provided. Because it ventured so
much into uncharted territory, the
Outagamie Airport project could be
seen as a true demonstration project.
For its participation in the pilot program, Outagamie Airport received
federal Airport Improvement Program
funding for its planning. In addition, the construction of the facility
received partial federal funding.
As part of the owner’s decision to
pursue a net zero energy facility, the
design team was retained to calculate
the design premium and the return on
investment for the various proposed
systems. It was determined that the
premium was about 20% and that the
ROI for primary systems was seven
years or less. It is difficult to compare
square-foot costs, as this building is of
a modest size ( 8,200 ft2) while many
airport facilities are significantly
larger. Thus, the economies of scale
in terms of contractor pricing were not
realized. However, the awarded general contractor was familiar with most
of the building assemblies and provided favorable pricing. The $375/ft2
costs for the Outagamie Airport’s
new General Aviation Terminal are
in line with larger terminal buildings with the highest level of finish,
which was our programmatic directive for this project.
As part of Outagamie Airport’s
commitment to sustainability,
ambitious energy performance and
sustainability goals were set for the
General Aviation Terminal building.
The energy performance targets for
the building are:
For the pilot project, the airport
proposed to develop a demonstration
project that could be used as a real-
life case study. The airport previ-
ously had developed a strategic goal
of becoming carbon neutral by 2030.
The master plan identified a phased-in strategy to achieve this goal.
Using the planning goals set forth
in the Sustainable Master Plan,
Outagamie Airport moved to build a
general aviation campus to the south
of the commercial air service passenger terminal that serves corporate or private travelers in addition
to aviation enthusiasts.
To date, no other aviation passenger terminal facility had been built
using a net zero energy approach.
Outagamie Airport went against this
trend. It used LEED specifications
to deliver a facility that performs to
a level that facility operators feel
can be tweaked over the next couple
of years to generate more energy on-site than it consumes.
Taking advantage of existing infrastructure, the new campus includes
the general aviation terminal, a corporate hangar and a storage hangar capable of housing multiple corporate jets.
Additional hangars are planned for the
future, including the relocation of an
existing hangar on airport property.
Aviation-approved general contractors, because they usually only work
on airport projects, are largely unfamiliar with high-performance building
practices. Also, funding sources (state
and federal) were unclear on what
the impact of the energy-efficiency
goal on facility operations would
be. Similarly, the return on investment was unknown, and ongoing
operational training for both owners
and tenants alike would have to be
