Saint Elizabeth Home East Greenwich, R.I..

In its capacity as a National Grid Project Expeditor, RISE conducted a free assessment of Saint Elizabeth Home’s exterior lighting and mechanical systems to identify recommended energy-efficiency measures, which included upgrading the lighting fixtures and installing variable frequency drives (VFDs) and controls, kitchen ventilation system controls, and vending machine controls. These measures resulted in a projected $35,000 in annual energy savings.
