A recuperação e reforço de estruturas de concreto armado estão cada vez mais frequentes no Brasil, devido, principalmente, ao envelhecimento das estruturas construídas nas décadas de 60 e 70 do século XX, as quais estão prestes a atingir seu tempo de vida útil. Somam-se a isto, fatores como o uso de concretos com baixa resistência, falhas de execução, além do uso inadequado e da falta de manutenção. Devido a esses fatores que a sociedade deve se preocupar em reforçar e/ou recuperar essas construções, evitando assim, demolições das mesmas e até mesmo evitar acidentes fatais. Este trabalho apresenta um estudo de caso, que visa a recuperação de um edifício, que se encontra abandonado há cerca de duas décadas na cidade de Rio Branco, Estado do Acre. Atualmente, existem várias técnicas de reforço de estrutura de concreto armado. Tais como: reforço por meio de encamisamento de concreto armado, complementação ou reforço com adição de armadura, reforço com aplicação de chapas e perfis metálicos, reforço de pilares com polímeros reforçados com fibra de carbono (PRFC), dentre outras. Neste trabalho, o método adotado para a recuperação foi o reforço por meio de encamisamento de concreto armado. E para uma melhor compreensão da metodologia adotada o trabalho apresenta também detalhes da configuração do reforço adotado, detalhe construtivo e procedimentos executivos do método adotado. Além, das envoltórias mostrando os esforços atuantes e resistentes do antes e depois do reforço.

Confirming the Brazilian tendency in the field, the multifamily vertical condominium habitats in Natal are defined as buildings with three or more floors which have been an increasingly used solution. In the mentioned project, the connection between the projectarchitects and the user/ buyers are spread out, by which the first people conceive the realestate property as a creation for the market and not the individual client in specific. Such situation along with technical and financial limitations of the project lead to the adoption of standard solutions to be utilized by clients with different profiles. Besides that, there are various legal and urban parameters by the City Director Plan showing elements of great influence in the final solution adopted by the mentioned edifices. Moving to this subject in general, this project is focused on the case study of the Ed. Ville de Montpellier, having as a base of Post Occupancy Evaluation (POE), considered an efficient tool to analyze and keep up with the progress of the construction of the building, including technical approvals, the application of surveys with the local residents and the creation of informal interviews. The data shows that with time some items that initially motivated the acquisition of the realestate property (with a social common area) move to being less valued, and that the residents quickly alter the pre constructed space, thus seeking to alter the property in a more personal and conforming manner. The possibility of a new emphasis for projects on the mentioned space should also be in discussion, the created project calls for the attention of projected conceptual aspects and interdependence within project and construction which permits the indication of some recommendations for the projection of multifamily residential buildings within the studied realm

It is presented the analysis of a retaining wall designed for the basement of a residential building, located in Natal/RN, which consists in a spaced pile wall, anchored by tiebacks, in sand. This structure was instrumented in order to measure the wall s horizontal movements and the load distribution throughout the anchor fixed length. The horizontal movements were measured with an inclinometer, and the loads in the anchors were measured with strain gages, installed in three places throughout the anchor fixed length. Measurements for displacement were done right after the implementation of each stage of the building and right after the conclusion of the building, and the measurements for loads in the anchors were done during the performance test, at the moment of the locking off and, also, right after the conclusion of the building. From the data of displacement were obtained velocity and acceleration data of wall. It was found that the time elapsed on braced installation was decisive in the magnitude of the displacements. The maximum horizontal displacement of wall ranged between 0,18 and 0,66% of the final depth of excavation. The loads in the anchors strongly reduced to approximately half the anchor fixed length, followed an exponential distribution. Furthermore, it was found that there was a loss of load in the anchors over time, reaching 50% loss in one of them

This research refers to the production of green buildings, defined, mainly, based on the use of sources of alternative energies, smaller emission of pollutant, use of recyclable materials, systems of recycling of the waters, maximization of the natural illumination, preservation of green areas or native, and appropriate quality of the internal air. From the conception of those buildings, it appears the needs of evaluating them, creating the methodologies for the evaluation of environmental performance of buildings. In that way, this work can be divided in two moments: the first one when it identifies the methodologies for the evaluation of environmental performance for buildings existents in the literature, defining their categories, criteria and sub-criteria to be appropriate to the reality of the Brazilian Northeast; and the second one when starting from the analysis of the systems of existent evaluation. It defines a methodological base and it generates a new evaluation system, denominated MEDACNE (Methodology of Evaluation of Environmental Acting for Construction in the Northeast). In that moment, the process of framing of the section of the building site is verified under the maintainable optics, stimulated mainly by the pressures of the society - conferences, protocols and agreements. Finally, the proposed methodology was applied in a case study, a residential building, called Maria José Gurgel , located in Natal-RN, Brazil, for its validation. This methodological proposition should increase the patterns environmental places for the production of new buildings, and it will be a reference guide for architects, engineers and planners to develop their constructions considering the criteria of the sustainability. This study made use of bibliographical research in books and specialized magazines and the analysis of the data was realized in an interpretative way

Devido aos seus hábitos de voar alto e se abrigar em folhas de palmeiras, há poucos registros na literatura sobre o morcego Diclidurus scutatus Peters, 1869. No Brasil, essa espécie é conhecida somente na região Norte e o presente estudo descreve sua primeira ocorrência na região Sudeste. O morcego foi encontrado morto no parapeito da janela de um apartamento do nono andar, em um edifício residencial, na área urbana da cidade de São Paulo, estado de São Paulo. Provavelmente esse morcego devia viver na Serra da Cantareira, um fragmento da mata Atlântica, próximo da cidade de São Paulo.

Com o crescimento populacional tem-se verificado um aumento exagerado no consumo energético global, no qual Portugal é também um exemplo. O recurso à utilização de combustíveis fósseis como fonte para satisfazer as necessidades adicionais de energia, tem vindo a contribuir para uma aceleração do fenómeno das alterações climáticas, que promovem efeitos negativos sobre o planeta, onde uma das suas mais sentidas consequências é o aquecimento global. O sector dos edifícios, desde a construção à utilização, apresenta um elevado consumo de energia final, do qual metade corresponde ao sub-sector residencial. Este facto torna importante que se equacionem alternativas, e que sejam adoptadas medidas que possam contribuir para alcançar uma melhoria da eficiência e do desempenho energético dos edifícios. Os edifícios habitacionais, por terem o seu desempenho energético na fase de utilização muito dependente do comportamento dos utilizadores, são aqueles que maior consumo energético apresentam. Neste contexto, torna-se importante que sejam desenvolvidas iniciativas que visem melhorar o seu desempenho e que possam ver adoptadas medidas de reabilitação energéticas de modo passivo e activo. A procura por um balanço próximo do zero, entre necessidade de consumo, e potencial de produção local de energia, permite que se possam adoptar soluções alternativas de produção de energia, focadas em fontes renováveis. Contudo, é importante que as medidas a implementar, tanto nos novos como nos edifícios já existentes, tenham sempre como principal finalidade a melhoria das condições de conforto no seu interior e um elevado nível de desempenho energético. A introdução de soluções passíveis de reforço de isolamento, devem decorrer da introdução de soluções que podem ter auxílio na ferramenta da certificação energética como suporte. Porém, as soluções de complemento para o equilíbrio do balanço entre consumo e produção podem ser auxiliadas pela introdução de sistemas activos de produção de energia, impondo-se, no entanto, que ocorra um claro benefício económico da análise custo-benefício dos investimentos associados. A presente investigação procura, estudar o nível do contributo que pode resultar da introdução de um sistema solar fotovoltaico, num edifício de habitação unifamiliar e determinar o correspondente resultado para o equilíbrio do seu desempenho energético e nível de eficiência energética.

Neste trabalho faz-se um estudo sobre o conceito edifício inteligente, onde se incluem as tecnologias que permitem a gestão de todos os recursos habitacionais (domótica). Para melhor compreender o assunto, inicialmente define-se o conceito edifício inteligente de acordo com várias instituições e personalidades, seguido de uma breve revisão histórica e o levantamento dos casos existentes a nível internacional. Faz-se uma análise sobre as funções da domótica, e descrevem-se os principais protocolos utilizados em automação residencial, destacando aspectos gerais sobre os mesmos, como praticidade, vantagens e desvantagens. Neste contexto, é proposto um projecto de automação residencial utilizando o protocolo X-10, no qual são abordadas algumas técnicas, que permitem fazer a gestão inteligente da energia, e o controlo de segurança. Este conceito tem sido muito aplicado internacionalmente, apresentando como uma boa solução para a sustentabilidade dos edifícios.
