    The energy world crisis of 1973 besides the problems of supplying and the raise of prices also propitiated in various countries, a reaction aimed at the efficient use and conservation of energy and to the application of a common sense architecture: the BIOCLIMATIC ARCHITECTURE, which is based in utilization in the buildings of the alternate energies, such as the wind power, etc. The obtaining natural environmental comfort conditions and the saving and efficient use of energy in the buildings are the fundamental objectives of the BIOCLIMATIC ARCHITECTURE. Under these considerations several passive systems for the thermal control in buildings have been set forth, which have been applied in different climatic regions of the planet. This paper presents and analyzes the potential saving of energy through the implementation of practices such as the installation of artificial high efficiency lighting systems and passive cooling systems for the thermal control of an educational building -the central library of the Universidad Autonoma Metropolitana, Azcapotzalco Unit, located in Mexico City. The objective of this study is aimed at the reduction of the consumption of energy in the library and the attainment of comfortable hygrothermal environment for its occupants. Studies performed during the first stage of the research, have permitted the identification of a excessive energy consumption and lack of comfort hygrothermal conditions and the need of high quality air inside the library. These actions have been focussed to two aspects. The first one is related to the improvement in the operation of the electric installation and in the library lighting. These actions were based in the substitution of lamps, load balancing of the secondary circuits, checking and improvement of the electric insulation a better selectivity of lighting switches installation in the vicinity of windows and areas with greater natural illumination.

    In order to contribute to the sustainability of the outdoor environment, knowledge about the urban thermal bioclimate should be transferred into climatic guidelines for planning. The general framework of this study responds to the need of analyzing thermal bioclimate in Mediterranean climate regions and its influence as an urban design factor. The paper analyzes the background of the urban climate and thermal bioclimate conditions in Barcelona (Spain), through the effect of shade conditions and wind speed variations. Simulations of shade and wind speed variations were performed to evaluate changes in thermal bioclimate due to modifications in urban morphology. Air temperature, relative humidity, wind speed, and solar radiation for the period from January, 2001 to January, 2015 were used to calculate physiologically equivalent temperature (PET) using the RayMan model. The results demonstrate that shade is the most important strategy to improve urban microclimatic conditions. In Barcelona, human thermal comfort conditions can be improved by shade and wind speed increase in terms of PET above 23 °C and by a wind speed decrease for thresholds of PET below 18 °C. Heat stress situations can be mitigated by shade and wind speed increase in conditions above 35 and 45 °C, respectively. The results of the study are an important contribution for urban planners, due to their possibilities and potential for the description of microclimatic conditions in Mediterranean climate regions. The knowledge is useful for improved human thermal comfort conditions, from the suitable configuration of urban form and architecture.

    Tools and criteria for Cost-Benefit Analysis (ACB) of energy saving in bioclimatic designs (DB) are presented, for which a reference project is established. Based on the traditional design of air conditioning of a building and with the support of this one, the estimation of costs and benefits of the same building is made; but with passive systems. The tools used consider related resources such as time and money. Criteria are used such as: Present value (VP), Equivalent Annual Cost (EAC) and the Cost of the conserved Energy (CEC). The costs related to the construction, maintenance and operation of the design are taken into consideration. The differences between the design of reference and the Bioclimatic Design, established from the application of these criteria, allow evaluating the economic margin as far as operation and maintenance. Finally, the cost of the conserved energy of the bioclimatic measures is evaluated as an initiative for energy saving and calculates the present value from them in all of the period of useful life of the bioclimatic design.

    International Nuclear Information System (INIS)

    2001-01-01

    The BIOCLIM project on modelling sequential Biosphere systems under Climate change for radioactive waste disposal is part of the EURATOM fifth European framework programme. The project was launched in October 2000 for a three-year period. The project aims at providing a scientific basis and practical methodology for assessing the possible long term impacts on the safety of radioactive waste repositories in deep formations due to climate and environmental change. The project brings together a number of representatives from both European radioactive waste management organisations which have national responsibilities for the safe disposal of radioactive waste, either as disposers or regulators, and several highly experienced climate research teams. In particular, BIOCLIM aims to address the important objective of how to represent the development of future biosphere systems by addressing both how to model long-term climate change, the relevant environmental consequences of such changes and the implementation of a sequential approach to such changes. The results from the development of this sophisticated approach will be of great benefit for improving long term radiological impact calculations and the information presented in a safety case. Simulations will be conducted to represent the time series of long-term climate in three European areas within which disposal sites may be established (i.e. Central/Southern Spain, Northeast of France and Central Britain). Two complementary strategies will provide representations of future climate predictions together with associated vegetation patterns using either an analysis of distinct climate states or a continuous climate simulation over at least one glacial-interglacial cycle and possibly for other selected periods over the next 1,000,000 years. These results will be used to derive the characteristics of possible future human environments (i.e. biosphere systems) through which radionuclides, emerging from the repository, may

    2014-01-01

    Among several urban design parameters, the height-to-width ratio (H/W) and orientation are important parameters strongly affecting thermal conditions in cities. This paper quantifies changes in thermal comfort due to typical urban canyon configurations in Campinas, Brazil, and presents urban guidelines concerning H/W ratios and green spaces to adapt urban climate change. The study focuses on thermal comfort issues of humans in urban areas and performs evaluation in terms of physiologically equivalent temperature (PET), based on long-term data. Meteorological data of air temperature, relative humidity, wind speed and solar radiation over a 7-year period (2003-2010) were used. A 3D street canyon model was designed with RayMan Pro software to simulate the influence of urban configuration on urban thermal climate. The following configurations and setups were used. The model canyon was 500 m in length, with widths 9, 21, and 44 m. Its height varied in steps of 2.5 m, from 5 to 40 m. The canyon could be rotated in steps of 15°. The results show that urban design parameters such as width, height, and orientation modify thermal conditions within street canyons. A northeast-southwest orientation can reduce PET during daytime more than other scenarios. Forestry management and green areas are recommended to promote shade on pedestrian areas and on façades, and to improve bioclimate thermal stress, in particular for H/W ratio less than 0.5. The method and results can be applied by architects and urban planners interested in developing responsive guidelines for urban climate issues.

  14. Bioclim Deliverable D8b: development of the physical/statistical down-scaling methodology and application to climate model Climber for BIOCLIM Work-package 3

    International Nuclear Information System (INIS)

    2003-01-01

    The overall aim of BIOCLIM is to assess the possible long term impacts due to climate change on the safety of radioactive waste repositories in deep formations. The main aim of this deliverable is to provide time series of climatic variables at the high resolution as needed by performance assessment (PA) of radioactive waste repositories, on the basis of coarse output from the CLIMBER-GREMLINS climate model. The climatological variables studied here are long-term (monthly) mean temperature and precipitation, as these are the main variables of interest for performance assessment. CLIMBER-GREMLINS is an earth-system model of intermediate complexity (EMIC), designed for long climate simulations (glacial cycles). Thus, this model has a coarse resolution (about 50 degrees in longitude) and other limitations which are sketched in this report. For the purpose of performance assessment, the climatological variables are required at scales pertinent for the knowledge of the conditions at the depository site. In this work, the final resolution is that of the best available global gridded present-day climatology, which is 1/6 degree in both longitude and latitude. To obtain climate-change information at this high resolution on the basis of the climate model outputs, a 2-step down-scaling method is designed. First, physical considerations are used to define variables which are expected to have links which climatological values; secondly a statistical model is used to find the links between these variables and the high-resolution climatology of temperature and precipitation. Thus the method is termed as 'physical/statistical': it involves physically based assumptions to compute predictors from model variables and then relies on statistics to find empirical links between these predictors and the climatology. The simple connection of coarse model results to regional values can not be done on a purely empirical way because the model does not provide enough information - it is both

Algunas de las estrategias para darle solucion a esta problematica son: disminuir del area de lucernarios, cambiar las luminarias existentes, aumentar la ventilacion, implementar canceleria, etc. Con los resultados obtenidos nace la esperanza de que se utilicen estrategias de diseno bioclimatico para ahorrar energia en otros edificios, ya que muchas veces las edificaciones poseen un diseno que unicamente provoca el uso imprudente de la energia.

  18. Bioclim Deliverable D6b: application of statistical down-scaling within the BIOCLIM hierarchical strategy: methods, data requirements and underlying assumptions

    International Nuclear Information System (INIS)

    2004-01-01

    The overall aim of BIOCLIM is to assess the possible long term impacts due to climate change on the safety of radioactive waste repositories in deep formations. The coarse spatial scale of the Earth-system Models of Intermediate Complexity (EMICs) used in BIOCLIM compared with the BIOCLIM study regions and the needs of performance assessment creates a need for down-scaling. Most of the developmental work on down-scaling methodologies undertaken by the international research community has focused on down-scaling from the general circulation model (GCM) scale (with a typical spatial resolution of 400 km by 400 km over Europe in the current generation of models) using dynamical down-scaling (i.e., regional climate models (RCMs), which typically have a spatial resolution of 50 km by 50 km for models whose domain covers the European region) or statistical methods (which can provide information at the point or station scale) in order to construct scenarios of anthropogenic climate change up to 2100. Dynamical down-scaling (with the MAR RCM) is used in BIOCLIM WP2 to down-scale from the GCM (i.e., IPSL C M4 D ) scale. In the original BIOCLIM description of work, it was proposed that UEA would apply statistical down-scaling to IPSL C M4 D output in WP2 as part of the hierarchical strategy. Statistical down-scaling requires the identification of statistical relationships between the observed large-scale and regional/local climate, which are then applied to large-scale GCM output, on the assumption that these relationships remain valid in the future (the assumption of stationarity). Thus it was proposed that UEA would investigate the extent to which it is possible to apply relationships between the present-day large-scale and regional/local climate to the relatively extreme conditions of the BIOCLIM WP2 snapshot simulations. Potential statistical down-scaling methodologies were identified from previous work performed at UEA. Appropriate station data from the case

    Full Text Available El microclima urbano es la resultante de una interacción entre la morfología urbana y el medio ambiente; y su estudio importa porque determina las condiciones de confort térmico en los espacios exteriores a la vivienda y por tanto su uso. Se parte del supuesto que la evaluación energética del entorno urbano no se considera en la actividad proyectual de conjuntos habitacionales. Por ello, el objetivo principal de esta tesis fue investigar el comportamiento energético de tejidos urbanos residenciales contemporáneos, aplicado a dos modelos de habitar: la ciudad jardín y la ciudad de bloque. Se postuló que si a una configuración espacial dada, le corresponde un comportamiento energético singular, entonces sería posible descifrar un patrón morfo-climático. El urbanismo bioclimático enmarca el enfoque teórico de la discusión, y el trabajo de campo se situó en un barrio residencial del pericentro en la metrópolis de Santiago de Chile. El método de caso analizó las dos tipologías de tejidos e integró los parámetros bioclimáticos: temperatura del aire, humedad relativa, radiación solar, y vientos para evaluar su desempeño energético. Los resultados demostraron que el rendimiento energético de los tejidos urbanos variaba según la tipología y con ello fue posible descifrar un patrón bioclimático. Este conocimiento es aplicable a la planificación y al diseño urbano sostenible. Abstract: Urban microclimate is a result of interaction between urban morphology and environment at micro-scale. Its study relevance lies on thermal comfort in outdoor spaces so habitat. It is assumed that energy performance of urban surrounding is not considered at design stage of architectural project.

    International Nuclear Information System (INIS)

    2003-01-01

    The overall aim of BIOCLIM is to assess the possible long-term impacts due to climate change on the safety of radioactive waste repositories in deep formations. This aim is addressed through the following specific objectives: - Development of practical and innovative strategies for representing sequential climatic changes to the geosphere-biosphere system for existing sites over central Europe, addressing the timescale of one million years, which is relevant to the geological disposal of radioactive waste. - Exploration and evaluation of the potential effects of climate change on the nature of the biosphere systems used to assess the environmental impact. - Dissemination of information on the new methodologies and the results obtained from the project among the international waste management community for use in performance assessments of potential or planned radioactive waste repositories. The BIOCLIM project is designed to advance the state-of-the-art of biosphere modelling for use in Performance Assessments. Therefore, two strategies are developed for representing sequential climatic changes to geosphere-biosphere systems. The hierarchical strategy successively uses a hierarchy of climate models. These models vary from simple 2-D models, which simulate interactions between a few aspects of the Earth system at a rough surface resolution, through General Circulation Model (GCM) and vegetation model, which simulate in great detail the dynamics and physics of the atmosphere, ocean and biosphere, to regional models, which focus on the European regions and sites of interest. Moreover, rule-based and statistical down-scaling procedures are also considered. Comparisons are provided in terms of climate and vegetation cover at the selected times and for the study regions. The integrated strategy consists of using integrated climate models, representing all the physical mechanisms important for long-term continuous climate variations, to simulate the climate evolution over

A partir del impacto de la crisis en curso sobre las Cajas de Ahorro, el Banco de España las sometió a un proceso de intervención, lo que ha llevado a un proceso de concentración y centralización mediante fusiones para fortalecerse y mejorar sus estados contables, y, así, convertirse en entidades bancarias. La bancarización de las 45 Cajas de Ahorro ha sido la alternativa a la crisis financiera y económica en el sistema financiero español.

    The BIOCLIM project on modelling sequential Biosphere systems under Climate change for radioactive waste disposal is part of the EURATOM fifth European framework programme. The project was launched in October 2000 for a three-year period. The project aims at providing a scientific basis and practical methodology for assessing the possible long term impacts on the safety of radioactive waste repositories in deep formations due to climate and environmental change. Five work packages (WP) have been identified to fulfill the project objectives. One of the tasks of BIOCLIM WP3 was to develop a rule-based approach for down-scaling from the MoBidiC model of intermediate complexity in order to provide consistent estimates of monthly temperature and precipitation for the specific regions of interest to BIOCLIM (Central Spain, Central England and Northeast France, together with Germany and the Czech Republic). A statistical down-scaling methodology has been developed by Philippe Marbaix of CEA/LSCE for use with the second climate model of intermediate complexity used in BIOCLIM - CLIMBER-GREMLINS. The rule-based methodology assigns climate states or classes to a point on the time continuum of a region according to a combination of simple threshold values which can be determined from the coarse scale climate model. Once climate states or classes have been defined, monthly temperature and precipitation climatologies are constructed using analogue stations identified from a data base of present-day climate observations. The most appropriate climate classification for BIOCLIM purposes is the Koeppen/Trewartha scheme. This scheme has the advantage of being empirical, but only requires monthly averages of temperature and precipitation as input variables. Section 2 of this deliverable (D8a) outline how each of the eight methodological steps have been undertaken for each of the three main BIOCLIM study regions (Central England, Northeast France and Central Spain) using Mo

  8. Bioclim Deliverable D7: continuous climate evolution scenarios over western Europe (1000 km scale)

    International Nuclear Information System (INIS)

    2003-01-01

    The overall aim of BIOCLIM is to assess the possible long term impacts due to climate change on the safety of radioactive waste repositories in deep formations. This aim is addressed through the following specific objectives: - Development of practical and innovative strategies for representing sequential climatic changes to the geosphere-biosphere system for existing sites over central Europe, addressing the timescale of one million years, which is relevant to the geological disposal of radioactive waste. - Exploration and evaluation of the potential effects of climate change on the nature of the biosphere systems used to assess the environmental impact. - Dissemination of information on the new methodologies and the results obtained from the project among the international waste management community for use in performance assessments of potential or planned radioactive waste repositories. A key point of the project is therefore to develop strategies for representing sequential long-term climatic changes by addressing time scales of relevance to geological disposal of solid radioactive wastes. The integrated strategy, which first step is described in this deliverable (D7), consists of building an integrated, dynamic climate model, to represent all the known important mechanisms for long term climatic variations. The time-dependent results will then be interpreted in terms of regional climate using rule-based and statistical down-scaling approaches. Therefore, the continuous simulation of the climate evolution of the next 200 000 years selected for study is a major objective of the BIOCLIM project. This requires models that account for the simultaneous evolution of the atmosphere, biosphere, land-ice and the ocean. To be able to perform several 200 000-yearlong transient climate simulations, the models have to include all these components, but also need to be simple enough to run fast. Therefore, climate models of intermediate complexity have been chosen to

    The BIOCLIM project (Modelling Sequential Biosphere systems under Climate change for Radioactive Waste Disposal) is part of the EURATOM fifth European framework programme. The project was launched in October 2000 for a three-year period. It is coordinated by ANDRA, the French national radioactive waste management agency. The project brings together a number of European radioactive waste management organisations that have national responsibilities for the safe disposal of radioactive wastes, and several highly experienced climate research teams. Waste management organisations involved are: NIREX (UK), GRS (Germany), ENRESA (Spain), NRI (Czech Republic) and ANDRA (France). Climate research teams involved are: LSCE (CEA/CNRS, France), CIEMAT (Spain), UPMETSIMM (Spain), UCL/ASTR (Belgium) and CRU (UEA, UK). The Environmental Agency for England and Wales provides a regulatory perspective. The consulting company Enviros Consulting (UK) assists ANDRA by contributing to both the administrative and scientific aspects of the project. This paper describes the project and progress to date.

    Bioclimates are syntheses of climatic variables into biologically relevant categories that facilitate comparative studies of biotic responses to climate conditions. Isobioclimates, unique combinations of bioclimatic indices (continentality, ombrotype, and thermotype), were constructed for northern California coastal ranges based on the Rivas-Martinez worldwide bioclimatic classification system for the end of the 20th century climatology (1971–2000) and end of the 21st century climatology (2070–2099) using two models, Geophysical Fluid Dynamics Laboratory (GFDL) model and the Parallel Climate Model (PCM), under the medium-high A2 emission scenario. The digitally mapped results were used to 1) assess the relative redistribution of isobioclimates and their magnitude of change, 2) quantify the loss of isobioclimates into the future, 3) identify and locate novel isobioclimates projected to appear, and 4) explore compositional change in vegetation types among analog isobioclimate patches. This study used downscaled climate variables to map the isobioclimates at a fine spatial resolution −270 m grid cells. Common to both models of future climate was a large change in thermotype. Changes in ombrotype differed among the two models. The end of 20th century climatology has 83 isobioclimates covering the 63,000 km2 study area. In both future projections 51 of those isobioclimates disappear over 40,000 km2. The ordination of vegetation-bioclimate relationships shows very strong correlation of Rivas-Martinez indices with vegetation distribution and composition. Comparisons of vegetation composition among analog patches suggest that vegetation change will be a local rearrangement of species already in place rather than one requiring long distance dispersal. The digitally mapped results facilitate comparison with other Mediterranean regions. Major remaining challenges include predicting vegetation composition of novel isobioclimates and developing metrics to compare

    Full Text Available El siguiente artículo aborda el problema del financiamiento de la inversión para un país en desarrollo, específicamente de la América Latina, tratando de revisar la literatura disponible para llegar a conclusiones sobre cómo los determinantes del ahorro en todas sus versiones -ahorro externo, ahorro privado y ahorro público- ejercen influencia sobre el proceso de crecimiento. Aun cuando la dirección causal exacta entre ahorro y crecimiento no ha sido establecida, el desarrollo de políticas económicas que estimulen el ahorro interno por encima del procedente del exterior, fortalecerían la capacidad de inversión interna y, al existir una correlación positiva entre estas variables, se potencia el proceso de crecimiento aunque otras variables igualmente pueden difuminar tal efecto. Se concluye que el incremento de la relación Ahorro Interno / P. I. B. sólo puede alcanzarse a través de esfuerzos comunes entre empresas, gobierno y el sistema financiero de estas economías.

    The domestic sector consumes almost one quarter of the national electrical energy. In order to reduce in an important manner the power consumption in dwellings there is an integral alternative based on three elements: the bio-climatic design, the saving and efficient use of the energy in equipment and apparatuses, and the use of centralized air conditioning systems. Besides saving the electrical and thermal power consumption, with this scheme, comfort conditions are pretended to be reached in dwellings and, contributing at the same time, to the diminution of polluting emissions. [Spanish] El sector domestico consume casi una cuarta parte de la energia electrica nacional. Con objeto de reducir de manera importante el consumo de energia en las viviendas, se presenta una alternativa integral, basada en tres elementos: el diseno bioclimatico, el ahorro y uso eficiente de la energia en equipos y aparatos, y la utilizacion de sistemas de climatizacion centralizados. Ademas del ahorro en el consumo de energia electrica y termica, con este esquema se pretende alcanzar condiciones de confort en las viviendas y, al mismo tiempo, contribuir a la disminucion de emisiones contaminantes.

  18. A first approach to calculate BIOCLIM variables and climate zones for Antarctica

    2018-02-01

    For testing the hypothesis that macroclimatological factors determine the occurrence, biodiversity, and species specificity of both symbiotic partners of Antarctic lecideoid lichens, we present a first approach for the computation of the full set of 19 BIOCLIM variables, as available at http://www.worldclim.org/ for all regions of the world with exception of Antarctica. Annual mean temperature (Bio 1) and annual precipitation (Bio 12) were chosen to define climate zones of the Antarctic continent and adjacent islands as required for ecological niche modeling (ENM). The zones are based on data for the years 2009-2015 which was obtained from the Antarctic Mesoscale Prediction System (AMPS) database of the Ohio State University. For both temperature and precipitation, two separate zonings were specified; temperature values were divided into 12 zones (named 1 to 12) and precipitation values into five (named A to E). By combining these two partitions, we defined climate zonings where each geographical point can be uniquely assigned to exactly one zone, which allows an immediate explicit interpretation. The soundness of the newly calculated climate zones was tested by comparison with already published data, which used only three zones defined on climate information from the literature. The newly defined climate zones result in a more precise assignment of species distribution to the single habitats. This study provides the basis for a more detailed continental-wide ENM using a comprehensive dataset of lichen specimens which are located within 21 different climate regions.

    Since one of the restrictive problems when investing in energy saving is the uncertainty of obtaining the planed savings, a technique in the risk handling for energy efficiency projects, called Insurance for the Energy Saving (IES) is presented. IES economically stimulates those who implement projects for energy saving so they go beyond the normal measures and really obtain significant saving levels, thus contributing to the fulfillment of national objectives in energy saving. In order to reduce the risk of low performance in energy caused by saving projects there exist the international performance measurement and the protocol of investment (IMPVP) as well as diagnoses and starting processes, whereas in order to transfer the financial risk that a saving project represents, mechanisms such as FDIC insurance, conversion of the debt in values, Saving's Guarantees, Performance Bonuses or Guarantee Bonuses and Insurances for Energy Saving can be of great help. This article deals on the IES insurance policies, their loss control management, successful cases, benefits, particular advantages, place in the market and refers argued insurance exceptions and perception surveys.

    2002-01-01

    Marianne Calvez (ANDRA, France) presented the new EC BIOCLIM project that started in 2001. Its main objective is to provide a scientific basis and practical methodology for assessing the possible long-term impacts on the safety of radioactive waste repositories in deep formations due to climate driven changes. She explained that BIOCLIM objective is not to predict what will be the future but will correspond to an illustration of how people could use the knowledge. The BIOCLIM project will use the outcomes from the Biomass project. Where Biomass considered discrete biospheres, the BIOCLIM project will consider the evolution of climate with a focus on the European climate for three regions in the United Kingdom, France and Spain. The consortium of BIOCLIM participants consists of various experts in climate modelling and various experts and organisations in performance assessment. The intent is to build an integrated dynamic climate model that represents all the important mechanisms for long-term climate evolution. The modelling will primarily address the next 200000 years. The final outcome will be an enhancement of the state-of-the-art treatment of biosphere system change over long periods of time through the use of a number of innovative climate modelling approaches and the application of the climate model outputs in performance assessments

    The traditional sugar mill is inefficient from the energy point of view. Most of the sugar mills were designed to use all the available bagasse, due to the risk of spontaneous ignition and environmental pollution. Consequently, the steam generators, the turbines and other components were designed to work with low efficiencies. Each ton of sugar produced generates a power potential equivalent to four to six oil barrels (bagasse and residues). That is to say, a sugar mill is capable of producing 500 ton/day of sugar, equivalent to an oil well of 2000 to 3000 barrels/day and one thermoelectric power plant of 15,000 kW. Under this context an analysis is made of the sugar mills in Latin America and the Caribbean as one of the ways of increasing their efficiency and obtain great energy savings. As far as steam generation the appropriate use of energy is dictated by the boilers' efficiency. [Spanish] El ingenio azucarero tradicional es ineficiente desde el punto de vista energetico. La mayoria de los ingenios azucareros se disenaron para usar todo el bagazo disponible, debido al riesgo de ignicion espontanea y contaminacion. En consecuencia, los generadores de vapor, las turbinas y demas componentes fueron disenados para trabajar con bajas eficiencias. Cada tonelada de azucar producida genera una potencialidad energetica equivalente de cuatro a seis barriles de petroleo (bagazo y residuos). Es decir, un ingenio capaz de producir 500 ton/dia de azucar equivalente a un pozo de petroleo de 2000 a 3000 barriles/dia y una termoelectrica de 15000 kW. Bajo este contexto se hace un analisis del ingenio azucarero en Latinoamerica y el Caribe como una de las vias para incrementar su eficiencia y lograr grandes ahorros en la energia. En cuanto a generacion de vapor se refiere, el buen uso de la energia viene expresado por la eficiencia de las calderas.

    The design and construction of current buildings has been characterized, most of all, in the last 30 years, for the lack of consideration in the design process of aspects that nowadays represent a fundamental importance. These aspects are related to energy conservation and environmental protection, with man as the main center of attention for the optimum satisfaction of its physiological as well as psychological needs. In this paper are presented the causes for the lack of consideration of the mentioned aspects and guidelines to follow are set forth for their integration in the design process. Also the architecture potential with a bioclimatic approach is analyzed, for energy saving in buildings.

    For Plant CIVAC of Nissan Mexicana, the energy saving began in the year of 1990. From then, different programs have been developed using different strategies for energy saving until arriving at the Benchmarking with other Plants of Japan, which represents a new challenge, since it opened up an area of opportunity of saving in processes that generally were known in detail as far as to its main function (to make vehicles with quality, cost and opportunity of delivery), but the parameter of energy consumption of by unit and its benefits in relation to the cost was unknown. This was endorsed by the high Direction and began with the optimization of training for the operation of each equipment with the involvement of the user (Production), the engineering area (that establishes the process) and the maintenance area. We designed a general program where the basic activities were included, such as the general and special activities. Each one of them fulfilled its objective, but the special activities took us to the optimization of the processes, finding excess of energy in the design conditions.

    The present work looks for integrating the actions of energy saving that can be applied in educative institutions, not concerning the level or size of the same ones. The actions go from questions of making aware the student population until those involved in the change in the operation, migration and implementation of technology. Without overlooking the formative aspect that the educative institutions have and the social commitment of these last ones. It is important that the saving measures have as mission to achieve a culture focussed to make efficient use of the resources, of energy as well as material. This culture must be born from the classrooms and must transform the way to be and act of the student community that will permeate itself with the society. Let us remember that actions are worth more than words, so the educative institutions must preach with the example. [Spanish] El presente trabajo busca integrar las acciones de ahorro de energia que pueden ser aplicadas en instituciones educativas, no importando el nivel o tamano de las mismas. Las acciones van desde cuestiones de concienciar a la poblacion estudiantil hasta las que involucran el cambio en la operacion, migracion e implementacion de tecnologia. Sin perder de vista el aspecto formativo que tienen las instituciones educativas y el compromiso social de estas ultimas. Es importante que las medidas de ahorro tengan como mision lograr una cultura enfocada a hacer uso eficiente de los recursos, tanto energeticos como materiales. Dicha cultura debe nacer desde las aulas y debe transformar la manera de ser y actuar, de la comunidad estudiantil que se permeara con la sociedad. Recordemos que las acciones valen mas que las palabras, asi que las instituciones educativas deben predicar con el ejemplo.

The data and information collated in this report for three of these countries (France, Spain and the United Kingdom) will be used within BIOCLIM to guide the development of down-scaling rules for regional climate characteristics and thereby to provide a basis for linking climate model output to system descriptions required for the purposes long-term safety assessment. In each case, the description begins with a summary of the present-day characteristics of the regions/sites of interest, categorized under the following headings: site location and the geology of the region; human communities and land use; topography; climate; litho-stratigraphy; surface water bodies; and biota These site descriptions are then followed by a detailed presentation of the information base that has enabled palaeo-reconstructions of environmental change to be made within each country. The intention is that, by correlating these reconstructions with the global climate record, it will be possible to develop down-scaling procedures that allow the projected effects of future global climate change to be reflected in assumptions about biosphere conditions relevant to long-term radiological safety assessments. Key outputs from the palaeo-environmental analysis for each selected region include: - a narrative description of the sequence of climate change at a regional scale, expressed in terms of simple climate parameters, such as the estimated mean annual temperature, associated with defined time periods. - associated descriptions of environmental change, taking into account the effects on hydrology, soils and vegetation. - identification of key environmental properties associated with a range of 'typical' conditions that have prevailed in different regions of Europe during the last glacial-interglacial cycle. Additional information for the Czech Republic has also been summarised for interest and comparison. Because the information described

    International Nuclear Information System (INIS)

    2001-01-01

    The BIOCLIM project aims at assessing the possible long-term impacts of climate change on the safety of waste repositories in deep formations using climate simulations of the long-term climate in various European areas. One of the objectives of the project is to develop two strategies for representing sequential climatic changes to the geosphere-biosphere system for different sites over Europe, addressing the time scale of one million years. The results of this work will be interpreted in terms of global or regional changes of climate and of vegetation. The first strategy (hierarchical strategy) will use the full hierarchy of existing climate models (a climate model is a numerical simplified representation of the climate system behaviour and evolution). Simple models (LLN 2-D NH and threshold models; see the description here after) will simulate the overall long-term evolution of the global climate. Their results will then be used as inputs to more complex models (LMD climate models possibly coupled with vegetation models, either SECHIBA or ORCHIDE) and finally climate and vegetation cover will be determined for specific sites at specific times. A second strategy (integrated strategy) will consist in building an integrated climate model, which represents most of the physical mechanisms for studying long-term climatic variations. The results will then be interpreted on a regional scale. This deliverable is the first step of the hierarchical strategy. The purpose of this deliverable is to identify and justify some specific climatic situations amongst different long-term simulations that are of interest for assessing the safety of radioactive waste repository sites and that will be further studied with GCMs (General Circulation Model). The simple threshold (or multi-state) climate model is a modified version of the model from Paillard. It describes the time evolution of the ice volume and the CO 2 concentration. It has two distinct regimes (interglacial and glacial

    Full Text Available El objetivo de este artículo es realizar un diagnostico del potencial productivo del ahorro migrante para el caso del estado de Michoacán. Los datos obtenidos muestran un perfil de Michoacano radicado en EUA con ingresos suficientes para enviar remesas familiares a México pero limitados para realizar inversiones mayores a 200 dólares mensuales en Michoacán. Dentro de esa limitación, de contar con capital, los michoacanos manifestaron una preferencia por invertir en México y específicamente en su comunidad de origen. La preferencia de inversión mas citada es la compra de una vivienda o reparación de la misma. Asimismo, la corrupción y la inseguridad son señaladas como obstáculos para la inversión en México. Finalmente, el alto porcentaje de migrantes indocumentados encontrados en la encuesta refleja los profundos impactos que una reforma migratoria en EUA puede tener en la dinámica económica del estado. La migración a EUA puede dejar de convertirse en la válvula de escape para la población michoacana que no encuentre oportunidades laborales en Michoacán sumiendo a la entidad en graves problemas económicos y sociales.

    The enormous electric energy consumption in buildings represents an important area of saving opportunities. The design of installations without advanced technical illumination criteria, the absence of standardization over energy efficiency, the lack of observation of the existing standards and guides, the continuous load growth in existing installations and the lack of appropriate maintenance, are some of the causes of the inefficient use of electric energy in buildings. Although the problems, and consequently the solutions, are exclusive for each unit, some of the former are frequently repeated. In this paper the problems found along more than 40 audits conducted in large buildings of different types in Mexico city are commented. [Espanol] El enorme consumo de energia electrica en edificios representa una importante area de oportunidad para ahorro. El diseno de instalaciones sin criterios luminotecnicos avanzados, la ausencia de normalizacion sobre eficiencia energetica, la falta de observancia de las normas y recomendaciones vigentes, el continuo crecimiento de carga en instalaciones existentes y la falta de mantenimiento adecuado son algunas de las causas del uso ineficiente de la energia electrica en inmuebles. Aunque los problemas y por tanto las soluciones son particulares para cada unidad, algunos de los primeros se repiten frecuentemente. En este trabajo se comentan los problemas encontrados a lo largo de mas de 40 auditorias realizadas a inmuebles grandes de diversos tipos en la ciudad de Mexico.

  20. Bioclim Deliverable D10 - 12: development and application of a methodology for taking climate-driven environmental change into account in performance assessments

    International Nuclear Information System (INIS)

    2004-01-01

    The BIOCLIM project on modelling sequential Biosphere systems under Climate change for radioactive waste disposal is part of the EURATOM fifth European framework programme. The project was launched in October 2000 for a three-year period. The project aims at providing a scientific basis and practical methodology for assessing the possible long term impacts on the safety of radioactive waste repositories in deep formations due to climate and environmental change. Five work packages have been identified to fulfill the project objectives: - Work package 1 will consolidate the needs of the European agencies of the consortium and summarize how environmental change has been treated to date in performance assessments. - Work packages 2 and 3 will develop two innovative and complementary strategies for representing time series of long term climate change using different methods to analyse extreme climate conditions (the hierarchical strategy) and a continuous climate simulation over more than the next glacial-interglacial cycle (the integrated strategy). - Work package 4 will explore and evaluate the potential effects of climate change on the nature of the biosphere systems. - Work package 5 will disseminate information on the results obtained from the three year project among the international community for further use. The output from the climate models developed and applied in WP2 and WP3 has been interpreted in WP4 ('Biosphere system description') in terms of model requirements for the post-closure radiological performance assessment of deep geological repositories for radioactive wastes, in order to develop a methodology to demonstrate how biosphere systems can be represented in the long-term. The work undertaken in WP4 is described in this report. This report describes the methodology used for identification and characterisation of specific climate states and transitions between those climate states. It also covers the application of those methods in the context of

    Full Text Available Frente al excesivo consumo energético en el acondicionamiento térmico residencial, este estudio investiga la implicancia del clima local en las estrategias de expansión urbana, así como su grado de afección a las condiciones de confort, en el contexto mediterráneo español de la Costa del Sol Occidental. Para ello se realiza un análisis bioclimático territorial, identificando los diversos climas locales existentes y las diferentes respuestas biológicas asociadas a cada uno de ellos. Con estos resultados se elabora una clasificación del lugar desde la óptica de la idoneidad bioclimática. Esta herramienta ha permitido evaluar los procesos de planificación territorial, concluyéndose que el 80,6% del suelo urbano y urbanizable no se beneficia de las condiciones climáticas más favorables, las cuales constituyen el 47,3% del territorio analizado. Esta información, puesta al servicio de mejorar las condiciones térmicas de las ciudades, puede ser útil en el diseño y distribución de futuras áreas urbanas.

    This paper presents some of the fundamental issues related to energy conservation programs in general and to the petroleum industry in particular with the purpose of integrating them both, that is, considering not only the energy issues, but also the ecological and economical aspects. This is achieved by using the two fundamental laws of thermodynamics (the science that studies energy, its characteristics, and its transformations) through the use of the exergy concept, which is a measure of the energy quality and of its withdrawal with respect to the environment. The origins of the present-day technologies, regarding energy conservation, the short, medium and long term general strategies and the implementation stages of the integral programs of energy conservation are presented, and it concludes with a series of general policies aimed at making the energy conservation programs more congruent with the maintenance of a sustainable development.

Se ha planteado un estudio de caso en el que luminarias de halogenuros metálicos han sido sustituidas por luminarias LED. Para validar la sustitución de luminarias con halogenuros metálicos de 400W por LED de 200W, se han efectuado las simulaciones luminotécnicas y mediciones de campo mediante luxómetro. Los resultados obtenidos indican que ambas luminarias son equiparables obteniendo un importante ahorro energético cercano al 50%. Esta investigación demuestra que la tecnología LED ofrece soluciones de iluminación de alto rendimiento que optimizan el ahorro energético reduciendo a su vez costes de mantenimiento con un coste total de propiedad significativamente menor, incrementando la esperanza de vida útil de las luminarias. Desde el punto de vista medioambiental supone una importante reducción en emisiones de CO2 y eliminación de residuos tóxicos como el mercurio.

    The paper describes the relationship between the urban areas and their environment in a world community aware of the ill-conceived energy ideas of this wasteful century, to an area of efficient and sustainable energy systems. The environmental preoccupation is on every discipline, and this Thesis rethinks about planning, environment and climate. On urban planning the answers are still more theoretical than practical, not only because of the natural complexity of the urban phenomenon, but also because the answers must be very particular to the place and local climate conditions. The study must be very particular to the place and local climate conditions. The study ends with two practical case studies on the Madrilenian Community, on two different climate areas.

    In the present paper the evaluation of the potential of saving of electrical energy in Mexico is presented, by means of the substitution of old refrigerators of low efficiency by modern high efficiency ones. This potential is very ample, since the replacement of the old models by new follows a very slow curve, if the economic difficulties of the Mexican families are considered and that, on the other hand, the technology of the domestic refrigerators is so reliable that they have a very long life and they are not easily rejected. In field work have been found refrigerators operating with ages of more than 30 years and still 40. In Mexico, it is estimated that the refrigeration is responsible for around 29% of the of electricity consumption in homes settled in tempered climate and of 14 % in those of warm climate in which air conditioning is used. The proposal of this work is the organization of a governmental program of accelerated substitution of refrigerators that helps to acquire an efficient refrigerator and to reject the old ones. The results indicate that if a total renovation of the park of domestic refrigerators is made, the saving of electrical energy would reach the 5.2 TWh/a which represents the 44.5% of the total consumption of 11.7 TWh in a year. [Spanish] En el presente trabajo se presenta la evaluacion del potencial de ahorro de energia electrica en Mexico, mediante la substitucion de refrigeradores antiguos de baja eficiencia por modernos de alta eficiencia.

    The Facultad de Ingenieria of the Universidad Autonoma del Estado de Mexico (UAEM), in its postgraduate program in Transport Engineering carries out research projects aimed at the appropriate operation of the urban public transportation, in the definition of the transportation networks and their exploitation as well as in the energy conservation and efficient use of the energy for its operation. This paper embodies the lines of interest of this program. The proper operation characteristics and the energy consumption of the different types of vehicles used in urban public transportation mainly depend on the application they have been designed for. Nevertheless, an important point is to know, in the most concrete and specific form, the nature and other possible utilization options of the different urban transportation systems, as well as its energy impact and the possibility of a well oriented energy conservation. The purpose of this paper is to present in a concrete manner the different types of vehicles used in the urban public transportation, making an energy comparison, besides setting forth a program of actions tending to the energy saving for the vehicles that nowadays operate in the main cities of our country. The main actions are pointed out and the basic characteristics for their initiation, which can be summarized in three large groups: -action in the proper enterprises and with existing vehicular park. -actions over the management and exploitation of the transportation systems. -action for the utilization of new equipment and more efficient vehicles. A detailed explanation of each one of these actions and their impact on the energy consumption are the final purpose of this study.

  5. Bioclim Deliverable D4/5: global climatic characteristics, including vegetation and seasonal cycles over Europe, for snapshots over the next 200,000 years

    International Nuclear Information System (INIS)

    2003-01-01

    The aim of the BIOCLIM project is to develop and present techniques that can be used to develop self-consistent patterns of possible future climate changes over the next million years (climate scenarios), and to demonstrate how these climate scenarios can be used in assessments of the long-term safety of nuclear waste repository sites. Within the project, two strategies are implemented to predict climate change. The first is the hierarchical strategy, in which a hierarchy of climate models is used to investigate the evolution of climate over the period of interest. These models vary from very simple 2-D and threshold models, which simulate interactions between only a few aspects of the earth system, through general circulation models (GCMs) and vegetation models, which simulate in great detail the dynamics and physics of the atmosphere, ocean, and biosphere, to regional models, which focus in particular on the European region and the specific areas of interest. The second strategy is the integrated strategy, in which intermediate complexity climate models are developed, and used to consecutively simulate the development of the earth system over many millennia. Although these models are relatively simple compared to a GCM, they are more advanced than 2D models, and do include physical descriptions of the biosphere, cryo-sphere, atmosphere and ocean. This deliverable, D4/5, focuses on the hierarchical strategy, and in particular the GCM and vegetation model simulation of possible future climates. Deliverable D3 documented the first step in this strategy. The Louvain-la-Neuve 2-D climate model (LLN-2D) was used to estimate (among other variables) annual mean temperatures and ice volume in the Northern Hemisphere over the next 1 million years. It was driven by the calculated evolution of orbital parameters, and plausible scenarios of CO 2 concentration. From the results, 3 future time periods within the next 200,000 years were identified as being extreme, that is

    In Mexico the second most used electrical appliance is: refrigerator. Owing to its use, it would be a promising option for electric power saving. In Guadalajara, Reynosa and Tampico it was performed a study with the aim of launching a project to replace the old refrigerators with new ones which are more effective and less expensive. Since the refrigerators cost and the electrical invoicing saving, the electric appliance change is profitable. To expect with this replacement more than eight million of refrigerators manufactured before 1997 will be changed. [Spanish] El refrigerador es el segundo electrodomestico mas utilizado a nivel nacional, esto permite que debido a su uso sea una opcion prometedora para el ahorro de energia electrica. Se hizo un estudio en Guadalajara, Reynosa y Tampico con el fin de lanzar un proyecto para sustituir los refrigeradores viejos por unos nuevos que sean mas eficaces y menos costosos. Por el costo de los refrigeradores y el ahorro en la facturacion electrica, el cambio de electrodomestico es rentable, de esta manera se espera que los mas de ocho millones de refrigeradores fabricados antes de 1997 que existen en el pais sean cambiados.

    Full Text Available In this work we analyzed the problems derived from the potential species loss associated to the taphonomic processes occurring in fossil sites. We seek to resolve the possible utility of cenograms and bioclimatic analysis as methodologies applicable in Paleoecology. Supposedly, if species are deleted in a community, significant changes in its structure might appear, which would make these paleoecological techniques dysfunctional. The analysis has been carried out with the data of two modern mammalian communities, Barrow (Alaska and Jaipur (India, on which we have deleted species randomly. Our results have allowed us to conclude that these methodologies are useful in Paleoecology, since they are functional with a satisfactory level of confidence, as long as the species loss is not excessively elevated (for communities with 20-40% of the original species.En este trabajo hemos analizado la problemática derivada de la posible pérdida de especies asociada a los procesos tafonómicos que se dan en los yacimientos de fósiles, para determinar la posible utilidad de los cenogramas y el análisis bioclimático como metodologías aplicables en Paleoecología. Podría suponerse que si eliminamos especies en una comunidad se podrían producir cambios significativos en su estructura que convertirían en no funcionales a estas metodologías. El análisis se ha llevado a cabo con los datos de dos comunidades de mamíferos actuales, Barrow (Alaska y Jaipur (India, de las que hemos eliminado progresivamente especies de forma aleatoria. Los resultados obtenidos nos han permitido concluir que tanto los cenogramas como el análisis bioclimático son útiles en Paleoecología, ya que son funcionales con un nivel de confianza adecuado, siempre y cuando la pérdida de especies no sea excesivamente elevada (en comunidades con un 20-40% de las especies originales.

    Full Text Available La oferta de aplicaciones y servicios multimedia para terminales móviles se hace principalmente a través de las redes celulares de tercera y cuarta generación (3G/4G existentes. El envío de los datos en este tipo de redes se realiza en modo unicast, es decir, a cada usuario se le dedican recursos de radio (ancho de banda y potencia de transmisión durante toda la sesión. Esto presenta algunos inconvenientes, tales como agotamiento rápido del ancho de banda del operador móvil, alto consumo de potencia de transmisión, incremento de la interferencia, y costos altos del servicio. Los operadores móviles requieren de nuevas tecnologías que optimicen el uso de sus recursos de radio y así lograr un mayor índice de penetración de los servicios. De ahí la necesidad de cambiar de paradigma hacia un modo de transmisión en multicast o broadcast, en el que una misma señal pueda recibirse por varios usuarios simultáneamente, de tal forma que los recursos de radio se puedan compartir. Para ello, la solución técnica sobre redes celulares LTE (Long Term Evolution se dio en la especificación 3GPP Release 6, llamada Servicio Multimedia por Broadcast/Multicast (MBMS, Multimedia Broadcast Multicast Service. La especificación de MBMS permite que una transmisión cambie de modo unicast a modo multicast a partir de un “punto de conmutación”, que determina el momento de hacer el cambio para obtener un ahorro tanto en ancho de banda como en potencia de transmisión. Este artículo presenta una evaluación para determinar los puntos de conmutación de modo de transmisión óptimos en el estándar MBMS para diferentes ambientes de propagación inalámbrica. Además, dado que MBMS se puede utilizar en topologías de Red de Frecuencia Única (SFN, Single Frequency Networks, que tienen la propiedad de “ganancia de red”, también se determina el ahorro de potencia de transmisión adicional que se obtiene en esta configuración.

    Full Text Available Objetivos: Estimar el ahorro potencial que podría tener lugar en el Servicio Canario de Salud (SCS, a partir de una utilización apropiada científica de las pruebas preoperatorias, haciendo uso de la información obtenida de los 5 hospitales universitarios de la red pública. Métodos: Un total de 55 anestesiólogos (60% del SCS cumplimentaron un cuestionario. En éste se prestó especial atención a las pruebas preoperatorias más frecuentemente utilizadas, como la radiografía de tórax, el electrocardiograma, las pruebas de laboratorio y la espirometría. Los costes unitarios medios para las diferentes pruebas preoperatorias se obtuvieron de 2 hospitales participantes en el estudio. Para calcular los ahorros potenciales derivados del uso apropiado de las pruebas preoperatorias se han considerado varios escenarios caracterizados por diferentes hipótesis o grados de cumplimiento de un protocolo basado en el conocimiento científico, considerado como parámetro de referencia. Resultados: En el caso ideal de que se cumpliera el protocolo científico recomendado en el 100% de los 16.179 pacientes considerados ASA I y II, la repercusión económica sería notable, pues supondría una liberación de recursos sensible que podría ser utilizada para otros programas de salud. Estas cifras podrían alcanzar aproximadamente los 1,02 millones de euros, sin considerar el coste de la estancia preoperatoria. Esta cifra podría incrementarse hasta, aproximadamente, los 2,13 millones de euros si incluimos un día de estancia preoperatoria, y hasta los 3,24 millones de euros incluyendo 2 días de estancia preoperatoria. Conclusiones: La revisión reciente de la literatura científica y los resultados proporcionados por el cuestionario aplicado en el SCS indican que las pruebas preoperatorias alcanzan los mayores beneficios para los pacientes y para la sociedad si se guían por el conocimiento científico.

    Every one involved with the conservation and efficient use of electric energy, has listened in reiterative occasions to the causes that changed the conventional mentality at the beginning of the seventies. Nevertheless, there are many persons that still ignore that by using the energy rationally, their costs are significantly reduced, their comfort is enhanced and the environmental problems are minimized. Specifically, in the domestic sector, from the figures reported by the Comision Federal de Electricidad (CFE) in 1996, the electric energy sold was 28,410 Gwh, that is, 23.4% of the total consumption (121,579 Gwh). Table 1 presents the average by tariff in the national domestic sector, which shows that 20% of the electricity consumed was required for environmental conditioning (air conditioning, evaporative coolers and electric fans). The above figures quantitatively show that there is a strong impact in the consumption of electric energy due to weather conditions. For this reason, currently the Comision Nacional de Ahorro de Energia (CONAE) and the Fideicomiso para el Ahorro de Energia (FIDE) are promoting standards and projects to propitiate the rationalization in the use of energy, besides of achieving the improvement of thermal comfort conditions. One more case would be the Fideicomiso para el Aislamiento Termico de la Vivienda en Mexicali (FIPATERM), which promotes the financing of saving measures and efficient energy use in cities with extreme climate. This paper describes the strategy that was followed by the Instituto de Investigaciones Electricas (IIE), for the development of the human and material infrastructure, that has allowed the sustainment of several projects in the saving and efficient use of energy in CFE, CONAE, FIDE, FIPATERM and the Lawrence Berkeley National Laboratory (LBNL), concretely in relationship with the thermal analysis of dwellings.

    In this article the evaluation of the solar heat gains through the transparent parts of a building (houses of social interest) is presented; with the purpose of determining the heat gains through windows during summer time and under the following conditions: without solar protection, with the use of eaves, solar breakers and, finally, with the use of both elements. With the determined percentage of the diminution of heat gains, the considered potential of energy saving in air conditioning was obtained that would be available if the houses were constructed with solar control. [Spanish] En este articulo se presenta la evaluacion de las ganancias de calor solar a traves de las partes transparentes de un edificio (viviendas de interes social); con el objeto de determinar las ganancias de calor a traves de ventanas para la epoca de verano y bajo las siguientes condiciones: sin proteccion solar, con el empleo de aleros, con quiebrasoles y, finalmente, con el empleo de ambos elementos. Con el porcentaje determinado de la disminucion de ganancias de calor, se obtuvo el potencial estimado de ahorro de energia en aire acondicionado que se tendria si las viviendas se construyen con control solar.

    termico generado al interior de las edificaciones por las inadecuadas propiedades de los materiales de construccion, se desarrollaron en este trabajo filtros solares con base en hierro por medio de los cuales se logra un control selectivo de la radiacion solar que se transmite a traves de las ventanas. Estos filtros solares consisten en peliculas delgadas de FeO depositadas sobre sustratos de vidrio cal-sosa (el mas usado en nuestro pais para las edificaciones) de 600x300x3 mm, por medio de la tecnica de sputtering asistida con radiofrecuencia y magnetrones planos, partiendo de un blanco de hierro puro de 127x254 mm y usando un plasma de argon. Para obtener el grado de oxidacion deseado en el hierro, pequenas muestras (45 x 22 mm) fueron sometidas a un proceso de calentamiento en una atmosfera reductora constituida de 50% H{sub 2} + 50% N{sub 2}, durante un periodo de tiempo de 10 minutos a una temperatura de 400 C. Los filtros solares con base en FeO presentan una transmisividad de 30.2% para el intervalo visible del espectro electromagnetico (radiacion con longitud de onda de 380-780 nm), y de 39.9% para el infrarrojo cercano (radiacion con longitud de onda de 780-2500 nm); mientras que su reflectividad es de 17.5 y 19%, para los intervalos visibles e infrarrojo cercano del espectro electromagnetico respectivamente. Se realizo una simulacion, a traves del software Energy 10, del comportamiento energetico de una casa-habitacion cuando utilizan en las ventanas vidrios simples (una lamina) tipo cal-sosa, asi como tambien cuando esta misma edificacion usa en las ventanas los filtros solares con base en FeO desarrollados. Ambos casos se comparan obteniendose asi los posibles ahorros de energia por el uso de dichos filtros solares en las ventanas. Las simulaciones fueron llevadas a cabo para diferentes localidades del pais, obteniendose que los filtros solares con base en FeO desarrollados, permiten ahorros de energia principalmente por concepto de acondicionamiento de aire

    Full Text Available El presente trabajo estudia el comportamiento térmico y energético de edificios residenciales en altura, en el contexto particular de una “ciudad-oasis”. Se plantea como objetivo la definición de sistemas de control solar adecuados en la envolvente para cada tipología material de edificio -másica y liviana- y para cada estrato en altura de las viviendas: debajo y sobre de la copa de los árboles. El monitoreo de viviendas en uso permite validar modelos geométricos (software Energy Plus y simular propuestas de aplicación de elementos de protección solar. Se analizan los ahorros en los consumos para enfriamiento en departamentos en niveles bajos, medios y altos. Los resultados muestran que en el edificio másico, en las viviendas ubicadas debajo de la copa de los árboles, es posible anular las cargas energéticas para enfriamiento mediante el uso de elementos exteriores de protección solar. Mientras que en las viviendas sobre la copa de los árboles, los ahorros energéticos se encuentran entre el 32% y 42%. En el edificio liviano, la aplicación de sistemas de control en departamentos bajo la copa de los árboles alcanza ahorros del orden del 53% y en las viviendas sobre la copa, las reducciones energéticas se encuentran entre el 46% y 54%. Las dimensiones adecuadas de tales elementos pueden generar propuestas posibles de ser transferidas a las normativas locales de edificación.

So that these actions were applied in an easy and opportune form, it was established that within the structure of the General Coordination of Foreign Municipalities, the Program of Energy Saving depended directly of the Technical Management of CFE. In this way, the recommendations are first put under consideration of high-level officers, and then are lowered to the operative departments. [Spanish] Para el logro de los objetivos se acordo utilizar, entre otras, las siguientes estrategias: capacitacion del personal; aumentar la eficiencia de los equipos electromecanicos; estudio de tarifas de la Comision Federal de Electricidad (CFE); correccion de bajos factores de potencia; aumento de los factores de carga; automatizar la operacion; regular de los tiempos de operacion; mantenimiento preventivo a los equipos; establecimiento de normas tecnicas; uso racional y eficiente de aire acondicionado e iluminacion. Para que estas acciones se aplicaran en forma agil y oportuna, se establecio que dentro de la estructura de la Coordinacion General de Municipios Foraneos, el Programa de Ahorro de Energia dependiera directamente de la Gerencia Tecnica de la CRE. De esta forma, las recomendaciones primero se someten a consideracion de los funcionarios de alto nivel, y luego bajan a los departamentos operativos.

    The motor-compressors are a key part of the industrial processes. The reliability and efficient operation of a compressor is critical. The surge phenomenon is a threat in the reliability of a compressor and therefore for the process. Surge, in a centrifugal compressor is defined as a dramatic flow and pressure drop, including back-flow. This is always a significant process disturbance. Continuous surge results into costly process shutdowns and mechanical damages. To prevent surge, and control the discharge pressure with simple or obsolete controls it is needed to vent air to the surrounding atmosphere. This form of control is very inefficient and costly. An advanced control with leading technology, besides providing an economical value preventing surge damages, offers substantial energy saving reducing or eliminating the venting of air to the atmosphere. [Espanol] Los motocompresores son un aparte clave de los procesos industriales. La confiable y eficiente operacion de un compresor es critica. El fenomeno de surge es una amenaza a la confiabilidad de un compresor y por lo tanto del proceso. El surge en un compresor centrifugo es definido como una dramatica caida de flujo y presion, incluyendo flujo inverso. Esto es siempre un significante disturbio del proceso. El surge continuo resulta en costosos paros de proceso y danos mecanicos. Para prevenir el surge y controlar la presion de descarga con controles simples u obsoletos, es necesario ventear aire a la atmosfera. Esta forma de control es muy ineficiente y costosa. Un control avanzado con tecnologia de punta ademas de proveer valor economico previniendo danos por surge, provee sustanciales ahorros de energia reduciendo o eliminando el venteo de aire a la atmosfera.

    In Michoacan, Mexico, a project who seeks to benefice the Municipal public resources was crated in 1994. It would be achieved trough the electric power saving in the public lighting system, and drinkable water pumping and black water, since those activities required the budget biggest part. The program could be developed recently and the saving was significant. In addition the electromechanical efficiency increased in the equipment installation. This work is an example for other States to do something similar that can improve their conditions. [Spanish] En el estado de Michoacan, Mexico se creo un proyecto en el ano de 1994, el cual buscaba beneficiar los recursos publicos municipales, a traves del ahorro de la energia electrica en los sistemas de alumbrado publico y bombeo de agua potable y aguas negras, ya que estas actividades son las que requieren la mayor parte del presupuesto. El programa pudo llevarse a cabo en anos recientes y el ahorro fue significativo, ademas de que aumento la eficiencia electromecanica en los equipos que se instalaron, y esta obra ha servido de ejemplo a otros estados para que realicen algo similar que pueda mejorar su situacion.

    In a lighting system the discharge lamps (fluorescent and high intensity discharge (HID)), ballast and controls are generating elements of harmonics. As a consequence of the tendency of saving energy, the use of electronic ballasts and controls that integrate dimmers, daylight and present sensors has increased in order to optimize the energy use. This paper presents the harmonics generation resulting from the fluorescent lamps operating different electronic ballasts as well as their electronic controls. Likewise, are also shown the effects caused by generation of harmonics components by the lighting system in the electric system that go from the voltage and current distortion, the presence of currents in the neutral conductor in balanced systems to the repercussions in the metering equipment such as watthour meters and the effects the lighting equipment suffer due to the presence of harmonics, such as the power factor decrease in ballasts that are of high power factor and the temperature increment in the magnetic type ballasts.

    Full Text Available Las reformas legislativas que han afectado en los últimos tiempos a la organización y el funcionamiento del sistema financiero español han tenido una especial repercusión en el ámbito de las cajas de ahorros. La tramitación parlamentaria de la Ley 44/2002, de 22 de noviembre, de Medidas de Reforma del Sistema Fianciero, reavivó el debate sobre su régimen jurídico y la necesidad de acotar la intervención pública en su seno. Ahonda en ello la Ley 26/2003 , de 17 de julio, de Transparencia, que extiende al ámbito de las cajas la preocupación por el corporate governance. Ambas normas responden a la necesidad de dar respuesta a algunos de los problemas más inmediatos a que se enfrentan estas entidades, si bien adolecen de un defecto fundamental por cuanto no abordan de forma exhaustiva la regulación de la institución. Se perpetúa así la trayectoria tradicional de "parcheo" del régimen jurídico aplicable a las mismas, evitando entrar en la cuestión esencial de la definición de su naturaleza jurídica y abocando a las cajas, en consecuencia, al díficil reto de acompasar su vocación social tradicional a las nuevas exigencias legales en pro de una mayor eficiencia, racionalidad y neutralidad de su acitividad económica.Recent legal changes pertaining to the organization and performance of the Spanish financial system have had significant repercussions on the savings banks sector. The law on financial market reform passed in 2002, Ley Financiera, raised once again the debate on their legal situation and the urge to cut down public influence on their management. The 2003 Transparency Law, Ley de Transparencia, follows this reform and extends corporate governance to Spanish savings banks. Both Laws seek to confront some of the most important issues raised by these credit institutions, but they also share the flaw of not regulating its legal framework and status completely. They continue, therefore, to add "patches" to the savings

    This paper presents a diagnosis of the electrical energy consumption in the library of the Azcapotzalco Unit of the Universidad Autonoma Metropolitana, to determine the actions that can be implemented for energy conservation. This without disturbing the lighting and thermal comfort. The analysis showed that, by changing the reflecting surfaces of the lighting lamps, the number of units can be reduced, without lowering the illumination level below the recommended values. The saving was estimated for replacement of the fluorescent lamps for others of metallic halogenides in the areas where the ceiling is high; for the installation of switches to improve the selectivity in turning on and turning off the lamps, achieving this way a better usage of the natural light; for the reduction of the electric load of the air conditioning units which will be obtained in incorporating induced draft shafts; and for an improvement in the electric and ballast installation. For the actions that turned out to be redeemable in three years the assistance of the Fideicomiso de Apoyo al Programa de Ahorro de Energia del Sector Electrico (FIDE) of the Comision Federal de Electricidad (CFE) has been available. It is expected that the execution of the modifications will be carried out in the November and December months of 1993, and the results will be evaluated in 1994.

    Full Text Available El aprovechamiento del agua lluvia es una práctica interesante, tanto ambiental como económicamente, si se tiene en cuenta la gran demanda del recurso sobre las cuencas hidrográficas, el alto grado de contaminación de las fuentes superficiales y los elevados costos por el consumo de agua potable en una institución educativa. Este proyecto presenta la ingeniería conceptual de una propuesta de diseño de un si stema de aprovechamiento de agua lluvia como alternativa para el ahorro de agua potable en usos tales como la descarga de sanitarios, el lavado de zonas comunes, entre otros. Se presenta, adicionalmente, un análisis aproximado de la viabilidad técnica y económica de dicho aprovechamiento en una institución educativa del municipio de Caldas, Antioquia. Se desarrollan en este documento tres aspectos principales: el cálculo de los volúmenes disponibles de agua lluvia en la zona, la evaluación del volumen de agua potable ahorrado con el aprovechamiento del agua lluvia, la estimación del presupuesto para la construcción del sistema y la proyección del ahorro generado al utilizarlo. Los resultados sugieren que el aprovechamiento de agua lluvia es una opción técnicamente viable, pero financieramente no, pues la inversión inicial es alta, por lo que es importante buscar financiación externa para desarrollar este tipo de proyectos que representan una solución interesante para contribuir al desarrollo sostenible de la institución educativa.

    The project of installation of speed variator in fossil power stations (CT's) of Comision Federal de Electricidad (CFE), as an energy saving measure, is a pilot project that began with the support of the Subdivision de Generacion, and promoted by the Energy Saving Program of the Electric Sector (PAESE), with the putting in operation of an equipment in the condensate pump of the Punta Prieta II C. T. U3. The energy saving observed was substantial, fluctuating between the 19.4% at high loads (at 90% load) and the 71.1% at low loads (at 40% load) of the generating unit. With these results, it was decided to extend the scope of the project with the installation of 6 more equipment for equal number of fossil power stations, located in 4 of the 5 Regions of Generation. The fossil power stations, selected for this stage of the project were: C. T. Felipe Carrillo Puerto U1, C.T. Lerma U4, C.T. Salamanca U1, C.T. Monterrey U6, C.T. Francisco Villa U3 and the C.T. Punta Prieta II-U1. The equipment was in operation during the first quarter of 1998, and the first results indicate an energy savings average per equipment, between 39% and 52%. The recovery of the investment fluctuates between the 48.4% and the 87.6% in less than two years of operation, with which a maximum period of recovery of 3 years is expected. The estimated potential of energy saving, considering the application of these devices in condensate pumps, feedwater pumps (where no speed variator is installed) forced draft fans, induced draft fans and gas recirculation fans, as well as circulation water pumps, of the existing Generating Power stations, ascends to an annual total of 830,000, which represents an approximate 9.4% of the National consumption of self services.

    In this chapter, Ole B. Jensen takes a situational approach to mobilities to examine how ordinary life activities are structured by technology and design. Using “staging mobilities” as a theoretical approach, Jensen considers mobilities as overlapping, actions, interactions and decisions by desig...... by providing ideas about future research for investigating mobilities in situ as a kind of “staging,” which he notes is influenced by the “material turn” in social sciences....... with a brief description of how movement is studied within social sciences after the “mobilities turn” versus the idea of physical movement in transport geography and engineering. He then explains how “mobilities design” was derived from connections between traffic and architecture. Jensen concludes...

    Full Text Available Las cajas de ahorros Españolas son posiblemente el caso más significativo a nivel mundial de entidades multistakeholders, no sólo por su misión, sino también en su gobernanza. La teoría multifiduciaria de los stakeholders plantea, al menos de forma teórica lo que en las cajas de ahorros ha sido una realidad por más de un siglo. Así, las cajas se convierten en un “caso de laboratorio” para analizar la viabilidad e idoneidad de una gobernanza participada por el conjunto de stakeholders de la organización. Nuestra hipótesis es que la gobernanza multistakeholder, así como la orientación hacia los stakeholders, generan un planteamiento estratégico diferente, no centrado en los beneficios. Por tanto, la gobernanza multifiduciaria puede perfectamente ser más ineficiente en relación con indicadores económico-financieros referidos a los shareholders de una entidad. Sin embargo, estas entidades deberían ser más eficientes si se tienen en cuenta indicadores relacionados con la generación de valor social. Con el fin de contrastar la eficiencia relativa hemos utilizando la población de bancos y cajas de España y los datos de 2009, utilizando la técnica de Análisis Envolvente de Datos con objeto de comparar la eficiencia económica, social y global de ambos tipos de entidades. Los resultados indican una diferenciación significativa entre estos dos grupos de entidades financieras en relación con la eficiencia social y económica, si bien no ocurre lo mismo cuando se utiliza la eficiencia global –económica más social-. Por lo que podemos concluir que la eficiencia en la gestión entre inputs y outputs en cajas de ahorros y bancos es similar. / Probably, Spanish savings banks are the most significant worldwide multistakeholders entities, not only because of their mission, but also in their governance. The stakeholder multifiduciary theory, establishes at least theoretically what the saving banks has been a reality for more than

    Full Text Available El trabajo estudia el comportamiento de la tasa de ahorro de los hogares en el período de 1985 a 2016. Se examinan las variables que la literatura considera que determinan la tasa de ahorro a largo plazo: renta, riqueza, desempleo, crédito y endeudamiento, ahorro público, estructura de la población, prestaciones sociales, tipos de interés y precios. Tras revisar la cointegración de las variables elegidas, proponemos cuatro especificaciones de la tasa de ahorro en función de sus determinantes a largo plazo: la renta permanente, la riqueza, el desempleo, el crédito, la tasa de dependencia y las prestaciones sociales. En el marco del modelo de corrección de error, contrastamos complementariamente la cointegración de las variables que confirman la validez del modelo. Los resultados muestran la especial relevancia a largo plazo de la tasa de dependencia que, como variable demográfica estructural, permite prever en cierta medida la evolución de la tasa de ahorro. Las prestaciones sociales, que muestran la importancia a largo plazo del sistema de prestaciones público, junto con el crédito y el desempleo, determinan la tasa de ahorro a largo plazo en consonancia con la fase del ciclo económico. La renta laboral-permanente incide sobre la tasa de ahorro especialmente en los cambios profundos de ciclo. La repercusión a largo plazo de la riqueza es de menor magnitud. || The paper studies the behavior of the household saving rate during the period from 1985 to 2016. We examine the variables considered by the literature to determine the long-term saving rate: Income, wealth, unemployment, credit and indebtedness, public savings, population structure, social benefits, interest rates and prices. In the framework of the error correction model, we contrast the cointegration of the variables by means of four specifications for the saving rate according to its long-term determinants: Permanent income, wealth, unemployment, credit, dependency rate

    Full Text Available This article describes the method used by and oil refinery to save some two hundred thousand dollars in the replacement of a seriously damaged stretch of a pipeline carrying salt water refrigerant. This substantial saving was obtained by installing high density polyethylene pressure pipe as a cover around the damaged pipe section. The same type of piping can be used in other industries (pulp and paper mills, Chemical processes pollution control, mining, textile mills, etc. where worm or abrasion corrosion damaged pipes can be found.

    Este artículo describe el método por el cual una refinería pudo ahorrarse unos doce millones de pesetas en la operación de repuesto de un tramo muy deteriorado de una conducción que transporta agua salada refrigerante. Este ahorro substancial se obtuvo gracias al uso de futras de presión de polietileno, de alta densidad, como revestimiento de la sección deteriorada de la tutoría. El mismo tipo de tubería se puede emplear también en otras industrias (pastas, papel, procesos químicos, control de polución, minería, textil, etcétera donde existan conducciones desgastadas o deterioradas por corrosión o abrasión.

    In here it is presented the analysis of the impact of the solar gains through the transparent parts of a prototype house of social interest, located in a dry warm climate. This analysis was made to determine the gains through windows for the summer time and under the following conditions: without outside solar protections, with the use of eaves, solar breakers and finally with the use of both systems of solar protection. The results were compared to obtain the considered potential of energy saving in cooling equipment, that could be obtained in future houses to build. [Spanish] Se presenta el analisis del impacto de las ganancias solares a traves de las partes transparentes de un prototipo de vivienda de interes social, ubicado en un clima calido seco. Dicho analisis se realizo para determinar las ganancias a traves de ventanas para la epoca de verano y bajo las siguientes condiciones: sin protecciones solares exteriores, con el empleo de aleros, con quiebrasoles y finalmente con el empleo de ambos sistemas de proteccion solar. Se compararon los resultados para obtener el potencial estimado de ahorro de energia en equipo de enfriamiento, que se tendria en las futuras viviendas por construir.

    In this paper the importance that the preventive maintenance has as an important ingredient of the internal policies of the companies for the promotion of the energy saving is discussed. It considers that the department of planning and production control must take into account very seriously the importance of programmed preventive maintenance in order to maintain the continuity of the production process and with this eliminate the bottle necks that adversely affect it and consequently the the company's image before the clients, besides contributing positively the promotion of energy saving. The faults that stop the production process inflict losses of income and adversely affect the yield of the company, in addition, they increase the production cost or the plant expenses associated to the repair of the damaged equipment, in the worst of the cases, important penalties will have to be paid for the delayed delivery of the product to the client. By keeping the correct operation of the equipment, increasing its availability and assuring that all the safeties of these operate correctly we will be contributing to the optimal operation of the enterprise system and avoiding the additional consumption of energy associated to the failure of an equipment and interruption of the production line. The preventive maintenance also promotes, the order and the cleanliness, the safety and hygiene in the work centers and the protection to the environment. Once the prevention has won the battle to the correction, one enters the field of diagnosis, handling the service periods in an optimal way in benefit of the production line. In this stage it can be spoken of entering the application of Total Productive Maintenance.

    This paper shows the results attained in energy saving through a project of potable water pumping, which took an investment of $433,043.00 and an internal rate of return of 126%. This project puts into evidence that it is possible to reduce between 15 and 30% of the total invoicing for energy consumption in potable water pumping if an equipment of poor efficiency is replaced by another of high efficiency. The project was requested by the Guanajuato's State Water Comision and the Municipal Bureau of Sewage and Potable Water, with the double intention of reducing the energy consumption along with the corresponding invoicing and incrementing the output of the wells in order to improve the potable water supply. In the site two high efficiency submersible motor-pumps were installed previously to the energy diagnosis that triggered profitable operation results and a convenient invoicing. [Spanish] Se documentan los resultados obtenidos en un proyecto de ahorro de energia en el bombeo de agua potable realizado con una inversion de $433,043.00 y con una tasa interna de retorno de 126%. Este proyecto pone en evidencia que es posible reducir entre el 15 y 30% de la facturacion total por consumo de energia electrica en el bombeo de agua potable si se sustituye un equipo poco eficiente por otro de alta eficiencia. El proyecto fue solicitado por la Comision Estatal del Agua de Guanajuato y la Junta Municipal de Agua Potable y Alcantarillado del municipio, con un doble proposito, reducir el consumo de energia junto con la facturacion correspondiente e incrementar la capacidad de produccion de los pozos con la intencion de mejorar el abasto de agua potable. En el lugar se instalaron dos motobombas sumergibles de alta eficiencia previo diagnostico energetico que desencadenaron rentables resultados operativos y de facturacion.

    In Mexico, the culture of energy saving began more than one decade ago, but the benefits are not yet concrete. The Mexican society, requires new designs of dwellings adapted to its needs and in addition modifies the present systems of construction that do not include criteria of design for the thermal comfort, the energy saving and the sustainability. It is urgent to reconsider the urbanism of the cities, as well as the promotion of the concept of sustainable development in all the branches of human activity. The design of dwellings must significantly integrate the energy and environmental components to reduce to the power consumption and the CO{sub 2} emissions. [Spanish] En Mexico, la cultura de ahorro de energia se inicio hace mas de una decada, pero los beneficios aun no son palpables. La sociedad mexicana, requiere de nuevos disenos de viviendas que se adapten a sus necesidades y que ademas modifiquen los sistemas de construccion actuales que no incluyen criterios de diseno para el confort termico, el ahorro de energia y la sustentabilidad. Es urgente reconsiderar el urbanismo de las ciudades, asi como la promocion del concepto de desarrollo sustentable en todas las ramas de la actividad humana. El diseno de la vivienda debe integrar los componentes energeticos y medioambientales, para reducir significativamente el consumo de energia y las emisiones de CO{sub 2}.

Las edificaciones estudiadas son iglesias vernaculares de la época de 1901-1950. La metodología permite identificar los factores principales que influyen dentro del comportamiento térmico interior y establecer cuáles modificaciones se pueden implementar para lograr mayor bienestar, tanto en los casos de estudio, como en futuros diseños con condiciones similares. Abstract The present study proposes and implements a methodology to analyze the behavior of existing buildings in response to specific climatic and geographic variables, through the use of digital thermodynamic simulations that allow modifications to improve internal comfort. The analysis was carried out by means of six case studies located in three zones of life of Costa Rica: Tropical Dry Forest (Bs-T, Premontane Wet Forest (Bh-p and Premontane Very Humid Forest (Bmh-p. The buildings studied are vernacular churches dating from 1901-1950. The methodology allows to identify the main factors that influence the internal thermal behavior and to establish which modifications can be implemented to achieve greater welfare, both in the case studies and in future designs with similar conditions.

En este artículo, tras delimitar las unidades de análisis básicas para los sistemas de información de las cajas rurales y las cajas de ahorros, presentamos los resultados obtenidos a través de una encuesta realizada en dichas entidades, al objeto de contrastar la importancia que ostentan dichas unidades de análisis en sus sistemas de información. El estudio empírico llevado a cabo ha puesto de manifiesto que la unidad de análisis por excelencia en ambas categorías de entidades es la oficina, seguida por las direcciones regionales o de zona. Los productos y los clientes presentan un menor grado de implantación en sus sistemas de información, en especial en las cajas rurales. The basic units of analysis for managing Depository Financial Institutions are the central axes where management accounting information should be generated and, consequently, are also formed as an essential instrument to support the managerial decisions. Once the basic analysis units for information systems in the rural and savings banks are defined, we offer the results obtained by means of a survey carried out in the aforementioned institutions. So the relevance of this analysis unit in their information systems may be known. The empirical study carried out has shown that the main analysis unit in both categories of entities is the branch office, followed by regional management. Products and customers have a minor relevance in their information systems, particularly in the rural banks.

    The technological advances generate far reaching changes in all types of installation. The new spaces and the existing ones justify the introduction of new technologies taking into account important economic considerations, mostly when the advantage of daylight is taken into consideration in industrial and commercial lighting. In the daylight design it is necessary to know the solar transit, the atmospheric conditions, the architectural design of the building, the materials and the control elements, etc. to apply with precision the calculation method. The fundamental lighting technic have varied little. In the greatest part of commerces and industries the general lighting is used, that produces an illumination more or less uniform on the working areas, which guarantees a total freedom for the placement of machinery, working benches, racks, exhibitors, clothes racks, etc..

    The Norm NOM-008-ENER-2001 no longer commands the efficient handling of energy from functional equipment or apparatuses but from a well planned architectural design that allows diminishing the energy use for cooling purposes, consequently this Norm refers to the conduction and radiation principles regulating the heat gain through the cover portions of a building. The Norm defines a reference theoretical building that will dictate the propitious heat gain for the projected buildings. Here the functioning logic of the Norm in respect to both principles is mathematically explained as well as an application example is developed considering the calculations made for the Norm's reference building and for the projected one, the final revision of the fulfillment of the norm, proposals of solutions and the conclusions. [Spanish] La Norma NOM-008-ENER-2001 comanda el manejo eficiente de energia electrica ya no a partir de equipos o aparatos funcionales sino a partir de un bien planeado diseno arquitectonico que permita disminuir el uso de energia para fines de enfriamiento.

La Norma define un edificio teorico de referencia que dictara la ganancia de calor propicia para los edificios proyectados. Aqui se explica matematicamente la logica de funcionamiento de la Norma respecto a ambos principios asi como se desarrolla un ejemplo de aplicacion que considera los calculos realizados para el edificio de referencia de la Norma y para el proyectado, la revision final del cumplimiento de la Norma, propuestas de solucion y conclusiones.

[Spanish] Se presentan los resultados de un esfuerzo por contribuir al desarrollo de nuevos elementos constructivos acordes a las necesidades bioclimaticas de las edificaciones en Mexico que propicien el ahorro de energia. Se desarrollaron ventanas con dos tipos de recubrimientos, uno exclusivamente de oxido cuproso (Cu{sub 2}O), y otro resultado del deposito sucesivo de una pelicula de sulfuro cuprico (CuS) sobre otra de oxido cuproso. El segundo tipo de ventanas presento un adecuado control al paso de la radiacion infrarroja, lo que permite reducir aun mas la cantidad de radiacion calorifica que pasa a traves de la ventana. Durante las condiciones de calentamiento, estas ventanas dejan pasar en el peor de los casos, la mitad del calor, reduciendo la carga termica al interior de la habitacion o del edificio. Durante condiciones de enfriamiento, la ventana permite la salida del calor a la mitad de la velocidad, manteniendo durante mas tiempo la temperatura de confort del interior. Los recubrimientos de los mencionados compuestos de cobre fueron fabricados en los laboratorios de los Institutos de Ingenieria y Fisica de la Universidad Nacional Autonoma de Mexico (UNAM). Se utilizo la tecnica de erosion ionica o sputtering de un blanco de cobre 99.999% con ayuda de un plasma compuesto de argon (70%) y oxigeno (30%), que posibilita la oxidacion del cobre y el deposito del Cu{sub 2}O. Se utilizo un sustrato de vidrio flotado comercial de 600x400 mm., este tamano del vidrio estuvo determinado por las limitaciones de espacio de nuestra camara de deposito.

    Full Text Available Objective. To assess the disease burden of rotavirus diarrhea in Peru as well the need for and the potential cost savings with a rotavirus vaccine in that country. Methods. To assess the burden of rotavirus diarrhea in Peru, we reviewed published and unpublished reports where rotavirus was sought as the etiologic agent of diarrhea in children. Rotavirus detection rates obtained from these studies were combined with diarrhea incidence rates from a number of national surveys in order to estimate both the burden of rotavirus diarrhea in the country and its associated medical costs. Results. Rotavirus is a significant cause of morbidity and mortality in Peruvian children. In their first 5 years of life, an estimated 1 in 1.6 children will experience an episode of rotavirus diarrhea, 1 in 9.4 will seek medical care, 1 in 19.7 will require hospitalization, and 1 in 375 will die of the disease. Per year, this represents approximately 384 000 cases, 64 000 clinic visits, 30 000 hospitalizations, and 1 600 deaths. The annual cost of medical care alone for these children is approximately US$ 2.6 million--and that does not take into account the indirect or societal costs of the illness and the deaths. Conclusions. Rotavirus immunization provides the prospect of decreasing the morbidity and mortality from diarrhea in Peru, but a vaccine regimen would have to be relatively inexpensive, a few dollars or less per child. Future cost-effectiveness analyses should explore the total costs (medical as well as indirect or societal associated with rotavirus diarrhea. Newly licensed vaccines should be tested according to both their ability to avert deaths and their efficacy with fewer than three doses. All three of these factors could increase the cost savings associated with a rotavirus vaccine.Objetivos. Evaluar la carga de morbilidad de la diarrea por rotavirus en Perú, la necesidad de una vacuna y el ahorro que esta podría proporcionar en este país. M

    Altos Hornos de Mexico (AHMSA) is an iron and steel industry integrated to Grupo Acereros del Norte in Monclova, in the Coahuila state. With an a installed capacity of 3.1 millions of tons per annum o liquid steel. In its installations, AHMSA has the highest capacity blast furnace installed in Mexico, blast furnace No. 5, that has a useful volume of 2,163 cubic meters, designed to produce 4,800 tons of pig iron per day. The basic goal to achieve in the operations involved in the production of steel through the pig iron production in the blast furnace, is the hot metal production at the lowest attainable cost within the quality requirements specified by the steel makers. The most important criterion for the recognition of the attained success is the fuel consumption per ton of pig iron produced, with coke as the main fuel fed to the blast furnace and therefore of the greatest impact on the final product cost. AHMSA contemplated within its strategic plan, the reduction in the production of its coking plants derived from the natural aging of its furnaces, consequently it is pending the shortage of coke for productions higher than 2.6 MMT of liquid iron. In response to this, and faced to the true need of diminishing the production costs in the process of making pig iron, new practices have been implemented in the use of complementary fuels to partially substitute the metallurgical coke as an energy source for the blast furnace process. The use of natural gas, fuel oil and the gradual increase of the temperature of hot blow, have strongly impacted the metallurgical coke consumption, lowering it considerably and diminishing the costs per ton of pig iron in blast furnace No. 5. Another important issue, is the utilization of coke fines resulting form the sieving of the same, directly fed to the furnace load. This practice reduced the coke consumption, and most of all, the output of our coking plants was increased on being utilized at the maximum coke production

Su modelo de banca “minorista”, centrada en la cercanía al cliente, se ha visto acompañado en los últimos años de un fuerte proceso de expansión geográfica que ha supuesto un sobredimensionamiento de su red de sucursales. Sin embargo, como consecuencia de las actuales circunstancias de la economía española en general, y del sistema bancario en particular, dicha estrategia de desarrollo interno no parece sostenible, siendo necesario que se produzca un redimensionamiento del sector, para ver recuperada la confianza en el sistema y para que éste vuelva a ser considerado como uno de los más solventes del mundo. Bajo este enfoque, el objetivo de este trabajo es analizar las distintas estrategias de expansión territorial desarrolladas por dichas entidades con el objetivo de plasmar su situación actual y comprender por qué es necesaria la reestructuración del sector.

NO{sub x} emissions will increase from 6000 t/a in 2005 to 24,000 t/a in 2025, and CO{sub x} will rise from 3.4 million t/a in 2005 to 12.7 million t/a in 2025. The cost of generation will be affected by changes in the energy matrix, and the use of natural gas will predominate. In absolute values it will increase from $648 million USD in 2005 to $2273 million USD in 2025. The cost will depend on an use up to 70% of natural gas. The proposed goals of the Systemic Planning focused on: a) reduce own uses of electricity during generation, b) reduce electric own uses and electric losses during transmission and distribution, c) reducing the growth of electric consumption in the industrial sector, and d) increasing the share of geothermal energy. In a comparison of the Systemic Planning System with the Prospective, increasing in 500 MW the geothermal installed capacity will increase the investment cost, but the balance of net exports, carbon credits and reduced consumption of natural gas indicates a total savings of $11 billion USD and a decrease of 2.3 million tons of CO{sub x}. The geothermal growth combined with the saving and efficient electrical use was rated the best plan, with a total savings of $13.5 billion USD and a decrease in emissions of 8.5 million tons of CO{sub x}.

    layer strains was evaluated using a completely randomized design, with a 2 × 2 factorial arrangement, and four replicates. The thermal evaluation was performed by analysis of dry air and black globe temperature and relative humidity. For the productive performance analysis, egg production and feed conversion ratio were evaluated. For the egg quality analysis, egg weight, Haugh unit, specific gravity, integrity, clearness and shell thickness were evaluated. No differences on the productive performance between rearing systems were observed. The floor system, when properly projected, can be comparable to the cage system with respect to the productive performance and the egg quality. Moreover, this rearing system could provided better results for egg quality with lesser egg losses although in less favorable thermal comfort conditions. However, mainly for the semi heavy strain, it could result in larger dirty egg percentage.

    Full Text Available The continous appearance of new materials, the general tendency towards lighter structural charges, the increased personal welfare levels, tile extended use of mechanical equipments for environmental conditioning in most of the housings presently being constructed, and the incessant and considerable increase of the organic fuel costs have given rise to a new study, both in scope and precision, of the physical and construction basis of the fundamental problems of living spaces. In addition to the financial and engineering aspects of the separate installations the problem is here approached through three different angles: I. Analysis of the thermophysical characteristics of the materials and structural elements that define and quantify the insulating capacity of these. II. Constructive arrangements suitable for carrying out the architectural projects of the construction elements, in order to obtain their maximum efficiency, as regulators of the negative environmental influences. III. A relative study of existing national and foreign regulations of the hygrothermal needs that the elements and structural spaces must meet to achieve the required comfort within the envisaged budget. Each of the above mentioned items will be dealt with in this Journal from this number onwards.La continua aparición de nuevos materiales, la tendencia general al aligeramiento de las cargas estructurales, el incremento de los niveles individuales de bienestar, la extensión de los equipos mecánicos de acondicionamiento ambiental a la mayoría de las viviendas actualmente en construcción, y e! ininterrumpido y sustancial crecimiento en los costos de los combustibles orgánicos, han dado lugar al replanteamiento, en extensión y profundidad, de las bases físico-constructivas en las que descansa la problemática funcional de los recintos habitacionales.

    Full Text Available Ten-story building on a slope, with following distribution: tellers desks, offices and administrative departments, reserved and rental space, a cafeteria, meeting room, installation rooms and a swimming pool with its corresponding services, located on the top of the building. It also has five basements for supplies, storage and garage. The site is surrounded on all four sides with streets on different levels which permit various entrances and different vertical Communications between floors, which results in an optimum relationship between the passage surface and the usable space, taking full advantage of the space available. The concrete structure, with 8.30 m reticule on the sides, provides sufficient flexibility for adapting the different floors to the different operation schemes. The building offers a special architectural interest as a result of the offset in the upper floors and the contrast achieved in treating the facades, where the dark aluminum of the offices floors is broken by the bodies jutting out of the stairwells and elevators, treated with artificial white stone. The building is topped with a roof made of inclined facing on the last floor, also treated with dark aluminum panels.Este edificio consta de diez plantas sobre rasante, en fas que se distribuyen: una sala de cajas, oficinas y departamentos administrativos, espacios de reserva y alquiler, una cafetería, salón de actos, cuartos de instalaciones, y una piscina, con sus correspondientes servicios, montada en el remate de la edificación. Asimismo cuenta con cinco sótanos destinados a abastecimientos, almacén y garaje. La parcela se halla delimitada en sus cuatro costados por redes viarias a distinto nivel, que permiten la existencia de diversos accesos exteriores, así como distintos núcleos de comunicación vertical entre plantas, de donde resulta una óptima relación entre las superficies de circulación y las útiles, aprovechándose plenamente los espacios. La estructura de hormigón, resuelta con una retícula de 8,30 m de lado, proporciona suficiente flexibilidad a las plantas para la adaptación de distintos esquemas de funcionamiento. El conjunto ofrece un especial interés arquitectónico, debido al retranqueo de las plantas superiores y al contraste logrado en el tratamiento de las fachadas, donde el aluminio oscuro de las plantas de oficinas es interrumpido por los cuerpos salientes de las cajas de escaleras y ascensores, tratados en piedra artificial blanca. El edificio está coronado por una cubierta constituida por los paramentos inclinados de la última planta, tratada, igualmente, con paneles de aluminio oscurecido.

    When design research builds on design practice, it may contribute to both theory and practice of design in ways richer than research that treats design as a topic. Such research, however, faces several tensions that it has to negotiate successfully in order not to lose its character as research....... This paper looks at constructive design research which takes the entanglement of theory and practice as its hallmark, and uses it as a test case in exploring how design researchers can work with theory, methodology, and practice without losing their identity as design researchers. The crux of practice based...... design research is that where classical research is interested in singling out a particular aspect and exploring it in depth, design practice is characterized by balancing numerous concerns in a heterogenous and occasionally paradoxical product.

    Energy Technology Data Exchange (ETDEWEB)

    John, C M

    1982-01-01

    Various technical issues of radioactive waste design are addressed in this paper. Two approaches to repository design considered herein are: (1) design to minimize the disturbance of the hot rock; and (2) designs that intentionally modify the hot rock to insure better containment of the wastes. The latter designs range from construction of a highly impermeable barrier around a spherical cavern to creating a matrix of tunnels and boreholes to form a cage within which the hydraulic pressure is nearly constant. Examples of these design alternatives are described in some detail. It is concluded that proposed designs for repositories illustrate that performance criteria considered acceptable for such facilities can be met by appropriate site selection and repository engineering. With these technically feasible design concepts, it is also felt that socioeconomic and institutional issues can be better resolved. (BLM)

    define conceptual designing as a constructive framing and re-framing activity, which is mediated by and targeted at the creation of new design concepts. Conceptual designing as an approach is valuable for addressing the fuzziness and ambiguity typical of research that explores novel areas with new...... partners, methods and resources. It is by no means a new phenomenon, and the main contribution of the article is the clarification of conceptual designing as a particular approach to designing and researching. The approach embraces openness, resource-construction and collaboration.

  1. ECO DESIGN IN DESIGN PROCESS

    Directory of Open Access Journals (Sweden)

    PRALEA Jeni

    2014-05-01

    Full Text Available Eco-design is a new domain, required by the new trends and existing concerns worldwide, generated by the necessity of adopting new design principles. New design principles require the designer to provide a friendly relationship between concept created, environment and consume. This "friendly" relationship should be valid both at present and in the future, generating new opportunities for product, product components or materials from which it was made. Awareness, by the designer, the importance of this new trend, permits the establishment of concepts that have as their objective the protection of present values and ensuring the legacy of future generations. Ecodesig, by its principles, is involved in the design process, from early stage, the stage of product design. Priority objective of the designers will consist in reducing the negative effects on the environment through the entire life cycle and after it is taken out of use. The main aspects of the eco-design will consider extending product exploitation, make better use of materials, reduction of emission of waste. The design process in the "eco"domein must be started by selecting the function of the concept, materials and technological processes, causing the shape of macro and micro geometric of the product through an analysis that involves optimizing and streamlining the product. This paper presents the design process of a cross-sports footwear concept, built on the basis of the principles of ecodesign

    In this paper, we identify the nexus between design (architecture, urban design, service design, etc.) and mobilities as a new and emerging research field. In this paper, we apply a “situational mobilities” perspective and take point of departure in the pragmatist question: “What design decisions...... and interventions affords this particular mobile situation?” The paper presents the contours of an emerging research agenda within mobilities research. The advent of “mobilities design” as an emerging research field points towards a critical interest in the material as well as practical consequences of contemporary......-making. The paper proposes that increased understanding of the material affordances facilitated through design provides important insight to planning and policymaking that at times might be in risk of becoming too detached from the everyday life of the mobile subject within contemporary mobilities landscapes....

    In the Mexico's National Energy Balance of 2008, it is considered that of the total of the electrical power consumption in our country, 18% is dedicated to lighting. Conscious of the necessity of saving energy in public lighting in this article is presented the design, construction and analysis of the power consumption of a public light fed with electricity of photovoltaic cells and the control of intensity on the light in inverse way of the natural light. A lamp constructed based in light emitting diodes (LEDs) is used. This has the quality of consuming very little energy that could be provided by the sun and be stored to use it at night. With this system, proven at scale, energy savings are obtained superior to 50% of the conventional one and, in relation to the commercial photovoltaic (FV) luminaries up to 30%. [Spanish] Del Balance Nacional de Energia, de Mexico, de 2008, se considera que del total del consumo de energia electrica en nuestro pais, el 18% esta dedicado a la iluminacion.

    International Nuclear Information System (INIS)

    1992-01-01

    This paper reports that aboveground tanks can be designed with innovative changes to complement the environment. Tanks can be constructed to eliminate the vapor and odor emanating from their contents. Aboveground tanks are sometimes considered eyesores, and in some areas the landscaping has to be improved before they are tolerated. A more universal concern, however, is the vapor or odor that emanates from the tanks as a result of the materials being sorted. The assertive posture some segments of the public now take may eventually force legislatures to classify certain vapors as hazardous pollutants or simply health risks. In any case, responsibility will be leveled at the corporation and subsequent remedy could increase cost beyond preventive measures. The new approach to design and construction of aboveground tanks will forestall any panic which might be induced or perceived by environmentalists. Recently, actions by local authorities and complaining residents were sufficient to cause a corporation to curtail odorous emissions through a change in tank design. The tank design change eliminated the odor from fuel oil vapor thus removing the threat to the environment that the residents perceived. The design includes reinforcement to the tank structure and the addition of an adsorption section. This section allows the tanks to function without any limitation and their contents do not foul the environment. The vapor and odor control was completed successfully on 6,000,000 gallon capacity tanks

    Brown, Tim

    2008-06-01

    In the past, design has most often occurred fairly far downstream in the development process and has focused on making new products aesthetically attractive or enhancing brand perception through smart, evocative advertising. Today, as innovation's terrain expands to encompass human-centered processes and services as well as products, companies are asking designers to create ideas rather than to simply dress them up. Brown, the CEO and president of the innovation and design firm IDEO, is a leading proponent of design thinking--a method of meeting people's needs and desires in a technologically feasible and strategically viable way. In this article he offers several intriguing examples of the discipline at work. One involves a collaboration between frontline employees from health care provider Kaiser Permanente and Brown's firm to reengineer nursing-staff shift changes at four Kaiser hospitals. Close observation of actual shift changes, combined with brainstorming and rapid prototyping, produced new procedures and software that radically streamlined information exchange between shifts. The result was more time for nursing, better-informed patient care, and a happier nursing staff. Another involves the Japanese bicycle components manufacturer Shimano, which worked with IDEO to learn why 90% of American adults don't ride bikes. The interdisciplinary project team discovered that intimidating retail experiences, the complexity and cost of sophisticated bikes, and the danger of cycling on heavily trafficked roads had overshadowed people's happy memories of childhood biking. So the team created a brand concept--"Coasting"--to describe a whole new category of biking and developed new in-store retailing strategies, a public relations campaign to identify safe places to cycle, and a reference design to inspire designers at the companies that went on to manufacture Coasting bikes.

    JAERI established the safety design philosophy of the HTTR based on that of current reactors such as LWR in Japan, considering inherent safety features of the HTTR. The strategy of defense in depth was implemented so that the safety engineering functions such as control of reactivity, removal of residual heat and confinement of fission products shall be well performed to ensure safety. However, unlike the LWR, the inherent design features of the high-temperature gas-cooled reactor (HTGR) enables the HTTR meet stringent regulatory criteria without much dependence on active safety systems. On the other hand, the safety in an accident typical to the HTGR such as the depressurization accident initiated by a primary pipe rupture shall be ensured. The safety design philosophy of the HTTR considers these unique features appropriately and is expected to be the basis for future Japanese HTGRs. This paper describes the safety design philosophy and safety evaluation procedure of the HTTR especially focusing on unique considerations to the HTTR. Also, experiences obtained from an HTTR safety review and R and D needs for establishing the safety philosophy for the future HTGRs are reported

    The particle beam of the SXR (soft x-ray) beam line in the LCLS (Linac Coherent Light Source) has a high intensity in order to penetrate through samples at the atomic level. However, the intensity is so high that many experiments fail because of severe damage. To correct this issue, attenuators are put into the beam line to reduce this intensity to a level suitable for experimentation. Attenuation is defined as 'the gradual loss in intensity of any flux through a medium' by [1]. It is found that Beryllium and Boron Carbide can survive the intensity of the beam. At very thin films, both of these materials work very well as filters for reducing the beam intensity. Using a total of 12 filters, the first 9 being made of Beryllium and the rest made of Boron Carbide, the beam's energy range of photons can be attenuated between 800 eV and 9000 eV. The design of the filters allows attenuation for different beam intensities so that experiments can obtain different intensities from the beam if desired. The step of attenuation varies, but is relative to the thickness of the filter as a power function of 2. A relationship for this is f(n) = x{sub 0}2{sup n} where n is the step of attenuation desired and x{sub 0} is the initial thickness of the material. To allow for this desired variation, a mechanism must be designed within the test chamber. This is visualized using a 3D computer aided design modeling tool known as Solid Edge.

    This article is about two important scopes of the Bioclimatical Design (BD), the Social scope and the environmental scope. As an introduction, it is justified the importance of this topic through the association of the BD in the context of sustainability with our country's economic model. The analysis is done under the perspective of effects of the BD on social and environmental scopes. In social scope is used the Cost and Benefit Analysis according to social evaluation. In environmental scope, effects in water, air and ground are studied, but the measurement is done according to the emissions reduction of CO{sub 2} on atmosphere because of the earn on energy consumption. The results of the measurement of this effects are related with economical costs and benefits, which may show a general view about economical, social and environmental scopes. As conclusions, interest results are show and this is proposed to incorporate them in the economical politics. [Spanish] En este articulo se tocan dos aspectos importantes del Diseno Bioclimatico (DB), el Impacto Social y el Impacto Ambiental.

El estudio se realiza bajo la perspectiva de los impactos que el DB tiene en el aspecto social y en el ambiental. En lo social, se recurre a la metodologia del Analisis Costo-Beneficio para evaluacion Social, en lo ambiental, aunque se tocan los puntos de impacto en aire, agua y uso de suelo, la medicion del impacto se realiza con base en la disminucion de emisiones de CO{sub 2} a la atmosfera por el ahorro en el consumo de energia electrica. Los resultados de la medicion de impactos se cruzan con los costos y beneficios economicos, para presentar un panorama completo en cuanto a aspectos economicos, sociales y ambientales.

    The current state of the electric power industry in Ontario was discussed with particular reference to the procurement of contracts and why the Ontario Power Authority (OPA) must be contracting to resolve many of Ontario's electricity issues. As Ontario increasingly relies on imports and natural gas-fired generation, the price of electricity continues to rise given that supply is at a low level. In addition to the generation gap, there are also several transmission constrained areas in Ontario, particularly in the Greater Toronto Area (GTA). The OPA announced 2 projects totalling 1900 MW to relieve congestion. According to the Independent Electricity System Operator (IESO), the total potential opportunity for new generation by 2015 is about 5,000 to 7,000 megawatts. OPA is expected to launch procurement processes for up to 1000 MW of cogeneration, 250 MW of province-wide conservation initiatives, 1900 MW of generation in the western part of the GTA, and 600 MW of generation in downtown Toronto. New nuclear capacity is also anticipated in addition to renewables and conservation/demand management (CDM) initiatives. The OPA's competitive procurement processes will include requests for expressions of interest, requests for qualifications and requests for proposals. The challenge of balancing the technical complexities and realities of procuring generation assets with the need for a fair procurement process was discussed. Contracts will be designed to react to market signals and will include 3 styles: tariff style, tolling style and standard offer contract. OPA will make every effort to balance generator and ratepayer interests. 6 figs

    The development of biomedical equipment is justifiably focused on making products that "work." However, this approach leaves many of the people affected by these designs (operators, patients, etc.) with little or no representation when it comes to the design of these products. Industrial design is a "user focused" profession which takes into account the needs of diverse groups when making design decisions. The authors propose that biomedical equipment design can be enhanced, made more user and patient "friendly" by adopting the industrial design approach to researching, analyzing, and ultimately designing biomedical products.

These new demands call for new design rules for coordination, incentives and leadership, among others. Our existing rules are mostly based upon past experience and empirical studies of what is. What might be – going beyond what we have observed and explained of yesterday and today to help design...... for a future new situation – is a disciplined response to examine the new contingencies of organizational design and their design consequences. Computational laboratories permit us to go beyond what is to develop and examine new design possibilities and boundaries to explore a future world of what might be. We...

    The cement plant Cruz Azul S.C.L. is located in the center of the Mexican republic at 70 km north of the capital. Nowadays the Direction of Cementos Cruz Azul has implemented measures allowing to reduce their production costs. The optimization department found a great area of opportunity at the ventilators of the plant. The ventilators are used in different stages of the process and their flow was normally controlled by means of dampers -due to the high costs of the initial investment and that of maintenance of the speed variation technology which in its majority used direct current equipments. In this case it existed the possibility of making a successful application in two large ventilators, with motors of 1000 HP fed in medium tension (4160 v) in our calcination unit Num. 8. This document shows the development of this project from its initial analysis to its application and results.

    The efficient handling of the economic and natural resources of the municipalities, is nowadays so much complex, that it requires a formal planning. In the public service of potable water supply, two fundamental approaches are conjugated to consider: the rational use of the water resource and the efficient use of the electrical energy, for its extraction from the underground deep reservoirs. In the paper that is presented, the individual features of the previous matters are described and the positive results in a municipality of the Guanajuato's Low Lands (Bajio ), where already the dual objectives are obtained and that with a more professional municipal hydraulic planning, these will be permanent, with the inherent benefit towards the population. [Spanish] El manejo eficiente de los recursos economicos y naturales de los municipios, es hoy en dia cada vez mas complejo, que requiere una planeacion formal. En el servicio publico de abastecimiento de agua potable, se conjugan dos enfoques primordiales a considerar: el uso racional del recurso agua y la utilizacion eficiente de la energia electrica, para su extraccion de los acuiferos subterraneos profundos. En el trabajo que se presenta, se describen las particularidades de lo anterior y los resultados positivos en un municipio del Bajio guanajuatense, donde ya se logran los objetivos duales y que con una planeacion hidraulica municipal mas profesional, estos seran permanentes, con el beneficio inherente hacia la poblacion.

    Although the use of computer aids to develop integrated circuits is relatively new at Sandia, the program has been very successful. The results have verified the utility of the in-house CAD design capability. Custom IC's have been developed in much shorter times than available through semiconductor device manufacturers. In addition, security problems were minimized and a saving was realized in circuit cost. The custom CMOS IC's were designed at less than half the cost of designing with conventional techniques. In addition to the computer aided design, the prototype fabrication and testing capability provided by the semiconductor development laboratory and microelectronics computer network allows the circuits to be fabricated and evaluated before the designs are transferred to the commercial semiconductor manufacturers for production. The Sandia design and prototype fabrication facilities provide the capability of complete custom integrated circuit development entirely within the ERDA laboratories

    Ergonomics are rarely addressed directly in the design and re-design of workspaces in Denmark. Often architects, engineers and other actors design the workspaces on the basis of for example spatial, technological or finan-cial considerations, thereby making ergonomics a by-product of the design...... process. However, by introducing ergonomists in the role of ‘workspace de-signers’ early in the design process, ergonomic considerations as well as the involvement of employees, can be integrated in the design process. In this article we demonstrate the use of the workspace design approach in a case study...... where an industrial manufacturer is undergoing a major technological change: going from labour intensive manual work to a highly automated production. The workspace design team, which included the company’s OHS consultant, designed the intervention as a participatory design process by using visually...

    2012-01-01

    Game design is an art form that deals with inherently interactive artifacts. Game designers craft games (assembled from rule systems and content), but they really seek to manipulate play: the interaction between games and players. When developing new games that are similar to past games, a designer may rely on previous experience with related designs and relatively easy access to players familiar with conventional design choices. When exploratorily venturing into uncharted territory, uncoveri...

  5. Control system design guide

    Energy Technology Data Exchange (ETDEWEB)

    Sellers, David; Friedman, Hannah; Haasl, Tudi; Bourassa, Norman; Piette, Mary Ann

    2003-05-01

    The ''Control System Design Guide'' (Design Guide) provides methods and recommendations for the control system design process and control point selection and installation. Control systems are often the most problematic system in a building. A good design process that takes into account maintenance, operation, and commissioning can lead to a smoothly operating and efficient building. To this end, the Design Guide provides a toolbox of templates for improving control system design and specification. HVAC designers are the primary audience for the Design Guide. The control design process it presents will help produce well-designed control systems that achieve efficient and robust operation. The spreadsheet examples for control valve schedules, damper schedules, and points lists can streamline the use of the control system design concepts set forth in the Design Guide by providing convenient starting points from which designers can build. Although each reader brings their own unique questions to the text, the Design Guide contains information that designers, commissioning providers, operators, and owners will find useful.

    1998-01-01

    Representing computer applications and their use is an important aspect of design. In various ways, designers need to externalize design proposals and present them to other designers, users, or managers. This article deals with understanding design representations and the work they do in design....... The article is based on a series of theoretical concepts coming out of studies of scientific and other work practices and on practical experiences from design of computer applications. The article presents alternatives to the ideas that design representations are mappings of present or future work situations...... and computer applications. It suggests that representations are primarily containers of ideas and that representation is situated at the same time as representations are crossing boundaries between various design and use activities. As such, representations should be carriers of their own contexts regarding...

    Balint, Tibor S.; Freeman, Anthony

    2017-08-01

    NASA is a dynamic and living organization. Looking at it through the optics of cybernetics, we can describe it as an autopoietic system. It has to sustain itself, and compete successfully to be viable. Its organizational elements have to interact with the broader environment by maintaining and improving its processes that generate the means for future sustainability. It also needs to bring up follow-on generations who are not simply aligning with the status quo, but also improve the system's viability. For government-run programs, organizational, programmatic and project management practices are often rigidly linear. They can be characterized as observed first-order cybernetic systems, where the paradigm is bound by well-established requirements. At the implementation level this does not readily accommodate flexibility and change. To address this, broadening the system's worldview is needed from the strategic level. This corresponds to an observing second-order cybernetic system, where strategic leadership can overwrite the rules of a first-order system. Changing the worldview of an organization can be complex and face much resistance. Still, with the appropriate strategic-level support, it can be achieved by introducing novel languages, new perspectives, and adding new disciplines to existing ones. In effect, this helps to broaden the organizational paradigm, and subsequently influence its mission, impact the culture, and open up its core processes. These changes can be effectively introduced through design conversations in the early formulation stages, when new ideas are conceived. Within NASA's Jet Propulsion Laboratory, early-stage concept developments are performed at a specially formulated environment, called the Innovation Foundry. Within this office, a continuous effort is being made on designing the design processes, which helps to broaden the variety of the option trades. It is achieved by an added focus on conversations and the inclusion of non

    2001-01-01

    Because simplistic designs will lead to prohibitively large sample sizes, the optimization of genetic study designs is critical for successfully mapping genes for complex diseases. Creative designs are necessary for detecting and amplifying the usually weak signals for complex traits. Two important outcomes of a study design--power and resolution--are implicitly tied together by the principle of uncertainty. Overemphasis on either one may lead to suboptimal designs. To achieve optimality for a particular study, therefore, practical measures such as cost-effectiveness must be used to strike a balance between power and resolution. In this light, the myriad of factors involved in study design can be checked for their effects on the ultimate outcomes, and the popular existing designs can be sorted into building blocks that may be useful for particular situations. It is hoped that imaginative construction of novel designs using such building blocks will lead to enhanced efficiency in finding genes for complex human traits.

    CERN Document Server

    Launey, Warwick De

    2011-01-01

    Combinatorial design theory is a source of simply stated, concrete, yet difficult discrete problems, with the Hadamard conjecture being a prime example. It has become clear that many of these problems are essentially algebraic in nature. This book provides a unified vision of the algebraic themes which have developed so far in design theory. These include the applications in design theory of matrix algebra, the automorphism group and its regular subgroups, the composition of smaller designs to make larger designs, and the connection between designs with regular group actions and solutions to group ring equations. Everything is explained at an elementary level in terms of orthogonality sets and pairwise combinatorial designs--new and simple combinatorial notions which cover many of the commonly studied designs. Particular attention is paid to how the main themes apply in the important new context of cocyclic development. Indeed, this book contains a comprehensive account of cocyclic Hadamard matrices.

    1989-01-01

    Improved design techniques are needed to achieve high reliability at minimum cost. This is especially true of space systems where lifetimes of many years without maintenance are needed and severe mass limitations exist. Reliability must be designed into these systems from the start. Techniques are now being explored to structure a formal design process that will be more complete and less expensive. The intent is to integrate the best features of design, reliability analysis, and expert systems to design highly reliable systems to meet stressing needs. Taken into account are the large uncertainties that exist in materials, design models, and fabrication techniques. Expert systems are a convenient method to integrate into the design process a complete definition of all elements that should be considered and an opportunity to integrate the design process with reliability, safety, test engineering, maintenance and operator training. 1 fig

  19. DEEP EMPATHIC DESIGN

    Directory of Open Access Journals (Sweden)

    FRAQUELLI Roberto

    2015-06-01

    Full Text Available Empathic design is often described as a creative process that translates observations - typically of people and their behaviours into design ideas. Another similar and closely related expression is user centred design, which attempts to turn the attention away from an object or product towards its usefulness and usability. The central premise of empathic design is that the best-designed products and services result from understanding the needs of the people who will use them. User-centred designers engage actively with end-users to gather insights that drive design from the earliest stages of product and service development, right through the design process.[1] Our standard definitions and understanding of empathic design or user centred design are well recognised and widely practiced, particularly taught in design schools and in professional creative business. This paper extends and explores a deeper understanding of empathy within a systems thinking framework where the observer and subject are both components of empathic design. It proposes that empathy can be described as the bonds of connection with others (in its traditional interpretation, but also with an ecological, social and economic context.

  1. Designing synthetic biology.

    Science.gov (United States)

    Agapakis, Christina M

    2014-03-21

    Synthetic biology is frequently defined as the application of engineering design principles to biology. Such principles are intended to streamline the practice of biological engineering, to shorten the time required to design, build, and test synthetic gene networks. This streamlining of iterative design cycles can facilitate the future construction of biological systems for a range of applications in the production of fuels, foods, materials, and medicines. The promise of these potential applications as well as the emphasis on design has prompted critical reflection on synthetic biology from design theorists and practicing designers from many fields, who can bring valuable perspectives to the discipline. While interdisciplinary connections between biologists and engineers have built synthetic biology via the science and the technology of biology, interdisciplinary collaboration with artists, designers, and social theorists can provide insight on the connections between technology and society. Such collaborations can open up new avenues and new principles for research and design, as well as shed new light on the challenging context-dependence-both biological and social-that face living technologies at many scales. This review is inspired by the session titled "Design and Synthetic Biology: Connecting People and Technology" at Synthetic Biology 6.0 and covers a range of literature on design practice in synthetic biology and beyond. Critical engagement with how design is used to shape the discipline opens up new possibilities for how we might design the future of synthetic biology.

  10. Situating universal design architecture: designing with whom?

    Science.gov (United States)

    Jones, Paul

    2014-01-01

    To respond to growing calls for a theoretical unpacking of Universal Design (UD), a disparate movement cohering around attempts to design spaces and technologies that seek to allow use by all people (to the fullest extent possible). The on-going embedding of UD into architectural practice and pedagogy represents an opportune juncture at which to draw learning from other distinct-but-related transformatory architectural movements. Sociological-theoretical commentary. UD has to date, and necessarily, been dominated by the practice contexts from which it emerged. Appealing as a short-hand for description of "designing-for-all", in most cases UD has come to stand in as a term to signal a general intent in this direction and as an umbrella term for the range of technical design resources that have been developed under these auspices. There remains a fundamental ambivalence vis-à-vis the question of users' power/capacity to influence decision-making in the design process in UD; technically-oriented typologies of bodies predominate in influential UD architectural accounts. UD represents rich technical and pedagogical resources for those architects committed to transforming the existing built environment so as to be less hostile to a wide range of users. However, within UD, unpacking the social role of the professional architect vis-à-vis a variety of publics is an important, but hitherto underdeveloped, challenge; issues concerning professional-citizen power relations continue to animate parallel architectural politics, and UD can both contribute and draw much from these on-going explorations. Implications for Rehabilitation Universal Design (UD) architecture shares a close affinity with rehabilitation practice, with the creation of built environments that allow use by individuals with a wide range of capacities a priority for both. While an effective communicative "bridge" between professions, UD's deployment typically leaves unspoken the capacity of users to

  11. Enhanced Design Alternative I: Low Temperature Design

    International Nuclear Information System (INIS)

    MacNeil, K.

    1999-01-01

    The purpose of this document is to evaluate Enhanced Design Alternative (EDA) 1, the low temperature repository design concept (CRWMS M and O 1999a). This technical document will provide supporting information for Site Recommendation (SR) and License Application (LA). Preparation of this evaluation will be in accordance with the technical document preparation plan (TDPP), (CRWMS M and O 1999b). EDA 1, one of five EDAs, was evolved from evaluation of a series of design features and alternatives developed during the first phase of the License Application Design Selection (LADS) process. Low, medium, and high temperature concepts were developed from the design features and alternatives prepared during Phase 1 of the LADS effort (CRWMS M and O 1999a). EDA 1 will first be evaluated against a single Screening Criterion, outlined in CRWMS M and O 1999a, which addresses post-closure performance of the repository. The performance of the repository is defined quantitatively as the peak radiological dose rate to an average individual of a critical group at a distance of 20 km from the repository site within 10,000 years. To satisfy this criterion the peak dose rate must not exceed the anticipated regulatory level of 25 mrem/yr within 10,000 years. If the EDA meets the screening criterion, the EDA will be further evaluated against the LADS Phase 2 Evaluation Criteria contained in CRWMS M and O 1999a

    Full Text Available Much progress has been made in creating informal learning spaces that incorporate technology and flexibly support a variety of activities. This progress has been principally in designing the right combination of furniture, technology, and space. However, colleges and universities do not design services within learning spaces with nearly the same level of sophistication or integration. Nor do they adequately assess their services. This paper calls for a focus on designing services to facilitate better learning experiences. It describes the fundamentals of service design practice, a selection of exemplary spaces, and the implications for design, budgeting, and staffing.

    Full Text Available The notion of design research entails research where design practice forms part of the knowledge production. Based on our characterization of the nature of design, we propose to conceptualize this kind of research as programmatic design research. Two ongoing PhD projects in interaction design are presented as examples of programmatic research processes, highlighting issues to do with the virtues and qualities of the processes, the interplay of optics and engagements in a hermeneutical dynamic, and the production of takeaways for the academic community.
