Résumé

Since the heat wave of 2003, summer thermal comfort in buildings and more particularly in residences for the elderly has become in France one of the major concerns of building owners. Hence, they have been requesting finer thermal simulation studies. Within the framework of a care home project for dependent elderly people, two ventilation systems have been studied: a double-flow system with possible adiabatic indirect evaporative cooling and a buried-pipe system coupled to a double-flow-type blowing network. The building model studied has been defined using TRNSYS software. Simulations were carried out using the annual weather data file of Toulouse (south of France). The performance analysis in terms of energy consumption and thermal comfort (evaluated by a number of hours of overheating) of the double-flow and buried-pipe systems is carried out over the whole year and seems favourable compared to the results of a basic simple-flow ventilation system.
