ceiling mounted slot diffusers at the perimeter spaces and to ceiling mounted diffusers at the interior spaces. Diffusers for the interior spaces can be arranged in various configurations to meet the tenant’s requirements. Each VAV RTU has an economizer cycle providing additional energy savings. The RTUs and fan powered VAV terminal units provide continuously filtered tempered air. Positive building ventilation is provided by the RTUs to assure a fresh inside environment. The ventilation system is designed so that portions of the building may be operated independently. Building heating is accomplished by perimeter fan powered VAV terminal units with hot water heating coils supplied from the building hydronic heating system. The temperature of each unit is controlled by perimeter thermostats. The hot water used within the hydronic heating system is generated by high-efficiency gas-fired condensing boilers, each of which has additional capacity for reliability and economic control operation. This assures an even “blanket” of heat at the exterior wall and glass.

The overall heating, ventilation and air conditioning system serving the building is monitored and controlled by a direct digital computer based control system. The control system automatically coordinates the function of all mechanical components to assure economical and reliable operation. The system may be monitored within the building and remotely for failures of equipment or operating criteria outside of pre-set levels. The HVAC system is designed to maintain a 72º Fahrenheit temperature (+/- 2º) with summertime relative humidity levels at 50% with a 5% +/- variance. The building has a night set back mode whereby interior temperatures will seasonally vary outside the target temperature.
