Client Portfolio
Heffron’s relationship with Georgetown University spans nearly nine decades — one of the longest continuous client relationships in the firm’s history. The work has touched nearly every building type the university operates, from 1930s observatories to LEED Gold science buildings, with the central chiller plant expanded under live campus operation in between.
Today, Heffron continues to serve the campus as an ongoing mechanical service provider — handling routine maintenance, equipment retrofits, and 24/7 emergency response across the university’s facilities. Heffron is also supporting a campus-wide energy efficiency initiative aimed at improving system performance and reducing operational costs.

Washington, DC • 9,000 tons added · WBC Star Award 2004
Heffron installed three 3,000-ton chillers in Georgetown’s central plant — adding 9,000 tons of cooling capacity to a system that could not afford a minute of downtime. The hospital and academic campus stayed at 100% operation throughout the entire installation.
Delivered on time, under budget, and recognized with the Washington Building Congress Star Award for Complexity and Achievement. The work set the template for how Heffron sequences major plant upgrades inside live, mission-critical campus environments.
Washington, DC·LEED Silver • Completed March 2010
Heffron delivered the full mechanical and plumbing scope for the LEED Silver Hariri Building — central station air handlers, terminal units, chilled water and hot water piping, steam and condensate, and ATC controls.
The plumbing scope included fixtures, domestic booster pumps, and complete domestic water distribution, integrated alongside the architectural finish program for one of Georgetown’s signature academic buildings.
Washington, DC • 154,000 SF · LEED Gold · Completed Aug 2012
Heffron helped deliver Georgetown’s first LEED Gold–certified building: 154,000 SF of teaching labs and research space served by an enthalpy-wheel total energy recovery system and a hydronic chilled-beam comfort cooling system.
The project included rainwater reclamation for irrigation and low-flow plumbing fixtures throughout — a mechanical scope engineered for both research performance and long-term operational efficiency.
