Guiding Green Building in DC

District of Columbia Department of Real Estate Services
Sustainable Guidelines and Policies

Washington, DC, USA

HOK developed a series of sustainable design guidebooks for DC’s Department of Real Estate Services project.

The guidebooks are helping DRES teams apply the LEED rating system to construction and renovation projects across the city. 

A brief, whole-process narrative of the LEED building rating system outlines the process of setting up a project for successful certification.

An organizational matrix links essential LEED activities to the appropriate timing in the design and construction process. The guide includes detailed regional and DC-specific information, including relevant allowances or codes best suited for streamlining the certification process.

The books provide guidance for site work, demolition, new construction, interior build-outs, minor renovations and operations. They include recommendations for construction documents and specifications and a section outlining other resources available for assisting design and construction teams. 

HOK is also developing policies to guide DRES’ pursuit of LEED certification for projects across its real estate portfolio.
