Centerbrook's office was originally a nineteenth-century mill building. Since the 1970s Centerbrook has adapted the building to meet the needs of a twenty-first century architect's office. The firm uses the building as a laboratory for green architecture. This allows Centerbrook to demonstrate the viability of sustainable technologies to its clients and the public.

Centerbrook uses clean energy to generate approximately 30% of its annual electrical needs.

Centerbrook's property, sited on the Falls River, has been a water-powered industrial site since about 1697. In 1982 Centerbrook installed a new hydro power turbine which generates 11% of the firm’s electricity.

Centerbrook uses solar energy to generate another 19% of its annual electrical needs. In 2006 Centerbrook installed solar photovoltaic (PV) panels on two rooftops of its office. The 16.5 and 26.4 Kilowatt systems were installed with the support of the Connecticut Clean Energy Fund and Federal Tax Credits available in the 2006 National Energy Plan.

U. S. Senator Joe Lieberman dedicated Centerbrook’s 16.5 Kilowatt solar energy system on February 21, 2006. Senator Lieberman said he was at Centerbrook Architects "...to celebrate them and thank them for being good citizens, good corporate citizens, for not only being concerned about our dependence on fossil fuel but for doing something about it."

In 2005 Centerbrook installed a green roof over a portion of its office. It helps control heating and cooling costs and reduces air pollution and storm water runoff. The roof also serves Centerbrook staff as an on-site experiment into the suitability of a variety of plants for use as roofing material.
