Renovation of Byron G. Rogers Federal Building and Courthouse Helps Revitalize Downtown Denver
The U.S. General Services Administration recently re-dedicated the 18-story Byron G. Rogers Federal Building & Courthouse in Denver, following an extensive modernization.
This high-performance sustainable building project continues GSA’s legacy of outstanding public architecture. The facility was originally built in the 1960s and required a deep retrofit to reduce energy use while preserving its historical significance. The renovated facility is expected to attain LEED Gold certification.
The project cost was approximately $160 million, with $147 million funded by the American Recovery and Reinvestment Act. The funds resulted in a modern, highly-efficient workspace for 11 federal agencies and helped revitalize the eastern edge of Denver’s downtown central business district. The improvements are expected to create 55 percent overall energy reduction in the federal building. GSA will reduce its greenhouse gas emissions by more than 2,908 tons of CO2, which is the equivalent of taking 612 cars off the road or providing energy to 266 average-sized homes.
The primary goal of the modernization was to upgrade all of the major building systems, including replacement of mechanical, electrical and plumbing systems in the federal building. The project also replaced 250 windows in the courthouse with double glaze, low E, gas-filled, high-efficiency units.
“We are one of the largest and most diversified public real estate organizations in the world and as such, we have a responsibility to help lead the government’s sustainability transformation,” said GSA Regional Administrator Susan Damour. “High-performing green buildings provide the best value for the taxpayer and the public because they minimize the federal footprint through efficient use of energy, water and resources, and they create healthier productive workspaces.”
Among the sustainable design strategies:
- Federal mandates require water savings of 20 percent in the building and the design-build goal is to achieve approximately a 40 percent reduction in water use.
- Aggressive energy goal of less than 45.1 kBtu/SF/yr which achieves annual energy savings of approximately 55 percent.
- Solar panels were installed on the roof to offset energy use of domestic hot water.
- The building is primarily heated and cooled through the use of an Active Chilled Beam system. This system uses significantly less energy than the standard conventional HVAC system.
- 50 percent of all construction trash and debris produced during the project was diverted from the landfill.
- Daylighting increased approximately 25 percent from the existing condition.
GSA selected design constructor Mortenson Construction, who teamed with HOK and Bennett Wagner & Grody Architects.
