CDC Buildings 20, 34 and 43

A multiphase/multicomponent complex comprising a 75,000 square foot office building (Building 20); a 17,000 square foot transshipping building (Building 34); a 13,500 square foot substation building (Building 43); a 9,800 square foot addition to Building 10; and upgrades to the campus chilled water distribution, fuel oil distribution, and electrical distribution systems. Building 20 includes an integrated facility management control center, security control room, lifestyle fitness center, and offices for facility engineering, facility planning, and project management. Building 34 includes recycling and storage areas, and loading docks. The Building 10 addition houses three 2,250 kW generator sets and four 2,000 kW generator sets to provide the campus with a reliable source of standby power. The chilled water upgrades include conversion to a campus-wide distributed secondary pumping system, chiller and boiler capacity upgrades, and plans for a future three million gallon chilled water storage tank. The campus electrical distribution includes redundant 5 kV building feeders throughout the campus and integrates power transfer and control of engine-generators at multiple locations to provide 2N redundancy across a 15 megawatt system. Sustainable features incorporated into the building include bicycle storage, shower facilities, stormwater fixtures, energy recovery exhaust systems, variable volume air distribution systems, and indoor air quality monitoring.

Central Plant
Chilled water and steam system upgrades include conversion to a campus-wide distributed secondary pumping system, interconnection of two central chiller plants (total 26,000 tons), and plans for a future three million gallon thermal energy storage tank using stratified chilled water. Steam upgrades include a condensate transfer system allowing shutdown of one of two boiler plants during periods of light loads. The standby power system integrates power transfer and control of engine-generators at multiple locations to provide N+1 redundancy across the 15 megawatt system. tems, and indoor air quality monitoring.
