Demonstrating LED and Fiber Optic Lighting in Commissary Applications - (PPT)

摘要

Refrigerant system savings not detected: 1. Heat load obviously reduced 2. Refrigerant system controls need to be recommissioned. Maintenance savings not realized: 1 Maintenance contract could be renegotiated when renewed. LED lights provided reasonable payback: 1. Seeking ESCO/ESPC/UESC involvement to expand to other commissaries. Fiber optic lights are marginal, needs further Consideration: Fort Meade display cases were an unusual height, which impacted illumination levels at top and bottom; Energy is reduced, but so is illumination on product; New light color did not match DeCA standard (3500K); Maintenance labor is reduced, material cost increased; Need to consider visual impact (look) and the space for promotional material.
