Abstract(s)
A presente dissertação destinada à obtenção de grau de Mestre enquadra-se na recente temática Nearly Zero Energy Building (NZEB), consistindo no estudo de um edifício de serviços, sediado na cidade de Setúbal, com o objetivo de tentar a sua convergência para o conceito NZEB. Avaliou -se o edifício e foram propostas medidas de melhoria do conforto térmico bem como a redução dos consumos energéticos.
Inicialmente realizou-se a caracterização atual do edifício de modo a recolher toda a informação necessária para modelação em três dimensões (3D) recorrendo ao software Google Sketchup, sendo posteriormente efetuada uma primeira análise energética do seu estado atual, com recurso ao software EnergyPlus.
Numa segunda fase foram avaliadas estratégias destinadas ao melhoramento da eficiência energética do edifício e mais uma vez recorrendo-se ao acoplamento do software Google Sketchup com o modelo EnergyPlus, procedeu-se à simulação individual de cada medida proposta e numa segunda fase, a simulação com as medidas em simultâneo, de modo a comparar os consumos energético face à situação atual do edifício. Com base nos resultados obtidos, verificou-se o consumo energético bem como a poupança anual resultante da implementação de cada medida. Foi avaliada a viabilidade prática de execução de cada uma das medidas de melhoria do comportamento energético do edifício, com base na análise custo-benefício.
Abstract: The present dissertation aimed to obtaining a master degree in Civil Engineering fits in recent Nearly Zero Energy Building (NZEB) concept, consisting of the study of a service building located in the city of Setúbal in order to try its convergence to the NZEB concept. The building was evaluated and measures to improve the thermal comfort as well to reduce the energy consumption were proposed. The current characterization of the building was initially held in order to collect all the necessary information for modeling production in three dimensions (3D) using the Google Sketchup software; on a first phase an energetic analysis of the current state of the building was perf ormed using the Energy Plus software. Strategies aimed at improving energy efficiency of the building were evaluatedon a second phase and each individual measure was evaluated using the Energy Plus software. A final simulation with all the improvement measures was developed in order to compare the expected energy consumption with the current situation of the building. Based on the results the energy consumption as well as the annual savings resulting from the implementation of each measure were compared. The practical viability of each implementation measure in order to improve the energy performance of the building based on a cost-benefit analysis was assessed.
