The Center for Environmental Research and Conservation (CERC) is a consortium of five world-renowned scientific institutions: Columbia University, the American Museum of Natural History, the New York Botanical Garden, Wildlife Conservation Society, and Wildlife Trust. Headquartered within the historic McKim Meade & White Schemerhorn building at Columbia University, CERC is also part of Columbia's Earth Institute.The new 18,000 square foot facility incorporates offices, laboratories, a library, and rooftop research greenhouses. The primary mission in the new facility's design was to create a space that fosters interaction between CERC's users while demonstrating environmental responsibility. The primary design organizer was the creation of a three-story central daylight space that becomes its focal point. The design took advantage of the new rooftop greenhouses to create occupiable skylights over the centralized atrium allowing daylight to penetrate deep into the building.
