Project Overview
Heffron delivered energy conservation measures across the central heating and cooling plants serving the E. Barrett Prettyman U.S. Courthouse and the adjoining William B. Bryant Annex — a fully occupied federal judicial complex where courtrooms, chambers, and secure spaces cannot lose conditioned air.
The scope centered on replacing end-of-life boilers and upgrading chiller capacity, along with the pumps, piping, valves, and controls that tie the plants together. Each measure was selected for measurable reductions in energy and water use while restoring redundancy and extending the service life of the plant equipment.
All work was phased around the court calendar. Temporary heating and cooling strategies, off-hours tie-ins, and staged cutovers kept both buildings continuously conditioned, and every system was carried through startup, testing, and commissioning to verified performance before the old equipment was retired.
