Christopher Neilson, AIA, uses design as an act of environmentalism, leveraging sustainable and low-carbon approaches so that both new buildings and historic structures can help address climate change. Driven by a ceaseless curiosity for building systems and enclosures, he envisions innovative solutions that strike a balance between high-performance design and embodied carbon reductions. Neilson is a thought leader in sustainability in Boston and beyond, and he has commanded regional and national audiences, counseled municipalities, and shared his broad experience in the classroom.
