This comprehensive project included new HVAC equipment, controls, lighting, building envelope improvements, and a 40kW solar array. Energy Resources replaced (5) 30-ton water cooled air conditioning units on floors 2-6 with (10) high efficiency 15-ton water source heat pumps (WSHP) equipped with dual enthalpy economizers; replaced (3) 7.5-ton RTU’s with high efficiency units; installed (2) high efficiency condensing gas boilers with outdoor air reset controls; and installed variable frequency drives on cooling tower fans and hot water circulating pumps. We also installed an EMS system with integration of the variable frequency drives, boiler pump and baseboard valves, tower pump and fan, all the 15-ton heat pumps, outside air dampers and dual enthalpy controls.

The lighting portion of the project included upgrading existing interior fluorescent lighting with LED troffer and recessed can retrofit kits. The building envelope improvements included clear silicone caulking of 566 commercial windows, consisting of 19,696 linear feet and installation of 250 v-seal window weather strips; removal and replacement of 2,462 linear feet of window sashes with new weather-strip seals at the top, sides, between and underneath sash of the windows. With anticipated annual savings of 193,427 kWh and 6,641 CCF the project had a 13.5-year payback and was cash flow neutral for the customer through a 15 year CPACE loan.
