Commercial Sustainability Services

The engineers, designers and project managers on the Southface Commercial Sustainability Services team work with clients to achieve their project goals and build capacity and know-how for project teams to carry forward. The quality work we do is possible not in spite of the mission-driven focus that defines us as a nonprofit, but rather because of it. Southface applies its technical acumen through the lens of mission-driven work in an effort to transform the design, engineering and construction industries and provide high quality technical service.



A building audit or assessment is an effective way to evaluate the source or sources of performance problems within a building, and determine the solutions that best address them. Southface has conducted thousands of assessments on single-family, multifamily, and commercial buildings.
