Seven Generations LLC of Fort Collins, Colorado asked RB+B Architects, Inc. to design a campus of three high performance core and shell office buildings (two 10,000-square-foot one-story buildings and one 36,000-square-foot two-story building) that could be built on a traditional construction budget. This developer believed that offering high performance office space at the same cost as traditional office space would give them an edge in the market place and would help them spread the word in the community that building in a more sustainable way is not only the right thing to do to combat climate change, but economically viable. In a collaborative effort, the project team produced a designed that was "Design to Earn the Energy Star" and has achieved LEED-CS® Platinum Level Certification. The nationally recognized Energy Star and LEED® programs were utilized to validate the project's high performance claims.

The site is within walking distance of basic services and open space was preserved where possible. A local bike path coupled with bike racks and showers support alternate methods of transportation. Preferred parking for Fuel Efficient Vehicles was provided to encourage reduced fossil fuel use by building occupants. A concrete parking lot was utilized to reduce heat island effect around the campus.

The building utilized raised access floors for under floor air distribution (UFAD), which is more efficient and controllable than traditional overhead air distribution. Extensive daylighting reduced the need for electric light during daylight hours. A high performance building envelope reduced the heating and cooling loads and the size of the mechanical equipment. Low flow plumbing fixtures such as dual flush toilets and 1/8 gallon per flush urinals maximized water efficiency within tenant spaces to reduce the burden on municipal water supply and wastewater systems, and drought tolerant landscaping reduced the use of water on the site. A small demonstration solar array helped offset some of the building's electrical usage.
