Defining the characteristics of the spaces in the project library is necessary to classify them as habitable or non-habitable and to specify the parameters for ventilation, lighting, occupancy, and internal fittings that affect the program's analyses.

The tools for managing the model’s room libraries can be found on the "Building" tab and, within the "Project" tree view, in the "Libraries" section, after selecting the "Spaces" level.

Entries can be exported to files on the hard drive with the .bib933 extension.

The parameters used to define each room in the library depend on the type of project chosen:

• Defining spaces for building energy simulation
• Defining spaces for the calculation of thermal loads
