LEED Pilot Credit 43 and Product Disclosure: Right Direction, Wrong Weighting

There's already been a lot of excellent debate around the new LEED Pilot Credit 43. I find myself agreeing with both sides! Here's where I stand in what may be the eye of the storm.

LEED is supposed to be about buildings--and market transformation

On the one hand, LEED is fundamentally supposed to be about designing high-performing green buildings, and product and material selection is one integrated component. It's not supposed to be about cobbling together a building out of greener products and materials. If the core purpose gets lost amidst the debate surrounding one material (yes, I'm talking FSC/SFI), we all lose.

On the other hand, LEED is at this point a major market driver for green building products. We need to use all the levers we can find to create truly sustainable manufacturing and sourcing if we're ever going to make it through these pivotal times into a vibrant, thriving, truly sustainable world. So we ought to use LEED for all it's worth in pushing real substantive improvements down through the supply chain.

EPA offers guidelines for broken CFLs, but will we follow them?

New, improved guidelines from the Environmental Protection Agency (EPA) about how to deal with a broken compact fluorescent lamp (CFL) are intended to take some of the mystery out of the purchase and use of CFLs. But by suggesting a response that borders on Hazmat lockdown, the guidelines may potentially add to consumers' uncertainties.

While CFLs have become more popular and less expensive in recent years, they still enjoy only around a quarter of the total market share for residential light bulbs--perhaps in part because of exaggerated reports about mercury toxicity and the difficulty of cleanup and disposal, some of which have prompted debunking sites like Snopes.com to clear the air. The average bulb contains around 5 mg of mercury, about 100 times less than an old-fashioned oral thermometer.

Still, mercury in any quantity should not be taken lightly, particularly in a home where children or pets live. Mercury in fish and other foods is a serious issue, but mercury vapor is even more toxic. Ingested mercury is not well absorbed by the body, while in contrast, inhaled mercury enters the bloodstream readily.

The new guidelines

The new EPA guidelines focus on preventing mercury inhalation. The key steps to safely cleaning up a CFL include the following.

10 Questions with 2010 Hanley Award winner Alex Wilson

 

Alex Wilson, the founder of our company and our current executive editor (i.e., my boss), is being named the 2010 Hanley Award winner in a special event here at Greenbuild 2010 tomorrow. In recognition of this achievement, and to better understand how this innovative, always-curious visionary looks at the world, I recently asked him 10 questions. Here's the conversation.

Congratulations on being the 2010 winner of the Hanley Award. How would you sum up your feelings on this honor?

Thanks Tristan. It's a tremendous honor--and an honor for all of us at BuildingGreen. EBN, GreenSpec, LEEDuser and our other products are all group efforts from the whole company. I'm truly humbled to receive this award.

What are your thoughts on following Ed Mazria, FAIA in winning the Hanley Award?

That makes it even better. I have tremendous respect for Ed and what he's done to engage the design community as well as governments in the goal of reducing our carbon footprint. I knew Ed, though not well, when I lived in Santa Fe in the late '70s, and I have a well-worn copy of his Passive Solar Energy Book in my home library. He is a pioneer in the true sense of the word, and I'm deeply honored to be following Ed in receiving the Hanley Award.

You've built your reputation in part on taking stands on issues like dangers of treated wood, brominated flame retardants, and the global warming impact of some insulation products, while drawing attention to cool new ideas like passive survivability. What's a stand that you've taken that you wish had caught on more?

Passive House in North America

Posted March 31, 2010 2:11 PM by Alex Wilson

Our April EBN feature article--"Passive House Arrives in North America: Could it Revolutionize the Way We Build?"--went online today. This was a fun article to research and write, because it put me in touch with my low-energy building roots. Until digging into the history of Wolfgang Feist's German Passivhaus standard, I hadn't realized that this building system really had its origins in North America--with the passive solar energy and superinsulation movements of the late 1970s (back when I got involved in this field while working in New Mexico).

Feist combined passive solar and extraordinarily well-insulated building envelopes to create buildings (both residential and commercial) so energy efficient that they can be heated using ventilation systems with small, 1,000-watt, in-duct electric heaters. Feist credits Amory Lovins of the Rocky Mountain Institute with this idea--that by investing in the building envelope, heating and cooling systems can be downsized dramatically. Energy loads are so small that buildings can be made net-zero-energy by installing rooftop PV.

Germans are known to value precision, so it is little surprise that the Passivhaus standard is highly quantitative, rigid, and performance-based. In bringing Passivhaus across the Atlantic and creating the Passive House Institute – U.S. (PHIUS), German-trained architect Katrin Klingenberg adopted the German standard exactly, retaining the 15 kWh/m2/year (4,755 Btu/ft2/yr) standard for heating, the same standard for cooling, a total primary energy consumption (including lighting, appliances, and plug loads) of 120 kWh/m2/yr (38,000 Btu/ft2/yr), and an airtightness standard of 0.6 air changes per hour at 50 pascals of pressure difference across the envelope (0.6 ACH50).

What I like about Passive House is how clear it is. The energy consumption and airtightness targets are spelled out precisely, leaving very little room for ambiguity. And those standards are really rigorous. If a house meets the Passive House standard it will be one of the most energy-efficient buildings in the country--period. As noted above, taking such buildings to the next step--making them net-zero-energy--is relatively easy.

The problem with Passive House is that same rigidity. The Passive House requirements could be tweaked, I believe, to make it work better in North America and for existing buildings. Background on these ideas is covered in the EBN article, but let me get right to a handful of specific recommendations. I'll look forward to comments about why these suggestions do (or don't) make sense, what I'm missing, what else could improve Passive House, and any other comments you might have.

Is LEED on Track to Save the World?

Posted November 30, 2009 5:09 PM by Nadav Malin

Rob Watson recently published "Green Building Market & Impact Report," his second annual report on the impact LEED is having in addressing environmental problems. The report highlights the continuing remarkable expansion of LEED: 2009 registrations for new design and construction projects in the U.S. may actually exceed total new construction starts! (This is possible because projects don't typically register when they start construction, and a flurry of projects were registered just before the requirement to use LEED 2009 kicked in, to keep their options open.)

Watson takes note of the shift from whole building construction to Commercial Interior tenant fit-outs (CI) and Existing Buildings: Operations & Maintenance (EBOM) registration and certification. And he compares 2009 certifications to registration numbers from 2006 and 2007 to see what fraction of projects are making it through the system. (In this analysis he assumes a three-year registration-to-certification timeframe for all except LEED-CI projects, for which he assumes two years. I would have given EBOM projects a shorter turn-around as well — in our market analysis for LEEDuser we assumed 18 months.)

Analyzing certification and registration trends is not Watson's main point, however. His focus is on the environmental benefits that follow. And that focus is what really caught my attention. I'm thankful he's taken that on, because it's so easy to forget what LEED was created for in the first place.

So, how is LEED doing at achieving its original goal? Watson explores this question category by category, looking at numbers of projects in each of the various rating systems that have achieved certain credits.

Green Economies of Scale (post-Greenbuild ruminations)

By the end of Greenbuild, I was exhausted/troubled/elated with all sorts of conundrums swirling around in my head — not to mention a few partly written blogs, abandoned in favor of the next conversation...

... I had wanted to write about the 'executive roundtable' that happened that Wednesday — and responses to the twitter-submitted question "what single thing would have to change to make buildings actually regenerative?" (as in, way past 'less damaging' — past neutrality, even). I was encouraged to hear the execs express what I see as core issues (summarized and/or quoted below — no, I didn't record who said what):

  • Waste and consumption is ridiculously cheap. If energy costs go up to the tune of $150/barrel for oil (or on-site renewables became radically cheaper), and/or if a cost is attached to emissions (not just air — also sewer and solid waste), we could get there.
  • Our financial accounting systematically discounts the future. "We're trapped in a paradigm of net present value (NPV) — one of the worst tools known to man.... We need a new tool — 'Net Future Value'... and to start to reconceptualize buildings to see them as multigenerational assets."
  • Corporations have to focus on shareholder's financial return above all else. Yes, the technology is there to do zero energy buildings but "for a profit making business with shareholders expecting a return they cannot generally be duplicated over and over."

On the last point, the phrasing I found interesting — because later they were asked how to tell green from greenwash — and one of them said "you'll know a business has credibility when they stop talking about one-off projects and demonstrate [that performance] across the board."

I put these two quotes together, out of context, because what I think it points to is that if we're really going to take green to the scale that is needed, we can't kid ourselves that we can do it all within the current economic rules-of-the-game that stack the deck against stewardship and the future. (Don't get me wrong, the Green Building movement is doing an incredible job within this context, but that doesn't mean the system works — rather, it's a testament to the smarts, creativity, passion, and perseverance of folks making change despite an imperfect market designed to thwart their best efforts).

At another session, the speaker reminded us that our economic system is a social construct — it's a story we've created, and we can revise that story. Let's not forget that, because ultimately if we don't find a way to align individual and corporate financial success with the wellbeing of future generations and the environment, we'll find ourselves without either.

Confronting Water Shortages — Post-Greenbuild Travels in Southern Arizona

 

(click photos for larger versions)
Greenbuild in Phoenix was the usual high-energy panoply of educational sessions, new product introductions in an ever-larger trade show, networking events, and — the reason our company sends so many of us — opportunities to promote our green building information resources.

But this year, I was also looking forward to some vacation time following the conference. Jerelyn and I took five days' of vacation after Greenbuild to explore southern Arizona and celebrate our 25th anniversary. As day transitions to night on the flight back east, I reflect on that time.

On Saturday morning, we traveled southeast from Phoenix, past Tucson, to the Hacienda Corona do Guevavi bed & breakfast in Nogales, Arizona, just a stone's throw from the Mexican border. The region is rich with wildlife and draws thousands of birders and others from throughout the world each year. Along with hundreds of bird species in the canyon oases sprinkled throughout Cochise Country (we saw about 60 species in our travels) are such exotic mammals as coati, ringtail, antelope jackrabbit, collared peccary (javalina), cougar (mountain lion), bobcat, and maybe (at least before the border fence) the rare cats ocelot and jaguar. Other than the antelope jackrabbit, we didn't see any others of those mammals, but it was great imagining them watching us from hidden spots rock ledges during our daily hikes.

On all of these hikes, at least when I wasn't trying to identify another new bird species, I spent time thinking about — and discussing with Jerelyn — the water crisis facing this region.

The Great Passivhaus Face-off

The low energy use of the first Passivhaus in Bremen, Germany, is surprising, especially since the house has neither solar collectors, nor a PV array, nor a boiler.
I've been a big fan of building scientist John Straube for a long time. And equally as big of a fan, for just as long, of deep-energy engineer Marc Rosenbaum. To see the two of them face off over the ultra-low energy use Passivhaus concept is a green-building wonk's dream.

Our always enlightening (and often entertaining) sister site, greenbuildingadvisor.com, has a pro/con pair of articles under the banner "Does Passivhaus Make Sense Over Here?"

Gold.

Start with John Straube's "con" article first: "Comparing Passivhaus Standard Homes to Other Low-Energy Homes." It handily describes the Passivhaus standard as it goes along, in case you're not familiar with it.

Then read the "pro" rebut, "In Defense of the Passive House Standard," by Marc Rosenbaum and David White (who I don't know, but am going to keep my eyes open for).

Passivhaus or not? Yes and no.

Why are people drawn to design inspired by nature?

I received an email from a Design student at Kingston University (London) writing a dissertation on "why people are drawn to design inspired by nature." Three questions were sent; I went overboard answering the first one, and basically wussed out on the second two. I'd be interested in your takes on this highly subjective stuff, and will be sure to let our dissertation author in on the discussion.

1. Why in your opinion are people so drawn to design inspired by nature?

2. What in your opinion is the finest example of design inspired by nature in the field of product and furniture design (my course)?

3. Do you think there are psychological benefits to design inspired by nature, and what do you think they are?



1. Why in your opinion are people so drawn to design inspired by nature?

I don't think everyone is drawn to design inspired by nature. Some like Le Corbusier's buildings at their boxiest, and contemporary glass and aluminum offices and homes, and Danish Modern furniture, while others like nature-inspired design... simply because they do. There's no accounting for taste. I know that speaks to the shallowest part of peoples' immediate and visceral reactions to aesthetics, but I think that most of the time — especially in this day and age — that's all there is to it. It's certainly not true of everyone, but most people in these harried times never have any need or desire to consider why some fashion appeals to them while some other fashion doesn't. It is what it is, and there are ten thousand other urgent things to attend to. If pressed, they'll tend to latch onto any available notions that support their position without actually considering them. Look to politics as an independent example of that. Trying to detangle rationalizations from pure impulse is a tricky business. (But it would probably be a much better world if more people tried.)

Stimulus-Funded Green Jobs = Left-Wing Conspiracy

Posted September 23, 2009 2:48 PM by Mark Piepkorn
Related Categories: Op-Ed, Books & Media, Politics
 

Over at GreenBuildingAdvisor, veteran journalist Richard Defendorf combined his abiding interests in green building and politics by taking a look at a Fox News Forum opinion piece from the policy director the conservative advocacy group (natch) Americans for Prosperity. It contained gems like this one:

"Most green jobs consist of hiring low-wage workers with caulking guns to weatherize buildings. We are trading away high-wage, high-value manufacturing jobs for these green caulking jobs. Any time you spend billions of dollars you will create some jobs, but the key question is, what the cost is when you divert resources from higher-value activities?"

Defendorf had the audacity to respond with thoughtfulness and logic. Take a couple minutes to read it: Stick 'Em Up, I've Got a Caulk Gun!
