This article describes how the Free Floor Space rule works and how you can configure the rule.
The building envelope refers to the physical barrier between the interior and exterior environments of a building. It includes all the elements that separate the indoor conditioned space from the outdoor environment, such as walls, roofs, windows, doors, and foundation.

With this rule, you can verify that the external walls match the walls surrounding gross area spaces and/or all spaces within the model. Ensuring that external walls match the spaces they enclose is essential for maintaining thermal performance, moisture control, structural integrity, regulatory compliance, and aesthetic quality in building construction.
The rule checks that the space or space group being checked is surrounded by external walls, which make up the building envelope. A wall is considered an external wall by the rule, if the value isExternal = True in Pset_WallCommon:
You can set external walls to be any set of walls. To edit external walls manually, you can open the Compartmentation view:
In the Parameters view, you can select if the rule checks for building envelope elements around spaces and/or space groups. You can then define the space(s) and/or space group(s) to be checked more specifically.
