Net-Zero Energy

Currently operating at Net-Zero energy and targeting LEED Gold, the Ross Maintenance Facility buildings are outfitted with a 300-kw photovoltaic array and ultra-energy efficient building systems. The administrative building features a radiant heated and cooled slab, LED lighting, and displacement ventilation. Chilled water and heating water for the radiant slabs are provided through an air-cooled, heat pump chiller.  A heat recovery ventilator is used to pre-condition outside air and deliver it to the occupied spaces in the administration building through variable air volume terminal units and displacement diffusers. The high-bay maintenance building uses gas fire-fired infrared radiant heaters and HVLS fans for cooling.
