Optimization of Building Envelope Thermal Design for Passive Solar House
Optimization design of building envelope-integrated collectors plays an important role in reducing energy consumption and improving thermal comfort. Take a passive solar house for an example, optimization design principles for passive solar house were proposed by simulation. Simulation results by changing envelope insulation thickness showed that the optimal thickness was between 30mm and 70mm for south wall, and 70mm~150mm for other façade, respectively. Meanwhile, the optimal thickness for concrete exterior walls was in the range of 200mm~300mm. Simulation of changing heat capacity proportion showed that the daily temperature difference decreased by 14oC to 5.2oC as the proportion increased doubled. However, considering the building initial investment, the arrangement of thermal mass should be determined by the building type and energy demand.
