Estimating natural-ventilation potential considering both thermal comfort and IAQ issues

Based on the previous study by Yang et al., the authors developed a revised model to estimate the potential for natural-ventilation considering both thermal comfort and IAQ issues for buildings in China. That model differs for two aspects : indoor air temperature varies synchronously with the outdoor air rather than staying at a constant value as assumed by Yang & al., and thermal comfort evaluation index is integrated into the model. The NVP values are obtained for a single building in four different representatives cities of China (located in different climates) and then compared with the previous work of Yang & al. The results are quite different. Their conclusion are presented.
