The air is supplied through individual tenant- controlled floor diffusers, providing tempered air at a more comfortable temperature. Please note that the local floor diffusers can be arranged in various configurations to meet the tenant’s requirements. Each RTU, with evaporative condensing, has an economizer cycle providing additional energy savings. The RTUs and ACFs are provided with noise attenuation to ensure a better work environment. The RTUs and ACF units provide continuously filtered tempered air. Positive building ventilation is provided by the RTUs to assure a fresh indoor 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 ensures 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 ensure 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.
