Sustainable New England Architecture

Banwell Architects takes a dynamic approach to sustainability or green design. We recognize the need for responsible, energy efficient designs that optimize the use of natural resources and make use of renewable energy sources where appropriate but also respond to our client’s needs: both functional and financial.


We have found the single most effective strategy is to focus on the building envelope, its roof, walls and floor enclosure; maintaining a continuous air barrier, high-performance insulation integrated with structural elements and weather resistant claddings, with attention to detail and verified with field testing.

We research best choices in building and finish materials; certified programs for wood products, optimal recycled and recyclable content, and regional sourcing.

With an effective building envelope, energy use is minimized and occupant comfort maximized. From this baseline, choices and options for alternative energy, biomass, thermal solar and photovoltaic are considered for their cost and benefit.


Banwell Architects is proud to be one of the area’s leaders in sustainable design since the 1970’s. Our office strives to complete projects that are environmentally conscious in every way, shape and form. We boast the honor of both the 1st LEED Gold Certified Project in New England, as well as the first CHPS School in New Hampshire. Here is a list of LEED and CHPS accredited projects:
