Study on Energy-saving Design of Immigrant Residential Buildings in Midwestern Ningxia

Abstract

Based on the investigation of the indoor thermal environment of rural immigrant residential buildings in Shapotou District, Zhongwei City, Ningxia Province, the indoor thermal environment is tested and analyzed. Combined with the local geographical conditions and economic development, the external envelope structure is optimized, and the energy-saving transformation scheme of the envelope structure is put forward. The energy consumption analysis model is established by DeST software, The energy consumption of immigrant residential buildings before and after reconstruction is simulated. The results show that the maximum indoor natural temperature of the reconstructed building in the coldest month is increased by 6.45°C, the minimum temperature is increased by 4.51°C, the average temperature is increased by 5.57°C, and the building energy efficiency is increased by 63.4%. The cumulative load reduction of four immigrant villages in one year is converted into standard coal of about 3900t. The results provide a theoretical basis for improving the indoor thermal environment and reducing building energy consumption of immigrant residential buildings, and provide a reference for the development of residential buildings suitable for the local climate.
