Ventilation

In the Ventilation module, the required air volumes for residential buildings and for the rooms of non-residential buildings are determined. When determining the air volume, aspects of building physics, ventilation and building technology as well as hygiene are taken into account in accordance with standards. Depending on the ventilation system selected, the mechanical supply and/or extract air volume flows are derived from the air volumes determined. These volume flows can then be transferred to the CAD program where they can be used for duct dimensioning and fan design. In addition, the supply and/or extract air flows are synchronized with the heat load module depending on the selected heat load standard and taken into account in the load calculation. For residential buildings, you can create ventilation concepts for the ventilation zones of the project and then carry out the design in the Domestic Ventilation module.

Different calculation methods are available for determining the air volume for residential buildings and for the rooms of different types of non-residential buildings. You can define two calculation methods, which are assigned to all room types in the project by default. The volume flow rate of the calculation method with the highest value is always used as the required air volume for a room. If required, you can define calculation methods that differ from the standard calculation methods for the individual room types. You can create exceptions to assign calculation methods that differ from the room type to individual rooms or groups of specific rooms. This makes it possible to plan individual rooms or groups of rooms within a project according to different standards or guidelines.
