McMath-Hulbert Observatory [Lake Angelus, MI]

Observatory is near Lake Angelus, Mich. (five miles north of Pontiac). 24" reflecting telescope began operations in July 1930; also included a 10 1/2" reflector. Established and deeded to the university by Robert R. McMath, Francis McMath, and Judge Henry S. Hulbert. An additional 50' tower telescope was added in 1935/ 1946 and 70' tower telescope and office building added in 1940. Image is photograph of a painting.

Institute of Science and Technology

On the North Camous of the Univeristy of Michigan at Ann Arbor, consists of three structures; a central office building, a laboratory unit and a high bay laboratory facility connected by underground corridors.

O desafio do aproveitamento de águas pluviais

Pretende-se com este trabalho avaliar a importância dos sistemas de aproveitamento de água da chuva como medida contributiva para a sustentabilidade dos recursos hídricos, a par do alerta para os preços praticados em Portugal, que comprometem a viabilidade deste tipo de sistema. Será também dada especial atenção à vulnerabilidade a que os referidos sistemas estão sujeitos, imposta pelos meses de Verão, onde os consumos de água são substancialmente maiores, mas durante os quais normalmente não ocorre precipitação. Após uma primeira componente teórica, determinar-se-á numa fase posterior o consumo anual de água registado numa moradia em Guimarães, e comparar-se-ão os resultados dos investimentos num sistema de aproveitamento de água da chuva em Portugal e na Dinamarca. Ampliando o âmbito para um edifício de escritórios e um edifício escolar, registar-se-á a rentabilidade do sistema. Essa rentabilidade, referindo-se ao número de anos em que o investimento é amortizado, é determinada numa folha de cálculo a partir da conjugação do valor investido com o valor que, anualmente, se consegue poupar com o uso da água da chuva. Concluir-se-á que o factor que verdadeiramente compromete a diferença entre o investimento e a poupança, reside no baixo valor do metro cúbico de água que, em média, se paga em Portugal. O estudo realizado nesta Dissertação revela que um valor mais alto para o preço da água, traduzir-se-ia numa menor diferença entre o investimento e a poupança, do qual resultava um período de retorno significativamente mais baixo. Além disso, os sistemas de aproveitamento de água da chuva são vulneráveis a diversas dificuldades, como as condições meteorológicas, que se traduzem na falta de precipitação nos meses de Verão onde a procura de água é muito superior.

Empleo de la diplomacia preventiva por parte de la Organización de Naciones Unidas en el conflicto de Kosovo de 1998-1999

En el interés de alcanzar la estabilidad y promover el mantenimiento de la paz internacional, la diplomacia preventiva nace como un concepto generador de estrategias encaminadas a actuar antes, durante y después del conflicto. El siguiente documento busca analizar el funcionamiento de los instrumentos de diplomacia preventiva empleados por las Naciones Unidas en la crisis de Kosovo de 1998 y 1999. Esta crisis surgida a raíz del conflicto entre el gobierno serbio y un movimiento disidente, conocido como el Ejército de Liberación Albano-Kosovar, que pretendía darle un perfil más autónomo al territorio y a la población albano-kosovar, reveló una serie de debilidades estructurales que sigue enfrentando este mecanismo en la resolución de conflictos étnicos al interior de los Estados.

A review of existing building benchmarks and the development of a set of reference office buildings for England and Wales

The modern built environment has become more complex in terms of building types, environmental systems and use profiles. This complexity causes difficulties in terms of optimising buildings energy design. In this circumstance, introducing a set of prototype reference buildings, or so called benchmark buildings, that are able to represent all or majority parts of the UK building stock may be useful for the examination of the impact of national energy policies on building energy consumption. This study proposes a set of reference office buildings for England and Wales based on the information collected from the Non-Domestic Building Stock (NDBS) project and an intensive review of the existing building benchmarks. The proposed building benchmark comprises 10 prototypical reference buildings, which in relation to built form and size, represent 95% of office buildings in England and Wales. This building benchmark provides a platform for those involved in building energy simulations to evaluate energy-efficiency measures and for policy-makers to assess the influence of different building energy policies.

Cool Roofs for improving thermal performance of EU office buildings: an investigation for different climates and building layouts

Cool materials are characterized by having a high solar reflectance r – which is able to reduce heat gains during daytime - and a high thermal emissivity ε that enables them to dissipate the heat absorbed throughout the day during night. Despite the concept of cool roofs - i.e. the application of cool materials to roof surfaces - is well known in US since 1990s, many studies focused on their performance in both residential and commercial sectors under various climatic conditions for US countries, while only a few case studies are analyzed in EU countries. The present work aims at analyzing the thermal benefits due to their application to existing office buildings located in EU countries. Indeed, due to their weight in the existing buildings stock, as well as the very low rate of new buildings construction, the retrofit of office buildings is a topic of great concern worldwide. After an in-depth characterization of the existing buildings stock in the EU, the book gives an insight into roof energy balance due to different technological solutions, showing in which cases and to what extent cool roofs are preferable. A detailed description of the physical properties of cool materials and their availability on the market provides a solid background for the parametric analysis carried out by means of detailed numerical models that aims at evaluating cool roofs performance for various climates and office buildings configurations. With the help of dynamic simulations, the thermal behavior of representative office buildings of the existing EU buildings stock is assessed in terms of thermal comfort and energy needs for air conditioning. The results, which consider several variations of building features that may affect the resulting energy balance, show how cool roofs are an effective strategy for reducing overheating occurrences and thus improving thermal comfort in any climate. On the other hand, potential heating penalties due to a reduction in the incoming heat fluxes through the roof are taken into account, as well as the aging process of cool materials. Finally, an economic analysis of the best performing models shows the boundaries for their economic convenience.
