    There are two main objectives to this publication. The first is to find out the communalities in the experience gained in previous studies and in actual applications of solar technologies in buildings, residential as well as nonresidential. The second objective is to review innovative concepts and products which may have an impact on future developments and applications of solar technologies in buildings. The available information and common lessons were collated and presented in a form which, hopefully, is useful for architects and solar engineers, as well as for teachers of "solar architecture" and students in Architectural Schools. The publication is based mainly on the collection and analysis of relevant information. The information included previous studies in which the performance of solar buildings was evaluated, as well as the personal experience of the Author and the research consultants. The state of the art, as indicated by these studies and personal experience, was summarized and has served as basis for the development of the Design Guidelines. In addition to the summary of the state of the art, as was already applied in solar buildings, an account was given of innovative concepts and products. Such innovations have occurred in the areas of thermal storage by Phase Change Materials (PCM) and in glazing with specialized or changeable properties. Interesting concepts were also developed for light transfer, which may enable to transfer sunlight to the core areas of large multi story nonresidential buildings. These innovations may have a significant impact on future developments of solar technologies and their applications in buildings.

    Full Text Available The article describes the structure and field of standardization ISO / TC 205 “Building environment design”, provides examples of green building technologies. The main purpose of the article is to show the interaction between international ISO / TC 205 “Building environment design” and created in Russia in 2016 the Technical Committee of Standardization № 366 “Green technology of the build environment and green innovative products”. Both of these technical committees promote green building technologies for environment design, thereby deal with the negative impact on the environment and the reasons of global warming. Instead of buildings that attempt to suppress and overcome nature, why not design buildings that integrate with the environment, on every possible level? The international standardization work which ISO/TC 205 “Building environment design” performs seeks, in addition to lowering trade barriers for engineering design, to promote and facilitate the design of high performance buildings: higher performing as economic assets for their owners, higher performing as buildings that provide amenable indoor environment for their occupants, and higher performing with respect to resource utilization and environmental impact.

    The addition of storage technologies such as flow batteries, conventional batteries, and heat storage can improve the economic, as well as environmental attraction of micro-generation systems (e.g., PV or fuel cells with or without CHP) and contribute to enhanced demand response. The interactions among PV, solar thermal, and storage systems can be complex, depending on the tariff structure, load profile, etc. In order to examine the impact of storage technologies on demand response and CO2 emissions, a microgrid's distributed energy resources (DER) adoption problem is formulated as a mixed-integer linear program that can pursue two strategies as its objective function. These two strategies are minimization of its annual energy costs or of its CO2 emissions. The problem is solved for a given test year at representative customer sites, e.g., nursing homes, to obtain not only the optimal investment portfolio, but also the optimal hourly operating schedules for the selected technologies. This paper focuses on analysis of storage technologies in micro-generation optimization on a building level, with example applications in New York State and California. It shows results from a two-year research projectperformed for the U.S. Department of Energy and ongoing work. Contrary to established expectations, our results indicate that PV and electric storage adoption compete rather than supplement each other considering the tariff structure and costs of electricity supply. The work shows that high electricity tariffs during on-peak hours are a significant driver for the adoption of electric storage technologies. To satisfy the site's objective of minimizing energy costs, the batteries have to be charged by grid power during off-peak hours instead of PV during on-peak hours. In contrast, we also show a CO2 minimization strategy where the common assumption that batteries can be charged by PV can be fulfilled at extraordinarily high energy costs for the site.

    Public engagement with science and technology is now widely used in science policy and communication. Touted as a means of enhancing democratic discussion of science and technology, analysis of public engagement with science and technology has shown that it is often weakly tied to scientific governance. In this article, we suggest that the notion of capacity building might be a way of reframing the democratic potential of public engagement with science and technology activities. Drawing on literatures from public policy and administration, we outline how public engagement with science and technology might build citizen capacity, before using the notion of capacity building to develop five principles for the design of public engagement with science and technology. We demonstrate the use of these principles through a discussion of the development and realization of the pilot for a large-scale public engagement with science and technology activity, the Futurescape City Tours, which was carried out in Arizona in 2012.

  9. Modernity in tradition: Reflections on building design and technology in the Asian vernacular

    Full Text Available Vernacular buildings across the globe provide instructive examples of sustainable solutions to building problems. Yet, these solutions are assumed to be inapplicable to modern buildings. Despite some views to the contrary, there continues to be a tendency to consider innovative building technology as the hallmark of modern architecture because tradition is commonly viewed as the antonym of modernity. The problem is addressed by practical exercises and fieldwork studies in the application of vernacular traditions to current problems. This study investigates some aspects of mainstream modernist design solutions and concepts inherent in the vernacular of Asia, particularly that of the Chittagong Hill Tracts (CHT. This work hinges on such ideas and practices as ecological design, modular and incremental design, standardization, and flexible and temporal concepts in the design of spaces. The blurred edges between the traditional and modern technical aspects of building design, as addressed by both vernacular builders and modern architects, are explored.

    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.

    The August 2003 blackout of the northeastern U.S. and CANADA caused great economic losses and inconvenience to New York City and other affected areas. The blackout was a warning to the rest of the world that the ability of conventional power systems to meet growing electricity demand is questionable. Failure of large power systems can lead to serious emergencies. Introduction of on-site generation, renewable energy such as solar and wind power and the effective utilization of exhaust heat is needed, to meet the growing energy demands of the residential and commercial sectors. Additional benefit can be achieved by integrating these distributed technologies into distributed energy resource (DER) systems. This work demonstrates a method for choosing and designing economically optimal DER systems. An additional purpose of this research is to establish a database of energy tariffs, DER technology cost and performance characteristics, and building energy consumption for Japan. This research builds on prior DER studies at the Ernest Orlando Lawrence Berkeley National Laboratory (LBNL) and with their associates in the Consortium for Electric Reliability Technology Solutions (CERTS) and operation, including the development of the microgrid concept, and the DER selection optimization program, the Distributed Energy Resources Customer Adoption Model (DER-CAM). DER-CAM is a tool designed to find the optimal combination of installed equipment and an idealized operating schedule to minimize a site's energy bills, given performance and cost data on available DER technologies, utility tariffs, and site electrical and thermal loads over a test period, usually an historic year. Since hourly electric and thermal energy data are rarely available, they are typically developed by building simulation for each of six end use loads used to model the building: electric-only loads, space heating, space cooling, refrigeration, water heating, and natural-gas-only loads.

  4. Technology Solutions Case Study: Calculating Design Heating Loads for Superinsulated Buildings

    Energy Technology Data Exchange (ETDEWEB)

    2015-08-01

    Designing a superinsulated home has many benefits including improved comfort, reduced exterior noise penetration, lower energy bills, and the ability to withstand power and fuel outages under much more comfortable conditions than a typical home. Extremely low heating and cooling loads equate to much smaller HVAC equipment than conventionally required. Sizing the mechanical system to these much lower loads reduces first costs and the size of the distribution system needed. While these homes aren't necessarily constructed with excessive mass in the form of concrete floors and walls, the amount of insulation and the increase in the thickness of the building envelope can lead to a mass effect, resulting in the structures ability to store much more heat than a code built home. This results in a very low thermal inertia making the building much less sensitive to drastic temperature swings thereby decreasing the peak heating load demand. Alternative methods that take this inertia into account along with solar and internal gains result in smaller more appropriate design loads than those calculated using Manual J version 8. During the winter of 2013/2014, the Consortium for Advanced Residential Buildings team monitored the energy use of three homes in climate zone 6 in an attempt to evaluate the accuracy of two different mechanical system sizing methods for low load homes. Based on the results, it is recommended that internal and solar gains be included and some credit for thermal inertia be used in sizing calculations for superinsulated homes.

    The 1995 annual report discusses laboratory activities in the Building Technology Program. The report is divided into four categories: windows and daylighting, lighting systems, building energy simulation, and advanced building systems. The objective of the Building Technologies program is to assist the U.S. building industry in achieving substantial reductions in building-sector energy use and associated greenhouse gas emissions while improving comfort, amenity, health, and productivity in the building sector. Past efforts have focused on windows and lighting, and on the simulation tools needed to integrate the full range of energy efficiency solutions into achievable, cost-effective design solutions for new and existing buildings. Current research is based on an integrated systems and life-cycle perspective to create cost-effective solutions for more energy-efficient, comfortable, and productive work and living environments. Sixteen subprograms are described in the report.

    Full Text Available The sustainable building design process is driven on the basis of a range of design eco-indicators. Consideration of a multitude of eco-determinants, such as environment, economy, resources, energy consumption and society values in addition to design characteristics and contexts, makes the process of ecological design even more complex. A large number of eco-drivers are extracted from the literature and current design practices. To gain a better insight on eco-design determinants, a survey focusing on the use of eco-design drivers has been conducted with various architects in the UK. The factor analysis method was used to remove redundant data from the survey. Through the factor analysis approach, 115 eco-determinants are grouped into six main clusters. This article presents the process, analysis and findings of this work. The extracted eco-indicators and their associated clusters can be used to improve the process of ecological building design.

    Full Text Available The current building life cycle management system in the Russian Federation is a family of discrete subsystems that exist independently for different building life cycle stages. In this situation building reliability and sustainable functioning are out of the question. The implementation of a united information model (BIM-model intended to describe building entire life cycle will allow to raise the sustainability, but this will happen only if goals and concerns of all participants of the project process are properly coordinated. An important figure of process sustainability is the organizational and technological reliability (OTR that describes the possibility of a system to reach a goal. In case of building life cycle design, the economical efficiency of a building can be considered as the goal. The required technical, ecological, organizational, and other parameters form a complex of constraints that determine the area of allowable values for building functioning. In its broad meaning, OTR may be understood as the probability of receiving an economical effect based on the value of organizational and economical reliability (OER.

  16. "Watts per person" paradigm to design net zero energy buildings: Examining technology interventions and integrating occupant feedback to reduce plug loads in a commercial building

    Science.gov (United States)

    Yagi Kim, Mika

    As building envelopes have improved due to more restrictive energy codes, internal loads have increased largely due to the proliferation of computers, electronics, appliances, imaging and audio visual equipment that continues to grow in commercial buildings. As the dependency on the internet for information and data transfer increases, the electricity demand will pose a challenge to design and operate Net Zero Energy Buildings (NZEBs). Plug Loads (PLs) as a proportion of the building load has become the largest non-regulated building energy load and represents the third highest electricity end-use in California's commercial office buildings, accounting for 23% of the total building electricity consumption (Ecova 2011,2). In the Annual Energy Outlook 2008 (AEO2008), prepared by the Energy Information Administration (EIA) that presents long-term projections of energy supply and demand through 2030 states that office equipment and personal computers are the "fastest growing electrical end uses" in the commercial sector. This thesis entitled "Watts Per Person" Paradigm to Design Net Zero Energy Buildings, measures the implementation of advanced controls and behavioral interventions to study the reduction of PL energy use in the commercial sector. By integrating real world data extracted from an energy efficient commercial building of its energy use, the results produce a new methodology on estimating PL energy use by calculating based on "Watts Per Person" and analyzes computational simulation methods to design NZEBs.

    Antimicrobial resistance has reached globally alarming levels and is becoming a major public health threat. Lack of efficacious antimicrobial resistance surveillance systems was identified as one of the causes of increasing resistance, due to the lag time between new resistances and alerts to care providers. Several initiatives to track drug resistance evolution have been developed. However, no effective real-time and source-independent antimicrobial resistance monitoring system is available publicly. To design and implement an architecture that can provide real-time and source-independent antimicrobial resistance monitoring to support transnational resistance surveillance. In particular, we investigated the use of a Semantic Web-based model to foster integration and interoperability of interinstitutional and cross-border microbiology laboratory databases. Following the agile software development methodology, we derived the main requirements needed for effective antimicrobial resistance monitoring, from which we proposed a decentralized monitoring architecture based on the Semantic Web stack. The architecture uses an ontology-driven approach to promote the integration of a network of sentinel hospitals or laboratories. Local databases are wrapped into semantic data repositories that automatically expose local computing-formalized laboratory information in the Web. A central source mediator, based on local reasoning, coordinates the access to the semantic end points. On the user side, a user-friendly Web interface provides access and graphical visualization to the integrated views. We designed and implemented the online Antimicrobial Resistance Trend Monitoring System (ARTEMIS) in a pilot network of seven European health care institutions sharing 70+ million triples of information about drug resistance and consumption. Evaluation of the computing performance of the mediator demonstrated that, on average, query response time was a few seconds (mean 4.3, SD 0.1 × 10

    Mining industry provides building materials for construction. Civil engineers have settled the quality parameters for construction materials. When we produce high quality building materials from carbonate rock (limestone, dolostone), then the estimated waste share is 25% to 30%, depending on crushing principles and rock quality. The challenge is to find suitable technology for waste recovery. During international mining waste related cooperation project MIN-NOVATION (www.min-novation.eu), partners mapped possibilities for waste recovery in mining industry and pointed out good examples and case studies. One example from Estonia showed that when we produce limestone aggregate, then we produce up to 30% waste material (fines with size 0-4mm). This waste material we can see as secondary raw material for building materials. Recovery technology for this fine grained material has been achieved with CDE separation plant. During the process the plant washes out minus 63 micron material from the limestone fines. This technology allows us to use 92% of all limestone reserves. By-product from 63 microns to 4 mm we can use as filler in concrete or as fine limestone aggregate for building or building materials. MIN-NOVATION project partners also established four pilot stations to study other mineral waste recovery technologies and solutions. Main aims on this research are to find the technology for recovery of mineral wastes and usage for new by-products from mineral mining waste. Before industrial production, testing period or case studies are needed. This research is part of the study of Sustainable and environmentally acceptable Oil shale mining No. 3.2.0501.11-0025 http://mi.ttu.ee/etp and the project B36 Extraction and processing of rock with selective methods - http://mi.ttu.ee/separation; http://mi.ttu.ee/miningwaste/

    Energy Technology Data Exchange (ETDEWEB)

    2015-08-01

    Designing a superinsulated home has many benefits including improved comfort, reduced exterior noise penetration, lower energy bills, and the ability to withstand power and fuel outages under much more comfortable conditions than a typical home. Extremely low heating and cooling loads equate to much smaller HVAC equipment than conventionally required. Sizing the mechanical system to these much lower loads reduces first costs and the size of the distribution system needed. While these homes aren't necessarily constructed with excessive mass in the form of concrete floors and walls, the amount of insulation and the increase in the thickness of the building envelope can lead to a mass effect, resulting in the structures ability to store much more heat than a code built home. This results in a very low thermal inertia making the building much less sensitive to drastic temperature swings thereby decreasing the peak heating load demand. Alternative methods that take this inertia into account along with solar and internal gains result in smaller more appropriate design loads than those calculated using Manual J version 8. During the winter of 2013/2014, CARB monitored the energy use of three homes in climate zone 6 in an attempt to evaluate the accuracy of two different mechanical system sizing methods for low load homes. Based on the results, it is recommended that internal and solar gains be included and some credit for thermal inertia be used in sizing calculations for superinsulated homes.

    This study aimed to construct an on-site eco-sewerage system for modern office buildings in urban area based on combined innovative technologies of vacuum and source-separation. Results showed that source-separated grey water had low concentrations of pollutants, which helped the reuse of grey water. However, the system had a low separation efficiency between the yellow water and the brown water, which was caused by the plug problem in the urine collection from the urine-diverting toilets. During the storage of yellow water for liquid fertilizer production, nearly all urea nitrogen transferred to ammonium nitrogen and about 2/3 phosphorus was lost because of the struvite precipitation. Total bacteria and coliforms increased first in the storage, but then decreased to low concentrations. The anaerobic/anoxic/aerobic MBR had high elimination rates of COD, ammonium nitrogen and total nitrogen of the brown water, which were 94.2%, 98.1% and 95.1%, respectively. However, the effluent still had high contents of colority, nitrate and phosphorus, which affected the application of the effluent for flushing water. Even though, the effluent might be used as dilution water for the yellow water fertilizer. Based on the results and the assumption of an ideal operation of the vacuum source-separation system, a future plan for on-site eco-sewerage system of modern office buildings was constructed. Its sustainability was validated by the analysis of the substances flow of water and nutrients.

    As the dawn of the twenty-first century approaches, the current pattern of unsustainable, inequitable and unstable asymmetric demographic and economic growth has forced many segments of society to come together in facing a critical challenge: how can societies across the world meet their current basic human needs, aspirations and desires, without compromising the ability of future generations to meet their own needs? At the core of this challenge is the question: how can the human race maintain in perpetuity a healthy, physically attractive and biologically productive environment. The development path that we have been taking, in the past few centuries, has been ultimately detrimental to the health of our surrounding ecological context. We are consuming an increasing share of the natural resources available to use on this planet, and we are creating sufficiently large amounts of waste and pollution such that the earth can no longer assimilate our wastes and recover from the negative impacts. This is a result of a growing population as well as new technologies which make it easier for use to access natural resources and also require the consumption of more resources. Unsustainable technology has been the result of linear rather than cyclic thinking. The paradigm shift from linear to cyclic thinking in technological design is the crux of the shift from unsustainability to sustainability. This paper discusses the implications for the building design and construction industries. Strategies, technologies, and opportunities are presented to improve the sustainability of the built environment.

    Full Text Available Growing attention is being paid to indoor air quality as one of the main health and well-being factors. The indoor research is concerned mostly to indoor air chemicals within indoor engineering related to building design. The providing good indoor air quality can be achieved effectively by avoiding or reducing indoor air pollution sources and by selecting low-polluting building materials, both being low-cost and energyefficient solutions. On the base of the last large experimental monitoring results, it was possible to know the level of selected indoor chemicals occurrence, rank them as well as to predict the tendencies of occurrence and establish the priorities for the future. There has been very limited attention to rigorous analysis of buildings actual environmental impacts to date. Healthy/green/sustainable building practices are typically applied in unsystematic and inconsistent ways often without resolution of inherent conflicts between and among such practices. Designers, products manufacturers, constructors, and owners declare their buildings and the applied technologies to be beneficial to the environment without validating those claims.

  6. Design Buildings Optimally: A Lifecycle Assessment Approach

    KAUST Repository

    Hosny, Ossama

    2013-01-01

    This paper structures a generic framework to support optimum design for multi-buildings in desert environment. The framework is targeting an environmental friendly design with minimum lifecycle cost, using Genetic Algorithms (Gas). GAs function through a set of success measures which evaluates the design, formulates a proper objective, and reflects possible tangible/intangible constraints. The framework optimizes the design and categorizes it under a certain environmental category at minimum Life Cycle Cost (LCC). It consists of three main modules: (1) a custom Building InformationModel (BIM) for desert buildings with a compatibility checker as a central interactive database; (2) a system evaluator module to evaluate the proposed success measures for the design; and (3) a GAs optimization module to ensure optimum design. The framework functions through three levels: the building components, integrated building, and multi-building levels. At the component level the design team should be able to select components in a designed sequence to ensure compatibility among various components, while at the building level; the team can relatively locate and orient each individual building. Finally, at the multi-building (compound) level the whole design can be evaluated using success measures of natural light, site capacity, shading impact on natural lighting, thermal change, visual access and energy saving. The framework through genetic algorithms optimizes the design by determining proper types of building components and relative buildings locations and orientations which ensure categorizing the design under a specific category or meet certain preferences at minimum lifecycle cost.

  7. Revisit of Energy Use and Technologies of High Performance Buildings

    Energy Technology Data Exchange (ETDEWEB)

    Li, Cheng; Hong, Tianzhen

    2014-03-30

    Energy consumed by buildings accounts for one third of the world?s total primary energy use. Associated with the conscious of energy savings in buildings, High Performance Buildings (HPBs) has surged across the world, with wide promotion and adoption of various performance rating and certification systems. It is valuable to look into the actual energy performance of HPBs and to understand their influencing factors. To shed some light on this topic, this paper conducted a series of portfolio analysis based on a database of 51 high performance office buildings across the world. Analyses showed that the actual site Energy Use Intensity (EUI) of the 51 buildings varied by a factor of up to 11, indicating a large scale of variation of the actual energy performance of the current HPBs. Further analysis of the correlation between EUI and climate elucidated ubiquitous phenomenon of EUI scatter throughout all climate zones, implying that the weather is not a decisive factor, although important, for the actual energy consumption of an individual building. On the building size via EUI, analysis disclosed that smaller buildings have a tendency to achieving lower energy use. Even so, the correlation is not absolute since some large buildings demonstrated low energy use while some small buildings performed opposite. Concerning the technologies, statistics indicated that the application of some technologies had correlations with some specific building size and climate characteristic. However, it was still hard to pinpoint a set of technologies which was directly correlative with a group of low EUI buildings. It is concluded that no a single factor essentially determines the actual energy performance of HPBs. To deliver energy-efficient buildings, an integrated design taking account of climate, technology, occupant behavior as well as operation and maintenance should be implemented.

    Full Text Available This research is to recognise the function of Building Information Modelling (BIM in design optimization for irregular shaped buildings. The study focuses on a conceptual irregular shaped “twisted” building design similar to some existing sculpture-like architectures. Form and function are the two most important aspects of new buildings, which are becoming more sophisticated as parts of equally sophisticated “systems” that we are living in. Nowadays, it is common to have irregular shaped or sculpture-like buildings which are very different when compared to regular buildings. Construction industry stakeholders are facing stiff challenges in many aspects such as buildability, cost effectiveness, delivery time and facility management when dealing with irregular shaped building projects. Building Information Modelling (BIM is being utilized to enable architects, engineers and constructors to gain improved visualization for irregular shaped buildings; this has a purpose of identifying critical issues before initiating physical construction work. In this study, three variations of design options differing in rotating angle: 30 degrees, 60 degrees and 90 degrees are created to conduct quantifiable comparisons. Discussions are focused on three major aspects including structural planning, usable building space, and structural constructability. This research concludes that Building Information Modelling is instrumental in facilitating design optimization for irregular shaped building. In the process of comparing different design variations, instead of just giving “yes or no” type of response, stakeholders can now easily visualize, evaluate and decide to achieve the right balance based on their own criteria. Therefore, construction project stakeholders are empowered with superior evaluation and decision making capability.

    The term "smart city" defines the new urban environment, one that is designed for performance through information and communication technologies. Given that the majority of people across the world will live in urban environments within the next few decades, it's not surprising that massive effort and investment is being placed into efforts to develop strategies and plans for achieving "smart" urban growth. Building Smart Cities: Analytics, ICT, and Design Thinking explains the technology and a methodology known as design thinking for building smart cities. Information and communications technologies form the backbone of smart cities. A comprehensive and robust data analytics program enables the right choices to be made in building these cities. Design thinking helps to create smart cities that are both livable and able to evolve. This book examines all of these components in the context of smart city development and shows how to use them in an integrated manner. Using the principles of design thinking to refr...

    2002-07-01

    The terms 'sustainable architecture', 'green building' and 'ecological design' have emerged, along with a host of similar permutations, in recent practice as environmentally friendly modes of design, construction and operation geared towards producing healthy enduring communities. However, the terms are still vague and lead to much ambiguity in their implementation. This paper consolidates the current foci of sustainable architecture through a review of several projects and institutional guidelines that are geared towards achieving sustainability in the built environment. A contemporary checklist of desirable design strategies and building practices for a green building is presented. Consideration is given to attempts at ranking the importance of these strategies. While it is concluded that the implementation of green building design cannot be prescriptive, the checklist is intended to be an awareness-raising tool that provides the foundation for greater innovation in the designer's approach to building projects. The concept of a 'healing building' is proposed as perhaps the next level of sustainable architecture. (author)

  8. Potential for energy technologies in residential and commercial buildings

    Glesk, M.M.

    1979-11-01

    The residential-commercial energy technology model was developed as a planning tool for policy analysis in the residential and commercial building sectors. The model and its procedures represent a detailed approach to estimating the future acceptance of energy-using technologies both in new construction and for retrofit into existing buildings. The model organizes into an analytical framework all relevant information and data on building energy technology, building markets, and government policy, and it allows for easy identification of the relative importance of key assumptions. The outputs include estimates of the degree of penetration of the various building energy technologies, the levels of energy use savings associated with them, and their costs - both private and government. The model was designed to estimate the annual energy savings associated with new technologies compared with continued use of conventional technology at 1975 levels. The amount of energy used under 1975 technology conditions is referred to as the reference case energy use. For analytical purposes the technologies were consolidated into ten groupings: electric and gas heat pumps; conservation categories I, II, and III; solar thermal (hot water, heating, and cooling); photovoltaics, and wind systems. These groupings clearly do not allow an assessment of the potential for individual technologies, but they do allow a reasonable comparison of their roles in the R/C sector. Assumptions were made regarding the technical and economic performances of the technologies over the period of the analysis. In addition, the study assessed the non-financial characteristics of the technologies - aesthetics, maintenance complexity, reliability, etc. - that will also influence their market acceptability.

    A Technology Roadmap (TRM) is a process tool developed to help Canadian industries identify and address the technology challenges in the future. This report presented the findings from an evaluation of the Technology Roadmap for Intelligent Building Technologies (IBT TRM) that began in 1999 and was released in 2002. The IBT TRM was a collaborative research project between industry and 5 Canadian federal government organizations. The project was managed by the Continental Automated Buildings Association (CABA). The purpose of the TRM was to clarify the challenges and opportunities in the general area of intelligent building technologies. The lack of understanding of IBTs by the construction industry was identified by participants as a significant national issue because it was the major obstacle to the adoption of emerging technologies. New initiatives launched by the IBT TRM as a consequence of the evaluation include the creation of the Intelligent and Integrated Buildings Council (IIBC) sub-committee of CABA to act on the recommendations of the TRM; and planning by CABA for a new TRM to focus on residential rather than commercial buildings. It was also noted that a valuable network of contracts was created during the evaluation process. Various promotional initiatives were reviewed. It was concluded that Industry Canada should continue to play a continued role in the TRM, particularly in the area of fostering and facilitating the development of regulations and standards; further leveraging the expertise of federal research facilities; encouraging international trade efforts; and exploring the applications of intelligent building technologies to other industries. It was suggested that TRMs support the sector's strategic objectives related to the development, adaptation, diffusion and use of sustainable technologies.

  12. A Semantics-Rich Information Technology Architecture for Smart Buildings

    Directory of Open Access Journals (Sweden)

    Dario Bonino

    2014-11-01

    Full Text Available The design of smart homes, buildings and environments currently suffers from a low maturity of available methodologies and tools. Technologies, devices and protocols strongly bias the design process towards vertical integration, and more flexible solutions based on separation of design concerns are seldom applied. As a result, the current landscape of smart environments is mostly populated by defectively designed solutions where application requirements (e.g., end-user functionality are too often mixed and intertwined with technical requirements (e.g., managing the network of devices. A mature and effective design process must, instead, rely on a clear separation between the application layer and the underlying enabling technologies, to enable effective design reuse. The role of smart gateways is to enable this separation of concerns and to provide an abstracted view of available automation technology to higher software layers. This paper presents a blueprint for the information technology (IT architecture of smart buildings that builds on top of established software engineering practices, such as model-driven development and semantic representation, and that avoids many pitfalls inherent in legacy approaches. The paper will also present a representative use case where the approach has been applied and the corresponding modeling and software tools.

  18. Building Technological Capability within Satellite Programs in Developing Countries

    Science.gov (United States)

    Wood, Danielle Renee

    Global participation in space activity is growing as satellite technology matures and spreads. Countries in Africa, Asia and Latin America are creating or reinvigorating national satellite programs. These countries are building local capability in space through technological learning. They sometimes pursue this via collaborative satellite development projects with foreign firms that provide training. This phenomenon of collaborative satellite development projects is poorly understood by researchers of technological learning and technology transfer. The approach has potential to facilitate learning, but there are also challenges due to misaligned incentives and the tacit nature of the technology. Perspectives from literature on Technological Learning, Technology Transfer, Complex Product Systems and Product Delivery provide useful but incomplete insight for decision makers in such projects. This work seeks a deeper understanding of capability building through collaborative technology projects by conceiving of the projects as complex, socio-technical systems with architectures. The architecture of a system is the assignment of form to execute a function along a series of dimensions. The research questions explore the architecture of collaborative satellite projects, the nature of capability building during such projects, and the relationship between architecture and capability building. The research design uses inductive, exploratory case studies to investigate six collaborative satellite development projects. Data collection harnesses international field work driven by interviews, observation, and documents. The data analysis develops structured narratives, architectural comparison and capability building assessment. The architectural comparison reveals substantial variation in project implementation, especially in the areas of project initiation, technical specifications of the satellite, training approaches and the supplier selection process.

    Energy Technology Data Exchange (ETDEWEB)

    Sawers, J. [Reid Crowther and Partners Ltd., Calgary, AB (Canada)

    1998-12-01

    A proposed green building technology evaluation model is described. The model was developed as result of the inability of traditional evaluation techniques such as pay-back period, net present value and life cycle cost, to deal effectively with the intangible benefits of green technologies. Unlike traditional tools which are primarily financial in nature, the proposed model is based on a model developed in the Information Technology (IT) industry. It extends the concept of `benefit` to include a wide range of factors that affect a system`s business value. It also extends the concept of `cost` to include an evaluation of risk. The model considers nine criteria divided into two groups: business criteria and technology criteria. Business criteria encompass economic impact, strategic alignment, competitive advantage, improved management information, competitive risk, and organizational risk. The technological criteria comprise strategic architecture, definition uncertainty, and infrastructure risk. Assignment of weights to each of these criteria is somewhat subjective, but subjectivity can be overcome by the consistent use of good judgment. The green building technologies model draws on both the IT model and the value management concept (i.e. `value to a client within a particular context`). The model provides for the use of a value hierarchy to establish and weigh decision criteria; it expands the definition of project `costs` and `benefits`, and provides a decision matrix and sensitivity analysis. 6 refs., 4 figs.

    Building fire is a risky activity that can lead to disaster and massive destruction. The management and disposal of building fire has always attracted much interest from researchers. Integrated Virtual Geographic Environment (VGE) is a good choice for building fire safety management and emergency decisions, in which a more real and rich fire process can be computed and obtained dynamically, and the results of fire simulations and analyses can be much more accurate as well. To modelling building fire scene with VGE, the application requirements and modelling objective of building fire scene were analysed in this paper. Then, the four core elements of modelling building fire scene (the building space environment, the fire event, the indoor Fire Extinguishing System (FES) and the indoor crowd) were implemented, and the relationship between the elements was discussed also. Finally, with the theory and framework of VGE, the technology of building fire scene system with VGE was designed within the data environment, the model environment, the expression environment, and the collaborative environment as well.

    Full Text Available Engineering design is considered an effective means for developing engineering technical skills. Normally, engineering design is conducted in teams and is a collaborative open-ended approach under constraints. This nature of engineering design involves engagement of several interpersonal, cognitive, and management skills or competencies such as teamwork, communications, decision making, problem solving, etc. While modern engineers are supposed to be technically competent, they need to posses a wide set of interpersonal, cognitive, and management competencies to function effectively in the workplace. Increasingly there has been more deployment of engineering design competitions (EDCs in engineering education to address some gaps in current curricula system. In this study, the impact of a complex engineering design competition on developing 21st century competencies of engineering and technology talent is investigated. A mix of quantitative and qualitative methods in the approach to self-reporting perceptions were utilized. Data was collected through interviews from students and faculty, and through surveys from students. Triangulating quantitative and qualitative data from students and faculty indicate that the investigated EDC have positive impact on a large set of 21st century engineering and technology competencies, this has been consistent across groups of students from the EU, Middle East, and Asia, as well as across genders. This is one of the few available investigations that sheds light in further depth on the impact of engineering design on non-technical skills.

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.

    QUBIC is an instrument aiming at measuring the B mode polarisation anisotropies at medium scales angular scales (30-200 multipoles). The search for the primordial CMB B-mode polarization signal is challenging, because of many difficulties: smallness of the expected signal, instrumental systematics that could possibly induce polarization leakage from the large E signal into B, brighter than anticipated polarized foregrounds (dust) reducing to zero the initial hope of finding sky regions clean enough to have a direct primordial B-modes observation. The QUBIC instrument is designed to address all aspects of this challenge with a novel kind of instrument, a Bolometric Interferometer, combining the background-limited sensitivity of Transition-Edge-Sensors and the control of systematics allowed by the observation of interference fringe patterns, while operating at two frequencies to disentangle polarized foregrounds from primordial B mode polarization. Its characteristics are described in details in this Technologi...

    Design flaws and faulty commissioning can create imbalances in heat transfer and distribution in buildings. The design of the hydronic side of HVAC installations in buildings is in practice often limited to only the full load situation. However, installations most frequently operate in part load situations. This paper discussed a method of designing hydronic circuits for heating which considered full load and part load scenarios. The model was then validated by a simulation tool. Both the tool and the method were based on a modular approach, starting with the heat demands required by the various functions and locations in the building. Common design problems were reviewed, and an overview of the process in designing, commissioning and using a hydronic system was presented. A modular design method for a hydronic system was presented, which enabled users to design the system so that all user modules can be controlled in a decoupled manner, guaranteeing the required full load. The software tool consisted of several parts: a main application for the user interface; and a central project database and information retrieval system. An analysis module monitored design behavior. A library of modules was available within the program, as well as a graphical interface. Based on the outcome of calculation results, users can make changes in design and then restart the evaluation. It was anticipated that the tool will be coupled to a building simulation tool which will allow for the calculation of the dynamic demands of a building and provide realistic part-load information. The algorithm for solving the non linear equations of pressure versus flow was discussed. Equations were solved on 2 levels, and the solving process consisted of several repeated steps. The analysis module consisted of an expert system containing several rules describing the desired behavior of hydronic systems. It was noted that the rules were derived from, and compliant with compliance standards. 11 refs

    Scaling-up capabilities for the design, build, and test of synthetic biology constructs holds great promise for the development of new applications in fuels, chemical production, or cellular-behavior engineering. Construct design is an essential component in this process; however, not every designed DNA sequence can be readily manufactured, even using state-of-the-art DNA synthesis methods. Current biological computer-aided design and manufacture tools (bioCAD/CAM) do not adequately consider the limitations of DNA synthesis technologies when generating their outputs. Designed sequences that violate DNA synthesis constraints may require substantial sequence redesign or lead to price-premiums and temporal delays, which adversely impact the efficiency of the DNA manufacturing process. We have developed a suite of build-optimization software tools (BOOST) to streamline the design-build transition in synthetic biology engineering workflows. BOOST incorporates knowledge of DNA synthesis success determinants into the design process to output ready-to-build sequences, preempting the need for sequence redesign. The BOOST web application is available at https://boost.jgi.doe.gov and its Application Program Interfaces (API) enable integration into automated, customized DNA design processes. The herein presented results highlight the effectiveness of BOOST in reducing DNA synthesis costs and timelines.

Nowadays the use of renewable energy for space heating became one of the top priorities in modern building design. The active and passive solar energy as well as heat pumps are widely used nowadays. However, such technologies have a limitation in cold climates and often are not able to cover maximal heating loads. This paper is devoted to analysis of influence of building envelope's properties and outdoor air parameters on indoor air thermodynamic parameters stability in winter time. It presents analysis of thermal mass impact on building energy performance and indoor air parameter stability in cold climate. The results show that the thermal mass of building envelope is able to cover extreme winter temperatures as well as in case of emergency heat supply break.

    B&W Y-12 is committed to modernizing the Y-12 complex to meet future needs with a sustainable and responsive infrastructure and to integrating sustainability principles and practices into Y-12 work (Y72-001, B&W Y-12 Environmental, Safety and Health Policy). This commitment to sustainability and specifically sustainable design of buildings is also incorporated into Presidential Executive Orders (EO), DOE Orders (DOE O), and goals. Sustainable building design is an approach to design, construct, and operate facilities in an efficient and environmentally sound manner that will produce a healthful, resource-efficient and productive working environment that is inherently protective of the environment. The DOE has established the following 5 Guiding Principles for High Performance Sustainable Building (HPSB), and has issued directives that require Y-12 to incorporate the principles and a number of supporting specific practices and techniques into building design, construction and renovation projects: (1) Employ Integrated Design Principles; (2) Optimize Energy Performance; (3) Protect and Conserve Water; (4) Enhance Indoor Environmental Quality; and (5) Reduce Environmental Impact of Materials. The purpose of this document is to present the required sustainable building principles, practices and techniques, summarize the key drivers for incorporating them into Y-12 projects, and present additional recommendations and resources that can be used to support sustainable buildings to enhance the environmental and economic performance of the Y-12 Complex.

    2012-07-01

    This thesis describes the outcome of the PhD project Integrated energy design of the building envelope carried out through a combination of scientific dissemination reported through peer-reviewed journals and a wide range of affiliated projects involved in at an architectural firm. The research project analysed how the implementation of technical knowledge early in the building design process can quantify the effect of a building's facades on its energy efficiency and indoor climate and thereby facilitate a more qualified design development. The project was structured in the following way: 1) the importance of integrating knowledge in the early stages of design, and how it can be done; 2) understanding the facade's typology; and 3) the complex notion of comfort. The project touched not only on the technical capabilities and requirements governing facade design, but also the process by which it takes place. This was done by applying the methodology of Integrated Energy Design (IED) and analysing its applicability in the design of facades. A major part of the project was an actual engagement in the architectural process to test out incorporating a consciousness about energy and comfort as part of a more holistic performance evaluation. The research project illustrates the great potential in taking passive properties into account through a geometrical optimisation inherent in the development of the architectural concept. It demonstrates that integration of technical knowledge at the early stages of design not only can qualify the geometrical processing, but also facilitate the design development of the facade. Thereby a more holistic performance optimisation can be obtained through parameters such as overall facade geometry and orientation, functional organisation, room height and depth, facade layout, window geometry and transparency, design of the window aperture, etc. Through the wide range of affiliated project involved in at the architectural firm over

    Full Text Available The review analyses the language of the Manual for Building Designers and Constructors (2009. It identifies and scrutinizes mistakes of lexis, syntax, and style, since such mistakes are the most common in the publication analysed. A closer look to this manual was encouraged by the survey carried out in 2010 that interviewed students of the VGTU Faculty of Construction and employees in the construction sector. The said survey results showed that the Manual for Building Designers and Constructors is one of the most popular publications both among the students of the Construction faculty and construction sector employees. The current review attempts to draw the attention of editors and scien- tific authors to the necessity to comply with codification, since scientific literature written in the correct language, firstly, encourages pedagogues to abandon the practice of learning from one’s mistakes, and, secondly, it contributes to the formation of the skills of fluent and normative usage of language.

    The generative modeling paradigm is a shift from static models to flexible models. It describes a modeling process using functions, methods and operators. The result is an algorithmic description of the construction process. Each evaluation of such an algorithm creates a model instance, which depends on its input parameters (width, height, volume, roof angle, orientation, location). These values are normally chosen according to aesthetic aspects and style. In this study, the model's parameters are automatically generated according to an objective function. A generative model can be optimized according to its parameters, in this way, the best solution for a constrained problem is determined. Besides the establishment of an overall framework design, this work consists on the identification of different building shapes and their main parameters, the creation of an algorithmic description for these main shapes and the formulation of the objective function, respecting a building's energy consumption (solar energy, heating and insulation). Additionally, the conception of an optimization pipeline, combining an energy calculation tool with a geometric scripting engine is presented. The methods developed leads to an automated and optimized 3D shape generation for the projected building (based on the desired conditions and according to specific constrains). The approach proposed will help in the construction of real buildings that account for less energy consumption and for a more sustainable world.

    Wood, Danielle; Weigel, Annalisa

    2011-12-01

    This paper explores the process of building technological capability in government-led satellite programs within developing countries. The key message is that these satellite programs can learn useful lessons from literature in the international development community. These lessons are relevant to emerging satellite programs that leverage international partnerships in order to establish local capability to design, build and operate satellites. Countries with such programs include Algeria, Nigeria, Turkey, Malaysia and the United Arab Emirates. The paper first provides background knowledge about space activity in developing countries, and then explores the nuances of the lessons coming from the international development literature. Developing countries are concerned with satellite technology because satellites provide useful services in the areas of earth observation, communication, navigation and science. Most developing countries access satellite services through indirect means such as sharing data with foreign organizations. More countries, however, are seeking opportunities to develop satellite technology locally. There are objective, technically driven motivations for developing countries to invest in satellite technology, despite rich debate on this topic. The paper provides a framework to understand technical motivations for investment in satellite services, hardware, expertise and infrastructure in both short and long term. If a country decides to pursue such investments they face a common set of strategic decisions at the levels of their satellite program, their national context and their international relationships. Analysis of past projects shows that countries have chosen diverse strategies to address these strategic decisions and grow in technological capability. What is similar about the historical examples is that many countries choose to leverage international partnerships as part of their growth process. There are also historical examples from

    The major focus world over is on constructing environment friendly buildings. Buildings symbolize uncontrolled consumption of energy and natural resources and also have negative environmental impact. In India, the residential and commercial sector consumes 30 % of the total electricity usage of the country and a major portion of this is used in buildings. Designing and developing new buildings based on the energy efficiency concept and applying retrofit options to the existing buildings could improve the energy use in the building sector. This paper studies an existing building, Central Library of Indian Institute of Technology Roorkee, and recommends retrofit options for sustainable aspects such as site planning, energy and water use, materials and resources and indoor environment quality. The results of this study can be utilized for green retrofits of the other buildings in the campus.

    2008-03-31

    When new technologies are installed in a building, it is difficult to know how various systems will interact and if the building will perform as well as expected. A widely used technique to verify and quantify the actual energy savings from the energy-efficient features in high-performance buildings is to use the calibrated energy simulation approach. Maverick Gardens Mid-Rise A is a six-story apartment building located in East Boston, Massachusetts. The building was designed and constructed to meet the ENERGY STAR Homes Program rating and the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) certification. During the design phase, DOE-2.1E energy models for both budget building design and proposed building design were developed by the design team to demonstrate energy savings potential from various energy efficient technologies installed in this high-performance building. When comparing the energy use predicted by the proposed design energy model with utility bills, the design team observed that this building’s actual energy consumption was about one-third of what was estimated from the proposed design model, and therefore requested help from the authors through the U.S. Department of Energy’s Rebuild America Program to calibrate the proposed design energy model. This paper describes the energy simulation calibration approach using short-term metering data and utility bills. Details of the analysis, calibration results and the actual building energy performance are presented. This study also discusses lessons learned during the simulation calibration process and demonstrates the importance of collaboration among design professionals throughout the design, building, and commissioning process, as a way to ensure that high-performing building goals are met.

    The object of this project is to develop numerical tools based on stochastic methods, issued from the theory of probability. Two objectives have been identified: I. The development of stochastic simulation techniques for thermal design and analysis of passive solar systems and buildings; II. The development of strategies for predictive controllers which can account for the stochastic behaviour of the weather and the occupants of buildings. The advantage of the stochastic approach is to treat the weather evolution and occupants behaviour by their probabilities. Previously to this work, an important effort was made towards the development of a stochastic approach to numerical simulations of passive solar systems. A smaller project has also treated the application of stochastic methods to predictive building thermal control. Encouraging results were obtained. They gave however rise to questions studied within the framework of this project: Design and analysis (hybrid dynamic simulation, Markovian stochastic simulation), predictive control. Two different institutions of the Swiss Federal Institute of Technology in Lausanne collaborate in this project: The 'Solar Energy and Building Physics Laboratory (LESO-PB)' in the Physics Department and the 'Chair of Operations Research' in the Mathematics Department. This document is a synthesis report of the work carried out within the project 'Application des methodes stochastiques: dimensionnement et regulation (Phase I)'.

    BETTER Capstone supported 29 student project teams consisting of 155 students over two years in developing transformative building energy efficiency technologies through a capstone design experience. Capstone is the culmination of an undergraduate student’s engineering education. Interdisciplinary teams of students spent a semester designing and prototyping a technological solution for a variety building energy efficiency problems. During this experience students utilized the full design process, including the manufacturing and testing of a prototype solution, as well as publically demonstrating the solution at the Capstone Design Expo. As part of this project, students explored modern manufacturing techniques and gained hands-on experience with these techniques to produce their prototype technologies. This research added to the understanding of the challenges within building technology education and engagement with industry. One goal of the project was to help break the chicken-and-egg problem with getting students to engage more deeply with the building technology industry. It was learned however that this industry is less interested in trying innovative new concept but rather interested in hiring graduates for existing conventional building efforts. While none of the projects yielded commercial success, much individual student growth and learning was accomplished, which is a long-term benefit to the public at large.

    Accelerating the adoption of new and existing cost-effective technologies has significant potential to reduce the energy consumed in US buildings. This report presents key results of an interlaboratory technology transfer planning effort in support of the US Department of Energy's Office of Building Technologies (OBT). A guiding assumption for planning was that OBT's R D program should forge linkages with existing programs whose goals involved enhancing energy efficiency in buildings. An ad hoc Technology Transfer Advisory Group reviewed the existing analysis and technology transfer program, brainstormed technology transfer approaches, interviewed DOE program managers, identified applicable research results, and developed a framework that management could use in deciding on the best investments of technology transfer resources. Representatives of 22 organizations were interviewed on their views of the potential for transferring energy efficiency technologies through active linking with OBT. The report describes these programs and interview results; outlines OBT tools, technologies, and practices to be transferred; defines OBT audiences; identifies technology transfer functions and presents a framework devised using functions and audiences; presents some 60 example technology transfer activities; and documents the Advisory Group's recommendations. 37 refs., 3 figs., 12 tabs.

    The rapid growth of energy use, worldwide, has raised concerns over problems of energy supply, energy sustainability and exhaustion of energy resources. While most of the developed countries are implementing building energy standard rapidly to reduce building energy consumption and moving aggressively to achieve sustainable energy efficient building; the position of developing countries respect to energy standard implementation for this purpose is either poorly documented or not documented at all. Presently, there exists a gap between existing building designs and the increasing demand for sustainable energy efficient building design in developing countries. In that respect, this paper investigates the implementation status of building energy standards in developing countries and its implications for sustainable energy efficient designs in building. The present implementation status of building energy standard in 60 developing countries around the world, were analyzed using online survey. Hence, this study revealed the present implementation status of building energy standards in developing countries, implications for sustainable energy efficient designs in building and how building energy standards can be used to fill the gap between existing building designs and increasing demand for sustainable energy efficient building.

  5. Airborne infections and modern building technology

    Energy Technology Data Exchange (ETDEWEB)

    LaForce, F.M.

    1986-01-01

    Over the last 30 yr an increased appreciation of the importance of airborne infection has evolved. The concept of droplet nuclei, infectious particles from 0.5 to 3 ..mu.. which stay suspended in air for long periods of time, has been accepted as an important determinant of infectivity. Important airborne pathogens in modern buildings include legionella pneumophila, Aspergillus sp., thermophilic actinomycetes, Mycobacterium tuberculosis, measles, varicella and rubella. Perhaps, the most important microbiologic threat to most buildings is L. pneumophila. This organism can multiply in water cooling systems and contaminate effluent air which can be drawn into a building and efficiently circulated throughout by existing ventilation systems. Hospitals are a special problem because of the concentration of immunosuppressed patients who are uniquely susceptible to airborne diseases such as aspergillosis, and the likelihood that patients ill from diseases that can be spread via the airborne route will be concentrated. Humidifiers are yet another problem and have been shown to be important in several outbreaks of allergic alveolitis and legionellosis. Control of airborne infections is largely an effort at identifying and controlling reservoirs of infection. This includes regular biocide treatment of cooling towers and evaporative condensers and identification and isolation of patients with diseases that may be spread via the airborne route.

    1997-03-01

    In Japan seismic design methodology of nuclear power plant (NPP) structures has been established as introduced in the previous session. And yet efforts have been continued to date to upgrade the methodology, because of conservative nature given to the methodology in regard to unknown phenomena and technically-limited modeling involved in design analyses. The conservative nature tends to produce excessive safety margins, and inevitably send NPP construction cost up. Moreover, excessive seismic design can increase the burden on normal plant operation, though not necessarily contributing to overall plant safety. Therefore, seismic engineering has put to many tests and simulation analyses in hopes to rationalize seismic design and enhance reliability of seismic safety of NPPs. In this paper, we describe some studies on structural seismic design of NPP underway as part of Japan`s effort to upgrade existing seismic design methodology. Most studies described here are carried out by NUPEC (Nuclear Power Engineering Company) funded by MITI (the Ministry of International Trade and Industry Japan), though, similar studies with the same motive are also carrying out by nuclear industries such as utilities, NPP equipment and system manufacturers and building constructors. This paper consists of three sections, each introducing studies relating to NPP structural seismic design, new siting technology, and upgrading of the methodology of structural design analyses.

    Antonopoulos, Chrissi Argyro

    This study presents findings from survey and interview data investigating replication of green building measures by Commercial Building Partnership (CBP) partners that worked directly with the Pacific Northwest National Laboratory (PNNL). PNNL partnered directly with 12 organizations on new and retrofit construction projects, which represented approximately 28 percent of the entire U.S. Department of Energy (DOE) CBP program. Through a feedback survey mechanism, along with personal interviews, quantitative and qualitative data were gathered relating to replication efforts by each organization. These data were analyzed to provide insight into two primary research areas: 1) CBP partners' replication efforts of green building approaches used in the CBP project to the rest of the organization's building portfolio, and, 2) the market potential for technology diffusion into the total U.S. commercial building stock, as a direct result of the CBP program. The first area of this research focused specifically on replication efforts underway or planned by each CBP program participant. The second area of this research develops a diffusion of innovations model to analyze potential broad market impacts of the CBP program on the commercial building industry in the United States. Findings from this study provided insight into motivations and objectives CBP partners had for program participation. Factors that impact replication include motivation, organizational structure and objectives firms have for implementation of energy efficient technologies. Comparing these factors between different CBP partners revealed patterns in motivation for constructing energy efficient buildings, along with better insight into market trends for green building practices. The optimized approach to the CBP program allows partners to develop green building parameters that fit the specific uses of their building, resulting in greater motivation for replication. In addition, the diffusion model developed

The recommendations are drawn from the Advanced Energy Design Guide for Small to Medium Office Buildings, an ASHRAE publication that provides comprehensive recommendations for designing low-energy-use office buildings with gross floor areas up to 100,000 ft2 (see sidebar). Designed as a stand-alone document, this fact sheet provides key principles and a set of prescriptive design recommendations appropriate for smaller office buildings with insufficient budgets to fully implement best practices for integrated design and optimized performance. The recommendations have undergone a thorough analysis and review process through ASHRAE, and have been deemed the best combination of measures to achieve 50% savings in the greatest number of office buildings.

    Energy simulation models are developed with EnergyPlus for two office buildings in a R and D center in Shanghai, China to evaluate the energy cost savings of green building design options compared with the baseline building. As a R and D center of an international IT corporation, there are data centers in the two buildings, which make them different from typical office buildings. The data centers house high energy consuming IT equipments and need 24 h air-conditioning every day all year round. In order to achieve energy cost savings, multiple energy efficiency strategies are employed for design proposed building, encompassing high performance building envelope, lighting system, and HVAC system. Through energy modeling, the design proposed options are compared to an ASHRAE 90.1-2004 compliant budget model to highlight energy cost savings versus ''standard practice'' and show the potential LEED trademark Credit EA1 - Optimize Energy Performance. Meanwhile, they are also compared to China Code model to figure out the energy cost savings versus the most popular practice conforming to China Public Building Energy Saving Design Standard. The whole building energy simulation results show that the yearly energy cost saving of the proposed design will be approximately 27% from China Code building and 21% from ASHRAE budget building, which can achieve 4 points for LEED credit due to energy performance optimization.

    Full Text Available Energy Efficient Building (EEB design, construction, and operations require the development and sharing of building information among different individuals, organizations, and computer applications. The Representational State Transfer (RESTful Building Information Modeling (BIM web service is a solution to enable an effective exchange of data. This paper presents an investigation into the core RESTful web service requirements needed to effectively support the EEB project lifecycle. The requirements include information exchange requirements, distributed collaboration requirements, internal data storage requirements, and partial model query requirements. We also propose a RESTful web service design model on different abstraction layers to enhance the BIM lifecycle in energy efficient building design. We have implemented a RESTful Application Program Interface (API prototype on a mock BIMserver to demonstrate our idea. We evaluate our design by conducting a user study based on the Technology Acceptance Model (TAM. The results show that our design can enhance the efficiency of data exchange in EEB design scenarios.

    Llatas, C; Osmani, M

    2016-10-01

    Reduction in construction waste is a pressing need in many countries. The design of building elements is considered a pivotal process to achieve waste reduction at source, which enables an informed prediction of their wastage reduction levels. However the lack of quantitative methods linking design strategies to waste reduction hinders designing out waste practice in building projects. Therefore, this paper addresses this knowledge gap through the design and validation of a Building Design Waste Reduction Strategies (Waste ReSt) model that aims to investigate the relationships between design variables and their impact on onsite waste reduction. The Waste ReSt model was validated in a real-world case study involving 20 residential buildings in Spain. The validation process comprises three stages. Firstly, design waste causes were analyzed. Secondly, design strategies were applied leading to several alternative low waste building elements. Finally, their potential source reduction levels were quantified and discussed within the context of the literature. The Waste ReSt model could serve as an instrumental tool to simulate designing out strategies in building projects. The knowledge provided by the model could help project stakeholders to better understand the correlation between the design process and waste sources and subsequently implement design practices for low-waste buildings.

    embedding students in an authentic, contextualized environment where the knowledge domain is an extension, yet integral supplement, to the classroom experience.This presentation describes two different approaches for the use of LEAD in undergraduate education: 1) a use-case for integrating LEAD technology into undergraduate subject material; and 2) making LEAD capability available to a select group of students participating in the National Collegiate Forecasting Contest (NCFC). The use-case (1) is designed to have students explore a particular weather phenomenon (e.g., a frontal boundary, jet streak, or lake effect snow event) through self-guided inquiry, and is intended as a supplement to classroom instruction. Students will use interactive, Web-based, LEAD-to-Learn modules created specifically to build conceptual knowledge of the phenomenon, adjoin germane terminology, explore relationships between concepts and similar phenomena using the LEAD ontology, and guide them through the experiment builder and workflow orchestration process in order to establish a high-resolution WRF run over a region that exhibits the characteristics of the phenomenon they wish to study. The results of the experiment will be stored in the student's MyLEAD workspace from which it can be retrieved, visualized and analyzed for atmospheric signatures characteristic of the phenomenon. The learning process is authentic in that students will be exposed to the same process of investigation, and will have available many of the same tools, as researchers. The modules serve to build content knowledge, guide discovery, and provide assessment while the LEAD portal opens the gateway to real-time observations, model accessibility, and a variety of tools, services, and resources.

  4. Design of energy efficient building with radiant slab cooling

    Science.gov (United States)

    Tian, Zhen

    2007-12-01

    Air-conditioning comprises a substantial fraction of commercial building energy use because of compressor-driven refrigeration and fan-driven air circulation. Core regions of large buildings require year-round cooling due to heat gains from people, lights and equipment. Negative environmental impacts include CO2 emissions from electric generation and leakage of ozone-depleting refrigerants. Some argue that radiant cooling simultaneously improves building efficiency and occupant thermal comfort, and that current thermal comfort models fail to reflect occupant experience with radiant thermal control systems. There is little field evidence to test these claims. The University of Calgary's Information and Communications Technology (ICT) Building, is a pioneering radiant slab cooling installation in North America. Thermal comfort and energy performance were evaluated. Measurements included: (1) heating and cooling energy use, (2) electrical energy use for lighting and equipment, and (3) indoor temperatures. Accuracy of a whole building energy simulation model was evaluated with these data. Simulation was then used to compare the radiant slab design with a conventional (variable air volume) system. The radiant system energy performance was found to be poorer mainly due to: (1) simultaneous cooling by the slab and heating by other systems, (2) omission of low-exergy (e.g., groundwater) cooling possible with the high cooling water temperatures possible with radiant slabs and (3) excessive solar gain and conductive heat loss due to the wall and fenestration design. Occupant thermal comfort was evaluated through questionnaires and concurrent measurement of workstation comfort parameters. Analysis of 116 sets of data from 82 occupants showed that occupant assessment was consistent with estimates based on current thermal comfort models. The main thermal comfort improvements were reductions in (1) local discomfort from draft and (2) vertical air temperature stratification. The

    2016-05-01

    Considerable overlap exists between post-occupancy research evaluating building design quality and the concept of 'social value', popularised by its recent application to issues of the public realm. To outline this potential research agenda, the paper reviews design quality research on buildings in relation to users and their social context where the term 'social context' refers to building user group dynamics, a combination of organisational cultures, management strategies, and social norms and practices. The review is conducted across five key building types, namely housing, workplaces, healthcare, education, and the retail/service sector. Research commonalities and gaps are identified in order to build a more comprehensive picture of the design quality literature and its handling of users in their social context. The key findings concerning each building type are presented visually. It is concluded that the design quality field comprises a patchwork of relatively isolated studies of various building types, with significant potential for theoretical and empirical development through interdisciplinary collaboration. Users tend to be conceived as anonymous and autonomous individuals with little analysis of user identity or interaction. Further, the contextual impact of user group dynamics on the relationship between building design and building user is rarely addressed in the literature. Producing a more nuanced understanding of users in situ is proposed as an important area for future design quality research.

    2007-02-15

    Advanced stack-ventilated buildings have the potential to consume much less energy for space conditioning than typical mechanically ventilated or air-conditioned buildings. This paper describes how environmental design considerations in general, and ventilation considerations in particular, shape the architecture of advanced naturally ventilated (ANV) buildings. The attributes of simple and advanced naturally ventilated buildings are described and a taxonomy of ANV buildings presented. Simple equations for use at the preliminary design stage are presented. These produce target structural cross section areas for the key components of ANV systems. The equations have been developed through practice-based research to design three large educational buildings: the Frederick Lanchester Library, Coventry, UK; the School of Slavonic and East European Studies, London, UK; the Harm A. Weber Library, Elgin, near Chicago, USA. These buildings are briefly described and the sizes of the as-built ANV features compared with the target values for use in preliminary design. The three buildings represent successive evolutionary stages: from advanced natural ventilation, to ANV with passive downdraught cooling, and finally ANV with HVAC support. Hopefully the guidance, simple calculation tools and case study examples will give architects and environmental design consultants confidence to embark on the design of ANV buildings. (author)

    Full Text Available We proposed a support system called the “Smart Partition System” for infill elements that integrate smart technologies according to the Open Building principles. The design requirements were collected from design practitioners. These design requirements consisted of both architectural and information subsystems. The Smart Partition System was composed of the following multiple levels of smartness: the foundation/core level with an embedded design knowledge in the support system and the utility level with a modular infill that integrate smart technologies. We constructed functional prototypes to demonstrate the feasibility of our proposed support system and some of the possibilities of the smart infill elements. Furthermore, the prototypes were evaluated by design practitioners. We compared our approach with current practices of smart building developments, and we also discussed some future prospects.

    Buildings account for almost a third of final energy consumption globally and are an equally important source of CO2 emissions. Currently, both space heating and cooling as well as hot water are estimated to account for roughly half of global energy consumption in buildings. Energy-efficient and low/zero-carbon heating and cooling technologies for buildings have the potential to reduce CO2 emissions by up to 2 gigatonnes (Gt) and save 710 million tonnes oil equivalent (Mtoe) of energy by 2050. Most of these technologies -- which include solar thermal, combined heat and power (CHP), heat pumps and thermal energy storage -- are commercially available today. The Energy-Efficient Buildings: Heating and Cooling Equipment Roadmap sets out a detailed pathway for the evolution and deployment of the key underlying technologies. It finds that urgent action is required if the building stock of the future is to consume less energy and result in lower CO2 emissions. The roadmap concludes with a set of near-term actions that stakeholders will need to take to achieve the roadmap's vision.

    Full Text Available An innovative technology using stone and granite as exterior sheeting of modern steel and concrete tall buildings is presented, Granites are chosen for the indubitable superior durability in any wheather and polluted atmosfere condition. But to guarantee durability stone sheets have to be mounted in such a way as to avoid any inner irregular stress. In particular stresses from deformation of the main structure must not be trasmitted to the exterior sheeting. Moreover an all-proof wheather barrier has to be incorporated in the factory builded sheeting panel. The innovative technology allowing use of granite and stone in facing of tall buildings is here presented along with two very important realisations: The North Tower in Genoa and the Canary Wharf in London.

    The three building envelope functions with the largest impact on the energy usage are illumination, energy flux and energy production. In general, these three functions are addressed separately in the building design. A step change toward a zero-energy building can be achieved with a glazing system that combines these three functions and their control into a single unit. In particular, significant value could be realized if illumination into the building is dynamically controlled such that it occurs during periods of low load on the grid (e.g., morning) to augment illumination supplied by interior lights and then to have that same light diverted to PV energy production and the thermal energy rejected during periods of high load on the grid. The objective of this project is to investigate the feasibility of a glazing unit design that integrates these three key functions (illumination and energy flux control, and power production) into a single module.

    This Technical Support Document (TSD) describes the process and methodology for the development of the Advanced Energy Design Guide for Small Office Buildings (AEDG-SO), a design guidance document intended to provide recommendations for achieving 30% energy savings in small office buildings over levels contained in ANSI/ASHRAE/IESNA Standard 90.1-1999, Energy Standard for Buildings Except Low-Rise Residential Buildings. The AEDG-SO is the first in a series of guides being developed by a partnership of organizations, including the American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc. (ASHRAE), the American Institute of Architects (AIA), the Illuminating Engineering Society of North America (IESNA), the New Buildings Institute (NBI), and the U.S. Department of Energy (DOE). Each of the guides in the AEDG series will provide recommendations and user-friendly design assistance to designers, developers and owners of small commercial buildings that will encourage steady progress towards net-zero energy buildings. The guides will provide prescriptive recommendation packages that are capable of reaching the energy savings target for each climate zone in order to ease the burden of the design and construction of energy-efficient small commercial buildings The AEDG-SO was developed by an ASHRAE Special Project committee (SP-102) made up of representatives of each of the partner organizations in eight months. This TSD describes the charge given to the committee in developing the office guide and outlines the schedule of the development effort. The project committee developed two prototype office buildings (5,000 ft2 frame building and 20,000 ft2 two-story mass building) to represent the class of small office buildings and performed an energy simulation scoping study to determine the preliminary levels of efficiency necessary to meet the energy savings target. The simulation approach used by the project committee is documented in this TSD along with

    Full Text Available Solar technology is becoming increasingly popular. For example, the production of solarcells quadrupled in the 1999-2004 period, with a capacity of four gigawatts worldwide. Renewableenergy including solar power produces few or no harmful emissions and it is becoming increasinglyimportant to exploit it in the future. This paper presents a literature review of the application ofnumerous types of solar technology in buildings in Malaysia and identifies the challenges faced.Although several newly constructed green buildings use solar technology, Malaysia has yet to acceptit wholesale. If solar technology is to be adopted widely, then both public and private sectors mustcooperate to provide large-scale financial incentives and produce specialists in solar technology. Asthe first step, the government has established the Low Energy Office and the Green Energy Office,which use passive solar design and photovoltaic systems in their own buildings. However, the privatesector has yet to follow suit. It is anticipated that the application of solar technology in buildings willencourage sustainable development when all non-renewable energy sources decrease significantly. Ifpeople do not recognise the potential of such technology in daily life, it will soon be too late.

    2010-08-01

    Whole-building simulation and analysis has demonstrated a significant energy savings potential in a wide variety of design projects. Commercial building design, however, traditionally integrates simulation and modeling analyses too late in the design process to make a substantial impact on energy use. The National Renewable Energy Laboratory (NREL) commercial building group created an optimization platform called Opt-E-Plus that uses multivariate and multi-objective optimization theory to navigate a large parameter space and find economically valid, energy-saving solutions. The analysis results provide designers and engineers valuable information that influences the design. The pathways are not full 'construction ready' design alternatives; rather, they offer guidance about performance and cost criteria to reach a range of energy and economic goals. Having this knowledge early in the design phase helps designers establish project goals and direct the design pathway before they make important decisions. Opt-E-Plus has been deployed on several projects, including a retrofit mixed-use building, a new NREL office building, and several nationwide design guides. Each of these projects had different design criteria, goals, and audiences. In each case the analysis results provided pathways that helped inform the design process.

    Full Text Available The purpose of this paper is to investigate if the various risk sources in Design and Build projects can be classified into three risk groups of cost, time and quality using the discriminant analysis technique. Literature search was undertaken to review issues of risk sources, classification of the identified risks into a risk structure, management of risks and effects of risks all on Design and Build projects as well as concepts of discriminant analysis as a statistical technique. This literature review was undertaken through the use of internet, published papers, journal articles and other published reports on risks in Design and Build projects. A research questionnaire was further designed to collect research information. This research study is a survey research that utilized cross-sectional design to capture the primary data. The data for the survey was collected in Nigeria. In all 40 questionnaires were sent to various respondents that included Architects, Engineers, Quantity Surveyors and Builders who had used Design and Build procurement method for their recently completed projects. Responses from these retrieved questionnaires that measured the impact of risks on Design and Build were analyzed using the discriminant analysis technique through the use of SPSS software package to build two discriminant models for classifying risks into cost, time and quality risk groups. Results of the study indicate that time overrun and poor quality are the two factors that discriminate between cost, time and quality related risk groups. These two discriminant functions explain the variation between the risk groups. All the discriminating variables of cost overrun, time overrun and poor quality demonstrate some relationships with the two discriminant functions. The two discriminant models built can classify risks in Design and Build projects into risk groups of cost, time and quality. These classifications models have 72% success rate of classification

Units range in size from 450 ft2 to 1,664 ft2 and cost from $80,000 for a studio apartment to $235,000 for a three- or four-bedroom single-family home. For the research component of this project, CARB analyzed current heating system sizing methods for superinsulated homes in cold climates to determine if changes in building load calculation methodology should be recommended. Actual heating energy use was monitored and compared to results from the Air Conditioning Contractors of America’s Manual J8 (MJ8) and the Passive House Planning Package software. Results from that research indicate that MJ8 significantly oversizes heating systems for superinsulated homes and that thermal inertia and internal gains should be considered for more accurate load calculations.

  7. Technologies for building integrated energy supply; Teknologier for bygningsintegreret energiforsyning

    2011-07-15

    The current report is part of the deliverables from the project ''Building Integrated Energy Supply'' supported by the Danish Energy Authority R and D program. It describes a range of technologies for individual supply of heat and/or electricity to dwellings with respect to their stage of development and possible application in the near future. Energy supply of buildings is becoming more and more complex, partly as a result of increasing demands for comfort, efficiency and reduced emissions, partly as a result of rising oil prices and improved competitiveness of alternative energy sources. The days where ordinary boilers were the dominant source of individual supply of dwellings are becoming past these years. The challenge of the new range of technologies lies to a high extent in the fluctuating nature of their energy conversion and their interaction with the supply grids for heat and electricity. There is thus an increasing demand to understand the nature of the different supply technologies, besides a regular update of their economical key figures. The technologies briefly described in this study are: Solar heating, passive solar energy, biofuel boilers, heat pumps, micro CHP, solar photovoltaic and energy storage systems. The selected technologies are all assessed to play an important role in future's mix of supply technologies in Denmark, especially heat pumps and solar. (Author)

    The energy use in America's commercial and residential building sectors is large and growing. Over 38 quadrillion Btus (Quads) of primary energy were consumed in 2002, representing 39% of total U.S. energy consumption. While the energy use in buildings is expected to grow to 52 Quads by 2025, a large number of energy-related technologies exist that could curtail this increase. In recent years, improvements in such items as high efficiency refrigerators, compact fluorescent lights, high-SEER air conditioners, and improved building shells have all contributed to reducing energy use. Hundreds of other technology improvements have and will continue to improve the energy use in buildings. While many technologies are well understood and are gradually penetrating the market, more advanced technologies will be introduced in the future. The pace and extent of these advances can be improved through state and federal R&D. This report focuses on the long-term potential for energy-efficiency improvement in buildings. Five promising technologies have been selected for description to give an idea of the wide range of possibilities. They address the major areas of energy use in buildings: space conditioning (33% of building use), water heating (9%), and lighting (16%). Besides describing energy-using technologies (solid-state lighting and geothermal heat pumps), the report also discusses energy-saving building shell improvements (smart roofs) and the integration of multiple energy service technologies (CHP packaged systems and triple function heat pumps) to create synergistic savings. Finally, information technologies that can improve the efficiency of building operations are discussed. The report demonstrates that the United States is not running out of technologies to improve energy efficiency and economic and environmental performance, and will not run out in the future. The five technology areas alone can potentially result in total primary energy savings of between 2 and

    2004-08-01

    Machine to Machine (M2M) is a term used to describe the technologies that enable computers, embedded processors, smart sensors, actuators and mobile devices to communicate with one another, take measurements and make decisions--often without human intervention. M2M technology was applied to five commercial buildings in a test. The goal was to reduce electric demand when a remote price signal rose above a predetermine price. In this system, a variable price signal was generated from a single source on the Internet and distributed using the meta-language, XML (Extensible Markup Language). Each of five commercial building sites monitored the common price signal and automatically shed site-specific electric loads when the price increased above predetermined thresholds. Other than price signal scheduling, which was set up in advance by the project researchers, the system was designed to operate without human intervention during the two-week test period. Although the buildings responded to the same price signal, the communication infrastructures used at each building were substantially different. This study provides an overview of the technologies used at each building site, the price generator/server, and each link in between. Network architecture, security, data visualization and site-specific system features are characterized. The results of the test are discussed, including: functionality at each site, measurement and verification techniques, and feedback from energy managers and building operators. Lessons learned from the test and potential implications for widespread rollout are provided.

Great satisfaction verified among the clients and residents and the high ranking performance confirmed for recyclability, reliability, versatility and moisture resistance of EPS building products all herald a great future for the applications of this advanced building products in the Nigerian building industry.

  17. A numerical multivariate approach to optimization of photovoltaic solar low energy building designs

    Energy Technology Data Exchange (ETDEWEB)

    Peippo, K.

    1997-12-31

    The large number of options available to the energy conscious building designer calls for careful assessment of the competitiveness of the various technologies, in order to find the best technology mix for each design. Here, a simplified rigorous numerical multivariate optimization scheme is introduced to address the energy efficient solar low energy building design problem at the early design stages. The approach is based on elementary building modeling and non-linear optimization techniques where the basic physical, technical and economical interactions between the building design options and energy flows are accounted for. The design features considered include building geometry, thermal insulation, windows, daylighting, solar thermal systems and photovoltaics. The applicability of the approach is assessed through a set of case studies for a single-family residential house and a large office building in three different climates in Europe: Helsinki, Finland (60 deg C N), Paris, France (49 deg C N) and Trapani, Italy (38 deg C N). The analysis is based on annual hourly simulations with Test Reference Years. First, the design minimizing the sum of annual capital and energy cost of the building is determined. Then, the optimal path is computed that gives the most economical design to reach a given level of annual primary energy requirements, should this desired level be lower than the one in the least cost option. The optimal values of the key design variables for the case studies are presented. As a typical low energy building design feature, photovoltaics is to be introduced at a relatively early stage in the designs, in order to further decrease the auxiliary energy requirements. This due to the rather high share of electricity in the energy balance of low energy buildings. However, it is crucial for the integrity of low energy building design, that also the other design features are optimized before one resorts to PV. In addition, it is notable that the somewhat

  7. Analyzing Design Heating Loads in Superinsulated Buildings

    Energy Technology Data Exchange (ETDEWEB)

    2015-06-01

    Super-insulated homes offer many benefits including improved comfort, reduced exterior noise penetration, lower energy bills, and the ability to withstand power and fuel outages under much more comfortable conditions than a typical home. While these homes aren't necessarily constructed with excessive mass in the form of concrete floors and walls, the amount of insulation and the increase in the thickness of the building envelope can lead to a mass effect, resulting in the structures ability to store much more heat than a code built home. This results in a very low thermal inertia making the building much less sensitive to drastic temperature swings thereby decreasing the peak heating load demand. During the winter of 2013/2014, CARB monitored the energy use of three homes in climate zone 6 in an attempt to evaluate the accuracy of two different mechanical system sizing methods for low load homes. Based on the results, it is recommended that internal and solar gains be included and some credit for thermal inertia be used in sizing calculations for super insulated homes.

    Building Information Modeling (BIM) may have obvious implications in the process of architectural design and construction at the present stage of technological development. However, BIM has rarely been really assessed and its benefits are often described in generic terms. In this paper we describe an experiment in which some benefits are identified from a comparison between two design processes of the same airport building, one run in an older CAD system and the other in a BIM based approach. The practical advantages of BIM to airport design are considerable.

    Urban reforestation is advocated as an efficient countermeasure to the intensification of urban heat islands. The greening and beautification of residential quarters is one of the main concerns of residents, while lighting and ventilation are two main energy-consuming building services. Hence, the tree layout in green space between buildings is important, and it is necessary to determine the relationships between trees and buildings. This study takes Shanghai as a case study to optimize tree design between residential buildings and meet good daylighting requirements. Models were made using software such as AutoCAD and SketchUp. The relationships between maximum tree height and building separation were determined. For the same building layout, there were different tree height limits according to crown shape; the order of decreasing height limits was cylindrical, conical, spherical, and inverted conical crowns. Three cases having different green space between building layouts were studied. Their maximum tree heights differed. Overall, our model helps us realize good daylighting of a building environment. The formula allows us to determine which trees to plant between buildings in that we can predict the effects of future tree growth on building daylighting. (author)

    Simplified thermal models of buildings can successfully be applied in building design. This paper describes the derivation and validation of a first-order thermal model which has a clear physical interpretation, is based on uncomplicated calculation procedures and requires limited input information. Because extensive simplifications and assumptions are inherent in the development of the model, a comprehensive validation study is reported. The validity of the thermal model was proven with 70 validation studies in 32 buildings comprising a wide range of thermal characteristics. The accuracy of predictions compares well with other sophisticated programs. The proposed model is considered to be eminently suitable for incorporation in an efficient design tool. (orig.)

    In China,a new "Design standard for energy efficiency of residential buildings (for cold region)" was introduced in 2006. In this new standard,more high level insulation of the building envelope is required,yearly energy requirement for heating must be less than 55 kWh/(m2·a)(regarded as a low-energy house). The new attempt was carried out in the process of architecture design with an evaluation on energy consumption of the building. The design plan was brought forward and compared. PHPP software from German was applied to calculate energy consumption of the passive residential building. The optimum design planning was discussed and model of passive house suited to China’s national conditions were attempted. The compactness,solar air collector and the window-wall ratio have essential influence on the energy consumption of buildings. The annual heat demands for the buildings with the window-wall ratio 0.35 and 0.50 are 48 kWh/(m2·a) and 46 kWh/(m2·a),respectively. The yearly auxiliary heat of building with the wall-mounted solar air collectors and the window-wall ratio 0.35 is just 4.8 kWh/(m2·a).

    Essa Jafer

    2011-12-01

    Full Text Available It is commonly agreed that a 15–40% reduction of building energy consumption is achievable by efficiently operated buildings when compared with typical practice. Existing research has identified that the level of information available to Building Managers with existing Building Management Systems and Environmental Monitoring Systems is insufficient to perform the required performance-based building assessment. The majority of today’s buildings are insufficiently sensored to obtain an unambiguous understanding of performance. The cost of installing additional sensors and meters is extremely high, primarily due to the estimated cost of wiring and the needed labour. From these perspectives wireless sensors technology proves to have a greater cost-efficiency while maintaining high levels of functionality and reliability. In this paper, a wireless sensor network mote hardware design and implementation are introduced particularly for building deployment application. The core of the mote design is based on the 8-bit AVR microcontroller, Atmega1281 and 2.4 GHz wireless communication chip, CC2420. The sensors were selected carefully to meet both the building monitoring and design requirements. Beside the sensing capability, actuation and interfacing to external meters/sensors are provided to perform different management control and data recording tasks.

    2011-01-01

    During architectural conception phase,building maintenance problematic is mostly a result of the unintentional use of preconceived architectonical solutions rather than a consequence of a specific influence of maintenance requirements.Hardly the architect in the act of design understands the importance of these solutions in the service life span of a building.Being aware of this,is it possible for the architect to be supplied with a decision support system that allows him to consider the implications of building maintenance since the early design phases? Having awareness of this problem and its consequences in the early design phases a research project was started at the Faculty Engineering of the University of Oporto(FEUP),under which the implications of building maintenance in the act of architectural design is studied.This article presents the methodology developed to identify the needs of maintenance of buildings based on a DSS-decision support system that provides simple tools the architect can use in design phase.This methodology is based on decomposition of building parts-Elements Source of Maintenance ESM-,and subsequently,a set of functional requirements that determine the performance regarding building maintenance on account of architectural decisions.Relevant maintenance actions are defined:Inspection,Pro-action,Cleaning,Correction,Replacement,Legal enforcement,Limits of use.One can thus set up a relationship between the act of design and its performance framework based on behavior,intervention and the ownership of the work of architecture.Using a Multicriteria Analysis (MCA) a qualitative evaluation of different options based on maintenance requirements accomplishment.Conclusions on the importance of architectural conception concerning the building maintenance were clearly arrived at and the utility of the developed decision support tool was also highlighted.

    Given the ability of a Building Information Model (BIM) to serve as a multi-disciplinary data repository, this paper seeks to explore and exploit the sustainability value of Building Information Modelling/models in delivering buildings that require less energy for their operation, emit less CO2 and at the same time provide a comfortable living environment for their occupants. This objective was achieved by a critical and extensive review of the literature covering: (1) building energy consumption, (2) building energy performance and analysis, and (3) building information modeling and energy assessment. The literature cited in this paper showed that linking an energy analysis tool with a BIM model helped project design teams to predict and create optimized energy consumption. To validate this finding, an in-depth analysis was carried out on a completed BIM integrated construction project using the Arboleda Project in the Dominican Republic. The findings showed that the BIM-based energy analysis helped the design team achieve the world's first 103% positive energy building. From the research findings, the paper concludes that linking an energy analysis tool with a BIM model helps to expedite the energy analysis process, provide more detailed and accurate results as well as deliver energy-efficient buildings. The study further recommends that the adoption of a level 2 BIM and the integration of BIM in energy optimization analyse should be made compulsory for all projects irrespective of the method of procurement (government-funded or otherwise) or its size.

    This report is a primer on solar standards development. It explains the development of standards, building code provisions, and certification programs and their relationship to the emerging solar technologies. These areas are important in the commercialization of solar technology because they lead to the attainment of two goals: the development of an industry infrastructure and consumer confidence. Standards activities in the four phases of the commercialization process (applied research, development, introduction, and diffusion) are discussed in relation to institutional issues. Federal policies have been in operation for a number of years to accelerate the development process for solar technology. These policies are discussed in light of the Office of Management and Budget (OMB) Circular on federal interaction with the voluntary consensus system, and in light of current activities of DOE, HUD, and other interested federal agencies. The appendices cover areas of specific interest to different audiences: activities on the state and local level; and standards, building codes, and certification programs for specific technologies. In addition, a contract for the development of a model solar document let by DOE to a model consortium is excerpted in the Appendix.

    Current building energy simulation technology requires excessive labor, time and expertise to create building energy models, excessive computational time for accurate simulations and difficulties with the interpretation of the results. These deficiencies can be ameliorated using modern graphical user interfaces and algorithms which take advantage of modern computer architectures and display capabilities. To prove this hypothesis, we developed an experimental test bed for building energy simulation. This novel test bed environment offers an easy-to-use interactive graphical interface, provides access to innovative simulation modules that run at accelerated computational speeds, and presents new graphics visualization methods to interpret simulation results. Our system offers the promise of dramatic ease of use in comparison with currently available building energy simulation tools. Its modular structure makes it suitable for early stage building design, as a research platform for the investigation of new simulation methods, and as a tool for teaching concepts of sustainable design. Improvements in the accuracy and execution speed of many of the simulation modules are based on the modification of advanced computer graphics rendering algorithms. Significant performance improvements are demonstrated in several computationally expensive energy simulation modules. The incorporation of these modern graphical techniques should advance the state of the art in the domain of whole building energy analysis and building performance simulation, particularly at the conceptual design stage when decisions have the greatest impact. More importantly, these better simulation tools will enable the transition from prescriptive to performative energy codes, resulting in better, more efficient designs for our future built environment.

    Full Text Available Recent global developments in awareness and concerns about environmental problems have led to reconsidering built environment approaches and construction techniques. One of the alternatives is the principle of low/zero-energy buildings. This study investigates the potentials of energy savings in an existing multi-story building in the Mediterranean region in order to achieve net-zero energy as a solution to increasing fossil fuel prices. The Colored building at the Faculty of Architecture, Eastern Mediterranean University, Cyprus was chosen as a target of this study to be investigated and analyzed in order to know how energy efficiency strategies could be applied to the building to reduce annual energy consumption. Since this research objective is to develop a strategy to achieve net-zero energy in existing buildings, case study and problem solving methodologies were applied in this research in order to evaluate the building design in a qualitative manner through observations, in addition to a quantitative method through an energy modeling simulation to achieve desirable results which address the problems. After optimizing the building energy performance, an alternative energy simulation was made of the building in order to make an energy comparison analysis, which leads to reliable conclusions. These methodologies and the strategies used in this research can be applied to similar buildings in order to achieve net-zero energy goals.

    Double wall technologies utilizing wood framing have been well-known and used in North American buildings for decades. Most of double wall designs use only natural materials such as wood products, gypsum, and cellulose fiber insulation, being one of few building envelope technologies achieving high thermal performance without use of plastic foams or fiberglass. Today, after several material and structural design modifications, these technologies are considered as highly thermally efficient, sustainable option for new constructions and sometimes, for retrofit projects. Following earlier analysis performed for U.S. Department of Energy by Fraunhofer CSE, this paper discusses different ways to build double walls and to optimize their thermal performance to minimize the space conditioning energy consumption. Description of structural configuration alternatives and thermal performance analysis are presented as well. Laboratory tests to evaluate thermal properties of used insulation and whole wall system thermal performance are also discussed in this paper. Finally, the thermal loads generated in field conditions by double walls are discussed utilizing results from a joined project performed by Zero Energy Building Research Alliance and Oak Ridge National Laboratory (ORNL), which made possible evaluation of the market viability of low-energy homes built in the Tennessee Valley. Experimental data recorded in two of the test houses built during this field study is presented in this work.

    Glezil, Dorothy

    NEHRP's Provisions today currently governing conventional seismic resistant design. These provisions, though they ensure the life-safety of building occupants, extensive damage and economic losses may still occur in the structures. This minimum performance can be enhanced using the Performance-Based Earthquake Engineering methodology and passive control systems like base isolation and energy dissipation systems. Even though these technologies and the PBEE methodology are effective reducing economic losses and fatalities during earthquakes, getting them implemented into seismic resistant design has been challenging. One of the many barriers to their implementation has been their upfront costs. The green building community has faced some of the same challenges that the high performance seismic design community currently faces. The goal of this thesis is to draw on the success of the green building industry to provide recommendations that may be used overcome the barriers that high performance seismic design (HPSD) is currently facing.

    Simulation of the heat flow into the ground underneath a building is usually performed by means of procedures which do not take into account other heat flow paths. An efficient design tool for buildings in ground contact is lacking. This paper consequently describes how heat flow into the ground can be simplified and incorporated in an efficient design tool. The design tool is based on a first order thermal model calculated by means of straightforward equations. Other features of the design tool include the simulation of multizone behaviour, comfort temperatures, time dependent thermal parameters such as variable ventilation as well as alternative air-conditioning systems such as evaporative and structural cooling. The proposed simulation of ground contact is validated in 53 existing buildings comprising a wide range of thermal characteristics. (Author)

    Lee, Keun

    Renewable energy in different forms has been used in various applications for survival since the beginning of human existence. However, there is a new dire need to reevaluate and recalibrate the overall energy issue both nationally and globally. This includes, but is not limited to, the finite availability of fossil fuel, energy sustainability with an increasing demand, escalating energy costs, environmental impact such as global warming and green-house gases, to name a few. This dissertation is primarily focused and related to the production and usage of electricity from non-hydro renewable sources. Among non-hydro renewable energy sources, electricity generation from wind and solar energy are the fastest-growing technologies in the United States and in the world. However, due to the intermittent nature of such renewable sources, energy storage devices are required to maintain proper operation of the grid system and in order to increase reliability. A hybrid system, as the name suggests, is a combination of different forms of non-renewable and renewable energy generation, with or without storage devices. Hybrid systems, when applied properly, are able to improve reliability and enhance stability, reduce emissions and noise pollution, provide continuous power, increase operation life, reduce cost, and efficiently use all available energy. In the United States (U.S.), buildings consume approximately 40% of the total primary energy and 74% of the total electricity. Therefore, reduction of energy consumption and improved energy efficiency in U.S. buildings will play a vital role in the overall energy picture. Electrical energy usage for any such building varies widely depending on age (construction technique), electricity and natural gas usage, appearance, location and climate. In this research, a hybrid system including non-renewable and renewable energy generation with storage devices specifically for building applications, is studied in detail. This research deals

    This study provides insight into the development of hydrogen and fuel cell technologies in the Netherlands (1980-2007). This is done by applying a Technological Innovation System (TIS) approach. This approach takes the perspective that a technology is shaped by a surrounding network of actors, institutions and technologies. When a technology is in an early stage of development, a TIS has yet to be built up in order to propel technological progress. This build-up process is studied for the hydrogen and fuel cell innovation system in the Netherlands. This is done by systematically studying the dynamics of seven key activities that accelerated (or slowed down) developments around hydrogen and fuel cell technologies. The analysis contributes to a better understanding of these dynamics and of the drivers and barriers that caused them to emerge. The study derives important lessons for practitioners. (author)

    Mwafy, Aman

    2011-03-01

    To verify the seismic design response factors of high-rise buildings, five reference structures, varying in height from 20- to 60-stories, were selected and designed according to modern design codes to represent a wide range of concrete wall structures. Verified fiber-based analytical models for inelastic simulation were developed, considering the geometric nonlinearity and material inelasticity of the structural members. The ground motion uncertainty was accounted for by employing 20 earthquake records representing two seismic scenarios, consistent with the latest understanding of the tectonic setting and seismicity of the selected reference region (UAE). A large number of Inelastic Pushover Analyses (IPAs) and Incremental Dynamic Collapse Analyses (IDCAs) were deployed for the reference structures to estimate the seismic design response factors. It is concluded that the factors adopted by the design code are adequately conservative. The results of this systematic assessment of seismic design response factors apply to a wide variety of contemporary concrete wall buildings with various characteristics.

    Full Text Available The essence of building design process and management for building sustainability in the creation and maintenance of a qualitative architectural product is investigated in this paper. The design process, concept of building sustainability and particularly the quality of the built environment are discussed. Akure, a state capital in Nigeria was used as a case study. The principles and indicators for sustainability of buildings and its implications on the quality of the environment are examined in details. Survey findings include the views of the professionals on the clients, perception on the design process as well as management of projects, and the implications on the quality of the ensuring products and the city’s environment. The data were factor analyzed using varimax rotation criterion (with Kaiser Normalization. The results revealed that five factors were effective, with one of them exhibiting the greatest variability and individual differences. The variables that loaded on this factor were really the aspects of the process and management relating to the clients. The findings also revealed the professionals’ wrong attitude towards design process as shown with a very high degree of variability in the study. The paper concludes by recommending the enactment and enforcement of relevant policies with adequate education of the people and the involvement of all the stakeholders in the management of building projects and environmental programmes for the realization of a qualitative architectural product.

    Occupying new, active design office buildings designed for health promotion and connectivity provides an opportunity to evaluate indoor environment effects on healthy behaviour, sedentariness and workplace perceptions. To determine if moving to a health-promoting building changed workplace physical activity, sedentary behaviour, workplace perceptions and productivity. Participants from four locations at the University of Sydney, Australia, relocated into a new active design building. After consent, participants completed an online questionnaire 2 months before moving and 2 months after. Questions related to health behaviours (physical activity and sitting time), musculoskeletal issues, perceptions of the office environment, productivity and engagement. There were 34 participants (60% aged 25-45, 78% female, 84% employed full-time); 21 participants provided complete data. Results showed that after the move participants spent less work time sitting (83-70%; P workplace were in an open-plan office, compared to 16% before moving. Participants perceived the new work environment as more stimulating, better lit and ventilated, but noisier and providing less storage. No difference was reported in daily physical activity, number of stairs climbed or productivity. Moving to an active design building appeared to have physical health-promoting effects on workers, but workers' perceptions about the new work environment varied. These results will inform future studies in other new buildings. © The Author 2016. Published by Oxford University Press on behalf of the Society of Occupational Medicine. All rights reserved.

    1993-01-01

    The software engineering and quality assurance disciplines are a requisite to the design of safe and effective software-based medical devices. It is in the areas of software methodology and process that the most beneficial application of these disciplines to software development can be made. Software is a product of complex operations and methodologies and is not amenable to the traditional electromechanical quality assurance processes. Software quality must be built in by the developers, with the software verification and validation engineers acting as the independent instruments for ensuring compliance with performance objectives and with development and maintenance standards. The implementation of a software quality assurance program is a complex process involving management support, organizational changes, and new skill sets, but the benefits are profound. Its rewards provide safe, reliable, cost-effective, maintainable, and manageable software, which may significantly speed the regulatory review process and therefore potentially shorten the overall time to market. The use of a trial project can greatly facilitate the learning process associated with the first-time application of a software quality assurance program.

  1. Plausibility in Early Stages of Architectural Design: A New Tool for High-Rise Residential Buildings

    Dirk Donath; Danny Lobos

    2009-01-01

    This paper analyzes the problem of the design of envelopes for high-rise isolated residential build-ings. The phenomenon of envelope creation appears in the early stages of the architectural design. Vari-ables that influence the final shape and size of such envelopes are then identified. This paper presents the state-of-the-art tools for the current solutions at the commercial and academic/scientific level. The variables identified in this research are the client's needs, the urban code and architectural practice, and their specific components for the final creation of a new decision support system tool based on the building information modeling (BIM) software platform, to facilitate the work in the project development and drawing production stages. This tool generates several options for building envelopes according to the parameters required by the city Zoning Planning Commission. These options then lead to deliver reliable data and a geometry that can be analyzed in a timely fashion by the engineers, builders, architects, government, and clients in the early stages of the building's design. The results show that use of specific information and communication technologies (ICT) tools in the early stages of a building design helps reduce the working time, increases confidence in the generated solution, and contributes to the exploration of altematives in a short period of time.

  2. Bridging the gap between building science and design studios

    Energy Technology Data Exchange (ETDEWEB)

    Papamichael, Konstantinos; Pal, Vineeta

    2002-02-06

    Design studios and building science courses have been conducted independent of each other, mainly due to a lack of tools that allow quick and easy consideration of building science criteria, such as comfort and energy requirements, during the design process. Existing tools are not user-friendly and their use requires significant effort in gaining familiarity with the input requirements, understanding the modeling assumptions and interpreting the output. This paper is about the Building Design Advisor (BDA), an evolving computer-based tool intended to bridge the gap between design studios and building science considerations by addressing the above-mentioned limitations of existing tools. BDA allows automatic preparation of input files to multiple simulation tools while the user is working in a CAD environment. BDA automatically activates the relevant simulation tools when the user selects performance parameters to be computed and provides the results in a graphical form, allowing comparison of multiple design options with respect to multiple performance criteria. The paper includes considerations for the use of the BDA in the design studio and ends with a description of the current development efforts and future plans.

    Luciana Alves Oliveira

    2012-06-01

    Full Text Available In many countries, the design begins by the performance definition of the building parts. The data are then used as a reference to select the viable construction technologies. In Brazil, this practice is still uncommon, mostly in residential projects, because, first, it is defined the architectural characteristics, technological solutions and cost for after consider the technical performance requirements. However, this scenario tends to change due to the publication of the Brazilian performance standard ABNT NBR 15575 (2008 that establishes requirements and quantitative parameters to the five main residential building subsystems (structure, floors, wall partition, envelope and covering, and hydraulic installations, besides to the general requirements for all building. The current version contains requirements for structural performance, fire safety, watertightness, thermal and acoustic performances, functionality, accessibility, environmental impact, durability and maintenance. This standard also considers the concepts of Service Life, Design Life and guaranties periods. The aim of this paper is to present some considerations which must be included to the design process of wall partition for the accomplishment of the performance requirements of ABNT NBR 15575-4 (2008. The considerations are designed to wall partitions, but they can be used as an example to the others building subsystems. This paper was developed based on the bibliographical research and on four case studies, which illustrate how the design process of the wall partition needs to change and what needs to be worked on in order to attend the performance concept and requirements of NBR 15575 (2008.

  8. An Examination of the Performance Based Building Code on the Design of a Commercial Building

    Directory of Open Access Journals (Sweden)

    2012-11-01

    Full Text Available The Building Code of Australia (BCA is the principal code under which building approvals in Australia are assessed. The BCA adopted performance-based solutions for building approvals in 1996. Performance-based codes are based upon a set of explicit objectives, stated in terms of a hierarchy of requirements beginning with key general objectives. With this in mind, the research presented in this paper aims to analyse the impact of the introduction of the performance-based code within Western Australia to gauge the effect and usefulness of alternative design solutions in commercial construction using a case study project. The research revealed that there are several advantages to the use of alternative designs and that all parties, in general, are in favour of the performance-based building code of Australia. It is suggested that change in the assessment process to streamline the alternative design path is needed for the greater use of the performance-based alternative. With appropriate quality control measures, minor variations to the deemed-to-satisfy provisions could easily be managed by the current and future building surveying profession.

  9. Effect of wind in the design of reinforced concrete buildings

    Directory of Open Access Journals (Sweden)

    L.S. Tapajós

    Full Text Available ABSTRACT This paper presents the results from a parametric study carried in order to quantify how far errors in the design stage related to the consideration of the wind action may put at risk the response and safety of reinforced concrete buildings. Using an architectural model as reference and varying the number of floors of the building, the structural safety was evaluated as a function of the wind action intensity. Results showed that even for low-rise buildings, with 10 floors, ignoring the wind action can significantly jeopardize their behaviour and safety. Yet, for slenderer buildings, up to 30 floors, it can lead to catastrophic results, as the ruin of the structure by progressive collapse.

    1992-04-30

    In an effort to encourage the maximum cost-effective level of energy efficiency in new building design, energy-efficiency standards have become more location-specific and performance-based. As a result, standards often provide more than one path for ensuring and demonstrating that a design complies, but at the cost of increased complexity. In addition, the burden of remedying a noncompliant design rests on the designers' knowledge and experience, with only general guidance provided by the standards. As part of efforts in the US Department of Energy's (DOE's) Advanced Energy Design and Operation Technologies (AEDOT) project, a team at DOE's Pacific Northwest Laboratory is developing a computer program known as the Energy Standards Intelligent Design Tool (ES-IDT). The ES-IDT is one component of a prototype computer-based building design environment. It performs automatic compliance checking for parts of ASHRAE/IES Standard 90.1-1989 and provides designers assistance in bringing noncomplying designs into compliance. This paper describes the ES-IDT, the functions it provides, and how it is integrated into the design process via the AEDOT prototype building design environment. 9 refs.

    2003-01-01

    Full Text Available Noise source for buildings adjacent to streets is traffic-generated predominantly. Where people are mostly spend their time indoors, it is important for buildings to have screening or blocking to control noise intrusion into living spaces. But this blocking should also permit airflow. This is important for middle to low-cost domestic buildings, which do not employ conditioned ventilation. A common feature of Indonesian buildings, fence, is studied to perform noise barrier. The fence -a barrier to be- should obey three factors: position, dimension, and material. All these three factors were studied to seek compromised design for acoustic performance and natural ventilation purpose. Domestic building situated in the urban area of Yogyakarta was studying to see the most possible design of the barrier to be. There are two calculation methods employed to investigate the proposed design. The study shows that it is possible to gain minimum of 10 dB noise reduction by placing windows within the shadow effect of approximately 1.5 height fence-barrier.

    2013-10-01

    Full Text Available The most progress in the area of the sustainable building policy and its implementation has been achieved in certain regions by the Building Certification System regulations such as Passivhaus (Germany and LEED (U.S. These solutions are similar to the more widely discussed and already applied concepts: the Integrated Whole Building Design (IWBD and Building Information Modeling (BIM. Although it may sound trivial, it is vital to acknowledge and understand that a building is an integral component of the land lot. In the stage of development of a building concept, it usually lacks a versatile and professional assessment of available resources, especially those of renewable energy. It is suggested at the beginning of the IWBD concept to conduct such assessment on the resources available and more specifically focusing on renewable energy. The assessment should also meet the expectations of the building’s owner to use effectively the potential of all possible solutions. Thus a certificate is drawn up, defining all the resources available for the particular lot. The structure of the certificate data is orientated towards the possibility of designing modern renewable energy technologies, according to their performance under changing weather conditions during the year. Such assessment certificates contribute to shaping the concept of the building and allow achieving the highest level of its sustainability.Article in Lithuanian

    Full Text Available In Malaysian construction industry, problem is a common occurrence that hinders the project to run smoothly, notably in traditional contracting system where the design and construction process are separated. Previous research revealed that buildability is able to minimise these problems as it link the design and construction. This study outlines the buildability in design stage. Extensive reviews have been carried out on previous researches on buildability concepts, attributes, principles and other areas related to, and contributing to buildability mainly in the design phase. The term ‘buildability attribute’ has been selected in this study to describe those characteristics which directly or indirectly optimize integration of construction knowledge in the building process and balancing the various project and environment constraints to maximize project goals and building performance. Close examinations of available references revealed that altogether there are 19 buildability attributes that can be implemented during the design phase. The results of survey show that Malaysian construction industry practitioners rate the attribute Provide Clear and Complete Design Information (4.56 as the most important and Less Work Below Ground (3.60 as the least important attribute. The client, consultant and contractor share the same opinion regarding the most important and least important attributes, only higher instituiton’s view is slightly different. Out of 19 attributes, 11 attributes have mean values above 4.00, which indicate them as important attributes. This study has successfully measure the importance level of design buildability attributes for building construction in Malaysia.

    Full Text Available The paper presents results of investigations on rational usage of mineral resources. In particular, it has shown the possibility to increase a period of raw material serviceability and its application for production of building products depending on chemical and mineralogical composition of the waste. Analysis of the executed investigations shows that import substitution of anthracite, lignite and black coal for local fuels (milled peat and its sub-standard product is possible in the production technology of porous building materials.A mathematical model for drying process has been developed in the paper. Technology for thermal performance of a sintering machine with calculation of its length at the given pallet speed has been proposed on the basis of the developed model. Once-through circulation of flue gases and heated materials is the main specific feature of belt sintering machines being used in production. In such a case the whole drying process can be divided into two periods: a period of constant drying rate and a period of falling drying rate. Calculations have shown that the drying rate depends on moisture content but it does not depend on heat exchange Bio-criteria, however, heating rate is a function of temperature and Biq. A mechanism of moisture transfer using various drying methods is the same as in an environment with constant temperature and so in an environment with variable temperature. Application of the mathematical model provides the possibility to save significantly power resources expended for drying process.The paper gives description of methodology for calculation of technologically important optimum parameters for sintering processes of agglomeration while using milled peat.

    Full Text Available This study sought to optimize the envelope thermal design of free-running urban residential buildings in Malawi. It specifically set out to improve the urban residential buildings’ thermal comfort and suggest optimal envelope thermal design features for these buildings. The research study was primarily dependent on computer simulations in EnergyPlus to replicate the typical Malawian urban residential building’s thermal behaviour and then study the impacts of various envelope configurations on the thermal comfort conditions registered in the building. The simulation model was experimentally validated to check its appropriateness to the climatic design conditions prevalent in Malawi and out of the three major cities that were considered, the model was found to be appropriate for use in the two cities of Mzuzu and Lilongwe leaving out the city of Blantyre. The optimization methodology that was employed involved the use of orthogonal arrays, statistical analyses and the listing method. It was found that the optimal envelope thermal design, which registered up to 18% lower discomfort hours than that of the typical urban residential building, consists of a 50 mm concrete floor slab, 230 mm burnt brick walls with an external layer of 19 mm EPS, tiled roof with an internal layer of sarking and 50 mm EPS, double Low-E Glazing with a transparency ratio of 45% and 0.2408 m2 of adaptable operational surface area for the air bricks. Out of all the envelope features that were studied, air infiltration registered the most significant contribution towards the ultimate residential building thermal performance. It was demonstrated that controlled air infiltration through the use of operable air bricks whose operational surface area is adaptable can be very effective in enhancing the building’s comfort levels. It was further observed that excessive insulation of the building envelope generally has a detrimental effect on the indoor space thermal comfort

    Full Text Available The primary objectives of this study are to investigate effects of varying design parameters on the tube action and shear lag behavior of a typical reinforced concrete bundled tube building, and propose optimal design approaches for similar structures. A parametric study was conducted with selected key design variables on the performance of a 41 story building. The design variables considered for the parametric study include the column depth, beam depth, column width and beam width of the moment frames. The performance of each model was assessed in terms of overall and critical (maximum story drifts, and shear lag behavior. Overall, the effects of the column depth on the tube action and shear lag behavior were more prominent than the other member dimensions.

  5. Invention, design and performance of coconut agrowaste fiberboards for ecologically efficacious buildings

    Science.gov (United States)

    Lokko, Mae-ling Jovenes

    As global quantities of waste by-products from food production as well as the range of their applications increase, researchers are realizing critical opportunities to transform the burden of underutilized wastes into ecological profits. Within the tropical hot-humid region, where half the world's current and projected future population growth is concentrated, there is a dire demand for building materials to meet ambitious development schemes and rising housing deficits. However, the building sector has largely overlooked the potential of local agricultural wastes to serve as alternatives to energy-intensive, imported building technologies. Industrial ecologists have recently investigated the use of agrowaste biocomposites to replace conventional wood products that use harmful urea-formaldehyde, phenolic and isocyanate resins. Furthermore, developments in the performance of building material systems with respect to cost, energy, air quality management and construction innovation have evolved metrics about what constitutes material 'upcycling' within building life cycle. While these developments have largely been focused on technical and cost performance, much less attention has been paid to addressing deeply-seated social and cultural barriers to adoption that have sedimented over decades of importation. This dissertation evaluates the development coconut agricultural building material systems in four phases: (i) non-toxic, low-energy production of medium-high density boards (500-1200 kg/m3) from coconut fibers and emerging biobinders; (ii) characterization and evaluation of coconut agricultural building materials hygrothermal performance (iii) scaled-up design development of coconut modular building material systems and (iv) development of a value translation framework for the bottom-up distribution of value to stakeholders within the upcycling framework. This integrated design methodological approach is significant to develop ecological thinking around agrowaste

    2016-07-01

    This research shows the energy analysis of the Electrical Engineering Building, located on campus of the Industrial University of Santander in Bucaramanga - Colombia. This building is a green pilot for analysing energy saving strategies such as solar pipes, green roof, daylighting, and automation, among others. Energy analysis was performed by means of DesignBuilder software from virtual model of the building. Several variables were analysed such as air temperature, relative humidity, air velocity, daylighting, and energy consumption. According to two criteria, thermal load and energy consumption, critical areas were defined. The calibration and validation process of the virtual model was done obtaining error below 5% in comparison with measured values. The simulations show that the average indoor temperature in the critical areas of the building was 27°C, whilst relative humidity reached values near to 70% per year. The most critical discomfort conditions were found in the area of the greatest concentration of people, which has an average annual temperature of 30°C. Solar pipes can increase 33% daylight levels into the areas located on the upper floors of the building. In the case of the green roofs, the simulated results show that these reduces of nearly 31% of the internal heat gains through the roof, as well as a decrease in energy consumption related to air conditioning of 5% for some areas on the fourth and fifth floor. The estimated energy consumption of the building was 69 283 kWh per year.

    2008-01-01

    The objective of this ongoing joint research program is to determine how 3D/4D modeling, simula- tion and visualization of Products (buildings), Organizations and Processes (POP) can support lean con- struction. Initial findings suggest that Process Design Pattern may have the potential to intuitively support ICT based lean construction. We initiated a "Process Archeology" in order to reveal the requirements for tools that can support the planning, simulation and control of lean construction methods. First findings show that existing tools provide only limited support and therefore, we started to develop new methodologies and technologies to overcome these shortcomings. Through the introduction of Process Design Patterns, we in- tent to establish process thinking in the interdisciplinary POP design. Optimized construction processes may be synthesized with semi-automatic methods by applying Process Design Pattems on building structures. By providing process templates that integrate problem solution and expert knowledge, Process Design Pat- tems may have the potential to ensure high quality process models.

    Levine, M.D.; Busch, J.F. [eds.

    1992-06-01

    This volume reports on research in the area of energy conservation technology applied to commercial buildings in the Association of Southeast Asian Nations (ASEAN) region. Unlike Volume I of this series, this volume is a compilation of original technical papers prepared by different authors in the project. In this regard, this volume is much like a technical journal. The papers that follow report on research conducted by both US and ASEAN researchers. The authors representing Indonesia, Malaysia, Philippines, and Thailand, come from a range of positions in the energy arena, including government energy agencies, electric utilities, and universities. As such, they account for a wide range of perspectives on energy problems and the role that technology can play in solving them. This volume is about using energy more intelligently. In some cases, the effort is towards the use of more advanced technologies, such as low-emittance coatings on window glass, thermal energy storage, or cogeneration. In others, the emphasis is towards reclaiming traditional techniques for rendering energy services, but in new contexts such as lighting office buildings with natural light, or cooling buildings of all types with natural ventilation. Used in its broadest sense, the term ``technology`` encompasses all of the topics addressed in this volume. Along with the more customary associations of technology, such as advanced materials and equipment and the analysis of their performance, this volume treats design concepts and techniques, analysis of ``secondary`` impacts from applying technologies (i.e., unintended impacts, or impacts on parties not directly involved in the purchase and use of the technology), and the collection of primary data used for conducting technical analyses.

    2003-01-01

    Components so far have been mainly used in commercial software development to reduce time to market. While some effort has been spent on formal aspects of components, most of this was done in the context of programming language or operating system framework integration. As a consequence, increased reliability of composed systems is mainly regarded as a side effect of a more rigid testing of pre-fabricated components. In contrast to this, Design for Verification (D4V) puts the focus on component specific property guarantees, which are used to design systems with high reliability requirements. D4V components are domain specific design pattern instances with well-defined property guarantees and usage rules, which are suitable for automatic verification. The guaranteed properties are explicitly used to select components according to key system requirements. The D4V hypothesis is that the same general architecture and design principles leading to good modularity, extensibility and complexity/functionality ratio can be adapted to overcome some of the limitations of conventional reliability assurance measures, such as too large a state space or too many execution paths.

    Energy-efficient design for buildings (EEDB) is a vital step towards building energy-saving. In or-der to greatly improve the EEDB, the next generation EEDB software that makes use of latest technologies needs to be developed. This paper mainly focuses on establishing the model of the next generation EEDB software. Based on the investigation of literatures and the interviews to the designers, the requirements on the next generation EEDB software were identified, where the lifecycle assessment on both energy con-sumption and environmental impacts, 3D graphics support, and building information modeling (BIM) support were stressed. Then the workflow for using the next generation EEDB software was established. Finally,based on the workflow, the framework model for the software was proposed, and the partial models and the corresponding functions were systematically analyzed. The model lays a solid foundation for developing the next generation EEDB software.

    Full Text Available Original screw designs of buildings and columns are offered. Frameworks of these buildings and columns are the bearing elements and means of external and internal decoration of buildings and constructions. Originality of such buildings and columns frameworks is ensured by the fact that their design is decorated on the outer surface with broken or smooth screw edges and screw surfaces. Versatility of the offered screw columns trunks designs, as well as the possibility of performance of their left or right screwing allows reaching certain symmetry or their repeatability in the form of harmonious alternation of the bearing trunks of screw columns and spaces between them. Giving to numerous sides of trunks of screw columns of a certain invoice, or their coloring in different colors, will contribute even more to their expressiveness and beauty. Durability and vibration resistance (including seismic of such trunks of screw columns at the same volumes of construction materials, in comparison with round and rectangular trunks is higher

    In many cases natural ventilation may be sufficient to ensure acceptable comfort levels in occupied buildings. In these cases, installation of energy-intensive active environmental control systems will not be necessary. This will result in considerable energy and cost savings and also indirectly in a reduced burden on the environment, since the use of energy is always associated with the production of waste materials. This paper decribes the development of a new model to predict natural ventilation flow rates in buildings. The model is based on the concept of a flow network where openings are represented by non-linear flow resistances. It takes into account the effect of both wind-induced pressures and pressures due to thermal forces. The model draws on a healthy balance between purely theoretical equations and empirical data. The new flow model was linked to an existing thermal model to produce a new integrated design tool for naturally ventilated buildings. It takes into account the important interaction between the flow model and the thermal model and can therefore be used to predict the natural ventilation flow rates as well as the resulting indoor air temperatures. The applicability of the new tool is illustrated through a case study. From this it is clear that the tool can be used successfully to optimize passive building design. The optimized design illustrated here not only resulted in minimum initial cost, but also in improved passive thermal comfort in summertime and a reduction in winter heating energy consumption.

    2009-07-01

    Windows have a high influence on the energy performance and indoor thermal environment of residential buildings. Standard energy calculation programs do not permit an easy comparison of different window designs in a house. A user-friendly calculation program based on simple input data was developed with the purpose of assisting engineers and architects during the process of designing windows in residential buildings. The program is suitable for the early design phase of new residential buildings or when renovating existing ones. Different types of analyses may be performed: net energy gain of individual windows, energy consumption of windows when used in a specific house on a seasonal basis, indoor thermal environment of critical rooms on an hourly basis and also a simple economic evaluation. The thermal calculation method is according to the European standard EN ISO 13790. An example of use of the calculation program for redesigning an existing type house to a higher energy performance based on use of improved windows and an optimized use of windows in the building is presented.

    This paper describes the challenges involved in the construction of a mid-rise housing development in Boston, Massachusetts, during which the development team elected to upgrade the initial design criteria from Minimum Building Code to Energy Star and Leadership in Energy and Environmental Design (LEED) certification. The various constraints imposed on the development were discussed, including constraints imposed by the involvement of substantial public funds as well as the constraints imposed by various funding sources that were approached to leverage energy efficiency and green building investment via competitive grant solicitations. Building owner and utility cost management priorities were outlined along with details of central mechanical system selection. Issues concerning isolation and compartmentalization were examined along with indoor pollution source control. A building load analysis was presented as well as details of daily heating and cooling statistics. Electric generation system integration issues were also presented. It was concluded that the constraints of the project and conditions of targeted assistance ultimately impeded full integration of the design. As a result, some measures appeared to work at cross-purposes with other objectives. Despite many challenges, the development team made significant progress towards optimization within the realistic constraints of the subsidized housing industry. 4 refs., 4 tabs., 4 figs.

  1. On ethics and the earthquake resistant interior design of buildings.

    Science.gov (United States)

    Hurol, Yonca

    2014-03-01

    The most common tectonic quality of modern structures, such as frame systems, is their flexibility; they are open for change. Although this characteristic is a big advantage in comparison to the inflexible masonry structures of the past, it might also create some serious problems, such as e.g. the lack of safety in the event of an earthquake, if the flexibility is not used consciously by architects and interior designers. This article attempts to define and establish some rules for the interior design of buildings with reinforced concrete frame systems. The rules for making subtractions from these structures and extending them by making additions to them are contained within this article. The main objective of this article is to derive some ethical values from these rules. Thus, the conclusion of the article focuses on the derivation of some ethical values for achieving earthquake resistant interior design of buildings with reinforced concrete frame systems.

    2012-01-01

    Designing technology to address the problem of heterogeneous embedded systems, while remaining compatible with standard “More Moore” flows, i.e. capable of handling simultaneously both silicon complexity and system complexity, represents one of the most important challenges facing the semiconductor industry today. While the micro-electronics industry has built its own specific design methods to focus mainly on the management of complexity through the establishment of abstraction levels, the emergence of device heterogeneity requires new approaches enabling the satisfactory design of physically heterogeneous embedded systems for the widespread deployment of such systems. This book, compiled largely from a set of contributions from participants of past editions of the Winter School on Heterogeneous Embedded Systems Design Technology (FETCH), proposes a broad and holistic overview of design techniques used to tackle the various facets of heterogeneity in terms of technology and opportunities at the physical ...

Initial studies explored the interactions of the dodecanethiol passivated gold nanocluster, held in solution with toluene, and the native oxide covered silicon surface. Deposition of the clusters is achieved by pippetting mu-litre quantities of the solution onto the surface, and allowing the solvent to evaporate leaving the clusters as residue. Patterning of the surface with micron scale photoresist structures prior to cluster exposure, led to the selective aggregation of cluster deposits along the resist boundaries. An extension of this technique, examined the flow of the cluster solution along photoresist structures which extended beyond the solution droplet. Investigation into the electronic properties of nanocluster arrays generated non-linear current-voltage curves, which are explained in terms of two very simple models. These results cast doubt over the suitab...

    2004-01-30

    A key finding of this research program was that Laccase Mediator Systems (LMS) treatments on high-kappa kraft could be successfully accomplished providing substantial delignification (i.e., > 50%) without detrimental impact on viscosity and significantly improved yield properties. The efficiency of the LMS was evident since most of the lignin from the pulp was removed in less than one hour at 45 degrees C. Of the mediators investigated, violuric acid was the most effective vis-a-vis delignification. A comparative study between oxygen delignification and violuric acid revealed that under relatively mild conditions, a single or a double LMS{sub VA} treatment is comparable to a single or a double O stage. Of great notability was the retention of end viscosity of LMS{sub VA} treated pulps with respect to the end viscosity of oxygen treated pulps. These pulps could then be bleached to full brightness values employing conventional ECF bleaching technologies and the final pulp physical properties were equal and/or better than those bleached in a conventional ECF manner employing an aggressively O or OO stage initially. Spectral analyses of residual lignins isolated after LMS treated high-kappa kraft pulps revealed that similar to HBT, VA and NHA preferentially attack phenolic lignin moieties. In addition, a substantial decrease in aliphatic hydroxyl groups was also noted, suggesting side chain oxidation. In all cases, an increase in carboxylic acid was observed. Of notable importance was the different selectivity of NHA, VA and HBT towards lignin functional groups, despite the common N-OH moiety. C-5 condensed phenolic lignin groups were overall resistant to an LMS{sub NHA, HBT} treatments but to a lesser extent to an LMS{sub VA}. The inactiveness of these condensed lignin moieties was not observed when low-kappa kraft pulps were biobleached, suggesting that the LMS chemistry is influenced by the extent of delignification. We have also demonstrated that the current

The study shows the methodology and develops a case study on the refurbishment of an old building and discusses its outcome. The experiment on one side illustrates the utility of the analytical approach of FMEA and on the other side the difficulty to use different data and information to be considered in the durability evaluation carried out by the designer  based on the expert assessment. The role of the experts is to design a model and to assess the criticality of each event and to define the relationship between the causes and effects on building elements function. The designer has to define the environmental conditions of the site, the specifications of the material used, the skills of workmanship. The study has shown a quite realistic outcome and significant indications for the designer. Such a result suggests the development of the research.

    Hyougo-ken southern earthquake broke out in 1997/01/17. The Atomic Energy Safety Commission considered reasonable of the design guide for seismic design. And the Science and Technology Agency (STA) required reevaluation of atomic power facilities built by old design guide according to the new seismic design guide. JOYO obtained the construction license in 1970/02. Heat transport system and buildings of JOYO was re-evaluated by the new seismic design guide for the MK-III project. So, JOYO was not required re-evaluation by STA. But, this evaluation of MK-III was limited to reconstruction area, and the seismic design was reevaluated extensively to confirm earthquake proof characteristics. The structural integrity of buildings and equipments was confirmed by the result of reevaluation by the new seismic design guide. The analysis model conditions were established according to the 1987 and 1991 version of JEAG. This was done by ground investigation result and buildings vibration test. It was made clear that the analysis model conditions were reasonable and conservative from a technical view point. (author)

    There continues to be an increasing demand of electricity around the globe to fuel the industrial growth and to promote the human welfare. The economic activities have brought about richness in our material and cultural lives, in which process the electric power has been at the heart of the versatile energy sources. In order to timely and competitively respond to rapidly changing energy environment in the twenty-first century there is a growing need to build the advanced nuclear power plants in the unlimited workspace of virtual reality (VR) prior to commissioning. One can then realistically evaluate their construction time and cost per varying methods and options available from the leading-edge technology. In particular a great deal of efforts have yet to be made for time- and cost-dependent plant simulation and dynamically coupled database construction in the VR space. The operator training and personnel education may also benefit from the VR technology. The present work is being proposed in the three-dimensional space and time plus cost coordinates, i. e. four plus dimensional (4{sup +}D) coordinates. The 4{sup +}D VR application will enable the nuclear industry to narrow the technological gap from the other leading industries that have long since been employing the VR engineering. The 4{sup +}D technology will help nurture public understanding of the special discipline of nuclear power plants. The technology will also facilitate public access to the knowledge on the nuclear science and engineering which has so far been monopolized by the academia, national laboratories and the heavy industry. The 4{sup +}D virtual design and construction will open up the new horizon for revitalization of the nuclear industry over the globe in the foreseeable future. Considering the long construction and operation time for the nuclear power plants, the preliminary VR simulation capability for the plants will supply the vital information not only for the actual design and

  2. A Conceptual Framework for Managing Design Changes in Building Construction

    2016-01-01

    Full Text Available Design changes have always been an innate feature of the construction industry. Despite the various project management techniques, many building construction projects still fail to achieve their time and cost objectives. This paper aims to focus on design changes as a major cause of time delays and cost overruns. It seeks to discuss the causing factors of design changes in building construction projects and highlighting the resulting rework that is detrimental to project performance. Hence, this paper also aims to present a conceptual framework which was developed to better manage design changes through clued-up management decision to avoid future claims and disputes. Recent and current literature is examined and reviewed. The review approach was based on related literature to identified themes. The existing literature is summarised into five discrete themes of “design changes”, “rework”, “time and cost overruns”, “communication” and “decision-making”. The synthesised literature is subsequently utilised in the development of conceptual map which provided the direction for designing the conceptual framework. Extensive review of preceding studies on causes of time and cost overruns reveals that design changes is identified as one of the significant factors. However, there are limited studies in this domain. The discussion presents a knowledge gap of linking design changes and rework with decision-making in project management. This finding suggests the need for further empirical study. The framework stresses the importance of communication and management decision as the control mechanism. Researchers and practitioners in construction management field will find this study useful in understanding the causing factors of design changes and its detrimental impacts to project performance which risk the project to claims and disputes. The conceptual framework presents an imperative outcome to encourage further research in developing

    Modern science is a main driver of technological innovation. The efficiency of the scientific system is of key importance to ensure the competitiveness of a nation or region. However, the scientific system that we use today was devised centuries ago and is inadequate for our current ICT-based society: the peer review system encourages conservatism, journal publications are monolithic and slow, data is often not available to other scientists, and the independent validation of results is limited. The resulting scientific process is hence slow and sloppy. Building on the Innovation Accelerator paper by Helbing and Balietti [1], this paper takes the initial global vision and reviews the theoretical and technological building blocks that can be used for implementing an innovation (in first place: science) accelerator platform driven by re-imagining the science system. The envisioned platform would rest on four pillars: (i) Redesign the incentive scheme to reduce behavior such as conservatism, herding and hyping; (ii) Advance scientific publications by breaking up the monolithic paper unit and introducing other building blocks such as data, tools, experiment workflows, resources; (iii) Use machine readable semantics for publications, debate structures, provenance etc. in order to include the computer as a partner in the scientific process, and (iv) Build an online platform for collaboration, including a network of trust and reputation among the different types of stakeholders in the scientific system: scientists, educators, funding agencies, policy makers, students and industrial innovators among others. Any such improvements to the scientific system must support the entire scientific process (unlike current tools that chop up the scientific process into disconnected pieces), must facilitate and encourage collaboration and interdisciplinarity (again unlike current tools), must facilitate the inclusion of intelligent computing in the scientific process, must facilitate

    In 1994, the Bay Chapter of the Association of Energy Engineers{reg_sign} organized a two-day design charrette for energy-efficient redevelopment of buildings by the National Park Services (NPS) at the Presidio of San Francisco. This event brought together engineers, researchers, architects, government officials, and students in a participatory environment to apply their experience to create guidelines for the sustainable redesign of Presidio buildings. The venue for the charrette was a representative barracks building located at the Main Post of the Presidio. Examination of this building allowed for the development of design recommendations, both for the building and for the remainder of the facilities. The charrette was organized into a committee structure consisting of: steering, measurement and monitoring, modeling, building envelope and historic preservation (architectural), HVAC and controls, lighting, and presentation. Prior to the charrette itself, the modeling and measurement/monitoring committees developed substantial baseline data for the other committees during the charrette. An integrated design approach was initiated through interaction between the committees during the charrette. Later, committee reports were cross-referenced to emphasize whole building design and systems integration.

    Full Text Available With the development of sensor technologies, various application areas have emerged. The usage of these technologies and exploitation of recent improvements have clear benefits on building applications. Such use-cases can improve smart functions of buildings and can increase the end-user comfort. As a similar notion, building automation systems (BAS are smart systems that target to provide automated management of various control services and to improve resource usage efficiency. However, buildings generally contain hardware and control services from a diverse set of characteristics. The automated and central management of such functions can be challenging. In order to overcome such issues, an Emergency Evacuation Service is proposed for BAS, where requirements of such central management model are analyzed and model content and subservice definitions are prepared. A crucial scenario, which could be a necessity for future BAS, is defined and an approach for evacuation of people in the buildings at emergency situations is proposed. For real-life scenarios, the Evacuation Service is implemented by using a low-cost design, which is appropriate for Internet of Things (IoT based BAS applications. As demonstrated, the proposed service model can provide effective performance in real-life deployments.

    Small and medium commercial customers in California make up about 20-25% of electric peak load in California. With the roll out of smart meters to this customer group, which enable granular measurement of electricity consumption, the investor-owned utilities will offer dynamic prices as default tariffs by the end of 2011. Pacific Gas and Electric Company, which successfully deployed Automated Demand Response (AutoDR) Programs to its large commercial and industrial customers, started investigating the same infrastructures application to the small and medium commercial customers. This project aims to identify available technologies suitable for automating demand response for small-medium commercial buildings; to validate the extent to which that technology does what it claims to be able to do; and determine the extent to which customers find the technology useful for DR purpose. Ten sites, enabled by eight vendors, participated in at least four test AutoDR events per site in the summer of 2010. The results showed that while existing technology can reliably receive OpenADR signals and translate them into pre-programmed response strategies, it is likely that better levels of load sheds could be obtained than what is reported here if better understanding of the building systems were developed and the DR response strategies had been carefully designed and optimized for each site.

  9. Energy-efficient building design in cold climates: Schools as a case study

    Rangel Ruiz, Rocio

    Buildings account for great amounts of greenhouse gas emissions. In terms of energy, buildings account for one third of the total amount of energy used in the country every year! Schools account for 14 percent of the energy used annually in commercial and institutional buildings. Further, schools are one of the most commonly constructed building types in Canada and spaces such as classrooms are often duplicated. This makes them preferred candidates for the research that was undertaken where energy-efficient solutions that can be transferred to different school designs were derived. Throughout the study, the Commercial Building Incentive Program (CBIP) was used as a benchmark. The objectives of the study were to demonstrate energy-efficient concepts, provide a case study to evaluate solutions, develop typological models and provide an understanding of the innovation process. The technological and societal aspects of the energy-efficient design were addressed. With respect to the technological aspects, the first step was the analysis of conventional design using a school in Calgary as a case study. The optimization of conventional design was undertaken using computer modeling to identify best practice solutions. Aspects that were included in the studies were lighting design, envelope characteristics, HVAC systems and building plant systems. The inclusion of passive design included the analysis of daylighting and natural ventilation. Computer modeling was used to assess daylighting in classrooms with unilateral and bilateral daylighting. Illuminance levels, glare and light distribution were evaluated. The study of natural ventilation was undertaken using literature review. Airflow and outdoor temperatures were the focus to identify solutions that could be incorporated into the design of classrooms. It was concluded that achieving excellence in energy efficiency in schools could be achieved using readily available technologies. Energy savings of up to 63 percent better

    The proposed technology allows use of the latest microcircuit technology with lowest power and fastest speed, with minimal delay and engineering costs, through new Radiation Hardened by Design (RHBD) techniques that do not require extensive process characterization, technique evaluation and re-design at each Moore's Law generation. The separation of critical node groups is explicitly parameterized so it can be increased as microcircuit technologies shrink.

    1960s, American architect Paul · Suole proposed a new concept of green building. Green building is the product of modern society, and represents the direction of the building development in the new century. However, people strengthen the specific green building design technology to achieve green building in the long time, the building design process did not become the focus of green building design, the lag of process studies block the realization of multidisciplinary integrated green building design. In this paper, we research the concurrent design for green building design process from the design principle of green building, so as to provide methods to guide the practice of green building.%20世纪60年代,美国建筑师保罗·索勒瑞提出了绿色建筑的新理念。绿色建筑是现代社会的发展产物,代表了新世纪建筑发展的方向。但是国内人们长期以加强具体的绿色建筑设计技术应用来实现绿色建筑,过程设计没有成为绿色建筑设计的研究重点,过程研究的滞后阻碍了绿色建筑多学科整合设计的实现。本文从绿色建筑的设计原理出发,对于并行设计用于绿色建筑设计过程进行研究,从而为绿色建筑实践提供方法指导。

    2009-07-01

    This paper reported on the construction of the North House, a prototype solar-powered dwelling developed by a Canadian team for the 2009 Solar Decathlon. The prototype aims to develop a strategy for solar powered residential design that addresses the issues of how to build and live in the demanding northern context, how to design buildings that are adaptive to climate extremes and how new technologies and alternative energies can be used to create a viable and sustainable architecture. The occupant-focused design is meant to empower the occupants with both knowledge and control so that they can make intelligent choices and transform their own habits to live more sustainably. The residential occupant needs to operate as both user and manager of a green dwelling, and therefore requires specific information as well as access to help the building work more efficiently. The domestic environment is different from a workplace environment and therefore requires a unique means of control, display and integration with user lifestyle. The Adaptive Living Interface System for North House is based on interactive technologies that help occupants to both control the systems of the house while providing feedback on the operation of the house. The objective is to support behavioural transformation for energy saving living patterns. Once the competition is over, the North House will be reinstalled in Canada to undergo a minimum of 2 years of post-occupancy evaluation (POE) and testing. Both quantitative and qualitative data will be collected on energy performance, user livability, comfort and user satisfaction. Results were be measured against performance simulation during the design phase and will be used to provide feedback on simulation software. 11 refs., 5 figs.

    Evaluation of temperature development and related consumption of energy required for heating, air-conditioning, etc. in low-energy buildings requires the proper physical analysis, covering heat conduction, convection and radiation, including beam and diffusive components of solar radiation, on all building parts and interfaces. The system approach and the Fourier multiplicative decomposition together with the finite element technique offers the possibility of inexpensive and robust numerical and computational analysis of corresponding direct problems, as well as of the optimization ones with several design variables, using the Nelder-Mead simplex method. The practical example demonstrates the correlation between such numerical simulations and the time series of measurements of energy consumption on a small family house in Ostrov u Macochy (35 km northern from Brno).

  12. Procedural design of exterior lighting for buildings with complex constraints

    KAUST Repository

    Schwarz, Michael

    2014-09-23

    We present a system for the lighting design of procedurally modeled buildings. The design is procedurally specified as part of the ordinary modeling workflow by defining goals for the illumination that should be attained and locations where luminaires may be installed to realize these goals. Additionally, constraints can be modeled that make the arrangement of the installed luminaires respect certain aesthetic and structural considerations. From this specification, the system automatically generates a lighting solution for any concrete model instance. The underlying, intricate joint optimization and constraint satisfaction problem is approached with a stochastic scheme that operates directly in the complex subspace where all constraints are observed. To navigate this subspace efficaciously, the actual lighting situation is taken into account. We demonstrate our system on multiple examples spanning a variety of architectural structures and lighting designs. Copyright held by the Owner/Author.

    Full Text Available Previous researches show that incorporating natural elements in design has proven a significant result in balancing building indoor environment. Using plant as part of the design has been widely accepted to contribute good thermal impact as shown in bioclimatic design, green roofing system and living wall elements. As there are so many species of plants for selection, this research was carried out to analyze types of indoor plants that have the potential to contribute thermal comfort to their surrounding. Based on the fact that plant leaves are the part where transpiration and guttation take place, plants are categorized into seven types based on their leaves architecture. They were then tested on their impact on surrounding temperature and humidity. Result shows that Linear, Lanceolate and Oblong shaped leaves categories are good in lowering the relative humidity while the categories that are good in lowering the temperature are Linear, Lanceolate, Cordate and Oblong shaped leaves categories. The study was carried out through series of relative humidity and air temperature monitoring of several room casings that consist with the plants. Both relative humidity and air temperature of the rooms with plants were recorded lower compared with the one without plant. Different categories of plants do give good result in relative humidity and air temperature. Thus, with a good combination of plant installation inside or onto building, it may contribute towards providing a good thermal comfort to the occupants.

    Low Power Consumption is one of the critical issues in the performance of small battery-powered handheld devices. Mobile terminals feature an ever increasing number of wireless communication alternatives including GPS, Bluetooth, GSM, 3G, WiFi or DVB-H. Considering that the total power available for each terminal is limited by the relatively slow increase in battery performance expected in the near future, the need for efficient circuits is now critical. This book presents the basic techniques available to design low power RF CMOS analogue circuits. It gives circuit designers a complete guide of alternatives to optimize power consumption and explains the application of these rules in the most common RF building blocks: LNA, mixers and PLLs. It is set out using practical examples and offers a unique perspective as it targets designers working within the standard CMOS process and all the limitations inherent in these technologies.

Project Description Native Village of Port Graham (NVPG) completed preconstruction activities that pave the way towards reduced local energy costs through the construction and operations of a cord wood biomass heating system. NVPG plans include installation of a GARN WHS 3200 Boiler that uses cord wood as fuel source. Implementation of the 700,000 Btu per hour output biomass community building heat utility would heat 5-community buildings in Port Graham, Alaska. Heating system is estimated to displace 85% of the heating fuel oil or 5365 gallons of fuel on an annual basis with an estimated peak output of 600,000 Btu per hour. Estimated savings is $15,112.00 per year. The construction cost estimate made to install the new biomass boiler system is estimated $251,693.47 with an additional Boiler Building expansion cost estimated at $97,828.40. Total installed cost is estimated $349,521.87. The WHS 3200 Boiler would be placed inside a new structure at the old community Water Plant Building site that is controlled by NVPG. Design of the new biomass heat plant and hot water loop system was completed by Richmond Engineering, NVPG contractor for the project. A hot water heat loop system running off the boiler is designed to be placed underground on lands controlled by NVPG and stubbed to feed hot water to existing base board heating system in the following community buildings: 1.

    Energy Technology Data Exchange (ETDEWEB)

    Scheib, J.; Pless, S.; Torcellini, P.

    2014-08-01

    NREL experienced a significant increase in employees and facilities on our 327-acre main campus in Golden, Colorado over the past five years. To support this growth, researchers developed and demonstrated a new building acquisition method that successfully integrates energy efficiency requirements into the design-build requests for proposals and contracts. We piloted this energy performance based design-build process with our first new construction project in 2008. We have since replicated and evolved the process for large office buildings, a smart grid research laboratory, a supercomputer, a parking structure, and a cafeteria. Each project incorporated aggressive efficiency strategies using contractual energy use requirements in the design-build contracts, all on typical construction budgets. We have found that when energy efficiency is a core project requirement as defined at the beginning of a project, innovative design-build teams can integrate the most cost effective and high performance efficiency strategies on typical construction budgets. When the design-build contract includes measurable energy requirements and is set up to incentivize design-build teams to focus on achieving high performance in actual operations, owners can now expect their facilities to perform. As NREL completed the new construction in 2013, we have documented our best practices in training materials and a how-to guide so that other owners and owner's representatives can replicate our successes and learn from our experiences in attaining market viable, world-class energy performance in the built environment.

    Directory of Open Access Journals (Sweden)

    Andrea Campioli

    2011-04-01

    Full Text Available Architectural redevelopment and the revival of the construction sector are conditional on the incentivisation and bolstering of innovation processes. Thus the partial declensions that have been attached to these processes over the last few years have seen research and experimentation being tailored to the spectacularisation of shapes or the hidden performance optimisation of materials and components. Genuine improvement in the quality of architecture and its construction in this day and age depends on the abilities of designers to adopt the entire life cycle of buildings as a reference framework and on the willingness of all those working in the construction supply chain to activate virtuous cooperation.

  12. Evaluation of a Mixed Method Approach for Studying User Interaction with Novel Building Control Technology

    Directory of Open Access Journals (Sweden)

    Birgit Painter

    2016-03-01

    Full Text Available Energy-efficient building performance requires sophisticated control systems that are based on realistic occupant behaviour models. To provide robust data for the development of these models, research studies in real-world settings are needed. Yet, such studies are challenging and necessitate careful design in terms of data collection methods and procedures. This paper describes and critiques the design of a mixed methods approach for occupant behaviour research. It reviews the methodology developed for a longitudinal study in a real-world office environment where occupants’ experience with a novel facade technology (electrochromic glazing was investigated. The methodology integrates objective physical measurements, observational data and self-reported experience data. Using data from one day of the study, this paper illustrates how the different sources can be combined in order to derive an in-depth understanding of the interplay between external daylight conditions, characteristics of the facade technology, occupant interaction with the technology and the resulting occupant experience. It was found that whilst the individual methods may be affected by practical limitations, these can be partially offset by combining physical measurements and observations with self-reported data. The paper critically evaluates the individual techniques, as well as the benefits of their integration and makes recommendations for the design of future occupant behaviour studies in real-world settings.

  13. Bringing simulation to implementation: Presentation of a global approach in the design of passive solar buildings under humid tropical climates

    CERN Document Server

    Garde, François; Celaire, Robert

    2012-01-01

    In early 1995, a DSM pilot initiative has been launched in the French islands of Guadeloupe and Reunion through a partnership between several public and private partners (the French Public Utility EDF, the University of Reunion Island, low cost housing companies, architects, energy consultants, etc...) to set up standards to improve thermal design of new residential buildings in tropical climates. This partnership led to defining optimized bio-climatic urban planning and architectural designs featuring the use of passive cooling architectural principles (solar shading, natural ventilation) and components, as well as energy efficient systems and technologies. The design and sizing of each architectural component on internal thermal comfort in building has been assessed with a validated thermal and airflow building simulation software (CODYRUN). These technical specifications have been edited in a reference document which has been used to build over 300 new pilot dwellings through the years 1996-1998 in Reunion...

  15. Applicability research on passive design of residential buildings in hot summer and cold winter zone in China

    Science.gov (United States)

    Zhang, Hui; Wang, Huihui; Zhou, Xuan

    2017-04-01

    Passive design has long been a concern as an effective way of building energy efficiency. However, different urban climate characteristics determine the time-effectiveness of passive design. According to the climate characteristics of hot summer and cold winter zone in China, this research chose five cities, Shanghai, Wuhan, Chongqing, Nanjing and Changsha, to analyze their residential building energy consumption and thermal environment conditions. Based on Weather Tool calculation and analysis, the purpose of this research is to put forward the concept of Suitable Degree (SD), namely the applicability of the passive design. In addition, five cities’ SD of passive design technology had been analyzed from aspect of ventilation, temperature, solar radiation and envelope, then passive design strategies and methods of five cities’ residential building were discussed.

    Costella, M. [Elemento 5 Bioclimatic and Environmental Design, Chapeco (Brazil)

    2009-07-01

    This paper reported on a study in which a 2-storey office building was constructed using traditional and contemporary techniques and technologies to provide acceptable summer and winter thermal comfort. The design included the use of passive and hybrid cooling and heating techniques to decrease cooling and heating energy consumption and to improve thermal comfort. The design guidelines were based on the climate in Chapeco, Brazil in terms of annual mean temperature, relative humidity, wind speed and cloudiness. Passive strategies that respond to climate were used in the design, including natural daylighting; natural ventilation; solar heating and thermal mass; shading devices; and green roofs. The relationships between buildings and outdoor spaces were also controlled in order to ensure a response to the different seasons. This study showed that an environmental design approach goes far beyond the quantification of energy consumption through the use of different materials or strategies. The occupant's thermal and psychological comforts were placed as the main issues to be addressed and not energy savings. Once completed, the building will be monitored to determine if the passive strategies are working. 4 refs., 14 figs.

    Costs and benefits of building energy efficiency are estimated as a means of reducing greenhouse gas emissions in Pittsburgh, PA and Austin, TX. The analysis includes electricity and natural gas consumption, covering 75% of building energy consumption in Pittsburgh and 85% in Austin. Two policy objectives were evaluated: maximize GHG reductions given initial budget constraints or maximize social savings given target GHG reductions. This approach evaluates the trade-offs between three primary and often conflicting program design parameters: initial capital constraints, social savings, and GHG reductions. Results suggest uncertainty in local stocks, demands, and efficiency significantly impacts anticipated outcomes. Annual GHG reductions of 1 ton CO{sub 2} eq/capita/yr in Pittsburgh could cost near nothing or over $20 per capita annually. Capital-constrained policies generate slightly less social savings (a present value of a few hundred dollars per capita) than policies that maximize social savings. However, sectors and end uses targeted for intervention vary depending on policy objectives and constraints. Optimal efficiency investment strategies for some end uses vary significantly (in excess of 100%) between Pittsburgh and Austin, suggesting that resources and guidance conducted at the national scale may mislead state and local decision-makers. Results are used to provide recommendations for efficiency program administrators. - Highlights: > We use public data to estimate local building energy costs, benefits and greenhouse gas reductions. > We use optimization to evaluate trade-offs between program objectives and capital constraints. > Local energy market conditions significantly influence efficiency expectations. > Different program objectives can lead to different effective investment strategies. > We reflect on the implications of our results for efficiency program design.

  18. Object-oriented software design in semiautomatic building extraction

    Guelch, Eberhard; Mueller, Hardo

    1997-08-01

    Developing a system for semiautomatic building acquisition is a complex process, that requires constant integration and updating of software modules and user interfaces. To facilitate these processes we apply an object-oriented design not only for the data but also for the software involved. We use the unified modeling language (UML) to describe the object-oriented modeling of the system in different levels of detail. We can distinguish between use cases from the users point of view, that represent a sequence of actions, yielding in an observable result and the use cases for the programmers, who can use the system as a class library to integrate the acquisition modules in their own software. The structure of the system is based on the model-view-controller (MVC) design pattern. An example from the integration of automated texture extraction for the visualization of results demonstrate the feasibility of this approach.

    Science.gov (United States)

    Eckman, Molly; Gorski, Irena; Mehta, Khanjan

    Mobile health, or mHealth, technology has the potential to improve health care access in the developing world. However, the majority of mHealth projects do not expand beyond the pilot stage. A core reason why is because they do not account for the individual needs and wants of those involved. A collaborative approach is needed to integrate the perspectives of all stakeholders into the design and operation of mHealth endeavours. Design thinking is a methodology used to develop and evaluate novel concepts for systems. With roots in participatory processes and self-determined pathways, design thinking provides a compelling framework to understand and apply the needs of diverse stakeholders to mHealth project development through a highly iterative process. The methodology presented in this article provides a structured approach to apply design thinking principles to assess the feasibility of novel mHealth endeavours during early conceptualisation.

    Native Village of Port Graham completed preconstruction activities to prepare for construction and operations of a cord wood biomass heating system to five or more community buildings in Port Graham, Alaska. Project Description Native Village of Port Graham (NVPG) completed preconstruction activities that pave the way towards reduced local energy costs through the construction and operations of a cord wood biomass heating system. NVPG plans include installation of a GARN WHS 3200 Boiler that uses cord wood as fuel source. Implementation of the 700,000 Btu per hour output biomass community building heat utility would heat 5-community buildings in Port Graham, Alaska. Heating system is estimated to displace 85% of the heating fuel oil or 5365 gallons of fuel on an annual basis with an estimated peak output of 600,000 Btu per hour. Estimated savings is $15,112.00 per year. The construction cost estimate made to install the new biomass boiler system is estimated $251,693.47 with an additional Boiler Building expansion cost estimated at $97,828.40. Total installed cost is estimated $349,521.87. The WHS 3200 Boiler would be placed inside a new structure at the old community Water Plant Building site that is controlled by NVPG. Design of the new biomass heat plant and hot water loop system was completed by Richmond Engineering, NVPG contractor for the project. A hot water heat loop system running off the boiler is designed to be placed underground on lands controlled by NVPG and stubbed to feed hot water to existing base board heating system in the following community buildings: 1. Anesia Anahonak Moonin Health and Dental Clinic 2. Native Village of Port Graham offices 3. Port Graham Public Safety Building/Fire Department 4.

    This paper describes an application of the fundamental methods of physics to solve a problem of environmental and economic interest: the description of the thermal performance of passive solar buildings. Such a description is of great practical interest to building designers; however, this paper is not intended to be of use to architects and engineers in its present form. Its intention is to provide a theoretical basis for understanding passive solar buildings; further effort is needed to develop rules of solar engineering.

    The objective of this paper is to explicate on the study of modern administrative building in Malaysia which portrays regional design approach that conforms to the local context and climate by reviewing two case studies; Perdana Putra (1999) and former Prime Minister's Office (1967). This paper is significant because the country's stature and political statement was symbolized by administrative building as a national icon. In other words, it is also viewed as a cultural object that is closely tied to a particular social context and nation historical moment. Administrative building, therefore, may exhibit various meanings. This paper uses structuralism paradigm and semiotic principles as a methodological approach. This paper is of importance for practicing architects and society in the future as it offers new knowledge and understanding in identifying the suitable climatic consideration that may reflect regionalist design approach in modern administrative building. These elements then may be adopted in designing public buildings in the future with regional values that are important for expressing national culture to symbolize the identity of place and society as well as responsive to climate change.

    2010-12-01

    Full Text Available This paper examines theoretical, pedagogical, and technological differences between two technologies that have been used in undergraduate interprofessional health sciences at the University of Toronto. One, a learning management system, WebCT 2.0, supports online coursework. The other, a Knowledge Building environment, Knowledge Forum 2.0, supports the collaborative work of knowledge-creating communities. Seventy students from six health science programs (Dentistry, Medicine, Nursing, Occupational Therapy, Pharmacy and Physical Therapy participated online in a 5-day initiative to advance understanding of core principles and professional roles in pain assessment and management. Knowledge Forum functioned well as a learning management system but to preserve comparability between the two technologies its full resources were not brought into play. In this paper we examine three distinctive affordances of Knowledge Forum that have implications for health sciences education: (1 supports for Knowledge Building discourse as distinct from standard threaded discourse; (2 integration of sociocognitive functions as distinct from an assortment of separate tools; and (3 resources for multidimensional social and cognitive assessment that go beyond common participation indicators and instructor-designed quizzes and analyses. We argue that these design characteristics have the potential to open educational pathways that traditional learning management systems leave closed.

  11. Commentary: Risk Management and Reliability Design for Buildings

    Energy Technology Data Exchange (ETDEWEB)

    Berry, Dennis L.; Cranwell, Robert M.; Hunter, Regina L.

    1999-05-28

    Where there is a significant actuarial basis for decision making (e.g., the occurrence of fires in single-family dwellings), there is little incentive for formal risk management. Formal risk assessments are most useful in those cases where the value of the structure is high, many people may be affected, the societal perception of risk is high, consequences of a mishap would be severe, and the actuarial uncertainty is large. For these cases, there is little opportunity to obtain the necessary experiential data to make informed decisions, and the consequences in terms of money, lives, and societal confidence are severe enough to warrant a formal risk assessment. Other important factors include the symbolic value of the structure and vulnerability to single point failures. It is unlikely that formal risk management and assessment practices will or should replace the proven institutions of building codes and engineering practices. Nevertheless, formal risk assessment can provide valuable insights into the hazards threatening high-value and high-risk (perceived or actual) buildings and structures, which can in turn be translated into improved public health, safety, and security. The key is to choose and apply the right assessment tool to match the structure in question. Design-for-reliability concepts can be applied to buildings, bridges, transportation sys- tems, dams, and other structures. The use of these concepts could have the dual benefits of lowering life-cycle costs by reducing the necessity for maintenance and repair and of enhancing the saiiety and security of the structure's users.

    Time-dependent structure analysis theory has been proved to be more accurate and reliable com-pared to commonly used methods during construction. However, so far applications are limited to partial pe-riod and part of the structure because of immeasurable artificial intervention. Based on the building informa-tion model (BIM) and four-dimensional (4D) technology, this paper proposes an improves structure analysis method, which can generate structural geometry, resistance model, and loading conditions automatically by a close interlink of the schedule information, architectural model, and material properties. The method was applied to a safety analysis during a continuous and dynamic simulation of the entire construction process.The results show that the organic combination of the BIM, 4D technology, construction simulation, and safety analysis of time-dependent structures is feasible and practical. This research also lays a foundation for further researches on building lifecycle management by combining architectural design, structure analy-sis, and construction management.

    2006-09-01

    Commercial buildings account for a large portion of summer peak electric demand. Research results show that there is significant potential to reduce peak demand in commercial buildings through advanced control technologies and strategies. However, a better understanding of commercial buildings contribution to peak demand and the use of energy management and control systems is required to develop this demand response resource to its full potential. The main objectives of the study were: (1) To evaluate the size of contributions of peak demand commercial buildings in the U.S.; (2) To understand how commercial building control systems support energy efficiency and DR; and (3) To disseminate the results to the building owners, facility managers and building controls industry. In order to estimate the commercial buildings contribution to peak demand, two sources of data are used: (1) Commercial Building Energy Consumption Survey (CBECS) and (2) National Energy Modeling System (NEMS). These two sources indicate that commercial buildings noncoincidental peak demand is about 330GW. The project then focused on technologies and strategies that deliver energy efficiency and also target 5-10% of this peak. Based on a building operations perspective, a demand-side management framework with three main features: (1) daily energy efficiency, (2) daily peak load management and (3) dynamic, event-driven DR are outlined. A general description of DR, its benefits, and nationwide DR potential in commercial buildings are presented. Case studies involving these technologies and strategies are described. The findings of this project are shared with building owners, building controls industry, researchers and government entities through a webcast and their input is requested. Their input is presented in the appendix section of this report.

    2002-01-01

    The word "space" has always been associated with and had a profound impact upon architectural design. Until relatively recently, however, the term has been used in a different sense to that understood by the aerospace community - for them, space was less abstract, more concrete and used in the context of space flight and space exploration, rather than, say, an empty area or space requiring to be filled by furniture. However, the two senses of the word space have now converged to some extent. Interior designers and architects have been involved in designing the interior of Skylab, the structure of the International Space Station, and futuristic space hotels. Today, architects are designing, and builders are building, houses, offices and other structures which incorporate a plethora of new technologies, materials and production processes in an effort not only to introduce innovative and adventurous ideas but also in an attempt to address environmental and social issues. Foremost among these new technologies and materials being considered today are those that have been developed for and by the space industry. This paper examines some of these space technologies, such as energy efficient solar cells, durable plastics, air and water filtration techniques, which have been adapted to both provide power while reducing energy consumption, conserve resources and so on. Several of these technologies have now been employed by the European Space Agency to develop a Space House TM - the first of its kind, which will be deployed not so much on planets like Mars, but rather here on Earth. The Space House TM, which exhibits many innovative features such as high strength light-weight carbon composites, active noise-damped, (glass and plastic) windows, low-cost solar arrays and latent heat storage, air and water purification systems will be described.

    2004-01-01

    A new Web software architecture, NumberLinX (NLX), has been integrated into a commercial Web design program to produce a drag-and-drop environment for building interactive simulations. NLX is a library of reusable objects written in Java, including input, output, calculation, and control objects. The NLX objects were added to the palette of available objects in the Web design program to be selected and dropped on a page. Inserting an object in a Web page is accomplished by adding a template block of HTML code to the page file. HTML parameters in the block must be set to user-supplied values, so the HTML code is generated dynamically, based on user entries in a popup form. Implementing the object inspector for each object permits the user to edit object attributes in a form window. Except for model definition, the combination of the NLX architecture and the Web design program permits construction of interactive simulation pages without writing or inspecting code.

However since no design optimization for an entire building exists, a significant degree of uncertainty is involved in design decisions. The aim of this paper is to present the brute force optimization process which is a method removing the uncertainty from green building designs. This method relies on the selection of optimization criteria and then several simulations are performed. A demonstration pilot was carried out in Toronto and over one million design permutations were conducted. Results showed that parameters such as total building area, window performance and infiltration level are the most important to the lifetime energy consumption of a building. This study pointed out the important parameters to optimize in order to reduce a building's energy consumption.

    Full Text Available There are many iconic high rise buildings in Hong Kong, for example, International Commercial Centre, International Financial Centre, etc. Fire safety issue in high rise buildings has been raised by local fire professionals in terms of occupant evacuation, means of fire-fighting by fire fighters, sprinkler systems to automatically put off fires in buildings, etc. Fire risk becomes an important issue in building fire safety because it relates to life safety of building occupants where they live and work in high rise buildings in Hong Kong. The aim of this research is to identify the fire risk for different types of high rise buildings in Hong Kong and to optimise the fire prevention management for those high rise buildings with higher level of fire risk and to validate the model and also to carry out the study of the conflict between the current fire safety building code and the current trend of green building design. Survey via the 7-point scale questionnaire was conducted through 50 participants and their responses were received and analysed via the statistical tool SPSS software computer program. A number of statistical methods of testing for significantly difference in samples were adopted to carry out the analysis of the data received. When the statistical analysis was completed, the results of the data analysis were validated by two Fire Safety Experts in this area of specialisation and also by quantitative fire risk analysis.

  8. Building America Case Study: Field Trial of an Aerosol-Based Enclosure Sealing Technology, Clovis, California

    Energy Technology Data Exchange (ETDEWEB)

    2016-05-01

    This report presents the results from several demonstrations of a new method for sealing building envelope air leaks using an aerosol sealing process developed by the Western Cooling Efficiency Center at UC Davis. The process involves pressurizing a building while applying an aerosol sealant to the interior. As air escapes through leaks in the building envelope, the aerosol particles are transported to the leaks where they collect and form a seal that blocks the leak. Standard blower door technology is used to facilitate the building pressurization, which allows the installer to track the sealing progress during the installation and automatically verify the final building tightness. Each aerosol envelope sealing installation was performed after drywall was installed and taped, and the process did not appear to interrupt the construction schedule or interfere with other trades working in the homes. The labor needed to physically seal bulk air leaks in typical construction will not be replaced by this technology. However, this technology is capable of bringing the air leakage of a building that was built with standard construction techniques and HERS-verified sealing down to levels that would meet DOE Zero Energy Ready Homes program requirements. When a developer is striving to meet a tighter envelope leakage specification, this technology could greatly reduce the cost to achieve that goal by providing a simple and relatively low cost method for reducing the air leakage of a building envelope with little to no change in their common building practices.

This paper reviews current design practice and tools for designing NZESBs through a literature review and a survey. It also discusses modelling issues and presents the procedure used in several redesign and optimization case studies of...

  15. Designing institutions for climate change: Why rational design involves technology

    Energy Technology Data Exchange (ETDEWEB)

    Coninck, H. de [Energy Research Centre of the Netherlands, Petten (Netherlands)

    2008-09-30

    This paper aims to explore how to augment the institutional solutions offered by current political theory for addressing the unprecedented problem of climate change. Although steering directly at emission reductions in an international treaty has benefits in terms of cost-effectiveness, the paper arrives at the conclusion that considerations around technological development should be drawn into the treaty equation in order to generate sufficient reciprocity to have a politically feasible international regime. It then argues that the benefits of technology agreements for climate change mitigation may be larger than commonly assumed, as they - if properly designed - could lead to real emission reductions and provide more flexibility to reach agreement in post-2012 negotiations than proposals modelled exclusively on the Kyoto Protocol or other types of absolute emission targets. Based on rational design of international institutions for environmental governance, and attempting to take into account considerations of technological dynamics and the 'sociotechnical system', contours of a possible environmentally effective and politically feasible international climate change agreements are sketched.

  20. Power generation from thermoelectric system-embedded Plexiglas for green building technology

    KAUST Repository

    Inayat, Salman Bin

    2012-06-09

    Thermoelectric materials embedded through or inside exterior glass windows can act as a viable source of supplemental power in geographic locations where hot weather dominates. This thermoelectricity is generated because of the thermal difference between the high temperature outside and the relatively cold temperature inside. Using physical vapor deposition process, we experimentally verify this concept by embedding bismuth telluride and antimony telluride through the 5 mm Plexiglas to demonstrate 10 nW of thermopower generation with a temperature gradient of 21 °C. Albeit tiny at this point with non-optimized design and development, this concept can be extended for relatively large-scale power generation as an additional power supply for green building technology.
