LABORATORY SUMMARY (CONTINUED...)

BUILDING SYSTEMS: HVAC SYSTEMS EVALUATION

The mechanical equipment serving the first floor includes water cooled chillers, gas fired furnaces in the air handlers for preheat, gas fired boilers for steam humidification, air handlers and terminal control boxes with electric reheat. The system meets current codes. The equipment has sufficient capacity to accommodate typical R&D lab tenants, GMP lab tenants and light manufacturing lab tenants. Heating System Heating is furnished via a combination of rooftop pre-heat and terminal reheat. The air handlers include natural gas fired furnaces for air preheat. The furnaces are 1500 MBH input capacity each (one per air handler). Terminal reheat includes electric reheat coils integral with CAV and VAV boxes for zones. The equipment is in good condition. Cooling System The facility is cooled by two water cooled centrifugal chillers with 200 ton capacity each. The air handling units include chilled water cooling coils. The chillers are served by one 400 ton outdoor cooling tower. The cooling plant has partial redundancy as the connected cooling load is 288 tons. There are multiple base mounted pumps serving both the chilled and condenser water loops. Ventilation The air handling equipment supplies the building areas with ±68% outdoor air for unit 1N – lab air is all single pass as transferred from the office areas. The east air handling unit is a 100% outside air unit as it serves only lab and lab support areas.
