Genzyme Center

Biotech company Genzyme went green when it built its corporate headquarters in Cambridge, Mass. Called Genzyme Center, the 4-year-old structure is a Platinum-level LEED-certified green building, the highest level possible. (LEED stands for Leadership in Energy and Environmental Design, and LEED certification is granted by the U.S. Green Building Council.)

The builders and architects focused on creating a healthy working environment for employees by bringing in daylight and outside air. The Genzyme building, also featured in this News.com video, uses several high-tech features, including a building management system that controls a network of sensors and heliostats on the roof that collect light and reflect it into the building.

The building is in Kendall Square, located on a contaminated site where there once was a factory and a storage site for coal burned in a power plant next door.
