Abstract

On the calculation of the values of heating/cooling loads based on more real state of a building in the city, influences of the sky radiance distribution and the surroundings around the building should be take into account. However they have not been considered to be important factors.<br> In this paper, with the CIE standard general sky and the approximations that have analytic solution, we intend to present a new calculation method of surface irradiance value of the building surrounded by the other buildings. In the development, the accuracy of calculation and the processing time are made much account.
