    Abstract: Air conditioning systems are definitely necessary and vital components in modern construction and it is not possible to keep heating balance and quality of indoor air of high-rise buildings and rooms with particular application such as server rooms without such systems. The importance of this issue caused association of major part of energy consumption in buildings to their air conditioning systems hence, it is required to focus on frugality methods in energy consumption. This study aimed on presenting an analysis of effect of radiation energy on air transfer channels in buildings consisting central air conditioning system in order to use obtained results and reduce heating energy consumption. Climate features of Tehran urban region have been considered as background presumption to make this study more practical.
