ILLUMINANCE, SKY FACTOR AND RELATIVE SOLAR ENERGY AROUND A BUILDING : Design control method considering the quality of daylight in urban open space (1)

Abstract

This study aims at making basic investigation 正 br the f μ ture standard and regulation of building shape considering the qua 璽 ity of daylight arQund the buiIding ． F 孟 rstly ， we s玉 mu 生 ated sky factor and relative muminance i ' n cLoudy conditiQn ． Comparing their levelS ， it was 葦 bund that sky factor could be representative index of the brightness in urban open space ， Secondly ， the relative solar energy in sunny condition and sunsh 孟 ne duration were calcu 正 ated ． A 且 though the distribution of sunshine duration ha5 wider spread toward east and wes 転 these impacts spread to north intensively in the distribution of relative solar energy ・
