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 30 mm and 70 mm for south wall, and 70 mm ∼ 150 mm for other facade, respectively. Meanwhile, the optimal thickness for concrete exterior walls was in the range of 200 mm ∼ 300 mm. Simulation of changing heat capacity proportion showed that the daily temperature difference decreased by 14 °C to 5.2 °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.
