Sustainability Guide for Existing and Historic Properties


Location: Washington, D.C.


Intent:  Prepared the “Sustainability Guide for Existing and Historic Properties” for the DC Department of Energy and Environment intended to promote and facilitate green retrofits of existing older buildings in a manner that will improve their performance and energy-efficiency while also being respectful of their historic character and features. Specifically, the Guide covers various topics such as identifying inherently sustainable building features commonly found on historic buildings, initial steps to take when planning a sustainable retrofit or efficiency upgrade, retrofit strategies for building components, technical guidance and available funding sources, and a general overview of DC’s historic preservation regulations. The project involved an extensive review of existing sustainability studies, best practices, and guidelines implemented by other municipalities. The guide was prepared with regular review and input from District agencies including the Department of Energy & Environment, the Department of Consumer and Regulatory Affairs, and the Office of Planning, Historic Preservation Office. The guide was adopted by the DC Historic Preservation Review Board in early 2019.
