COMFORT IN HOT SEASON IN A MEDITERRANEAN BUILDING. A ZONAL APPROACH

摘要

In the Mediterranean countries, where the active solutions of air-conditioning must be avoided, natural ventilation allows improvement of indoor comfort which is generally critical in hot season, and reduction of building cooling loads. A three-dimensional zonal model for calculating temperature fields and airflow distributions inside unconditioned buildings was developed. Its coupling with a thermal comfort model allows to evaluate the thermal quality of the ambiance by the prediction of a comfort note. This paper presents the use of this model to study the effect of the night natural cross-ventilation on the temperature field and the air velocity distribution inside an unconditioned Tunisian building, and the evaluation of the thermal sensation of its occupants.
