Defining spaces for the calculation of thermal loads

Non-habitable spaces

The definition of non-habitable spaces involves setting the following parameters:

Space classification: Non-habitable

Loss reduction factor 'b'
Define the loss reduction factor ‘b’, which regulates heat transfer from habitable spaces to the outside via non-habitable spaces.
- Calculated
- Custom
  - Force the loss reduction factor 'b'

Airtightness level (if the "Loss reduction factor 'b'" is "Calculated")
The airtightness level is defined based on the number of air changes per hour in the room:
- Completely airtight (0.1/h)
- No ventilation openings (0.5/h)
- Small ventilation openings (1/h)
- Permanent ventilation openings (3/h)
- Large or multiple ventilation openings (10/h)
- Custom
  - Outdoor air exchange rate (^h⁻¹)
