He has put that conviction into practice through projects that combine design for environmental stewardship with thoughtful, site sensitive building design. His projects have won local, regional and national awards including multiple Top Ten Green Projects of the Year from the AIA Committee on the Environment (COTE). Henry is past chair of the COTE National Advisory Group and current member of AIA California COTE steering committee, where he advocates for laws and codes that address climate change and the building sector, and for the incorporation of sustainable design values and metrics into architectural awards programs and architecture school curriculums. Henry has taught sustainable design and design studios at the University of California, Berkeley, and is a past member of the University’s Design Review Committee. He has spoken widely on ecological design and the work of the firm and has served on architectural awards juries across the U.S.
