A shred of insight as to how the project team for the Aldo Leopold Legacy Center achieved the highest score of any LEED-certified building.
By now, nearly everyone involved with
sustainability has heard of the Aldo Leopold Legacy Center. It’s become
something of an icon since 2007’s Greenbuild. It was the recipient of Forest
Stewardship Council-US’s (FSC-US) Designing & Building with FSC Award for
its use of FSC-certified wood products. As stated by ED+C publisher and FSC
Award selection committee member, Diana Brown, “This year’s winner, the Aldo
Leopold Legacy Center, exceeded the goals of the award criteria by using 78
percent FSC wood, site harvested and locally processed FSC wood,
showed education in the green building industry and growth in the use of
certified wood in the community. An outstanding
project!”
But that was just one of the accolades this project received. Of those other
accomplishments, the one most noted is its achievements with LEED. Not only was
it certified LEED Platinum, it did so with the most LEED points accumulated by
a project — ever — with 61. Based on the scorecard (which you can view at
www.EDCmag.com), if the project team attempted to achieve the point, it
succeeded. But how did this project team succeed when others attempt to do the
same all the time and fail?
“Buddy Huffaker [executive director for The Aldo Leopold Foundation] challenged
the team with the thought of building a carbon-neutral building,” says Joel S.
Krueger, architectural project manager for The Kubala Washatko Architects Inc.,
the project’s architect. “This, of course, is tough as it is hard to determine
one’s realm of influence. What do you include in your calculation of carbon
production, where do you stop? This idea forced us to work very hard to
consider every move; where are materials coming from, how can the building
become a producer of energy rather than a consumer, is it ok for staff to drive
to work? This was an amazing exercise.”
But, says Huffaker, the team just followed The Aldo Leopold Foundation’s
tenets. “From the beginning we were informed and inspired by the work and ideas
of Aldo Leopold. We felt if we upheld our interpretation of his call for a
land ethic, in essence an appreciation, understanding, and respect for nature,
that we would be able demonstrate what a sustainable building could
accomplish.”
The team’s ability to maximize the site-specific
elements for the project sets it apart. It’s one thing to take from an area
without regard for the property’s natural elements. It’s quite another, though,
to use what nature gives you. The Aldo Leopold Legacy Center used what it was
“given” more than it “took” better than any other perhaps any other project
that has applied for LEED certification. Most notably,
lumber.
“This project is unique from a contractor’s perspective in the extensive use of
site-harvested lumber,” says Gregg Tucek, project manager, Central Operations,
for Oscar J. Boldt Construction. “It is used in varying structural elements:
site-built timber trusses, round wood trusses, posts and beams, and round wood
rafters and decking. Additionally, it was used for custom doors, windows,
cabinets and casework, flooring, interior and exterior
siding.
“The same thing that makes this such a unique project also tended to lead to
more ‘out-of-the-box’ thinking regarding education of, and coordinating the
timber harvest, peeling, shipping, kiln-drying, identification of the species
and quantities available for use in specific areas of the building, and then
delivering to cabinet-makers and window manufacturers in a timely fashion to
meet site construction schedules. Needless to say, flexibility was required and
became the key to success.”
As much as flexibility was needed, a measure of rigidity and resolve was needed
to see the owner’s goal fulfilled. Huffaker explains, “There are so many stops
throughout the design and construction process where it would be easier to just
lower the bar and do what is easy, but Aldo Leopold wrote in his seminal book,
A Sand County Almanac, ‘In our attempt to make conservation easy, we have made
it trivial.’ Despite great progress, it isn’t easy to build green. It
takes a lot of hard work by the designers, the contractors, and the
client.
“I think we really raised the bar on what is possible in the built
environment. We had extremely high goals, and in the first year we fell
short on achieving net zero energy, but we were at nearly 85 percent. That
is still terrific. Once we work out some of the bugs and take into account
that last year we set a record for snowfall, doubling the yearly average, I’m
confident we will demonstrate that it is possible for a modern building to
produce as much energy as it takes to operate it over the course of a
year.”
The green community will eagerly wait to see how this record-setting project
fares in the future with its goals. It has become the measuring stick to which
any facility attempting LEED certification will be held. Of course, as we all
know, records were meant to be broken.
Only time will tell what is achieved next.
