Building Oregon 2007: Cover story

Innovations and acceptance stretch the boundaries of sustainable building.

By Jon Bell

Portland designer Kevin Cavenaugh had sustainability in mind when he drilled below his newest spec office building to tap into a water source for the geothermal heat pump that will heat and cool the four-story structure.

What he found down below, however, was an aquifer potable enough to provide water not only for climate control but for all the building’s water needs, from drinking and flushing to watering a rooftop garden of salad greens for chef Leather Storr’s new restaurant on the top floor.

“Every day he’ll be up there harvesting bib lettuce and arugula for his restaurant,” says Cavenaugh. “That’s pretty innovative.”

While not all commercial buildings shooting for sustainability have their own water source and fresh produce, unique features such as those found in Cavenaugh’s Burnside Rocket building highlight some of the more innovative ways that builders are pushing the green envelope.

“We’ve passed the tipping point in sustainable design,” says Kip Richardson, marketing director for Ankrom Moison Associated Architects in Portland. “It’s no longer about how you’re going to do it, but how far you’re going to push it.”

Richardson says almost all of Ankrom Moison’s projects these days have some sustainable design elements in them. At least two clients, developer Steve Ribeiro in Independence and Vulcan Inc. in Seattle, have charged Ankrom designers with taking sustainability to shades of green beyond Leadership in Energy and Environmental Design (LEED) certifications and other industry measures.

“They’ve said, ‘We want you to explore how far we can go,’” Richardson says.

LIKE CAVENAUGH’S “EDIBLE ROOF,” innovation in sustainability is often about finding new and sometimes site-specific ways to add some shades of green to a building.

Take, for example, the new Siskiyou Community Health Center designed by Ashland architect Ray Kistler. The clinic was built on a unique seven-acre virgin forest site full of fir and oak trees, madrones and ponderosa pines — “Kind of like an arboretum,” Kistler says.

With preservation of the arboreal site in mind, very few trees were cut to clear an area for the clinic, and those that were became part of the building. Kistler says the building’s Zincalume metal roof is not only made from a significant amount of post-consumer product, but it also helps divert rainwater so it can be used for irrigation.

The building also incorporates low-energy lighting and mechanical fixtures, nontoxic paint and natural cork-based flooring.

“The clients were interested in as many green choices as were available,” Kistler says.

Another example can be found at 200 Market Place, a large LEED gold office building in downtown Portland that sports its own 30-kilowatt, natural gas-fired microturbine. The generator produces enough energy to run the 19-story building’s nighttime and emergency lights while emitting 90% fewer pollutants than average natural gas power plants. In addition, the exhaust from the turbine is used to heat the boilers and run the air conditioning unit.

Simply retrofitting 200 Market Place’s water fixtures cut the building’s water use by more than 30% as well.

At Stoller Vineyards Winery, a 370-acre vineyard and winery in Dayton, solar panels atop the business’s new LEED gold winery produce 43,300 kilowatts a year, which has led to a 75% energy savings.

Pushing the green-building ethic farther these days can also go beyond technical or material innovation.

James Meyer, a principal at Opsis Arch-itecture in Northwest Portland, says that not only does his firm occupy a highly sustainable building, but its green streak has proven attractive to other businesses with similar worldviews.

Meyer says the sustainable features of Opsis’ Lovejoy Building, which include radiant heating and automated nighttime air flushing, were partly what drew Nau to the retail space below Opsis. The outdoor clothing company has been ballyhooed as much for its recycled materials and lower-impact, Web-centered approach to retail as its apparel design.

Matching up a firm like Opsis and a company such as Nau in a building like the Lovejoy underscores a core commitment to sustainability, Meyer says.

“What I think we’re seeing,” he says, “is a shift where people have to really start walking the walk and reconciling what they say with what they’re doing.”

WHILE SOME GREEN APPROACHES are pushing the bounds, Ralph DiNola, a principal with the Portland sustainability consulting firm Green Building Services, says the movement as a whole is enjoying popular acceptance.

In addition to the more innovative features — such as an under-the-floor air distribution system in the Royal Caribbean Direct West call center in Eugene — offices and businesses are also taking less-flashy steps to reduce their environmental impact. Those include everything from green housekeeping to commuter incentives and controlled lighting.

“This is all becoming much more mainstream,” DiNola says. “It’s not seen as out-of the-ordinary or risky anymore.”

In fact, some say that sustainable building has become so commonplace that all but the most innovative features are considered standard fare.

“I have a LEED platinum spec office building and I don’t care,” says Cavenaugh. “But there’s good in that. I think that bodes well for the city [of Portland] and for the whole green movement that it’s just kind of gotten to be ho-hum.”

A range of incentives, from the Oregon Department of Energy’s Business Energy Tax Credit to cash incentives from Energy Trust of Oregon, are helping to further mainstream sustainable building. DiNola says sustainable features are also being factored into projects much earlier than they used to be, which helps cut additional design and consulting fees down the road.

Big-picture initiatives are also under way to push sustainable building and innovations. Tom Pene, president of the Oregon chapter of the American Institute of Architects, says the organization is behind a bill in the Legislature that would require LEED gold certification for all public projects in the state. Cities such as Portland already require certification for public projects; the same standards may soon also be applied to major state public projects.

There’s also the 2030 Challenge, issued by the nonprofit Architecture 2030 and adopted by the AIA, which aims to gradually reduce fossil fuel consumption for all new buildings. The goal is to build carbon-neutral buildings by 2030.

While that may seem like a lofty goal, DiNola says that when you’ve got a building like the Stoller winery already cutting energy use by more than 70%, it’s not out of reach.

“That’s already pretty far along that path,” he says.
