Leeway house had several defective rooftop units and had elevated energy costs. We installed 13 new high efficiency American Standard Rooftop heating and cooling units with economizers and dual enthalpy controllers. We also installed BACnet controls within the units and an energy management system allowing the entire system to be controlled from the facilities manager’s computer. The energy management system further cut power consumption by preventing unapproved thermostat adjustments. The high efficiency units were eligible for rebates from the local utilities.
