CUMPLIMIENTO DEL ESTÁNDAR PASSIVHAUS MEDIANTE SIMULACIÓN EN LA FASE DE DISEÑO. APLICACIÓN EN LA REGIÓN DE MADRID.

Abstract

The aim of this paper was to reduce the overall consumption of the building. Besides getting to meet Passivhaus parameters in addition to improving indoor comfort. The space heating and the cooling loads, instead, are computed, on an hourly basis, by the building energy software tool TRNSYS, version 17, by accounting for the actual climate of the considered location. In this work we have analyzed the effect of different passive strategies. This software has been used on a set of terraced houses located in Madrid (Spain). Results show that are possible to get a lower demand up to 63% comparing with initial project. It is noted that a bypass, the extra ventilation and shading have a marked effect on the cooling demand. The factors that are more affecting the heating demand are the exchanger performance and windows type. The greatest reduction occurs on cooling demand, up more than 80%, and the heating is decreased by 37%.
