6.1 Personnel Doors
This part of the Energy Efficiency Manual saves energy by eliminating air leakage or “infiltration” through entrance doors. Air leakage wastes energy directly through the need to condition the entering air, and also indirectly by creating discomfort in the vicinity of the doors that motivates excessive heating of those areas. These effects vary widely, depending on the ventilation requirements and layout of the affected spaces.
The energy conservation measures presented here include maintenance of doors, installing effective weatherstripping, installing reliable door openers and closers, selecting high-efficiency doors, installing revolving doors and vestibules where appropriate, and other activities.
