Abstract

This investigation facilitates the design of passively heated and cooled houses in a mediter-ranean climate with new and simple design tools and recommendations based on thermal simulations with a new TRY for central Chile. First, the basic thermal characteristics of house designs were calculated according to European building codes, which are similar to, but more complete than local codes. Neces-sary empirical parameters for passive heating and cooling were determined for the local climate condi-tions with special simulations. Complementary models for passive design strategies were included. In winter, the effective gains-to-loss ratio permits a good estimation of the mean daily degree - hours of cold in winter in a passive house with free-floating temperatures according to empirical formulae, which were prepared and calibrated with extensive thermal simulations. In the same way, the new excess gains-to-loss- and-capacity ratio permits the easy estimation of the mean daily degree - hours of heat in summer (overheating). Moreover, the simulations permitted a better understanding of the crucial thermal design characteristics, which is resumed in the design recommendations. This way the investigation supports the design of sustainable buildings, which offer good thermal comfort based on renewable energy.
