In this paper,according to the questionnaire and field test,the winter indoor thermal comfort of office buildings in Nanning was analyzed with the index of standard effective temperature ( SET), and the results were compared with those of other domestic regions. The results indicated that 80% people felt comfortable when the temperature ranged from 14. 4℃ to 23. 7 ℃ in SET, and the neutral temperature of thermal sensation was 19℃ in SET. The local residents were less sensitive to thermal environment than those in other domestic regiong. Furthermore, in the residents' acceptable range of indoor thermal comfort, air-conditioning system energy consumption increased with the rising of SET. In addition,if the neutral temperature was taken as the indoor design parameter and was compared with the specified value in national and local standards, the air-conditioning system energy consumption in Nanning would decrease by 6. 4% .%本文以问卷调查和现场测试数据为基础,采用标准有效温度SET探讨了南宁地区办公建筑冬季室内热舒适性,并与国内其它地区的研究进行了比较.研究发现,满意率为80％时的热舒适范围为14.4～23.7℃/SET,热感觉中性温度为19℃/SET;居民对热环境的敏感度较国内其它地区低；在当地居民可接受的室内热舒适范围内,空调能耗随SET的升高而增大；若以热中性温度为室内计算参数,与采用国家和地方标准规定值相比,南宁地区空调系统能耗将降低6.4％.
