It's taken awhile to go from touring green homes to actually living in one, but for Becky Chan, it's been well worth it. Chan has been blogging her two-year journey, and says she got hooked on the idea as a result of visiting "homes built with recycled or reclaimed materials to reduce waste, homes with green roofs and living walls to slow stormwater runoff and filter pollutants, and the first net-zero-energy house built in Seattle.”
Now, those who plan to partake of this year's Green Home Tour on April 27, co-produced by the NW EcoBuilding Guild and Built Green of King and Snohomish County, will get to see her "deep green" remodel.
Parie Hines, LD Arch, designed the remodel and was impressed by Chan's focus on combining deep green ambitions with "thrift." Hines conservatively estimates a final construction cost of $150 per square foot (the original goal was $135 per square foot), pointing out that the new remodel includes high quality (and expensive) windows and infrastructure, while keeping finishes and details simple (and less expensive).
Chan's "Blue View, Green Built" net zero energy remodel is one of several in the North Seattle tour quadrant, and includes SIPS construction (3 walls were replaced with SIPS), rainwater harvesting, natural materials, salvaged/reused materials, solar PV, ductless mini-split heating, triple glazed windows, and a heat pump water heater. The home is also an example of deconstruction.
After the tour, she wanted to learn more, so she joined the NW EcoBuilding Guild, the nonprofit that has organized the free tour for three years. She also attended a net zero energy workshop conducted by Sustainable Ballard where she met Ted Clifton, TC Legend Homes. Clifton had built the net zero energy house Chan had so admired in the 2011 tour. She eventually hired him to conduct the remodel. She then bought a home, with remodeling in mind, that was conveniently located to services she knew she would need, proactively reducing her carbon footprint.
For those responsible for programming, funding, or otherwise involved with green building education, the hope is that this education translates to implementation. Chan's deep green remodel is a great example of how this works.

The following post is by DJC staff:
Harbor Urban says people are starting to move into the GreenHouse Apartments at 3701 S. Hudson St. in Columbia City. The LEED gold project has one notable feature: irrigated garden plots for each resident on the roof.
Harbor calls it “roof-to-fork urban agriculture.”
There’s also a greenhouse on the roof and a communal space for dining, as well as edible trees and shrubs scattered throughout the property. The rooftop plants absorb rainwater and reduce runoff, and the soil and vegetation help insulate the buildings.
The site is near the Columbia City light rail station and the farmers’ market.
Harbor said half of the units were leased before the building officially opened.
Harbor Urban, LLC is the developer, Exxel Pacific built it and Runberg Architecture Group was the architect. The landscape architect was Hewitt and the structural engineer was CPL. LEED consultant was O’Brien & Co.
Martha Barkman, director of design and construction for Harbor Urban, said, “We spent a lot of time early in the entitlement stages to make sure it was something that would be accepted by and truly fit into the existing community, which is a unique treasure.”
Harbor said GreenHouse is the first new market-rate apartments in Columbia City since 1969.
GreenHouse has 124 units, 20 percent of which are designated affordable under Seattle’s Multi-family Tax Exemption program.
This post has been updated since it was first published to name additional project team members.
Sara Strouse, an architecture grad student in the WSU School of Design and Construction, has organized a design competition — there’s no contract at the end but the winner gets a $3,000 prize — to find creative ways to reuse waste material when the old SR 520 floating bridge comes down in 2014.
A press release from WSU about the competition said replacing the bridge is expected to create enough waste material to fill 67 Boeing 747s.
Strouse said as her final design project for school she wants to see if having a competition will get more people thinking about adaptive reuse — and get a little more attention for her thesis. She hopes to get between 50 and 100 ideas from design teams and individuals.
Submissions are due Aug. 15.
Strouse said she initially thought she would come up with ideas for reusing the bridge materials but she wanted to reach a broader audience and get an up-close look at how design competitions work so she decided to launch the contest. It has been a struggle to get sponsors and design the website herself, but it is giving her an opportunity to network with people and companies in the Seattle design community, where she eventually hopes to land a job. She graduates in December.
Her father is a local architect, William Strouse of KSI Architecture and Planning.
The contest sponsors are NBBJ, KSI Architecture and Planning, WSU School of Design and Construction, and Kiewit/General/Manson, which is the bridge project contractor.
The new bridge is scheduled to open in 2014. After that, the old bridge will be removed.
Paul Hirzel of the School of Design and Construction said, “Infrastructure is of big interest in the U.S. right now, and encouraging the reuse of an existing structure versus demolition contributes to sustainability measures that are becoming more and more critical.”
The jury includes WSU graduate and architect Robert Hull.
For more information on the competition, see www.rethinkreuse.org. Winners will be announced by Peter Steinbrueck at the Seattle Design Festival Sept. 21. Winning entries will be displayed at the AIA Seattle Gallery from Sept. 18 through Oct. 26.
The following post is by Brad Kahn, president of Groundwork Strategies. He manages communications for the Bullitt Center project.
The roof of the Bullitt Center on East Madison Street is under construction now and all the structural elements are in place.
Today President Rosen Plevneliev from Bulgaria, who is a former real estate developer, will tour the Bullitt Center as part of a trade mission to Seattle.
After campaigning for president on a platform that included energy efficiency in buildings, Plevneliev will be in Seattle today before heading to the NATO summit in Chicago next week. His visit to Seattle is focused on international trade and economic development. In particular, he is interested in learning about green building and clean energy technology, which is why he is touring Bullitt Center, the world’s greenest office building.
In the next few weeks, we will begin outreach to brokers to begin marketing office space inside the Bullitt Center. It will be marketed at rates comparable to new class-A space in downtown.
The HVAC system is going into the building, including the six-story composting toilet system.
McGivra Place, the park next door, now has a final design direction and the process is moving forward, with re-development expected later this summer or early fall. The park project is the first to pursue the Living Building Challenge for landscapes.
A compact, green-built “pod” home designed by Ann Raab of Greenpod Development of Port Townsend is open to the public at the GreenDepot site until April 29 from 10 am to 6 pm M-F, 10-5 on Saturday and 11-5 on Sunday. Workshops will be offered daily.
The pod was part of last weekend’s Green Home Tour sponsored by Northwest Ecobuilding Guild, featuring new and remodeled homes designed for low energy use and built with nontoxic materials.
Raab’s 450-square-foot pod is factory-built using all green products. It can be delivered to any city in Washington.
Greenpod’s Waterhaus model has a Kangen water system with adjustable pH for drinking and cleaning. It also has a waterfall and living wall.
Ann Raab said pods are meant to be low maintenance dwellings that are environmentally safe, healthy for occupants and “a joy to live in.”
The Waterhaus model uses multi-use furnishings, color, lighting and windows to make the living space feel larger. The waterfall and living wall are sculpted from metal by industrial artist Ray Hammar of Sequim. Michael Hamilton of Port Hadlock made the tables and benches. Seth Rolland of Port Townsend created the bathroom vanity from rock and fir. Wall textures are applied by artist Gail Miller of Whidbey Island. The interior is decorated with an exclusive line of organic fabrics by Suzanne DeVall.
The pods are built by Greg Barron of Greenpod Builders.
They are built to meet King County’s requirements for an accessory dwelling unit (ADU) and are aimed at people who want to downsize, age in place or care for family member in a separate unit. They also work as cabins, second homes, home offices and small commercial buildings. Pods can be stacked and configured to create communities. More information is at (800) 569-0831 or GreenPod.us.

When the Bullitt Foundation began work on the Bullitt Center, Denis Hayes, the foundation's president and CEO, had a clear vision that the architecture should be regionally relevant. Noting that buildings in Seattle and Phoenix are too frequently designed in the same ways, Hayes set out to promote the idea of a "regional vernacular" in architecture that draws on the environment surrounding Seattle for guidance. And in the Pacific Northwest, there is no environmental feature more prominent than forests, making wood a logical building material.
Add in the fact that when it comes from a responsibly managed forest, wood is among the most environmentally friendly building materials, and it is only natural that the Bullitt Center is a heavy-timber framed structure.
As the first commercial building to pursue the Living Building Challenge, the Bullitt Center team is working hard to meet all 20 "imperatives," as the requirements are known. Included in this list is an imperative focused on "Responsible Industry," requiring that "all wood must be certified by the Forest Stewardship Council (FSC)" or from salvaged sources.
With construction well under way, wood framing for the Bullitt Center has begun.
And anyone who has passed the job site on 15th & Madison has likely noticed the glued, laminated timbers, or "glulams" as they are known in the industry. Manufactured by Calvert Glulams in Vancouver, Wash., the glulams offer several environmental benefits, in addition to being stronger than traditional sawn timbers. First, they are from forests certified to the standards set by the Forest Stewardship Council, which is widely recognized to be the most rigorous and prescriptive benchmark for forest management globally. All wood for the project comes from within a 1,000-kilometer radius, as required by the Living Building Challenge. In the case of the glulams, the wood came from FSC-certified Douglas fir forests in Idaho, so the project is helping support a regional economy for wood from responsibly managed forests. And because the glulams are manufactured by combining smaller dimensional lumber, they reduce pressure to harvest larger, older trees that historically were needed to mill large dimension timbers.
Over the next few weeks, expect to see the Bullitt Center take its full form, as the six stories rise from the construction site. The project is on track to be completed later this year.
I've noticed a quiet trend over the last year: more and more teams are crediting each other on successful projects.
I'm not sure whether teams are actually collaborating more or whether they just say theyintegrated project delivery and more open bidding methods or if its culturally related to social media. But it's happening. More and more people I talk to are highlighting the importance of different team members.
Sustainable design is inherently related to integrating. The whole point of green building is to cut down on waste and redundancies. The idea behind collaboration and working together, is that you accomplish that goal more efficiently.
Just to give you a few examples:
In December, I went to the AIA Seattle's forum on IPD and wrote this story called "Form Right Team for Successful Construction Project." The story condenses a big theme from the event, which is that the team is the most important element in creating good IPD projects. Speakers said more effort needs to go towards selecting team members for IPD projects, but the lessons seem to be worthwhile for any type of project.
Dave Kievet, group president of California operations for The Boldt Co., said all sorts of questions about experience, work ethic and outside interests are asked when a company hires a new employee. But when a contractor is hired, very little time is spent on those issues. Instead, questions are about safety record, balance statements and licenses.
“You can have the best team assembled that can be absolutely destroyed by one bad apple on that team,” he said. “It's the people that deliver a project, not the companies.”
The forum also highlighted the importance of working together to move through negative situations. Barb Jackson of California Polytechnic State University said she often counsels her IPD teams to have "you suck meetings" so everyone can clear the air. It's better than dwelling on problems and letting them stifle a team, she said.
Last week, I toured this $56 million new water treatment plant in Anacortes. The teamFred Buckenmeyer, Anacortes public works director, said the camaraderie at project meetings is real. Matt Reynolds, assistant city engineer, said everyone has been fair with each other and works to solve problems when things go wrong, rather than place blame.
Brandt Barnes of MWW, the owner's representative and construction manager, said all team members took a partnering approach to the project that they will be proud of for many years to come.
Todd Pike, project manager at Imco General Construction, said the construction process in general is becoming more open, due in part to the influence of new contracting methods like GC/CM and design-build. But he said being open is a conscious effort at Imco. “You (can't) miss one person... It's a purposeful, intentional effort on all sides of the contract,” he said. “We don't have to have a design-build contract or GC/CM contract to reach out and have this positive, open communication with the owners and the design team.”Jan. 13 edition of the DJC here, I wrote about the "swale on Yale project." The swale is an innovative public-private partnership, in which Vulcan contributed over $1 million to a city stormwater treatment project. The swale, once comple, will treat over 190 million gallons of stormwater per year that currently flows straight into Lake Union. Jason Sharpley, project manager with SPU, said both Vulcan and city team members went out of their way to work together, and put the good of the project above anything else. Team members included KPG, KPFF, The Berger Partnership and Runberg Architecture Group.
Now, it's not like people have never talked about collaboration before. The difference is that more team members are talking about its importance. What do you think? Do you think this is a noticeable trend?
In February of 2010, I wrote this story about an office building in Georgetown that was constructed of reclaimed cargo containers. The owner, Jay Stark, said it was the first project of its kind in the country. I also produced this video-tour of the space at the time. Here is our story from Dec. 16 about the sale.
Now, nearly two years later, the space is for sale for $1.5 million. Sadly, it was a foreclosure. I
The slight upside is that it will be really interesting to see who buys the site when it sells. I recently spoke to Evan Lugar of Kidder Mathews, who is representing First Savings Bank Northwest on the sale. He said the bank has owned the property since August. He also said it's a tricky space to sell because it isn't typical retail or commercial and is unique. He's targeting creative businesses.
The building is made of 80 percent recycled materials by weight. The complex has two buildings, which are each made of six cargo containers that came from the Port of Seattle. They have halogen and fluorescent lighting, an efficient reverse-cycle chiller HVAC system, and windows with argon gas sandwiched between the panes for increased insulation. There is a rooftop deck with views of downtown Seattle and Mount Rainier.
Typically - the super green, innovative projects that have been built have been created with the intent of the owner using it for many years. (Houses don't count). The greenest commercial projects I've profiled over the years have been built or are being built by the Bullitt Foundation, the U.S. General Services Administration, a consortium involving the city of Portland, universities or by firms that intend to stay in a space for a long time.
My point is: they don't turn hands. Because of that, there isn't much information about the resale value and market for super green projects in the U.S. created for a specific client. People hypothesize uber-green buildings hold their value better and that there's more demand, but it's hard to prove - without proof. No matter what, this is just one building. But the more sales we see, the more accurately we'll be able to guage the true value of innovative sustainable buildings and whether it's the LEED credential or a building's inherent sustainability that translates as value.
As a sidenote, this is the second time spaces made of cargo containers or using "cargotecture" has been in the news in a week. Earlier this week, the DJC covered a new pilot project Starbucks drive though in Tukwila made of cargo containers. Here's our story and here's the story the AP ran based on our story.
On Nov. 17, the DJC published this article I wrote about Sound Transit's Northgate light rail station. The Northgate station is one of three that will be part of Sound Transit's North Link light rail extension, running from the University District to Northgate Mall. The Northgate station is the only one that it above ground. Because of this, and a number of other factors, it is also the most complex of the three. It is designed by Hewitt.
The article centered on the station's design, and was based off a Seattle Light Rail Review
This is from the story:
Julie Parrett, who is on the review panel and the Design Commission, said this station is unique because the area around it is going through a transformation. Northgate was built for cars and a more suburban lifestyle, but today there is a city-wide effort to make it a place that works for pedestrians, residents and the surrounding community.
Thornton Place, she said, has helped set a standard for new development and the station can reinforce that. She said she doesn’t view the current design as helping shape a new Northgate.
“These are buildings and projects that are going to last for 50 to 100 years and we can’t forget that,” she said. “They do have a civic responsibility and right now, I feel like this building is really turning itself inward and not reaching out and not thinking in a conceptual way what its role (is) as a precedent or precursor in this area."
After publication, Ian Hernandez, a friend of mine, posted this comment on my personal Facebook page:
"Speaking of, great article on the North Link Northgate station the other day! Some of those panel comments crack me up - it's like they think that Thornton Place somehow turned that area into a shining jewel of urban transition, when it's really still just a bunch of crapshacks bordered by a giant movie theater and ugly parking garage."
When I went to the last Northgate station open house, the audience members seemed generally pleased with the station design and some even commended Sound Transit for its work. The Light Rail Review Panel was quite critical, but it looks at the project with the eyes of people who have a responsibility of curating the city's future through projects and urban development.
Here's what's sure: The Northgate area is changing and light rail will be transformative, no matter what it looks like. Given these two things, how much does the station's design really matter? Does it need to serve as a bridge to the future or does it just need to be there? In a perfect world, what would you like to see the station look like?
Also, as a sidenote, this station will have restrooms unlike the ones at Brooklyn or Roosevelt.
Also, if you're really intersted in this topic, go to this open house on Dec. 8 at Aljoya Senior Apartments (a part of Thornton Place). Sound Transit says it has drawn up a "few options that show future urban design and development possibilities for this area south of the mall."
Over the past few decades designers and policymakers have been working to increase the energy efficiency of buildings, and solid progress has been made. Still, today in the United States buildings account for 49 percent of energy use and 46 percent of greenhouse gas emissions. Successfully tackling the dual challenges of rising energy costs and climate change is going to take massive reductions of building energy use.
A conceptual holy grail for energy-efficient building design is a building that generates as much energy as it consumes, a.k.a. a zero net energy building. And that's the goal of a recently completed 10-unit townhome development in Issaquah, WA, known as zHome, touted as the “first multifamily, production, zero-energy, carbon-neutral community in the United States.”
Spearheaded by the City of Issaquah, the zHome project was awarded to David Vandervort Architects in Fall 2007, but subsequently the real estate bust forced the original builder to back out. Howland Homes took over in Summer 2008, and the project broke ground that September. Faced with financing challenges and delays, Howland then partnered with Ichijo, a large Japanese builder known for energy-efficient production homes, and the project finished in September 2011.
zHome was designed to achieve zero net energy use through efficiency measures that reduce consumption by about two-thirds, and photovoltaics (PV) that generate enough electricity to cover the remaining third---approximately 5,000 kWh per year. That requires a hefty amount of PV, and indeed, the south-facing panels that cover the roofs are a prominent feature. During the sunny summer months the PV produce more energy than the buildings need, and the excess is fed back to the grid. If the building operates as expected, that "banked" energy will offset the energy consumed during the dark winter months when PV output is low, the result being zero net energy use on an annual basis.
Energy-efficiency measures incorporated in zHome include ground source heat pumps that provide space heating and domestic hot water, heat recovery ventilation, a tightly sealed and highly insulated envelope (R38 wall, R63 roof, U-0.33 double pane windows), efficient appliances, LED lighting, switched outlets to reduce phantom loads, and a real-time energy monitoring system. (The project is also designed to reduce water consumption by 70 percent.)
So how much did all that extra stuff increase the cost? Asking prices for the units are relatively high for Issaquah: $385k for 799 s.f. 1-bedroom; $530k for 1350 s.f. 2 bedroom; and $625k for 1694 s.f. 3-bedroom. Apparently the free land and significant logistical support provided by the City weren't enough to negate the cost premium. Eventually the upfront investment in efficiency would be offset by savings in the energy (and water) bills, but given current energy prices payback periods are relatively long. Of course, if all the externalized costs of our energy were included it would be a different story, but unfortunately a carbon tax is not happening any time soon.
It remains to be seen if zHome will achieve zero net energy performance in the real world, and success will likely depend to some extent on the energy use habits of the occupants---one thing designers don't have much control over. In any case, whether or not a building can produce enough energy on site to hit net-zero isn't necessarily the be all and end all for sustainable design. Arguably, what's more important is the practice of "efficiency first"---that is, first figure out how to fully minimize the building's energy use, and then worry about how to supply the remaining energy demand.
For example, the Bullitt Foundation's Living Building is targeting zero net energy and incorporates cutting-edge energy-efficient design. But analysis suggests that it could have been even more efficient if it had been built to the European Passive House standard, in which case it would have required less PV, potentially reducing both cost and physical design constraints.
Furthermore, when you look beyond the single building and consider larger systems of buildings and energy production, in some cases powering a building from an offsite energy source may make more sense than struggling to max out on-site generation. And for buildings taller than about six or seven stories, there simply won't be enough solar energy impinging on the site to meet demand, even for a hyper-efficient building.
In conclusion, while the concept of zero net energy buildings may have its limitations, projects like zHome and the Bullitt Foundation building remain hugely important for making progress on energy-efficient design. That's because they challenge designers to (1) work within a highly constrained energy budget, and (2) explore the limits of on-site energy production. And then there's also the potential for the big win as the designs move into the mainstream. Indeed, Ichijo has ambitions to ramp up the zHome concept to high-volume production. It won't be a moment too soon.
