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.
