With the rapid development of building technology,transparent envelope is more and more widely used,which makes the indoor environment of buildings more and more affected by solar radiation.However,the effects of solar radiation are not included in the PMV model.The Corrected Predicted Mean Vote (CPMV) model considering solar radiation was previously proposed and verified in northern China.In order to expand the applicability of the CPMV model to the hot summer and cold winter (HSCW) zone of southern China,a field study was conducted in an office building in Nanjing.A total of 686 valid questionnaires were recovered during the surveys in two summers in 2019 and 2020.The results show that the eval-uation value of CPMV is highly consistent with the actual thermal sensation vote (TSV) when the corrected operative temperature is below 30 ℃.However,when the corrected operative temperature is above 30 ℃,the CPMV value is higher than TSV,because it underestimates the tolerance of human body to the hot environment in Nanjing.The thermal neutral temperature is 26.12 ℃ (CPMV) and 26.28 ℃ (TSV) respectively,which is higher than that in winter and sum-mer in northern China.This study fills the blank in the application of CPMV model in southern China.The CPMV model can accurately evaluate the thermal comfort of indoor environment affected by solar radiation,which is worthy of promotion and application to other types of buildings and areas.
