Setting the building time constant
The building time constant specifies the ability of the building to retain heat. The building constant is
dependent upon the type of building (see table). The value (select with the rotary knob and confirm with
"OK") is also dependent on individual temperature perception, and so the information in the table should only
be treated as a guide. Recommended are:
Building
type
Heat retention ability
Recom-
mended value
Light Low heat retention ability, e.g. prefab / wood-frame houses approx. 10h
Medium Moderate heat retention ability, e.g. house made from hollow blocks approx. 20h
Heavy High heat retention ability, e.g. brick house approx. 30h
Very heavy Very high heat retention ability, e.g. exterior and interior walls > 30cm approx. 60h
Passive Well-insulated, e.g. zero-energy housing approx. 100h

Setting the standard heating load
Set the standard heating load (select with the
rotary knob and confirm with "OK"). The standard
heating load is obtained by multiplying the specific
heating load by the living area to be heated. You
can calculate the standard heating load from the
following table.
Building performance requirements
Year of construction Specific heating load
Up to 1970, uninsulated 120 - 180 W/m 2
1977 to 1984 70 - 100 W/m 2
1985 to 1995 50 - 70 W/m 2
Building performance requirements
Year of construction Specific heating load
New build, EnEv 40 - 50 W/m 2
New build, KfW 40/60 20 - 30 W/m 2
Zero-energy house 10 - W/m 2
