The need for LEED: We can make buildings more energy efficient

Monday, August 10, 2009 | 6:00 a.m. CDT; updated 8:22 a.m. CDT, Monday, August 10, 2009

“Sustainable development is sexy.” Thus reads a T-shirt sold by a public-health group at Columbia University. And, despite being generally against quirky-statement apparel, I could wear that slogan all day long.

Sustainable development, as popularly defined by the United Nations Brundtland Commission in 1987, is development that meets the needs of the present without compromising the ability of future generations to meet their own needs. In less diplomatic words: Stop bogarting resources or your grandchildren will live in trash.

We often hear about sustainability in reference to gas-gobbling cars, but they’re not the only culprit: Buildings account for 39 percent of energy use in the US, as well as the 30 percent of our waste output. “Green” construction is one hot method of downsizing such numbers, and buildings tagged with various seals of environmental approval have proliferated over the past decade.

Unfortunately, not all those seals were created equal. (Some are more nominal than others.) But there is a trustworthy, healthily stringent rating system that comes from the US Green Building Council. Their green standard is familiarly known as LEED, an acronym for Leadership in Energy and Environmental Design.

Buildings that get a LEED certification use reduced amounts of electricity and water. Their proprietors commit space to recycling. Their inhabitants work or play in fresh air and daylight. And their overhead is (sometimes astronomically) reduced. Such green building has started in Columbia in recent years, but we could certainly use more. We have, you might say, an increasingly pressing need for LEED.

The USGBC’s rating system has been in effect for about 10 years, and many places adopted early. Los Angeles, for example, can champion hundreds of projects. In places such as Baltimore, LEED recently started doubling as the law; if a builder doesn’t adhere to those green standards, no permit will be issued. Show’s over.

Meanwhile in Columbia, only one building — Wabash Station — has been certified, and there are only six more projects registered as seeking verification, according to a database on the USGBC Web site. Granted, these numbers aren’t absolute; the two fire stations set to be certified under the watch of architecture firm Peckham & Wright don’t pop up in the list of results, for instance. But we’re looking at a number that can be much improved regardless.

As Nick Peckham pointed out in a recent conversation, at some point during any talk about green building, one question will inevitably pop up: How much does it cost? And that, according to him and many others, doesn’t have an easy stock answer.

Zealous advocates cite numbers that show you can build to LEED standards at almost no extra cost, if you build carefully. Another figure that gets thrown around a lot is 6 percent, as in addition to your premium. But in some cases, such as completing renovations on old buildings unsuited to green fittings, many more dollars can be in play.  

There’s also the cost-recouping to consider. In the case of a banking headquarters in Amsterdam, for example, going green saved the business $2.9 million per year on operating costs. According to the EPA, a LEED-certified building will typically use 30 percent less energy and 30-50 percent less water; that’s a no-joke chunk of the monthly bill.  

And there are less obvious means of payback, too. I know it sounds a little cosmic-hippie, I’m-gonna-name-my-kid-Rainbow, but people are happier and perform better in buildings that funnel in the air and sun from outside. The Amersterdam HQ also saw 15 percent less absenteeism, and similar results have been found in other case studies; that adds up in terms of what would have otherwise been lost productivity.

Where schools are considered, one study conducted on the so-called “daylighting effect” showed that students exposed to the most natural light scored up to 18 percent higher on tests than those exposed to the least. That could be a bump from C to A.

Peckham pointed to this kind of non-numerical cost-reward balancing in discussing the Eco Schoolhouse at Grant Elementary School that his firm completed last year. The kids, he said, are learning to live sustainably at a ripe age; recycling becomes a basic alongside arithmetic. And, as he points out, the heart-on-the-sleeve crowd might answer the cost question with another: “Trashing out the planet has one hell of a price tag, doesn’t it?”

Still, Peckham and everyone else know budgets are limited, and that’s especially true at the moment. One idea that’s worked well elsewhere is providing tax-credits and incentives to help cut LEED costs. This idea was raised in the 2007 Columbia Vision Report, as part of a larger “visioning” plan meant to make CoMo’s future green and otherwise bright, but such measures have yet to be approved or implemented.

If all funding fails, one upside of LEED is that it still works as a fine green how-to guide, regardless of whether you follow enough of their specifications to be certified. And getting even a little sustainable development on board is a fine way to get some green-sexy back, believe me: I wouldn't wear the T-shirt otherwise.

In our celebrity driven, sound bite oriented, opinion as news and junk as science world, hype is like the sun.

A little bit of hype can be a good thing, especially for emerging technologies, or in this case "iffy" green stuff by helping them grow. A lot like weeds - springing up everywhere so as to be included in the latest societal dialogue.

“Green technology” is often more overhyped fairy tale than reality. Ditto for "green jobs", "green lifestyles" and "going green T shirts".

The only thing "green" working overtime is the political marketing and social media aspect.

God bless the marketing efforts that've made the idea of "green" more sexy. Without people working overtime on this fairy-tale message, there is a huge chance that nothing in our entitlement-driven society will ever change. Are we really interested in living in a stagnating world that only gets worse, simply because we refuse to believe that new ideas are all hype and no reality? Sustainability is no fairy tale, it's a moral imperative. Get with it.

Sustainability, as in building more efficient buildings and lessening the need for fossil energy, will become quite a bit more important as India and China strive to become nations of Western-style consumers. Our energy supplies are being stretched thin meeting the needs of one billion consumers, and will be inadequate to support three billion. Very high prices, shortages, and resource conflicts are likely in the near future unless we take action to reduce our primary need for fossil energy, and programs like LEED can help do that.

My husband and I are building a green home, which means absolutely no bigger than necessary and sited to make the most efficient use of passive solar. I'm not sure we will end up LEED certifying, but we will be green from the ground up.
For anyone who has any green leanings, this is your time to reshape the housing market according to your vision, and many green aspects to a building project take forethought more than money. Check out 8 steps to siting a green home, written by our architect, Della Hansmann, at
