The historic Byron White Courthouse is home to the 10th Circuit Appellate Court. The 274,000 square foot building houses court rooms, associated judge’s chambers, resource rooms, conference rooms, and office facilities.
Construction began on the building in 1910 and was completed in January of 1916. In 1973 the U.S. Post Office and Courthouse was listed into the National Register of Historic Places. It is a Denver Landmark. In 1994 it was renamed in the honor of U.S. Supreme Court Justice, Byron R. White (1917-2002) who was a native of Fort Collins, Colorado. The building went through a major renovation in 1994.
The mechanical system for the building is a central chiller plant with steam heating from the local utility. Three large chillers, (1)-250 ton chiller and (2)-300 ton chillers serve the building cooling load. The heat produced by the chillers is discharged through the use of (5)-cooling towers located in an area well on the north side of the building. The cooling towers are open cell towers with the condenser water loop being an open system.
The steam system provided by the local utility is routed to (4)-steam convertors located in the central plant. The convertors provide heating for the primary heating water system and the condensate serves as a preheat system for the domestic hot water. Additional tube and shell heat exchangers use the steam to heat the domestic hot water to a distribution temperature of 120 degrees Fahrenheit.
The occupied spaces are served by air handlers located throughout the basement and attic spaces. Each air handler has the chilled water and heating water coils for conditioning of the air. Each window is conditioned by induction units located directly below the window.
We reviewed the building mechanical, plumbing, electrical, and lighting systems, as well as the building envelope to uncover inefficiencies in the systems and identify areas that can be modified for increased energy efficiency. Our review process included visual inspections of the equipment, computer simulated energy modeling, interviews of key building staff, review of energy management trend data, electrical metering of step-down transformers and light-level measurements. Through this process, we discovered several areas where energy conservation measures (ECM) can be applied to reduce overall energy consumption.
