Regeneron, Headquarters Expansion

Vanderweil provided MEP engineering services for the expansion of Regeneron’s Tarrytown, NY campus. This encompassed the design of two new LEED Gold buildings and an 800-vehicle parking structure for a total of 300,000 sf of new facilities.

The two new buildings comprise a 110,000 sf drug discovery lab facility and a 140,000 sf administration building. The lab facility features both general research and biosafety lab areas (through BSL-3) for biochemistry and genetics research. The administration building is comprised of open and private offices, conference rooms, and an auditorium.

Vanderweil designed an air-cooled chilled water plant, which serves as a back-up in case the campus plant goes offline. While the existing campus plant must produce 45° F chilled water to building, increasing campus demands would occasionally prevent it from achieving this temperature. The new air-cooled chiller plant added by this project has the capability of trimming the campus chilled water to 45° F.

Campus electrical systems were also upgraded during the HQ expansion. The project added an emergency distribution system providing back-up power to the entire facility and the back-up air-cooled chiller plant. The emergency distribution system includes two 2,000 kW, 480/277 V paralleled diesel generators, a 1,500 kW, 480/277 V diesel generator, and multiple automatic transfer switches supplying life-safety and standby loads.
