Owner: United States General Services Administration
Architect: Pei, Cobb, Freed and Partners
Engineer: Ellerbe Becket
Contract Value: $62 Million

The Ronald Reagan Building, located on an 11 acre site off Pennsylvania Ave, is the second largest government building in the United States.  Designed as a multi-use building, the Reagan Building contains government offices, public-private leased space, trade offices, a business center, as well as retail and research space.

To meet the mechanical need of the building, Pierce Associates installed 7,700 tons of electrical refrigeration in an onsite chiller plant.  Associated with the chiller plant were

12 cooling tower cells, 26 heat exchangers and 150 HVAC pumps.  The hot water heating system used 16 steam-to-water heat exchangers to generate the hot water necessary to feed 66 hot water coils for the air handling units, approximately 800 reheat coils in the VAV system and 12,000 linear feet of fin tube for radiation heat.

Air distribution required 125 air handling units with the largest of these being 81,000 CFM.  Pierce Associates fabricated and installed over three (3) million pounds of ductwork serving nearly 2500 VAV boxes.  Pierce also installed a complete fuel oil system, including a 6,000 gallon underground tank, to serve the building's emergency generator system.
