Effects of three passive techniques on thermal performance of a building in Marrakech region

This study deals with dynamic simulation of a villa type house located in Marrakech region (Morocco) which was designed as a green house with several passive systems, techniques and local materials. Three of these techniques were examined: hemp insulation, hollow core slab and high inertia. Simulations were carried out during one year using TRNSYS software with the multi-zone model. The effects of integrating these passive systems and materials on air temperature in the building were analyzed for two configurations: real house and standard one. The latter refers to materials commonly used in Marrakech region. The results indicate that combining all of these passive techniques lowered the cooling load by 76% and the heating load by 62%.
