5.2.5. Door<br>

### 5.2.5. Door

The “Door” component cannot stand alone – it may only be placed on a wall to which it is assigned, and its data is displayed in the lower part of the wall data table. It is taken into account when heat loss calculations are done in Instal-heat&energy – just like in the case of a wall and window, the door has a partition structure assigned, and the surface area of the door is subtracted from the calculated surface area of the wall in which the door is installed.

To place a door in a wall, select it from the “Components” toolbar and click on the wall axis at a selected point. You can move the door along the wall or reorient it by dragging the square with arrow displayed after marking the door.

Button on the “Components” toolbar:

“Door” component data:

Width [m]

Numerical field. Width of the door, measured along wall axis.

Height [m]

Numerical field. Height of the door.

Drawing type

Selection field. Drawing type that determines whether the door is to be drawn as a single-leaf door (single) or a double-leaf door (double). You can make your selection from a list of available door appearance on the plan view of storey.

Partition structure type

Selection field. Type of partition structure. When heat loss calculations for rooms and specification of partitions is done in Instal-heat&energy, then this is a selection field where you can select a pre-defined partition from a list. If a type has already been assigned to the door in Instal-heat&energy, then its name is automatically displayed in the graphical editor and the appropriate U0 coefficient is displayed in the field below.

U0

Numerical field. Coefficient of heat transfer across partition. When heat loss calculations for rooms and specification of partitions is done in Instal-heat&energy, then this field cannot be modified. It is automatically filled in for the partition type selected from list.
