“Curved wall” component data:

Length within axes [m]

Numerical field. Length of wall within axes. This field may be filled when inserting a wall (after marking one end of the wall). Then the entered length is retained in the drawing. A value in brackets indicates length read from the drawing.

Angle

Numerical field. Angle in relation to X-axis. This field may be filled when inserting a wall. Then the entered length is retained in the drawing. A value in brackets indicates angle read from the drawing.

Thickness [m]

Numerical field. Thickness of the wall. This field may be filled when inserting the wall. When you click on the field, an arrow appears on the right side of the field which opens a window for editing the thicknesses of the “right” and “left” side of the wall. Thus you can create an asymmetrical wall. In this case the broken line inside the wall is no longer the axis of that wall.

Partition structure type

Selection field. Type of partition structure. When specification of partitions is done in Instal-heat&energy, and partitions have already been defined there, 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 wall 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 / UN / R

Numerical field. Coefficient of heat transfer across partition / thermal resistance of partition. When 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.

Height within axes [m]

Numerical field. Height of wall within its axes. Value taken from storey data of the building structure.

Area within axes [m2]

Numerical field. Wall surface area within its axes. Value in brackets indicates area calculated from data in the drawing.

Length within faces [m]

Numerical field. Length of wall within its faces. Cannot be modified. Value in brackets indicates length read from the drawing.

Height within faces [m]

Numerical field. Height of wall within its faces. Value taken from storey data of the building structure.

Area within faces [m2]

Numerical field. Wall surface area within its faces. Value in brackets indicates area calculated from data in the drawing.

Outer length [m]

Numerical field. Length of wall in external dimensions. Cannot be modified. Value in brackets indicates length read from the drawing.

Outer height [m]

Numerical field. Height of wall in external dimensions. Default value is equal to the height within axes.

Outer area [m2]

Numerical field. Surface area of wall in external dimensions. Value in brackets indicates area calculated from data in the drawing.

Calculated in Instal-heat&energy

Selection field. Determines whether partition is to be accounted for in Instal-heat&energy during heat loss calculations.

Wall type

Selection field. The available entries are “External” and ”Internal”. The type of wall is important when placing heating zones in the rooms. The strip of non-heated floor along the wall is taken into account, and the width of that strip depends on the type of wall. The spacing for external and internal walls is specified in “Options / General data” (F7).

No. of arc segments

Numerical field. Number of segments of polyline used to draw the curved wall. Value in brackets indicates the value determined automatically from the maximum angle of inflection. You may specify other value – then the value is adapted to the number given.

Spacing between HZ and wall

Numerical field. Distance between heating zone and wall. Value in brackets indicates a value entered automatically depending on the type of wall. You may enter a non-standard value of the spacing.
