GHT designed and executed the relocation of the units without impacting ceilings or the intended architectural design. Our team also specified thermostat locations for each terminal unit, provided CO2 sensors in all conference rooms, huddle rooms, the cafe and in the pantry. The CO2 sensors are tied into the building automation system (BAS) and provide demand-controlled ventilation control.
