Abstract
This paper shows a production method of typical annual weather data (TWD9302). TWD9302 is consist of two datasets. One contains ambient air temperature, absolute humidity, wind direction, wind velocity, nocturnal radiation, illuminance and irradiance at intervals of one minute.The other contains modified data at intervals of 30 minutes by sky luminance distribution and sky radiance distribution. Long-term observation data had been gained in Chofu-city, Tokyo, Japan from 1993 to 2002. TWD9302 makes it possible to improve the precision of illumination simulation and cooling/heating load calculation with taking sky luminance distribution, illuminance, sky radiance distribution, irradiance and night radiation into consideration.
