Heat load Calculation According to ISSO 51 and 53(2018)
Explains the concept of heat load calculation according to the Dutch standards ISSO 51 and ISSO 53 (2018).
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 Dutch standards for calculating the heat load assume rooms with a maximum height of four meters. One-family, two-family and multi-family houses are calculated according to ISSO 51, offices and mixed buildings according to ISSO 53. Depending on the selected building type, the correct standard is automatically used for calculation.
