     the pmv model predicts thermal sensation well in hvac buildings while it predicts a warmer thermal sensation than the occupants actually feel in naturally ventilated buildings. for using pmv model to predict thermal sensation well in a naturally ventilated building, the extended pmv model (pmve) including an expectancy factor (e) and pmv was proposed by fanger. besides, calculations of pmv are too complex to be applied in practice. to obtain simple and applicable correlations, taking qujing of yunnan province, china, as example, a dry season (6-month) field measurement was conducted in a naturally ventilated residential room. based on the collected data, pmve values were calculated by using newton’s iterative method. it is shown that the pmve values approximately vary from −1.3 to 0.20 and the indoor thermal environment is somewhat discomfortable on some cloudy or rainy days. parameters relationships and indoor air temperature gradients (vertical and horizontal) were also studied by using linear regression technique and quadratic polynomial fit technique. numerous correlations with high relativities have been developed. it is convenient to use these results to evaluate the indoor thermal environment in naturally ventilated buildings under similar climatic conditions.
