Abstract
The new dwellings which have big window to wall ratio (WWR) in the southern facade, can be considered as direct-gain passive solar house. Although floor heating system has been widely used in the new residential buildings, few studies focus on the coupled effect of the solar radiation and heat storage of the concrete slab on indoor thermal environment during heating period. The object of this study is presenting a thermal performance analysis method about the new dwellings with a hybrid system with floor heating and solar direct gain. In this paper, in order to calculate the solar direct gain through the window which is absorbed by the slab, a simulation is performed for determining the cumulate irradiated concrete slab area during heating period in Dalian, northern China. Furthermore, the coupled effect of heat storage and direct solar radiation on indoor thermal environment is discussed using field survey and theory analysis. A modified index taking into account heat storage and solar radiation for the traditional calculation method of heat load in direct gain solar dwellings with floor heating system are described. The results are very beneficial to improve indoor thermal comfort and reduce energy demand of the buildings.
