DAYLIGHT RESOURSES ACCOUNTING OF ENERGY COST OPTIMIZATION
The article is devoted to the of conceptual approach development of the problem of energy cost optimization connected with installation of daylight and artificial light illumination. This problem has been suggested to be comprehensively solved based on mathematical equations with regard to the life sphere factors, namely: temperature, light, and air conditions. Energy cost optimization is based on a combined daylight which assures minimum heat loss at maximum light comfort provided in a room. Daylight illumination implies side openings of optimum size and light tubes for top lighting.
