BUILDING THERMAL ENVELOPE

The ‘thermal envelope’ of a building is the union of those structures that SEPARATE the CONDITIONED PART (subject to being heated and/or cooled) of the building from the OUTSIDE (including neighboring buildings). The pictorial indicates the roof, walls, windows, doors, ceiling, basement, infiltration {blue arrows} envelope as shown by the GREEN line at the building exterior. __________________________________________________
