A semiotic framework for information representation of energy consumption in office buildings

Taking a perspective from a whole building lifecycle, occupier's actions could account for about 50% of energy. However occupants' activities influence building energy performance is still a blind area. Building energy performance is thought to be the result of a combination of building fabrics, building services and occupants' activities, along with their interactions. In this sense, energy consumption in built environment is regarded as a socio-technical system. In order to understand how such a system works, a range of physical, technical and social information is involved that needs to be integrated and aligned. This paper has proposed a semiotic framework to add value for Building Information Modelling, incorporating energy-related occupancy factors in a context of office buildings. Further, building information has been addressed semantically to describe a building space from the facility management perspective. Finally, the framework guides to set up building information representation system, which can help facility managers to manage buildings efficiently by improving their understanding on how office buildings are operated and used.

Gas-filled, flat plate solar collectors

This work treats the thermal and mechanical performances of gas-filled, flat plate solar collectors in order to achieve a better performance than that of air filled collectors. The gases examined are argon, krypton and xenon which all have lower thermal conductivity than air. The absorber is formed as a tray connected to the glass. The pressure of the gas inside is near to the ambient and since the gas volume will vary as the temperature changes, there are potential risks for fatigue in the material. One heat transfer model and one mechanical model were built. The mechanical model gave stresses and information on the movements. The factors of safety were calculated from the stresses, and the movements were used as input for the heat transfer model where the thermal performance was calculated. It is shown that gas-filled, flat plate solar collectors can be designed to achieve good thermal performance at a competitive cost. The best yield is achieved with a xenon gas filling together with a normal thick absorber, where normal thick means a 0.25 mm copper absorber. However, a great deal of energy is needed to produce the xenon gas, and if this aspect is taken into account, the krypton filling is better. Good thermal performance can also be achieved using less material; a collector with a 0.1 mm thick copper absorber and the third best gas, which is argon, still gives a better operating performance than a common, commercially produced, air filled collector with a 0.25 mm absorber. When manufacturing gas-filled flat plate solar collectors, one way of decreasing the total material costs significantly, is by changing absorber material from copper to aluminium. Best yield per monetary outlay is given by a thin (0.3 mm) alu-minium absorber with an argon filling. A high factor of safety is achieved with thin absorbers, large absorber areas, rectangular constructions with long tubes and short distances between glass and absorber. The latter will also give a thin layer of gas which gives good thermal performance. The only doubtii ful construction is an argon filled collector with a normal thick (> 0.50 mm) aluminium absorber. In general, an assessment of the stresses for the proposed construction together with appropriate tests are recommended before manufacturing, since it is hard to predict the factor of safety; if one part is reinforced, some other parts can experience more stress and the factor of safety actually drops.

Políticas públicas municipais de saúde: fortalecendo a democracia em pequenos municípios brasileiros

This article presents the endeavors of health municipal teams in building services that meet citizens’ demands, in a small municipality from a less developed area of the state of São Paulo. Beyond health services practice characterization and organization, our study assesses the challenges and advances in the implementation of public, health policies in Brazil. In this way it is possible to perceive how the family health strategy needs to overcome impasses in the service work processes, as well as more dynamic local and regional relations to provide comprehensive care to citizens. Health care exemplifies how, in democracy building, municipal action is indispensable to strengthen the effectiveness of public actions.

Los residuos de envases y embalajes en edificación residencial. Patrones de generación y estrategias de mejora de su gestión

Uno de los retos a los que se enfrenta la humanidad es la demanda de una sociedad con casi cero residuos: la búsqueda de una economía más eficiente en el uso de los recursos teniendo en cuenta el cambio climático y un abastecimiento sostenible de materias primas que permitan satisfacer las necesidades de una población mundial cada vez mayor, dentro de los límites sostenibles de los recursos naturales del planeta. Abordar este desafío implica la recuperación y reciclaje de materiales para reducir consumos de materias primas y, para ello, debe promoverse la innovación en la prevención y gestión de residuos, como estrategia hacia un desarrollo urbano sostenible. Los envases y embalajes forman parte de la cultura actual, relacionándose con el grado de desarrollo de países y regiones; el sector de la construcción no es ajeno a la problemática y genera un importante volumen de embalajes en las obras que no se gestionan de forma adecuada. El modelo de gestión de Residuos de Construcción Demolición (RCD) actual es poco eficaz, ya que los vertederos siguen recibiendo grandes cantidades de residuos valorizables. La normativa ha conseguido minimizar las prácticas ilegales, pero se comprueba que la gestión actual de los RCD en obra deja en manos de las plantas de tratamiento la misión de separar los residuos según su naturaleza y los datos aportados por las distintas plantas no permiten afirmar el grado de alcance de dicho objetivo, ni el destino de los mismos. Los envases y embalajes son un tipo de residuos que por su naturaleza suponen una fuente de recursos valorizables y por ello están presentes en directivas y leyes, dirigidas fundamentalmente al sector de la alimentación. En el ámbito de la construcción, hasta la fecha, no se habían tratado de forma específica, motivo que justifica este trabajo. Esta Tesis Doctoral tiene como objetivo principal mejorar la gestión de residuos de embalajes procedentes de materiales de construcción. Para ello se estudia un importante conjunto de obras de edificación residencial colectiva de 1173 viviendas, análisis que llevará a conocer los patrones de producción de los Residuos de Envases y Embalajes en Construcción (REEC) e identificar los productos o materiales responsables de su generación. La monitorización realizada, permitirá diseñar estrategias específicas que minimicen la generación de estos residuos y optimicen su valorización. Se ha podido comprobar que el tratamiento particularizado de los REEC puede mejorar los resultados de la gestión del conjunto de RCD, debido a que, al no mezclarse, se elimina un importante agente contaminador de los residuos inertes. Las obras analizadas alcanzan un nivel de segregación in situ muy bajo, y los capítulos de cerramientos e instalaciones suman más del 50% del global de REEC. Particularizando en cada tipo de material, el cartón predomina en los trabajos de electricidad, el plástico en las particiones y la madera en fachadas. Se evalúa la opción del eco-­‐rediseño para uno de los embalajes predominantes, y se identifican estrategias para minimizar su impacto. Se comprueba que el ahorro en la gestión de RCD en caso de impulsar la segregación in situ no es muy significativo en las obras estudiadas, si bien se demuestra que la viabilidad económica es el factor más importante para motivar a las empresas constructoras. Las Administraciones Públicas deberían incentivar la gestión responsable, estableciendo medidas de control en las plantas de tratamiento e implementando en sus obras medidas de gestión de RCD ejemplares para el mercado. Una adecuada planificación de la obra, y formación específica para el personal son medidas que facilitan la segregación in situ y mejoran los resultados. Los promotores, mediante su relación contractual con el resto de agentes, tienen la capacidad de establecer objetivos de reducción, planificación y gestión sostenible de los REEC. Por último, se propone un sistema de gestión de REEC, integrable dentro del Sistema de Gestión de la empresa constructora, que permite evitar que residuos valorizables tales como los envases y embalajes se envíen a vertedero, guiando al sector hacia un futuro más respetuoso, alineado con el desarrollo sostenible. ABSTRACT One of the challenges humanity faces is the demand of an almost zero waste society: the search for a more efficient economy in the use of resources, taking into account climate change and a sustainable supply of raw materials, that meet the needs of an increasing world population within the sustainable limits of the planet's natural resources. Addressing this challenge involves the recovery and recycling of materials to reduce consumption of raw materials, so innovation must therefore be promoted in the prevention and management of waste, as a strategy towards a sustainable urban development. Packaging is part of our current culture and is related to the degree of development of countries and regions; the construction sector is no stranger to this problem and generates a significant amount of packaging waste in the site works, which nowadays is not managed properly. The current Construction Demolition Waste (CDW) management model is ineffective, since landfills continue to receive large amounts of recoverable waste. The legislation has managed to minimize illegal practices, but it has been observed that the current management of CDW in the analysed works leaves the mission of separating waste according to their nature to the plants, and data provided by the latter does not allow for checking the scope of this objective, nor the destiny of the waste. Packaging is a type of waste which, by its nature, represents a source of recoverable resources and is therefore present in directives and laws, focused primarily on the food industry. It has not been specifically treated to date in the construction field, hence the reason that justifies this work. This Thesis aims to improve the management of packaging waste from construction materials. An important set of residential building works with 1173 dwellings is analysed, which leads to knowledge on the production patterns of packaging waste (PW) in the construction industry, and the identification of the products responsible for its generation. The monitorization also allows for the design of specific strategies which minimise the generation of waste and optimize recovery. It has been found that the individualized treatment of PW can improve the results of the management of the whole CDW since, when not mixed, a major pollutant of inert waste is removed. The analysed works reached a very low segregation level and the façades and building services phases account for more than 50% of the overall PW. Focusing on each type of material, cardboard predominates electricity works, plastic on partitions and wood on façades. Eco-­‐redesign is evaluated for one of the predominant packages, and strategies are identified to minimise their impact are . There is evidence that the savings in the CDW management in case of promoting segregation on site are not very significant at the studied works, although economic feasibility is the most important factor to motivate the construction companies. Public Administrations should encourage responsible management, establishing control measures in treatment plants and implementing CDW management exemplary measures on their work sites for the market. A proper planning of the works and specific training for the personnel are measures that facilitate in situ segregation and improve outcomes. The developers, through their contractual relationship with the other agents, have the ability to set reduction targets, planning and sustainable management of PW. Finally, a management system for PW is proposed, integrated within the Management System of the construction company, which aims to avoid that recoverable waste such as packaging is sent to landfill, leading the industry towards a more environmentally friendly future, aligned with sustainable development.

Auditoria Energética à Escola Secundária Padre Benjamim Salgado - Vila Nova de Famalicão

A dependência energética das grandes economias mundiais alertou o mundo para a necessidade de mudar o comportamento relativo ao consumo de energia. O aumento dos custos energéticos tem induzido ao uso racional da energia por parte das organizações, implicando uma monitorização permanente nas instalações. A eficiência energética é um tema que tem vindo a assumir grande importância nos dias de hoje na nossa sociedade, não só pelos compromissos internacionais assumidos, como também pelo combate ao desperdício energético. Esta dissertação relata o estágio curricular na Agência de Energia do Ave, que inclui uma auditoria energética à escola Padre Benjamim Salgado. O estágio visou essencialmente a contribuição para um modelo de desenvolvimento sustentável, na procura de alternativas com menor impacto ambiental, introduzindo conceitos de eficiência energética e ambiental nos processos de planeamento. Acções de sensibilização e auditorias energéticas foram os projetos que, durante o período curricular, tiveram maior intervenção por parte do autor desta dissertação, tendo em vista a mudança de hábitos de consumo energético na sociedade. A auditoria energética à escola Padre Benjamim Salgado, Joane Vila Nova de Famalicão, apresenta uma abordagem para a determinação da redução dos custos de energia, mantendo o conforto para os seus ocupantes. A escola em análise configura um Grande Edifício de Serviços (GES) à luz de uma análise térmica feita ao edifício escolar, com os valores de eferência atualizados, com entrada em vigor a 31 de dezembro de 2015, ao abrigo da nova regulamentação (decreto-lei n.º118/2013, 20 de Agosto) verificando-se o cumprimento dos requisitos mínimos definidos na Portaria n.º 349/2013 do atual decreto. Foi ainda efetuada, após um levantamento exaustivo, uma análise detalhada das faturas de energia, gás e água, e de todos os equipamentos consumidores de energia que se encontram instalados na instituição.

Enacted in 1935, Title V is a federal-state partnership that promotes and improves maternal and child health (MCH). According to each state’s unique needs, Title V supports a spectrum of services, from infrastructure building services like quality assurance and policy development, to gap-filling direct health care services. Title V resources are directed towards MCH priority populations: pregnant women, mothers, infants, women of reproductive years, children and adolescents and children and youth with special health care needs.

Building eResearch Services, Capabilities and Capacity

The Queensland University of Technology (QUT) is known for several flagship eResearch centres. It also has a number of mature, centralised research support services that address a several of areas of eResearch. The university has openly stated its aspiration to be an institution with a strongly embedded eResearch capability and to this end it has expressed the desire to establish a university-wide eResearch support service. However, articulating this desire is much easier than realising it. During 2008 QUT undertook a major review into eResearch that made recommendations on the development of university-wide eResearch support service and the building of eResearch capabilities and capacity throughout the university. The results of this review were reported last year at this conference. In 2009, QUT is progressing a second, follow-on project – Building eResearch Support Capability and Capacity. It has been designed to build upon existing strengths in HPC, repositories, data management, and the delivery of integrated skills for eresearch. The purpose of this presentation is to give an update on QUT’s journey, one year on from its first major report into eResearch. It will outline how the university is approaching this challenge, the current work being carried out and the strategies being employed. We will also discuss the lessons learned.
