7.2 Type of building
The building type is used to take into account the heat storage capacity of the
building's mass and the thermal inertia of the building compared to fluctuations
in the outdoor temperature. The lighter the building and the thinner its insulation,
the faster the controls will respond to changes in outdoor temperature (known
as "adjusted outdoor temperature calculation").
It is the adjusted outdoor temperature value that is used for the warm weather
shutdown (WWSD) and to calculate the supply temperature using the charac-
teristic heating curve (Fig. 7).
For building type three levels are available:
– Building response 1 (low)
Buildings with small heat storage capacity and low to medium levels of
insulation, e.g. 2x4 wood frame or prefabricated construction with typic-
al insulation.
– Building response 2 (medium)
Buildings with medium heat storage capacity and high levels of insulation,
e.g. 2x6 wood frame or cinder block construction with above average
insulation.
– Building response 3 (high)
Massive buildings with high heat storage capacity and high levels of
insulation, e.g. poured concrete, heavy brick or heavy cinder block
construction with excellent insulation.
Note: In areas where rapid changes in outdoor temperature occur, choose
Building Response 1.
