The Byron G. Rogers U.S. Courthouse, a 265,000 sf $45.8 million renovation project in Denver, is the first General Services Administration (GSA) owned LEED for Existing Building certified building and the first GSA LEED Gold rated building. ambient energy facilitated a sustainable design charrette and meetings, managed LEED construction administration, reviewed drawings & specifications for LEED compliance, performed DOE2 energy modeling, calibrated energy model to utility bills, performed initial ENERGY STAR benchmarking, and is performing ongoing quarterly reporting for three years. The Courthouse is saving:
- 32% on interior water usage; 50% on exterior water usage
- 30% on energy costs
- 100% of electric energy usage is Wind Power
- 50% of open space is vegetated with native of adapted vegetation
- 50% of all building materials have recycled content
- 50% of all wood based materials are from sustainability harvested forests
- 50% of occupants utilize the public transportation program provided by the GSA
- 3% walk and 5% carpool to the building site
