A primary technical justification for door replacement is reducing air leakage. Older doors, particularly those with single-panel designs or degraded weatherstripping, contribute to the "stack effect" where conditioned air escapes through gaps.

The environmental calculus of door replacement is paradoxical. While new doors improve energy efficiency (reducing operational carbon), the disposal of old doors contributes significantly to construction and demolition (C&D) waste. The EPA estimates that 1.5 million tons of doors enter U.S. landfills annually, of which only 12% are recycled or salvaged. door replacement
The building envelope is the primary interface between a conditioned interior and the external environment. Within this envelope, doors represent a significant thermal bridge and security vulnerability (DOE, 2020). Unlike window replacement, which has been extensively studied, door replacement receives less academic attention despite comparable impacts on air infiltration. This paper examines the four primary drivers of door replacement: energy loss, physical deterioration, security upgrades, and aesthetic renovation. A primary technical justification for door replacement is
