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 as well as large vivarium for the care and study of research animals. 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.
