| Summary: | It was divided into different modes according to the level of set point temperature (SPT): SPT ≥ 26 °C and SPT < 26 °C. To study behavioral adaptation of different set point temperature modes in office buildings with split air conditioners, a summer field survey was conducted in Zhengzhou and Jiaozuo, China. The results showed that the clothing insulation in high SPT mode was primarily affected by age, whereas the clothing insulation in low SPT mode was influenced by age and indoor temperature. The clothing insulation in high SPT mode was significantly lower than that in low SPT mode, and the air velocity and air movement sensation of subjects in H mode were significantly higher than those in L mode. 1 °C rise in Top could lead to 0.026 m/s increase in air velocity in high SPT mode, but the air velocity in low SPT mode had no relationship with indoor temperature. People’s behavioral adaptation enthusiasm in high SPT mode was greater than that in low SPT mode. The energy consumption can be saved by about 14.8% after considering the adjustment of people’s clothing.
