10.1 Submenu Minimum outdoor temperature
The minimum outside temperature is the average value of the coldest
outside temperatures over the past few years. The minimum outside
temperature, together with the design temperature, defines the end
point of the heating curve. A lower minimum outside temperature means
a flatter heating curve, a higher temperature means a steeper curve.

temperature and minimum outside temperature

minimum outside temperature –20 °C
Examples of the minimum outside temperature of important European
cities (average values) are listed in tab. 23.
If your city is not listed in the table:
Calculate the average of the two cities closest to your city or set the
heat requirement calculation value of the building in the menu.

10.2 Building type, insulation standard submenu
The Building and Insulation standard parameters describe the extent
to which the storage capacity of various materials and insulation
thickness affect the calculation of the adjusted outside temperature, and
therefore the heating curve and switching times.
10.2.1 Building
The specifications for the Building refer to the thermal storage capacity
of the wall construction material. This means that walls with a high
thermal storage capacity (Heavy) respond slowly to changes in outside
temperature. Walls made of bricks, for example, take longer to reach the
outside temperature. This means they store up heat which keeps the
house warmer for longer at low outside temperatures.
With a low thermal storage capacity (Light), the room to be heated quickly
responds to changes in outside temperature. A house made of wood frame
walls, for example, has no storage mass, which means that only the
insulation in the walls influences the specific heat energy demand of the
building.
10.2.2 Insulation standard
The specifications for the Insulation standard refer to the insulation
capacity (heat transfer) of the wall construction material. This means that
walls with thick thermal insulation (Good) respond slowly to changes in
outside temperature. For example, it takes longer for walls with thick
thermal insulation to reach their storage capacity limit, and therefore for
this to be noticeable. For the same reason, brick walls with thick thermal
insulation stay cool or longer. This means they store up heat which keeps
the house warmer for longer at low outside temperatures.
Underfloor heating system
In buildings with underfloor heating systems, the Insulation standard
should be set to Good. The underfloor heating system (heat-up time of
the floor construction) has a similar inertia to thick thermal insulation in
a house.
