While much of the U.S. real estate market has been floundering, one area has not seen a dip. Green building now accounts for nearly one-third of new construction in the U.S. That's up from 2 percent in 2005, according to McGraw-Hill Construction, which tracks the industry.
The numbers suggest a revolution is taking place within an industry that is historically slow to change. There are many factors -- and many players -- in this move toward green building.
But one company and its rating system has been undeniably influential in changing construction practice and policy around the country, despite some people's reservations about whether it's really helping the environment.
University Of Michigan Banks On LEED
The new Ross School of business building at the University of Michigan is full of environmentally friendly technology.
Andy Hoffman, a professor of sustainable enterprise, who teaches a course in green construction, and facilities manager John Bresette gave a tour of the facilities. Among the highlights -- oddly enough -- is a men's room- equipped with dual flush toilets.
"One of the humorous things about studying this kind of topic is you can talk about dual flush toilets and waterless urinals in polite company," Hoffman says.
Bresette says it saves a little water to pull the lever up -- it uses .8 gallons instead of 1.6 gallons if the flush is pressed down.
"It's pretty intuitive," he says. "I think this is the more culturally challenging issue for some people is a waterless urinal. People immediately think, 'Oh this is gonna stink.' But it doesn't smell. You can't smell it right now."
That's as long as the filters get changed regularly. In construction, as in other arenas, green manufacturers have sometimes had to contend with the perception that their products are inferior. Plumbers unions have opposed waterless urinals. Nonetheless, the sector for green building products -- paint, wallpaper, windows, flooring -- is burgeoning.
That sector was practically non-existent in 1993 -- when the U.S. Green Building Council got its start. The USGBC created the Leadership in Energy and Environmental Design or LEED program. Hoffman gives them a lot of credit for helping create demand.
"They created a cache around the LEED certification," he says. "And they got people to want to do this as a marketing pitch -- and I think that was really a stroke of genius to get a rather inertial industry to start to shift."
Certified buildings get a plaque for prominent display. And if you already know all of this -- it's a sign of the brand recognition LEED has developed. Hoffman says he thinks this is now key to attracting top students.
"College campuses are all starting to go this way," he says. "If you want to keep up with the Joneses, you kinda gotta do that."
The University of Michigan leadership agrees. This summer, they committed to seek LEED certification for every new construction project of at least $10 million. On the average $100 million project, they figure it will add 2 percent to the cost. This is a big endorsement of LEED. The university has a $2 billion construction program.
How LEED Works
LEED is set up like an arbiter of a sort of building Olympics. Projects earn points for various features. Use renewable cork flooring, for instance, get a point in the materials and resources category. Use paint that doesn't give off toxins -- score a point for indoor environmental quality. There are categories for water efficiency and energy. Pay the fees, rack up enough points, and win a basic, silver, gold or platinum rating. The Ross building achieved silver.
The company dumped its bronze rating -- and renamed it simply "certified."
"They're one of the most savvy non-profits when it comes to how do you reach out to the press, how to do marketing, and how to communicate their message," says Michele Russo, director of green research for McGraw-Hill Construction in Washington. "The word LEED meant nothing 10 odd years ago. And now that is literally like Kleenex is to tissues. I mean, you think of a LEED building and people think, 'Oh it's a green building.'"
Russo says the USGBC has been smart to network with people in every sector. And there's a growing army of professionals who now have LEED credentials.
Around 155,000 designers, contractors, consultants and others have studied up online using courses, then passed the test to earn the designation LEED Accredited Professional -- or "green associate."
Employ a LEED AP on a project and you get a point for that. The human infrastructure around LEED is far exceeds the number of actual projects. Since 2000, the USGBC says they've registered just a little less than 55,000 commercial and residential projects and certified around 12,000. So why are so many people getting credentialed?
As an industry observer, Michele Russo says the LEED AP gives her added credibility.
"It is nice to have on the business card," she says.
So many people want the professional designation that it's a big source of revenue. The USGBC brought in about $107 million last year. Some $42 million of that was related to accreditation.
And here's another reason for professionals to get familiar with LEED: In more and more places, LEED is becoming law. Part 2 of this report will look at how many lawmakers buy the idea that encouraging or forcing developers to build green is not only good for the environment, it's also good for economic development, and good for the health of workers who occupy those buildings. But there are those who say LEED doesn't deliver on all of those promises.
