Heat Load Calculation Based on EN 12831 (2003)
Explains the concept of heat load calculation based on EN 12831 (2003).
The heat load calculation provides the energy requirement for heating a building to the specified target temperatures, taking into account the calculation basis selected in each case. Heat generators and heat transfer systems such as radiators or panel heating/cooling systems are then designed on the basis of the determined energy demand.
The following calculation bases are based on the heat load calculation according to EN 12831 (2003):
| Calculation basis | Scope |
|---|---|
| Europe: EN 12831 (2003) | Standard heat load without national adjustment, replaced by the calculation basis Europe: EN 12831-1 (2017) |
| Germany: Supplement 1 to DIN EN 12831(2008) | Standard heat load according to EN 12831 with German supplement sheet 1 (national annex -NA- for Germany), replaced by the calculation basis Germany: DIN/TS EN 12831-1 (2020) |
| Austria: ÖNORM H 7500(2005) | Standard heat load according to EN 12831 with Austrian supplement sheet, replaced by the calculation basis Austria: ÖNORM H 7500-1 (2015) |
| Austria: ÖNORM H 7500-1 (2015) | Standard heat load according to EN 12831 with Austrian supplement sheet. |
| Switzerland: SN SIA 384.201(2003) | Standard heat load according to EN 12831 with Swiss supplement, replaced by the calculation basis Switzerland: SN SIA 384/2(2020) |
| Turkey: TS 2164 (2003) | Standard heat load according to DIN EN 12831 with Turkish supplement sheet. |
| France: NF P 52-612 (2010) | Standard heat load according to EN 12831 with French supplement sheet. |
