Abstract

This article presents a proposal to evaluate cooling demand and passive cooling capacity using natural ventilation in social housing. The proposal is founded on EN ISO 13790:2008, which uses a semi- dynamic calculation method. The dwellings evaluated have double casement windows in the two main facades, which are oriented N-S, E-W, NW-SE and NE-SW. Two possible internal distributions were tested: poorly-connected and well-connected. The locations evaluated have a variety of climates: from the northern deserts to the weather of central and southern Chile with more defined seasonal variability. The cities included in the study are: Arica, Iquique, Antofagasta, La Serena, Valparaíso, Concepción, Valdivia and Puerto Montt. The results show that cooling demand is present in the majority of the locations analyzed and the average capacity for heat evacuation by natural ventilation is between 20% and 80% of this demand, thereby demonstrating the usefulness of breezes for building and city cooling in Chile.
