D16 ENERGY & PROCESS ASSESSMENT PROTOCOL
D.1.5.2 In Cold and Humid Climates Having Doors or Air-
Conditioned Spaces That Open to the Outside (Applies to Major
Entrances and Exits of a Building) (Waste)
Figure D26. Examples of buildings with air-conditioned spaces open directly to outside; left to
right, open stairways, open terrace, common open balconies (top row), open balconies and an
open internal hallway (bottom row).
Signifi cant air fl ows through open doors result in excessive sensible and latent
loads on air-conditioning systems (Figure D26). In humid climates, this situa-
tion creates a potential for mold and mildew problems.
D.1.5.3 Large Doors in Industrial and Administrative Buildings
Not Protected by Vestibules (Waste).
