thermograms. The objects studied were single-family houses, barracks, office-, service-, school- and exercise buildings, military hotels and restaurants, aircraft hangars, and ship factory buildings. The main conclusions from this study are that most buildings from 1880 - 1940 have a solid construction with a high quality of craftsmanship, relatively good thermal performance, due to extremely thick walls, and adding insulation at the attic floor. From about 1940 - 1960 the quality of construction, thermal performance and craftsmanship seem to vary a lot. Buildings constructed during the period of 1960 - 1990 have in general the best thermal performance due to a better insulation capacity, however, also one finds here the greatest variety of problems.

    Full Text Available It is possible to achive the bio-climatical comfort is buildings by setting the indoor temperature at certain level at which the people feels himself comfortable. The indoor temperature changing with the summer-winter climate conditions and with the building materials should always be around desirable level. Therefore, the variation of indoor temperature depending on the natural and artifical cooling and heating of building materials, within the range of design, is becoming so important. For this reason, in this investigation, the variation of indoor temperature has been analysed considering the variation of heat gain by convection, radiation and infiltration, the heat capacity of materials used in building including the outdoor and the temperature of outer ambient. In addition to this, the variation of indoor temperature with time has been computed under the condition that whether the cooling source exist or not. For this purpose, the heat gains, the indoor and outer temperature, the capacity of cooling system and solar radiation have been expressed analyticaly by transforming them into Fourier series.

  10. Cost and effectiveness of radon-resistant features in new school buildings

    International Nuclear Information System (INIS)

    Craig, A.B.; Leovic, K.W.; Saum, D.W.

    1991-01-01

    Recent concerns over elevated levels of radon in existing buildings have prompted the design and construction of a number of school buildings that either are radon resistant or incorporate features that facilitate post-construction mitigation if needed. This paper describes initial results of a study of several schools with radon-resistant features that were recently constructed in the northeastern US. These designs are generally based on experience with radon mitigation in existing houses and schools and radon-resistant new house construction. The study was limited to slab-on-grade schools, where the most common radon-resistant school design is active subslab depressurization (ASD). The additional construction costs for eight schools built with ASD ranged from $3 to $11 per square meter of slab area. The radon contractors who designed these systems have tended to overdesign the radon-reduction systems in the absence of specific written guidance to follow to lessen potential liability in the event of system failure. Design features include detailed sealing of all stab cracks, multiple exhaust stacks, and extensive subslab piping. Recent Environmental Protection Agency (EPA) research on radon mitigation suggests that simpler ASD systems may provide sufficient radon resistance in new large buildings at lower costs. Components of a specification for radon-resistant school construction are discussed, based on comments from radon system designers. Another school being studied was built with a heating, ventilating, and air-conditioning (HVAC) pressurization radon control system, and considerations for this type of system are examined

  11. Costs of radon diagnostics and mitigation in school building

    Leovic, K.W.; Rector, H.; Nagda, N.

    1992-01-01

    To determine the costs of radon diagnostics and active soil depressurization (ASD) system installation in schools, seven radon mitigators with extensive experience in school buildings were surveyed. The cost data were determined by providing the mitigators with two scenarios of open-quotes typicalclose quotes school buildings with elevated radon levels. The questionnaire in schools: (1) Review Construction Plans, (2) Conduct Diagnostic Measurements, (3) Design Mitigation System, (4) Purchase ASD Material, and (5) Install and Checkout ASD System. Based on the results of this survey, it is estimated that the average cost of ASD diagnostics and mitigation in a typical school would be roughly $0.50 per ft 2 . However, these costs would be higher in schools with extensive subslab walls, very poor PFE, and lower in simple schools with very good PFE and no subslab barriers to communication. The variations in costs provided by the mitigators are primarily due to the influences of (1) experience and practices of the mitigation companies, (2) ASD system requirements as perceived by the respondents, and (3) the degree of involvement by the school system in the process

  20. The radon problem in schools and public buildings in Belgium

    International Nuclear Information System (INIS)

    Poffijn, A.; Uyttenhove, J.; Tondeur, F.

    1992-01-01

    Owing to differences in geology, radon in Belgium is recognised to be a more serious problem in the southern part of the country than in the northern part. From national and regional surveys, it became clear that in the province of Luxembourg indoor radon concentrations exceeding the European reference level of 400 Bq.m -3 frequently occur. As many people (children as well as adults) spend an important part of the day indoors at school or at work, it was decided by the local authorities to conduct a more systematic survey. In all schools and public buildings, measurements with integrating etched track devices have been performed. The results of these campaigns are discussed and a limiting scheme for radon in schools and public buildings, based mainly upon the existing Belgian regulations for protecting against ionising radiation is presented.

  1. The effects of HVAC system design and operation on radon entry into school buildings

    International Nuclear Information System (INIS)

    Turner, W.A.; Leovic, K.W.; Craig, A.B.

    1990-01-01

    Heating, ventilating, and air conditioning (HVAC) systems in schools vary considerably and tend to have a greater impact on pressure differentials--and consequently radon levels--than do heating and air-conditioning systems in houses. If the HVAC system induces a negative pressure relative to the subslab area, radon can be pulled into the building. If the HVAC system pressurizes the building, it can prevent radon entry as long as the fan is running. However, school HVAC systems are normally set back or turned off on evenings and weekends and, even if the HVAC system pressurizes the school during operation, indoor radon levels may build up during setback periods. In this paper many of the historical methods utilized to deliver ventilation air (outdoor air) over the past 40 years are summarized. In addition, for each type of system presented, the possible impact the ventilation system might be expected to have (positive or negative) on the pressure of the building envelope (and subsequent radon levels in the building) is discussed

    This paper presents results to thermal comfort and environment quality questions in 21 school building rooms. Results show that about 80% of the occupants expressed satisfaction with their thermal comfort in only 11% of the buildings surveyed. Air quality scores were somewhat higher, with 26% of buildings having 80% or occupant satisfaction. With respect to thermal comfort and air quality performance goals set out by standards, most buildings appear to be falling far short. Occupant surveys offer a means to systematically measure this performance, and also to provide diagnostic information for building designers and operators. The odours from building materials as well as human odours were studied by field measurement. The odour intensity and indoor air acceptability were assessed by a sensory panel. The concentrations of total volatile organic compounds and carbon dioxide were measured. The odours from occupancy and building materials were studied under different air change rate. The case study of indoor air acceptability concerning to indoor odours and its effect on perceived air quality are also presented in this paper.

    The paper summarizes the reconstruction of the historical building erected in the 14th century, during the times of the residence of Grand Master of the Teutonic Order Winrich von Kniprode, currently referred to as the Latin School. It characterizes the location of the Latin School in the urban conservation area of the town of Malbork. The building is situated in the stretch of the buttressed brick escarpment on the Nogat River in the line of the historic defensive walls of Malbork. The paper also outlines the history of this building, constructed and managed by the municipal authorities of Malbork, which for a long time was a seat of a Patronage of Saint George and the Merchant Guild, and next, from the 16th century until 1864, the building housed a school where basic Latin was taught. Next, the situation of this historical monument in the 20th century is discussed. In the next part of the paper, the geological conditions of the site where the building was erected are discussed. The conducted archeological and architectural exploratory research related to the historical building with a particular emphasis on historic preservation and restoration works focusing on the building and its surroundings is presented and analyzed. Currently carried out design, construction and adaptation works allowing new functions to be embedded into this building are also discussed. The paper shows the benefits due to the realization of the reconstruction program of the degraded building of the Latin school in the historic quarter of the town. These activities are aimed at the conversion of the currently derelict building by means of embedding new functions into it. There are being designed, among others, an interactive educational center modern library, astronomical observatory, craft museum and multifunctional hall, allowing proper conditions to be created for the development of educational, artistic and tourism related activities in the reconstructed building.

    This paper concerns an applied research aimed at applying the concept of usability, as derived form the standard ISO 9241/11, in the filed of building design, namely primary schools. Starting from the concept that space characteristics play a very relevant role in learning performances, the study presented here developed an original methodology for the assessment of effectiveness, efficiency and satisfaction of buildings hosting primary schools, in order to create a school environment better supporting users in their tasks. Research core is the framework of usability requirements and their related markers, indicators and technical specification that has been formulated in order to check compliance of urban area, building, rooms and architectural details with users needs. Therefore, a detailed task analysis of pupils and teacher tasks has been carried out and two questionnaires addressed to a significant users panel have been formulated for satisfaction survey. Lastly, a matrix for an overall reading of gathered data has been set-up and criteria for usability assessment based on that data has been defined. The whole study has been developed within the case study of a primary school in the Naples city centre, whose contents and results are discussed.

    The purpose of Equipment Qualification (EQ) in nuclear power plants is to ensure the capability of safety related equipment to perform its function on demand under postulated service conditions, including harsh accident environment (e.g. Loss of Coolant Accident - LOCA, High Energy Line Break - HELB). The determination of the EQ conditions and zones is one of the basic steps in the frame of the overall EQ project. The EQ parameters (temperature, pressure, relative humidity, chemical spray, submergence, radiation) should be defined for all locations of the plant containing equipment important to safety. This paper presents the calculation of thermohydraulic environmental parameters (pressure and temperature) inside Intermediate Building (IB) of Krsko NPP after the postulated HELB. The RELAP5/mod2 computer code was used for the determination of HELB mass and energy release and computer code GOTHIC was used to calculate pressure and temperature profiles inside NPP Krsko IB.

    The Building Technologies Office (BTO), within the U.S. Department of Energy’s (DOE) Office of Energy Efficiency and Renewable Energy, works with researchers and industry to develop and deploy technologies that can substantially reduce energy consumption and greenhouse gas (GHG) emissions in residential and commercial buildings. Air conditioning (A/C) systems in buildings contribute to GHG emissions both directly through refrigerant emissions, as well as indirectly through fossil fuel combustion for power generation. BTO promotes pre-competitive research and development (R&D) on next-generation HVAC technologies that support the phase down of hydrofluorocarbon (HFC) production and consumption, as well as cost-effective energy efficiency improvements. Over the past several decades, product costs and lifecycle cooling costs have declined substantially in many global markets due to improved, higher-volume manufacturing and higher energy efficiency driven by R&D investments and efficiency policies including minimum efficiency standards and labeling programs.1 This report characterizes the current landscape and trends in the global A/C market, including discussion of both direct and indirect climate impacts, and potential global warming impacts from growing global A/C usage. The report also documents solutions that can help achieve international goals for energy efficiency and GHG emissions reductions. The solutions include pathways related to low-global warming potential2 (GWP) refrigerants, energy efficiency innovations, long-term R&D initiatives, and regulatory actions. DOE provides, with this report, a fact-based vision for the future of A/C use around the world. DOE intends for this vision to reflect a broad and balanced aggregation of perspectives. DOE brings together this content in an effort to support dialogue within the international community and help keep key facts and objectives at the forefront among the many important discussions.

    The Cincinnati School Health Demonstration Project was a 3-year collaboration that evaluated school-linked health services in 6 urban elementary (kindergarten to eighth grade) schools. Partners from the Cincinnati Health Department, Cincinnati Public Schools, Cincinnati Children's Hospital Medical Center, and The Health Foundation of Greater Cincinnati wanted to determine if levels of school-linked care made a difference in student quality of life, school connectedness, attendance, emergency department use, and volume of referrals to health care specialists. School nurses, principals and school staff, parents and students, upper-level managers, and health service researchers worked together over a 2.5-year period to learn about and use new technology to collect information on student health, well-being, and outcome measures. Varying levels of school health care intervention models were instituted and evaluated. A standard model of care was compared with 2 models of enhanced care and service. The information collected from students, parents, nurses, and the school system provided a rich database on the health of urban children. School facilities, staffing, and computer technology, relationship building among stakeholders, extensive communication, and high student mobility were factors that influenced success and findings of the project. Funding for district-wide computerization and addition of school health staff was not secured by the end of the demonstration project; however, relationships among the partners endured and paved the way for future collaborations designed to better serve urban school children in Cincinnati.

    1988-01-01

    Although the radiological conditions following the TMI-2 accident were extraordinary, those that had a potential impact on personnel were largely confined to the Auxiliary and Fuel Handling Building. The most significant pathway was the Letdown and Make-Up and Purification System. Dose rates in some locations in the Aux/Fuel Handling Buildings were in excess of 3 mSv/s (1000 R/h) during the first few days following the accident. They decreased after three to four days and stabilized after about one week. Airborne radioactivity levels were initially due to the release of noble gases, and subsequently due to resuspension of surface contamination. During the first month, the mixture of fission products in the reactor coolant change from one of largely cesium to where the strontium and cesium were about equal in radiological importance. This created some very high beta radiation levels. The significant strontium levels caused the contamination control limit to be reduced to one-half of the pre-accident limit. 5 refs., 6 figs

    School facility conditions, environment, and perceptions of safety and learning have been investigated for their impact on child development. However, it is important to consider how the environment separately influences academic performance and attendance after controlling for school and community factors. Using results from the Maryland School Assessment, we considered outcomes of school-level proficiency in reading and math plus attendance and chronic absences, defined as missing 20 or more days, for grades 3-5 and 6-8 at 158 urban schools. Characteristics of the environment included school facility conditions, density of nearby roads, and an index industrial air pollution. Perceptions of school safety, learning, and institutional environment were acquired from a School Climate Survey. Also considered were neighborhood factors at the community statistical area, including demographics, crime, and poverty based on school location. Poisson regression adjusted for over-dispersion was used to model academic achievement and multiple linear models were used for attendance. Each 10-unit change in facility condition index, denoting worse quality buildings, was associated with a decrease in reading (1.0% (95% CI: 0.1-1.9%) and math scores (0.21% (95% CI: 0.20-0.40), while chronic absences increased by 0.75% (95% CI: 0.30-1.39). Each log increase the EPA's Risk Screening Environmental Indicator (RSEI) value for industrial hazards, resulted in a marginally significant trend of increasing absenteeism (p < 0.06), but no association was observed with academic achievement. All results were robust to school-level measures of racial composition, free and reduced meals eligibility, and community poverty and crime. These findings provide empirical evidence for the importance of the community and school environment, including building conditions and neighborhood toxic substance risk, on academic achievement and attendance.

    Full Text Available This paper studies the way in which headmasters and class masters perceive and estimate the factors, obstacles and incentives to building up a partnership between school and parents. The sample consists of 60 headmasters and 305 class masters from 60 schools (37 urban and 23 rural in Serbia. Headmasters and teachers filled in separate, but parallel questionnaires (modified only in the segment of different roles that were created for the purposes of research. Questionnaire items inquire about the factors contributing to the inclusion of parents, the obstacles in developing the cooperation between parents and school and the peculiarities of school environment that can contribute to the development of that cooperation, as well as about the peculiarities of the communication with parents. Research findings indicate that headmasters and teachers assess the importance of different components in the field of cooperation with parents in a similar, but not identical way. Most similarities are found in the perception of obstacles for establishing cooperation (the problems of coordinating time periods for meetings, previous bad experiences of parents regarding cooperation. The majority of differences lie in perceiving the importance of cooperation factors (headmasters emphasise the "parent factor", while teachers do so both for the "parent factor" and "child factor", as well as in perceiving the necessary incentives for the improvement of cooperation between school and parents (headmasters emphasise the spatial-temporal organization components, and teachers do so for spatial components and personal initiatives. In the assessments of both the headmasters and teachers we obtained differences marked by gender, the longitude of years of service, size of the settlement where the school is located (town-village. The general conclusion indicates that the topic of cooperation between school and parents is highly and in many ways context sensitive, and that the

    1991-01-01

    The paper discusses radon prevention in the design and construction of schools and other large buildings. The U.S. EPA's Office of Research and Development (ORD) has started incorporating radon control measures into the design and construction of new schools and other large buildings. The goal of the new designs is twofold: (1) to prevent elevated radon levels in the completed building, and (2) to provide the protection at a fraction of the cost of retrofit systems. ORD's Air and Energy Engineering Research Laboratory (AEERL) has conducted the research necessary to develop viable designs. The Indoor Radon Abatement Act of 1988 set a national long-term goal for indoor radon of 0.5 picocurie per liter (pCi/L)--the same as that typically found in outdoor air. The EPA currently recommends that homeowners take action to reduce radon levels to below 4 pCi/L. To achieve the national goal set in the 1988 Act for new construction in radon-prone areas, AEERL research is using a combination of active subslab depressurization (ASD) and operation of the heating, ventilation, and air-conditioning (HVAC) system to pressurize buildings. These measures are described briefly, along with a case history of one building

Garments industries are one of the top most items of exported items. A huge number of populations are working in garments industries. But these factories are not well designed in sense of the thermal environment. Workers experiences sickness related to indoor environment. The productions of these factories are affected due to employees’ health condition. The research is done in two different methods. One is empirical data collection using thermal data loggers and the other is questionnaire survey on the spots for three factory buildings. The field study was conducted in four different months of the same year during winter and summer period. Expected findings of this research are that the indoor environment is not comfortable for works at day time during summer season. This research will help the factory workers in providing a comfortable thermal environment and also help the employers or factory owners to increase their production margin.

    Dalvi, Ambalika Rajendra

    Improving the conditions of schools in many parts of the world is gradually acquiring importance. The Green School movement is an integral part of this effort since it aims at improving indoor environmental conditions. This would in turn, enhance student- learning while minimizing adverse environmental impact through energy efficiency of comfort-related HVAC and lighting systems. This research, which is a part of a larger research project, aims at evaluating different school building designs in Albania in terms of energy use and indoor thermal comfort, and identify energy efficient options of existing schools. We start by identifying three different climate zones in Albania; Coastal (Durres), Hill/Pre-mountainous (Tirana), mountainous (Korca). Next, two prototypical school building designs are identified from the existing stock. Numerous scenarios are then identified for analysis which consists of combinations of climate zone, building type, building orientation, building upgrade levels, presence of renewable energy systems (solar photovoltaic and solar water heater). The existing building layouts, initially outlined in CAD software and then imported into a detailed building energy software program (eQuest) to perform annual simulations for all scenarios. The research also predicted indoor thermal comfort conditions of the various scenarios on the premise that windows could be opened to provide natural ventilation cooling when appropriate. This study also estimated the energy generated from solar photovoltaic systems and solar water heater systems when placed on the available roof area to determine the extent to which they are able to meet the required electric loads (plug and lights) and building heating loads respectively. The results showed that there is adequate indoor comfort without the need for mechanical cooling for the three climate zones, and that only heating is needed during the winter months.

    Much attention has been paid to hospitals environments since modern pandemics have emerged. The building sector is considered to be the largest world energy consumer, so many global organizations are attempting to create a sustainable environment in building construction by reducing energy consumption. Therefore, maintaining high standards of hygiene while reducing energy consumption has become a major task for hospitals. This study develops a decision model based on genetic algorithms and A* graph search algorithms to evaluate existing hospital environmental conditions and to recommend an optimal scheme of sustainable renovation strategies, considering trade-offs among minimal renovation cost, maximum quality improvement, and low environmental impact. Reusing vacant buildings is a global and sustainable trend. In Taiwan, for example, more and more school space will be unoccupied due to a rapidly declining birth rate. Integrating medical care with local community elder-care efforts becomes important because of the aging population. This research introduces a model that converts a simulated vacant school building into a community public hospital renovation project in order to validate the solutions made by hospital managers and suggested by the system. The result reveals that the system performs well and its solutions are more successful than the actions undertaken by decision-makers. This system can improve traditional hospital building condition assessment while making it more effective and efficient. PMID:27347986

    2015-01-01

    For a stand-alone retail building, a primary school, and a secondary school in each of the 16 California climate zones, the EnergyPlus building energy simulation model was used to estimate how minimum mechanical ventilation rates (VRs) affect energy use and indoor air concentrations of an indoor-generated contaminant. The modeling indicates large changes in heating energy use, but only moderate changes in total building energy use, as minimum VRs in the retail building are changed. For example, predicted state-wide heating energy consumption in the retail building decreases by more than 50% and total building energy consumption decreases by approximately 10% as the minimum VR decreases from the Title 24 requirement to no mechanical ventilation. The primary and secondary schools have notably higher internal heat gains than in the retail building models, resulting in significantly reduced demand for heating. The school heating energy use was correspondingly less sensitive to changes in the minimum VR. The modeling indicates that minimum VRs influence HVAC energy and total energy use in schools by only a few percent. For both the retail building and the school buildings, minimum VRs substantially affected the predicted annual-average indoor concentrations of an indoor generated contaminant, with larger effects in schools. The shape of the curves relating contaminant concentrations with VRs illustrate the importance of avoiding particularly low VRs.

The authors investigated several variants of single-layer building envelopes, used frequently in building practice, with different density and coefficients of building materials thermal conductivity. For each variant of a building envelope heat leakage and time spent on heating were calculated. Heating time was calculated by both exact and approximate analytical method. Then the researchers draw a graphic dependence of energy consumption on the density of the material taking this computational data as a basis. Further analysis showed that building envelopes made of lightweight aggregate concrete and porous concrete were the most energy efficient.This paper focuses on energy consumption for heating single layer building envelopes, used in conditions of intermittent heating in different physical and mechanical and thermophysical parameters of construction materials.

    1994-01-01

    As part of a continuing radon in schools technology development effort, EPA's School Evaluation Team has performed radon mitigation in schools by the method of ventilation/pressurisation control technology. Ventilation rates were increased, at a minimum, to meet the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) standard, Ventilation for Acceptable Indoor Air Quality (ASHRAE 62-1989). This paper presents the results and the preliminary evaluations which led to the team's decision to implement this technology. Factors considered include energy penalties, comfort, indoor air quality (IAQ), building shell tightness, and equipment costs. Cost benefit of heat recovery ventilation was also considered. Earlier results of the SEP team's efforts have indicated a severe ventilation problem within the schools of the United States. Two case studies are presented where HVAC technology was implemented for controlling radon concentrations. One involved the installation of a heat recovery ventilator to depressurise a crawl space and provide ventilation to the classrooms which previously had no mechanical ventilation. The other involved the restoration of a variable air volume system in a two-storey building. The HVAC system's controls were restored and modified to provide a constant building pressure differential to control the entry of radon. Pre-mitigation and post-mitigation indoor air pollutant measurements were taken, including radon, carbon dioxide (CO 2 ), particulates, and bio-aerosols. Long-term monitoring of radon, CO 2 , building pressure differentials, and indoor/outdoor temperature and relative humidity is presented. (author)

  14. Energy policy for integrating the building environmental performance model of an air conditioned building in a subtropical climate

    International Nuclear Information System (INIS)

    Mui, K.W.

    2006-01-01

    For an air conditioned building, the major electricity consumption is by the heating, and air conditioning (HVAC) system. As energy saving strategies may be in conflict with the criteria of indoor air quality and thermal comfort, a concept of the building environmental performance model (BEPM) has been developed to optimize energy consumption in HVAC systems without any deterioration of the indoor air quality and thermal comfort. The BEPM is divided into two main modules: the adaptive comfort temperature (ACT) module and the new demand control ventilation (nDCV) module. This study aims to enhance and prompt the conventional operation of the air side systems by incorporating temperature reset with the adaptive comfort temperature control and the new demand control ventilation system in high rise buildings in Hong Kong. A new example weather year (1991) was established as a reference to compute the energy use of HVAC systems in buildings in order to obtain more representative data for predicting annual energy consumption. A survey of 165 Hong Kong office buildings was conducted and it provided valuable information on the existing HVAC design values in different grades of private commercial buildings in Hong Kong. It was found that the actual measured values of indoor temperature were lower than the design ones. Furthermore, with the new example weather year and the integration of the BEPM into Grade A private office buildings in Hong Kong, the total energy saving of the air conditioning systems was calculated (i.e. a saving of HK$122 million in electrical consumption per year) while the thermal comfort for the occupants was also maintained

  16. Sustainable Environmental Education: Conditions and Characteristics Needed for a Successfully Integrated Program in Public Elementary Schools

    Science.gov (United States)

    Rieckenberg, Cara Rae

    This case study investigated what conditions and characteristics contributed to a successful environmental education program within elementary schools of a school district where environmental education was the mandate. While research does exist on practical application of environmental education within schools, little if any literature has been written or research conducted on schools actually implementing environmental education to study what contributes to the successful implementation of the program. To study this issue, 24 participants from a Midwestern school district were interviewed, six of whom were principals of each of the six elementary schools included in the study. All participants were identified as champions of environmental education integration within their buildings due to leadership positions held focused on environmental education. Analysis of the data collected via interviews revealed findings that hindered the implementation of environmental education, findings that facilitated the implementation of environmental education, and findings that indicated an environmental education-focused culture existed within the schools. Conditions and characteristics found to contribute to the success of these school's environmental education programs include: professional development opportunities, administrative support, peer leadership opportunities and guidance, passion with the content and for the environment, comfort and confidence with the content, ease of activities and events that contribute to the culture and student success. Keywords: environmental education, integration, leadership, teachers as leaders.

  17. Building Energy-Efficient Schools in New Orleans: Lessons Learned (Brochure)

    2011-12-01

    This case study presents the lessons learned from incorporating energy efficiency in the rebuilding and renovating of New Orleans K-12 schools after Hurricanes Katrina and Rita. Hurricane Katrina was the largest natural disaster in the United States, striking the Gulf Coast on August 29, 2005, and flooding 80% of New Orleans; to make matters worse, the city was flooded again only three weeks later by the effects of Hurricane Rita. Many of the buildings, including schools, were heavily damaged. The devastation of schools in New Orleans from the hurricanes was exacerbated by many years of deferred school maintenance. This case study presents the lessons learned from incorporating energy efficiency in the rebuilding and renovating of New Orleans K-12 schools after Hurricanes Katrina and Rita. The experiences of four new schools-Langston Hughes Elementary School, Andrew H. Wilson Elementary School (which was 50% new construction and 50% major renovation), L.B. Landry High School, and Lake Area High School-and one major renovation, Joseph A. Craig Elementary School-are described to help other school districts and design teams with their in-progress and future school building projects in hot-humid climates. Before Hurricane Katrina, New Orleans had 128 public schools. As part of the recovery planning, New Orleans Public Schools underwent an assessment and planning process to determine how many schools were needed and in what locations. Following a series of public town hall meetings and a district-wide comprehensive facility assessment, a Master Plan was developed, which outlined the renovation or construction of 85 schools throughout the city, which are expected to be completed by 2017. New Orleans Public Schools expects to build or renovate approximately eight schools each year over a 10-year period to achieve 21st century schools district-wide. Reconstruction costs are estimated at nearly $2 billion.

  5. Building occupancy diversity and HVAC (heating, ventilation, and air conditioning) system energy efficiency

    International Nuclear Information System (INIS)

    Yang, Zheng; Ghahramani, Ali; Becerik-Gerber, Burcin

    2016-01-01

    Approximately forty percent of total building energy consumption is attributed to HVAC (heating, ventilation, and air conditioning) systems that aim to maintain healthy and comfortable indoor environments. An HVAC system is a network with several subsystems, and there exist heat transfer and balance among the zones of a building, as well as heat gains and losses through a building's envelope. Diverse occupancy (diversity in terms of when and how occupants occupy a building) in spaces could result in increase of loads that are not actual demands for an HVAC system, leading into inefficiencies. This paper introduces a framework to quantitatively evaluate the energy implications of occupancy diversity at the building level, where building information modeling is integrated to provide building geometries, HVAC system layouts, and spatial information as inputs for computing potential energy implications if occupancy diversity were to be eliminated. An agglomerate hierarchical clustering-based iterative evaluation algorithm is designed for iteratively eliminating occupancy diversity. Whole building energy simulations for a real-world building, as well as virtual reference buildings demonstrate that the proposed framework could effectively quantify the HVAC system energy efficiency affected by occupancy diversity and the framework is generalizable to different building geometries, layouts, and occupancy diversities. - Highlights: • Analyze relationships between occupancy diversity and HVAC energy efficiency. • Integrate BIM for quantifying energy implications of occupancy diversity. • Demonstrate the effectiveness and generalizability of iterative evaluation algorithm. • Improve agglomerative hierarchical clustering process using heap data structure.

  10. Italmontaggi builds expertise Conquering monsoons, adverse conditions Bangladesh pipelines

    Energy Technology Data Exchange (ETDEWEB)

    1984-10-01

    Bangladesh natural gas pipeline projects have become a specialty for Italmontaggi Pte Ltd., Singapore-based gas pipeline contractor and engineering organization. The firm's latest project is a 35-mile, 24-in. gas pipeline, branching from the Bakhrabad-Chittagong main gas pipeline to the city gate station at Demra, near the capital city of Dacca. Gas is delivered to the Titas gas distribution system. The 35-mile turnkey project, valued at $25 million, included design, procurement, construction, and commissioning. A small pipeline was in existence from the Titas gas field to Dacca, but increased demand caused acute power shortages in the capital city's industrial areas. The new gas line will alleviate that problem. That project is a followup to Italmontaggi's successful completion of the major 108-mile, 24-in. main gas pipeline between the Bakhrabad gas fields, outside Dhaha, to the country's principal port and industrial center at Chittagong. Italmontaggi also installed 22 miles of ring main for the Chittagong gas distribution system. That included 12 miles of 24-in. and 10 miles of 16- and 20-in. to provide connections to industrial customers. Bangladesh lines difficult. The $45million contract for the Bakhrabad-toChittagong pipeline to Italmlontaggi, an autonomous offshoot of the Italian firm, resulted in a constant battle against hostile ground conditions, difficult access, and rapidly changing weather conditions. October-to- April is the dry season and Mayto-September is the wet season in this region. To keep the project moving, Italmontaggi developed two independent techniques for ground preparation during the wet season, and a pipelaying technique for the dry season. The new gas pipeline provides a major saving to the Bangladesh national economy as industries convert from oil to gas. Predicted savings are for more than $100 million in energy costs.

  14. Building of Environmental Literacy among Middle School Students: The Role of In-School, Out of School, and Psychological Factors

    Stevenson, Kathryn Tate

    Solving environmental challenges will require an environmentally literate citizenry, equipped with ecological knowledge, pro-environmental attitudes, problem-solving skills, and motivation toward environmentally responsible behaviors. This dissertation addresses three approaches to building environmental literacy (EL) among middle school students: through schools (Chapter 1), through activities outside of school (Chapter 2), and through understanding psychological factors that affect environmental perceptions (Chapter 3). Chapter 1. This study examined school-wide EE programs among middle schools in North Carolina, including the use of published EE curricula and time outdoors while controlling for teacher education level and experience, student demographics, and school attributes. Our sample included an EE group selected from schools with registered schoolwide EE programs, and a control group randomly selected from NC middle schools that were not registered as EE schools. Students were given an EL survey at the beginning and end of the spring 2012 semester. Use of published EE curricula, time outdoors, and having teachers with advanced degrees and mid-level teaching experience (between 3 and 5 years) were positively related with EL whereas minority status (Hispanic and black) was negatively related with EL. Results suggest that though school-wide EE programs may vary in effectiveness, the use of published EE curricula paired with time outdoors represents a promising strategy. Further, investments in both new and veteran teachers to build and maintain enthusiasm for EE may help to boost student EL levels. Middle school represents a pivotal time for influencing EL, as improvement was slower among older students. Differences in EL levels based on gender suggest boys and girls may possess complementary skills sets when approaching environmental issues. Our findings suggest ethnicity related disparities in EL levels may be mitigated by time spent in nature, especially

    2013-01-01

    Student turnover has many negative consequences for students and schools, and the high mobility rates of disadvantaged students may exacerbate inequality. Scholars have advised schools to reduce mobility by building and improving relationships with and among families, but such efforts are rarely tested rigorously. A cluster-randomized field experiment in 52 predominantly Hispanic elementary schools in San Antonio, TX, and Phoenix, AZ, tested whether student mobility in early elementary school was reduced through Families and Schools Together (FAST), an intervention that builds social capital among families, children, and schools. FAST failed to reduce mobility overall but substantially reduced the mobility of Black students, who were especially likely to change schools. Improved relationships among families help explain this finding. PMID:25346541

  19. Energy Performance and Optimal Control of Air-conditioned Buildings Integrated with Phase Change Materials

    Science.gov (United States)

    Zhu, Na

    This thesis presents an overview of the previous research work on dynamic characteristics and energy performance of buildings due to the integration of PCMs. The research work on dynamic characteristics and energy performance of buildings using PCMs both with and without air-conditioning is reviewed. Since the particular interest in using PCMs for free cooling and peak load shifting, specific research efforts on both subjects are reviewed separately. A simplified physical dynamic model of building structures integrated with SSPCM (shaped-stabilized phase change material) is developed and validated in this study. The simplified physical model represents the wall by 3 resistances and 2 capacitances and the PCM layer by 4 resistances and 2 capacitances respectively while the key issue is the parameter identification of the model. This thesis also presents the studies on the thermodynamic characteristics of buildings enhanced by PCM and on the investigation of the impacts of PCM on the building cooling load and peak cooling demand at different climates and seasons as well as the optimal operation and control strategies to reduce the energy consumption and energy cost by reducing the air-conditioning energy consumption and peak load. An office building floor with typical variable air volume (VAV) air-conditioning system is used and simulated as the reference building in the comparison study. The envelopes of the studied building are further enhanced by integrating the PCM layers. The building system is tested in two selected cities of typical climates in China including Hong Kong and Beijing. The cold charge and discharge processes, the operation and control strategies of night ventilation and the air temperature set-point reset strategy for minimizing the energy consumption and electricity cost are studied. This thesis presents the simulation test platform, the test results on the cold storage and discharge processes, the air-conditioning energy consumption and demand

    Full Text Available There has been a rising concern in reducing the energy consumption in buildings. Heating, ventilation and air-conditioning system is the biggest consumer of energy in buildings. In this study, management of the air-conditioning system of a building for efficient energy operation and comfortable environment is investigated. The strategy used in this work depends on classifying the rooms to three different groups: very important rooms, important rooms and normal rooms. The total mass flow rate is divided between all rooms by certain percentage using a fuzzy-logic system to get the optimum performance for each room. The suggested Building Management System (BMS was found capable of keeping errors in both temperature and humidity within the acceptable limits at different operating conditions. The BMS can save the chilled/hot water flow rate and the cooling/heating capacity of rooms.

    Full Text Available Energy consumption reduction under changing climate conditions is a major challenge in buildings design, where excessive energy consumption creates an economic and environmental burden. Improving thermal performance of the buildings through support applying phase change material (PCM is a promising strategy for reducing building energy consumption under future climate change. Therefore, this study aims to investigate the energy saving potentials in buildings under future climate conditions in the humid and snowy regions in the hot continental and humid subtropical climates of the east Asia (Seoul, Tokyo and Hong Kong when various PCMs with different phase change temperatures are applied to a lightweight building envelope. Methodology in this work is implemented in two phases: firstly, investigation of energy saving potentials in buildings through inclusion of three types of PCMs with different phase temperatures into the building envelop separately and use weather file in the present (2017; and, secondly, evaluation of the effect of future climate change on the performance of PCMs by analyzing energy saving potentials of PCMs with 2020, 2050 and 2080 weather data. The results show that the inclusion of PCM into the building envelope is a promising strategy to increase the energy performance in buildings during both heating and cooling seasons in Seoul, Tokyo and Hong Kong under future climate conditions. The energy savings achieved by using PCMs in those regions are electricity savings of 4.48–8.21%, 3.81–9.69%, and 1.94–5.15%, and gas savings of 1.65–16.59%, 7.60–61.76%, and 62.07–93.33% in Seoul, Tokyo and Hong Kong, respectively, for the years 2017, 2020, 2050 and 2080. In addition, BioPCM and RUBITHERMPCM are the most efficient for improving thermal performance and saving energy in buildings in the tested regions and years.

    The long-distant earthquake loading from Sumatra and Java Island had caused some slight damages to precast and reinforced concrete buildings in West Malaysia such as cracks on wall panels, columns and beams. Subsequently, the safety of existing precast concrete building is needed to be analyzed because these buildings were designed using BS 8110 which did not include the seismic loading in the design. Thus, this paper emphasizes on the seismic performance and dynamic behavior of precast school building constructed in Malaysia under three selected past earthquakes excitations ; El Centro 1940 North-South, El Centro East-West components and San Fernando 1971 using RUAUMOKO 2D program. This program is fully utilized by using prototype precast school model and dynamic non-linear time history analysis. From the results, it can be concluded that two-storey precast school building has experienced severe damage and partial collapse especially at beam-column joint under San Fernando and El Centro North-South Earthquake as its exceeds the allowable inter-storey drift and displacement as specified in Eurocode 8. The San Fernando earthquake has produced a massive destruction to the precast building under viscous damping, ξ = 5% and this building has generated maximum building displacement of 435mm, maximum building drift of 0.68% and maximum bending moment at 8458kNm.

    Full Text Available Malaysia is blessed with a rich legacy of heritage buildings with unique architectural and historical values. The heritage buildings become a symbol of the national identity of our country. Therefore, heritage buildings, as important monuments should be conserved well to ensure the extension of the building’s life span and to make sure continuity functions of the building for future generations. The aim of this study is to analyze the types of defects attached in school buildings over 100 years located in Perak. The data were collected in four different schools aged over 100 years in Perak. The finding of the study highlighted the types of defects which were categorized based on building elements, including external wall, roof, door, ceiling, staircase, column, internal wall, floor and windows. Finding showed that the type of defects occurred in school buildings over 100 years in Perak is the same as the other heritage buildings. This finding can be used by all parties to take serious actions in preventing defects from occurring in buildings over 100 years. This would ensure that buildings’ functional life span can be extended for future use.

    This paper presents the cooling performance of a water-to-refrigerant type ground heat source heat pump system (GSHP) installed in a school building in Korea. The evaluation of the cooling performance has been conducted under the actual operation of GSHP system in the summer of year 2007. Ten heat pump units with the capacity of 10 HP each were installed in the building. Also, a closed vertical typed-ground heat exchanger with 24 boreholes of 175 m in depth was constructed for the GSHP system. To analyze the cooling performance of the GSHP system, we monitored various operating conditions, including the outdoor temperature, the ground temperature, and the water temperature of inlet and outlet of the ground heat exchanger. Simultaneously, the cooling capacity and the input power were evaluated to determine the cooling performance of the GSHP system. The average cooling coefficient of performance (COP) and overall COP of the GSHP system were found to be {proportional_to}8.3 and {proportional_to}5.9 at 65% partial load condition, respectively. While the air source heat pump (ASHP) system, which has the same capacity with the GSHP system, was found to have the average COP of {proportional_to}3.9 and overall COP of {proportional_to}3.4, implying that the GSHP system is more efficient than the ASHP system due to its lower temperature of condenser.

  15. Energy Modelling and Automated Calibrations of Ancient Building Simulations: A Case Study of a School in the Northwest of Spain

    2017-06-01

    Full Text Available In the present paper, the energy performance of buildings forming a school centre in the northwest of Spain was analyzed using a transient simulation of the energy model of the school, which was developed with TRNSYS, a software of proven reliability in the field of thermal simulations. A deterministic calibration approach was applied to the initial building model to adjust the predictions to the actual performance of the school, data acquired during the temperature measurement campaign. The buildings under study were in deteriorated conditions due to poor maintenance over the years, presenting a big challenge for modelling and simulating it in a reliable way. The results showed that the proposed methodology is successful for obtaining calibrated thermal models of these types of damaged buildings, as the metrics employed to verify the final error showed a reduced normalized mean bias error (NMBE of 2.73%. It was verified that a decrease of approximately 60% in NMBE and 17% in the coefficient of variation of the root mean square error (CV(RMSE was achieved due to the calibration process. Subsequent steps were performed with the aid of new software, which was developed under a European project that enabled the automated calibration of the simulations.

    Full Text Available Exposure to volatile organic compounds (VOCs has been an indoor environmental quality (IEQ concern in schools and other buildings for many years. Newer designs, construction practices and building materials for “green” buildings and the use of “environmentally friendly” products have the promise of lowering chemical exposure. This study examines VOCs and IEQ parameters in 144 classrooms in 37 conventional and high performance elementary schools in the U.S. with the objectives of providing a comprehensive analysis and updating the literature. Tested schools were built or renovated in the past 15 years, and included comparable numbers of conventional, Energy Star, and Leadership in Energy and Environmental Design (LEED-certified buildings. Indoor and outdoor VOC samples were collected and analyzed by thermal desorption, gas chromatography and mass spectroscopy for 94 compounds. Aromatics, alkanes and terpenes were the major compound groups detected. Most VOCs had mean concentrations below 5 µg/m3, and most indoor/outdoor concentration ratios ranged from one to 10. For 16 VOCs, the within-school variance of concentrations exceeded that between schools and, overall, no major differences in VOC concentrations were found between conventional and high performance buildings. While VOC concentrations have declined from levels measured in earlier decades, opportunities remain to improve indoor air quality (IAQ by limiting emissions from building-related sources and by increasing ventilation rates.

    The thermal conditioning systems are responsible for almost half of the energy consump-tion by commercial buildings. In many European countries and in the USA, buildings account for around 40% of primary energy consumption and it is therefore vital to explore further ways to reduce the HVAC (Heating, Ventilation and Air Conditioning) system energy consumption. This thesis investigates the relationship between the energy genera-tion and storage systems for thermal conditioning of buildings (shorter: primary HVAC systems) and the conceptual building design. Certain building design decisions irreversibly influence a building's energy performance and, conversely, many generation and storage components impose restrictions on building design and, by their nature, cannot be introduced at a later design stage. The objective is, firstly, to develop a method to quantify this influence, in terms of primary HVAC system dimensions, its cost, emissions and energy consumption and, secondly, to enable the use of the developed method by architects during the conceptual design. In order to account for the non-stationary effects of the intermittent renewable energy sources (RES), thermal storage and for the component part load efficiencies, a time domain system simulation is required. An abstract system simulation method is proposed based on seven pre-configured primary HVAC system models, including components such as boil-ers, chillers and cooling towers, thermal storage, solar thermal collectors, and photovoltaic modules. A control strategy is developed for each of the models and their annual quasi-stationary simulation is performed. The performance profiles obtained are then used to calculate the energy consumption, carbon emissions and costs. The annuity method has been employed to calculate the cost.

    2017-11-01

    Full Text Available The building sector is an important stakeholder in the energy and environmental scenario of any country. It continues to grow across the world due to factors such as population growth, and economic and infrastructure development. Within the European Union, buildings account for 40% of the total energy requirements and 30% of carbon dioxide emissions. The building sector is keen to improve its sustainability standards and also to help achieve the 20-20-20 targets set by the European Union. The present work aims to design a nearly zero energy sports gymnasium building in Calolziocorte, Italy. Various sustainability techniques are applied in an integrated design project approach using ECOTECT software to undertake the energy modelling exercise. Firstly, the base-case is modelled with conventional building materials and the total energy demand is calculated. Duly considering the local climatic conditions, sustainable materials are chosen for walls, the floor, the roof, and windows and a 38% reduction is noted in the total energy demand of the building compared to the base-case. The impact of louvers as a passive design technique has also been examined on the total energy demand of the building. The monthly load/discomfort analysis is undertaken for various individual functions inside the building to identify the critical areas that consume more energy. The monthly load/discomfort analysis is performed with the proposed materials and the air infiltration rate is improved through the building envelope and 63% reduction is noted in the total energy demand of the building compared to the base-case. A solar access analysis is conducted to understand the on-site energy production and then the building net energy demand is calculated, which is reduced to 90% compared to the base-case.

    Due to the increasing need for complex residential buildings, it appears that people migrate into the high-density urban areas because the infrastructural facilities can be easily found in the modern metropolitan areas. Such rapid growth of urbanization creates congested residential buildings obstructing solar radiation and wind flow, whereas most urban residents spend 80-90% of their time indoor. Furthermore, the buildings were mostly built with average materials and construction detail. This causes high humidity condition for tenants that could promote mould growth. This study aims to analyse thermal comfort condition in complex residential building, Thailand for finding the passive solution to improve indoor air quality and respond to local conditions. The research methodology will be in two folds: 1) surveying on case study 2) analysis for finding the passive solution of reducing humidity indoor air The result of the survey indicated that the building need to find passive solution for solving humidity problem, that can be divided into two ways which raising ventilation and indoor temperature including increasing wind-flow ventilation and adjusting thermal temperature, for example; improving building design and stack driven ventilation. For raising indoor temperature or increasing mean radiant temperature, daylight can be passive solution for complex residential design for reducing humidity and enhance illumination indoor space simultaneous.

    2010-07-01

    For low-rise buildings in equatorial region, the roof is exposed to solar radiation longer than other parts of the envelope. Roofs are to be designed to reject heat and moderate the thermal impact. These are determined by the design and construction of the roofing system. The pitch of roof and the properties of construction affect the heat gain into the attic and subsequently the indoor temperature of the living spaces underneath. This finally influences the thermal comfort conditions of naturally ventilated buildings and cooling load of conditioned buildings. This study investigated the effect of insulated sloping roof on thermal energy performance of the building. A whole-building thermal energy computer simulation tool, Integrated Environmental Solution (IES), was used for the modelling and analyses. A building model with dimension of 4.0 m × 4.0 m × 3.0 m was designed with insulated roof and conventional construction for other parts of the envelope. A 75 mm conductive insulation material with thermal conductivity (k-value) of 0.034 Wm-1K-1 was installed underneath the roof tiles. The building was modelled with roof pitch angles of 0° , 15°, 30°, 45°, 60° and simulated for the month of August in Malaysian climate conditions. The profile for attic temperature, indoor temperature and cooling load were downloaded and evaluated. The optimum roof pitch angle for best thermal performance and energy saving was identified. The results show the pitch angle of 0° is able to mitigate the thermal impact to provide the best thermal condition with optimum energy savings. The maximum temperature difference between insulated and non-insulted roof for attic (AtticA-B) and indoor condition (IndoorA-B) is +7.8 °C and 0.4 °C respectively with an average energy monthly savings of 3.9 %.

This retrospective cohort study of 22,730 children and youth (grades 2-11) in San Jose, California, was conducted from 2007 through 2010. Health conditions were defined as chronic if reported in each of the first 2 years, and school performance was measured using standardized English language arts (ELA) and math assessments. Chronic health conditions were independently associated with low ELA and math performance, irrespective of ethnicity, socioeconomic status, or grade level. Adjusted odds ratios for the association between any chronic health condition and low ("basic or below") performance were 1.25 (95% confidence interval [CI], 1.16-1.36; P absenteeism had little effect on these results. The strongest associations were found for ADHD, autism, and seizure disorders, whereas a weak association was found for asthma before but not after adjusting for absenteeism, and no associations were found for cardiovascular disorders or diabetes. Chronic neurodevelopmental and seizure disorders, but not cardiovascular disorders or diabetes, were independently associated with low school performance among children and youth.

    Full Text Available The recast of the energy performance of buildings directive (EPBD describes a comparative methodological framework to promote energy efficiency and establish minimum energy performance requirements in buildings at the lowest costs. The aim of the cost-optimal methodology is to foster the achievement of nearly zero energy buildings (nZEBs, the new target for all new buildings by 2020, characterized by a high performance with a low energy requirement almost covered by renewable sources. The paper presents the results of the application of the cost-optimal methodology in two existing buildings located in the Mediterranean area. These buildings are a kindergarten and a nursery school that differ in construction period, materials and systems. Several combinations of measures have been applied to derive cost-effective efficient solutions for retrofitting. The cost-optimal level has been identified for each building and the best performing solutions have been selected considering both a financial and a macroeconomic analysis. The results illustrate the suitability of the methodology to assess cost-optimality and energy efficiency in school building refurbishment. The research shows the variants providing the most cost-effective balance between costs and energy saving. The cost-optimal solution reduces primary energy consumption by 85% and gas emissions by 82%–83% in each reference building.

    Full Text Available Malaysia initiated talks on building maintenance in 1971 during the Second Malaysia Plan of 1971-1975. Later, the government introduced the Building and Common Property (Maintenance and Management Act, 2007 to provide proper maintenance and management of buildings. School buildings are one of the important facilities for basic knowledge in everyday life. Accordingly, the maintenance of school buildings, which serve staff and students, needs considerable attention as effective maintenance protects capital investment, ensures the health and safety of the children, and supports educational performance. Based on a combination of literature survey and questionnaire appraisal, this study evaluates the maintenance practices in designated schools in Malaysia. Overall, the study showed that most of the school buildings do not possess their own maintenance management practices. Moreover, no preventive or planned maintenance was observed, and only emergency maintenance was applied when necessary. The study recommends the implementation of planned maintenance practices, which will be more effective than unplanned maintenance, mostly because of the reduction in repair costs.

    Particle count-based size distribution and PM(2.5) mass were monitored inside and outside an elementary school in Salt Lake City (UT, USA) during the winter atmospheric inversion season. The site is influenced by urban traffic and the airshed is subject to periods of high PM(2.5) concentration that is mainly submicron ammonium and nitrate. The school building has mechanical ventilation with filtration and variable-volume makeup air. Comparison of the indoor and outdoor particle size distribution on the five cleanest and five most polluted school days during the study showed that the ambient submicron particulate matter (PM) penetrated the building, but indoor concentrations were about one-eighth of outdoor levels. The indoor:outdoor PM(2.5) mass ratio averaged 0.12 and particle number ratio for sizes smaller than 1 microm averaged 0.13. The indoor submicron particle count and indoor PM(2.5) mass increased slightly during pollution episodes but remained well below outdoor levels. When the building was occupied the indoor coarse particle count was much higher than ambient levels. These results contribute to understanding the relationship between ambient monitoring station data and the actual human exposure inside institutional buildings. The study confirms that staying inside a mechanically ventilated building reduces exposure to outdoor submicron particles. This study supports the premise that remaining inside buildings during particulate matter (PM) pollution episodes reduces exposure to submicron PM. New data on a mechanically ventilated institutional building supplements similar studies made in residences.

    Conditioning buildings has been growing in number and are responsible for a significant portion of the energy used worldwide. The building energy use can be measured by the index of energy performance and specific fuel consumption (EC). The specific consumption is an index where the energy is normalized by the factors that affect energy use in order to obtain an index to explain variations in consumption. In this paper, we present a methodology to obtain a specific consumption that takes into account one of the factors that most affect energy use in these buildings, that is, the external temperature. The study is based on analysis of consumption of air conditioning system according to temperature. Through this analysis we obtain a function to facilitate the standardization of energy use, depending on the temperature outside. This methodology was tested in previous work on real buildings without stratification of energy, and this work will be presented a case study of a building whose energy measurement is stratified. The proposed index is the ratio between the energy consumption of air conditioning system corrected by the temperature through the function K(T). It was possible to demonstrate the efficiency of the index to eliminate the effect of temperature and thus to evaluate the evolution of specific consumption over the months analyzed. (author)

    SINTEF has in cooperation with the projecting group for Maela School, worked towards smart and general concepts to achieve good comfort with low energy consumption, low environmental impact and low investments. The project is called 'Maela smart building'. Based on conceptual solutions chosen for Maela School, this might be one of the leading school buildings in concern of energy efficiency. To be sure of achieving the target of needed energy to be less than 80 kWh/m{sub 2}, this assumes that the solutions satisfies the demands elaborated with basis in the energy target for the building together with heating and ventilation technical outfit run optimally. If the real consumption shall decrease towards calculated energy needs, the users have to be conscious not to contribute in wasting energy. Further the management of heat and ventilation has to function optimally, the setpoint for heating and ventilation has to be precise. In addition the operators have to have insight in how a building like this functions and the right skills to run it correct. Emphasis on alternatives contributing positively to architecture and good indoor environment in addition to focus on energy efficiency were considered for technical designing of the conceptual heat and ventilation solutions. Generally the need for ventilation channels is reduced to a minimum and the mechanical ventilation is dimensioned considering air quality. Thermic comfort is secured by means of passive attempt such as natural ventilation, sun screening and exploitation of thermic substance in ceiling, walls and floor. Choice of windows and walls with translucent isolation implied some increased risk for overheated teaching wings in second floor in warm and sunny periods. Since these premises because of school vacation in summer, normally is not in use in the summer, the attempts such as sun screening, natural ventilation and night cooling (ventilation of surplus heat during nights),were considered sufficient

    Modernization of school buildings involves more than a reduction of energy cost, due to the fact that the room climate of a school affects the learning success of its pupils. Users' demands on architecture and technical systems are highly complex: Rooms are used at different times and for different lengths of time, there are vacation times when the building is not used, and the rooms must meet high demands in terms of air change, lighting, acoustics and blinding as well as in terms of safety, hygiene and pollutant-free air. All this necessitates an integral sanitation concept that takes account of all aspects. Further, the modernization of school buildings should also serve to enhance the pupils' environmental and energy awareness. This guide takes account of all these aspects. (orig./AKB)

However, it is close to a seismically active plate boundary, the inter-plate boundary between the Indo-Australian and Eurasian Plates. Occasionally, tremors can be felt throughout the region even when active faults are located several hundred kilometers away. Lessons learnt from past events, active earthquakes located far from the existing building can cause potential damage. Thus, fragility curves become an essential ...

  16. Optimization and Performance Study of Select Heating Ventilation and Air Conditioning Technologies for Commercial Buildings

    Kamal, Rajeev

    Buildings contribute a significant part to the electricity demand profile and peak demand for the electrical utilities. The addition of renewable energy generation adds additional variability and uncertainty to the power system. Demand side management in the buildings can help improve the demand profile for the utilities by shifting some of the demand from peak to off-peak times. Heating, ventilation and air-conditioning contribute around 45% to the overall demand of a building. This research studies two strategies for reducing the peak as well as shifting some demand from peak to off-peak periods in commercial buildings: 1. Use of gas heat pumps in place of electric heat pumps, and 2. Shifting demand for air conditioning from peak to off-peak by thermal energy storage in chilled water and ice. The first part of this study evaluates the field performance of gas engine-driven heat pumps (GEHP) tested in a commercial building in Florida. Four GEHP units of 8 Tons of Refrigeration (TR) capacity each providing air-conditioning to seven thermal zones in a commercial building, were instrumented for measuring their performance. The operation of these GEHPs was recorded for ten months, analyzed and compared with prior results reported in the literature. The instantaneous COPunit of these systems varied from 0.1 to 1.4 during typical summer week operation. The COP was low because the gas engines for the heat pumps were being used for loads that were much lower than design capacity which resulted in much lower efficiencies than expected. The performance of equivalent electric heat pump was simulated from a building energy model developed to mimic the measured building loads. An economic comparison of GEHPs and conventional electrical heat pumps was done based on the measured and simulated results. The average performance of the GEHP units was estimated to lie between those of EER-9.2 and EER-11.8 systems. The performance of GEHP systems suffers due to lower efficiency at

    On June 5th, 2015 a severe earthquake with a moment Magnitude of 6.0 occurred in Ranau, Malaysia. Depth of the epicenter is 10 km. Due to the earthquake, many facilities were damaged and 18 people were killed due to rockfalls [1]. Because the British Standard (BS) is adopted as a regulation for built buildings in Malaysia, the seismic force is not considered in the structural design. Therefore, the seismic resistance of Malaysian buildings is unclear. To secure the human life and building safety, it is important to grasp seismic resistance of the building. The objective of this study is to evaluate the seismic resistance of the existing buildings in Malaysia built by the British Standard. A school building that was damaged at the Ranau earthquake is selected as the target building. The building is a four story building and the ground floor is designed to be a parking space for the staff. The structural types are infill masonries where main frame is configured by reinforced concrete columns and beams and brick is installed inside the frame as walls. Analysis is performed using the STERA_3D software that is the software to analyze the seismic performance of buildings developed by one of the authors. Firstly, the natural period of the building is calculated and compared with the result of micro-tremor measurement. Secondly, the nonlinear push-over analysis was conducted to evaluate the horizontal load bearing capacity of the building. Thirdly, the earthquake response analysis was conducted using the time history acceleration data measured at the Ranau earthquake by the seismograph installed at Kota Kinabalu. By comparing the results of earthquake response analysis and the actual damage of the building, the reason that caused damage to the building is clarified.

    The containment buildings in a nuclear power plant (NPP) are final barriers against the exposure of harmful radiation materials at severe accident condition. Since the accident at Three Mile Island nuclear plant in 1979, it has become necessary to evaluate the internal pressure capacity of the containment buildings for the assessment of the safety of nuclear power plants. According to this necessity, many researchers including Yonezawa et al. and Hu and Lin analyzed the ultimate capacity of prestressed concrete containments subjected to internal pressure which can be occurred at sever accident condition. Especially in Wolsong nuclear power plant, the Unit 1 containment structures were constructed in the late 1970 to early 1980, so that the end of its service life will be reached in near future. Since that the complete decommission and reconstruction of the NPP may cause a huge expenses, an extension of the service time can be a cost-effective alternative. To extend the service time of NPP, an overall safety evaluation of the containment building under severe accident condition should be performed. In this study, we assessed the pressure capacity of Wolsong Unit 1 containment building under severe accident, and estimated the responses at all of the probable critical areas. Based on those results, we found the significant failure modes of Wolsong Unit 1 containment building with respect to the severe accident condition. On the other hand, for the aged NPP, the degradation of their structural performance must also be explained in the procedure of the internal pressure capacity evaluation. Therefore, in this study, we performed a parametric study on the degradation effects and evaluated the internal pressure capacity of Wolsong Unit 1 containment building with considering aging and degradation effects

One of the results as implemented in many European countries derived from such tests consisted of mandatory technical instructions issued by nuclear regulatory bodies on the analysis of potential risk of flammable gases in attached buildings to containment. The current study addresses the key aspects of the analysis of flammable gases leaking to auxiliary buildings attached to Westinghouse large-dry PWR containment for the specific situation where mitigating systems to prevent flammable gases to grow up inside containment are available, and containment integrity is preserved – hence avoiding isolation system failure. It also provides a full practical exercise where lessons learned derived from the current study – hence limited to the imposed boundary conditions – are applied. The leakage of gas from the containment to the support buildings is based on separate calculations using the EPRI-owned Modular Accident Analysis Program, MAAP4.07. The FATE™ code (facility Flow, Aerosol, Thermal, and Explosion) was used to model the transport and distribution of leaked flammable gas (H{sub 2} and CO) in the penetration buildings. FATE models the significant mixing (dilution) which occurs as the released buoyant gas rises and entrains air. Also, FATE accounts for the condensation of steam on room surfaces, an effect which acts to concentrate flammable gas. The results of the analysis show that during a severe accident, flammable conditions are unlikely to occur in compartmentalized buildings such as the one used in the

    Public health has been an enormously effective instrument for improving life expectancy and quality of life. Historically a sphere of governmental activity led by physicians and staffed by sanitarians and nurses, public health has evolved to become a multi-facetted field of societal activity. It engages many agencies and community action in reducing infectious and non-communicable diseases as well as many aspects of lifestyle and health equity. Education for an adequate professional workforce is one of its key functions. Schools of public health have fulfilled this role only partly even in developed countries, but in countries in transition and in low-income countries the problem is much more acute. We discuss the role of mentoring of new schools calling for strong public and private donor support for this as a key issue in global health.

    Full Text Available This article discusses the design of data collection instruments that include the opinions of blind students, in accordance with the principles of Universal Design (UD. The aim of this study is to understand the importance of adapting data collection instruments for the inclusion of disabled persons in field research in Architecture and Design, among other fields. The data collection instruments developed were a play interview with a tactile map and a 3D survey with the use of tactile models. These instruments sought to assess the school environment experienced by blind students. The study involved students from the early years of a school for the blind who had not yet mastered the Braille system. The participation of these students was evaluated. A multidisciplinary team consisting of architects, designers, educators, and psychologists lent support to the study. The results showed that the data collection instruments adapted to blind students were successful in making the group of authors examine questions regarding UD. An analysis of the participatory phase showed that the limitations resulting from blindness determine the specificities in the adaptation and implementation process of the instruments in schools. Practical recommendations for future studies related to instruments in the UD thematic are presented. This approach is in line with the global trend of including disabled persons in society based on these users’ opinions concerning what was designed by architects and designers.

Despite the fact that operations promoted by the Government haven’t been effective so far, the European Union encourages deep retrofit interventions towards the standard 'Nearly Zero Energy Buildings'. This approach necessarily implies a systemic knowledge of the buildings, which can be achieved with different levels of detail, through preliminary energy audits, audits, and more detailed and multi-criteria Post-Occupancy Evaluations.

    Education and training of students of architecture, industrial design, planning and environmental sciences in solar energy utilization, as practiced at the University of Calgary, is described. Classes are relatively small, which allows for considerable flexibility in terms of the different modes of instruction. Lectures, case studies, field trips and workshops all have their place, although the most effective and most popular mode of instruction is the hands-on approach in building and installing a solar heating system. During the course, the students build various types of solar cookers and concentrating solar collectors, including air-type and water-type flat plate collectors. Usually one solar component is built by each class, but previous projects are available for examination and monitoring. This paper elaborates upon the pedagogical basis of shop experience for architectural students. In this context it addresses issues related to shop space, materials, construction, installation testing and monitoring, as well as safety and performance of the student-constructed solar systems. 3 refs., 9 figs.

    To find out the leak characteristic of research reactor 'HANARO' building in a typhoon condition MELCOR code which normally is used to simulate severe accident behavior in a nuclear power plant was used to simulate the leak rate of air and fission products from reactor hall after the shutdown of the ventilation system of HANARO reactor building. For the simulation, HANARO building was designed by MELCOR code and typhoon condition passed through Daejeon in 2012 was applied. It was found that the leak rate is 0.1%·day{sup -1} of air, 0.004%·day{sup -1} of noble gas and 3.7×10{sup -5}%·day{sup -1} of aerosol during typhoon passing. The air leak rate of 0.1%·day can be converted into 1.36 m{sup 3}·hr{sup -1} , but the design leak rate in HANARO safety analysis report was considered as 600 m3·hr{sup -1} under the condition of 20 m·sec{sup -1} wind speed outside of the building by typhoon. Most of fission products during the maximum hypothesis accident at HANARO reactor will be contained in the reactor hall, so the direct radiation by remained fission products in the reactor hall will be the most important factor in designing emergency preparedness for HANARO reactor.

    Understanding the earthquake phenomena and their effects is an important step toward the education of population and aims to raise the awareness about the earthquake risk and possible mitigation actions. In this sense, The Romanian Educational Seismic Network project represents an efficient communication tool, allowing teaching and learning about the earthquakes and seismic wave impact through experimental practices and educational activities. The seismic network consist of nine SEP seismometers installed in high-schools from the most important seismic areas (Vrancea, Banat, Făgăraş, Dobrogea), vulnerable cities (Bucharest, Iasi) or high populated places (Cluj, Sibiu, Timisoara, Zalău) and is coordinated by the National Institute of Earth Physics from Bucharest. Once installed, the seismic network is the starting point of activities for students through an e-learning platform. Some objectives are aimed: - To train students and teachers how to make analysis and interpretation of seismological data; - To make science more interesting for students; - To improve the participation rates in physical sciences for students; - To raise awareness of geoscience as a scientific discipline for pre-university students; - To promote the installation and effective use of educational seismographs and seismic data; - To reinforce and develop relationships between participating schools and research institutes; - To create an earthquake database this will be used by students and teachers for educational purposes. Different types of practical activities using educational seismometer, designed by researchers for students, are described in educational materials and in the web platform project. Also we encourage the teachers from the participating schools to share their experiences and produce new didactic tools for the classroom. This collaborative work could illustrate the conjugated efforts of researchers and teachers for a better education and awareness of the risk culture

    2017-08-01

    Full Text Available Mathematics teachers need to take on the role of counselors in addressing the math anxious in today's math classrooms. This paper looks at the impact math anxiety has on the future of young adults in our high-tech society. Teachers and professional school counselors are encouraged to work together to prevent and reduce math anxiety. It is important that all students feel confident in their ability to do mathematics in an age that relies so heavily on problem solving, technology, science, and mathematics. It really is a school's obligation to see that their students value and feel confident in their ability to do math, because ultimately a child's life: all decisions they will make and careers choices may be determined based on their disposition toward mathematics. This paper raises some interesting questions and provides some strategies (See Appendix A for teachers and counselors for addressing the issue of math anxiety while discussing the importance of developing mathematically confident young people for a high-tech world of STEM.

  17. Performance advancement of solar air-conditioning through integrated system design for building

    International Nuclear Information System (INIS)

    Fong, K.F.; Lee, C.K.

    2014-01-01

    This study is to advance the energy performance of solar air-conditioning system through appropriate component integration from the absorption refrigeration cycle and proper high-temperature cooling. In the previous studies, the solar absorption air-conditioning using the working pair of water – lithium bromide (H 2 O–LiBr) is found to have prominent primary energy saving than the conventional compression air-conditioning for buildings in the hot-humid climate. In this study, three integration strategies have been generated for solar cooling, namely integrated absorption air-conditioning; integrated absorption-desiccant air-conditioning; and integrated absorption-desiccant air-conditioning for radiant cooling. To realize these ideas, the working pair of ammonia – water (NH 3 –H 2 O) was used in the absorption cycle, rather than H 2 O–LiBr. As such, the evaporator and the condenser can be separate from the absorption refrigeration cycle for the new configuration of various integrated design alternatives. Through dynamic simulation, the year-round primary energy saving of the proposed integration strategies for solar NH 3 –H 2 O absorption air-conditioning systems could be up to 50.6% and 25.5%, as compared to the conventional compression air-conditioning and the basic solar H 2 O–LiBr absorption air-conditioning respectively. Consequently, carbon reduction of building air-conditioning can be achieved more effectively through the integrated system design in the hot and humid cities. - Highlights: • Three integration strategies, IAAU, IADAU and IADAU-RC, are proposed to advance solar air-conditioning. • NH 3 –H 2 O is adopted for absorption refrigeration instead of H 2 O–LiBr. • Separate evaporator and condenser, desiccant cooling and radiant cooling are designed for IADAU-RC. • IADAU-RC can have 50.6% primary energy saving against the conventional air-conditioning

  19. Indoor radon levels in Columbus and Franklin county, Ohio residences, commercial buildings, and schools

    International Nuclear Information System (INIS)

    Grafton, H.E.

    1990-01-01

    In this paper data is presented for 2 residential radon surveys, one survey of city-owned buildings, and survey of Columbus Public Schools. The first residential survey used volunteer participants and employed a 48 hour activated carbon measurement: 4425 measurements in the data. The second survey consisted of 120 randomly selected residences in which alpha track detectors were placed for from 60 to 120 days. A survey of 52 city-owned buildings in which screening measurements were obtained using activated carbon, alpha track, and E-PERM radon detectors is included in the data. Also a survey of 25 Columbus Public Schools in which E-PERM radon monitors were used to obtain measurements is detailed in the data. More than 72% of the volunteer survey residences showed screening measurements of 4.0 pCi/L or greater while the random survey revealed 92% of the residences with radon levels of 4.0 pCi/L or higher. Schools tested in the survey also showed elevated radon levels with 20% of the tested structures with an average radon level of 4.0 pCi/L. Work is still in progress on city-owned buildings and Columbus Schools. The authors conclude that any owner or lessor of occupied buildings in Franklin County, Ohio should perform screening measurements and should be prepared to also perform follow-up measurements

    Implementation of vocational learning in accordance with the 2013 curriculum must meet the criteria, one of which is learning to be consistent with advances in technology and information. Technology-based learning in vocational commonly referred to as E-Learning, online (in the network) and WBL (Web-Based Learning). Facts on the ground indicate that based learning technology and information on Vocational High School of Building Engineering is still not going well. The purpose of this research is to know: advantages and disadvantages of learning with E-Learning, conformity of learning with E-Learning with characteristics of students on Vocational High School of Building Engineering and effective learning method based on E-Learning for students on Vocational High School of Building Engineering. Research done by literature method, get the following conclusion as follow: the advantages of E-Learning is learning can be done anywhere and anytime, efficient in accessing materials and tasks, ease of communication and discussion; while the shortage is the need for additional costs for good internet access and lack of social interaction between teachers and students. E-learning is appropriate to basic knowledge competencies, and not appropriate at the level of advanced competencies and skills. Effective E-Learning Based Learning Method on Vocational High School of Building Engineering is a Blended method that is a mix between conventional method and e-learning.

    Investigations on Palaeonummulites venosus using the natural laboratory approach for determining chamber building rate, test diameter increase rate, reproduction time and longevity is based on the decomposition of monthly obtained frequency distributions based on chamber number and test diameter into normal-distributed components. The shift of the component parameters 'mean' and 'standard deviation' during the investigation period of 15 months was used to calculate Michaelis-Menten functions applied to estimate the averaged chamber building rate and diameter increase rate under natural conditions. The individual dates of birth were estimated using the inverse averaged chamber building rate and the inverse diameter increase rate fitted by the individual chamber number or the individual test diameter at the sampling date. Distributions of frequencies and densities (i.e. frequency divided by sediment weight) based on chamber building rate and diameter increase rate resulted both in a continuous reproduction through the year with two peaks, the stronger in May /June determined as the beginning of the summer generation (generation1) and the weaker in November determined as the beginning of the winter generation (generation 2). This reproduction scheme explains the existence of small and large specimens in the same sample. Longevity, calculated as the maximum difference in days between the individual's birth date and the sampling date seems to be round about one year, obtained by both estimations based on the chamber building rate and the diameter increase rate.

    Indoor air is contaminated with microorganisms coming from both the atmospheric air and sources present in premises. The aim of this study was to analyze the concentrations of biological agents in office buildings, dependending on ventilation/air conditioning system and season. The study covered office buildings (different in the system of ventila-tion/air conditioning). Air samples for assessing the levels of inhalable dust, endotoxins and (1-->3)-beta-D-glucans, were taken at the selected stationary points of each building during summer and winter. The air was sampled for 6 h, using portable sets consisting of the GilAir 5 pump and the head filled with a filter of fiber glass. The samples for the presence of airborne bacteria and fungi were collected twice during the day using the impaction method. Average concentrations of inhalable dust, bacteria, fungi, endotoxins and (1-->3)-beta-D-glucans in office premises were 0.09 mg/m3, 6.00 x 10(2) cfu/m3, 4.59 x 10(1) cfu/m3, 0.42 ng/m3 and 3.91 ng/m3, respectively. Higher concentrations of the investigated agents were found in summer. In premises with air conditioning concentrations of airborne fungi, (1-->3)-beta-D-glucans and inhalable dust were significantly lower in winter. In summer the trend was reverse except for (1-->3)-beta-D-glucans. Concentrations of biological agents were affected by the season and the presence of air conditioning. Concentrations of inhalable dust, bacteria, fungi, endotoxins and (1-->3)-beta-D-glucans, observed inside the office buildings, were significantly higher in summer than in winter. The presence of the air conditioning system modified in various ways the levels of biological agents. Its influence was greater on the concentration of fungi and (1-->3)-beta-D-glucans than on that of bacteria and endotoxins.

  7. Assessment of Passive vs. Active Strategies for a School Building Design

    Directory of Open Access Journals (Sweden)

    2015-11-01

    Full Text Available This paper presents a simulation study to reduce heating and cooling energy demand of a school building in Seoul Metropolitan Area, Korea. The aim of this study was to estimate the impact of passive vs. active approaches on energy savings in buildings using EnergyPlus simulation. By controlling lighting, the energy saving of the original school building design was found most significant, and increased by 32% when the design was improved. It is noteworthy that energy saving potential of each room varies significantly depending on the rooms’ thermal characteristics and orientation. Thus, the analysis of energy saving should be introduced at the individual space level, not at the whole building level. Additionally, the simulation studies should be involved for rational decision-making. Finally, it was concluded that priority should be given to passive building design strategies, such as building orientation, as well as control and utilization of solar radiation. These passive energy saving strategies are related to urban, architectural design, and engineering issues, and are more beneficial in terms of energy savings than active strategies.

    Geospatial technology has widespread usage in development planning and resource management. It offers pragmatic tools to help urban and regional planners to realize their goals. On the request of Ministry of Urban Development, Govt. of India, the Indian Institute of Remote Sensing (IIRS), Dehradun has taken an initiative to study the model syllabi of All India Council for Technical Education for planning curricula of Bachelor and Master (five disciplines) programmes. It is inferred that geospatial content across the semesters in various planning fields needs revision. It is also realized that students pursuing planning curricula are invariably exposed to spatial mapping tools but the popular digital drafting software have limitations on geospatial analysis of planning phenomena. Therefore, students need exposure on geospatial technologies to understand various real world phenomena. Inputs were given to seamlessly merge and incorporate geospatial components throughout the semesters wherever seems relevant. Another initiative by IIRS was taken to enhance the understanding and essence of space and geospatial technologies amongst the young minds at 10+2 level. The content was proposed in a manner such that youngsters start realizing the innumerable contributions made by space and geospatial technologies in their day-to-day life. This effort both at school and college level would help in not only enhancing job opportunities for young generation but also utilizing the untapped human resource potential. In the era of smart cities, higher economic growth and aspirations for a better tomorrow, integration of Geospatial technologies with conventional wisdom can no longer be ignored.

    Perley, M. M.; Guo, J.

    2016-12-01

    India's National School Safety Program (NSSP) aims to assess all government schools in earthquake prone regions of the country. To supplement the Mizoram State Government's recent survey of 141 government schools, we screened an additional 16 private and 4 government schools for structural vulnerabilities due to earthquakes, as well as landslide hazards, in Mizoram's capital of Aizawl. We developed a geomorphologically derived landslide susceptibility matrix, which was cross-checked with Aizawl Municipal Corporation's landslide hazard map (provided by Lettis Consultants International), to determine the geologic hazards at each school. Our research indicates that only 7% of the 22 assessed school buildings are located within low landslide hazard zones; 64% of the school buildings, with approximately 9,500 students, are located within very high or high landslide hazard zones. Rapid Visual Screening (RVS) was used to determine the structural earthquake vulnerability of each school building. RVS is an initial vulnerability assessment procedure used to inventory and rank buildings that may be hazardous during an earthquake. Our study indicates that all of the 22 assessed school buildings have a damageability rating of Grade 3 or higher on the 5-grade EMS scale, suggesting a significant vulnerability and potential for damage in buildings, ranging from widespread cracking of columns and beam column joints to collapse. Additionally, 86% of the schools we visited had reinforced concrete buildings constructed before Aizawl's building regulations were passed in 2007, which can be assumed to lack appropriate seismic reinforcement. Using our findings, we will give recommendations to the Government of Mizoram to prevent unnecessary loss of life by minimizing each school's landslide risk and ensuring schools are earthquake-resistant.

    M. A. Rutkowski

    2017-01-01

    Full Text Available Solar systems are actively applied for heat supply of buildings in Europe. Usage of solar energy for heat supply of residential buildings is considered as rather efficient for the Republic of Belarus because total amount of direct and scattered solar radiation entering horizontal surface is equivalent to an average European index for the climate of Belarus. The paper analyzes an existing dependence on determination of solar system efficiency and proposes an amended formula for calculations while designing solar consumption systems and its legitimacy has been experimentally proved. A scheme of an experimental unit with explanations and a brief description for execution of experiments and main results of the completed investigations have been presented in the paper. Experiments have been carried out for solar systems with natural and forced coolant circulation. Attention has been paid to obtaining maximum possible temperature potential of the coolant during operation of the solar system within periods of high and low solar radiation intensity. Recommendations on practical application of solar systems for multi-storey residential buildings houses and mansion-type houses have been given in the paper. The paper presents technological principles of constructing “passive” solar heating devices. A comparison of traditionally applied and proposed alternative solar systems has been made for operational conditions in Belarus. The paper proposes a solar system for hot water supply of multi-storey buildings. The proposed system has found its first realization in the Republic while designing and constructing an energy-efficient demonstration 10-storey residential building in Mogilev within the framework of the UN Development Program project and Global Environment Fund “Improvement of energy efficiency for residential buildings in the Republic of Belarus”

    Craig, A.B.; Leovie, K.W.

    1991-01-01

    Recent concerns over elevated levels of radon in existing buildings have prompted the design and construction of a number of school buildings that either are radon resistant or incorporate features that facilitate post-construction mitigation if needed. This paper described initial results of a study of several schools with radon-resistant features that were recently constructed in the northeastern U.S. These designs are generally based on experience with radon mitigation in existing houses and schools and radon-resistant new house construction. The study was limited to slab-on-grade schools, where the most common radon-resistant school design is active subslab depressurization (ASD). The additional construction costs for eight schools built with ASD ranged from $3 to $11 per square meter of slab area. The radon contractors who designed these systems have tended to overdesign the radon-reduction systems in the absence of specific written guidance to follow to lessen potential liability in the event of system failure. Design features include detailed sealing of all slab cracks, multiple exhaust stacks, and extensive subslab piping

    2005-04-01

    Detailed acoustical measurements were made in 34 active elementary school classrooms with typical rectangular room shape in schools near Ottawa, Canada. There was an average of 21 students in classrooms. The measurements were made to obtain accurate indications of the acoustical quality of conditions for speech communication during actual teaching activities. Mean speech and noise levels were determined from the distribution of recorded sound levels and the average speech-to-noise ratio was 11 dBA. Measured mid-frequency reverberation times (RT) during the same occupied conditions varied from 0.3 to 0.6 s, and were a little less than for the unoccupied rooms. RT values were not related to noise levels. Octave band speech and noise levels, useful-to-detrimental ratios, and Speech Transmission Index values were also determined. Key results included: (1) The average vocal effort of teachers corresponded to louder than Pearsons Raised voice level; (2) teachers increase their voice level to overcome ambient noise; (3) effective speech levels can be enhanced by up to 5 dB by early reflection energy; and (4) student activity is seen to be the dominant noise source, increasing average noise levels by up to 10 dBA during teaching activities.

    Highlights: → Impact of PCM on the energy consumption and peak load demand as well as electricity cost of air-conditioned buildings. → Impact of load shifting control on energy consumption, peak load and electricity cost of air-conditioned PCM buildings. → Impact of demand limiting control on energy consumption, peak load and electricity cost of air-conditioned PCM buildings. → Energy/cost effects of different control strategies and use of PCM in energy-plus-demand-based pricing policy. → Energy/cost effects of different control strategies and use of PCM in time-based pricing policy. - Abstract: Studies are conducted to investigate the impacts of shape-stabilized phase change material (SSPCM) and different control strategies on the energy consumption and peak load demand as well as electricity cost of building air-conditioning systems at typical summer conditions in two climates (subtropical and dry continental climates). An office building using a typical variable air volume (VAV) air-conditioning system was selected and simulated as the reference building in this study. Its envelopes were enhanced by integrating the SSPCM layers into its walls while the air-conditioning system and other configurations of the building remained unchanged. The building system was tested under two typical weather conditions and two typical electricity pricing policies (i.e. time-based pricing and energy-plus-demand-based pricing). Test results show that the use of SSPCM in the building could reduce the building electricity cost significantly (over 11% in electricity cost reduction and over 20% in peak load reduction), under two pricing policies by using load shifting control and demand limiting control respectively. This paper presents the test results and the evaluation on the energy performance and the optimal control strategies of air-conditioned commercial buildings with envelopes enhanced by SSPCM.

    The inhalation of 222 Rn (radon) is the most important reason for lung cancer as a result of smoking. The cause for enhanced radon concentration in the air of buildings is mostly the building ground. But also building products can lead to increased radon concentrations in indoor air when the products contain raw materials or residues with higher contents of 226 Ra (radium), especially in combination with low air exchange rates. For a realistic estimation of radon concentrations it is helpful to perform emission tests on the basis of emission test chambers. Emissions test chambers are already used successfully for the measurement of volatile organic compounds (VOC) emitted from different materials and products. The analysis of radon in air was performed with a test device based on the principle of ionisation chamber (ATMOS 12 D). It could be show that radon concentrations emitted from building materials can be determined reliably if certain boundary conditions such as temperature, relative humidity and especially area specific air flow rate are met. It was also shown that reduced area specific air flow rates or reduced air exchange rates lead to higher radon concentrations. It is remarkable that no conclusion can be drawn from the activity concentration of radium to the radon concentration in the air. Therefore in some cases much higher radon concentrations in air were determined that had been expected. Obviously diffusion within the material plays an important role. (orig.)

    The present paper deals with the energy performance, energy classification and rating and the global environmental quality of school buildings. A new energy classification technique based on intelligent clustering methodologies is proposed. Energy rating of school buildings provides specific information on their energy consumption and efficiency relative to the other buildings of similar nature and permits a better planning of interventions to improve its energy performance. The overall work reported in the present paper, is carried out in three phases. During the first phase energy consumption data have been collected through energy surveys performed in 320 schools in Greece. In the second phase an innovative energy rating scheme based on fuzzy clustering techniques has been developed, while in the third phase, 10 schools have been selected and detailed measurements of their energy efficiency and performance as well as of the global environmental quality have been performed using a specific experimental protocol. The proposed energy rating method has been applied while the main environmental and energy problems have been identified. The potential for energy and environmental improvements has been assessed.

    In Turkey, as well as many other developing countries, the significance of sustainable education buildings has only recently become recognized and the issue of sustainability issue has not been sufficiently involved in laws and regulations. In this study, first of all architectural sustainability with basic design criteria has been explained. After that selected type primary school project in Turkey has been evaluated according to the sustainable design criteria. Type project of school buildings significantly limits the sustainability performance expected from buildings. It is clear that type projects shorten the planning time as they include a designing process that is independent of settlement and they are repeated in various places with different characteristics, indeed. On the other hand; abundance of disadvantages such as the overlook of the natural physical and structural properties of the location mostly restricts the sustainable design of the building. For sustainable buildings, several factors such as the environment, land, climate, insolation, direction etc. shall be taken into consideration at the beginning stage. Therefore; implementation of type projects can be deemed to be inappropriate for sustainability.

    Full Text Available Using stories in teaching foreign language, it forces the teacher to be crative and innovative to encourage the young learners to enjoy reading stories. The teacher has to be smart to select which one approaches or methods which can enhance learning foreign language and character building in the teaching foreign language process.The storyline approach was specifically designed for the use at primary schools. The storyline method (Storyline for teaching children at primary schools was mainly developed in 1967 by a team of teachers from Jordanhill College of Education (now known as University of Strathclyde in Glasgow, Scotland. The primary schools in Scotland use a curriculum that involves integration of new topics, such as environmental studies and expressive arts, in their teaching foreign language process. This method could be one of alternative method that be applied in teaching foreign language to Elementary School or English Courses for Children in Indonesia.

    Full Text Available There has been a rising concern in reducing the energy consumption in building. Heating ventilation and air condition system is the biggest consumer of energy in building. In this study, fuzzy logic control of the air conditioning system of building for efficient energy operation and comfortable environment is investigated. A theoretical model of the fan coil unit (FCU and the heat transfer between air and coolant fluid is derived. The controlled variables are the room temperature and relative humidity and control consequents are the percentage of chilled and hot water flow rates at summer and the percentage of hot water and steam injected flow rates at winter. A computer simulation has been conducted and fuzzy control results are compared with that of conventional Proportional-Integral-Derivative control. It was found that the proposed control strategy satisfies the space load and at the same time to achieve the comfort zone, as defined by the ASHRAE code. Meanwhile PID control fails to adjust the room temperature at part-load operations. It has been demonstrated that fuzzy controller operation is more efficient and consumes less energy than PID control.

    2009-06-17

    This paper presents a freely available Modelica library for building heating, ventilation and air conditioning systems. The library is based on the Modelica.Fluid library. It has been developed to support research and development of integrated building energy and control systems. The primary applications are controls design, energy analysis and model-based operation. The library contains dynamic and steady-state component models that are applicable for analyzing fast transients when designing control algorithms and for conducting annual simulations when assessing energy performance. For most models, dimensional analysis is used to compute the performance for operating points that differ from nominal conditions. This allows parameterizing models in the absence of detailed geometrical information which is often impractical to obtain during the conceptual design phase of building systems. In the first part of this paper, the library architecture and the main classes are described. In the second part, an example is presented in which we implemented a model of a hydronic heating system with thermostatic radiator valves and thermal energy storage.

    Some researchers have demonstrated that passive moisture transfer between indoor air and hygroscopic structures has the potential to moderate variations of indoor air relative humidity and, thus, to improve comfort and PAQ [Simonson CJ, Salonvaara M, Ojalen T. The effect of structures on indoor humidity-possibility to improve comfort and perceived air quality. Indoor Air 2002; 12: 243-51; Simonson CJ, Salonvaara M, Ojalen T.

The main objective of this study is to show the internal wall coating effect on indoor air conditions and, as a consequence of this, in comfort conditions and PAQ. In a previous paper [Orosa JA, Baalina A. Passive climate control in Spanish office buildings for long periods of time. Building and Environment 2008], we analysed the influence of permeable and impermeable materials on indoor air conditions, during the unoccupied period, in 25 office buildings in different seasons. Results obtained lead us to conclude that real coverings such as permeable, semi-permeable and impermeable types, present different behavioural patterns in indoor air conditions. Furthermore, we concluded that an absorbent structure will moderate relative humidity indoors. In this paper, we study this indoor relative humidity effect on local thermal discomfort, due to decreased respiratory cooling, and indoor ambience acceptability for the early hours of morning applying PD and Acc models [Toftum J, Jorgensen AS, Fanger PO.

    2013-01-01

    The quest towards energy conservative building design is increasingly popular in recent years, which has triggered greater interests in developing energy efficient systems for space cooling in buildings. In this work, energy efficient silver–titania HiTES (hybrid nanocomposites-based cool thermal energy storage) system combined with building A/C (air conditioning) system was experimentally investigated for summer and winter design conditions. HiNPCM (hybrid nanocomposite particles embedded PCM) used as the heat storage material has exhibited 7.3–58.4% of improved thermal conductivity than at its purest state. The complete freezing time for HiNPCM was reduced by 15% which was attributed to its improved thermophysical characteristics. Experimental results suggest that the effective energy redistribution capability of HiTES system has contributed for reduction in the chiller nominal cooling capacity by 46.3% and 39.6% respectively, under part load and on-peak load operating conditions. The HiTES A/C system achieved 27.3% and 32.5% of on-peak energy savings potential in summer and winter respectively compared to the conventional A/C system. For the same operating conditions, this system yield 8.3%, 12.2% and 7.2% and 10.2% of per day average and yearly energy conservation respectively. This system can be applied for year-round space conditioning application without sacrificing energy efficiency in buildings. - Highlights: • Energy storage is acquired by HiTES (hybrid nanocomposites-thermal storage) system. • Thermal conductivity of HiNPCM (hybrid nanocomposites-PCM) was improved by 58.4%. • Freezing time of HiNPCM was reduced by 15% that enabled improved energy efficiency. • Chiller nominal capacity was reduced by 46.3% and 39.6% in on-peak and part load respectively. • HiTES A/C system achieved appreciable energy savings in the range of 8.3–12.2%

    2018-06-01

    There is a significant disparity in roles, responsibilities, education, training, and expertise between the school nurse and building administrator. Because of this disparity, a natural chasm must be bridged to optimize student health, safety, well-being, and achievement in the classroom while meeting the individual needs of both professionals. This article constructs and presents a new school nurse-building administrator relationship model, the foundation of which is formed from the pioneering and seminal work on high-performance professional relationships and outcomes of Lewin and Drucker. The authors posit that this new model provides the framework for successful school nurse-building administrator interactions that will lead to optimal student outcomes.

  15. THE USE OF AIR LAYERS IN BUILDING ENVELOPES FOR ENERGY SAVING DURING AIR CONDITIONING

    2017-01-01

    Full Text Available Since there are no large natural energy resources in Belarus, energy savings ought to be a point of the special attention. With this regard it is important to develop modern ways of savings during the process of air conditioning inside new buildings with an air layer in the enclosure, especially in translucent ones. The system of ventilation of air layers in the enclosure of a building has been introduced in which air movement is caused by the gravitational and aerodynamic forces. It makes it possible to arrange further ventilation – a natural, forced or a hybrid one. With the purpose of increasing and streamlining natural draught the partitions are used separating the different parts of air layers. For natural ventilation with the use of gravitational forces the holes in the upper and lower parts of the partitions between adjacent air layers are applied. Natural ventilation in the holes of the partitions is regulated by movable shutters, blinds or other adjusting devices. For combined or forced air exchange between adjacent zones of air layers fans are used pumping air from the air layer zones with a higher temperature to zones of air layers with lower temperature and vice versa. When air exchange is forced, in order to intensify the infiltration of air into zones of air layers jets are laid on a hard surface. In order to cool a multi-layered enclosure of a building, where the movement of air between the air layers (that have been formed by internal partitions is being fulfilled by a natural, forced or combined mode, a part of the air or the total air processed inside the building (i.e. conditioned or non-conditioned air cooler as compared with the outside one is being sent to these strata. Combined or forced flow of the air processed inside the building into the air layers is done through the ducts associated with the output channels of the air conditioners. The internal partitions are equipped with the air valve hole.

    A series of measurements were carried out to understand the characteristics of radon and its progeny in air-conditioned office buildings. Long-term measurements of radon were made with etched track detectors. Continuous measurements of radon and its progeny concentrations were also conducted in some buildings to study their temporal variations. The results show that radon and its progeny concentrations routinely varied along with working activities. They are generally low while people are working, due to air conditioning, whereas they rise steadily after the air conditioning stops. When considering action levels not only in homes but also workplaces, attention should be paid to annual doses from the viewpoint of radiation protection. The annual dose is generally estimated with a long-term measurement of radon concentration using a passive device such as an etched track detector. Since its reading corresponds to a long-term average concentration regardless of working hours, the annual dose will be overestimated. When comparing a real dose after considering the working hours, they differ by a factor of more than 2. (author)

    The appeal and popularity of "building blocks", i.e., simple and dissociable elements of behavior and experience, persists in psychological research. We begin our assessment of this research strategy with an historical review of structuralism (as espoused by E. B. Titchener) and behaviorism (espoused by J. B. Watson and B. F. Skinner), two movements that held the assumption in their attempts to provide a systematic and unified discipline. We point out the ways in which the elementism of the two schools selected, framed, and excluded topics of study. After the historical review, we turn to contemporary literature and highlight the persistence of research into building blocks and the associated framing and exclusions in psychological research. The assumption that complex categories of human psychology can be understood in terms of their elementary components and simplest forms seems indefensible. In specific cases, therefore, reliance on the assumption requires justification. Finally, we review alternative strategies that bypass the commitment to building blocks.

    This case study investigates the effects of ventilation intervention on measured and perceived indoor air quality (IAQ) in a repaired school where occupants reported IAQ problems. Occupants’ symptoms were suspected to be related to the impurities leaked indoors through the building envelope. The study’s aim was to determine whether a positive pressure of 5–7 Pa prevents the infiltration of harmful chemical and microbiological agents from structures, thus decreasing symptoms and discomfort. Ventilation intervention was conducted in a building section comprising 12 classrooms and was completed with IAQ measurements and occupants’ questionnaires. After intervention, the concentration of total volatile organic compounds (TVOC) and fine particulate matter (PM2.5) decreased, and occupants’ negative perceptions became more moderate compared to those for other parts of the building. The indoor mycobiota differed in species composition from the outdoor mycobiota, and changed remarkably with the intervention, indicating that some species may have emanated from an indoor source before the intervention.

    Energy conscious design of school buildings, as well as deemed-to-satisfy provisions in a Performance Based Energy Code, should address the problem known as the energy efficiency - thermal comfort - indoor air quality dilemma (EE-TC-IAQ Dilemma). In warm and moderate climates, the large internal heat sources usually found in school buildings prevent achieving thermal comfort without active cooling in summer, but are not sufficient to eliminate the need for heating in winter. Commonly used air-conditioners do not improve air quality, while natural ventilation induces uncontrolled energy losses. In this study, a step by step process was used for the development of deemed-to-satisfy design solutions, which cope with the EE-TC-IAQ Dilemma, for a performance based code. A distinction is made between improving building design variables and improving ventilation schemes. Results indicate that implementation of improved ventilation schemes in an otherwise well designed energy-conscious building result in savings of 28-30% and 17-18% for northern and southern classroom orientations, respectively.

    Full Text Available Currently, urban heat island (UHI phenomenon and building energy consumptions are becoming serious. Strategies to mitigate UHI and reduce building energy consumptions are implemented worldwide. In Japan, as an effective means of mitigating UHI and saving energy of buildings, highly reflective (HR and green roofs are increasingly used. In order to evaluate the effect of roofs with high reflection and thermal insulation on the energy conservation of buildings, we investigated the roof solar reflectivity of the subject school in Osaka, in which the HR roofing sheet was installed on the roof from 2010. Thermal loads, including cooling and heating loads of the top floor of school, were calculated using the thermal load calculation software, New HASP/ACLD-β. Comparing the thermal loads after HR roofing sheet installation to previous, the annual thermal load decreased about 25 MJ/m2-year and the cooling load decreased about 112 MJ/m2-year. However, the heating load increased about 87 MJ/m2-year in winter. To minimize the annual thermal load, thermal insulation of the roof was also considered be used together with HR roofing sheet in this study. The results showed that the combination of HR roofing sheet and high thermal insulation is more effective to reduce the annual thermal load.

    Full Text Available Abstract Background Infertility is a serious problem for those who suffer. Some of the risks for infertility are preventable and the individual should therefore have knowledge of them. The purposes of this study were to investigate high-school students' knowledge about fertility, plans for family building and to compare views and knowledge between female and male students. Methods A questionnaire containing 34 items was answered by 274 students. Answers from male and female students were compared using student's t-test for normally distributed variables and Mann-Whitney U-test for non-normal distributions. The chi-square test was used to compare proportions of male and female students who answered questions on nominal and ordinal scales. Differences were considered as statistically significant at a p-value of 0.05. Results Analyses showed that 234 (85% intended to have children. Female students felt parenthood to be significantly more important than male students: p = 0.01. The mean age at which the respondents thought they would like to start to build their family was 26 (± 2.9 years. Men believed that women's fertility declined significantly later than women did: p = 0.01. Women answered that 30.7% couples were involuntarily infertile and men answered 22.5%: p = 0.01. Females thought it significantly more likely that they would consider IVF or adoption than men, p = 0.01. Men felt they were more likely to abstain from having children than women: p = 0.01. Women believed that body weight influenced fertility significantly more often than men: p = 0.01 and men believed significantly more often that smoking influenced fertility: p = 0.03. Both female and male students answered that they would like to have more knowledge about the area of fertility. Conclusions Young people plan to start their families when the woman's fertility is already in decline. Improving young people's knowledge about these issues would give them more opportunity to take

    Full Text Available The need to address climate change caused by greenhouse gas emissions attaches great importance to research aimed at using renewable energy. Geothermal energy is an interesting alternative concerning the production of energy for air conditioning of buildings (heating and cooling, through the use of geothermal heat pumps. In this work a model has been developed in order to simulate an air conditioning system with geothermal heat pump. A ground source heat pump (GSHP uses the shallow ground as a source of heat, thus taking advantage of its seasonally moderate temperatures. GSHP must be coupled with geothermal exchangers. The model leads to design optimization of geothermal heat exchangers and to verify the operation of the geothermal plant.

The finding shows that task-related performance is significantly correlated with the human perception of thermal environment that in turn is dependent on temperatures. Different combinations of thermal criteria (air velocity, clo, metabolic, etc.) can lead to similar PMV value and the PMV equation is useful to predict productivity loss that is due to the rate of change in thermal conditions. The study also highlights the issues that remain to be resolved in future research. (author)

    Full Text Available BACKGROUND: A study of the helminth infection status of primary-school children and the hygiene condition of schools in Ikenne Local Government Area of Ogun State, Nigeria was undertaken between November 2004 and February 2005 to help guide the development of a school-based health programme. METHODS AND FINDINGS: THREE PRIMARY SCHOOLS WERE RANDOMLY SELECTED: two government-owned schools (one urban and the other rural and one urban private school. No rural private schools existed to survey. A total of 257 schoolchildren aged 4-15 y, of whom 146 (56.8% were boys and 111 (43.2% were girls, took part in the survey. A child survey form, which included columns for name, age, sex, and class level, was used in concert with examination of stool samples for eggs of intestinal helminths. A school survey form was used to assess the conditions of water supply, condition of latrines, presence of soap for handwashing, and presence of garbage around the school compound. The demographic data showed that the number of schoolchildren gradually decreased as their ages increased in all three schools. The sex ratio was proportional in the urban school until primary level 3, after which the number of female pupils gradually decreased, whereas in the private school, sexes were proportionally distributed even in higher classes. The prevalence of helminth infection was 54.9% of schoolchildren in the urban government school, 63.5% in the rural government school, and 28.4% in the urban private school. Ascaris lumbricoides was the most prevalent species, followed by Trichuris trichiura, Taenia species, and hookworm in the three schools. Prevalence of infection in the government-owned schools was significantly higher than in the private school (chi(2 = 18.85, df = 2, p<0.0005. A survey of hygiene conditions in the three schools indicated that in the two government schools tapwater was unavailable, sanitation of latrines was poor, handwashing soap was unavailable, and garbage

    Skiba, Marta; Rzeszowska, Natalia

    2017-09-01

    One of the five far-reaching goals of the European Union is climate change and sustainable energy use. The first step in the implementation of this task is to reduce energy demand in buildings to a minimum by 2021, and in the case of public buildings by 2019. This article analyses the possibility of improving energy efficiency in public buildings, the relationship between particular indicators of the demand for usable energy (UE), final energy (FE) and primary energy (PE) in buildings and the impact of these indicators on the assessment of energy efficiency in public buildings, based on 5 variants of extensive thermal renovation of a school building. The analysis of the abovementioned variants confirms that the thermal renovation of merely the outer envelope of the building is insufficient and requires the use of additional energy sources, for example RES. Moreover, each indicator of energy demand in the building plays a key role in assessing the energy efficiency of the building. For this reason it is important to analyze each of them individually, as well as the dependencies between them.

    Highlights: • A generic fully air-conditioned office building with inclined walls was modeled. • Simulations were run under climatic conditions in three modern cities in China. • Reduction in cooling load can outweigh the increase in heating load for Hong Kong. • Inclined angle of 30° is appropriate for inverted pyramidal building in Hong Kong. • Building constructed with inclined walls is not encouraged in Shanghai and Beijing. - Abstract: An inverted pyramidal building is built with inclined walls instead of the traditional vertical façades. In terms of thermal performance, an inverted pyramidal building can provide a self-shading effect against the beam solar radiation, leading to a reduction in solar heat gain as well as building cooling load. On the other hand, the heating requirement of an inverted pyramidal building will be increased in winter. There is a strong dependency of building performance on the climatic condition. In this study, a generic air-conditioned office building with inclined walls set at different inclination angles was modeled using a building energy simulation program. Computer simulations were run to assess the thermal performance of the building constructed with inclined walls under different climatic conditions in three modern cities in China–Hong Kong, Shanghai and Beijing. The results reveal that for the building cases with inclined walls set at different inclination angles in subtropical Hong Kong, the saving in annual cooling load ranges from 0.6% to 10.9% and can outweigh the increase in heating load. Moreover, an inclination angle of 30° was found as a better design option for an inverted pyramidal building with symmetrical layout design under the climatic condition in Hong Kong. For the other two cities: Shanghai and Beijing, the saving in cooling load due to self-shading effect cannot offset the increased heating requirement. Design and construction of an inverted pyramidal building is not encouraged in these two

    Full Text Available Introduction: Background noise affects the listening environment inside classrooms, especially for younger children. High background noise level adversely affects not only student speech perception but also teacher vocal hygiene. The current study aimed to give an overview of the classroom listening conditions in selected government primary schools in India. Materials and Methods: Noise measurements were taken in 23 classrooms of four government primary schools in southern India, using a type 2 sound level meter. In each classroom measurements were taken in occupied and unoccupied conditions. Teacher voice level was measured in the same classrooms. In addition, the classroom acoustical conditions were observed and the reverberation time for each classroom was calculated. Results: The mean occupied noise level was 62.1 dBA and 65.6 dBC, and the mean unoccupied level was 62.2 dBA and 65 dBC. The mean unamplified teacher speech-to-noise ratio was 10.6 dBA. Both the occupied and unoccupied noise levels exceeded national and international recommended levels and the teacher speech-to-noise ratio was also found to be inadequate in most classrooms. The estimated reverberation time in all classrooms was greater than 2.6 seconds, which is almost double the duration of accepted standards. In addition, observation of classrooms revealed insufficient acoustical treatment to effectively reduce internal and external noise and minimize reverberation. Conclusion: The results of this study point out the need to improve the listening environment for children in government primary schools in India.

    Full Text Available Indoor climate affects health and productivity of the occupants in office buildings, yet in many buildings of this type indoor climate conditions are not well-controlled due to insufficient heating or cooling capacity, high swings of external or internal heat loads, improper control or operation of heating, ventilation and air conditioning (HVAC equipment, etc. However, maintenance of good indoor environmental conditions in buildings requires increased investments and possible higher energy consumption. This paper focuses on the relation between investment costs for retrofitting HVAC equipment as well as decreased energy use and improved performance of occupants in office buildings. The cost-benefit analysis implementation algorithm is presented in this paper, including energy survey of the building, estimation of occupants dissatisfied by key indoor climate indicators using questionnaire survey and measurements. Technique for Order Preference by Similarity to Ideal Solution (TOPSIS analysis is used in the proposed method for data processing. A case study of an office building is presented in order to introduce an application example of the proposed method. Results of the study verify the applicability of the proposed algorithm and TOPSIS analysis as a practical tool for office building surveys in order to maximize productivity by means of cost efficient technical building retrofitting solutions.

    2016-04-01

    The impacts of adverse events related to geological hazards are unevenly distributed among communities and groups of individuals concentrated in restricted workplaces. Their consequent safety level is the result of differential exposures to these events and of diversified levels of preparation to them. Nowadays, the exposure and coping ability as co-determinants of people's safety are of particular interest for institutions managing the schools systems. According to the disaster risk reduction experts, the geo-hydrological processes can be mitigated with knowledge and planning, physical and environmental protection measures, and response preparedness. UNISDR is promoting a global culture of safety and resilience through the integration of disaster risk reduction in school curricula. The Comprehensive School Safety (CSS) framework is intended to advance the goals of the Worldwide Initiative for Safe Schools and the Global Alliance for Disaster Risk Reduction and Resilience in the Education Sector, and to promote school safety as a priority area of post-2015 frameworks for sustainable development, risk reduction and resilience. In Italy, according the latest ministerial survey (June 2010), there are 41,902 school buildings. Their alarming condition in terms of safety for their daily occupants is reflected by 39 fatalities ascribable to structural failures in the last 21 years. In 95% of these cases victims are a sad tribute due to natural phenomena. A rigorous evaluation of the total risk of a school building, as defined by the well known risk equation (R=HxVxE), would require a complete probability density function describing the exposure to specific types of events of all the pupils and personnel in the school. In addition, the probability that the inhabitants are present in the school during an event should be estimated depending on the time of day, day of week, or month of the year, as well as on local holiday schedules. The inclusion of resilience as a component

    The purpose of this investigation was to explore the career experiences of Australian strength and conditioning coaches. Six Australian strength and conditioning coaches (mean age = 33.7 years, SD = 6.0 years) with a mean of 10.4 (SD = 4.9) years experience working with elite Olympic and professional athletes were interviewed about their experiences of career development. Each interview was transcribed verbatim and analyzed to produce key themes and subthemes relating to (a) work environments, (b) sport management practice, (c) career development processes, and (d) career building strategies. The work environments of Australian strength and conditioning coaches were found to be poor because of long working hours and irregular human resource policy and management practices of sport organizations. Because of the volatile and unpredictable nature of their working conditions, the coaches interviewed have only a short-term view of their career creating considerable stress in their lives. The coaches interviewed found it difficult to develop their careers because their only options were self-supported and self-funded professional development activities. The coaches in this study believed that more needed to be done at a policy and management level by sport organizations and their professional body to enhance the career development of strength and conditioning coaches because they play a key role in both athlete and sport organization performance. These results may help sport organizations develop policies and management practices that enhance the careers of strength and conditioning coaches and will have important practical implications for the education and development of sport professionals.

    2015-10-01

    Full Text Available This paper sets out to compare two different cooling systems that use vapor compression chillers for air conditioning environments. It was proposed to compare different operations in isolated and combined action operations. These operations are evaluated in the concepts of green buildings. A mathematical model was developed based on the principles of mass and energy conservation and complemented by various functions so as to determine the thermophysical properties and efficiencies of the compressors. The equations of the model were solved by the EES (Engineering Equation Solver program. The model evaluates the influence of the main HVAC operating parameters of the chilled water system when operating under three different configurations. The results showed that the system with a differentiated compression presents a COP equal to that of the system with screw chillers in the range  0-300 RTs, and a COP hat is on average 9% higher in the range 400-800 RTs.

    Highlights: • We examine that through-wall crack risk in cold weather is high. • It is predicted that cracking in concrete wall will not happen in hot region. • Cracking due to hydration heat can be controlled by appropriate curing condition. • Temperature differences between inner and outer face is relatively small in hot weather. - Abstract: Prediction of concrete cracking due to hydration heat in mass concrete such as reactor containment building (RCB) in nuclear power plant is a crucial issue in construction site. In this study, the numerical analysis for heat transfer and stress development is performed for the containment wall in RCB by considering the severe weather conditions. Finally, concrete cracking risk in hot and cold weather is discussed based on analysis results. In analyses considering severe weather conditions, it is found that the through-wall cracking risk in cold weather is high due to the abrupt temperature difference between inside concrete and the ambient air in cold region. In hot weather, temperature differences between inner and outer face is relatively small, and accordingly the relevant cracking risk is relatively low in contrast with cold weather

    The paper investigated the feasibility of a novel dew point evaporative cooling for air conditioning of buildings in China regions. The issues involved include analyses of China weather conditions, investigation of availability of water for dew point cooling, and assessment of cooling capacity of the system within various regions of China. It is concluded that the dew point system is suitable for most regions of China, particularly northern and west regions of China where the climate is hot and dry during the summer season. It is less suitable for Guangzhou and Shanghai where climates are hot and humid. However, an air pre-treatment process involving a silica-gel dehumidification will enable the technology to be used for these humid areas. Lower humidity results in a higher difference between the dry bulb and dew point of the air, which benefits the system in terms of enhancing its cooling performance. Tap water has adequate temperature to feed the system for cooling and its consumption rate is in the range 2.6-3 litres per kWh cooling output. The cooling output of the system ranges from 1.1 to 4.3 W per m{sup 3}/h air flow rate in China, depending on the region where the system applies. For a unit with 2 kW of cooling output, the required air volume flow rate varies with its application location and is in the range 570-1800 m{sup 3}/h. For a 50 m{sup 2} building with 60 W/m{sup 2} cooling load, if the system operates at working hours, i.e., 09:00 to 17:00 h, its daily water consumption would be in the range of 60-70 litres. Compared with mild or humid climates, the dry and hot climates need less air volume flow rate and less water. (author)

  14. Necessity and opportunity of building a mobile facility for conditioning the spent ionic resins

    International Nuclear Information System (INIS)

    Barariu, Gheorghe

    2002-01-01

    The ionic resins utilized in nuclear industry for purification of different working fluids become contaminated by important amounts of radionuclides incorporated in their structure. Thus, these resins become intermediate-level radioactive wastes, containing radioisotopes of rather long lifetimes, and so their conditioning is required to ensure binding and isolation of the radionuclides over a period long enough, until their decay. Binding the radionuclides in stable matrices and their isolation by means of engineered barriers ensures protection of environment against contamination. In the frame of Radioactive Waste Management Program related to Cernavoda NPP, optimal technologies for processing the radioactive waste generated during the NPP operation were developed and also a site for final disposal of the low and intermediate level waste was selected. The last one is a modern, ground repository with multiple engineered barriers based on the natural properties of the host geological formation. The final disposal concept implies building a conditioning facility to ensure: a super-compacting stage of the already compacted wastes; cementing the uncompactable wastes; cementing spent filters; cementing the pellets resulted from the super-compacting stage and drums with conditioned wastes in concrete modules; cementing the organic wastes; cementing the spent ionic resins by means of a mobile facility. The spent ionic resins removed from the technologic purification systems of the station are discharged by means of demineralized water and transferred, corresponding to source, to one of the 3 storage 200 m 3 basins from the basement of the CANDU 6 NPP servicing building. To avoid the danger of spent resins being cemented at basin's bottom the basins should be emptied at every 10-15 years.

    Purpose: To improve the temperature and humidity conditions for the working circumstance, prevent condensations on the wall surface and enable the reduction in the irradiation exposure to workers. Constitution: Air intake ports are provided on the side wall of a fuel storage pool or an equipment installation pool above the water level and connected by way of their exhaust ducts to the exhaust ducts of an air ventilation system. While on the other hand, air feed ducts having horizontally opened blowing ports and air exhaust ducts having horizontally opened exhaust ports above and in adjacent to the air feed ducts are provided on the side walls of the pool buildings at the height near the floor level. With this structure, fresh outdoor airs blown out horizontally from the blowing ports provided near the floor level can improve the temperature and humidity conditions of the working circumstance for the workers working on the floor. Further, an air clean up device is provided to the feed and exhaust systems for clean up the feed and exhaust airs. (Furukawa, Y.)

  16. A Novel Distributed Economic Model Predictive Control Approach for Building Air-Conditioning Systems in Microgrids

    Directory of Open Access Journals (Sweden)

    Xinan Zhang

    2018-04-01

    Full Text Available With the penetration of grid-connected renewable energy generation, microgrids are facing stability and power quality problems caused by renewable intermittency. To alleviate such problems, demand side management (DSM of responsive loads, such as building air-conditioning system (BACS, has been proposed and studied. In recent years, numerous control approaches have been published for proper management of single BACS. The majority of these approaches focus on either the control of BACS for attenuating power fluctuations in the grid or the operating cost minimization on behalf of the residents. These two control objectives are paramount for BACS control in microgrids and can be conflicting. As such, they should be considered together in control design. As individual buildings may have different owners/residents, it is natural to control different BACSs in an autonomous and self-interested manner to minimize the operational costs for the owners/residents. Unfortunately, such “selfish” operation can result in abrupt and large power fluctuations at the point of common coupling (PCC of the microgrid due to lack of coordination. Consequently, the original objective of mitigating power fluctuations generated by renewable intermittency cannot be achieved. To minimize the operating costs of individual BACSs and simultaneously ensure desirable overall power flow at PCC, this paper proposes a novel distributed control framework based on the dissipativity theory. The proposed method achieves the objective of renewable intermittency mitigation through proper coordination of distributed BACS controllers and is scalable and computationally efficient. Simulation studies are carried out to illustrate the efficacy of the proposed control framework.

The ultimate aim was to make recommendations to regional bodies so that they could make structural interventions more precisely and assertively. The study was carried out in seven educational units, in which planimetric surveys were carried out, the collection of fault symptoms, tests in some structural members and finally a general evaluation of damages that allowed identifying their durability and particular recommendations for each school building. As a result, these units of different construction ages were in a better state of conservation, when compared directly to the sample evaluated in 2006 in private multifamily buildings, which were even younger than this sample. It was recommended for all cases that they apply a programmed and technical continuous maintenance system, which goes beyond the systems of paints whose substrate is not properly prepared, resulting in a process of superficial repair and aesthetic ineffective.

    Astronomers Without Borders (AWB) organized several programs for the August 21, 2017 total solar eclipse, both before and after the event, to increase participation, build on the inspiration of the eclipse, share the eclipse experience, and prepare for the eclipse in 2024.AWB focused on preparing institutions that were least likely to receive resources despite extensive nationwide efforts. AWB distributed more than 100,000 donated glasses, to isolated schools, children's cancer hospitals, abused women’s shelters, and other institutions without access to other resource providers.AWB’s Building on the Eclipse Education Program builds on the inspiration of the eclipse for STEM education. The program uses a small, personal spectroscope kit to study sunlight in different scientific fields and includes free classroom activities that meet NGSS standards.A program to collect eclipse observing glasses for schools in developing countries for future eclipses was announced around the time of the eclipse and quickly went viral, with coverage by national and innumerable local media outlets. This effort builds on AWB’s earlier programs for schools in Africa and in South America for past eclipses. Well over one million pairs are expected, as compared to the tens of thousands AWB provided through crowdfunding for previous efforts. Nearly 1000 glasses collection centers were created spontaneously, without a public call. Factors leading to widespread and diverse public participation will be presented.A program calling for first-time eclipse observers to share their experiences addresses a major issue in encouraging people to travel to the path of totality. Expert and eclipse-enthusiast testimony often fails to convince people of the value of the experience of totality as “a few minutes of darkness.” This program will share the disconnect between expectation and experience from first-time “ordinary” observers to encourage others to travel to the path of totality for the

    Full Text Available This case study investigates the effects of ventilation intervention on measured and perceived indoor air quality (IAQ in a repaired school where occupants reported IAQ problems. Occupants’ symptoms were suspected to be related to the impurities leaked indoors through the building envelope. The study’s aim was to determine whether a positive pressure of 5–7 Pa prevents the infiltration of harmful chemical and microbiological agents from structures, thus decreasing symptoms and discomfort. Ventilation intervention was conducted in a building section comprising 12 classrooms and was completed with IAQ measurements and occupants’ questionnaires. After intervention, the concentration of total volatile organic compounds (TVOC and fine particulate matter (PM2.5 decreased, and occupants’ negative perceptions became more moderate compared to those for other parts of the building. The indoor mycobiota differed in species composition from the outdoor mycobiota, and changed remarkably with the intervention, indicating that some species may have emanated from an indoor source before the intervention.

    Full Text Available Daylighting using skylight has been shown to have a high potential in reducing electrical lighting energy, and could provide a more pleasant atmosphere of a daylit space. However, in hot climates, the main constraint of daylighting is the solar heat gain that contributes to major heat load for an air-conditioning system. If the balance between the beneficial light gain used to offset lighting energy requirement and heat gain from daylight is well considered, significant energy savings can be obtained. The main objective of the study is to evaluate the potential of daylighting for energy conservation in the tropics through theoretical analysis (simulation study and experimental observation. Lai Sue Thai Building (an existing and educational building located at Ramkhamkaeng University was selected as a case study. From analysis, use of daylight could reduce electrical energy in this building by up to 76% compared to the initial condition where fully lighting was supplied. Window orientation would also play an important role. Moreover, heat gain through windows due to daylighting can be controlled by overhangs and the appropriate Window-to-Wall ratio that would be about 30% for this building. An experimental study was also carried out to validate the results in a selected room. About 49% and 37% of Relative Root Mean Square Error (RRMSE were observed in light and heat measurements, respectively

  2. BUILDING PLURALIST ATTITUDE IN DOING ISLAMIC EDUCATION AT HIGHT SCHOOL AND MADRASAH

    2013-06-01

    Full Text Available The pluralist attitude is often associated with acknowledging and appreciating ethnic and religious differences which are, in fact, plural. The plurality of ethnicity is a natural process because no one can choose to be born into parents of a certain group. Meanwhile the plurality of religion is the result of someone’s choice of faith and is part of the human rights. A person cannot change their ethnicity but it is possible for them to change their religion. Nor can religious conversion change a person’s ethnicity, as in the case in West Kalimantan where a Christian ethnic Dayak converts to Islam to become a Malay, for example. It is why religion and ethnicity are plural, so appreciating and acknowledging the plurality as inevitability is known as a “pluralist” attitude. In Islam, especially in the instruction of Islamic education at school, or madrasah, pluralist attitude should be extended to include not only the attitude of acknowledging and appreciating ethnic and religious differences, but also the awareness of the existence of variants of the plurality in a religion, ethnicity and even in a family. Building a pluralist attitude among people with the same faith and ethnicity is often overlooked, that later led to an attitude of ambiguity, thus being friendly towards people of a different religion or ethnicity, but being hostile when dealing with fellow religious or ethnic members. The phenomenon is clearly visible in the dispute between the followers of Sunni and the Shi’ite in which the leaders are brothers. To ensure that the instruction of Islamic education is able to build a pluralist attitude on learners, we need to start building the ability of teachers to develop the curriculum, prepare the lesson plans, develop contextual learning materials and use varied learning strategies and methods.

    Researchers and policymakers agree that schools and parents must work together if they are to provide the sustenance, services, and support which children need to be successful in our increasingly complex society. (Clark, 1983; Comer, 1980, 1996; Clinton, 1995; Epstein, 1995, 1996). Unfortunately, the social and academic success of language minority students is often adversely affected by the alienation of parents from school culture and by the "deficit" view which teachers hold of language minority parents' academic and parenting skills (Boggs, 1985; Delgado-Gaitan, 1990; Heath, 1983; Lareau, 1987, 1989; Philips, 1983). This case study describes the attempts of one school site to build academic and social bridges between immigrant families from a Southeast Asian Hill Tribe, the Iu Mien, and a mainstream elementary school. This effort is facilitated by a constructivist approach to curriculum in which parents, teachers, and children create an intercultural space---a school community garden---as a context in which academic dialogue can occur. Various strategies which enable inter-cultural learning are described, including the use of students as ethnographers, of parents as expert teachers, and of teachers as cultural brokers. The study also considers the cultural conflicts and understandings which occurred when American teachers and Mien parents built a Mien field-house together: a structure which became symbolic of their blended lives. Through both a descriptive narration and interviews with various participants, the study analyzes (a) community-based curriculum development, led by practitioner reformers, as a way to enable language minority students to be academically successful within their own life worlds, as well as (b) the political and bureaucratic forces which make community-based reforms difficult to sustain. This study employs qualitative research strategies within an action-research context in which the author plays the dual role of practitioner reformer

    Divergence in the acceptability to people in different regions of naturally ventilated thermal environments raises a concern over the extent to which the ASHRAE Standard 55 may be applied as a universal criterion of thermal comfort. In this study, the ASHRAE 55 adaptive model of thermal comfort was investigated for its applicability to a hot and humid climate through a long-term field survey performed in central Taiwan among local students attending 14 elementary and high schools during September to January. Adaptive behaviors, thermal neutrality, and thermal comfort zones are explored. A probit analysis of thermal acceptability responses from students was performed in place of the conventional linear regression of thermal sensation votes against operative temperature to investigate the limits of comfort zones for 90% and 80% acceptability; the corresponding comfort zones were found to occur at 20.1-28.4°C and 17.6-30.0°C, respectively. In comparison with the yearly comfort zones recommended by the adaptive model for naturally ventilated spaces in the ASHRAE Standard 55, those observed in this study differ in the lower limit for 80% acceptability, with the observed level being 1.7°C lower than the ASHRAE-recommended value. These findings can be generalized to the population of school children, thus providing information that can supplement ASHRAE Standard 55 in evaluating the thermal performance of naturally ventilated school buildings, particularly in hot-humid areas such as Taiwan.

    This paper describes the Sofri project, a cooperation between Ceeran Ltd and The Delft University of Technology. The main objective of this project is to develop the necessary knowledge and experience to commercialize solar-assisted air conditioning and dehumidification systems in the Dutch Caribbean. The project is motivated by the present needs of the Dutch Caribbean for renewable energy sources and the fact that the Caribbean has a high and uniform insolation throughout the year. Furthermore, hotels and offices in this area use more than 40% of their energy for air-conditioning purposes. Therefore solar-assisted air conditioning systems are a logic approach in reducing the energy demand and to lower the peak electricity reducing the energy demands for the local power station. Ceeran Ltd has the objective to reach full commercialization of the proposed technologies in the Dutch Caribbean. The research is concentrated on liquid absorption machines and solar collection systems such as flat plates with selective surfaces, heat pipe evacuated tubes flat plate collectors, and Compound Parabolic Concentrators. The first demonstration unit is planned to be installed in an office building in Curacao. The installation consists of a 35 kW LiBr/H{sub 2}O absorption machine driven by 100 m{sup 2} flat pate collectors with a gas backup system. The system will provide comfort air-conditioning for this these type of office buildings during daytime.

    We investigated the symbiont-bearing benthic foraminifer Palaeonummulites venosus to determine the chamber building rate (CBR), test diameter increase rate (DIR), reproduction time and longevity using the `natural laboratory' approach. This is based on the decomposition of monthly obtained frequency distributions of chamber number and test diameter into normally distributed components. Test measurements were taken using MicroCT. The shift of the mean and standard deviation of component parameters during the 15-month investigation period was used to calculate Michaelis-Menten functions applied to estimate the averaged CBR and DIR under natural conditions. The individual dates of birth were estimated using the inverse averaged CBR and the inverse DIR fitted by the individual chamber number or the individual test diameter at the sampling date. Distributions of frequencies and densities (i.e., frequency divided by sediment weight) based on both CBR and DIR revealed continuous reproduction throughout the year with two peaks, a stronger one in June determined as the onset of the summer generation (generation 1) and a weaker one in November determined as the onset of the winter generation (generation 2). This reproduction scheme explains the presence of small and large specimens in the same sample. Longevity, calculated as the maximum difference in days between the individual's birth date and the sampling date, is approximately 1.5 yr, an estimation obtained by using both CBR and DIR.

    Full Text Available Solar radiation is the main source of thermal energy for almost all the processes developing in the atmosphere, hydrosphere, and biosphere. The total duration of sunshine in Tajikistan ranges from 2100 to 3170 hours per year. Solar collectors can be mounted on the roof of a house after its renovation and modernization. One square meter of surface area in Central Asia accounts for up to 1600 kW/h of solar energy gain, whilst the average gain is 1200 kW/h. Active solar thermal systems are able to collect both low- and high-temperature heat. Active systems require the use of special engineering equipment for the collection, storage, conversion and distribution of heat, while a low-grade system is based on the principle of using a flat solar collector. The collector is connected to the storage tank for storing the heated water, gas, etc. The water temperature is in the range 50-60 °C. For summer air conditioning in hot climates, absorption-based solar installations with open evaporating solution are recommended. The UltraSolar PRO system offers an opportunity to make a home independent of traditional electricity. Combining Schneider Electric power generation and innovative energy storage technology results in an independent power supply. Traditional power supply systems can be short-lived since they store energy in lead-acid batteries which have a negligible lifetime. Lead-acid batteries operate in a constant charge-discharge mode, require specific conditions for best performance and can fail suddenly. Sudden failure of lead acid batteries, especially in winter in the northern part of Tajikistan, completely disables the heating system of a building. Instead, it is recommended to use industrial lithium-ion batteries, which have a significantly longer life and reliability compared to lead-acid type. UltraSolar PRO are ideal and provide a complete package, low noise and compact lithium-ion power supply.

    While there are plenty of anecdotal experiences of overcooled buildings in summer, evidence from field studies suggests that there is indeed an issue of overcooling in tropical buildings. The findings suggest that overcooled buildings are not a consequence of occupant preference but more like an outcome of the HVAC system design and operation. Occupants' adaptation in overcooled indoor environments through additional clothing cannot be regarded as an effective mitigating strategy for cold thermal discomfort. In the last two decades or so, several field studies and field environmental chamber studies in the tropics provided evidence for occupants' preference for a warmer temperature with adaptation methods such as elevated air speeds. It is important to bear in mind that indoor humidity levels are not compromised as they could have an impact on the inhaled air condition that could eventually affect perceived air quality. This review article has attempted to track significant developments in our understanding of the thermal comfort issues in air-conditioned office and educational buildings in hot and humid climates in the last 25 years, primarily on occupant preference for thermal comfort in such climates. The issue of overcooled buildings, by design intent or otherwise, is discussed in some detail. Finally, the article has explored some viable adaptive thermal comfort options that show considerable promise for not only improving thermal comfort in tropical buildings but are also energy efficient and could be seen as sustainable solutions. © 2015 John Wiley & Sons A/S.

    Children with chronic health conditions may perform poorer at school. Associations may be confounded by numerous social factors. We aimed to estimate the effects of a chronic health condition on overall school performance in first graders with an emphasis on rigorous adjustment for potential confounders. A population-based cohort study was performed in the area of Mainz-Bingen (Germany). In 2015 all preschoolers were approached and the presence of a chronic health condition was assessed by parental questionnaires and preschool health examination data. The identification of a chronic health condition was based on special health care needs and presence of a doctor's diagnosis out of 24 school-relevant diseases. At the end of the first school year, overall school performance was assessed by teachers and rated on a 5-item scale ranging from -10 to +10. Of 3683 children approached, 2003 were enrolled. Overall school performance was available for 1462 children (51% boys). Of these, 52% suffered from a chronic health condition. Compared to children without a chronic health condition, children with special health care needs (15%) performed worse at school (adjusted mean difference: -0.95, 95% CI: [-1.55; -0.35], P = 0.002). Children with a doctor's diagnosis but without special health care needs (37%) did not perform worse at school. The effect was further analysed considering the extent of special health care needed. Chronic health conditions affect overall school performance early in primary school. To identify academically at-risk children, a chronic health condition identification based on special health care needs may be used.

    Air quality in Dutch school buildings often very poor. Mechanical ventilation systems are installed to improve the air quality. In practice some mechanical ventilation, especially local systems with a fan in or nearby the classroom lead to unacceptable noise levels. This can result in the ventilation system being turned off and thus less air quality. Therefore, a low noise level should be an integral part of the design of the ventilation system. [Dutch] Het binnenklimaat in veel scholen is ronduit slecht, in meer dan 80% van de scholen wordt onvoldoende geventileerd, is er sprake van tocht of is het in de zomer te warm. De in 2009 verschenen ISSO publicatie 89 formuleert eisen en geeft oplossingen om tot verbetering te komen. De praktijk leert echter dat een deel van de voorgestelde mechanische ventilatiesystemen overmatige geluidsniveaus en geluidhinder veroorzaken.

    2018-02-01

    Full Text Available This paper presents experimental results from a typical school building in Athens, equipped partly with a green roof system (GRS. Environmental monitoring took place in six classrooms located both under the concrete roof and the GRS sectors as well as in the immediate external environment during the warm and cold periods of a school year. Daily measurements of pollutants CO2, TVOCs (Total Volatile Organic Compound, PM1, PM2.5, and PM10 were performed in selected classes. Moreover, indoor ambient temperature (T and relative humidity (RH measurements were implemented in order to estimate the absolute humidity (AH and assess the indoor environmental conditions. The results highlight that during summer, the GRS reduces temperature in a classroom on the top floor by about 2.8 °C, in comparison with the respective classroom under the concrete roof and that AH remained relatively stable for both classrooms. Amid winter, a reverse behavior occurs only for temperature. Moreover, air exchange rates (AER were calculated by using the CO2 decay method for all of the classrooms. The results demonstrated insufficient ventilation for all experimental sights. Finally, concentrations of PM1, PM2.5 and PM10, were found to be relatively decreased, with average values of 0.79, 3.39, and 27.80 μg m−3. Levels of CO2 and TVOCs were elevated during class hours ranging from 469 to 779 ppm and from 6.63 ppm to 13.33 ppm, respectively, but generally within the respective limits of exposure. The examination of the indoor/outdoor (I/O ratio of air pollutants, demonstrated that the outdoor meteorology affects only PM1 and PM2.5, as PM10 and TVOCs are strongly affected by internal sources and the activities of pupils.

      High-intensity sport training at the youth level has led to increased concern for overuse conditions. Few researchers have examined overuse conditions in youth sports.   To examine the rates, risks, and distributions of overuse conditions between youth and high school football players.   Descriptive epidemiologic study.   Youth and high school football teams.   The Youth Football Safety Study (YFSS) investigated youth football athletes from age 5 to 14 years. The National Athletic Treatment, Injury and Outcomes Network (NATION) focused on high school football athletes 14 to 18 years old. The YFSS data consisted of 210 team-seasons, and the NATION data consisted of 138 team-seasons.   Athletic trainers collected football injury and exposure data during the 2012 and 2013 seasons. Injury rates, risks, and distributions were calculated, with injury rate ratios, risk ratios, and injury proportion ratios with 95% confidence intervals (CIs) comparing youth and high school football players.   The YFSS reported 1488 injuries, of which 53 (3.6%) were overuse conditions. The NATION reported 12 013 injuries, of which 339 (2.8%) were overuse conditions. The overuse condition rate did not differ between high school and youth football (3.93 versus 3.72/10 000 athlete-exposures; injury rate ratio = 1.06; 95% CI = 0.79, 1.41). However, the 1-season risk of overuse condition was higher in high school than in youth football players (2.66% versus 1.05%; risk ratio = 2.53; 95% CI = 1.84, 3.47). Compared with high school football players, youth football players had greater proportions of overuse conditions that were nontime loss (ie, football players. However, differences existed between the 2 levels of competition. Although additional research on the incidence of overuse conditions across all youth and high school sports is needed, these findings may highlight the need for programming that is specific to competition level.

    Full Text Available Introduction: One of the factors influencing on indoor air quality of the buildings is performance of HVAC (heating, ventilation, and air conditioning systems. These systems supply clean and odorless air, with temperature, humidity, and air velocity within comfort ranges for the residents. The aim of this study was to evaluate performance HVAC system in an administrative building in Tehran. .Material and Method: A questionnaire, developed in their research was used to assess the building occupants’ perception about the performance of HVAC system. To evaluate the performance of HVAC systems, air velocities were measured in the diffusers using a thermal anemometer. Moreover, CO2 concentration, air temperature and relative humidity were measured in the whole floors of the building. Air distribution inside the building was evaluated using smoke test. .Results: Most of the studied people complained about the direction of airflow, thermal conditions and cigarette odor. The highest level of carbon dioxide was measured at 930 ppm inside the restaurant. The maximum and minimum air temperatures and relative humidity were measured 28.3-13.8° C and 28.4-23% respectively. Smoke test showed that the air distribution/direction wasn’t suitable in one third of air diffusers. .Conclusion: Improper air distribution / direction was the main problem with the studied HVAC system which could be corrected by adjusting and balancing of the system.

    In this paper authors point out that overheating in buildings during summer season is a major problem in moderate and cold climates, not only in warm climate zones. Mostly caused by solar heat gains, especially in buildings with large glazed areas overheating is a common problem in recently constructed low-energy buildings. At the same time, comfort demands are increasing. While heating loads can be decreased by improving the insulation of the building envelope, cooling loads are also affecting total energy demand. Passive cooling solutions allow reduction of heat gains, and thus reducing the cooling loads. There is a significant night cooling potential with low temperatures at night during summer in moderate and cold climates. Night cooling is based on cooling of buildings thermal mass during the night and heat accumulation during the day. This approach allows to provide thermal comfort, reducing cooling loads during the day. Authors investigate thermal comfort requirements and causes for discomfort. Passive cooling methods are described. The simulation modeling is carried out to analyze impact of constructions and building orientation on energy consumption for cooling using the IDA-ICE software. Main criteria for simulation analysis are energy consumption for cooling and thermal comfort.

    This article is the result of a study on how to close the gap between architects and building service consultants. Closure of this gap is necessary in order to be able to create both a better indoor climate and an interesting architectural environment. For schools with a natural air intake it is particularly necessary to check for some basic physical principles of draught prevention at an early stage of the design or commissioning process. Air supply designs for the most common architectural problems should be easily available. Most of the presented design options have been evaluated with measurements and CFD simulations. For schools with a natural air exhaust (overpressure system) the results of an on-site test are presented. This system can be applied even in existing schools with single glass windows or protected facades. [Dutch] Dit artikel is het resultaat van een onderzoek naar het dichten van de 'kloof' tussen architecten en deskundigen op het gebied van installaties. Het dichten van deze kloof is noodzakelijk om het mogelijk te maken om zowel een beter binnenklimaat als een interessante architectonische omgeving te creeren. Vooral voor scholen met een natuurlijke luchttoevoer dient in een vroeg stadium van het ontwerp- of aanbestedingsproces een aantal fysische basisprincipes van tochtpreventie te worden gecontroleerd. Voor de meest voorkomende architectonische problemen zouden ontwerpen voor de luchttoevoer eenvoudig toegankelijk moeten zijn. Het grootste gedeelte van de voorgestelde ontwerpmogelijkheden is beoordeeld aan de hand van metingen en CFD-simulaties. Voor scholen met een natuurlijke luchtafvoer (overdruksysteem) worden de resultaten gepresenteerd van een test die op locatie is uitgevoerd. Dit systeem kan zelfs worden toegepast in bestaande scholen met enkel beglaasde ramen en een monumentale gevel.

    Analyses were conducted for the reactor building to determine the dynamic responses of the coupled system, soil and structure and the forces in the characteristic structural members. This report summarizes the results of structural dynamic analyses derived for soft and hard soil conditions by the modal time history method using substructure models as well as (for soft soil conditions) in the frequency domain using complex (coupled) models of the soil and the structure. The mathematical model of the reactor building is represented as a lumped mass beam model. The capabilities of the soil were represented by means of global frequency independent springs and dampers (substructure models) or by an appropriate final element model. The results of the above-mentioned analysis presented in this report comprise in particular the maximum values of accelerations, displacements and internal forces as well as the acceleration response spectra for the relevant building regions. The time domain (modal time history) calculations were performed for real soil conditions which corresponds to the site Kozloduy (soft) and Temelin (hard). As seismic input data the corresponding free-field data here been used. The dynamic response obtained for the soft-soil conditions using both type of (substructure and complex) models were compared and demonstrated in one plot. Similar comparison were performed for the results obtained for soft and hard soil conditions

    Both high and low indoor relative humidity (RH) directly impact Indoor Air Quality (IAQ), an important school health concern. Prior school studies reported a high prevalence of mold, roaches, and water damage; however, few examined associations between modifiable classroom factors and RH, a quantitative indicator of dampness. We recorded RH longitudinally in 134 North Carolina classrooms (n = 9066 classroom-days) to quantify the relationships between modifiable classroom factors and average daily RH below, within, or above levels recommended to improve school IAQ (30-50% or 30-60% RH). The odds of having high RH (>60%) were 5.8 [95% Confidence Interval (CI): 2.9, 11.3] times higher in classrooms with annual compared to quarterly heating, ventilating, and air-conditioning (HVAC) system maintenance and 2.5 (95% CI: 1.5, 4.2) times higher in classrooms with HVAC economizers compared to those without economizers. Classrooms with direct-expansion split systems compared to chilled water systems had 2.7 (95% CI: 1.7, 4.4) times higher odds of low RH (60%) of those without setbacks. This research suggests actionable decision points for school design and maintenance to prevent high or low classroom RH. This study combines longitudinal measurements of classroom relative humidity with school inspection data from several schools to describe the problem of relative humidity control in schools. Our findings on how maintenance and mechanical factors affect classroom humidity provide suggestions on building operations policies and heating, ventilating, and air-conditioning (HVAC) design considerations that may improve classroom relative humidity control. © 2014 John Wiley & Sons A/S.

    Highlights: • A simulation model of a solar driven absorption chiller is developed in detail. • Three control strategies were proposed in the solar loop of the plant. • Series and parallel auxiliary heater arrangements were investigated. • The results showed the auxiliary-heater in parallel outperformed the series one. • Solar fraction can be increased by 20% by implementing the proposed configuration. - Abstract: Solar-assisted cooling technology has enormous potential for air-conditioning applications since both solar energy supply and cooling energy demand are well correlated. Unfortunately, market uptake of solar cooling technologies has been slow due to the high capital cost and limited design/operational experience. In the present work, different designs and operational modes for solar heating and cooling (SHC) absorption chiller systems are investigated and compared in order to identify the preferred design strategies for these systems. Three control scenarios are proposed for the solar collector loop. The first uses a constant flow pump, while the second and third control schemes employ a variable speed pump, where the solar collector (SC) set-point temperature could be either fixed or adjusted to the required demand. Series and parallel arrangements, between the auxiliary heater and the storage tank, have been examined in detail from an energy efficiency perspective. A simulation model for different system layouts is developed in the transient system simulation environment (TRNSYS, Version 17). Simulation results revealed that the total solar fraction of the plant is increased by up to 11% when a variable speed solar loop pump is used to achieve a collector set-point temperature adjusted according to the building load demand. Another significant finding of this study is that a parallel configuration for the auxiliary heater out-performs a conventional series configuration. The yearly performance of an auxiliary heater in parallel with the storage

    2016-03-01

    Full Text Available This paper describes a series of field studies and simulation analysis to improve the thermal performance of school buildings in the city of Tehran in Iran during warm season. The field studies used on-site measurement and questionnaire-based survey in the warm spring season in a typical female secondary school building. The on-site monitoring assessed the indoor air temperature and humidity levels of six classrooms while the occupants completed questionnaires covering their thermal sensations and thermal preferences. Moreover, thermal simulation analysis was also carried out to evaluate and improve the thermal performance of the classrooms based on the students’ thermal requirements and passive design strategies. In this study, the environmental design guidelines for female secondary school buildings were introduced for the hot and dry climate of Tehran, using passive design strategies. The study shows that the application of passive design strategies including south and south-east orientation, 10cm thermal insulation in wall and 5cm in the roof, and the combination of 30cm side fins and overhangs as a solar shading devices, as well as all-day ventilation strategy and the use of thermal mass materials with 25cm-30cm thickness, has considerable impact on indoor air temperatures in warm season in Tehran and keeps the indoor environment in an acceptable thermal condition. The results of the field studies also indicated that most of the occupants found their thermal environment not to be comfortable and the simulation results showed that passive design techniques had a significant influence on the indoor air temperature and can keep it in an acceptable range based on the female students’ thermal requirement. Therefore, in order to enhance the indoor environment and to increase the learning performance of the students, it is necessary to use the appropriate passive design strategies, which also reduce the need for mechanical systems and

    An attempt was made to develop multiple regression models for office buildings in the five major climates in China - severe cold, cold, hot summer and cold winter, mild, and hot summer and warm winter. A total of 12 key building design variables were identified through parametric and sensitivity analysis, and considered as inputs in the regression models. The coefficient of determination R 2 varies from 0.89 in Harbin to 0.97 in Kunming, indicating that 89-97% of the variations in annual building energy use can be explained by the changes in the 12 parameters. A pseudo-random number generator based on three simple multiplicative congruential generators was employed to generate random designs for evaluation of the regression models. The difference between regression-predicted and DOE-simulated annual building energy use are largely within 10%. It is envisaged that the regression models developed can be used to estimate the likely energy savings/penalty during the initial design stage when different building schemes and design concepts are being considered.

    The commercial sector offers strong potential for solar photovoltaics (PV) owing to abundant available roof space suitable for PV and the opportunity to offset the sector's substantial retail electricity purchases. This report evaluated the breakeven price of PV for 15 different building types and various financing options by calculating electricity savings based on detailed rate structures for most U.S. utility territories (representing approximately two thirds of U.S. commercial customers). We find that at current capital costs, an estimated 1/3 of U.S. commercial customers break even in the cash scenario and approximately 2/3 break even in the loan scenario. Variation in retail rates is a stronger driver of breakeven prices than is variation in building load or solar generation profiles. At the building level, variation in the average breakeven price is largely driven by the ability for a PV system to reduce demand charges.

    Full Text Available The aim of this paper is devoted to the coupling of ventilation systems with buildings with low energy performances under a specific Saharan climate. In the second part, the objective is to diagnose and quantify energy consumptions due to the ventilation of a real residential building in Ghardaia site. As result, ventilation system can bring a positive support to the thermos-aeraulic comfort by controlling the mass flow rate of the air entering to the heated or/and cooled building zone. Heat losses due to the ventilation system represent 4.75% of the total losses; the provided heat exchange in this case requires an additional consumption of around 6.6058% of the total energy needs.

    The improvement of energy efficiency is the key issue after the energy performance of buildings directive came into the force in European Union countries. The city of Kuopio participate a project, in which different tools will be used, generated and tested to improve the energy efficiency of public buildings. In this project there are 2 schools, the other consuming much more heating energy than the other same type of school. In this paper the results of the thermography in normal conditions and under 50 Pa pressure drop will be presented; as well as the results of remote controlled air tightness test of the buildings. Thermography combined with air tightness test showed clearly the reasons of specific consumption differences of heating energy - also in the other hand, the measurements showed the problems in the performance of ventilation system. Thermography, air tightness test and other supporting measurements can be used together to solve energy loss problems - if these measurements will be carried out by proper way.

    Full Text Available The change in the conditions of the person's life activity and its innovative mentality intensified the problems of personal and professional self-determination. The senior school age is a period of primary, ambivalent options. At this age, the foundations of the moral attitude to different kinds of work are laid, the formation of a system of personal values that determine the selectivity of the attitude of high school students to various professions. The purpose of the study was to study the socio-pedagogical conditions for the vocational guidance of high school students. The object of research is the professional orientation of high school students. The subject of the study is the design of the socio-pedagogical conditions for the vocational guidance of high school students. The article analyzes the following social and pedagogical conditions for the vocational guidance of high school students: the development of individual abilities of schoolchildren, the expansion of differentiated education in accordance with their inclinations and educational needs, the development of a network of specialized classes with in-depth study of various subjects, ensuring the level of secondary education meets the requirements of scientific and technological progress. The authors emphasize that vocational guidance is one of the key functions of a basic school in modern conditions. It is the activities of vocational guidance that contribute to the adequate professional choice of schoolchildren, which gives them further success in life, and the labor market - specialists of the required quality and in the required quantity. Consequently, the effectiveness of this work requires regular evaluation through interviews with high-school students aimed at identifying their vocational and educational orientations and assessing the quality of career counseling services. Such studies are necessary to improve the quality of vocational guidance work carried out by schools.

    Full Text Available Applications of latent transition analysis (LTA have emerged since the early 1990s, with numerous scientific findings being published in many areas, including social and behavioral sciences, education, and public health. Although LTA is effective as a statistical analytic tool for a person-centered model using longitudinal data, model building in LTA has often been subjective and confusing for applied researchers. To fill this gap in the literature, we review the components of LTA, recommend a framework of fitting LTA, and summarize what acceptable model evaluation tools should be used in practice. The proposed framework of fitting LTA consists of six steps depicted in Figure 1 from step 0 (exploring data to step 5 (fitting distal variables. We also illustrate the framework of fitting LTA with data on concerns about school bullying from a sample of 1,180 students ranging from 5th to 9th grade (mean age = 12.2 years, SD = 1.29 years at Time 1 over three semesters.

    Full Text Available With the ever-increasing population and global economy, the dependency on usage of non-renewable resources of energy is cumulating in direct proportion. Nevertheless, the non-renewable potential of these resources is certainly a leading worldwide issue, and one, which has gained substantial international interest over the past decades. Large and attractive opportunities exist to reduce building's energy use at lower costs and higher returns than other sectors. At the same time, substantial investments will be required to achieve this target as outlined by the Paris Agreement. These will require the combination of social, economic and environmental actions, including building energy codes, investment subsidies, labelling and reporting mechanisms, increased and trained workforce capacity, and evolving energy-efficient designs and HVAC technologies.

    EnergyPlus is the DOE's newest building energy simulation engine. It was developed specifically to support the design of low energy building systems. This project focused on developing new low energy building simulation models for EnergyPlus, verifying and validating new and existing EnergyPlus models and transferring the new technology to the private sector. The project focused primarily on geothermal and radiant technologies, which are related by the fact that both are based on hydronic system design. As a result of this project eight peer reviewed journal and conference papers were added to the archival literature and five technical reports were published as M.S. theses and are available in the archival literature. In addition, several reports, including a trombe wall validation report were written for web publication. Thirteen new or significantly enhanced modules were added to the EnergyPlus source code and forty-two new or significantly enhanced sections were added to the EnergyPlus documentation as a result of this work. A low energy design guide was also developed as a pedagogical tool and is available for web publication. Finally several tools including a hybrid ground source heat pump optimization program and a geothermal heat pump parameter estimation tool were developed for research and design and are available for web publication.

    2017-01-01

    Highlights: • Experimental investigation of building insulation materials in UAE from 2012–2014. • Four same calorimeters with different south walls were built in open air laboratory. • Heat flux was reduced by 22–75% in steady state analysis during summer by insulation. • Hence, energy consumption for cooling was reduced by an average 7.6–25.3%. • Heat flow was steady in free floating analysis in winter through insulated walls. - Abstract: It is known that enhancement of building energy efficiency can help in reducing energy consumption. The use of the solar insulating materials are the most efficient and cost effective passive methods for reducing the cooling requirements of the buildings. Apart from theoretical studies, no detailed experimental studies were performed in the UAE on energy savings by using solar insulation materials on buildings. Four (3 m × 3 m × 3 m) solar calorimeters were built in RAK, UAE in order to perform an open air outdoor test for energy savings obtained with solar insulating materials. The design is aimed to determine the heat flux reduction and the energy savings achieved with and without different solar insulating materials, mounted at the south wall of solar calorimeters with similar indoor and ambient conditions. Experimental results are discussed to evaluate the thermal performance during high temperature conditions in summer’s period when cooling demand of the building is at its peak and also in winters when there is no cooling demand. The test is from 2012 to 2014. The controlled-temperature experimental study at a set point of 24 °C showed that if the standard building material, i.e. solid concrete, is retrofitted with polyisocyanurate (PIR) and reflective coatings or completely replaced with energy-efficient dry insulation material walls such as exterior insulation finishing system (EIFS), energy savings up to an average of 7.6–25.3% can be achieved. This is due to the reduction of heat flux by an

    This study examined the underlying processes and conditions that contribute to the school adjustment of shy children in Turkey, where children's interpersonal relationships in social settings and academic achievement are highly emphasized. First, we examined the unique mediating roles of children's feelings of social anxiety, depressive symptoms, and loneliness in the associations between shyness and indices of school outcomes (academic achievement and school liking/avoidance). Second, we explored the moderating role of children's peer acceptance in these associations. Fourth- and fifth-grade children (N = 599; M age  = 10.11 years, SD = 0.65; 48% girls) provided information on shyness, social anxiety, depressive symptoms, loneliness, and school liking/avoidance. Head teachers in each classroom reported on students' academic performance. The peer nomination method was used to assess children's peer relationships. Results revealed that when children displayed shy behaviours, they reported more depressive symptoms that were, in turn, associated with poorer academic performance, less school liking, and higher school avoidance. Moreover, shyness negatively predicted school liking at low levels of peer acceptance, suggesting that difficulties in peer relationships increased shy children's risk of school dissatisfaction. Overall, our findings support the importance of the interpersonal relationship context for children's adjustment within the Turkish cultural context. Statement of contribution What is already known on this subject? Shy children have difficulties initiating and maintaining social interactions, which put them at risk for a wide range of socio-emotional difficulties. Shy children have poor academic performance and experience school adjustment difficulties in North America. What does this study add? Shyness is an important risk factor for poorer academic performance and adjustment among children in Turkey. The association between shyness and

    Although innovations in space education were introduced in many developing countries with good intentions, too many changes and challenges in the existing system have often penalized those who needed them the most. Consequently, the students and teachers in the underprivileged schools face isolation, neglect and coupled with inadequate pedagogic attention, poor infrastructure and insufficient resources, inadvertently suffer. Surprisingly, these deprived school students possess cognitive capabilities of comprehending nature. One of the most compelling situations in Indian school education is that the syllabus is often modified haphazardly without the necessary groundwork and infrastructure to implement it. Apparently, there has neither been teaching nor learning on applied knowledge. Despite the growth in communication and technology applications in space education, inequalities continue to exist in developing countries. In our present society many crucial services are provided by space and it becomes imperative that students have a comprehensive knowledge of space and space based technologies. To realize these objectives, we have adopted a comprehensive and holistic capacity building mechanism which incorporates differentiated instructional strategy on teaching space education in underprivileged schools. Because differentiation and scaffolding techniques yield similar instructional goals, we have blended together both the approaches to the point of being indistinguishable and this proved successful. Initiation was done through the setting up of an Astronomy Club in a backward area in Hyderabad and necessary infrastructure was provided by one of the authors. A state of the art audio-visual room with LCD Projector for ICT mode of presentations of various astronomy and space topics, having a seating capacity of 50 students is in place.

    The unique geographical location of Hainan makes its climate characteristics different from inland areas in China. The thermal comfort of Hainan also owes its uniqueness to its tropical island climate. In the past decades, there have been very few studies on thermal comfort of the residents in tropical island areas in China. A thermal environment test for different types of buildings in Hainan and a thermal comfort field investigation of 1944 subjects were conducted over a period of about two months. The results of the survey data show that a high humidity environment did not have a significant impact on human comfort. The neutral temperature for the residents in tropical island areas was 26.1 °C, and the acceptable temperature range of thermal comfort was from 23.1 °C to 29.1 °C. Residents living in tropical island areas showed higher heat resistance capacity, but lower cold tolerance than predicted. The neutral temperature for females (26.3 °C) was higher than for males (25.8 °C). Additionally, females were more sensitive to air temperature than males. The research conclusions can play a guiding role in the thermal environment design of green buildings in Hainan Province. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Mandin, C; Derbez, M; Kirchner, S

    2012-07-01

    This review provides a global overview of indoor air quality issues in schools, office buildings and recreational settings. It presents the most recent scientific publications and the on-going work conducted in France in the frame of the indoor air quality Observatory. Monitoring campaigns on indoor air quality in schools have been carried out in the recent years in Europe. However, few studies have specifically addressed the role of exposure in these buildings on children's health. Indoor air quality in office buildings has been little studied so far. However, some specificities, such as emissions from electronic devices, frequent cleaning, impossibility to open windows in high-rise buildings, for example, should be examined and their role on the health and comfort studied. Finally, even if the time spent in recreational settings is short, the quality of indoor air should also be considered because of specific pollution. This is the case of indoor swimming pools (exposure to chlorination byproducts) and ice-rinks (exposure to exhaust from machines used to smooth the ice). Copyright © 2012 Elsevier Masson SAS.

    The present state of information communication technology makes it possible to devise and run computer-based e-laboratories accessible to any user with a connection to the Internet, equipped with very simple technical means and making full use of web services. Thus, the way is open for a new strategy of physics education with strongly global features, based on experiment and experimentation. We name this strategy integrated e-learning, and remote experiments across the Internet are the foundation for this strategy. We present both pedagogical and technical reasoning for the remote experiments and outline a simple system based on a server-client approach, and on web services and Java applets. We give here an outline of the prospective remote laboratory system with data transfer using the Internet School Experimental System (ISES) as hardware and ISES WEB Control kit as software. This approach enables the simple construction of remote experiments without building any hardware and virtually no programming, using a paste and copy approach with typical prebuilt blocks such as a camera view, controls, graphs, displays, etc. We have set up and operate at present seven experiments, running round the clock, with more than 12 000 connections since 2005. The experiments are widely used in practical teaching of both university and secondary level physics. The recording of the detailed steps the experimentor takes during the measurement enables detailed study of the psychological aspects of running the experiments. The system is ready for a network of universities to start covering the basic set of physics experiments. In conclusion we summarize the results achieved and experiences of using remote experiments built on the ISES hardware system

    We investigated bacterial and fungal concentrations on cooling coils of commercial AC units and quantified associations between microbial loads and AC unit or building operational parameters. A field campaign was conducted to sample 25 AC units in the humid, subtropical climate of Southern CT, USA and 15 AC units in the hot-summer Mediterranean climate of Sacramento, CA, USA. Median concentrations (with interquartile range) of bacteria and fungi on the cooling coils were 1.2 × 10 7 (5.1 × 10 6 -3.9 × 10 7 ) cells/m 2 and 7.6 × 10 5 (5.6 × 10 4 -4.4 × 10 6 ) spore equivalents (SE)/m 2 , respectively. Concentrations varied among units with median unit concentrations ranging three orders of magnitude for bacteria and seven orders of magnitude for fungi. Controlled comparisons and multivariable regressions indicate that dominant factors associated with AC coil loading include the nominal efficiency of upstream filters (P = .008 for bacteria and P < .001 for fungi) and coil moisture, which was reflected in fungal loading differences between top and bottom halves of the AC coils in Southern CT (P = .05) and the dew points of the two climates considered (P = .04). Environmental and building characteristics explained 42% (P < .001) of bacterial concentration variability and 66% (P < .001) of fungal concentration variability among samples. © 2018 John Wiley & Sons A/S.

    2017-11-01

    The common system used for thermal regulation in mosques of United Arab Emirates (UAE) is the heating, ventilating and air-conditioning (HVAC) system. This system increases demands on energy consumption and increases CO2 emission. A passive design approach is one of the measures to reduce these problems. This study involved an analytical examination of building forms, followed by testing the impact of these forms on its thermal performance and indoor thermal comfort. The tests were conducted using energy simulations software packages. Passive parameters such as shading devices, thermal insulation and natural ventilation were applied in six cases, including the baseline case within each form. The obtained results showed a significant effect of mosque forms as well as passive design techniques on the thermal comfort within the structures. The findings confirmed that the use of passive design alone would not help achieve thermal comfort, but reduce the annual energy consumption by10%. By integrating a hybrid air-conditioning system as another supporting approach, the annual energy consumption could be reduced by 67.5%, which allows for the designing of a much smaller HVAC system.

  17. A strategy for prioritising interactive measures for enhancing energy efficiency of air-conditioned buildings

    International Nuclear Information System (INIS)

    Lee, W.L.; Yik, F.W.H.; Jones, P.

    2003-01-01

    Within a given budget, selection of the optimal set of measures for enhancing the energy efficiency of a building is often based on the relative order of the feasible measures, prioritised according to either the life cycle cost saving or the economic benefit-cost ratio of the measures. A sensitivity analysis shows that, compared to the life cycle cost analysis, the benefit-cost ratio analysis is less susceptible to the influence of uncertainties in the estimates of the present value of the life cycle energy saving and cost. Where interactive measures are involved, the effects of some are dependent on the co-existence of other measures. The prioritisation determined according to the benefit-cost ratios of individual measures, each taken in the absence of all the others, can lead to the choice of a range of measures that is below optimal. Selection of the optimal set of energy efficiency enhancement measures requires a multistep approach, which is exemplified by the case study described in the paper

    The objective of this work is to develop a fuzzy controller for naturally ventilated buildings. Approximate reasoning has proven to be in many cases more successful control strategy than classically designed controlled scheme. In this paper the process of designing a supervisory control to provide thermal comfort and adequate air distribution inside a single-sided naturally ventilated test room is described. The controller is based on fuzzy logic reasoning and sets of linguistic rules in forms of IF-THEN rules are used. The inputs to the controller are the outside wind velocity, direction, outside and inside temperatures. The output is the position of the opening. A selection of membership functions for input and output variables are described and analysed. The control strategy consisting of the expert rules is then validated using experimental data from a naturally ventilated test room. The test room is located in a sheltered area and air flow inside the room, the air pressures and velocities across the openings together with indoor air temperature and velocity at four locations and six different levels were measured. Validation of the controller is performed in the test room by measuring the air distribution and thermal comfort inside the room with no control action. These data are then compared to the air temperature and velocity with the controller in action. The initial results are presented here, which shows that the controller is capable of providing better thermal comfort inside the room. (author)

    In order to understand and to control the indoor thermal behavior in buildings, it is necessary to know the origin of the energies coming into and outside the building, identifying the geometric factors and physical properties, that can modify the thermal balance of the system. In this work, we analyze the thermal behavior of a building experimentally, related with its exterior conditions. Specifically, we analyze the thermal response indoors at different distances from the building envelope, which implies different thermal insulation situations. Supported on temperature measurements in a residential building, which is representative of local construction styles (adjacent other buildings), we analyze the thermal response effects depending on the distances between the considered points and the envelope and on the insulation between both. Applying a methodology based on experimental transfer functions of buildings, the thermal behavior in the temporary and frequency domains is evaluated. With this methodology, it is possible to visualize certain phenomena and to obtain thermal parameters that characterize the dynamic aspects of the thermal response. The main scope is to extract information from the building analysis, in order to extrapolate the behavior conclusions to a proper thermal design of similar constructions. From the thermal responses analysis at different spatial localization, we conclude that the distance from the building envelope (and also its properties) has a great influence on thermal inertia effects, which can modify importantly the thermal response. This phenomena has a parallelism with the skin effect of the magnetic fields penetration in conductors. The spatial localization implies a certain thermal mass involved in each case, which controls the penetration of exterior thermal oscillation.

    Biquand, Sylvain; Zittel, Benoit

    2012-01-01

    Corporate Social Responsibility (CSR) is now considered in large and global companies and the recent publication of the ISO 26000 standard clarifies the targets. Based on our consultancy's experience for fifteen years in ergonomics mainly in French small and medium enterprises, we developed a label to coax and value efforts of companies in dealing with health and safety at the work place as required by ISO 26000 paragraph 6.4. The formal approach of ISO describes what should be achieved but gives no cue on how actual conditions of work should be improved. The label, called Démarche T (ie Process W where W stands for work) aims the management of work conditions as a process, giving visibility and credit to companies for their continuous involvement in the matter. We describe the items and processes that are part of our assessment. We first conduct an ergonomic diagnosis including the analysis of records on health, physical and psychological well-being, observations at the workplace and interviews with the workers. This diagnosis is followed by recommendations. The fulfillment of these is assessed yearly. Items under assessment include: - ergonomics, health and safety in the companies statements and their impact in actual project management; - relations with workers through the committee for health and safety; - actual results on health, safety and work conditions. On a local level, we give the companies passing the label a competitive edge in recruiting better candidates motivated by good work conditions, and help them fulfill ISO 26000 requirements, an increasingly decisive advantage to benefit from public regional and European support. Our paper describes the diagnosis and follow-up process.

  1. Relevance feature selection of modal frequency-ambient condition pattern recognition in structural health assessment for reinforced concrete buildings

    Directory of Open Access Journals (Sweden)

    He-Qing Mu

    2016-08-01

    Full Text Available Modal frequency is an important indicator for structural health assessment. Previous studies have shown that this indicator is substantially affected by the fluctuation of ambient conditions, such as temperature and humidity. Therefore, recognizing the pattern between modal frequency and ambient conditions is necessary for reliable long-term structural health assessment. In this article, a novel machine-learning algorithm is proposed to automatically select relevance features in modal frequency-ambient condition pattern recognition based on structural dynamic response and ambient condition measurement. In contrast to the traditional feature selection approaches by examining a large number of combinations of extracted features, the proposed algorithm conducts continuous relevance feature selection by introducing a sophisticated hyperparameterization on the weight parameter vector controlling the relevancy of different features in the prediction model. The proposed algorithm is then utilized for structural health assessment for a reinforced concrete building based on 1-year daily measurements. It turns out that the optimal model class including the relevance features for each vibrational mode is capable to capture the pattern between the corresponding modal frequency and the ambient conditions.

    2015-01-01

    An acoustic survey of secondary schools in England has been undertaken. Room acoustic parameters and background noise levels were measured in 185 unoccupied spaces in 13 schools to provide information on the typical acoustic environment of secondary schools. The unoccupied acoustic and noise data were correlated with various physical characteristics of the spaces. Room height and the amount of glazing were related to the unoccupied reverberation time and therefore need to be controlled to reduce reverberation to suitable levels for teaching and learning. Further analysis of the unoccupied data showed that the introduction of legislation relating to school acoustics in England and Wales in 2003 approximately doubled the number of school spaces complying with current standards. Noise levels were also measured during 274 lessons to examine typical levels generated during teaching activities in secondary schools and to investigate the influence of acoustic design on working noise levels in the classroom. Comparison of unoccupied and occupied data showed that unoccupied acoustic conditions affect the noise levels occurring during lessons. They were also related to the time spent in disruption to the lessons (e.g., students talking or shouting) and so may also have an impact upon student behavior in the classroom.

    De Rosa, C.; Basso, M.; Fernandez, J.C. [Laboratorio de Ambiente Humano y Vivienda, Mendoza (AR)] [and others

    2000-07-01

    Four energy-efficient demonstration school buildings were built in the western province of Mendoza, Argentina, in 1999, as part of a massive building program required to implement the new Federal Education Plan. The buildings should make medium use of bioclimatic strategies and daylighting. The aspects of typology of the classroom tiers became immediately apparent as one of the main conditioners of the overall scheme. Three different alternative schemes were designed and built. A deeper analysis of these and other possible alternatives were thought essential for future constructions of the type. Four typologies of the classroom tier, using the same, locally available technology, are being comparatively assessed in the aspects of energy efficiently, thermal and luminous comfort, construction and operation costs and environmental impact (LCA). The paper presents the provisional results of the two first items only: energy efficiency and thermal comfort. While all four schemes evaluated are believed to be ''workable'', differences will tend to favour some the other according to context situations. Volumetric Loss Coeff. range from 1.09 to 1.24 W/Km{sup 3}. Solar savings fractions for the school operation hours vary between: 82.83 and 91.58%. Work is being continued to cover all the analysis items in a combined way. (author)

  5. Energy performance of solar-assisted liquid desiccant air-conditioning system for commercial building in main climate zones

    International Nuclear Information System (INIS)

    Qi, Ronghui; Lu, Lin; Huang, Yu

    2014-01-01

    Highlights: • Simulation of solar liquid desiccant AC system in four climate regions was conducted. • System performance was determined by relationship of sensible and latent cooling load. • For humid area, saving amount is large by handling latent load with solar energy. • For dry area, electricity saving rate is considerable due to the high COP of chillers. • For buildings with mild SHR, the system performance was not as good as others. - Abstract: Liquid desiccant air-conditioning (LDAC) system, which consists of a liquid desiccant ventilation system for dehumidification and an air-handling unit for cooling, has become a promising alternative for conventional technology. To evaluate its feasibility and applicability, the simulation of solar-assisted LDAC (SLDAC) in commercial buildings in five cities of four main climate regions were conducted, including Singapore in Tropical, Houston and Beijing in Temperate, Boulder in Arid and Los Angeles in Mediterranean. Results showed that the system’s performance was seriously affected by the ratios of building’s sensible and latent cooling load. For buildings located in humid areas with low sensible-total heat ratio (SHR), the electricity energy reduction of SLDAC was high, about 450 MW h in Houston and Singapore, which accounted for 40% of the total energy consumption in cooling seasons. The cost payback period was as short as approximately 7 years. The main reason is that the energy required for handling the moisture could be saved by liquid desiccant dehumidification, and the regeneration heat could be covered by solar collectors. For buildings in dry climate with high SHR, the total cooling load was low, but up to 45% electricity of AC system could be saved in Boulder because the chiller COP could be significantly improved during more than 70% operation time. The cost payback period was around 22 years, which was acceptable. However, for the buildings with mild SHR, such as those in Beijing and Los

    Full Text Available OBJECTIVE: To verify the physical, functional, hygienic, and sanitary conditions of the food services of municipal schools located in the Brazilian Midwest region. METHODS: This is a cross-sectional study of 296 school food services conducted from February to June 2012. The food services were assessed by a semi-structured check list divided into the following sections: physical conditions, available equipment, food handlers' conduct, and food service cleaning processes and procedures. The study variables were classified as compliant or noncompliant with the regulations passed by the National Sanitary Surveillance Agency. RESULTS: Noncompliances were found in all study food services, especially with respect to food service conditions, and the wiring and plumbing in the food preparation area. In this section, 62.7 to 95.9% of the food services did not comply with nine out of the thirteen study items. The main problems were: poorly cleaned external areas, deteriorated walls, floors, ceilings, roofs, drains, and roof gutters; and unscreened doors and windows, allowing the entrance of insects; among others. The main noncompliance regarding processes and procedures was the uncontrolled temperature of the ready-to-eat foods. CONCLUSION: The conditions of the study food services are unsatisfactory for the production of safe meals, possibly compromising meal quality, food safety, and the effectiveness of the School Food Program.

An internet programme has been developed with the aim of facilitating schools' access to benchmarks and to evaluate energy consumption. The overall purpose is to create increased attention to the electricity consumption of each separate school by publishing benchmarks which take the schools' age and number of pupils as well as after school activities into account. Benchmarks can be used to make green accounts and work as markers in e.g. energy conservation campaigns, energy management and for educational purposes.

    Legacy lead and copper components are ubiquitous in plumbing of large buildings including schools that serve children most vulnerable to lead exposure. Lead and copper samples must be collected after varying stagnation times and interpreted in reference to different thresholds. A total of 130 outlets (fountains, bathroom and kitchen taps) were sampled for dissolved and particulate lead as well as copper. Sampling was conducted at 8 schools and 3 institutional (non-residential) buildings served by municipal water of varying corrosivity, with and without corrosion control (CC), and without a lead service line. Samples included first draw following overnight stagnation (>8h), partial (30 s) and fully (5 min) flushed, and first draw after 30 min of stagnation. Total lead concentrations in first draw samples after overnight stagnation varied widely from 0.07 to 19.9 μg Pb/L (median: 1.7 μg Pb/L) for large buildings served with non-corrosive water. Higher concentrations were observed in schools with corrosive water without CC (0.9-201 μg Pb/L, median: 14.3 μg Pb/L), while levels in schools with CC ranged from 0.2 to 45.1 μg Pb/L (median: 2.1 μg Pb/L). Partial flushing (30 s) and full flushing (5 min) reduced concentrations by 88% and 92% respectively for corrosive waters without CC. Lead concentrations were 45% than values in 1st draw samples collected after overnight stagnation. Concentrations of particulate Pb varied widely (≥0.02-846 μg Pb/L) and was found to be the cause of very high total Pb concentrations in the 2% of samples exceeding 50 μg Pb/L. Pb levels across outlets within the same building varied widely (up to 1000X) especially in corrosive water (0.85-851 μg Pb/L after 30MS) confirming the need to sample at each outlet to identify high risk taps. Based on the much higher concentrations observed in first draw samples, even after a short stagnation, the first 250mL should be discarded unless no sources

    Full Text Available Since the 1990s, governance changes, including customer choice agendas, have permeated the public sector and, consequently, welfare sector professionals’ work. One example is the education sector. The aim of this paper is to identify and discuss avenues for further research when it comes to teachers’ working conditions in the light of current choice agendas. This is accomplished by presenting an overview of previous studies on implications of the reforms for teachers’ working conditions. How are these conditions described in relation to the current school choice agenda in Sweden? What directions should be applied to increase knowledge of these conditions? We conclude by identifying some avenues for further research: the issues of organization of work, temporal and spatial dimensions of working conditions, and finally comparative studies of various forms, are suggested as warranting further investigation to highlight the diversified labor market in which teachers find themselves today.Keywords: Competition, governance change, privatization, professional work, school choice, Sweden, teaching profession, working conditions

    This study examined ways that young adults with mental illnesses (1) currently use social networking; and (2) how they would like to use a social networking site tailored for them. The authors examined differences between those with mental health conditions and those without. An online survey was administered by the National Alliance on Mental Illness (NAMI) to 274 participants; of those, 207 reported being between 18 and 24 years old. The survey included questions about current social networking use, the key resources respondents believed young adults living with mental illness need, and the essential components that should be included in a social networking site specifically tailored to young adults living with mental illness. Pearson Chi-square analyses examined the differences between those who reported having a mental illness and those who did not. Results indicate that almost all (94%) participants with mental illnesses currently use social networking sites. Individuals living with a mental illness are more likely than those not living with a mental illness to report engaging in various social networking activities that promote connectivity and making online friends. Individuals living with mental illnesses are also more likely to report wanting resources on independent living skills and overcoming social isolation available on a social networking site. Young adults living with mental illnesses are currently using social networking sites and express high interest in a social networking site specifically tailored to their population with specific tools designed to decrease social isolation and help them live more independently. These results indicate that practitioners should themselves be aware of the different social networking sites frequented by their young adult clients, ask clients about their use of social networking, and encourage safe and responsible online behaviors.

    The quality of lighting plays an important role in the psychological and biological processes of people. Research shows that student performace increases in a good visual environment. At the same time, the energy use of artificial lighting is one of the major cost items of schools. This was a major reason to conduct research into optimal utilisation of daylight in schools.(mk) [Dutch] De lichtkwaliteit speelt een belangrijke rol bij de psychologische en biologische processen van mensen. Uit onderzoek blijkt dat in een goede visuele omgeving de prestaties van leerlingen toenemen. Gelijktijdig is het energiegebruik voor kunstlicht een van de belangrijkste kostenposten van scholen. Alle reden om onderzoek te doen naar optimaal gebruik van daglicht in scholen.

  15. Influence of precipitations, buildings and over increase of radioactive emission in the population dose calculation under accident conditions

    The influence of precipitations is analyzed, as well as of buildings and emission over increase on the dosis produced on the population as a consequence of some postulated accidents in Atucha II nuclear power plant. The following conclusions were achieved: the calculations performed without considering the above mentioned effects are conservative, excluding the case in which the precipitation is very close to the emission source. In this case, the maximal difference observed was 20% for class C and 5% for class D, at 1 km from source, with a decreasing difference according to the distance. The doses calculated without building effect were approximately 25% greater than those calculated considering this effect for class E and 40% for class F, at 1 km from the source. The difference decreases with distance and increases with the stability of atmospheric conditions. This behaviour is also observed with the over increase effect. In this case, the maximal observed differences were of one order of magnitude for class E and three orders for class F, at 1 km from the source. (Author)

    A Trichoderma atroviride strain was isolated from a water-damaged office and the production of microbial volatile organic compounds (MVOCs) was investigated by means of headspace solid phase microextraction GC-MS. Different growth conditions (substrate, temperature, relative humidity) were selected, resembling indoor parameters, to elucidate a possible relationship between MVOCs, produced by Trichoderma atroviride, and the Sick Building Syndrome. In general, the range of MVOCs and the emitted quantities were larger on malt extract agar (MEA) than on wallpaper and plasterboard. Particular attention was dedicated to the volatile marker 6-pentyl-2-pyrone, a compound produced in high quantities on MEA, and its mucosal irritation potency was shown in a slug mucosal irritation assay. Some compounds characteristic for growth on specific building materials were detected, e.g. 2-ethylcyclopentanone, menthone, iso-menthone and trans-p-menth-2-en-7-ol on plasterboard and 4-heptanone and 1-octen-3-ol on wallpaper. Relative humidity and substrate had a more important effect on MVOC production than temperature. (author)

    Most previous research on indoor environments and health has studied school children or occupants in non-school settings. This investigation assessed building-related health symptoms and classroom characteristics via telephone survey of New York State school teachers. Participants were asked about 14 building-related symptoms and 23 classroom characteristics potentially related to poor indoor air quality (IAQ). Poisson regression analysis was used to assess the relationship between these symptoms and each classroom characteristic, controlling for potential confounders. About 500 teachers completed the survey. The most frequently reported classroom characteristics included open shelving (70.7%), food eaten in class (65.5%), dust (59.1%), and carpeting (46.9%). The most commonly reported symptoms included sinus problems (16.8%), headache (15.0%), allergies/congestion (14.8%), and throat irritation (14.6%). Experiencing one or more symptoms was associated most strongly with reported dust (relative risk (RR) = 3.67; 95% confidence interval (CI): 2.62-5.13), dust reservoirs (RR = 2.13; 95% CI: 1.72-2.65), paint odors (RR = 1.73; 95% CI: 1.40-2.13), mold (RR = 1.71; 95% CI: 1.39-2.11), and moldy odors (RR = 1.65 95% CI: 1.30-2.10). Stronger associations were found with increasing numbers of reported IAQ-related classroom characteristics. Similar results were found with having any building-related allergic/respiratory symptom. This research adds to the body of evidence underscoring the importance to occupant health of school IAQ. Teachers play an important role in educating children, and teacher well-being is important to this role. Health symptoms among New York teachers while at work are common and appear to be associated with numerous characteristics related to poor classroom IAQ. Improving school Indoor Air Quality may reduce sickness and absenteeism and improve teacher performance. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Leaders @ Play is a park after-school program for urban middle school youth designed to leverage recreational activities for social emotional learning. Mental health and park staff co-facilitated sports and games to teach and practice problem solving, emotion regulation, and effective communication. Additional practice occurred during multi-family groups and summer internships as junior camp counselors. We examined feasibility and promise via an open trial (n = 3 parks, 46 youth, 100 % African American, 100 % low-income, 59 % female, M = 13.09 years old). Improvements in social skills and reductions in problem behaviors lend support to after school programs as a space for mental health promotion.

    We administered a self-reporting questionnaire survey regarding the mental health conditions of high school students and attitudes of students and their teachers toward students' mental health issues. In addition, we discussed the requirements for high school students' mental health support system. The subjects were 3,312 students and 208 teachers in four Shizuoka prefectural public high schools in 2009. University Personality Inventory (UPI) is usually conducted to assess university students' mental state and is a questionnaire that high school students can answer easily. Therefore, we adopted UPI for this survey. UPI was composed of 56 unhealthy and 4 healthy condition items. High school students completed the UPI and determined the sum of unhealthy condition items; a higher score indicated a poorer mental health status. The average UPI score of all students (n = 3,312) was 12.7 points, and that of females (n = 1,217)was 15.2 points, which was significantly higher than the 11.3 points of males (n = 2,095). Those with scores > or = 30 points (7.5%), which was more than half of the maximum score, were designated as the High Score (HS) group and considered to have poor mental health. Those with scores of > or = 40 (1.4%) seemed to have very poor mental health, and there was concern that they may be suffering from psychosis. Our observations indicated that HS students were likely to avoid seeking help regarding mental health issues, which was especially true for male HS students. The majority of students chose their friends and parents as advisers, but HS students were significantly more likely to choose advisers who were engaged in jobs related to medical work. Students in both the HS and non-HS groups who did not wish to consult anyone else about their mental conditions wanted to be approached by those around them. High school teachers hesitated to intervene with mentally disturbed students and attempted to resolve problems within the school. Thus, it appears

    In Luxemburg, energy consumption in the building and housing sector has been significantly increasing over the last years. From 1990 to 2005, the fraction of the tertiary sector (including private and public households), compared to the entire national energy consumption, increased from only 20% to 31% [ENEL, 2008]. An assessment of the energy saving potential of buildings requires a comprehensive data basis with real consumption figures that are not yet available. Assessments on energy saving measures conducted so far are only based on rough estimates. One focus of this study was to create a priori a detailed energy consumption database for new ''School and Administrative Buildings'' for Luxembourg. These are both groups pursuant to the EU Directive [EU, 2010] and cover a major part of the building and housing sector in Luxembourg besides residential buildings. Based on the samples collected, it was able to expand the figures to the entire country using mathematical methods and the medium heat and electricity consumption of these two types of buildings. After collecting some details about each object, it was able to analyze the influence of different parameters, such as building age, size, type, glass fraction etc., on energy consumption using multivariate statistical methods. A posteriori, the results from the database were verified using parameter studies to existing objects and one object still under construction. Based on this, important key parameters relevant for both energy savings and thermal comfort could be found. This knowledge are necessary to understand energy flows within buildings better and, based on this, to be able meeting the nearly zero energy buildings requirements as set out by the EU Directive in the years to come. In particular, this study focused on the negative effects of growing window areas on the energy consumptions and discussed them thoroughly. Also, we tested and/or provided calculational evidence of further

    Full Text Available Introduction: Reading-room is a place where special lighting conditions are required to make the reader feel comfortable and satisfied.. Lighting requirements are enclosed in the Polish Standard PN-EN 12464-1:2004. Accordingly, illuminance in the reading-rooms should be 500 lx. The aim of the study was to measure illuminance in reading-rooms in various libraries and make relative comparisons to standard values. Material and methods: Measurements of illuminance were performed in 22 reading-rooms in Silesia Voivodeship. Half of them were made in public libraries and half in reading-rooms at junior lower high schools. Illuminance was measured in 5 measurement points in reading-rooms by digital lux meter Lx-105 manufactured by Lutron. Furthermore , 100 readers of school libraries and 89 readers of public libraries completed a questionnaire on lighting conditions in these places. Results: Only 5 out of 22 reading-rooms meet the requirements of the Polish Standard concerning illuminance. Only in one reading room at junior lower high school illuminance exceeded 500 lx. In two other reading places the requirements were met due to additional desk lamps. Despite the results, 76.4% of approached readers of public libraries and 60% of pupils think that lighting in readingrooms is satisfactory and almost 63% of the readers and 53% of the pupils don’t demand additional lighting. Conclusions: Most of the scrutinized reading rooms do not meet lighting requirements according to the Polish Standard. Lighting conditions in school libraries are worse than in public libraries. According to the respondents lighting in public libraries is adequate.

    There are few longitudinal studies on sick building syndrome (SBS), which include ocular, nasal, throat, and dermal symptoms, headache, and fatigue. We studied the associations between selected microbial components, fungal DNA, furry pet allergens, and incidence and remission of SBS symptoms in schools in Taiyuan, China. The study was based on a two-year prospective analysis in pupils (N = 1143) in a random sample of schools in China. Settled dust in the classrooms was collected by vacuum cleaning and analyzed for lipopolysaccharide (LPS), muramic acid (MuA), and ergosterol (Erg). Airborne dust was collected in Petri dishes and analyzed for cat and dog allergens and fungal DNA. The relationship between the concentration of allergens and microbial compounds and new onset of SBS was analyzed by multi-level logistic regression. The prevalence of mucosal and general symptoms was 33% and 28%, respectively, at baseline, and increased during follow-up. At baseline, 27% reported at least one symptom that improved when away from school (school-related symptoms). New onset of mucosal symptoms was negatively associated with concentration of MuA, total LPS, and shorter lengths of 3-hydroxy fatty acids from LPS, C14, C16, and C18. Onset of general symptoms was negatively associated with C18 LPS. Onset of school-related symptoms was negatively associated with C16 LPS, but positively associated with total fungal DNA. In general, bacterial compounds (LPS and MuA) seem to protect against the development of mucosal and general symptoms, but fungal exposure measured as fungal DNA could increase the incidence of school-related symptoms. - Highlights: → SBS symptoms increased during the two-year follow-up period in school children in Taiyuan, China → We studied the associations between selected microbial components and incidence and remission of SBS symptoms. → Bacterial compounds (LPS and MuA) seem to protect against the development of mucosal and general symptoms. → Fungal

    Bandung is one of the most important colonial cities in Indonesia. In the early 20th century the capital city of Dutch East-Indies Government planned to move in Bandung. Critical infrastructures were intensively built during that period, such as streets and railways, houses, governmental buildings, train stations, hospitals and educational facilities. Besides the famous campus of Technische Hoogeschool te Bandoeng (ITB), still in the same period, several schools were also constructed. One of the most important schools was Hoogere Burgerschool in Bandung (HBS Bandung), now SMUN 3 and 5, Bandung designed by Charles Prosper Wolff Schoemaker and constructed in 1915. HBS Bandung was the fourth HBS constructed by Dutch East Indies Government, therefore became important and put itself as a reference for the later school buildings in Bandung. This study is analyzing how the architects’ frame of mind in producing this design works. Survey and direct data collecting were used to take the exact embodiment of building design. Usage and functional analysis were also used to match space and other standard used in a school building at that time. This study will give an understanding of building typology of school during the Dutch Colonial Period in Indonesia.

    We evaluated the association between meteorological conditions and sports deaths at elementary, junior high and senior high schools. Data were collected from attached documents such as accident reports and death certificate records in the National Agency for the Advancement of Sports and Health in Japan. Evaluation of seasonal variation showed a significant concentration of deaths from heat disorders and drowning in July and August. When heart disease was evaluated according to the sports situation, significant seasonal variation with a high number of deaths in September December was observed in sports events. Concerning circadian variation, deaths from heart disease showed a high peak at 10:00 11:00 a.m. in physical education classes and sports events, and at 2:00 5:00 p.m. in sports club activities. Analysis using a multiple logistic model showed a significantly lower odds ratio from heart disease and a significantly higher odds ratio from heat disorders at a wet bulb globe temperature of ≥21.0°C than at activities was significantly lower on days with rainfall than on days without rainfall. According to the school categories in heart diseases, the odds ratio in girls in elementary school was significantly higher than that in boys, but the odds ratio in girls in senior high school was significantly lower than that in boys.

    Highlights: • A modified bin method is adopted to propose and optimize the EER schemes. • A case study is presented to demonstrate the analysis procedures of EER schemes. • Pertinent EER schemes for HVAC systems are proposed for the object building. - Abstract: Poor thermal performance of building envelop and low efficiencies of heating, ventilating and air-conditioning (HVAC) systems can always be found in the existing office buildings with large energy consumption. This paper adopted a modified bin method to propose and optimize the energy efficiency retrofit (EER) schemes. An existing office building in Tianjin was selected as an example to demonstrate the procedures of formulating the design scheme. Pertinent retrofit schemes for HVAC system were proposed after the retrofit of building envelop. With comprehensive consideration of energy efficiency and economic benefits, the recommended scheme that could improve the overall energy efficiency by 71.20% was determined

    In 2012, the School of Earth Sciences (SES) at Stanford University sponsored two summer undergraduate research programs. Here we describe these programs and efforts to build a cohesive research cohort among the programs' diverse participants. The two programs, the Stanford School of Earth Sciences Undergraduate Research (SESUR) Program and Stanford School of Earth Sciences Summer Undergraduate Research in Geoscience and Engineering (SURGE) Program, serve different undergraduate populations and have somewhat different objectives, but both provide students with opportunities to work on strongly mentored yet individualized research projects. In addition to research, enrichment activities co-sponsored by both programs support the development of community within the combined SES summer undergraduate research cohort. Over the course of 6 to 9 months, the SESUR Program engages Stanford undergraduates, primarily rising sophomores and juniors, with opportunities to deeply explore Earth sciences research while learning about diverse areas of inquiry within SES. Now in its eleventh year, the SESUR experience incorporates the breadth of the scientific endeavor: finding an advisor, proposal writing, obtaining funding, conducting research, and presenting results. Goals of the SESUR program include (1) providing a challenging and rewarding research experience for undergraduates who wish to explore the Earth sciences; (2) fostering interdisciplinary study in the Earth sciences among the undergraduate population; and (3) encouraging students to major or minor in the Earth sciences and/or to complete advanced undergraduate research in one of the departments or programs within SES. The SURGE Program, now in its second year, draws high performing students, primarily rising juniors and seniors, from 14 colleges and universities nationwide, including Stanford. Seventy percent of SURGE students are from racial/ethnic backgrounds underrepresented in STEM fields, and approximately one

    To provide an overview of the status of monitoring and evaluation (M&E) of school feeding across sub-Saharan Africa and to reflect on the experience on strengthening M&E systems to influence policy making in low-income countries. Literature review on the M&E of school feeding programmes as well as data from World Food Programme surveys. Sub-Saharan Africa. Countries implementing school feeding. Only two randomized controlled impact evaluations have been implemented in sub-Saharan Africa. Where M&E data collection is underway, the focus is on process and service delivery and not on child outcomes. M&E systems generally operate under the Ministry of Education, with other Ministries represented within technical steering groups supporting implementation. There is no internationally accepted standardized framework for the M&E of school feeding. There have been examples where evidence of programme performance has influenced policy: considering the popularity of school feeding these cases though are anecdotal, highlighting the opportunity for systemic changes. There is strong buy-in on school feeding from governments in sub-Saharan Africa. In response to this demand, development partners have been harmonizing their support to strengthen national programmes, with a focus on M&E. However, policy processes are complex and can be influenced by a number of factors. A comprehensive but simple approach is needed where the first step is to ensure a valid mandate to intervene, legitimizing the interaction with key stakeholders, involving them in the problem definition and problem solving. This process has been facilitated through the provision of technical assistance and exposure to successful experiences through South–South cooperation and knowledge exchange.

  18. "Can we talk?" Using critical self-reflection and dialogue to build diversity and change organizational culture in nursing schools.

    Science.gov (United States)

    Terhune, Carol Parker

    2006-01-01

    Nursing is often cited as a homogenous profession composed of a predominance of white females. It is sometimes posited that this homogeneity might be a contributor to the disparity of nursing care available to minority populations (Blakeney, 2002; Leininger, 1991). Today's nursing students do not mirror the nation's population as only 12.3% of RNs represent racial or ethnic minority groups (AACN, 2001). The absence of sufficiently diverse students in nursing schools, may have led to a dearth of qualified providers in underrepresented neighborhoods. Building diversity in nursing schools prepared specifically to reduce health disparities is, and will continue to be a challenge. While, some schools are beginning to yield successful returns, many are still searching for answers. The answer is not as simple as "increasing the numbers" or sending people to training seminars or conferences. This article focuses on what the author believes to be a preliminary and critical step to begin an effective and successful diversity initiative--critical self-reflection and dialogue. This involves the examination and deconstruction of old paradigms, assumptions, and prejudices, individually and collectively held and the construction of space, respect, and humility to discuss self in relation to "other."

    2014-01-01

    Full Text Available The paper reveals the research findings concerning a complicated process of academic staff formation in the secondary school. The main determinants of the process include the discrepancy between the actual development level of academic staff and the existing requirements of pedagogic society. The author denotes the main motives for academic staff development: moral and financial incentives for professional growth, new educational tasks, unsatisfactory social status of educational institution, etc; and identifies the complex of objective and subjective conditions positively affecting the given process. According to the author, the main priority should be given to the methodological provision of academic staff, integration of their activity, and stimulation of informational, methodical, and organizational channels of school activity. In conclusion, the paper considers the principles of life-long teacher training, corporate cooperation, partnership and solidarity, and discusses the technological structure of academic staff development, based on the competence model of education.

    2014-02-01

    Full Text Available The main object of this study is the reconstruction, renovation and modernization of the housing built in the period 1975—1985. These buildings have low energy efficiency due to the poor thermal insulation properties of the walls. These apartments do not meet the necessary requirements for year round warmth and comfort.Reconstruction is more preferable, than new-build, because of the cost saving for the land acquisition. Reconstruction is generally 1.5 times cheaper than new-build with 25—40 % reduced cost on building materials and engineering infrastructure.Increasing the width of the apartment blocks from 12 to 15 m can save 9—10 % on the consumption of thermal energy for heating and reduce the m2 construction cost by 5.5—7.0 %. In—5-9 storey high-rise buildings the savings are 3—5 %.Therefore, the width of the apartment block should preferably be between 9—12 m but could be extended to 18 m. The depth of the apartments themselves will be 5.4 — 6.0 —7.2 or 9.0 m. During the reconstruction of 5-storey residential buildings (Building Type105 in a seismic zone, an increase in the width of the block and the lateral stiffness of the building is achieved by building a new reinforced concrete (RC frame on both sides of the building with a depth of between 2 and 6 m. This technique is especially effective in increasing the seismic resistance of the building. Self-supporting walls of cellular concrete blocks (density 600 kg/m3 and a thickness of 300 mm are constructed on the outside of the frame, taking care to avoid cold bridges.Model studies have shown that in the conditions of hot-arid climate the thickness of the air gap in a ventilated facade does not significantly change the cooling-energy consumption of the building, and heating consumption is significantly increased. The building's energy consumption is most influenced by the volume of the air in the air gap. By increasing the ventilation rate in the air gap, the energy

    Full Text Available The article determines that introduction and implementation of the mechanism for foreign economic adaptation of machine-building enterprises to the conditions of the European integration processes requires constant monitoring of the processes of export-import operations and the adaptation activities to identify current problems and avoid risks. It has been found that one of the monitoring instruments is the system of indicators, which provides to evaluate the efficiency of use of the mechanism for foreign economic adaptation of a machine-building enterprise by comparing the values of the obtained indicators after accomplishing adaptation changes with the values of the indicators of previous periods. It is suggested to determine efficiency of adaptation of foreign economic activity of machine-building enterprises to conditions of deepening of the European integration process of Ukraine by means of: index of change of volume of exported production of a machine-building enterprise to the EU countries; weighted average of the change in the share of the European market, which is covered by the enterprise’s products; indicator of efficiency of exports of production of a machine-building enterprise to the European Union countries; indicator of the index of changes in the volume of permanent orders from European partners; integral indicator of efficiency of use of adaptive potential of a machine-building enterprise in conditions of integration processes.

    Full Text Available The article deals with the problem of using a Wimmelbuch as visual teaching aids for forming foreign language communication skills at English lessons at primary school. Nowadays much attention is given to the problem of forming and improving foreign language communication skills of primary schoolchildren in scholarly works and case studies. The aim of the article is to analyze the problem of implementing visual teaching aids, in particular a Wimmelbuch while forming foreign language communication skills at English lessons at primary school. The aim involves the following tasks: to define the factors that influence forming primary schoolchildren’s communicative competence; to find out the pedagogical conditions of the problem of using visual aids (a Wimmelbuch in teaching a foreign language at primary school. Such methods as analysis, synthesis, and systematization are used to achieve the aim of the article. They help to get to the essence of the outlined problem and pass from a less general idea to more general one logically. Much attention is given to the factors that influence forming primary schoolchildren’s communicative competence. The pedagogical conditions of the problem of using a Wimmelbuch in learning a foreign language at primary school are determined. It is found out that the current labor market conditions require from the organization of the educational process at secondary school to lay the strong foundation for the formation of primary professional skills of an individual. Therefore, teaching English should have both the communicative-oriented character and professionally-directed one that promotes developing consciousness; expanding students’ outlook, their creative development, personal culture and competence; forms recognizing a multicultural world. Nowadays there are the following features of the communicative approach in learning a foreign language: a a language is examined as a means of communication, preference is

    2016-11-01

    Full Text Available Abstract Background Comprehensive School Health (CSH is an internationally recognized framework that holistically addresses school health by transforming the school culture. It has been shown to be effective in enhancing health behaviours among students while also improving educational outcomes. Despite this effectiveness, there is a need to focus on how CSH is implemented. Previous studies have attempted to uncover the conditions necessary for successful operationalization, but none have described them in relation to a proven best practice model of implementation that has demonstrated positive changes to school culture and improvements in health behaviours. Methods The purpose of this research was to identify the essential conditions of CSH implementation utilizing secondary analysis of qualitative interview data, incorporating a multitude of stakeholder perspectives. This included inductive content analysis of teacher (n = 45, principal (n = 46, and school health facilitator (n = 34 viewpoints, all of whom were employed within successful CSH project schools in Alberta, Canada between 2008 and 2013. Results Many themes were identified, here called conditions, that were divided into two categories: ‘core conditions’ (students as change agents, school-specific autonomy, demonstrated administrative leadership, dedicated champion to engage school staff, community support, evidence, professional development and ‘contextual conditions’ (time, funding and project supports, readiness and prior community connectivity. Core conditions were defined as those conditions necessary for CSH to be successfully implemented, whereas contextual conditions had a great degree of influence on the ability for the core conditions to be obtained. Together, and in consideration of already established ‘process conditions’ developed by APPLE Schools (assess, vision, prioritize; develop and implement an action plan; monitor, evaluate, celebrate

    International Nuclear Information System (INIS)

    Ferraro, V.; Igawa, N.; Marinelli, V.

    2010-01-01

    A calculation code, named INLUX-DBR, is presented, which is a modified version of INLUX code, able to predict the illuminance distribution on the inside surfaces of a room with six walls and a window, and on the work plane. At each desired instant the code solves the system of the illuminance equations of each surface element, characterized by the latter's reflection coefficient and its view factors toward the other elements. In the model implemented in the code, the sky-diffuse luminance distribution, the sun beam light and the light reflected from the ground toward the room are considered. The code was validated by comparing the calculated values of illuminance with the experimental values measured inside a scale model (1:5) of a building room, in various sky conditions of overcast, clear and intermediate days. The validation is performed using the sky luminance data measured by a sky scanner and the measured beam illuminance of the sun as input data. A comparative analysis of some of the well-known calculation models of sky luminance, namely Perez, Igawa and CIE models was also carried out, comparing the code predictions and the measured values of inside illuminance in the scale model.

    Burden of treatment refers to the workload of health care as well as its impact on patient functioning and well-being. We set out to build a conceptual framework of issues descriptive of burden of treatment from the perspective of the complex patient, as a first step in the development of a new patient-reported measure. We conducted semistructured interviews with patients seeking medication therapy management services at a large, academic medical center. All patients had a complex regimen of self-care (including polypharmacy), and were coping with one or more chronic health conditions. We used framework analysis to identify and code themes and subthemes. A conceptual framework of burden of treatment was outlined from emergent themes and subthemes. Thirty-two patients (20 female, 12 male, age 26-85 years) were interviewed. Three broad themes of burden of treatment emerged including: the work patients must do to care for their health; problem-focused strategies and tools to facilitate the work of self-care; and factors that exacerbate the burden felt. The latter theme encompasses six subthemes including challenges with taking medication, emotional problems with others, role and activity limitations, financial challenges, confusion about medical information, and health care delivery obstacles. We identified several key domains and issues of burden of treatment amenable to future measurement and organized them into a conceptual framework. Further development work on this conceptual framework will inform the derivation of a patient-reported measure of burden of treatment.

    Universities, because of their vast human and fiscal resources, can play the central role in assisting in the development of school-centered community development programs that make youth development their top priority. The Futures Academy, a K-8 public school in the Fruit Belt, an inner-city neighborhood in Buffalo, New York, offers a useful model of community development in partnership with the Center for Urban Studies at the State University of New York at Buffalo. The goal of the project is to create opportunities for students to apply the knowledge and skills they learn in the classroom to the goal of working with others to make the neighborhood a better place to live. The efforts seek to realize in practice the Dewey dictum that individuals learn best when they have "a real motive behind and a real outcome ahead."

    For clinical nurses and nursing academics wishing to participate in research, there are several logistical issues such as high workloads, lack of time and poor research skills and knowledge that can impede research being undertaken. To address these issues, La Trobe University in partnership with one of Melbourne's acute care hospitals developed a clinical school with the aim of delivering postgraduate courses and undertaking collaborative clinically focused nursing research. Clinical issues were identified jointly between university academics and clinical nursing staff. Research questions were developed to examine these issues with the clinical school staff facilitating the research process. Research has been undertaken in many specialty areas including emergency, cardiac and intensive care nursing and diabetes. The success of this collaboration is evident with many studies being undertaken and consequently dissemination of research findings published (with clinicians being the primary author on many papers), presentations at national and international conferences by clinical staff as well as an increased enrollment into masters and doctoral programmes. The presence of the clinical school at the hospital has been beneficial both to clinicians and nurse academics and resulted in developing a positive research environment. More importantly, the research has led to changes in patient care and enabled clinicians to gain research experience and further academic qualifications. The other benefit is that nurse academics have strengthened their working relationship with clinicians and ensured visible research outputs were achieved.

    This study quantifies the possible impacts of urban heat-island countermeasures upon buildings' energy use during summer in Tokyo metropolis. Considering the dependency of the buildings air temperature upon the local urban canopy structure, Tokyo urban canopies were classified in the city-block-scale using the sky-view factor (svf). Then, a multi-scale model system describing the interaction between buildings' energy use and urban meteorological conditions was applied to each classified canopy. In terms of urban warming alleviation and cooling energy saving, simulations suggested that the reduction in the air-conditioning anthropogenic heat could be the most effective measure in office buildings' canopies, and that vegetative fraction increase on the side walls of buildings in residential canopies. Both measures indicated daily and spatially averaged decreases in near-ground summer air temperature of 0.2-1.2{sup o}C. The simulations also suggested these temperature decreases could result in the buildings' cooling energy-savings of 4-40%, indicating remarkable savings in residential canopies. These temperature drops and energy savings tended to increase with the decrease of the svf of urban canopies. (author)

    This is the second volume of Building 2000, a pilot project of the Commission's R and D-programme 'Solar Energy Applications to Buildings' with the purpose of encouraging the adoption of solar architecture in large buildings. In this second rich illustrated volume the results of the design studies illustrating passive solar architecture in buildings in the European Community are presented in particular for the building categories as mentioned in the subtitle. In the first volume, a similar series of studies is presented for the building categories: schools, laboratories and universities, and sports and educational centres. Several Design Support Workshops were organized during the Building 2000 programme during which Building 2000 design teams could directly exchange ideas with the various design advice experts represented at these workshops. In the second part of the Building 2000 final report a summary of a selection of many reports is presented (11 papers), as produced by Design Support experts. Most of the design support activities resulted in changes of the various designs, as have been reported by the design teams in the brochures presented in the first part of this book. It is to be expected that design aids and simulation tools for passive solar options, daylighting concepts, comfort criteria etc., will be utilized more frequently in the future. This will result in a better exchange of information between the actual design practitioners and the European R and D community. This technology transfer will result in buildings with a higher quality with respect to energy and environmental issues

    Strategies to improve energy efficiency in buildings have continuously being improved and becoming more effective as new knowledge on the building behavior and technology continue to develop. Nevertheless, effort to explore for further improvement must continuously undertake to seek more energy efficient and cost effective systems. Artificial Neural Network (ANN) is currently one of the most popular mechanisms to forecast any form of behavior and phenomena. Building thermal behavior can be studied and potential for energy utilization improvement without compromising thermal comfort can be explored using ANN. This paper explores the possibility of monitoring, predicting and forecasting the thermal behavior inside a building space and the optimization of building design. Typical result of experimental data and simulated data is presented. The sample house used adopted various thermal comfort strategies like cross ventilation and space air flow consideration

    Examination of the lessons to be learned from the accident of the Three Mile Island nuclear power plant on 20 March 1979 led the French Safety Authorities and EDF (Electricite de France) to adopt a series of measures intended to improve the performance of the containment of French PWRs, especially in the event of accident. Among the measures adopted, two of them contribute to the upgrading of the containment of nuclear island buildings, by reducing radioactivity constraints inside these buildings and by limiting radioactive releases into the environment. These are: (1) dynamic containment of auxiliary buildings likely to be contaminated following an accident, (2) reinjection back into the reactor building of liquid effluents arising in the auxiliary buildings. In this paper we shall discuss, for each measure, the approach to the problem and describe the arrangements made to arrive at a satisfactory solution [fr
