Clay Tilton focuses on improving existing buildings through thoughtful technical analysis and careful consideration of owner and tenant needs. Clay's previous work involved energy consulting: energy auditing, building models and managing energy improvements for multifamily affordable housing with Sustainable Comfort Inc. Another key project included launching the Building Performance Exchange with Built Environment Plus, a centralized resource for improving efficiency and reducing emissions for large existing buildings in Massachusetts. Connecting professionals and owners with retrofit solutions will become vital as our building stock continues to age.
