Analysis of selected input data impact on energy demand in office building - case study

Abstract

In the building designing process special attention should be paid to energy calculations - with analysis of different input data low energy or passive house can be obtained and decision of which parameters can or cannot be changed may be made. The following input data was analysed: shape factor A/V, glazed area, internal heat gains, air tightness, efficiency of heat recovery. The results show that the input data for the energy calculations are crucial for the obtained result.
