D.7.9.3 Signifi cant Infi ltration through Truck Docks (Waste)
Figure D214. Example dock seals used in warehouses.
Loading docks are typically the areas with high air infi ltration that results in
energy waste and discomfort for workers in adjacent areas. The dock seal
(Figure D214) signifi cantly reduces air infi ltration at the loading dock by pro-
viding a seal between the truck and the building. Performance of the seal will
vary depending on the fi t between the truck box and the dock seal. The driver’s
skill at docking the truck and the design of the truck box are both factors in
determining the savings.
D.7.9.4 Lighting Levels Greater Than 161.4 lux (15 Footcandles)
(Waste)
Figure D215. Storage building with good
lighting system.
A storage operation is an area where spare parts are located. The major activ-
ity is fi nding the correct location for a part and either retrieving it or placing a
new one there. Lighting is required for reading labels and safely navigating the
storage area. The appropriate lighting level for movement and identifying parts
is 161.4 lux (15 footcandles) (Figure D215). If a lighting level that exceeds this
level is required, task lighting can be provided. Task lighting will provide the
opportunity to reduce the intensity of the area light system, allowing energy to
be saved.
