An analytical method for calculating the sky component of daylight factor as an alternative to the graphical method Danyluk

The complexity of the recommended DBN V.2.5-28-2006 " Natural and artificial illumination " Danyluk graphical method for determining the geometric factor of daylight makes it difficult to use modern computer systems in the design . In contrast, the method proposed analytical method for calculating the coefficient of daylight , on the basis of which it is possible to develop a mathematical model and computer-aided design . An example of the practical use of the developed analytical relationships and verification of the proposed method by comparing the calculation results with similar results for the analytical method Danyluk .
