HOK Architects has been selected as part of a design team to renovate the Byron G Rogers Federal Office Building and US Courthouse in Denver, US.
The $130m renovation aims to receive LEED Platinum certification by reducing the energy consumption of the 620,000ft² facility by 80%.
The electrical, lighting, mechanical, fire protection and plumbing systems at the facility will be replaced, energy storage tanks will be installed and improvements will be made to windows.
Solar thermal panels on the roof will provide hot water to the site while regenerative drive technology will offer a 15% reduction in elevator transportation energy.
Construction is expected to begin in October 2010 and be complete by December 2012.
The design team includes Mortensen Construction, Bennett Wagner & Grody Architects, RMH Group and Rocky Mountain Institute.
