JCS Construction Group, Inc. has broken ground on 409 Greenwich Avenue, a three-story, 12,000 s/f mixed-use building on the corner of Greenwich Avenue.

In a space on Tempel Green about two-thirds the size of a football field, Connecticut College is creating a subterranean showpiece for its environmental sustainability programs.

Going green helped the library receive a $1 million grant from the Connecticut State Library, which required the project to meet Leadership in Energy and Environmental Design certification standards, a national standard for sustainable energy created by the U.S. Green Building Council.

The energy in the ground underneath the Green is going to heat – and cool – the new Science Center at New London Hall. It’s one of several energy-saving technologies being incorporated into the building.

State Sen. John W. Fonfara and others celebrated the installation of a new closed-loop geothermal heating system at the Connecticut Landmarks’ Hartford Campus that includes a geothermal system that will replace the existing, inefficient heating and cooling systems and will save Connecticut Landmarks an estimated $3,833 per year in energy costs at the Butler-McCook House & Main Street History Center.
