D132 ENERGY & PROCESS ASSESSMENT PROTOCOL
D.7.9.5 Power Use for Lighting during the Day (Waste)
Figure D216. Lighting in warehouse: without daylighting (left) and with skylights (right).
Electronic lighting is a major energy consumer in warehouses. One of the best
ways to decrease electricity used for electronic lighting is to use natural daylight
whenever possible (Figure D216) and to turn lights on only when needed.
D.7.10 Catering
D.7.10.1 High-Flow Prerinse Spray Nozzles Use Large Volumes of
Water to Rinse Soiled Wares (Waste)
Figure D217. High-fl ow (left) and low-fl ow (right) prerinse nozzles.
High fl ow prerinse spray nozzles (>1.6 gpm) are simplistic in design and use
large volumes of water to rinse soiled wares. Low-fl ow, high-performance nozzles
(<1.6 gpm) are engineered to use signifi cantly less water and still effectively clean
soiled wares (Figure D217). Low-fl ow nozzle design elements can include in-
creased head pressure, optimized spray pattern, and aeration of the water stream.
Annual operating cost savings from replacement vary from $100 to $600.
