Green building has many elephants in the room and thanks to the current state of the economy, this is a big one: will green building suffer because of the current state of the economy?

The problem with trying to answer this question is that it all comes down to

The road to market-wide green buildings?

definitions: what do you consider to be a green building? Does it need to be certified by a third party operation? Are you talking about all markets - commercial, homes, mixed use etc.?

Assuming you can answer the definition question, another one immediately presents itself: how do we measure how green buildings are doing? Is there any way to realistically measure the buildings that are putting off plans, and then how green building is a factor in that?

I cannot answer these questions without doing a lot of research with time I frankly don’t have. But in the end, it seems like there are two groups out there:

1. The group that thinks yes, green buildings will take a hit because they’re more expensive.

and

2. The group that thinks green buildings are actually more valuable because they cut down on energy use and electricity bills, and will hold their value better in future markets.

Which group do you belong to? Comment on my new poll at right, or tell me more below, to let me know!

Want some inspiration in our current housing crunch? I’ve had the good fortune to tour a couple Central District projects designed and built by the architect/developer duo of Brad Khouri and Graham Black. And the back stories are just as impressive as

Urban Canyon

the finished products.

To start, both Khouri, who runs b9 architects, and Black, owner of gProjects, bicycle to all their projects and strive for designs that integrate with the neighborhood’s character and scale. They are big fans of the design review process, which they say encourages better and more profitable projects.

While Khouri designs efficient and smart use of space for these human-scale homes, Black concentrates on salvaging building materials for reuse. A couple projects, for instance, use reclaimed wood from old Fort Lewis barracks that dates to the 1930s. And Black employs all his own builders in order to maintain quality and pay competitive rates. The final result are modern homes that fit and work–efficient on resources and high on function and style.

And with the market bearing down, the best inspiration may be that the homes are selling. There’s plenty of evidence to build green, but clear market success will most quickly drive more quality sustainable projects.

AIA Seattle is hosting a case study and tour tomorrow at the Urban Canyon (pictured above), Khouri’s and Black’s latest project at 19th and Pine, which is the first 5-Star Built Green multi-family development in Seattle. The Alley House, a Madison Valley urban infill residence seeking LEED Platinum, by Urbanmix and Cascade Built, will also be highlighted. Check out www.aiaseattle.org as space is limited.

The panels are marketed towards offices. According to Solyndra’s Web site, wind blows through the tubes so no rooftop anchoring is required, making them a cost-effective business solar solution (wow, what a mouthful!) So far, the company says it has $1.2 billion in multi-year contracts in Europe and the U.S.

We're not in Kansas anymore, Toto!

Do you really want this under your floor?

Essentially what it documented is when you have a vented crawlspace in a warm, humid climate the floor framing is prone to rot. In this climate, your house is often being mechanically cooled (which also cools the crawl space), warm, humid air enters the crawlspace through the vents and condenses on the cold framing members. Eventually the house may develop rot and mold problems. I agree in this climate scenario that closed crawlspaces are a great idea to maintain structural integrity. Also, if there are ducts in the crawl space, any duct losses are now contained inside the building. Note the radon differences between the two crawlspaces and keep in mind that Princeville, NC is considered a low risk radon location by EPA.

Since this construction method is catching on nationally, WSU Energy Program received funding to test houses in our state to determine if this is the way to go in the Pacific Northwest. Here is a description of the results from David Hales, Lead Researcher on this project:

nbec-logo-sq-3color

“We’ve recently completed research on sealed and vented crawlspaces in the Pacific Northwest. The results are not yet published but based on our experience with four homes in Vancouver and four in Moses Lake that we monitored for about 18 months, the sealed crawlspaces (without supply air but power vented to the outside) maintained very stable temperatures through the entire heating season in the 55 to 60 degree range. The crawl should be kept negative to the house. Based on tracer gas studies we found that in the typical vented crawl, approximately 40% of the house air came from the crawlspace in the winter. By power venting a sealed crawl (50 cfm 24/7 in 1000ft2) less than 6 percent of the house air came from the crawl. Because of higher dilution rates and additional factors radon levels at both sites were less than 2 piC/l in the vented crawls but at the same sites radon levels were from 12-16 piC/l (EPA states radon mitigation should happen when a house has radon levels of 4 picocuries per liter or higher) in the sealed crawls. From an energy standpoint there is a small penalty overall for the sealed crawl that gets worse if you actually add supply air to the space. If a cold floor is your primary concern, I would insulate the floor and not provide heat to the crawl. Over the life of the building this would be the most cost effective way to maintain a warm floor.

Based on this research we are preparing to make a recommendation to the Building Code Council that would allow conditioned crawls under some circumstances. However, in most areas of the Northwest they incur an energy penalty and an added expense that I don’t think is really justified. Some jurisdictions have been allowing them but a strict interpretation of the WA State Energy Code does not. I believe that if they are done they should be power vented to the exterior and should not have conditioned supply air directly introduced. I also think they should not use fiberglass batts for the perimeter wall insulation. Radon mitigation is a must.”

The power vented crawl may have an advantage from an IAQ perspective because as our testing showed, it is possible to substantially reverse the winter time stack effect and decouple the house from any contaminants that may be in the crawl. The problem with this is that it requires the continuous operation of an exhaust fan. If the fan fails and is not replaced, the IAQ may actually become worse because the air now entering the house does not benefit from the passive dilution that takes place in the vented crawl.

So it seems that from an energy efficiency and indoor air quality perspective unvented crawl spaces are not a benefit here but let’s not forget about the ducts. If you have ducts in a crawl space they leak - it’s just a matter of how much. Here’s a radical concept. Instead of moving your house around your ducts, why don’t you design your house with the ducts inside your house? Then duct leakage is not a problem. If you can’t get them inside your house make sure they are sealed well (with mastic, NOT duct tape) and test them with a DuctBlaster.
 
Finally, here is a statement we hear a lot: “I have a water problem in my crawl space so I’m going to seal it up and heat it.”  Fix the water problem or you will end up with a science project under your floor.

Readers, do you agree with Gary?

This is the water calculator!

often successful). Yes, I know they don’t always represent the entire picture…. But heck, they’re fun.

So today, my calculator of choice measures a “water footprint”. The calculator, presented by a New York-based project called H2O Conserve, asks you a number of questions. You answer and BAM! Your water use gets compared to that of the typical American, all accompanied by handy and sometimes cute graphics. My favorite is the one that accompanies the ‘I don’t brush my teeth’ answer. (Which I do, by the way. I just wanted to see the graphic….)

I am below the national average, but just barely at an individual water use of 1,072.20 gallons per day. Written out, that seems staggering.

The calculator also offers handy suggestions of how to decrease my water use, but some of them are just plain against my cultural habits. For example, it says I can save 10 or more gallons of water a day by not flushing the toilet and “letting it melow” instead.  Somehow I don’t think that would fly with my colleagues at work.

But some of the tips are also interesting. For example, the calculator says I can save water by getting an efficient dishwasher, rather than washing dishes by hand.

I first wrote about the project last December here when Noland Homes was the

builder on the project and planned to develop it at its own cost. A lot has changed since then: namely Noland dropped out and Howland Homes came on (and will develop it at its own cost). But the project has finally broken ground and, as Brad Liljequist, zHome project manager for the city of Issaquah, says in the project’s inaugual blog post (yes it has a blog here) it “takes my breath away a little bit” to be at this stage in the project’s life.

zHome has a nifty Web site that can answer all and any of your questions from what materials are being used to how they’re doing it to how to buy into it. For more information, visit it here.

This solar panel from the groundbreaking comes wrapped in a bow!

The latest rendering

This product could be yours!

So when I got a press release for the Brondell Swash Ecoseat, I wasn’t surprised but rather perplexed. The Ecoseat bills itself as an ”ecofriendly” way to save trees. Rather than flushing 100,000,000 rolls of toilet paper worldwide per day representing 55 million trees each year, the press release says, you can do simply buy this product and wipe all that eco-guilt out of your life.

The product is a battery operated “dual wand seat with an integrated bidet which features adjustable water pressure (for a refreshing feminine and posterior wash) and push button controls.” In other words, it uses water rather than paper to clean you off.

Is it really environmentally friendly or are the company’s claims eco greenwash? In June, the Washington Post carried a story by Blaine Harden about how energy use in Japan is soaring and how one major factor is high tech toilets that “warm one’s bottom, whisk away odors with built-in fans and play water noises.” They also play relaxation music like “Ave Maria.” But they also consume energy at an alarming rate because they are always plugged in. The article says people are also using the toilet more, because it’s a comfortable space. Some even get addicted to it.

Here in the U.S, old fashioned toilets are getting more and more water efficient.

This is what your toilet would look like

Recently at a water conference i attended, Water Expert Roger Van Gelder told attendees that new super efficient systems using 1.0 gallons per flush or less can be just as strong or stronger than older models that used seven gallons. The water use of a toilet doesn’t make it a better toilet and stronger toilet, he said, instead it’s the product’s systems that do the job.

But with all toilets, he said, you have to actually test the toilets to see how well they work. “Anything that you get, you can’t really believe what it says on the box.” 

So how about believing the Swash Ecoseat’s box. It is battery operated so it doesn’t plug into the wall. But it still uses energy. What do you think readers, is it greenwash or a green solution?

Busy, busy times!

Growth Alliance in downtown Seattle, to a panel discussion (that I moderated) in Bellevue, and back to our offices in Pioneer Square to write up the story. Whew.

In case you missed both those events (and the recommendations put out by the Western Climate Initiative to boot) here is a rundown for your viewing pleasure:

The Quality Growth Alliance. Anyone remember Reality Check in April? The huge event that got 250 big-wigs playing with Legos? At that event (DJC story on it here), I spoke with Jim Potter of Kauri Investments who told me it was a great planning exercise as long as the results didn’t fade away into the sunset. Well the alliance is the attempt of prominent groups - from the UW’s College of Architecture and Urban Planning to NAIOP - to make sure the results stick around and influence future planning policy. More info in my story in today’s DJC or at their Web site.

The Panel Discussion. In case you missed this one, it was a lot of fun. Hosted by SMPS, panelists represented various fields of the AEC community (architecture, engineering, construction) and were Eric Anderson of MulvannyG2, Jeffrey Cox of Triad Associates, Rae Anne Rushing of Rushing and Yancy Wright of Sellen Construction Co. Among some of the interesting tidbits:

• Collectively, panelists said sustainable or green design is changing so quickly, that as soon as you read about it, it’s old. If you want to know what’s going on you need to work to educate yourself. This is true for everyone, and especially for marketers.
• Marketing and public relations professionals, they said, need to be really careful about sounding really stupid. Oftentimes they (and I incidentally) get press releases that virtually make no sense. If you’re going to write about green systems or projects, understand it, otherwise you run the risk of major embarrassments (I can’t tell you how often I get press releases that tell me a product will get me 10 “Leeds” points).
• Green building doesn’t have to be more expensive if you start from the beginning and have the right leaders on board. If you start thinking about integrative design and green systems midway through a project, there’s a good chance it’s going to be more expensive.
• Everyone needs to be on board with green building, even those who have been in the industry for many years and are hesitant to change the way they work. Panelists said they need all disciplines at an eco-charette and that bringing and open mind really, really helps.
• Definitions aren’t clear and because everyone has different definitions…. it’s hard to understand what a word, be it ‘eco-charette,’ ’sustainability’ or ‘integrative design,’ means to a specific person. Define those definitions for your project, or your company.

Western Climate Initiative. And don’t forget yesterday’s announced recomendations by the Western Climate Initiative for a regional cap and trade system. If you want to learn more about this one, read the Seattle Times or the PI.

Also, if you’re looking for an interesting way to fill your Thursday evening, Patrick Bellew of Atelier Ten will speak at the downtown Seattle Library at 5:30.

That’s all for today folks. If I don’t thank you enough, thanks for reading!

 “If you’re involved in sustainable design and (not) addressing issues of equity and justice, you’re not involved in sustainability.”

Arup's Treasure Island project in San Francisco

He defined social equity or social justice as considering the impact your building and designing choices have on other humans. So instead of putting on that green roof, you consider how the extra steel needed to reinforce the roof will affect the lives of the people who will mine the steel. Basically you look at your choices from an all inclusive roundabout way.

It takes a lot of thinking. And for those people just entering into green building or sustainable design, it might be too much work to add on (at the beginning stage of the game).

But intrinsically, is Lawrence right? Can you, Mr. Architect or Ms. City Planner really call your work sustainable if you don’t consider all the different people your choice will affect both in the past and in the future? Or is it just too much to handle?

The question in itself is fascinating, and one that I, by my lonesome, cannot answer. What do you think?

P.S. (Lawrence’s resume could make most people’s eyes widen. He has been a former DPD planning director, UW professor, adivsor to the Clinton Administration’s Council on Sustainable Development, the United Nation’s Habitat II, the Brazilian President’s Office, the British Prime Minister’s Office, not to mention currently running Arup’s sustainable urban development globally.)

For more information, it turns out King County Executive Ron Sims has already tapped this topic in a keynote talk of his own. Read the press release. I don’t know much about the Holcim Foundation for Sustainable Construction, but it has some interesting definitions here.
