O objetivo desta dissertação consiste em avaliar se um grande edifício de serviços, sediado em Vila Nova de Gaia, poderá ser convertido ou possuir uma forte tendência para um Edifício com Necessidades Quase Nulas de Energia (NZEB), como vem enunciado no Decreto-lei 118/2013. A Diretiva europeia (EPBD) define NZEB de forma pouco clara, permitindo que cada país estabeleça os seus objetivos. Portugal não estabeleceu, até ao momento, uma quota-parte de energias renováveis que deve integrar um NZEB, ou um indicador numérico limite para utilização de energia primária(expresso em kWh/m2.ano), como a EPBD obriga no último caso.
O edifício em estudo foi modelado no Revit, procedendo-se à simulação energética com ferramentas do próprio programa. Analisou-se, simulando vários cenários de reabilitação e medidas interventivas, sendo posteriormente avaliada a sua viabilidade económica. Com a promoção de um conjunto de medidas viáveis, chegou-se a um valor de utilização de energia primária de 69 kWh/m2.ano, possibilitando afirmar que o edifício em estudo converge para NZEB, à luz de alguns indicadores numéricos já estabelecidos por outros países da União Europeia.
Abstract: The aim of this dissertation is to assess whether a large building services, based in Vila Nova de Gaia, can be converted, or have a strong tendency for buildings with requirements of Nearly Zero Energy Buildings (NZEB), as is set out in Decree Law 118/2013. The Energy Performance of Buildings Directive (EPBD) sets NZEB in an unclear way, allowing each country to establish its goals. Until now, Portugal has not established the share of renewable energy that must integrate a NZEB, or a limit numeric indicator for use of primary energy (in kWh/m2.year) as the EPBD requires in the latter case. The building under consideration was modelled in Revit, as well as the energy simulation, with the program's own tools. The analysis was made by the simulation of multiple scenarios of rehabilitation and interventional measures, and subsequently assessed their economic viability. With the application of multiple effective measures, the value of primary energy use accomplished was of 69 kWh/m2.year, making it possible to say that the building at study converges to NZEB, in the light of some numerical indicators established by other European Union countries.
