General Information

When transferring the rooms from the CAD model, LINEAR Building applies the general room type. In domestic ventilation, a room type according to DIN 1946-6 is derived from the general room type. If required, a room type can be selected manually at this point without changing the general room type.

Number/Name

Shows the number and name of the room.

Geometry, Room Type acc. to DIN 1946-6

Room selection

Shows the room type. Clicking allows you to select a different room type.

Length/Width/Area/Volume

Displays the rooms dimensions. Click on to recalculate the dimensions.

Room with External Window

Indicates whether there is an exterior window in a room. By default the program assigns an exterior window to all rooms. Deactivate the option if there is no exterior window in a room. Rooms without windows have higher minimum volume flow rates and design volume flow rates. If the building has been transferred from CAD, or the room components of the room have been entered manually, the program automatically activates or deactivates the setting Room with Exterior Window, depending on whether an exterior window is included in the room components or not.

Room with Room Air Dependent Heating System

Indicates whether a room air-dependent fireplace is present in a room. Room air dependent heating systems are for example gas boilers, boilers with atmospheric combustion, coal, wood or oil ovens, which take the necessary combustion air from the installation room. In case of mechanical or fan-assisted ventilation, a room-air-dependent fireplace affects the infiltration calculation and the outside component air outlet are designed with a pressure difference of 4 Pa so as not to affect the operation of the combustion system. Without a room air dependent heating system, the exterior component air outlets are designed at a maximum of 8 Pa in order to avoid flow noise or the effect of unacceptably high forces on the doors. By default, the setting Room with room air dependent heating system is deactivated.

Room for drying washing

Indicates whether a room is used for drying laundry. Extract air rooms in which laundry is dried are designed with an extract air volume flow rate of 40 m³/h.

Ventilation Components (Informative)

Displays the ventilation components of the room. Non-ventilated rooms and overflow rooms have no ventilation components.

View Room Components (Only Informative)

Opens a table with the detailed component data of the room components of the room instead of the diagram of the selected room. The table only contains component data if room components exist for the rooms at room level. When a building is imported from a CAD program, such components are automatically detected and displayed here. You can only modify the component data in the Heat Load or Cooling Load modules.
