Many buildings constructed today extend one or several floors below grade level. These below grade areas provide functional spaces for uses such as storage, office space, mechanical/electrical rooms, parking, tunnels, crawlspaces, etc. While below grade areas in buildings provide important critical functions for the building, the subject of below grade building enclosure systems, although widely addressed during construction practices is not always wholly understood. The below grade portion of the building enclosure is seldom analyzed numerically in design. Acceptance of poor performance of the below grade building enclosure is typical and historically not questioned.
