Abstract

Taking office building in Chongqing as an example analyzes the effect of increasing building airtightness on energy consumption and indoor temperature. The simulation results show that the indoor temperature will increase as the airtightness level improves in summer, but reduce the comfort degree and increase air-conditioning load. In winter, it shows the opposite tendency. Furthermore, the cumulative heating load in the transitional season gradually decreases with the increase of the airtightness level, but the cooling load shows the opposite tendency. Therefore, during the transitional season, people can use the nature ventilation to take away some of the excess heating and humidity load.
