Abstract: Today, we have measured energy consumption or used data from utility bills and standard weather normalization methods (heating degree days (HDD)) to easily calculate the energy performance certificate (EPC) for existing building. However, normalization methods must be upgraded to be more accurate for weather. This study uses analytical model for weather normalization of air handling unit heating consumption. The models derived from measurements of the ventilation system in a real building were conducted and the normalization aspects were analysed. A new analytical weather normalization calculation method for ventilation heating is compared with heating degree day normalization.

Description: \| openaire: EC/HE/856602/EU//FINEST TWINS Funding Information: However, it should be considered, that these analyses do not include possible frost protection and defrosting energy use. Therefore, future studies should include to the analysis some frost sensitive heat exchangers as for example, cross-flow plate heat exchanger. Furthermore, future studies should be extended to building level as in actual case, most buildings have data only for whole ventilation heating.
