Buildings.Rooms.FLEXLAB.Data.Constructions.OpaqueConstructions.ExteriorConstructions

Information

This package contains constructions defining exterior walls used in FLEXLAB test cells. The following table lists locations in FLEXLAB test cells where the constructions are used. Locations of walls in UF90XR are described assuming that the windows are facing south. Some of the constructions are combined into single packages because they are, from a thermal point of view, functionally identical.
