About General Heat Load Data

Explains the concept of general heat load data in the context of heat load calculations.

In the General heat load data section you enter basic settings for calculating the heat load of your building. All settings made here are valid for your entire project. Some settings, such as the ventilation system, can be modified in the respective structural level (building unit, ventilation zone, room) deviating from the values set here.

You start with the selection of the calculation method and the input of building and climate data. In the next step, you define the shielding class, the building mass and the ventilation system. By selecting the safety class according to ISSO 51, you determine the safety factor for the calculation of heat loss from room components that adjoin rooms of another building unit in the project. Depending on the selected standard, you can also define minimum temperatures for unheated building units and heat transfer systems.
