ALL SKY MODEL FOR SKY LUMINANCE DISTRIBUTION OF ALL SKY CONDITIONS : A study on classification method of sky luminance distribution Part 3

Anumerical cquation has been proposed by 血 e authors in the previeus papers， It gives the relative values of 山e sky luminance distribution fbr all sky conditions ． Though the numerical equations for the zenith luminance in abso 且 ute value on the various sIandard skies have been pmposed by several researchers to geUhe sky luminance distribution in absolute value ， they do not bring the s山table value fbr the new equation ． A numerical equation on the zenith luminanじe using the same indices as thQse of the newly proposed equation has bcen composed 、 It has made it pessible fbr the sky luminance distribution in absolute value to be estimated by one of the easiest measurable values ，出 e global illuminance ． The 爬 sult of this research work Gonvinced tl 】e authors of its contrihution to 重 he progress and development ofthe prediction technique in the daylit envirenment ． The new equation of the zeni 重 h luminance in absolu に value is introduced ， the process of composing it is explained in detail and the examples of the sky luminance distribution fbr all sky condidons in abso 扈 ute values a∫e il 聖 ustrated in this paper，
