Abstract: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 similar to 150mm for other facade, respectively. Meanwhile, the optimal thickness for concrete exterior walls was in the range of 200mm similar to 300mm Simulation of changing heat capacity proportion showed that the daily temperature difference decreased by 14 degrees C to 5.2 degrees C 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.
