The Denver Architectural Foundation is excited torecap our past hard hat tour of the Byron G. Rogers Federal Office Building (BGRFOB)!  Located in downtown Denver, the BGRFOB is an 18-story, 494,000 square foot building completed in 1965 that houses several Federal agencies.  The original architect was the joint venture firm of Fisher and Davis & James Sudler Associates.  Denver Architectural Foundation board member, Alan Golin Gass, FAIA, was the first employee hired to work on the Byron Rogers project and was the only architect to work directly with James Sudler, FAIA, and Rodney Davis, AIA, on the design concept.  Alan still has early sketches of the project concepts that Sudler created.

The current $154 million Byron G. Rogers Federal Office Building Modernization project was funded as part of the American Recovery and Reinvestment Act of 2009.

The primary goals of the design-build project are architectural preservation and demonstration of energy efficient retrofit capabilities that includes complete replacement of all building systems and renovation of all interior spaces.

The ambitious project calls for super-insulating the envelope, complete window replacement, complete mechanical and electrical system replacement, 100% LED lighting throughout the building, asbestos and lead paint abatement, along with comprehensive structural upgrades to adjust for antiterrorism/force protection (blast), progressive collapse, and earthquake preparedness requirements.

One key to the winning proposal was a plan to super-insulate the building from the inside without having to remove the exterior precast aggregate panels which largely define the overall exterior aesthetic of the building and contribute to its status as a historically significant example of mid-twentieth century Formalism architectural style.

Aggressive energy efficiency goals will be achieved by a unique mechanical system utilizing an active chilled beam HVAC system, dedicated outside air heat recovery ventilators, magnetic bearing heat pump chillers, and thermal storage tanks.  These systems allow heating and cooling energy to be moved around the building or stored in the thermal tanks many times more efficiently than generating the energy with conventional boilers and chillers.

All together, the systems are expected to lower the building energy consumption by up to 65% over its previous rate or 50% below modern ASHRAE standards.  When complete, the modernized facility will rival the energy performance of modern greenfield projects such as the NREL Research Support Facility.

The systems are expected to save GSA over $250,000 per year in energy costs and receive $250,000 in Xcel rebates while providing superior comfort and a modern workplace for various federal agencies.  Federal agencies scheduled to occupy BGRFOB include the Social Security Administration (SSA), Securities and Exchange Commission (SEC), National Labor Relations Board (NLRB), Department of Justice Executive Office for Immigration Review (EOIR), Department of Homeland Security – Immigration and Customs Enforcement (DHS-ICE), and the new U.S. Patent and Trademark Office (USPTO).  The new USPTO is expected to provide Denver an estimated economic impact of $439 million over the next five years.

The first phase of construction will be complete in early June 2013 with move-in of the first 7 floors of the building starting in June 2013. The remaining floors will be completed and occupied by the fall of 2014.
