HEATING SYSTEM The building heating load shall be covered by a gas fired low NOx condensing boilers with each boiler capable of operating at 60% of design load. Natural gas is the fuel source for the building. 2. HEATING /COOLING SYSTEM TO OFFICE SPACE A VRF Air Conditioning system throughout the office space consisting of above ceiling VRF terminal units with insulated supply air ductwork to ceiling mounted grilles. The fresh air requirements for occupants shall be provided from roof mounted AHUs through supply air ductwork to the rear of the VRF units. The return air path shall be through the office perimeter to the atrium space and extracted at the roof level of the atrium. 3. AIR CONDITIONING SYSTEM The air handling units shall be provided with a high efficiency, thermal wheel heat recovery device to preheat the incoming ventilation air in the winter. The building in general shall be air conditioned VRF units. Fresh air will be provided through a central air handling unit(s) located on the roof. Supply air shall be distributed via sheet metal ductwork from the AHU and penetrate the space at high-level at a number of locations complete with fire dampers and volume control dampers. The air will be ducted into the ceiling voids adjacent to the local cooling unit. The temperature of the air delivered to each zone will be controlled to deliver adequate cooling or heating to the space. The atrium shall be designed to be naturally ventilated and provided with underfloor heating consisting of Polyethylene pipes cast into the concrete floor topping. The room temperature shall be controlled by wall mounted thermostats and floor temperature sensors, which will control the flow of water to the slab on an on/off basis. 4.
