Managing space libraries
The definition of the spaces in the thermal model libraries is necessary to classify them as occupied or unoccupied, air-conditioned or only heated or cooled, as well as to detail the parameters relating to ventilation and internal heat gains, which affect the analysis of thermal loads by the program.
The tools for managing the space libraries of the thermal model are located in the "Thermal loads" tab under the "Thermal model" tab at the bottom and, in the "Project" definition area, in the "Libraries" tree located by default on the left-hand side.
Unoccupied spaces
The definition of the unoccupied spaces is based on the configuration of the following parameters:
- Space classification: Occupied
- Losses reduction factor 'b'
Defines the loss reduction factor ‘b’, which regulates the transmission of heat from occupied spaces to the outside through unoccupied spaces.- Calculated
- Custom
- Force the losses reduction factor 'b'
- Air tightness (if the "Losses reduction factor 'b'" is "Calculated")
The level of airtightness is defined according to the number of renovations/hour of the space:- Completely airtight (0.1/h)
- Without ventilation openings (0.5/h)
- Small ventilation openings (1/h)
- Permanent ventilation openings (3/h)
- Large or numerous ventilation openings (10/h)
- Custom
- Air change rate (h-1)
Occupied spaces
The definition of the occupied spaces is based on the configuration of the following parameters:
- Space classification: Occupied
- Calculation conditions (Heated and cooled / Only cooled / Only heated)
- Cooling
