Edith Green-Wendell Wyatt Federal Building
The US General Services Administration wanted to optimize the 1970’s 18-story Edith Green-Wendell Wyatt Federal Building. Targeting an energy savings of 30% over ASRAE/IESNA Standard 90.1-2007 per the 2009 American Recovery and Reinvestment Act (ARRA) and a 55% reduction in fossil fuel energy over a Commercial Buildings Energy Consumption Survey (CBECS) baseline, the GSA and design team pursued an integrated design approach.
Glumac’s expanded building commissioning and energy modeling service supported the team in achieving these goals. In addition, Glumac performed peer reviews (mechanical design) for the GSA and helped convert the mechanical design implementation method from traditional delivery to design build. At the onset of Glumac’s commissioning effort, Glumac performed a fatal flaw analysis of the core and shell design, identifying risks the owner felt hadn’t been addressed previously. This prompted a comfort analysis which led to a redesign of Edith Green’s mechanical system at the building perimeter.
The Edith Green-Wendell Wyatt Federal Building reused nearly all of the existing structural elements, significantly reducing the embodied carbon compared to a conventional building. In the first full year of operation, the building recorded 39% energy cost reduction and 45% energy use reduction compared to Standard 90.1-2007. In addition to the building performance, the design team credits the integrated design process with cutting reduction in requests for information (RFIs) by more than half (measured against comparable projects by the same architect) and cutting the paper used for architectural contract documents by 92%.

Clad in a new envelope of glass and steel with a sloping rooftop solar parasol, the Edith Green-Wendell Wyatt (EGWW) building bears little resemblance to the white concrete façade of the original 1970s building. Exterior shading and radiant systems provide excellent comfort and energy efficiency. But energy-optimized buildings can’t be handed over “as is” at completion and be expected to thrive. | Read More
