Details on Locality
Information about the Building section in the Heat load SP tab of the project level.
You are here:
Select location
Select location: Opens the Locations dialog, where you can choose the location of your project.
Outside air temperature: The Outside temperature of the selected location. The value can be overwritten.
Correction: Value to be entered manually to correct the outside temperature.
Type of terrain
Drop-down list to select the type of terrain. The terrain type determines the wind shield category and is used in the infiltration calculation. Available types:
-
A: rural and coastal regions: The building is largely free exposed to the wind. Open sea, lake and reservoir coasts, deserts, steppes, forest steppes, tundra.
-
B: urban areas: Urban areas, forest and other areas with obstacles. In the surrounding area there are between 10 and 25 m high buildings, trees or similar.
-
C: densely populated urban regions: Urban areas with buildings from 25 m height.
Humidity
The combination of regional humidity and room humidity is used to determine if the dry or wet thermal conductivity of a building material is used to determine U-values.
| Room humidity | Regional humidity | ||
| dry | normal | humid | |
| dry | Λ dry | Λ dry | Λ humid |
| normal | Λ dry | Λ humid | Λ humid |
| humid | Λ humid | Λ humid | Λ humid |
For each building material you can store two λ-values for the cases humid and dry in the master tables. To use this function, deactivate the Use predefined values option in the master tables for walls, ceilings, floors and roofs.
When you import a building from Revit, each component will bring only one λ-value with it. In order to correctly differentiate between humid and dry in the calculation, a manual adjustment of the building materials in the master tables is required.
Consider inner heat loss only from 3°C temperature difference
Enabled: For interior components whose temperature difference is less than 3°C, transmission heat losses are not taken into account and are set to zero.
