摘要：In the present scenario, one of the major issues being faced in all the industrial as well as institutional organizations is energy conservation. Conserving energy is a significant phenomenon for preventing the environment and for reducing the energy expenditure met by the organizations. Therefore, it is important to analyze the heat stress of the regional climate and select the appropriate building energy-saving design method to reduce the energy consumption. Changes of the indoor temperature of the residential buildings before and after the renovation during the whole heating season were analyzed based on 16 effective measuring points of the building indoor temperature. The results show that the indoor temperature of the building that has not undergone energy-saving renovation is significantly lower than that of the building after renovation. The average temperature of the building before the renovation was 20.1 °C, and the average temperature of the building after renovation was 22°C, both of which were higher than designed 18°C.
