ABSTRACT
The research is to explore the changes in solar heating buildings under energy-saving structural design. This paper analyzes the changes in solar heating buildings under energy-saving structural design by constructing a numerical simulation method. It mainly studies the effects of the space temperature of the house, different thermal insulation methods, and wall thermal resistance on solar heating buildings. The energy-saving structural design mainly includes expanding the area of exterior windows, increasing heat retainers, adopting energy-saving walls, and improving the building envelope. The results show that after the energy-saving structural design, the indoor temperature of the solar heating building after the renovation has been greatly increased, with an average increase of about 6 °C. Compared with the external insulation and internal insulation modes, the solar heating building under the sandwich insulation mode has the best effect, and the room temperature increases the most. Also, it shows that the east wall, west wall, and north wall of the building are increasing the energy saving per unit area of the wall as the wall thermal resistance increases. The difference is that the increasing range of the north wall has significant advantages over the east wall and the west wall. The energy-saving structural design for solar heating buildings under the numerical simulation method has significantly improved the utilization efficiency of solar energy. It reduces the consumption of traditional fossil resources and improves the quality of the environment. This paper’s research has a positive effect on subsequent research.
