Greater Washington’s Most Trusted MEP Consultants

GHT is a leader in creating sustainable engineering solutions for new and renovated buildings. We provide mechanical, electrical, and plumbing (MEP) engineering design, commissioning, and building energy services for the public and private sectors. Founded in 1965, we are one of the largest locally owned and headquartered MEP consultants in the Washington, DC metro area.

GHT’s history includes serving as MEP consultants on celebrated buildings in Washington, DC – from storied classics such as the White House, Old Executive Office Building, and the Pentagon to new icons like 800 17th Street NW, the US Census Bureau Headquarters, and Constitution Square. GHT has become a market leader through our continued focus on innovative design and reputation as a trusted advisor to the development community. We have proven our ability to bring our clients’ visions to life during both prosperous and challenging economic cycles over the last 45+ years.

A Drive to Innovate

GHT is different from other MEP consultants because of our drive to innovate. We consistently discover new solutions in architectural engineering by applying creative thinking to proven design strategies, with a focus on practical results. GHT’s informed approach will help you develop, design, build, and operate successful buildings.

Some of our most recent success stories include designing a system that creates electricity via natural gas-powered fuel cells and generators; identifying millions of dollars in operational savings opportunities for our clients; and supporting the first project to be certified under LEED v3 in achieving Platinum certification.
