Abstract：In order to study the spatial distribution characteristics of the solar radiation actually received by windows in vertical walls in different areas of China,based on the Kastrov formula,the calculation methods of total solar radiation and direct radiation of the clear sky in every facing wall was established.The water vapor pressure and altitude were used to fit the parameters of the formula.The horizontal and vertical wall radiation were calculated and the distribution maps were drawn for the residential space requirements in China.The study find that:the spatial distribution of the clear sky maximum radiation amount of 2 hours on the Greater Cold day is influenced by latitude and atmospheric transparency.The Qinghai-Tibetan Plateau is the high-value center and the Sichuan-Guizhou region is the low-value center in China.In the eastern part of China,the amount of solar radiation decreases with the increase of latitude,and the amount of solar radiation received in the maximum 2 hours by the south wall becomes larger with the increase of latitude.Compared with the south wall,the maximum 2 hours radiation received by east and west wall is significantly smaller,could not play the role of sunlight on health and hygiene.The results show that it is feasible to relax the sunshine standard of spacing in the northern area of China,according to the maximum 2 hours radiation quantity received by the south wall of building on the Greater Cold day.
