Abstract
Cooling load calculations are essential in sizing air conditioning system equipment. In designing energy, efficient and renewable energy sourced cooling systems for buildings, it is important to have the exact values of cooling loads and seasonal cooling demands of buildings. In this paper new assessment method for more precise determining of cooling loads and seasonal cooling demands of residential buildings are developed, which are necessary for right solutions of cooling efficiency problems. Comparing to the method of ASHRAE, example and other methods it provides more correct results. Application of suggested method provides better accuracy in assessment of cooling loads especially for seasonal aspects, as they take into account the impact of more factors.
