Our Firm

The Green Engineer, Inc. is a sustainable design consulting firm specializing in energy efficient and sustainable design solutions for the built environment. Founded in 2005 by Chris Schaffner, PE, LEED Fellow, the firm has a technical staff of twenty LEED-Accredited Professionals. The expert team brings to the table experience and perspective from a variety of backgrounds including engineering, architecture, construction, planning, development, and public policy. We practice Integrative Design and see sustainability as a core goal shared by design team members and stakeholders. Our practice uses tools such as energy and daylight modeling and life-cycle assessment of materials to analyze performance and inform our decision-making. We also consult for non-LEED clients, including affordable housing and other non-profit developers. To date, we have managed or been involved in more than 170 LEED certified projects in New England and around the country, including 10 LEED Platinum projects.

We use Building Performance Analysis as both a design and compliance tool, working on a range of projects covering early stage thermal and daylight modeling to a whole building’s energy compliance. We have in-house, registered Professional Engineers, Architects, ASHRAE Certified Building Energy Assessment Professional (BEAPs), Certified Passive House Consultants (CPHC), and Building Energy Modeling Professionals (BEMPs). TGE uses industry standard modeling software to develop building performance models. Our energy modeling team has been selected by utility companies to provide modeling services related to incentives on multiple projects.

A Massachusetts Benefit Corporation and B Corporation


The Green Engineer is legally incorporated as a Massachusetts Benefit Corporation, a unique business model designed for for-profit companies that have social mission beyond profit. As a Benefit Corporation, we file an annual report to the State outlining our public benefit, and conduct a third party review of our operations. This review has resulted in our additional certification as a B Corp. We’re one of less than 2504 Certified B Corps world-wide, and one of only five companies in Massachusetts who are both a Certified B Corp and a Massachusetts Benefit Corporation. As part of our business model, we are an employee owned company. Today, more than 75% of our full-time staff members are also owners.

In 2018, The Green Engineer was recognized in the BCorp Best For The World Overall list, which includes businesses that earned scores in the top 10 percent of more than 2,400 Certified B Corporations across all categories on the B Impact Assessment. The Green Engineer is also an honoree in the Best for The World Environment and Best for the World Workers categories as well.
