Project “Warehouse” is a sizable distribution warehouse that was lit with a mixture of High Pressure Sodium and Metal Halide Sources. The designer specified Accendo HBT8 series luminaires lamped with 6 high lumen T8 lamps due to the ambient temperature of the space. Low occupancy (see Aisle pictures) areas were fitted with individual occupancy sensors and Program Start ballasts to maximize lamp life.
The overall project touched over 5300 fixtures and resulted in a 50% reduction in kW, and a 54% reduction in kWh. When considering the substantial energy savings, HVAC savings, maintenance savings and EPAct tax incentives the project simple payback occurred in six months. The employees on the floor assumed the light levels “nearly doubled” given the increase in the quality and color rendering of the new system.
