Based on the observational weather data, the typical meteorological year (TMY) is developed for 360 Chinese locations. Temperature and solar radiation for air-conditioning design for these locations are also suggested on frequency analyses. The author divided China into seven regions according to the heating and cooling degree-days. Influence of climate change on air-conditioning load is discussed. Moreover, the thermal design code for Chinese residential houses is compared to that of Japan, and the differences between China and Japan are clarified.
