Projeto de Edificação Residencial Unifamiliar para a Zona Bioclimática 2 com Avaliação Termo Energética por Simulação Computacional

Abstract

The present work is a proposal of an architectural project for a residential construction for bioclimatic zone 2, developed from recommended bioclimatic strategies of passive conditioning for places of great climatic variation, as Pelotas- RS, in order to optimize thermal and energetic performance. After development of base case the project was evaluated by computational simulation, on basis of parameters and definitions of RTQ-R (2010), using softwares DesignBuilder and EnergyPlus. Project thermal performance was evaluated based on energy flows and in degree-hours of discomfort relating to the operative temperature for environments of prolonged permanence. Energetic performance of envelope project was evaluated acording procedures of the RTQ-R. Later there were proposed modifications in base case with the aim to improve thermal and energetic performance, which once again was simulated and evaluated. The results of simulations of modifications in base case, mainly due to isolation of the construction envelope, resulted in a very significant improvement in winter. In case of evaluations made according to RTQ-R, numerical equivalent of envelope of the independent housing unit for base case resulted in C and with the modifications proposals it raised to A, with both climatic data.
