Research on Energy-saving Design Method of Building Envelope in Hot Summer and Warm Winter Area

Abstract

Since the beginning of the 21st century, with the rapid economic growth, energy pressure has continued to increase, and China’s energy consumption has doubled and become one of the main energy consumers. Building energy consumption accounts for a large proportion of total energy consumption. Therefore, building energy efficiency is the top priority of green building development. By improving the thermal performance of the building envelope, reducing the building’s energy consumption and dependence on artificial cold and heat sources, it has become the current research focus. This paper studies the energy-saving design methods of building envelopes in areas with hot summers and warm winters. It mainly analyzes the energy-saving methods of exterior walls in the envelopes, proposes the development of energy-saving technologies that adapt to local climate characteristics, and concludes the overall building shading structure system is the key to energy-saving design in this area.
