This paper shows the production method of standardized annual weather data(SWD9300). SWD9300 consists of two datasets. One contains ambient air temperature, absolute humidity, nocturnal radiation, illuminance and irradiance at intervals of one minute. The other contains the modified data at intervals of 30 minutes by sky luminance distribution. The long-term observation data had been gained in Chofu-city, Tokyo, Japan from 1993 to 2000. SWD9300 makes it possible to improve the precision of the illumination simulation and cooling/heating load calculation with taking sky luminance distribution, illuminance and night radiation into consideration.
