    An exercise made through an approach group (expert in the subject) identified which were the main perceived obstacles for the penetration of the renewable energies in the Mexican energy sector. The perception of the group is that the perceived obstacles do not tend to be technical and that as of today, they depend more on political-legal aspects, administrative-institutional economic-financial. It is considered that the renewable energies, with some exceptions, were used mainly in a scheme of generating units of useful energy, either electricity or heat-cold or for process or environmental conditioning, are relatively small and therefore with a high dispersion in the national territory. This vision is equivalent to what it is known as distributed generation in the electrical sector. [Spanish] Un ejercicio realizado a traves de un grupo de enfoque (expertos en el tema) identifico cuales eran los principales obstaculos percibidos para la penetracion de las energias renovables en el sector energetico mexicano. La percepcion del grupo es que los obstaculos percibidos no tienden a ser tecnicos y que en el presente, estos dependen mas de aspectos politicos-legales, economicos-financieros y administrativos-institucionales. Se considera que las energias renovables, con algunas excepciones, se utilizaran principalmente en un esquema de unidades generadoras de energia util, ya sea electricidad o calor-frio para proceso o acondicionamiento ambiental, que son relativamente pequenas y por lo tanto con una alta dispersion en el territorio nacional. Esta vision es equivalente a lo que se conoce como generacion distribuida en el sector electrico.

    The long-term vision through scenarios corresponds to different histories of how the energy sector situation could be. The numbers that are obtained are only indicative of those histories and not the quantities of a projection of the future with which businesses plans are to be developed, these quantities serve to illustrate what can happen if certain changes occur either or of geopolitical, economic, technological or social nature. Its main function is the one of making reflect the central actors of the sector on the impacts and consequences that certain events occur. In relation to the renewable energies, in the last decades these have been reducing their participation in the Mexican energy sector. Evidently the Mexican energy sector, in the subject of technology, has decided to take the function of preservative follower due in a large extent to the form in which the management of the operative organizations of the same one is made. [Spanish] La vision a largo plazo a traves de escenarios corresponde a diferentes historias de como podria ser la situacion del sector energia.

Su principal funcion es la de hacer reflexionar a los actores centrales del sector sobre los impactos y consecuencias de que se den ciertos eventos. En relacion con las energias renovables, en las ultimas decadas estas han ido reduciendo su participacion en el sector energetico mexicano. Evidentemente el sector energetico mexicano, en cuestion de tecnologia ha decidido tomar la funcion de seguidor conservador debido en gran parte a la forma en que se realiza la gestion de las entidades operativas del mismo.

    The solar energy manifests itself in different forms and its application has been fundamental for the humankind development. These forms are known as renewable energies, since they are energy forms that are renewed or remade with time or that are so abundant on Earth, that they will last for hundreds or thousands of years, either we use them or not. The main advantage of the utilization of the renewable energies in comparison with hydrocarbons is the one of having smaller impact on the environment, which brings about the conservation of nonrenewable resources, and to postpone its exhaustion. They allow the distributed generation, diminishing the power losses in the transmission and distribution systems, which increases the overall efficiency. In addition they can be the drive for regional development and generation of employment, because when having applications in remote zones and being a field still not completely developed in Mexico, the possibility exists of enabling professionals and technicians. From the point of view of the power sector, the renewable energies extend the supply and availability of energy, making more flexible and independent the operation and reliability of the national power system. [Spanish] La energia solar se manifiesta de diversas formas y su aplicacion ha sido fundamental para el desarrollo de la humanidad. A estas formas se les conoce como energias renovables, ya que son formas de energia que se van renovando o rehaciendo con el tiempo o que son tan abundantes en la tierra, que perduraran por cientos o miles de anos, las usemos o no. La principal ventaja del aprovechamiento de las energias renovables en comparacion con los hidrocarburos es la de tener menor impacto al medio ambiente, lo que trae consigo la conservacion de recursos no renovables, y posponer su termino. Permiten la generacion distribuida, disminuyendo las perdidas energeticas en los sistemas de transmision y distribucion, lo que incrementa la eficiencia general. Ademas

    The high index of economic and technological growth registered in the border zone of northern Mexico in the last years, has simultaneously caused an annual growth in the electrical energy demand in a percentage higher than 6%. In this document are included the economic and environmental impacts caused by the projects developed in the Chihuahua State on energy efficiency and on the available potential of renewable energies. In order to evaluate the environmental impact that is caused when saving electrical energy in the diverse projects in process, the emission of CO{sub 2} is the only emission taken into account (even though also emissions of SO{sub 2}, NO{sub 2} and Hg exist) for being this polluting agent the one that contributes in greater amount to the global warming and the greenhouse effect. The emission index of CO{sub 2} that we considered in this presentation is of 600 kg/mwh, on the basis of the type of fuel and volume of generation of the plants in operation of the Comision Federal de Electricidad (CFE) in the Chihuahua State. [Spanish] El alto indice de crecimiento economico y tecnologico registrado en la zona fronteriza del norte de Mexico en los ultimos anos, ha ocasionado paralelamente un crecimiento en la demanda de energia electrica superior al 6% anual.

    Full Text Available Segundo o IBGE, no ano de 2010, a população brasileira teve um crescimento de 1,12%. Tendo em vista que tal crescimento necessita de uma grande demanda energética, precisa-se de fontes alternativas. Um bom meio supressor é a energia eólica. Meio de energia renovável e limpa. Segundo o documentário, Energia Eólica: a caçada pelos ventos, exibido pela TV Zabelê: “É uma dádiva da natureza o fato da nossa região ter esse grande potencial eólico [...].” No entanto, sua instalação necessita-se de grandes investimentos. Tendo em vista este grande crescimento populacional o projeto de pesquisa Energia Eólica: Uma fonte energética limpa e renovável em nosso meio, tem como objetivo a produção de um pequeno campo de energia eólica, em uma biblioteca na escola Oswaldo Cruz, na cidade de Sinop, Mato Grosso. Desta forma temos a possibilidade de reduzir 70% do consumo energético convencional, proporcionando uma economia financeira considerável. A implantação deste projeto está prevista para o segundo semestre de 2014.

    many environmental obstacles exist. Bolivia, Ecuador and Peru are the South American countries that still have the greatest availability of economically viable water resources to be exploited, since those countries do not even use 7% of the available potential. Venezuela and Paraguay stand out in South America as using more than 50% of the economically available potential for hydroelectric generation in the region. Geothermal energy is an important resource in Mexico and Central America, with an installed capacity of 965 MW and 502 MW in 2008, respectively. In those two cases, this is the primary source of power generation. Argentina's high-enthalpy fields are sufficient for geothermal use to generate energy, but there is no estimate of the generation potential. Chile is another country that tries to develop its geothermal potential. In 2009, the government of Chile requested bids for 20 contracts for geothermal energy exploitation. During the geothermal bidding process, 59 offers from exploitation projects were received and 9 companies were granted licenses for the 20 areas solicited.

    many environmental obstacles exist. Bolivia, Ecuador and Peru are the South American countries that still have the greatest availability of economically viable water resources to be exploited, since those countries do not even use 7% of the available potential. Venezuela and Paraguay stand out in South America as using more than 50% of the economically available potential for hydroelectric generation in the region. Geothermal energy is an important resource in Mexico and Central America, with an installed capacity of 965 MW and 502 MW in 2008, respectively. In those two cases, this is the primary source of power generation. Argentina's high-enthalpy fields are sufficient for geothermal use to generate energy, but there is no estimate of the generation potential. Chile is another country that tries to develop its geothermal potential. In 2009, the government of Chile requested bids for 20 contracts for geothermal energy exploitation. During the geothermal bidding process, 59 offers from exploitation projects were received and 9 companies were granted licenses for the 20 areas solicited.

    The quantification of the different scenarios that have been determined is an exercise that has as an aim illustrating on the interrelation between the parameters that affect the behavior of the energy system, more than having magnitudes on the size of the supply and energy demand for each type of primary energy. The credibility of the numbers is very small due to the many uncertainties in the long-term assumptions. The true value of the exercise is to understand the interrelationship of the different parameters that can affect the system and the impacts that can cause variants of the same. Also it is spoken of the obtained results with LEAP system that are related to the energy demand to year 2030 as well as the composition of the primary energy basket to be used and, the results obtained with the simplified method where, the determination of the demand in 2030 for both scenarios was made in simplified form through the determination of the values of the GIP and those of the energy intensity, being based on the rates of growth supposed for these two parameters in both periods to be considered. [Spanish] La cuantificacion de los diferentes escenarios que se han determinado es un ejercicio que tiene como fin el ilustrar sobre la interrelacion entre los parametros que afectan el comportamiento del sistema energetico, mas que el tener magnitudes sobre el tamano de la oferta y demanda energetica para cada tipo de energetico primario. La credibilidad de los numeros es muy pequena debido a las grandes incertidumbres en los supuestos a largo plazo. El verdadero valor del ejercicio es entender la interrelacion de los diferentes parametros que pueden afectar al sistema y los impactos que pueden causar variantes de los mismos. Tambien se habla de los resultados obtenidos con el sistema LEAP que se encuentran relacionados con la demanda energetica al 2030 asi como la composicion de la canasta de energeticos primarios a utilizarse y, los resultados obtenidos con el metodo simplificado en donde, la determinacion de la demanda en 2030 para los dos escenarios se realizo en forma simplificada a traves de determinar los valores del PIB y los de la intensidad energetica, basandose en las tasas de crecimiento supuestos para estos dos parametros en los dos periodos a considerar.

    The LEAP simulation model requires the values of some exogenous variables: At international level, the population increase, the economic growth and the international oil prices; at domestic level, the population increase, the economic growth, the energy intensity, the elasticity of demand of energy-price, and the elasticity of energy demand-gross national product. The use of the LEAP model for the estimation of the penetration of the renewable energies in Mexico comprises of the requirements established in the study. To estimate the future long term values of variables as the exogenous ones required by this model by means of expert opinion can be, given the nature of same, equally or more complicated and speculative than to directly consider the future rates of penetration of the renewable energies. In order to reflect on the future values of these variables a group of approach with experts was integrated. [Spanish] El modelo de simulacion LEAP requiere los valores de algunas variables exogenas: A nivel internacional, el crecimiento demografico, el crecimiento economico y los precios internacionales del petroleo; a nivel nacional, el crecimiento demografico, el crecimiento economico, la intensidad energetica, la elasticidad de demanda de energia-precio, y la elasticidad de demanda de energia-producto interno bruto. El uso del modelo LEAP para la estimacion de la penetracion de las energias renovables en Mexico forma parte de los requerimientos establecidos en el estudio. Estimar los futuros valores a largo plazo de variables como las exogenas requeridas por dicho modelo mediante opinion experta puede resultar, dada la naturaleza de las mismas, tan o mas complicado y especulativo que estimar las futuras tasas de penetracion de las energias renovables directamente. Para reflexionar sobre los futuros valores de dichas variables se integro un grupo de enfoque con expertos.

    In the last years much attention has been given to the polluting gas discharges, in special of those that favor the green house effect (GHE), due to the negative sequels that its concentration causes to the atmosphere, particularly as the cause of the increase in the overall temperature of the planet, which has been denominated world-wide climatic change. There are many activities that allow to lessen or to elude the GHE gas emissions, and with the main ones the so-called projects of Energy Efficiency and Renewable Energy (EE/RE) have been structured. In order to carry out a project within the frame of the MDL, it is necessary to evaluate with quality, precision and transparency, the amount of emissions of GHE gases that are reduced or suppressed thanks to their application. For that reason, in our country we tried different methodologies directed to estimate the CO{sub 2} emissions that are attenuated or eliminated by means of the application of EE/RE projects. [Spanish] En los ultimos anos se ha puesto mucha atencion a las emisiones de gases contaminantes, en especial de los que favorecen el efecto invernadero (GEI), debido a las secuelas negativas que su concentracion ocasiona a la atmosfera, particularmente como causante del aumento en la temperatura general del planeta, en lo que se ha denominado cambio climatico mundial. Existen muchas actividades que permiten aminorar o eludir las emisiones de GEI, y con las principales se han estructurado los llamados proyectos de eficiencia energetica y energia renovables (EE/ER). Para llevar a cabo un proyecto dentro del marco del MDL, es necesario evaluar con calidad, precision y transparencia, la cantidad de emisiones de GEI que se reducen o suprimen gracias a su aplicacion. Por ello, en nuestro pais ensayamos diferentes metodologias encaminadas a estimar las emisiones de CO{sub 2} que se atenuan o eliminan mediante la aplicacion de proyectos de EE/ER.

    The modern societies face diverse environmental problems among which appear the air pollution, the deterioration of seas and coasts, the acidification of soils, acid rain and the climatic change, phenomena, all of them, related in greater or smaller degree to the conventional practices of production and consumption of energy. Specifically, the climatic change puts in risk the well-being of the future generations, and even, the future of the life in the planet. Although uncertainty around the possible repercussions of this phenomenon exists, one knows that one of its main sources is burning of fossil fuels, when affecting the increase of the atmospheric concentrations of greenhouse gases. However, in spite of the achievement that represents the creation of an instrument so sophisticated as the commonly denominated Kyoto Protocol, reluctance on part of some developed countries exists to ratify it and assume their commitments, and in the last session of the Conference of the Parts, (COP-6), celebrated at The Hague, Holland, it was not managed to consolidate to put in action the mechanisms that Kyoto establishes. [Spanish] Las sociedades modernas enfrentan diversos problemas ambientales entre los que figuran la contaminacion del aire, el deterioro de mares y costas, la acidificacion de suelos, la lluvia acida y el cambio climatico, fenomenos, todos ellos, relacionados en mayor o menor medida con las practicas convencionales de produccion y consumo de energia. De manera especifica, el cambio climatico pone en riesgo el bienestar de las futuras generaciones, e incluso, el futuro de la vida en el planeta. Si bien existe incertidumbre en torno a las posibles repercusiones de este fenomeno, se sabe que una de sus principales fuentes es la quema de combustibles fosiles, al incidir en el aumento en las concentraciones atmosfericas de gases invernadero. No obstante, pese al logro que representa la creacion de un instrumento tan sofisticado como el comunmente denominado

    The application of the solar energy requires an evaluation of the solar resource. It is understood by evaluation the determination of the amount of solar energy available to be used in an application; from the point of view of the present applications it is advisable to distinguish two: the direct solar radiation and the diffuse solar radiation, that conform what it is known as the global solar radiation, or hemispheric. All the solar collectors have capacity to use the direct radiation, their capacity to use diffuse radiation depends on the concentration factor of the radiation that characterizes them. Another distinction that can be done is the measurement of different parts from the spectrum. It is not simple to predict the value of the solar radiation in a site or given moment, this has implications in the design of solar facilities, which are constructed to operate during a large number of years. [Spanish] La aplicacion de la energia solar requiere una evaluacion del recurso solar. Se entiende por evaluacion a la determinacion de la cantidad de energia solar disponible para ser utilizada en una aplicacion; desde el punto de vista de las aplicaciones actuales conviene distinguir dos: la radiacion solar directa y la radiacion solar difusa, que conforman lo que se conoce como la radiacion solar global, o hemisferica. Todos los colectores solares tienen capacidad de utilizar la radiacion directa, su capacidad de usar radiacion difusa depende del factor de concentracion de la radiacion que los caracteriza. Otra distincion que se puede hacer es la medicion de diferentes partes del espectro. No es sencillo predecir el valor de la radiacion solar en un sitio o momento dado, esto tiene implicaciones en el diseno de instalaciones solares, las cuales se construyen para operar durante un numero grande de anos.

    Usually one distinguishes two main types of systems of advantage of the solar energy: the photovoltaic and the photo thermal ones. The first ones are those based on the photovoltaic effect, which allows the direct conversion of the energy of the solar radiation in electrical energy. The second ones transform the solar energy into heat, which can be used in a large variety of processes. By the degree of development of both technologies it is advisable to present them in different sections. Also, there is a great variety of technologies of photo thermal systems that we have classified as technologies for the termosolar generation of electrical power, whose temperatures of operation are high, technologies the solar heating at low temperatures and technologies for industrial heat process.

    The application of the solar energy requires an evaluation of the solar resource. It is understood by evaluation the determination of the amount of solar energy available to be used in an application; from the point of view of the present applications it is advisable to distinguish two: the direct solar radiation and the diffuse solar radiation, that conform what it is known as the global solar radiation, or hemispheric. All the solar collectors have capacity to use the direct radiation, their capacity to use diffuse radiation depends on the concentration factor of the radiation that characterizes them. Another distinction that can be done is the measurement of different parts from the spectrum. It is not simple to predict the value of the solar radiation in a site or given moment, this has implications in the design of solar facilities, which are constructed to operate during a large number of years. [Spanish] La aplicacion de la energia solar requiere una evaluacion del recurso solar. Se entiende por evaluacion a la determinacion de la cantidad de energia solar disponible para ser utilizada en una aplicacion; desde el punto de vista de las aplicaciones actuales conviene distinguir dos: la radiacion solar directa y la radiacion solar difusa, que conforman lo que se conoce como la radiacion solar global, o hemisferica. Todos los colectores solares tienen capacidad de utilizar la radiacion directa, su capacidad de usar radiacion difusa depende del factor de concentracion de la radiacion que los caracteriza. Otra distincion que se puede hacer es la medicion de diferentes partes del espectro. No es sencillo predecir el valor de la radiacion solar en un sitio o momento dado, esto tiene implicaciones en el diseno de instalaciones solares, las cuales se construyen para operar durante un numero grande de anos.

A energia eólica é, como a maioria das fontes de energia renovável, uma forma de energia solar, tendo origem no aquecimento da atmosfera pelo sol, que põe em movimento as massas de ar. A rotação da terra, a forma e cobertura da superfície terrestre e os planos de água, influenciam por seu turno o regime dos ventos, ou seja, a velocidade, direção e variabilidade do vento...

  15. The Optimal Time of Renovating a Mall

    OpenAIRE

    K.C. Wong; George Norman

    1994-01-01

    This paper presents a maximization model determining the optimal time at which a mall should be renovated. The analysis is constructed on the assumption of a decreasing rental income over time as a mall ages. It is then shown that the optimal renovation period achieves a balance between the marginal cost and benefits of delaying renovation. We show how this balance is affected by changes in the discount rate, net rental incomes, and renovation costs. Numerical simulations are used to demonstr...

    At present, it is recognized that the advantage of the energy of the wind to generate electricity is an innovating activity of high technology that is being integrated to the electrical sectors of several countries in the context of the energy diversification. The basic concept of the wind power generators suggests simplicity; nevertheless, the enormous machines that nowadays turn the wind energy to electricity, are complex systems since they are integrated by aerodynamic, mechanical, electrical, hydraulic and electronic subsystems, whose development and integration have presented important challenges in the matter of investigation and technological development. It is for this reason that in the last 10 years several governments of industrialized countries and of some developing ones, have remarkably progressed in the restoration of elements of legislation, regulation, and fiscal measures that have opened and impelled the wind power market, in such a way that in those countries the wind power industry has become a very productive activity.

    The actions for the energy efficiency and the utilization of renewable energies are multiple and dispersed, in each one of the energy consumption points of the country. For this reason, two important factors to foment these actions are to promote the social participation and the effective government communication towards the society: energy saving and social participation. One of the main faculties of the National Commission of Energy Saving (CONAE) is to foment the efficiency in the energy use, through actions coordinated with the different agencies and organizations of the Federal Public Administration, with the governments of the federal entities and the municipalities and, through coordinated operations, with the private and social sectors. The CONAE has established mechanisms of coordination and cooperation with the private and social sectors, having fomented programs, projects and actions whose purpose is the energy efficiency, outstanding: 1) Committees and work groups; 2) Cooperation Agreements; 3) the Advisory Council for the Foment of Renewable Energy.

    The total heat flowing from the Earth's interior to the surface is estimated at {approx}42 TW (1012 watts) of which 19% comes from the crust, the 76% comes from the mantle and the 5% comes from the nucleus. The ability to drive the heat of the rocks is very low, causing the need of hundreds of millions of years to exhaust this energy resource. Based on the properties of the renewable heat flow and the long geological times required for its exhaustion, the Earth energy is considered by many scientists as a source of inexhaustible renewable energy, and by its natural availability in all parts of our planet, perhaps the best distributed, together with solar energy. One of the most important advantages of geothermal energy is that its energy can be used not only to generate electric power, but in a large number of applications or direct uses: the heating of buildings, greenhouses or incubators; aquaculture; in various industrial processes (drying products, food packaging, paper manufacturing, chemicals, etc.); balneology for recreational purposes and medicines, and many other applications. In fact, geothermal applications can be integrally one after another or in processes in cascade to fully utilize its energy content.

Basado en las propiedades renovables del flujo de calor y los largos tiempos geologicos requeridos para su agotamiento, la energia de la Tierra es considerada por muchos cientificos como una fuente de energia renovable, practicamente inagotable, y por su disponibilidad natural en todo nuestro planeta, quizas la mejor distribuida, junto con la energia solar.

    Full Text Available A geração de energia elétrica no Brasil é predominantemente renovável, com a geração interna hidráulica sendo superior a 74% do total de sua matriz energética. O racionamento de energia elétrica ocorrido em 2001, devido à falta de chuvas, levou o país a incrementar a participação de fontes alternativas de energia. Esta necessidade por novas fontes de energia faz com que as potencialidades regionais sejam aproveitadas, o que configura a mudança do modelo de geração, passando de geração centralizada para geração distribuída. Dentre as fontes alternativas de energia, a solar apresenta-se como uma fonte bastante promissora para o Brasil, tendo em vista que a maior parte do seu território está localizada próximo à linha do equador, o que acarreta em um dia de maior duração solar. O Rio Grande do Norte (RN tem um dos maiores índices de incidência solar do território brasileiro, o que o torna apto a receber investimentos para a instalação de usinas solares fotovoltaicas.

  1. Building renovations in BIM systems

    Directory of Open Access Journals (Sweden)

    Smutný Marian

    2018-01-01

    Full Text Available Renovation of buildings is a demanding challenge for computer systems. Nowadays, complex 3D models of historic buildings can be scanned and modelled, including sculptural filigrees and stucco decorations with possibility to generate different projections, cross-sections and elevations according to descriptive geometry rules. However, all of this falls within the field of “3D Modelling”. BIM systems work with elements that have to be classified according to their purpose, or according to the way they are realized. The system is then able to sort, filter or group them. Also, it is able to compute their bill of quantity and quality based on their attributes. Last but not least, it has to be able to schematically display civil engineering drawings on the basis of classification of the elements which differ considerably from the display of descriptive geometry. In regular constructions, repeatability and predictability of the links between the elements suit computer systems. Thus, the issue of building renovations in BIM systems is to find a balance between modelling irregular constructions and irregular space arrangements, while maintaining the ability to interact with other BIM elements.

    The varied spheres (political, environmental, economic, scientific and social) day by day are looking for the key issues, which are going to make them to preserve or disappear either in the present or in the future. Therefore, it was carried out the first conversation in the State of Zacatecas, Mexico. Here there were shown different advances related to the renewable energies by those spheres. Generally speaking, it was in this event where there were gather together private and government organs in order to present every issue related to the use and to the promotion of the renewable energies. By these means, it was probed that the renewable energies are: the current market, the groundbreaking technology, the best option friendly-environment, the panacea for the society and for the improvement of the economy of many countries both developing countries and developed countries. The renewable energy topic is seen from different point of views.

  12. Distinctiveness of Initial Preform Properties in Renovation

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Technologies of renovation form a special group of resource-and energy saving technological processes as they are, by definition, already aimed either at increasing resource of the objects satisfying needs of the society life support and practical activities in different spheres, or at extension of their life cycle including a reuse of material from which they are made. Renovation is used where there is a material object, which does not meet requirements of standard or technical documentation.A characteristic feature of the renovation technologies is lack of procedure for a choice of the preform as in all cases an initial preform is the renovation object itself. Thus each object, acting as an initial preform, has the exclusively individual properties, including technological ones.Distinctiveness of renovation object properties is correlated, first of all, with the personified conditions of formation and (or change of condition of their properties in time at all stages of life cycle (production – transportation – warehousing – operation starting with a preform material when manufacturing under all types of loadings (technological and operational. As a result each object forms its "history" of loading and damages and, therefore, its information base which has to consider the phenomenon of “heredity of life cycle”. The term "heredity of life cycle" characterizes information support of object at any moment under review, including both information of technological inheritance, and data of operational heredity.As a result at every moment of time we have a product with a set of new, uncertain properties caused by the phenomena of heredity of life cycle. These properties are individual for each object to be renovated, which changed its status for the status of initial preform for different types of renovation technologies. This is one of the most important distinctions of renovation technology from the technology used to manufacture a new

  15. Kinds of initial billets in renovation technologies

    Directory of Open Access Journals (Sweden)

    V. M. Yaroslavtsev

    2014-01-01

    Full Text Available Nowadays, technologists in charge of repair, restoration, modernization, and utilization of engineering and other tangible objects widely use the concepts "renovation" and "renovation technologies" pioneered at BMSTU. In forming a new field of science these concepts, in the proper sense of the word, are of composite, generalized character. They concern all the activities and technologies aimed at increasing an object resource or its lifecycle extension, including object material recycling.In the cutting-edge renovation technologies an object (part, assembly, machine, etc. damaged in the operating process is considered to be an initial billet. In renovation, one of the most widespread kinds of initial billets is a damaged part.Such a part can be used again, if, for example, it has saved its material properties in full measure while only contact surfaces or parts of these surfaces have become damaged, and at a point of renovation they can be restored for recycling. If a part has lost its initial properties in full bulk of material, it may be reusable in the assemblies and machines with less rigid requirements for material properties.Or in case of properties loss below the permissible level a damaged part-billet is utilized. Thus, the part-billet state at the point of renovation defines the kind of renovation technology and the main (basic technological method to effect on the damaged part, as well as a set and a sequence of technological methods in general manufacturing process of renovation.However renovation technologies are used not only at the repair and restoration stages after operation-service. So, at the manufacturing stage of a new product to provide the quality to raise a resource are applied the same technological methods as renovation technologies for the objects damaged at the stage of operation. Besides, it is known that at the manufacturing stage a part quality depends not only on the last operation, but also on the features of

    Sandin, Paer

    1987-01-01

    Within a few years Stockholm will let all its treated wastewater into the Saltsjoen. The Saltsjoen is the inner part of the Stockholm Archipelago, which is one of the finest recreation areas in Sweden and where many Stockholmians spend a great deal of their leisure time. That is one reason why it is so important that all wastewater is treated before it reaches the recipient. A sewerage system in bad condition means that the risk of not allowed/unplanned overflows is increased. In order to prevent overflows we drafted 'Plan 83' which tells us how our sewerage system shall be constructed in the future and what measures has to be made in the system. Renovations of the existing pipes is one method to get a well functioning sewer system. Today we have made about 50 different objects at a total length of 6000 m. Why do we renovate sewers and why are we attempting to develop methods for pipe renovations?

    In the aftermath of Superstorm Sandy, new attention has been drawn to planning for and mitigating the effects of disasters on laboratory animal facilities. A number of design approaches and solutions can be easily incorporated into a new vivarium, enhancing its ability to withstand and recover from a disaster. Renovating a vivarium poses special challenges, however. Existing conditions in the project area may dictate which approaches or solutions are feasible, and retrofitting is often more complex and expensive than incorporating the same features into new construction. The authors explain how project design teams can evaluate the types of disasters that a renovated facility will need to address and develop a design strategy that responds to these disasters in the most effective way.

    This comprehensive final report for the Swiss Federal Office of Energy (SFOE) presents the results of a study that examined the question of building renewal in Switzerland - should one rebuild or renovate? The report first examines the age-profile of Swiss buildings, defines renewal strategies and ideas, looks at renewal cycles and, in the light of future renewal demands, describes scenarios for replacement with new buildings instead of carrying out total renovations. The housing owners and their methods of management for multiple-apartment housing are described and the various factors involved in making decisions on how to renovate are discussed from the technical, legal and fiscal points of view. The report goes on to examine the ecological and energy aspects of renewal, presenting figures on energy consumption and material flows. Building renewal is also discussed from the social and regional planning points of view. The report is concluded with a discussion on rebuilding or renewal that takes current renewal deficits, costs and social aspects into account and makes recommendations for further action. An appendix presents renewal case studies.

  16. The Strategic-Renovation Banks’ Risks Management

    Directory of Open Access Journals (Sweden)

    2017-04-01

    Full Text Available The article is aimed at developing approaches to implementation of the strategic-renovation risk management. Essence of risk theories was researched, the concept of «risk» in the bank’s management system were analyzed. On the basis of a theoretical generalization of scientific literature and the carried out analysis of existing risk management strategies to ensure the security of banking business, the strategy of renovation management has been selected. Because bank risks are part of the economic risk system, they are complex in their nature. However, given the importance of bank risks, the interpretation of their essence is still a debating matter. In a certain number of cases, their essence is replaced by the cause of occurrence, that is, all the different circumstances, factors that lead to the losses. So today, banks are considering risks, in particular, not only as a source of possible losses, but also as an opportunity to generate additional profits. An algorithm for taking a strategic-renovation decision on the banks’ risks management system has been proposed.

    In this document are presented the technical-economical the present state of the technologies with electricity generation purposes at worldwide level and the technological prospective for the next years. At present it is estimated that in most of the power scenarios at worldwide level the situation will continue with a strong dependency in fossil fuels. The future dynamics of the energy procurement will depend on diverse factors such as energy efficiency, the international norms and regulations derived of the environmental impact and prices of the primary energy sources. The countries of the first world are developing new technologies of compatible character with the environment, with self-consumption intentions and with the vision of establishing new markets of export towards developing countries. In this context, several countries have established R y D programs for the generation of electricity through solar systems using the thermodynamic conversion. [Spanish] En este documento se presenta el estado actual tecnico-economico de las tecnologias con propositos de generacion de electricidad a nivel mundial y la prospectiva tecnologica para los proximos anos. En la actualidad se estima que en la mayoria de los escenarios energeticos a nivel mundial la situacion continuara con una fuerte dependencia de los combustibles fosiles. La dinamica futura del suministro de energia dependera de diversos factores como la eficiencia energetica, las normas y regulaciones derivadas del impacto ambiental y los precios internacionales de los energeticos. Los paises del primer mundo estan desarrollando nuevas tecnologias de caracter compatible con el medio ambiente, con propositos de autoconsumo y con la vision de establecer nuevos mercados de exportacion hacia paises en desarrollo. En este contexto, varios paises han establecido programas de Investigacion y Desarrollo para la generacion de electricidad a traves de sistemas solares utilizando la conversion termodinamica.

    Full Text Available A recente crise financeira global traz consigo efeitos como a redução da atividade econômica e, consequentemente, do consumo de energia. Essa pode ser uma importante oportunidade para reorganizar o sistema energético em bases mais sólidas e sustentáveis: a eficiência, a maior participação das fontes renováveis e a descentralização da produção de energia. O Brasil e outros países em desenvolvimento podem aproveitar a experiência dos países desenvolvidos em eficiência energética, complementando com um programa vigoroso em energias renováveis, particularmente as "modernas" (eólica, solar, biomassa e pequenas hidrelétricas. Entretanto, preocupa o cenário inercial nacional, baseado num aumento da participação das fontes fósseis de energia na matriz, na priorização dos recursos à exploração de petróleo e gás natural e na manutenção de padrões insustentáveis de produção e consumo.The recent global financial crisis brings about effects such as a reduction in the economic activity and consequently in energy consumption. This may be an important opportunity to reorganize the energy system under more solid and sustainable foundations: efficiency, higher share of renewables and decentralized energy production. Brazil and other developing countries can leapfrog the experience acquired by developed nations in energy efficiency, complementing with a vigorous program in renewables, particularly the "modern" (wind, solar, biomass and small hydros. However, there is a concern about the inertial Brazilian scenario, based on an increasing share of fossil fuels in the matrix, in prioritizing resources to oil and gas exploration and in the continuing unsustainable patterns of production and consumption.

    Among the different renewable energy technologies, wind provides better possibilities in regions in which this resource is available. The advantages of wind, as well as solar energy technologies are less or none fuel costs and less environmental impacts. According to the current available technology development, the use of hybrid systems of photovoltaic and wind energy presents large opportunities to cover the energy needs of isolated areas, specially in facilities that don't have connection to the national transmission grid. This study presents the different environmental impacts that hybrid systems have (incorporing the landscape impacts as well as socioeconomical impacts) for the electricity generation in Cuba. We conclude that these systems allow an important power generation in Cuba, and that they have neglected impacts to the environment. The use hybrid systems in Cuba are particularly important in ecotourism facilities and other small industries. [Spanish] Dentro de las posibilidades energeticas y medioambientales de los distintos tipos de energias renovables; la eolica por su caracter limpio e inagotable, permite un gran desarrollo en aquellas areas que cuentan con el potencial necesario para su aplicacion.

    Increase of requirements by the authorities as to the design of reactor protection systems affected in the last years not only plans being under construction, but also resulted in partly spacious extensions and renovations. While working on the extensions and renovations a lot of problems arose: far-reaching performance of newest guidelines and rules in spite of old plant concepts; partly higher degree of redundancy requirements of the new systems in contrast to the present systems; use of present safeguard systems for new accident countermeasures; designation of priorities between present and new functions, especially in view of fault behaviour of present systems; adaptation of the new I and C equipment to the present signalisation-, operation- and information-arrangements under consideration of the present operational philosophy; spatial incorporation of new equipments; construction as to time without expanding of the planned refuelling phases. Because the KWU has planned and constructed such alterations in nearly 10 plants a lot of experience has been gathered. (author)

    Building Brains has been set up by TNO as a cooperative and started September 21, 2009. The aim of the project was to answer the question how the energy consumption in the Netherlands can be reduced by 50% up to 2030 or how the built environment can be made energy-neutral. This issue of the magazine is dedicated to Building Brains project. Four different renovation concepts are compared: energy-neutral renovation that involves the exclusive use of sustainable generated energy;.the application of the passive construction principles; the use of Double Skin Facades; and decentralized facade-integrated installation techniques. Following the results of this study two optimized refurbishment approaches for a zero energy office are designed. [Dutch] Building Brains is een door TNO opgezet samenwerkingsproject dat op 21 september 2009 van start ging. Het doel van het project is antwoord te geven op de vraag hoe tot 2030 het energiegebruik in Nederland kan worden gehalveerd of hoe de gebouwde omgeving energieneutraal kan worden gemaakt. Deze aflevering van het tijdschrift TVVL is vrijwel geheel gewijd aan het Building Brains project. Er is onderzocht hoe verschillende renovatieconcepten scoren. Er zijn vier renovatieconcepten met elkaar vergeleken: energie neutraal renoveren door middel van duurzame energieopwekking, toepassen van het passiefhuisprincipe, toepassen van een tweedehuidfacade en toepassen van een decentrale, gevel-geintegreerde installatie. Uit de studie kwamen twee geoptimaliseerde concepten voor een energieneutrale kantoorrenovatie naar voren.

  8. Sewerage systems: Overflow problems and renovation methods

    Tanttu, Unto [Plancenter Ltd. (Finland)

    1987-12-15

    Total investments in Finland (1984) spent on sewer systems were roughly FIM 590 million. A big share, about 14 % of this sum (FIM 82 million), was spent on rehabilitation of networks. But is this still enough? According to some evaluations the respective amount should be about FIM 500 million for rehabilitation only. So the question, how to keep the performance of sewer networks satisfactory in the future, is really important. The overflow problem is one of the most serious problems caused by old and improperly working sewer systems. Anyhow, several other aspects of a poor condition of sewers are to be seen: - excess hydraulic loading of treatment plants, - normal maintenance and operation (flushing, opening of clogs) increases, and is more expensive, - unexpected renovation works and interruptions in operation cause e.g. troubles in traffic, odour problems in the environment, hygienic hazards etc., - the performance of other underground networks (water pipes, district heating pipes etc.) may be threatened by earth crushings due to old sewers. In this paper a short description of these items is presented as well as a description of the sewer renovation methods used recently in Finland.

    Nuessli, W.

    1991-01-01

    The Indonesian Power Authority is planning to renovate and uprate seven hydropower stations in Java to expand plant life expectancy, ensure operating safety and reliability, and increase power and generation within economical limits. The power plants were constructed in the early 1920s and extended between 1945 and 1950. Their capacities vary between 4 and 20 MW. For the renovation project, Colenco Power Consulting Ltd. is acting as a consultant to PLN. In February 1990, Colenco inspected all seven power plants. The results of the inspections served as the basis for the development of renovation plans for each of the seven hydropower plants. To determine the cost of the proposed renovation plans, appraisers had to determine a method for comparing the value of an existing plant to that of a renovated one. The two different evaluation methods used for these comparisons are the focus of this paper

    This study investigates the impact of energy renovation on the indoor air quality of an apartment building during the heating season. The study was performed in one residential building before and after its renovation. An evaluation of the indoor air quality was performed using objective measurements and a subjective survey. The concentration of CO2 was measured in the bedrooms, and a sampling of the total volatile compounds (TVOC) was performed in the living rooms of the selected apartments. Higher concentrations of CO2 and TVOC were observed in the residential building after its renovation. The concentrations of CO2, and TVOC in some of the cases exceeded the recommended maximum limits, especially after implementing energy-saving measures on the building. The average air exchange rate was visibly higher before the renovation of the building. The current study indicates that large-scale renovations may reduce the quality of an indoor environment in many apartments, especially in the winter season.

    2009-01-01

    The installation or renovation of a cleanroom is an increasing priority among compounders who, to offer sterile preparations, must comply with the most recent version of United States Pharmacopeia revised General Chapter 797 guidelines. To upgrade their pharmacy facilites, many compounders have worked successfully with a large-scale mechanical engineering firm or a specialized construction company dedicated to cleanroom installation. However, a qualified local mechanical contractor with design capability is a valuable and often overlooked resource for the construction of customized stae-of-the-art cleanrooms. In this report, we describe the installation of such a facility in a busy pharmacy and suggest ways in which compounding pharmacists can identify competent local contractors and control the cost of construction and upgrades. The addition of a cleanroom has enabled The Compounding Pharmacy in Hickory, North Carolina, to achieve accreditation from the Pharmacy Compounding Accreditation Board.

The conducted experiments were aimed at analyzing partitions of 120 mm brick mounted gypsum panels while other walls were 520 mm thick and plastered on both sides. Under natural conditions, sound insulation factors of facades were measured and compared according to comfort classes. The obtained results revealed that thick brick walls of 520 mm insulated the sound of 58 decibels (dB (class B. In contrast, 120 mm brick masonry partition reduced sound only to 48 dB which is class E and agrees with the lowest class of sound insulation. We also calculated the sound insulation factor applying three formulas considering the mass law of sound insulation and comparing it with other previous studies. The paper examines and discusses the findings of the performed calculations and measurements.Article in Lithuanian

    There are several new energy sources to produce electricity. One of them is the wind energy, which has reached huge commercialization in worldwide. There are in Mexico some zones with high speed wind, which can be used in a short term. This has been proved by the wind pilot power plant of La Venta, Oaxaca, where production costs of US 4.3 cents per kilowatt-hour (kWh) have been obtained. These costs are among the lowest in the world. By the other hand, among the main uses of solar energy, including both thermal and photovoltaic techniques, the biggest thermo-solar utility, with 350 megawatts (MW) of capacity, is remarkable. This is the plant located in the Mojave Desert, California, USA. In Mexico there is big potential, which can make an important contribution to supplies of electricity. Biomass is another important renewable source, particularly the use of solid municipal waste, the livestock and the wood waste. Finally, other alternate technique is represented by the fuel cells, though it is not properly renewable. However, considering its modular and low environmental impact characteristics, it can get a wide commercial development in the next decade. [Espanol] Existen diversas fuentes nuevas de energia para generar electricidad.

    By 2050, population, society and economic structures will have changed several times. The long and short-term goals and objectives concerning our built environment are mutually contradictory. Determining objectives or creating scenarios for the future built environment is fruitless. We should approach the development of the built environment from the perspective of change and improve the flexibility and adaptability of the built environment. For the users, a built environment meeting their basic needs is part of sustainable development. Identified short-range renovation needs include eliminating damp and mould problems, improving energy and eco-efficiency, removing obstacles to mobility and adapting buildings to accommodate the needs of the elderly. Vacated areas and buildings should be recycled and offered a new life supporting a sense of community and service production. Improved energy efficiency reduces greenhouse gas emissions. Instead of renovating individual buildings, renovation of the entire area is recommended. Sustainability in construction translates into favouring recycling and renewable materials and building-specific energy systems using renewable and/or low-emission resources. It is recommended that renovations to improve energy efficiency are scheduled to coincide with other maintenance/ renovations so as to reduce costs. In renovation construction, the role of service improvement is more important than products. Improved services help to identify a solution that fulfils several customer needs, meets financial limitations and can be implemented efficiently. Companies are advised to view renovation construction as an innovative market segment entitled to its own service portfolio. Truths about new building should be discarded and new services developed based on recent study results and new technologies. (orig.)

  14. Actual heating energy savings in thermally renovated Dutch dwellings

    International Nuclear Information System (INIS)

    Majcen, Daša; Itard, Laure; Visscher, Henk

    2016-01-01

    The register of the Dutch social housing stock was analysed, containing 300.000 dwellings, renovated between 2010 and 2013. The main objective was twofold: to evaluate the performance gap in these dwellings before and after the renovation and to establish what renovation measures achieve the highest reduction of consumption, particularly in practice (actual savings). The results showed large performance gaps in dwellings with low R and high U values, local heating systems, changes from a non-condensing into a condensing boiler and upgrades to a natural ventilation system. Regarding the actual effectiveness of renovation measures, replacement of old gas boilers with more efficient ones yields the highest energy reduction, followed by deep improvements of windows. Installing mechanical ventilation yields a small reduction compared to other measures, but still much larger than theoretically expected. The paper shows once more that the calculation method currently in use cannot be considered accurate if compared to actual consumption. The study demonstrated that unrealistic theoretical efficiencies of heating systems and insulation values are causing a part of the performance gap. Nowadays, large datasets of buildings thermal performance and actual consumption offer an opportunity to improve these misconceptions. - Highlights: • Performance gap is lower in more efficient buildings. • Replacements of gas boilers – the most energy reduction among renovation measures. • Replacing the ventilation system yields a much larger reduction than expected. • How well are the standard values of the calculation methods defined? • Provide large public building performance databases including actual use data.

    This study was conducted over 30 weeks on a hospital floor undergoing partial renovation. Some patients housed on the floor were immunosuppressed, including bone marrow transplant recipients. The construction zone was placed under negative pressure and was separated from patient rooms by existing hospital walls and via erection of a temporary barrier. Other control measures minimized patient exposure to airborne materials. Air sampling was done for 3 weeks prior to construction, 24 weeks during construction, and 3 weeks after renovation was completed. Airborne particulate concentrations, total spore counts, particle size, and fungal species were assessed. At the beginning of the renovation there were increases in airborne particulates (from 0.2 to 2.0 mg/m3) and fungal spores (from 3.5 to 350 colony forming units (CFU/m3), but only in the construction zone. Throughout the remainder of the renovation, particulate and fungal spore levels fluctuated inside the construction zone but remained close to baseline values in the patient area. When renovation was completed, particulates and spore counts inside the construction zone decreased to preconstruction levels. The primary fungus isolated from air samples was Penicillium. This study demonstrated that control measures were effective in reducing exposures of hospitalized patients to airborne particulates and spores and in reducing the increased risk of aspergillosis and other fungal infections associated with hospital construction projects. The data from this study may be useful in establishing exposure guidelines for other health care settings.

    Heating of dwellings represents a major policy challenge for the transition to a low carbon society. In Denmark, heating of dwellings represents about 25% of the total Danish final energy consumption and about 13% of the total CO2 emission. The majority of this is related to heating of older dwellings, and as the rate of replacement is low, the main potential for energy saving is to improve the energy efficiency of the existing dwelling stock through energy renovation. This paper provides an analysis of Danish experiences with energy labels (also known as the Energy Performance Certificate, EPC), which indicate the energy efficiency of buildings and include recommendations for improvements. The aim of the EPC is to motivate homeowners to do energy improvements. In Denmark, energy audit schemes date back to the early 1980s and energy rating of houses (energy labelling) was introduced in 1997. The long history of energy audit schemes and energy labelling makes Denmark an interesting case for the study of the experiences with and impact of this kind of policy measure. With the EU Energy Performance of Buildings Directive (EPBD) from 2002, an energy labelling scheme similar to the Danish scheme introduced in 1997 is now in use in all EU member states. The focus of this paper is on the homeowners' experience and use of the EPC and the key research questions are: How do the homeowners understand and use the EPC? Does the EPC have an influence on home energy renovation practices? The analysis is based on results from a survey of Danish homeowners who have purchased a home with an EPC within recent years. The Danish survey is part of the European project IDEAL EPBD, which was funded by the European Commission under the Intelligent Energy Europe programme and run from 2008 to 2011. The results indicate a rather limited influence of the EPC on Danish homeowners' home energy renovation practices. Also, the results show that even though most homeowners find the label

    When freshwater meets saltwater, for example, where a river flows out into the sea, enormous quantities of energy can be utilised to generate power, through the natural phenomenon of osmosis. Osmotic power is based on the natural phenomenon of osmosis, defined as the transport of water through a semi-permeable membranes, enclosing their cells, and tho produce osmotic power one has to design similar, artificial membranes. In an osmotic power plant we feed freshwater into separate chambers, separated by an artificial membranes. The salt molecules in the seawater then draw the freshwater through the membranes, causing the pressure on the seawater side to increase. This pressure corresponds to a water column of 120 meters or a large waterfall, and can be utilised in a turbine which generated electricity. The idea to generate power through osmosis is originates from the 1970s. At the time, however, the membranes had low efficiency and power price were too low to enable anyone to profitable invest in such a project. many years later, research scientists al SINTEF brought the idea to STAT kraft. The collaboration was initiated in 1997, and the development of a new, renewable energy source was initiated. (Author)

    The Thacher School is in the process of renovating the campus observatory with a new meter class telescope and full automation capabilities for the purpose of scientific research and education. New equipment on site has provided a preliminary site characterization including seeing and V-band sky brightness measurements. These data, along with commissioning data from the MINERVA project (which uses comparable hardware) are used to estimate the capabilities of the observatory once renovation is complete. Our V-band limiting magnitude is expected to be better than 21.3 for a one minute integration time, and we estimate that milli-magnitude precision photometry will be possible for a V=14.5 point source over approximately 5 min timescales. The quick response, autonomous operation, and multi-band photometric capabilities of the renovated observatory will make it a powerful follow-up science facility for exoplanets, eclipsing binaries, near-Earth objects, stellar variability, and supernovae.

    In the transportation sector one of the questions that we should keep on asking on the subject of energy saving is: What objective should be set for reducing the energy consumption (particularly in oil derivatives). Must it be a moderate or a strong measure? In the past years this question was very much related to the oil availability that is a non-renewable resource, nevertheless, with the elapsing of time it can be said that the available oil resources are still very large, the problem is now in function of the energy prices in the mid term and this is what will take us to establish a type of policy for the reduction of the use of fuels in transportation. The purpose of this paper, is to have the support of the transportation users informing and persuading them on the need of reducing the fuel consumption rationalizing its utilization, to ensure in our cities a relatively fluid circulation, a breathable air, a better landscape and a protection to the urban sites. Although these proposals belong in a direct way to our governments, the base of their definition will be the perspectives for the country`s development, the amount of oil reserves, the international situation and the technological advances.

    Critical to the Hospital's rebuilding efforts have been its public partners at the federal, state, and local government levels who have made a major financial commitment to renovating the Hospital's research infrastructure. To date, the Hospital for Special Surgery (HSS) has been awarded a total of nearly $8.5 million to create and equip new, state-of-the-art laboratories for scientific investigations. The modernization of the Hospital's research facilities was jump-started in 1998 with a $950,000 seed grant from the National Institutes of Health (NIH) to renovate laboratories for immunology research in the Caspary Research Building. Coupled with a matching $5.5 million commitment from HSS, this infusion of NIH funding laid the groundwork for an overhaul of all of the Hospital's research space.

    This memorandum identifies the more significant environmental issues that would be associated with renovation and startup of R Reactor to meet future demands for nuclear weapon materials. Some key environmental issues identified are: potential occupational radiation exposures associated with repairing the leaks in the reactor nozzles and thermal shield tanks and with renovating the disassembly basin facilities; the impacts of constructing additional cooling water pumping capacity; the effect of increased pumping on impingement and entrainment at the pump houses; thermal effects on the R Canal-precooler pond-Par Pond ecosystem from increased discharge of cooling water; and effects of increased water flow in Lower Three Runs Creek on biota and on cesium-137 remobilization

    Proper pasture management is important in promoting optimal forage growth and reducing runoff and nutrient loss. Pasture renovation is a management tool that improves aeration by mechanically creating holes or pockets within the soil. Pasture renovation was performed before manure application (poultry litter or swine slurry) on different pasture soils and rainfall simulations were conducted to identify the effects of pasture renovation on nutrient runoff and forage growth. Renovation of small plots resulted in significant and beneficial hydrological changes. During the first rainfall simulation, runoff volumes were 45 to 74% lower for seven out of eight renovated treatments, and infiltration rates increased by 3 to 87% for all renovated treatments as compared with nonrenovated treatments. Renovation of pasture soils fertilized with poultry litter led to significant reductions in dissolved reactive P (DRP) (74-87%), total P (TP) (76-85%), and total nitrogen (TN) (72-80%) loads in two of the three soils studied during the first rainfall simulation. Renovation did not result in any significant differences in forage yields. Overall, beneficial impacts of renovation lasted up to 3 mo, the most critical period for nutrient runoff following manure application. Therefore, renovation could be an important best management practice in these areas.

  16. An integrated urban drainage system model for assessing renovation scheme.

    Science.gov (United States)

    Dong, X; Zeng, S; Chen, J; Zhao, D

    2012-01-01

    Due to sustained economic growth in China over the last three decades, urbanization has been on a rapidly expanding track. In recent years, regional industrial relocations were also accelerated across the country from the east coast to the west inland. These changes have led to a large-scale redesign of urban infrastructures, including the drainage system. To help the reconstructed infrastructures towards a better sustainability, a tool is required for assessing the efficiency and environmental performance of different renovation schemes. This paper developed an integrated dynamic modeling tool, which consisted of three models for describing the sewer, the wastewater treatment plant (WWTP) and the receiving water body respectively. Three auxiliary modules were also incorporated to conceptualize the model, calibrate the simulations, and analyze the results. The developed integrated modeling tool was applied to a case study in Shenzhen City, which is one of the most dynamic cities and facing considerable challenges for environmental degradation. The renovation scheme proposed to improve the environmental performance of Shenzhen City's urban drainage system was modeled and evaluated. The simulation results supplied some suggestions for the further improvement of the renovation scheme.

    The renovation work under way in the CERN Main Building should be completed by June. From the floors to the ceilings, everything has been done to give this historic building a new lease of life.     Taken in the early 60s, this picture illustrates how light maintenance was a challenge for the auditorium in CERN’s main building.   Nobody who has recently had to shimmy between the cables, ladders and toolboxes deposited around the main hall of Building 500 to get to the post office, the bank or Restaurant 1 can be oblivious to the fact that the ground floor of the Main Building has been getting a face-lift. The renovation work, which started with the first-floor concourse in June 2010, should be finished over the next couple of months. The first-floor renovations, now almost complete, set the tone for the rest of the project. The floor and ceiling, both fitted with special acoustic materials for efficient noise damping, have been completely refurbished and the Building ...

  18. On the Testing of Renovations Inside Historical Opera Houses

    Fausti, P.; Prodi, N.

    2002-11-01

    Due to the large number of historical opera houses in Italy, many theatres have been renovated in the past, but still more will undergo major restoration in the near future. Unfortunately in this context, the quality and protection of acoustics is rarely considered as an issue of its own. As a consequence, the renovations are hardly ever accompanied by proper scientific and technical support. In this paper, the acoustical impact of works inside the Teatro Municipale "R.Valli" in Reggio Emilia, including the restoration of the main hall and the construction of a new acoustic shell, will be dealt with. Surveys were held in the theatre before renovation and were repeated with identical procedure and instruments after its completion. By means of a comparative analysis of the architectural project and of acoustical data, the impact of major changes in the theatre can be predicted. It is shown that this approach can help in drafting an operational scheme for safeguarding the acoustics of historical opera houses.

    2014-01-01

    Renovation of the control system of the CERN LHC injectors was initiated in 2007 in the scope of the Injector Controls Architecture (InCA) project. One of its main objectives was to homogenize the controls software across CERN accelerators and reuse as much as possible the existing modern sub-systems, such as the settings management used for the LHC. The project team created a platform that would permit coexistence and intercommunication between old and new components via a dedicated gateway, allowing a progressive replacement of the former. Dealing with a heterogeneous environment, with many diverse and interconnected modules, implemented using different technologies and programming languages, the team had to introduce all the modifications in the smoothest possible way, without causing machine downtime. After a brief description of the system architecture, the paper discusses the technical and non-technical sides of the renovation process such as validation and deployment methodology, operational applicatio...

    Full Text Available Optimised project delivery methods forsocial housing energy renovations European Social Housing Organisations (SHOs are currently facing challenging times. The ageing of their housing stock and the economic crisis, which has affected both their finances and the finances of their tenants, are testing their capacity to stick to their aim of providing decent and affordable housing. Housing renovation projects offer the possibility of upgrading the health and comfort levels of their old housing stock to current standards and improve energy efficiency, and this solution also addresses the fuel poverty problems suffered by some tenants. Unfortunately, the limited financial capacity of SHOs is hampering the scale of housing renovation projects and the energy savings achieved.  At the same time, the renovation of the existing housing stock is seen as one of the most promising alternative routes to achieving the ambitious CO2 emissions reduction targets set by European authorities – namely, to reduce EU CO2 emissions to 20% below their 1990 levels by 2020. The synergy between European targets and the aims of SHOs has been addressed by the energy policies of the member states, which focus on the potential energy savings achievable by renovating social housing. In fact, the European initiatives have prioritised energy savings in social housing renovations to such an extent that these are referred to as ‘energy renovations’. Energy renovation is therefore a renovation project with higher energy savings target than a regular renovation project. In total, European SHOs own 21.5 million dwellings representing around 9.4% of the total housing stock. Each SHO owns a large number of dwellings, which means there are fewer people to convince of the need to make energy savings through building renovations, maximising the potentially high impact of decisions. Moreover, SHOs are responsible for maintaining and upgrading their properties in order to continue

    2014-12-01

    Full Text Available Um sistema híbrido é aquele que utiliza conjuntamente mais de uma fonte de energia para geração de energia elétrica, sendo que tal opção é feita de modo que uma fonte complemente a eventual falta da outra. Tais sistemas podem ser combinações de uma ou mais formas de geração, podendo ser usados sistemas eólicos, fotovoltaicos, diesel, hídricos, ou outros, sendo a opção do armazenamento energético não obrigatória. Dentre as fontes energéticas utilizadas pelos sistemas híbridos, as que mais se sobressaem são a solar e a eólica, ambas de caráter renovável. O sucesso de sua implantação depende diretamente da confiabilidade da operação ao fornecimento de energia e do custo da energia gerada. O objetivo deste trabalho foi apresentar diversas características de tais sistemas de geração de energia elétrica. Em relação ao dimensionamento do sistema, mostrou-se que é importante a análise de custos e formas de utilização do sistema, bem como fatores elétricos do sistema, tais como perda de carga e vida útil da bateria. Como forma de divulgação e especificação dos componentes de um sistema híbrido de geração de energia elétrica, foi eleito um sistema eólico fotovoltaico localizado na Faculdade de Ciências Agronômicas de Botucatu, o qual possibilitou diversas pesquisas junto ao Núcleo de Energias Alternativas e Renováveis do Laboratório de Energização Rural do Departamento de Engenharia Rural da UNESP, Faculdade Ciências Agronômicas, Campus de Botucatu.

  7. Reflexões sobre hidrelétricas na Amazônia: água, energia e desenvolvimento

    Directory of Open Access Journals (Sweden)

    Bertha Koiffmann Becker

    Full Text Available O ensaio discute a implantação de hidrelétricas na Amazônia a partir das relações entre consumo de água e hidroeletricidade em diferentes escalas de análise, pois, se todos os lugares do planeta são afetados por processos globais, eles não o são de modo homogêneo. À escala global, domina o discurso apocalíptico de escassez crescente da água e do aquecimento global, exigindo a redução de emissões de gases de efeito estufa mediante o uso de energias renováveis e novas tecnologias. Na escala nacional, os problemas do Brasil são, pelo contrário, como gerir a abundância de água com justiça social e territorial, e como sustar a perda de 20% da energia elétrica produzida. Finalmente, é na escala regional - na Amazônia - que emergem os maiores problemas: i o maior paradoxo entre abundância de água e inacessibilidade social ao recurso; ii grande parte das hidrelétricas planejadas para o país será ali construída, com risco dos graves impactos conhecidos; iii a cogitada obrigatoriedade da construção de eclusas em todas as hidrelétricas, proposta pelo setor industrial em benefício da navegabilidade dos rios, deverá propiciar, na verdade, o escoamento de commodities produzidas na região Centro-Oeste. Coloca-se, assim, para a sociedade e para o governo, a questão ética se realmente são necessárias tantas hidrelétricas na Amazônia.

    The renovation or refurbishment is an important point in the life cycle of a building that makes it possible to achieve both environmental and climate protection goals and a higher quality of living of the inhabitants. However, lack of money often leads to a renovation that covers only the basic requirements, whereas measures that are valuable in a long term perspective like energy saving measures are not realised. Energy performance contracting (EPC) is widely used as an instrument to reduce long term operating costs significantly by guaranteed energy savings. An energy service company (ESCo) implements saving technologies, especially in the field of heating, HVAC, lighting and plug loads, and in particular in public buildings. It is the aim of this paper to investigate the possibilities to incorporate construction measures like building envelope insulation into standard energy performance contracting.For this purpose a qualitative survey is presented that was performed among experts and stakeholders in the business: ESCos, building owners and facility managers, representatives of construction companies and financing institutions were interviewed. The focus was on their experiences with such projects, on difficulties that arose or barriers that exist from their point of view and on the chances they perceived. This provides the basis for identifying restraints and supporting factors for the integration of contracting and constructional measures.Three pilot projects that have been renovated in Austria are outlined subsequently. They are evaluated with respect to the contractual network between the project partners, types of guarantees and financing issues. Special emphasis is put on the assignment of tasks and the cash flow between the project partners. Various constellations of trades acted as energy service provider: a general contractor, an energy supply company, a consortium of a builder and a plumber. The projects reveal some differences to the standard energy

    Background Routine renovation of older housing is a risk factor for childhood lead poisoning, but the contribution to children’s blood lead levels is poorly defined for children with lower exposure levels. Methods We examined a prospective cohort of 276 children followed from 6 to 24 months of age. We conducted surveys of renovation activities and residential lead hazards and obtained blood lead level (B-Pb) every six months. We analyzed B-Pb in a repeated measures design using a mixed effects linear model. Results Parent reported interior renovation ranged from 11 to 25% of housing units at the four, 6-month periods. In multivariable analysis, children whose housing underwent interior renovation had a 12% higher mean B-Pb by two years of age compared with children whose housing units were not renovated (p children in non-renovated housing, children whose housing units underwent renovation in the prior month had a 17% higher mean B-Pb at two years of age, whereas children whose housing renovation occurred in the prior 2–6 months had an 8% higher mean B-Pb. We also found an association between higher paint lead loading, measured using an X-ray fluorescence (XRF) based paint lead index, and child B-Pb (p = 0.02); for every 10 mg/cm2 increase in paint lead loading index there was a 7.5% higher mean childhood B-Pb. Conclusions In an analysis of data collected before the recent changes to Environmental Protection Agency’s Lead, Renovation, Repair and Painting Rule, routine interior housing renovation was associated with a modest increase in children’s B-Pb. These results are important for the provision of clinical advice, for housing and public health professionals, and for policymakers. PMID:23981571

    Fuel cells, as totally clean power plants, have many applications in the industry in general, in the transport system, in the electricity generation for domestic consumption and in the communication systems, among others. When developing new forms of generation with renewable energy sources, it must be considered that petroleum will stop in being an available power resource. The interest in the study of the fuel cells has been increased in the last years because it is considered a solution to the supply of distributed energy problem. Therefore, already exist research institutions that are developing work on this technology. A generation of electrical energy system based on fuel cells is a nonlinear system where the control of the variables of the process, such as the temperature of the system and the pressurization of the reactants, are an important aspect for its proper operation, since it influences in the water balance and therefore in the global efficiency of the system. [Spanish] Las celdas de combustible, como fuente de energia totalmente limpia, tienen muchas aplicaciones en la industria en general: en el sistema de transporte, en la generacion de electricidad para consumo domestico y en los sistemas de comunicacion, entre otros.

El interes en el estudio de las celdas de combustible se ha incrementado en los ultimos anos debido a que se le considera una solucion al problema de abasto de energia distribuida. Por lo tanto, ya existen instituciones de investigacion que estan desarrollando trabajos sobre esta tecnologia.

    Vinícius Rückert Roso

    2016-03-01

    Full Text Available Nos esforços globais para a minimização nas emissões de gases do efeito estufa e redução da pegada de carbono, combustíveis renováveis têm sido extensivamente utilizados em substituição aos combustíveis fósseis nos motores de combustão interna. Particularmente para geração de energia elétrica local, motores diesel são os mais utilizados devido à elevada eficiência térmica e a robustez, se comparado a motores de ignição por centelha. Entretanto, estes sistemas apresentam elevados níveis de emissões de óxido de nitrogênio (NOx e material particulado, trazendo sérias consequências para o meio ambiente. Assim, esta pesquisa combina simulação computacional e resultados experimentais da conversão de um motor diesel para a operação com etanol, sendo sua utilização na geração de energia elétrica. Como este combustível renovável é largamente produzido no Brasil utilizando a cana-de-açúcar, acaba por possuir seu custo reduzido em especial próximo à produtores e refinarias. Dados experimentais foram utilizados na validação do modelo computacional unidimensional desenvolvido para a conversão, onde resultados foram analisados para a comparação de ambos combustíveis. Análises econômicas para diferentes condições de carga forneceram informações de custos operacionais em locais próximos às fontes de produção de etanol. Os resultados apontam as vantagens no uso do combustível renovável para a geração de energia elétrica, como o custo reduzido e a menor emissão de NOx ao longo de toda a gama de operação.

    2018-02-01

    This paper elaborates design scenarios for a sports complex in Croatia from a technical and economic aspect. Different energy options are analysed and two are additionally addressed and discussed as the most viable ones. The possibilities of sports complex renovation are shown by properly choosing the appropriate energy concept and thus reducing the overall cost for produced thermal energy by around 33% and reducing the carbon dioxide emission by a factor of 1.8 in comparison with its present state. Finally, this study presents an example of good practice, where renewable energy solutions can be proposed and where it is possible to cover around 70-80% of overall yearly costs from achieved energy savings for the novel plant that is assumed to be financed through a bank loan.

    Full Text Available Enterprise resource planning (ERP systems are often used by companies to automate and enhance their busi- ness processes. The capabilities of ERP systems can be described by best-practice reference models. The purpose of the article is to demonstrate the business process renovation approach with the use of reference models. Although the use of reference models brings many positive effects for business, they are still rarely used in Slovenian small and medium-sized compa- nies. The reasons for this may be found in the reference models themselves as well as in project implementation methodologies. In the article a reference model based on Microsoft Dynamics NAV is suggested. The reference model is designed using upgraded BPMN notation with additional business objects, which help to describe the models in more detail.

    In 2008 a project was started to renovate the CERN's PS Booster (PSB) low-level RF (LLRF). Required LLRF capabilities include frequency program, beam phase, radial and synchronization loops. The new LLRF will control the signals feeding the three RF cavities present in each ring; it will also shape the beam in a dual harmonic mode, operate a bunch splitting and create a longitudinal blow-up. The main benefits of this new LLRF are its full remote and cycle-to-cycle controllability, built-in observation capability and flexibility. The overall aim is to improve the robustness, maintainability and reliability of the PSB operation and to make it compatible with the injection from the future Linac4. This paper outlines the main characteristics of the software and hardware building blocks. Initial beam test results and hints on the main milestones and future work are also given.

  1. Energy savings from housing: Ineffective renovation subsidies vs efficient demolition and reconstruction incentives

    International Nuclear Information System (INIS)

    Dubois, Maarten; Allacker, Karen

    2015-01-01

    Energy savings in the housing sector are key to reduce global greenhouse gas emissions. Policies to incentivize energy savings are however disparate between countries. Taking into account environmental aspects and consumer surplus, the paper uses a stylized economic model to assess the effectiveness and efficiency of three economic instruments: subsidies for renovation, subsidies for demolition and reconstruction projects and subsidies for building new houses on virgin land. The assessment also relates to differentiated value added taxes and other financial incentives such as green loans. In a counter-intuitive way, the model highlights that subsidies for renovations with minor energy gains worsen the overall energy consumption of housing due to the inducement of lock-ins with energy inefficient houses. Structural changes are needed in the use of policy instruments. First, commonly applied support schemes for renovations with minor energy savings should be abolished. Second, scarce public resources should incentivize deep renovation and demolition and reconstruction. Finally, taxes should apply on the use of virgin land to persuade households with a high willingness to pay for a new house, to invest in demolition and reconstruction. - Highlights: • Renovation subsidies worsen overall energy consumption of housing. • Renovation induces a lock-in with energy inefficient houses. • Renovation subsidies should be abolished or structurally reformed. • Policy should incentivize demolition and reconstruction projects. • Building on virgin land should be taxed.

    Energy consumption of buildings accounts for around 20-40% of all energy consumed in advanced countries. Over the last decade, more and more global organizations are investing significant resources to create sustainably built environments, emphasizing sustainable building renovation processes to reduce energy consumption and carbon dioxide emissions. This study develops an integrated decision support system to assess existing office building conditions and to recommend an optimal set of sustainable renovation actions, considering trade-offs between renovation cost, improved building quality, and environmental impacts. A hybrid approach that combines A* graph search algorithm with genetic algorithms (GA) is used to analyze all possible renovation actions and their trade-offs to develop the optimal solution. A two-stage system validation is performed to demonstrate the practical application of the hybrid approach: zero-one goal programming (ZOGP) and genetic algorithms are adopted to validate the effectiveness of the algorithm. A real-world renovation project is introduced to validate differences in energy performance projected for the renovation solution suggested by the system. The results reveal that the proposed hybrid system is more computationally effective than either ZOGP or GA alone. The system's suggested renovation actions would provide substantial energy performance improvements to the real project if implemented. (author)

    Highlights: • The proposed national nZEB target can be cost-effectively achieved in renovations. • Energy saving potential of HVAC systems is significant compared to the building envelope. • Modern renewable energy production technologies are cost-efficient and recommendable. • Improving the indoor climate conditions in deep renovations is recommendable. • Simulation-based optimization method is efficient in building performance analyzes. - Abstract: The paper discusses cost-efficient energy performance renovation measures for typical educational buildings built in the 1960s and 1970s in cold climate regions. The study analyzes the impact of different energy renovation measures on the energy efficiency and economic viability in a Finnish case study educational building located in Lappeenranta University of Technology (LUT) campus area. The main objective of the study was to determine the cost-optimal energy performance renovation measures to meet the proposed national nearly zero-energy building (nZEB) requirements, which are defined according to the primary energy consumption of buildings. The main research method of the study was simulation-based optimization (SBO) analysis, which was used to determine the cost-optimal renovation solutions. The results of the study indicate that the minimum national energy performance requirement of new educational buildings (E_p_r_i_m_a_r_y ⩽ 170 kWh/(m"2,a)) can be cost-effectively achieved in deep renovations of educational buildings. In addition, the proposed national nZEB-targets are also well achievable, while improving the indoor climate (thermal comfort and indoor air quality) conditions significantly at the same time. Cost-effective solutions included renovation of the original ventilation system, a ground source heat pump system with relatively small dimensioning power output, new energy efficient windows and a relatively large area of PV-panels for solar-based electricity production.

    Housing industry in Malaysia is growing rapidly due to the increase in population and the arising of economic level of Malaysian people. Most residential houses are built according to the standard residential design that may lead to house renovation by the buyers after purchasing the house. A method of using Unmanned Aerial Vehicle (UAV) monitoring was used to obtain information of the renovated houses directly on-site at Taman Manis 2, Parit Raja, Batu Pahat. Through comparison of image captured by the UAV with the original house plans, we found out that a total of 160 units out of 336 units of houses undergo a renovation process. Surprisingly, 41 units have been renovated illegally which has 40% to 96% of renovation rate. The acquired data were analyzed and can be concluded that the method of using UAVs to obtain information is highly recommended. The study is expected to help Municipal Council to detect improper & illegal renovation by the residents in a residential area.

    Constructed soil filter (CSF) also known as Soil Biotechnology (SBT) is a process for water renovation which makes use of formulated media with culture of soil macro- and microorganisms. CSF combines sedimentation, infiltration and biodegradation processes to remove oxidizable organics and inorganics of wastewater in a single facility. Operating experience shows hydraulic loading in the range of 0.05-0.25 m(3)/m(2) h and organic loading up to 200-680 g/m(2) d. The results show increase in dissolved oxygen levels, COD removal (from 352 mg/l to 20 mg/l); BOD removal (from 211 mg/l to 7.0 mg/l); suspended solids removal (from 293 mg/l to 16 mg/l); turbidity reduction (from 145 NTU to 5.3 NTU); iron (from 5 mg/l to 0.3 mg/l); arsenic (from 500 microg/l to 10 microg/l); total coliform and fecal coliform removal (from 145 x 10(5) to 55 CFU/100 mL and 150 x 10(8) to 110 CFU/100 mL respectively), with desired pathogen levels as per WHO standards, i.e. aeration and no odor, fish compatible water quality and evergreen ambience.

  3. A framework for sustainability science: a renovated IPAT identity.

    Learning actors' leverage for change along the journey to sustainability requires quantifying the component forces of environmental impact and integrating them. Population, income, consumers' behavior, and producers' efficiency jointly force impact. Here, we renovate the "IPAT Identity" to identify actors with the forces. Forcing impact I are P for population, A for income as gross domestic product (GDP) per capita, C for intensity of use as a good per GDP, and T for efficiency ratios as impact per good. In the "ImPACT Identity," parents modify P, workers modify A, consumers modify C, and producers modify T. Because annual percentage changes in component forces add to a change in national impact, actors' leverage is reflected transparently in consistent units of annual percentage changes that can be compared from force to force. Examples from energy and food, farming and manufacturing, and steel and water show that declining C, called dematerialization, can temper the sustainability challenge of growth (P x A), and that innovation or efficient technology that lowers T can counter rising consumption (P x A x C). Income elasticity can accommodate connections between income and other forces. From rates of change of forces, the identity can forecast impacts. Alternatively, by identifying the necessary change in forces to cause a projected impact, ImPACT can assay the likelihood and practicability of environmental targets and timetables. An annual 2-3% progress in consumption and technology over many decades and sectors provides a benchmark for sustainability.

  4. Renovation of food-processing wastewater by a Riparian wetland

    1995-01-01

    Treated wastewater from a food-processing plant, together with intermittent outflow from a hypereutrophic pond, were discharged over a 20-year period to a cattail-dominated wetland and hence to a small stream. Organics and nutriet levels in the effluent were comparable to levels in domestic wastewater. Fifteen variables were monitored upstream and downstream from the plant over 18 months. Means for most variables were slightly higher downstream, but differences between stations were not statistically significant. Wetland processing of nitrogen was markedly affected by a change from drought to flood conditions. After accounting for dilution, the overall effect of the wetland on the effluent was to reduce biological oxygen demand 43.7%, ammonia N 46.3%, nitrate/nitrite N 17.4%, and conductivity 15.6%. However, total suspended solids were increased 41.4%, total organic nitrogen 28.8%, and total phosphorus 24.7%. It was concluded that the wetland effectively renovated the effluent but the removal efficiency would be improved if the effluent were pretreated to reduce phosphorus and dispersed to increase residence time in the wetland.

  12. Lowell Observatory's 24-inch Clark Refractor: Its History and Renovation

    Schindler, Kevin; Nye, Ralph; Rosenthal, Peter

    2016-01-01

    In 1895, Percival Lowell hired eminent telescope maker Alvan G. Clark to build a 24-inch refractor. Lowell intended the telescope intitally for observing Mars in support of his controversial theories about life on that planet. Clark finished the telescope within a year and at a cost of $20,000. Lowell and his staff of assistants and astronomers began observing through it on July 23, 1896, setting off a long and productive career for the telescope.While Lowell's Mars studies dominated early work with the Clark, V.M. Slipher by the 1910s was using it to observe planetary rotations and atmospheric compositions. He soon revolutionized spectroscopic studies, gathering excruciatingly long spectra - some in excess of 40 hours - of the so-called white nebula and determining startling radial velocities, evidence of an expanding universe. In the 1960s, scientists and artists teamed up on the Clark and created detailed lunar maps in support of the Apollo program.In recent decades, the Clark has played a central role in the education programs at Lowell, with general public audiences, students, and private groups all taking advantage of this unique resource.With this nearly 120 years of contant use, the Clark had been wearing down in recent years. The telescope was becoming more difficult to move, old electrical wiring in the dome was a fire hazard, and many of the telescope's parts needed to be repaired or replaced.In 2013, Lowell Observatory began a fundraising campaign, collecting $291,000 to cover the cost of dome and telescope renovation. Workers removed the entire telescope mount and tube assembly from the dome, examining every part from tube sections to individuals screws. They also stabilized the dome, adding a water vapor barrier and new outer wall while reinforcing the upper dome. The project lasted from January, 2014 through August, 2015. The facility reopened for daytime tours in September, 2015 and evening viewing the following month.

  13. Carbon balance of renovated grasslands: input- or output-driven?

    2015-04-01

    Temperate grasslands constitute over 30% of the Earth's naturally-occurring biomes and make an important contribution towards the partial mitigation of anthropogenic greenhouse gas emissions by terrestrial ecosystems. In permanent temperate grasslands, biomass production and sward quality can deteriorate over time and periodic renovation activities, involving soil tillage and reseeding, are commonly carried out to halt this decline. Long-term cultivation of agricultural land has been associated with soil aggregate degradation and reduced soil carbon storage. However, the impact of these single tillage disturbances on C cycling in grasslands is less clear. This study evaluated gaseous and dissolved organic carbon (DOC) losses following a single tillage event by subjecting grassland lysimeters with contrasting soil drainage characteristics to simulated conventional inversion or minimum tillage. Field-scale CO2 emissions after conventional tillage were also quantified and empirically modelled over short- and medium-term timeframes to delineate the ecosystem response to environmental variables. Soil moisture was the limiting determinant of ecosystem carbon release following conventional tillage. Freshly-tilled soils were associated with reduced water retention and increased sensitivity to soil moisture, which was particularly pronounced following rewetting events. Significantly elevated but ephemeral CO2 effluxes were detected in the hours following inversion ploughing, however tillage disturbance did not generate significantly enhanced C emission rates in the medium term. Equally, DOC losses were not significantly amplified by conventional tillage compared with conservative minimum tillage and were predominantly controlled by soil drainage across tillage regimes. Our results suggest that a net ecosystem source of 120 to 210 g C m-2 over an approximately two-month period was most likely a consequence of reduced productivity and C input rather than enhanced soil CO2

    Despite of the rising in the fuel and its by-products, alternative energy sources have not vet developed specially in small plants for local generation. Thermal solar energy and biomass could provide most of the thermal energy required in the residential and commercial buildings and provide new solutions such as solar cooling, but people usually distrust because of its difficulties to be operated by no expert staff. In this situation remote operation systems are necessary to increase the number of installations and increase the sales. In the same way these kinds of systems could increase the technology exports to development countries where alternative energy sources can provide energy generation solutions that would improve the quality of life.

    The present work undertakes the study of the regional integration of renewable energies from a territorial perspective. It is structural in two parts, one dealing with power planning and regional integration, and the other with the aspects connected to the application of GIS in this field. Concerning power planning, two questions are pointed out: the role of RES in the estimation of the demand in the main power scenarios, and the existing relations between power policies and territorial planning. Referring to the regional integration of renewable energies a description, fundamentally geographic, of the main sources and their main advantages and drawbacks is tackled, followed by the study of the environmental and social aspects and a revision of the role of the institutions (both Spanish and European) in the overcoming of the drawbacks. In the second part of the work the state of the knowledge of the application of GIS to this field is approached. The study is structured in three blocks of applications: decision support,grid connected and isolated systems. The work continues with an in-depth analysis of two applications developed by the author. The first one is centred in the analysis of locations for hybrid systems (solar biomass) in distributed generation. The second one analyses the territorial competitiveness of different systems for rural electrification. In this last one, a method of spatial sensitivity analysis is also developed for the control of the application. Therefore this work tries to show that is is important to take into account the territorial aspects and also to incorporate tools of geographic technology to improve the regional integration of renewable energies.

This portfolio should be enough and reliable all the time, guarantee the security of supply, protect the environment and give competitive prices. All these features are to a great extent met by nuclear and renewable technologies and therefore they should play an important role on world and national energy supply. (Author)

The objective of this project is to analyse, evaluate and improve the GIS methodologies for application in RE and how GIS can aid in the evaluation and simulation of influence of technical, socio economical and geographical parameters. This project begin with the review of SOLARGIS methodology. SOLARGIS was developed by an european research team (included CIEMAT) in the frame of JOULE II Programme. In the first place this report described the state of the art in the application of GIS to Renewable Energies. In second place, the SOLARGIS review tasks and the application of this new product to Lorca (Murcia Region in Spain). Finally, the report describes the methodology for the spatial sensibility analysis. (Author) 24 refs.

    What factors increase the chance that residents/owners in housing cooperatives agree on sustainable energy efficient renovation? Based on 30 qualitative interviews with professional advisors in cooperative housing associations and chairman/board and residents in three chosen case studies, an analysis of opportunities and barriers for making a common decision on renovation is performed. Success criteria and barriers are found on the societal level as well as on the organizational/individual level. The barriers and success criteria identified on the societal level are: knowledge level on energy-efficient renovation among relevant actors, owner structure of the housing cooperative, and existing regulations and incentives. On the organizational and individual level, the following categories influencing renovation processes were identified: the time frame and organization of the process, understanding the residents' needs, economy, the information given, and the existence of available exemplary projects and role models. Based on the results of the study, ten guidelines that contribute to more successful decision making processes and increase the chances of sustainable energy efficient renovation in housing cooperatives are presented.

    This study attempts to give a summarised vision of the concept of externally in energy production, the social and economic usefulness of its evaluation and consideration as support to the political decision-marking in environmental regulation matters, technologies selection of new plants, priorities establishment on energy plans, etc. More relevant environmental externalities are described, as are the effects on the health, ecosystems, materials and climate, as well as some of the socioeconomic externalities such as the employment, increase of the GDP and the reduction and depletion of energy resources. Different methodologies used during the last years have been reviewed as well as the principals results obtained in the most relevant studies accomplished internationally on this topic. Special mention has deserved the European study National Implementation of the ExternE Methodology in the EU. Results obtained are represented in Table 2 of this study. Also they are exposed, in a summarised way, the results obtained in the evaluation of environmental externalities of the Spanish electrical system in function of the fuel cycle. In this last case the obtained results are more approximated since have been obtained by extrapolation from the obtained for ten representative plants geographically distributed trough the Peninsula. Finally it has been analysed the influence that the internalization of the external costs of conventional energies can have in the competitiveness and in the market of renewable energy, those which originate less environmental effects and therefore produce much smaller external costs. The mechanisms of internalization and the consideration on the convenience or not of their incorporation in the price of energy have been also discussed. (Author) 30 refs.

    Mosque, for Muslim, is not only a place for daily worshipping, however as a center of culture as well. It is an important and valuable building to be well managed. For a responsible department or institution (such as Religion or Plan Department in Indonesia), to practically manage a lot of mosques is not simple task to handle. The challenge is in relation to data number and characteristic problems tackled. Specifically for renovating and rehabilitating the damaged mosques, a decision to determine the first damaged mosque priority to be renovated and rehabilitated is problematic. Through two types of optimization method, simulated-annealing and hill-climbing, a decision support model for mosque renovation and rehabilitation was systematically constructed. The method fuzzy-logic was also operated to establish the priority of eleven selected parameters. The constructed model is able to simulate an efficiency comparison between two optimization methods used and suggest the most objective decision coming from 196 generated alternatives.

    The presented study is divided into two main issues for wind energy generation: the economical scope, and the environment. A comparison from different perspectives is made between both costs. The study is focused in the Mexico central region called Bajio, where the wind data is obtained. The usage of different types of wind turbines is planned to generate electricity, and a comparison is made between them in different aspects. An invest of 20 years is expected for this equip. While comparing the costs, the estimated by emissions of CO{sup 2} by kW/h generated (environmental cost), with these cost it is showed the quantities of CO{sup 2} that can be stopped of emitting to the atmosphere by the use of fossil fuels. The data encourages the use of renewable energy in relation with the wind potential in the region. This is how the presented study shows the options of decision making to implement and viability of the usage of wind turbines for the production of electric energy under the wind conditions provided by the Bajio region.

    Captive African (Loxodonta africana) and Asian (Elephas maximus) elephants can experience foot pathologies and arthritis. As a preventative measure against these pathologies and to alleviate the potential discomfort due to concrete substrates, some zoological institutions have renovated elephant housing to increase the amount of natural or shock-absorbent substrates. The objective of this study was to compare behavioral (diurnal and nocturnal) and glucorticoid (e.g., serum cortisol) responses of three female African elephants before, during, and after renovation to their indoor housing floor to assess whether renovations had short-term effects on the elephants’ behavior and stress physiology. Behavioral data were collected using scan-sampling methods, and activity budgets were constructed for each of the three elephants. In addition, the duration of all lying rest activities were recorded. Weekly serum cortisol concentrations were determined with enzyme immunoassay (EIA). Overall, eating was the most prevalent behavior exhibited outdoors during the day, while resting (either in a lying or standing position) were most common during the indoor, nocturnal periods. Although variation existed among the three elephants, all three females spent significantly more time walking and less time eating during the day after the completion of the renovations. The extent to which the three elephants exhibited nocturnal lying rest behavior varied among the elephants, with the oldest elephant exhibiting the least amount (an average of 13.2 ± 2.8% of the nightly behavioral scans) compared to the two younger elephants (an average of 34.5 ± 2.1% and 56.6 ± 2.8% of the nightly behavioral scans). There was a significant increase in lying rest behavior for one elephant and standing rest for a second elephant following renovations. Baseline cortisol concentrations prior to renovations were 3.0 ± 0.4 ng/ml, 4.5 ± 0.5 ng/ml, and 4.9 ± 0.5 ng/ml for the three elephants. Cortisol

    Highlights: • Energy saving potential in historic wooden apartment buildings is up to 63%. • In historic wooden apartment buildings an economically viable energy saving level is 50%. • The largest energy saving potential lies in heat source and building service systems. • Of the building structures, insulation of the external wall has the highest potential. • New heating and ventilation systems must be installed to fulfill regulations limits. - Abstract: Buildings represent the largest sector of primary energy consumption and play a major role in saving energy and reducing greenhouse gas emissions. Our analysis of energy consumption and potential energy savings is based on field measurements, computer simulations and economic calculations. The average primary energy consumption (PE) of wooden apartment buildings was 331 kW h/(m 2 a) 83% higher than the limit 180 kW h/(m 2 a) set in national regulations for apartment buildings subject to major renovation. The studied buildings represent a high potential for energy savings. The renovation packages were compiled using different insulation measures, HVAC solutions and energy sources to achieve a 20–65% reduction of primary energy. For historic buildings, the renovation solutions that concentrate on the building envelope can be problematic due to the need to preserve cultural and architectural values. Our calculation results indicate that the cost optimal PE level is around 250 kW h/(m 2 a) and the point at which renovation packages recover expenses is around a PE level of 170 kW h/(m 2 a). In terms of the architectural appearance the point at which renovation packages recover expenses is around a PE level of 210 kW h/(m 2 a). We propose to set a different PE limit for historic wooden apartment buildings with an architectural appearance worth preserving

    The study estimates the feasible energy savings potential in the 2010 building stock by 2050. The focus is on energy-saving measures related to renovation of residential and service buildings. The calculations were done by building types and age groups using the EKOREM calculation model. The calculations indicate the building types and structural elements where potential for savings exists. The study did not consider energy-saving measures related to changes in heating systems, electrical equipment, property maintenance or use habits. The study disproved the common belief that considerably more energy savings could be achieved faster by focussing on the existing building stock instead of new construction. That is mainly due the fact that it generally pays to implement structural energy-saving measures only when the targeted elements also require other significant repairs besides energy-efficiency improvements. Thus, energy renovations cannot be speeded up very much. The clearest exception are the extra insulations added to roof assemblies that are easy to implement. Attempts to save more energy in the building stock than can be achieved at a small additional cost in connection with needed renovations may multiply costs, and the saving in energy costs will not necessarily cover the additional investments. The efficiency of energy-saving measures can be affected by recommending or ordering use of more energy efficient windows, thicker extra insulations or more efficient ventilation heat recovery systems than the standard solution selected in connection with renovations. The goal of preserving the characteristics of buildings of cultural-historical or architectural value and the typical solutions and materials used in all buildings of a certain period limit the repair and renovation of structural elements. In the case of these buildings, improvement of energy efficiency can be considered in connection with the planning of renovations and the buildings' use and

    Full Text Available Abstract Background Children in poor and minority neighborhoods often lack adequate environmental support for healthy physical development and community interventions designed to improve physical activity resources serve as an important approach to addressing obesity. In Denver, the Learning Landscapes (LL program has constructed over 98 culturally-tailored schoolyard play spaces at elementary schools with the goal to encourage utilization of play spaces and physical activity. In spite of enthusiasm about such projects to improve urban environments, little work has evaluated their impact or success in achieving their stated objectives. This study evaluates the impacts of LL construction and recency of renovation on schoolyard utilization and the physical activity rates of children, both during and outside of school, using an observational study design. Methods This study employs a quantitative method for evaluating levels of physical activity of individuals and associated environmental characteristics in play and leisure environments. Schools were selected on the basis of their participation in the LL program, the recency of schoolyard renovation, the size of the school, and the social and demographic characteristics of the school population. Activity in the schoolyards was measured using the System for Observing Play and Leisure Activity (SOPLAY, a validated quantitative method for evaluating levels of physical activity of individuals in play and leisure environments. Trained observers collected measurements before school, during school recess, after school, and on weekends. Overall utilization (the total number of children observed on the grounds and the rate of activity (the percentage of children observed who were physically active were analyzed. Observations were compared using t-tests and the data were stratified by gender for further analysis. In order to assess the impacts of LL renovation, recently-constructed LL schoolyards were

The module will fly as a primary payload on the second Space Shuttle/Mir space station docking mission, STS-74, which is now scheduled for liftoff in the fall of 1995. During the mission, the module will first be attached with the orbiter's robot arm to the Orbiter Docking System (ODS) in the payload bay of the orbiter Atlantis and then be docked with the Mir. When Atlantis undocks from the Mir, it will leave the new docking module permanently attached to the space station for use during future Shuttle Mir docking missions. The new module will simplify future Shuttle linkups with Mir by improving orbiter clearances when it serves as a bridge between the two space vehicles.

    Measuring patient experience is key when assessing quality of care but can be biased: A perceptual bias occurs when renovations of the interior design of a general practitioner (GP) office improves how patients assessed quality of care. The aim was to assess the length of perceptual bias and if it could be reproduced after a second renovation. A GP office with 2 GPs in Switzerland was renovated twice within 3 years. We assessed patient experience at baseline, 2 months and 14 months after the first and 3 months after the second renovation. Each time, we invited a sample of 180 consecutive patients that anonymously graded patient experience in 4 domains: appearance of the office; qualities of medical assistants and GPs; and general satisfaction. We compared crude mean scores per domain from baseline until follow-up. In a multivariate model, we adjusted for patient's age, gender and for how long patients had been their GP. At baseline, patients aged 60.9 (17.7) years, 52% females. After the first renovation, we found a regression to the baseline level of patient experience after 14 months except for appearance of the office (pInterior renovation of a GP office probably causes a perceptual bias for >1 year that improves how patients rate quality of care. This bias could be reproduced after a second renovation strengthening a possible causal relationship. These findings imply to appropriately time measurement of patient experience to at least one year after interior renovation of GP practices to avoid environmental changes influences the estimates when measuring patient experience.

    Aim: This paper presents a two-fold evaluation method determining whether to renovate an existing building or to demolish it and thereafter erect a new building. Scope: The method determines a combination of energy saving measures that have been optimised in regards to the future cost for energy. Subsequently, the method evaluates the cost of undertaking the retrofit measures as compared to the cost of demolishing the existing building and thereafter erecting a new one. Several economically beneficial combinations of energy saving measures can be determined. All of them are a trade-off between investing in retrofit measures and buying renewable energy. The overall cost of the renovation considers the market value of the property, the investment in the renovation, the operational and maintenance costs. A multi-family building is used as an example to clearly illustrate the application of the method from macroeconomic and private financial perspectives. Conclusion: The example shows that the investment cost and future market value of the building are the dominant factors in deciding whether to renovate an existing building or to demolish it and thereafter erect a new building. Additionally, it is concluded in the example that multi-family buildings erected in the period 1850–1930 should be renovated. - highlights: • Development of a method for evaluation of renovation projects. • Determination of an economic optimal combination of various energy saving measures. • The method compared the renovation cost to those for demolishing and building new. • Decision was highly influence by the investment cost and buildings market value. • The results indicate that buildings should be renovated and not demolished

    Full Text Available This paper offers a theoretical reflection on the concept of convergence in the Autonomous Community of Galicia, in Spain. In this geographic area, marked by its respect for journalistic tradition (especially referring to the press and its inertia, it is possible to distinguish two different attitudes (actually conflicting with regard to the convergence phenomenon. Conservation strategies coexist, therefore, (focusing mainly on the business aspect of the convergent phenomenon with renovation strategies (creation of new spaces on the web, great commitment to the possibilities offered by new technologies and social networks. We are presenting an analytical study of the coexistence of these two interpretations of convergence (marketing and technological, respectively in the communication ecosystem of Galicia. We can recognize the beginning of a dialectic tension between the discourses of renovation and conservation which at present coexist in harmony. It is assumed that the information industry in Galicia will eventually choose the path that guarantees the survival of its media.

    To evaluate the effectiveness of Preventing Obesity by Design (POD), a childcare center outdoor renovation intervention. Pre-post intervention evaluation. North Carolina licensed childcare centers (N = 27). Preschool children. Outdoor renovation, teacher training. Behavior mapping, Preschool Outdoor Environment Measurement Scale (POEMS), center director interview. Descriptive statistics, ordinary least squares and logistic regressions calculated to assess levels of association between environmental change, children's physical activity (PA), social behaviors, and environmental quality. Qualitative interview data analyzed to help understand intervention impact. Behavior mapping showed that site layout attributes, such as the form (i.e., "single loop" and "double loop") of pathways (functioning as circulation routes and wheeled toy settings), are associated with higher levels of PA. Teacher interaction was associated with decreased children's PA. Absence of teacher or lack of child/child interaction was associated with increased PA. POEMS assessment of environmental quality was higher after renovation. POEMS domains (Physical Space and Teacher/Caregiver Roles) were positively associated with PA. After renovation, 68% of center directors reported positive changes in children's behavior and 40% mentioned edible plant installations as greatest success. Built environment renovation of childcare center outdoors, including looped pathways installation, coupled with teacher training, may support increased PA. Renovation, including food gardens, may be a key to success for preschool health promotion and support change in childcare policy.

    Highlights: • Energy saving measures can be cost-effective as part of a planned renovation. • Primary energy consumption, non-renewable energy consumption and CO_2 emissions are assessed for different electricity mixes. • EAHP can be a cost-effective and environmentally beneficial complement to district heating. • EAHP has lower LCC and significantly shorter payback time than ventilation with heat recovery. • Low-temperature ventilation radiators improve the COP of the heat pump. - Abstract: Renovation of existing buildings is important in the work toward increased energy efficiency and reduced environmental impact. The present paper treats energy renovation measures for a Swedish district heated multi-family house, evaluated through dynamic simulation. Insulation of roof and façade, better insulating windows and flow-reducing water taps, in combination with different HVAC systems for recovery of heat from exhaust air, were assessed in terms of life cycle cost, discounted payback period, primary energy consumption, CO_2 emissions and non-renewable energy consumption. The HVAC systems were based on the existing district heating substation and included mechanical ventilation with heat recovery and different configurations of exhaust air heat pump. Compared to a renovation without energy saving measures, the combination of new windows, insulation, flow-reducing taps and an exhaust air a heat pump gave up to 24% lower life cycle cost. Adding insulation on roof and façade, the primary energy consumption was reduced by up to 58%, CO_2 emissions up to 65% and non-renewable energy consumption up to 56%. Ventilation with heat recovery also reduced the environmental impact but was not economically profitable in the studied cases. With a margin perspective on electricity consumption, the environmental impact of installing heat pumps or air heat recovery in district heated houses is increased. Low-temperature heating improved the seasonal performance factor of the

    Large scale energy efficient renovation of buildings is one of the most important tools to realize the society's need of a more sustainable building stock. Most Norwegians own their own homes. Therefore private homeowners are a focus group for the government urging to accelerate the dwelling energy efficiency rates. Success factors were identified in the in-depth study of the decision process of eleven homeowners. Large differences in energy use due to the building's condition and the occupants' behavior was encountered in the sample. Only homeowners who were conscious consumers and did not trust expert advice or that had special knowledge due to their professions succeeded in realizing energy efficiency by renovation. Lack of knowledge, bad advice from craftsmen or priority to work that they can do themselves stopped other homeowners from implementing energy efficiency. Increased knowledge on all the gains from energy efficiency, the availability of attractive products and services as well as easy access to reliable advice on the better renovation solutions have a large potential to get more homeowners to make energy efficient choices in the process of renovation. Coordination of more of policy strategies including specific information and incentives are needed to facilitate this. - Highlights: • Private homeowners are a key group to increase the dwelling energy efficiency rates. • The annual energy use varies from 103 kW h/m 2 to 240 kW h/m 2 in similar dwellings. • Homeowners that are conscious consumers or have knowledge succeed in saving energy. • Access to relevant and reliable advice can get homeowners to realize energy savings. • Craftsmen could be mediators between available products and the specific building

    The paper discusses the background and results of research focused on the action of a high-speed water jet on concrete with different qualities. The sufficient and careful removal of degraded concrete layers is very important for the renovation of concrete structures. High-speed water jet technology is one of the most common methods used for removing degraded concrete layers. Different types of high-speed water jets were tested in the experimental part. The classical technology of a single continuous water jet generated with one nozzle was tested as well as the technology of revolving water jets generated by multiple nozzles (used mainly for the renovation of larger areas). A continuous flat water jet and pulsating flat water jet were tested the first time, because the connection of a water jet with the acoustic generator of a pulsating jet offers new possibilities for the use of a water jet (see [1] and [2]). A water jet with such a modification is capable of efficient action and can even be used for cutting solid concrete with a relatively low consumption of energy. A flat pulsating water jet which can be newly used for renovation seems to be a promising technology.

    Full Text Available EU regulations are gradually moving towards policies that reduce energy consumption and its environmental impact. To reach this goal, improving energy efficiency in residential buildings is a key action line. The European Parliament adopted the Near Zero-Energy Building (nZEB as the energy efficiency paradigm through Directive 2010/31/EU, but a common technical and legislative framework for energy renovations is yet to be established. In this paper, the nZEB definition by COHERENO was adopted to evaluate several energy renovation packages in a given building, which is also representative of the Spanish building stock. Global costs are calculated for all of them following EPBD prescriptions. Two economic scenarios are analysed: with entirely private funding and with the current public financial incentives, respectively. The results show the divergence between optimum solutions in terms of costs and of minimum CO2 footprint and maximum energy saving. Moreover, in the absence of enough incentives, some inefficient renovations could achieve a global cost close to the optimal cost. The optimum solution both in terms of energy performance and global costs was carried out and described.

  1. A District Approach to Building Renovation for the Integral Energy Redevelopment of Existing Residential Areas

    2017-05-01

    Full Text Available Building energy renovation quotas are not currently being met due to unfavorable conditions such as complex building regulations, limited investment incentives, historical preservation priorities, and technical limitations. The traditional strategy has been to incrementally lower the energy consumption of the building stock, instead of raising the efficiency of the energy supply through a broader use of renewable sources. This strategy requires an integral redefinition of the approach to energy building renovations. The joint project SWIVT elaborates on a district redevelopment strategy that combines a reduction in the energy demand of existing buildings and their physical interconnection within a local micro-grid and heating network. The district is equipped with energy generation and distribution technologies as well as hybrid thermal and electrical energy storage systems, steered by an optimizing energy management controller. This strategy is explored through three scenarios designed for an existing residential area in Darmstadt, Germany, and benchmarked against measured data. Presented findings show that a total primary energy balance at least 30% lower than that of a standard building renovation can be achieved by a cluster of buildings with different thermal qualities and connected energy generation, conversion, and storage systems, with only minimal physical intervention to existing buildings.

    The article considers a new initiative of the regional authorities of updating the housing stock designated as the renovation of housing. Its main aspects are analyzed, including the nature of program, economic efficiency of its implementation due to high-rise construction and the regulatory and legislative framework, the procedure for implementing the program, and the time frame for its implementation. The role of the program for regions in which high depreciation of the housing stock is combined with a limited number of sites for a new housing construction is disclosed. The high-rise construction in the renovation program is presented as a variant of a successful solution not only of the tasks of renovating the housing stock, but also of filling the regional budget. The social and economic orientation of the high-rise construction and the involvement of residents in the process of making town-planning decisions in the field of high-rise construction at all stages of implementing the program are shown.

  3. A two-factor method for appraising building renovation and energy efficiency improvement projects

    2007-01-01

    The renovation of residential buildings usually involves a variety of measures aiming at reducing energy and building maintenance bills, increasing safety and market value, and improving comfort and aesthetics. A significant number of project appraisal methods in current use-such as calculations of payback time, net present value, internal rate of return or cost of conserved energy (CCE)-only quantify energy efficiency gains. These approaches are relatively easy to use, but offer a distorted view of complex modernization projects. On the other hand, various methods using multiple criteria take a much wider perspective but are usually time-consuming, based on sometimes uncertain assumptions and require sophisticated tools. A 'two-factor' appraisal method offers a compromise between these two approaches. The main idea of the method is to separate investments into those related to energy efficiency improvements, and those related to building renovation. Costs and benefits of complex measures, which both influence energy consumption and improve building constructions, are separated by using a building rehabilitation coefficient. The CCE is used for the appraisal of energy efficiency investments, while investments in building renovation are appraised using standard tools for the assessment of investments in maintenance, repair and rehabilitation

    Full Text Available Sustainable urban renovation is characterized by multiple factors (e.g., technical, socio-economic, environmental and ethical perspectives, different spatial scales and a number of administrative structures that should address the evaluation of alternative scenarios or solutions. This defines a complex decision problem that includes different stakeholders where several aspects need to be considered simultaneously. In spite of the knowledge and experiences during the recent years, there is a need of methods that lead the decision-making processes. In response, a methodology based on a KPI-driven approach for urban renovation at district level is proposed in the European Smart City project CITyFiED. The methodology is a procedure with the energy efficiency as main pillar and the local authorities as client. It is composed of seven phases that ensures an effective dialogue among all the stakeholders, aiming to understand the objectives and needs of the city to deliver a set of customized Strategies for Sustainable Urban Renovation. In order to provide guidance and quantitative criteria, three levels of indicators are integrated into the approach: City Level Indicators (L1 at city & district level, Project Level KPIs (L2, and Impact Assessment Indicators at city level (L3.

    The landlord/tenant dilemma arises when the interests of landlords and tenants misalign and is one of the greatest barriers hindering the development of sustainable renovation of residential buildings in Europe. The aim of this research is to investigate how regulatory changes and contractual solutions can help solve the landlord/tenant dilemma in relation to sustainable renovation of residential buildings, and how the general awareness of sustainable renovation can be increased. Particular focus is on whether tools like energy performance contracting and energy labeling can help solve the landlord/tenant dilemma. The research was done in relation to the specific situation in Denmark, but theory, information and experiences from other countries were included. The results show that there are plenty of opportunities to overcome the landlord/tenant dilemma, but principal/agent problems can only be overcome with a package solution. In the Danish national context the package solution must consist of legislative changes, financial incentives and better dissemination of information. Therefore, an array of different tools must be integrated and used in cooperation to overcome the dilemma. - Highlights: • There are plenty of opportunities to overcome the landlord/tenant dilemma. • The principal/agent problems can only be overcome with a package solution. • An array of different tools must be integrated and used in cooperation. • Legislative changes, financial incentives and better dissemination of information

In the same way, in Chapter 4 a methodology for the optimization of the electrical grids in low tension is proposed, standing out some errors that are commonly committed in the design of these types of networks, doing recommendations to correct them with low cost investments. Because of the importance in the design of medium tension lines, in Chapter 3 the set of economic conductors for 23 kV was determined for urban and rural areas, system type A (3F-4H, 2F-3H, 1F-2H), by means of the Modified Method. With this information we will be able to select the conductor that offers the best economy in the time, in each extension of the network. In Chapter 5 the proposed methodology in the planning of the electrical system of distribution of the Zapotlan Zone was applied, as much in substations as in the high and medium tension network. In this chapter analyses of optimization of the network were performed, capacitor banks application, attention to the incremental demand, power losses, contingencies by fault and reliability of the provision.

    Renewable energy technologies, as wind turbines, have had a remarkable penetration in power systems worldwide, causing that actual power grids became dependent and vulnerable to the variability of the energy generated by this type of resource. In that sense, power converters provide a crucial function in the performance of the overall electrical system when they are used as links between this type of generators and the power system. In this paper, a matrix converter is proposed as link device, to cope with distorted and variable voltages as the ones found in wind turbines operation where generated voltages are directly dependent on wind's speed. An analysis of its main functional characteristics when it operates subject to distorted input-voltage condition, in order to synthesize a set of output voltages with constant magnitude and frequency and without harmonic distortion, is presented. Numerical simulations and experimental results from a laboratory-scale prototype are presented to validate the converter performance.

    The renovation of a building will certainly affect the quality of air in the vicinity of where associated activities were undertaken, this includes the quality of air inside the building. Indoor air pollutants such as particulate matter, heavy metals, and fine fibers are likely to be emitted during renovation work. This study was conducted to determine the concentration of heavy metals, asbestos and suspended particulates in the Biology Building, at the Universiti Kebangsaan, Malaysia (UKM). Renovation activities were carried out widely in the laboratories which were located in this building. A low-volume sampler was used to collect suspended particulate matter of a diameter size less than 10 μm (PM₁₀) and an air sampling pump, fitted with a cellulose ester membrane filter, were used for asbestos sampling. Dust was collected using a small brush and scope. The concentration of heavy metals was determined through the use of inductively coupled plasma-mass spectroscopy and the fibers were counted through a phase contrast microscope. The concentrations of PM₁₀ recorded in the building during renovation action (ranging from 166 to 542 μg m⁻³) were higher than the value set by the Department of Safety and Health for respirable dust (150 μg m⁻³). Additionally, they were higher than the value of PM₁₀ recorded in indoor environments from other studies. The composition of heavy metals in PM₁₀ and indoor dust were found to be dominated by Zn and results also showed that the concentration of heavy metals in indoor dust and PM₁₀ in this study was higher than levels recorded in other similar studies. The asbestos concentration was 0.0038 ± 0.0011 fibers/cc. This was lower than the value set by the Malaysian Department of Occupational, Safety and Health (DOSH) regulations of 0.1 fibers/cc, but higher than the background value usually recorded in indoor environments. This study strongly suggests that renovation issues need to be considered seriously

    The Green Deal is a major new energy policy designed to support the diffusion of energy efficiency measures in UK homes. This paper provides one of the first empirical examinations of the Green Deal′s success in influencing homeowners’ renovation decisions. Using a repeated measures design in which households were questioned before and after the Green Deal′s launch in January 2013, we assess the policy′s success in raising awareness of energy efficiency. In particular, we test the effectiveness of the Green Deal′s positioning to overcome barriers to renovation among homeowners already interested in or considering energy efficiency measures. Using the innovation decision process (Rogers, 2003) as a conceptual framing of the renovation decision process, we examine whether new information on energy efficiency provided by the Green Deal strengthened intentions and its antecedents. We find that (1) energy efficiency is of potential appeal to all renovators regardless of their attitudes about energy efficiency, (2) energy efficiency opportunities need to be identified in the early stages of renovation when homeowners are thinking about ways to improve their home, and (3) homeowners’ intentions towards energy efficiency are weakened by uncertainty about financial benefits, helping to explain the relatively slow uptake of the Green Deal to-date. - Highlights: • Examines the impact of a major new energy policy, the Green Deal, on intentions towards energy efficiency. • 502 households questioned four months prior to, and seven months after the launch. • Renovating itself is mechanism through which households engage with the Green Deal. • Strengthening beliefs in energy savings accelerates intentions to renovate energy efficiently

    Green eco-friendly housing includes approaches to reduce indoor air pollutant sources and to increase energy efficiency. Although sealing/tightening buildings can save energy and reduce the penetration of outdoor pollutants, an adverse outcome can be increased buildup of pollutants with indoor sources. The objective of this study was to determine the differences in the indoor air quality (IAQ) between green and non-green homes in low-income housing complexes. In one housing complex, apartments were renovated using green principles (n = 28). Home visits were conducted immediately after the renovation, and subsequently at 6 months and at 12 months following the renovation. Of these homes, eight homes had pre-renovation home visits; this allowed pre- and post-renovation comparisons within the same homes. Parallel visits were conducted in non-green (control) apartments (n = 14) in a nearby low-income housing complex. The IAQ assessments included PM_2_._5, black carbon, ultrafine particles, sulfur, total volatile organic compounds (VOCs), formaldehyde, and air exchange rate. Data were analyzed using linear mixed-effects models. None of the indoor pollutant concentrations were significantly different between green and non-green homes. However, we found differences when comparing the concentrations before and after renovation. Measured immediately after renovation, indoor black carbon concentrations were significantly lower averaging 682 ng/m"3 in post-renovation vs. 2364 ng/m"3 in pre-renovation home visits (p = 0.01). In contrast, formaldehyde concentrations were significantly higher in post-renovated (0.03 ppm) than in pre-renovated homes (0.01 ppm) (p = 0.004). Questionnaire data showed that opening of windows occurred less frequently in homes immediately post-renovation compared to pre-renovation; this factor likely affected the levels of indoor black carbon (from outdoor sources) and formaldehyde (from indoor sources) more than the renovation status itself.

    Measuring quality of care is essential to improve primary care. Quality of primary care for patients is usually assessed by patient satisfaction questionnaires. However, patients may not be able to judge quality of care without also reflecting their perception of the environment. We determined the effect that redesigning a primary care office had on patient satisfaction. We hypothesized that renovating the interior would make patients more satisfied with the quality of medical care. We performed a Pretest-Posttest analysis in a recently renovated single-practice primary care office in Grenchen, Switzerland. Before and after renovation, we distributed a questionnaire to assess patient satisfaction in four domains. We chose a Likert scale (1 = very poor to 6 = very good), and 12 quality indicators, and included two consecutive samples of patients presenting at the primary care office before (n = 153) and after (n = 153) interior design renovation. Response rate was high (overall 85 %). The sample was similar to the enlisted patient collective, but the sample population was older (60 years) than the collective (52 years). Patient satisfaction was higher for all domains after the office was renovated (p patient satisfaction, including satisfaction in domains otherwise unchanged. Physician skills and patient satisfaction sometimes depend on surrounding factors that may bias the ability of patients to assess the quality of medical care. These biases should be taken into account when quality assessment instruments are designed for patients.

    In this work, an industry-based and team-oriented education model was established based on a traditional mechanical engineering (ME) senior design class in order to better prepare future engineers and leaders so as to meet the increasing demand for high-quality engineering graduates. In the renovated curriculum, industry-sponsored projects became the most important course component and critical assessment tool, from which problem-solving skills as well as employability skills of the ME students can be fully developed. Hands-on experiences in finite element analysis (FEA) modelling and simulation were also added into the renovated curriculum to promote the application of FEA on engineering design and assessment. Evaluation of the renovated course was conducted using two instruments and the results have shown that the course made the ME senior students more prepared for their future career and a win-win model was created between the industry partner and the ME programme through it. Impact of the renovated syllabus on Accreditation Board for Engineering Technology goals was discussed. Based on the current progress, a more substantial change is being planned to further improve the effectiveness and practicability of this design course. The renovated course was started to offer to the ME senior students at Mississippi State University.

    25% of US households utilize onsite wastewater treatment systems (OWTS) for wastewater management. Advanced technologies were designed to overcome the inadequate wastewater treatment by conventional OWTS in critical shallow water table areas, such as coastal zones, in order to protect ground water quality. In addition to the septic tank and soil drainfield that comprise a conventional OWTS, advanced systems claim improved water renovation with the addition of sand filtration, timed dosing controls, and shallow placement of the infiltrative zone. We determined water quality renovation functions under current water table and temperature conditions, in anticipation of an experiment to measure OWTS response to a climate change scenario of 30-cm increase in water table elevation and 4C temperature increase. Replicate (n=3) intact soil mesocosms were used to evaluate the effectiveness of drainfields with a conventional wastewater delivery (pipe-and-stone) compared to two types of pressurized, shallow narrow drainfield. Results under steady state conditions indicate complete removal of fecal coliform bacteria, phosphorus and BOD by all soil-based systems. By contrast, removal of total nitrogen inputs was 16% in conventional and 11% for both advanced drainfields. Effluent waters maintained a steady state pH between 3.2 - 3.7 for all technologies. Average DO readings were 2.9mg/L for conventional drainfield effluent and 4.6mg/L for advanced, showing the expected oxygen uptake with shallow placement of the infiltrative zone. The conventional OWTS is outperforming the advanced with respect to nitrogen removal, but renovating wastewater equivalently for all other contaminants of concern. The results of this study are expected to facilitate development of future OWTS regulation and planning guidelines, particularly in coastal zones and in the face of a changing climate.

    Development of US Appalachian coal mining regions has been hampered by lack of domestic waste disposal technologies suited to fills. The suitability of on-site wastewater treatment and disposal systems (OSWTDS) in fill material is uncertain due to the effects of surface mining on soil physical properties. This research evaluated the potential for renovation of N and P present in domestic wastewater by fills from mining operations. N and P were chosen because of their potential adverse environmental impacts. Soil-fill (a mixture of Jefferson, fine-loamy, siliceous, mesic Typic Hapludult and Muskingom, fine-loamy, mixed, mesic Typic Dystrochrept soils) and minespoil (spoil)-fill (blasted rock material associated with the Taggart Marker and Low Splint Bench coal seams of the Upper Middle Wise Formation) were used. Septic tank effluent (STE) and sand filter effluent (SFE) were applied to spoil-fill columns at four loading rates and spoil-fill columns at one loading rate for a period of 20 wk. Renovation of wastewater was assessed by determining the concentration of N and P present in column leachate. Reduction of inorganic N(NO 3 - + NH 4 + ), based on N/Cl ratios ranged from 14.9 to 32.1% after the varying application rates of STE and SFE passed through the soil columns. However, leachate NO 3 - -N concentrations were still above the 10 mg -1 drinking water standard. The quantity of P emerging from the spoil-fill columns (3.0 mg PL -1 ) was higher than anticipated and may be related to the indigenous P present in the minespoil. Sorption of P in the spoil-fill column decreased with increased STE and SFE application (reduction ranged from 99.1 to 74.4%). Results from this study indicate that there is potential for renovating wastewater in OSWTDS in selected soil-fill areas in reclaimed minelands. 33 refs., 2 figs., 4 tabs

    Highlights: ► We developed a waste estimation system leveraging the BIM technology. ► The system can calculate waste disposal charging fee and pick-up truck demand. ► We presented an example scenario demonstrating this system. ► Automatic, time-saving and wide applicability are the features of the system. - Abstract: Due to the rising worldwide awareness of green environment, both government and contractors have to consider effective construction and demolition (C and D) waste management practices. The last two decades have witnessed the growing importance of demolition and renovation (D and R) works and the growing amount of D and R waste disposed to landfills every day, especially in developed cities like Hong Kong. Quantitative waste prediction is crucial for waste management. It can enable contractors to pinpoint critical waste generation processes and to plan waste control strategies. In addition, waste estimation could also facilitate some government waste management policies, such as the waste disposal charging scheme in Hong Kong. Currently, tools that can accurately and conveniently estimate the amount of waste from construction, renovation, and demolition projects are lacking. In the light of this research gap, this paper presents a building information modeling (BIM) based system that we have developed for estimation and planning of D and R waste. BIM allows multi-disciplinary information to be superimposed within one digital building model. Our system can extract material and volume information through the BIM model and integrate the information for detailed waste estimation and planning. Waste recycling and reuse are also considered in our system. Extracted material information can be provided to recyclers before demolition or renovation to make recycling stage more cooperative and more efficient. Pick-up truck requirements and waste disposal charging fee for different waste facilities will also be predicted through our system. The results

  11. The role of interfacial layers in the enhanced thermal conductivity of nanofluids: A renovated Hamilton-Crosser model

    International Nuclear Information System (INIS)

    Yu, W; Choi, S.U.S.

    2004-01-01

    We previously developed a renovated Maxwell model for the effective thermal conductivity of nanofluids and determined that the solid/liquid interfacial layers play an important role in the enhanced thermal conductivity of nanofluids. However, this renovated Maxwell model is limited to suspensions with spherical particles. Here, we extend the Hamilton--Crosser model for suspensions of nonspherical particles to include the effect of a solid/liquid interface. The solid/liquid interface is described as a confocal ellipsoid with a solid particle. The new model for the three-phase suspensions is mathematically expressed in terms of the equivalent thermal conductivity and equivalent volume fraction of anisotropic complex ellipsoids, as well as an empirical shape factor. With a generalized empirical shape factor, the renovated Hamilton--Crosser model correctly predicts the magnitude of the thermal conductivity of nanotube-in-oil nanofluids. At present, this new model is not able to predict the nonlinear behavior of the nanofluid thermal conductivity

    Thiago Cavalcante Nascimento

    Full Text Available Este artigo tem por objetivo verificar como as ações do sistema setorial brasileiro de energia eólica se relacionam com as perspectivas econômicas, sociais e ambientais que caracterizam inovações sustentáveis. Argumenta que as questões energéticas estão no cerne do desenvolvimento humano ao longo de sua história e que, em decorrência do atual cenário de mudanças climáticas, o desenvolvimento de fontes alternativas de energia é de vital importância na contemporaneidade. Metodologicamente, o estudo pode ser considerado exploratório e descritivo em relação aos fins e bibliográfico no que diz respeito aos meios. Foram utilizados dados primários de agências nacionais, regionais e mundiais de energia eólica para aumentar a consistência das informações coletadas e do trabalho como um todo. Os resultados evidenciam que o sistema setorial de energia eólica está estruturado em torno de uma série de instituições públicas, autarquias, associações de pesquisa e outros stakeholders que demonstram crescente interesse no desenvolvimento do setor no país. Os dados indicam, ainda, que os valores alcançados ao longo dos últimos leilões de energia eólica têm evidenciado o potencial de competitividade dessa fonte energética em comparação com as demais. Conclusivamente, é possível verificar que os pilares da sustentabilidade podem ser visualizados ao longo de praticamente todas as questões envolvendo a implantação de novas usinas eólicas, mas que a dimensão econômica ainda é a de maior destaque, tornando as dimensões sociais e ambientais dependentes da capacidade dessa modalidade de energia competir com outras.

    Helsinki Energia has started a new business activity - district cooling. The service is offered to cooling of large buildings, e.g. shopping centers, offices, etc. District cooling power is generated centrally at the power plant and the cooling power is transferred to the customer via separated distribution network. There are three main alternatives for production of district cooling power, mainly compressors, absorption devices and heat pumps. The operating energies required by them include electric power, district heat, steam, burning matter or some waste heat. The conditions for profitable district cooling are that the buildings to be cooled are built on a compact area at a reasonable distance from the district cool generation plant, that there enough need for district cool at the area, and that the district cool production plant is located at the seaside. Technically and economically reasonable construction of district cooling network requires that both the transmissions and distribution networks are as short as possible because the pipe dimensions are large, and because the streets are full of other infrastructure. Location near a sea ease the cooling of the district cool generation process, and especially, it is possible to use the coldness of the seawater directly via heat exchangers. The objective of district cool generation is to intensify the combined heat and power generation during warm seasons by reducing the electric power consumption and by increasing the utilization of surplus heat. It is also possible to reduce the use of harmful refrigerants. The district cooling activities of Helsinki Energia started in 1998 in Pitaejaenmaeki. Ruoholahti district cool system is the first larger area district cool project in Finland. The district cooling plant is constructed at the area of the Salmisaari power plant, hence the plant can utilize the present space and equipment of the power plant in generation of district cool.

    In the process of nuclear power development there comes a phase when the old' power-units, which reactor installations have expired the designed and extended service lifetime are withdrawn from operating. At this phase in the case of the same annual investments into nuclear power, the increase of the total set up capacity of the nuclear power will be terminated because introduction of capacities due to construction of 'new' power-units only compensates for the reduction of capacities caused by withdrawing from operating the 'old' power-units. Along with this, taking into account a sizeable difference in the service lifetime of the nuclear steam supplying systems and the rest infrastructure of the nuclear power plants, it is an opportunity to find the solution to the problem of compensating for the withdrawn capacities without considerable increasing the annual investments. This opportunity is connected with use of the innovative nuclear power technology based on multipurpose small power modular fast reactors with lead-bismuth coolant for replacement of the withdrawn capacities (renovation of power-units). The features of the innovative nuclear power technology based on the SVBR-76/100 reactor installations, the results of the technical and economical investigations that demonstrate the high economical efficiency of use of the renovation technology using the SVBR-75/100 reactor modules are presented in the Paper.

  1. The Phenomenon of Trust in Flat Owners’ Collective Renovation Strategies in Estonia

    Directory of Open Access Journals (Sweden)

    Liis Ojamäe

    2015-12-01

    Full Text Available Mobilising fl at owners into renovating residential blocks in post-socialist countries has been a complicated process. Evidence from Estonia shows that the success of collective renewal strategies depends not only on economic issues but also on ways investments are organised and, signifi cantly, the relationship of trust between diff erent actors. The paper aims at conceptualising the issue of institutional trust upon the experience of urban housing renewal in Estonia. It is contended that trust is crucial for the joint decision-making in a block as well as for facilitating negotiations between fl at owners’ associations, local municipalities and market actors. The paper draws on three qualitative studies conducted in Estonia during the 2000s, which allow asserting that trust towards new strategies of housing renewal can be achieved and maintained by ‘best practices’, which by concentrating expert knowledge also denote direct communication between experts and fl at owners. While it is important to raise the residents’ technical knowledgeability, it is indispensable to develop abilities to manage and communicate the renovation process between diff erent parties. The public sector is conceived to be a central actor in sustaining trust between actors who have no previous positive experience from collective residential strategies

    Buildings constitute 42.5 per cent of the energy consumption in Europe. As such, the building sector represents a high potential for innovation in terms of reducing global energy consumption. Since existing buildings represent a large part of the built environment, refurbishment is an important issue to consider. However, efficient processes of renovation must be well defined. France's National Institute of Solar Energy has developed a methodology to reduce consumption of primary energy use and decrease greenhouse gas emissions in the built environment, while increasing user comfort. The methodology places much emphasis on the health and comfort of occupants from the very beginning of the process. The methodology was developed to make the building renovation process more efficient by elaborating generic guidelines and tools. In this study, an office building from the 1970s was refurbished and monitored for both energy performance and comfort. The objective was to better understand the technological and psychosocial aspects involved in refurbishing an old building. Measurements were compared with the perception of the occupants. The impacts of human interaction on the building behaviour was also evaluated. 6 refs., 1 tab., 4 figs.

    The CABRI experimental pulse reactor, located at the Cadarache nuclear research center, southern France, is devoted to the study of Reactivity Initiated Accidents (RIA). For the purpose of the CABRI International Program (CIP), managed and funded by IRSN, in the framework of an OECD/NEA agreement, a huge renovation of the facility has been conducted since 2003. The Cabri Water Loop was then installed to ensure prototypical Pressurized Water Reactor (PWR) conditions for testing irradiated fuel rods. The hodoscope installed in the CABRI reactor is a unique online fuel motion monitoring system, operated by IRSN and dedicated to the measurement of the fast neutrons emitted by the tested rod during the power pulse. It is one of the distinctive features of the CABRI reactor facility, which is operated by CEA. The system is able to determine the fuel motion, if any, with a time resolution of 1 ms and a spatial resolution of 3 mm. The hodoscope equipment has been upgraded as well during the CABRI facility renovation. This paper presents the main outcomes achieved with the hodoscope since October 2015, date of the first criticality of the CABRI reactor in its new Cabri Water Loop configuration. Results obtained during reactor commissioning phase functioning, either in steady-state mode (at low and high power, up to 23 MW) or in transient mode (start-up, possibly beyond 20 GW), are discussed.

    Received Signal Strength Indicator (RSSI) localization using fingerprint has become a prevailing approach for indoor localization. However, the fingerprint-collecting work is repetitive and time-consuming. After the original fingerprint radio map is built, it is laborious to upgrade the radio map. In this paper, we describe a Fingerprint Renovation System (FRS) based on crowdsourcing, which avoids the use of manual labour to obtain the up-to-date fingerprint status. Extended Kalman Filter (EKF) and Gaussian Process Regression (GPR) in FRS are combined to calculate the current state based on the original fingerprinting radio map. In this system, a method of subset acquisition also makes an immediate impression to reduce the huge computation caused by too many reference points (RPs). Meanwhile, adjusted cosine similarity (ACS) is employed in the online phase to solve the issue of outliers produced by cosine similarity. Both experiments and analytical simulation in a real Wireless Fidelity (Wi-Fi) environment indicate the usefulness of our system to significant performance improvements. The results show that FRS improves the accuracy by 19.6% in the surveyed area compared to the radio map un-renovated. Moreover, the proposed subset algorithm can bring less computation.

    Green eco-friendly housing includes approaches to reduce indoor air pollutant sources and to increase energy efficiency. Although sealing/tightening buildings can save energy and reduce the penetration of outdoor pollutants, an adverse outcome can be increased buildup of pollutants with indoor sources. The objective of this study was to determine the differences in the indoor air quality (IAQ) between green and non-green homes in low-income housing complexes. In one housing complex, apartments were renovated using green principles (n=28). Home visits were conducted immediately after the renovation, and subsequently at 6 months and at 12 months following the renovation. Of these homes, eight homes had pre-renovation home visits; this allowed pre- and post-renovation comparisons within the same homes. Parallel visits were conducted in non-green (control) apartments (n=14) in a nearby low-income housing complex. The IAQ assessments included PM2.5, black carbon, ultrafine particles, sulfur, total volatile organic compounds (VOCs), formaldehyde, and air exchange rate. Data were analyzed using linear mixed-effects models. None of the indoor pollutant concentrations were significantly different between green and non-green homes. However, we found differences when comparing the concentrations before and after renovation. Measured immediately after renovation, indoor black carbon concentrations were significantly lower averaging 682 ng/m(3) in post-renovation vs. 2364 ng/m(3) in pre-renovation home visits (p=0.01). In contrast, formaldehyde concentrations were significantly higher in post-renovated (0.03 ppm) than in pre-renovated homes (0.01 ppm) (p=0.004). Questionnaire data showed that opening of windows occurred less frequently in homes immediately post-renovation compared to pre-renovation; this factor likely affected the levels of indoor black carbon (from outdoor sources) and formaldehyde (from indoor sources) more than the renovation status itself. To reduce IAQ

    CPF (Chemical Processing Facility) was constructed at Nuclear Fuel Cycle Engineering Laboratories of JAEA (Japan Atomic Energy Agency) in 1980 as a basic research field where spent fuel pins from fast reactor (FR) and high level liquid waste can be dealt with. The renovation consists of remodeling of the CA-3 cell and the laboratory A, installation of globe boxes, hoods and analytical equipments to the laboratory C and the analytical laboratory. Also maintenance equipments in the CA-5 cell which had been out of order were repaired. The CA-3 cell is the main cell in which important equipments such as a dissolver, a clarifier and extractors are installed for carrying out the hot test using the irradiated FR fuel. Since the CPF had specialized originally in the research function for the Purex process, it was desired to execute the research and development of such new, various reprocessing processes. Formerly, equipments were arranged in wide space and connected with not only each other but also with utility supply system mainly by fixed stainless steel pipes. It caused shortage of operation space in flexibility for basic experimental study. Old equipments in the CA-3 cell including vessels and pipes were removed after successful decontamination, and new equipments were installed conformably to the new design. For the purpose of easy installation and rearranging the experimental equipments, equipments are basically connected by flexible pipes. Since dissolver is able to be easily replaced, various dissolution experiments is conducted. Insoluble residue generated by dissolution of spent fuel is clarified by centrifugal. This small apparatus is effective to space-saving. Mini mixer settlers or centrifugal contactors are put on to the prescribed limited space in front of the backside wall. Fresh reagents such as solvent, scrubbing and stripping solution are continuously fed from the laboratory A to the extractor by the reagent supply system with semi-automatic observation

    The pumping systems provide about 20 to 25 percent of energy which is necessary worldwide: it is fruitful to understand how to use electric power efficiently, to achieve the reduction regarding expenses a pumping system implies.It is essential to possess a better knowledge about the pumping system and its applications, in order to be able to use energy responsibly. If people do not how to operate this kind of systems properly, they will use inadequate equipment that will cause an energy waste. In addition it is important to know: alternative methods to meet variable demands, an adapted system to pump water requirements in order to ensure the pump work in its pumping point, and the life cycle system cost for the energy saving in the long term. [Spanish] En promedio del 20 al 25% de la energia necesaria en el mundo proviene de los sistemas de bombeo, por tal razon es importante saber como utilizar la energia electrica con eficiencia para asi lograr reducir los gastos que este tipo de sistemas implican. Para poder hacer un buen uso de la energia, es necesario que se tenga un conocimiento mayor del sistema de bombeo y aplicacion, ya que la ignorancia sobre esto exige el uso de aparatos que contribuyen al desperdicio de la energia; por otro lado tambien es esencial conocer metodos alternos para demandas variables, tener un sistema que se adapte a las necesidades de bombeo del agua para asegurarse de que cada bomba trabaje cerca de su punto de bombeo y finalmente conocer el costo del ciclo de vida del sistema para el ahorro de energia a largo plazo.

    Aiming at serious slag on the water wall around the burner of corner-fired boiler with low-ash-fusion-point coal, cold experimental model has been established. In this experiment, particle image velocimetry (PIV) has been employed to accurately measure aerodynamic field of burner region, and the experimental research of furnace slag renovation has been conducted through changing the burner jet arrangement. The experiment results show that it has significantly effect on aerodynamic field in the furnace by changing burner jet deflection angle. A reasonable actual tangential circle diameter can be formed through adjusting the burner jet deflection angle, to prevent primary air attacking the wall, and further more, to effectively prevent serious slag on the water wall around the burner.

    Questions of whether past nuclear regulatory body of Korea is not a proper system to monitor and check the country's nuclear energy policy and utilization have been raised. Moreover, a feeling of insecurity regarding nuclear safety after the nuclear accident in Japan has spread across the public. This has stimulated a renovation of the nuclear safety regime in Korea. The Nuclear Safety and Security Commission (NSSC) was launched on October 26, 2011 as a regulatory body directly under the President in charge of strengthening independence and nuclear safety. This was a meaningful event as the NSSC it is a much more independent regulatory system for Korea. However, the NSSC itself does not guarantee an enhanced public acceptance of the nuclear policy and stable use nuclear energy. This study introduces the new NSSC system and its details in terms of organization structure, appropriateness of specialty, budget stability, and management system. (authors)

    The design of nuclear power plants on anti-flood performance was only based on design basis condition in China. The Fukushima nuclear accident revealed the possibility of suffering flood under beyond design basis condition, which caused the continuously deterioration of Fukushima nuclear accident. After the accident, China national nuclear safety regulators proposed new requirements on performance of anti-flood of nuclear power plants. Then, Qinshan Phase II carried out research of anti-flood technology. This paper introduced the background, research and development of anti-flood renovation technology for important safety buildings of Qinshan Phase II, and discussed the necessary for improvement of anti-flood capacity of nuclear power plants and relative measures in China, which is helpful to improve anti-flood performance of operational nuclear power plants and nuclear power plants under construction.

    that the average Danish single-family house owner can be motivated by improvements in comfort, indoor environment and architecture combined with a reasonable economy. The objective of this paper is, based on the motivation survey results, to determine if all homeowners can be assumed as one homogeneous group...... or if there are significant differences among the homeowners, what causes these differences and how does this affect the future motivation strategy. The key parameters for if and how the homeowner can be motivated are related to the homeowner’s position in life: age, children’s’ age, time of ownership, occupation and income....... Furthermore, the results conclude that the homeowners cannot be assumed as one group, but must be seen as individuals. Those who are most likely to be motivated to perform an energy renovation are the younger generation of homeowners. The older generation will be harder to motivate, but results nonetheless...

    The report covers the reliability assessment of the startup channel-B of the PARR-1 renovated instrumentation and Control. For startup channel-A, a separate report (DNSRP-10(7)/88) was prepared in 1988. As the modules are of different origins in both the channels, a separate calculation was necessary. In the report the overall unreliability of the startup channel has been calculated by considering 1 out of 2 operation mode. In the assessment, the reliability calculations for the channel has been performed using similar assumptions as used in the authors' report on startup channel-A. For the analysis the Component Count Method (CCM) was applied. Comparison of results for channel-A and channel-B were made.

    Health disparities in low-income communities may be linked to residential exposures to chemicals infiltrating from the outdoors and characteristics of and sources in the home. Indoor sources comprise those introduced by the occupant as well as releases from building materials. To examine the impact of renovation on indoor pollutants levels and to classify chemicals by predominant indoor sources, we collected indoor air and surface wipes from newly renovated "green" low-income housing units in Boston before and after occupancy. We targeted nearly 100 semivolatile organic compounds (SVOCs) and volatile organic compounds (VOCs), including phthalates, flame retardants, fragrance chemicals, pesticides, antimicrobials, petroleum chemicals, chlorinated solvents, and formaldehyde, as well as particulate matter. All homes had indoor air concentrations that exceeded available risk-based screening levels for at least one chemical. We categorized chemicals as primarily influenced by the occupant or as having building-related sources. While building-related chemicals observed in this study may be specific to the particular housing development, occupant-related findings might be generalizable to similar communities. Among 58 detected chemicals, we distinguished 25 as primarily occupant-related, including fragrance chemicals 6-acetyl-1,1,2,4,4,7-hexamethyltetralin (AHTN) and 1,3,4,6,7,8-hexahydro-4,6,6,7,8,8-hexamethylcyclopenta[g]-2-benzopyran (HHCB). The pre- to post-occupancy patterns of the remaining chemicals suggested important contributions from building materials for some, including dibutyl phthalate and xylene, whereas others, such as diethyl phthalate and formaldehyde, appeared to have both building and occupant sources. Chemical classification by source informs multi-level exposure reduction strategies in low-income housing. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

  6. Barriers and Potential Solutions for Energy Renovation of Buildings in Denmark

    Directory of Open Access Journals (Sweden)

    Niels I. Meyer

    2014-02-01

    Full Text Available Buildings account for a substantial part of the total energy consumption. In Denmark this number is about 40 % and this is approximately the same in most industrial countries. On this background there is an urgent need to develop strategies for reducing the energy demand in the building sector. Renovation of existing buildings must have high priority as houses often last for 50 to 100 years, while the time perspective for the desired transformation to low-energy houses is less than 30 years in order to mitigate global warming and avoid irreversible tipping-points. The only sustainable energy supply in the perspective of centuries is renewable energy provided by the sun and exploited in the form of solar heat, solar electricity (PVs, wind power, hydropower, wave power, and some types of biomass etc. A future dominating role of intermittent renewable sources requires new integrated systems thinking on both the supply and demand side for heat, electricity and transport. Implementing such Smart Energy Systems requires integrated strategic energy planning on the national and local level. With the fundamental changes in the energy supply technologies expected during the coming years, it is important to synchronize investments in energy conservation measures with investments in the supply side, in order to avoid overinvestment in supply systems and thus to minimize the total costs of the transformation to Smart Energy Systems. This paper highlights some of the most important barriers for renovation of existing buildings in Denmark and points to policies for overcoming these barriers. Some of the policies have been presented in the reports of a recent Danish research project (CEESA

    Full Text Available A necessidade premente de aumento no número de mudas plantadas anualmente, bem como a crescente diminuição na disponibilidade de matérias-primas tradicionais para composição de substratos, tem levado à necessidade do desenvolvimento de estudos que visam à avaliação e disponibilização de novos materiais para sua composição técnica e economicamente eficientes. Em vista disso, este estudo objetivou analisar as propriedades físicas e químicas de substratos formulados com base em materiais renováveis e de grande disponibilidade (fibra de coco, casca de arroz carbonizada em diferentes granulometrias, biossólido e casca de pinus semidecomposta, bem como suas intercorrelações. Para tanto, foram formulados 41 substratos, os quais tiveram suas propriedades físicas e químicas avaliadas. Com base nos resultados, pôde-se concluir que, pelas suas propriedades físicas e químicas, uma série de materiais renováveis e, ou, resíduos agroindustriais e humanos se adéquam para serem utilizados como componentes na formulação de substratos para produção de mudas florestais, embora os conteúdos de alguns nutrientes em determinados substratos devam ser ajustados via adubação de base. Em vista do fato de as propriedades físicas serem mais decisivas na escolha de determinada formulação de substrato, entre os componentes e misturas avaliadas se pode concluir que os substratos formulados à base de fibra de coco e casca de arroz carbonizada se mostraram mais adequados.

  8. Energy Efficiency and Universal Design in Home Renovations - A Comparative Review.

    2016-01-01

    Policy and societal objectives indicate a large need for housing renovations that both accommodate lifelong living and significantly increase energy efficiency. However, these two areas of research are not yet examined in conjunction and this paper hypothesizes this as a missed opportunity to create better renovation concepts. The paper outlines a comparative review on research in Energy Efficiency and Universal Design in order to find the similarities and differences in both depth and breadth of knowledge. Scientific literature in the two fields reveals a disparate depth of knowledge in areas of theory, research approach, and degree of implementation in society. Universal Design and Energy Efficiency are part of a trajectory of expanding scope towards greater sustainability and, although social urgency has been a driver of the research intensity and approach in both fields, in energy efficiency there is an engineering, problem solving approach while Universal Design has a more sociological, user-focused one. These different approaches are reflected in the way home owners in Energy Efficiency research are viewed as consumers and decision makers whose drivers are studied, while Universal Design treats home owners as informants in the design process and studies their needs. There is an inherent difficulty in directly merging Universal Design and Energy Efficiency at a conceptual level because Energy Efficiency is understood as a set of measures, i.e. a product, while Universal Design is part of a (design) process. The conceptual difference is apparent in their implementation as well. Internationally energy efficiency in housing has been largely imposed through legislation, while legislation directly mandating Universal Design is either non-existent or it has an explicit focus on accessibility. However, Energy Efficiency and Universal Design can be complementary concepts and, even though it is more complex than expected, the combination offers possibilities to advance

    The Nuclear Materials Storage Facility (NMSF) at the Los Alamos National Laboratory (LANL) was a Fiscal Year (FY) 1984 line-item project completed in 1987 that has never been operated because of major design and construction deficiencies. This renovation project, which will correct those deficiencies and allow operation of the facility, is proposed as an FY 97 line item. The mission of the project is to provide centralized intermediate and long-term storage of special nuclear materials (SNM) associated with defined LANL programmatic missions and to establish a centralized SNM shipping and receiving location for Technical Area (TA)-55 at LANL. Based on current projections, existing storage space for SNM at other locations at LANL will be loaded to capacity by approximately 2002. This will adversely affect LANUs ability to meet its mission requirements in the future. The affected missions include LANL's weapons research, development, and testing (WRD ampersand T) program; special materials recovery; stockpile survelliance/evaluation; advanced fuels and heat sources development and production; and safe, secure storage of existing nuclear materials inventories. The problem is further exacerbated by LANL's inability to ship any materials offsite because of the lack of receiver sites for mate rial and regulatory issues. Correction of the current deficiencies and enhancement of the facility will provide centralized storage close to a nuclear materials processing facility. The project will enable long-term, cost-effective storage in a secure environment with reduced radiation exposure to workers, and eliminate potential exposures to the public. This report is organized according to the sections and subsections. It is organized into seven parts. This document, Part V, Section B - Structural/Seismic Information provides a description of the seismic and structural analyses performed on the NMSF and their results

    Any discussion of 21st century energy trends must take into account the global energy imbalance. Roughly 1.6 billion people still lack access to modern energy services, and few aspects of development - whether related to living standards, health care or industrial productivity - can take place without the requisite supply of energy. As we look to the century before us, the growth in energy demand will be substantial, and 'connecting the unconnected' will be a key to progress. Another challenge will be sustainability. How can we meet these growing energy needs without creating negative side effects that could compromise the living environment of future generations? Nuclear power is not a 'fix-all' option. It is a choice that has a place among the mix of solutions, and expectations for the expanding use of nuclear power are rising. In addition to the growth in demand, these expectations are driven by energy security concerns, nuclear power's low greenhouse gas emissions, and the sustained strong performance of nuclear plants. Each country must make its own energy choices; one size does not fit all. But for those countries interested in making nuclear power part of their sustainable development strategies, it is important that the nuclear power option be kept open and accessible [Spanish] En cualquier analisis de las tendencias energeticas del siglo XXI hay que tomar en cuenta el desequilibrio energetico mundial. Aproximadamente 1 600 millones de persona aun no tienen acceso a servicios energeticos modernos, y pocos aspectos del desarrollo - ya se trate de los niveles de vida, la atencion sanitaria o la productividad industrial - pueden conseguirse sin el necesario suministro de energia. Si consideramos el siglo que tenemos por delante, vemos que el crecimiento de la demanda energetica sera sustancial y que una clave del progreso consistira en 'conectar a los que carecen de conexion'. Otro desafio sera la sostenibilidad. Como podemos satisfacer estas necesidades

    Full Text Available O presente artigo tem como objetivo analisar os aspectos jurídicos do panorama regulatório da produção e comercialização do biodiesel no Brasil, no contexto internacional de crescente demanda energética, onde os biocombustíveis surgem como uma alternativa renovável aos combustíveis fósseis. A metodologia empregada neste trabalho é de cunho qualitativo, com análise bibliográfica e documental da legislação brasileira e internacional. A conclusão a que se chega é que os biocombustíveis apresentam grande potencial para se tornarem uma importante fonte sustentável de energia para o País, além da possibilidade de contribuírem para a melhoria do seu quadro social, através do desenvolvimento de programas de governo que contemplam a sua produção pelos agricultores familiares. A contribuição deste trabalho decorre da constatação de que a Agência Nacional do Petróleo, Gás Natural e Biocombustíveis (ANP, órgão regulador das atividades relacionadas ao biodiesel no Brasil, tem seu foco nos aspectos econômicos como fundamento à sua atividade interventiva, especialmente na proteção ao consumidor. Excluída das atribuições da agência reguladora, a efetiva concretização da expressiva dimensão social ligada ao biodiesel, entretanto, carece de ações governamentais no sentido de implementar políticas de planejamento agrícola adequadas a cada região do país, conferindo suporte ao sistema cooperativo, bem como apoio técnico-financeiro ao agricultor familiar, a fim de elevá-lo a partícipe-chave neste contexto.
