GSA is dedicated to improving building performance and reducing energy use and environmental and health impacts of federal buildings. The U.S. Congress mandated in the Energy Security and Independence Act of 2007 (Section 491) that the Office of Federal High-Performance Buildings (OFHPB) conduct demonstration research projects at selected federal green buildings in order to improve understanding of how sustainable technologies and approaches can improve building performance. In 2013, GSA finished a multi-year demonstration research project on the EPA Region 8 Headquarters building, also known as The Wynkoop Building.
The Wynkoop Building in downtown Denver, which houses the EPA Regional office, is “build-to-suit” LEED Gold office/retail space designed and constructed through a design-build public-private partnership to be as sustainable as technology and budget could support, incorporating sustainability elements developed jointly by GSA (Government lessor) and EPA (tenant agency).
The research deployed scientific teams from two national Department of Energy (DOE) laboratories as well as academic and public sector organizations to assess performance in acoustics, underfloor air distribution, data center energy use, daylighting, indoor water use, thermal comfort, occupant experience, workplace functionality, and green roof applications for the Denver climate. In all cases where the building was underperforming, the research teams made recommendations for improvements. Some of those improvements were made, while others required future funding. The final report documents key findings and lessons learned regarding the facility’s design, construction, and actual sustainability performance.
This research provides unique insights into how a complex building works. Most buildings go through a fine tuning experience that may take many years. Yet, we know little about how occupants and buildings “learn” to adjust over time and what kinds of changes are made. Building performance results are seldom made public. Furthermore, fine tuning is often ad hoc rather than subject to rigorous research necessary to identify causes and propose solutions as was done in the Wynkoop Building research. Solutions were tested in the building where time and funding permitted.

Traveler reimbursement is based on the location of the work activities and not the accommodations, unless lodging is not available at the work activity, then the agency may authorize the rate where lodging is obtained.
Unless otherwise specified, the per diem locality is defined as "all locations within, or entirely surrounded by, the corporate limits of the key city, including independent entities located within those boundaries."
Per diem localities with county definitions shall include"all locations within, or entirely surrounded by, the corporate limits of the key city as well as the boundaries of the listed counties, including independent entities located within the boundaries of the key city and the listed counties (unless otherwise listed separately)."
When a military installation or Government - related facility(whether or not specifically named) is located partially within more than one city or county boundary, the applicable per diem rate for the entire installation or facility is the higher of the rates which apply to the cities and / or counties, even though part(s) of such activities may be located outside the defined per diem locality.
