Approximate Heat Load

Explains the concept of approximate heat load calculation by means of quick entry.

The heat load calculation provides the energy requirement for heating a building to the specified target temperatures, taking into account the calculation method selected in each case.

In the approximate heat load calculation, there is no need to enter or transfer the individual room components such as walls, windows and doors, as a flat-rate area-related heating load is determined. An area-related energy requirement in W/m² is specified for a room temperature of 20 °C. For rooms with different room temperatures, the area-related energy requirement is automatically adjusted accordingly. The area-related heat load can assumed globally for all rooms or defined individually for each room. Based on the estimated heating load determined, you can, for example, use the heating schematic generator in early planning phases to determine the expected dimensions for shafts and routes or to design the rooms.
