VALIDAÇÃO DE PROTÓTIPO DE EDIFICAÇÃO RESIDENCIAL PARA SIMULAÇÃO E CLASSIFICAÇÃO DE VIDROS

Abstract

This article presents the validation of an architectural prototype to run computational simulations to classify window glazing systems according to their thermal performance, for three Brazilian climates. For this, two models were defined for computational simulation - a prototype that represents a room of a residence and a real residence. After that, 14 glass types were selected and characterized for simulation. In total, 210 simulations were performed in EnergyPlus software. The annual energy consumption for heating and cooling provided by each glass was extracted. Then a rating was developed of the energy savings provided by each glass for heating and cooling in a performance ranking. This classification was elaborated for both building models and then compared. The graphs showed that for cooling energy estimation the prototype follows a trend in relation to the real building, presenting good R² values (0.9397 for Salvador, 0.9919 for Sao Paulo and 0.9948 for Porto Alegre). In case of heating energy consumption this does not happen, R² values are lower (0.7256 for Porto Alegre and 0.7356 for São Paulo). Because of this the research will continue. More simulations and tests will be carried out to arrive at an ideal model.
