The following post is by Kathleen O'Brien:
New is not always better.
I have to confess that I've been a little put off by local historic preservationists self-righteously declaring that "preservation" equals sustainability and leaving it at that. Yes, yes, I understand that recycling buildings intuitively makes sense, but since sustainability sometimes asks us to think counter-intuitively, I needed more. At a recent Sustainable Cities Roundtable conducted by King County's Green Tools Program, I got what I needed.
Robert Young, PE, LEED AP, is professor of architecture and director of the Historic Preservation Program at the University of Utah, and author of the new Island Press release, "Stewardship of the Built Environment." He was guest speaker at the Roundtable. Young provided some very satisfying arguments for promoting preservation and building reuse as a sustainability strategy. In making his arguments, he gives equal weight to what he terms SEE (or what some of us have called the "three E's"): social, economic, and environmental factors, and defines stewardship of the built environment as "balancing the needs of contemporary society and its impact on the built environment with the ultimate effects on the natural environment."
The Historic Preservationists have been at their best when justifying conservation due to social factors, and Young does speak to this. What I appreciated is that he also addresses environmental and economic factors in an analytical but highly accessible manner. One of the areas he touched on in his talk was the idea of calculating energy recovery as part of understanding the energy performance of preservation vs. new construction. As Young notes in his book, "the argument for measuring embodied energy to justify the retention of a building is (still) met with skepticism." He claims this is largely because embodied energy is considered a "sunk cost" and therefore not part of decisions about future expenses. I think he would also say it's because of our societal preference for the glitter of "new" vs. the practicality of "existing," which may not be part of the accounting equation, but certainly humming in the background.
In his talk, Young used his own home to compare the energy recovery periods required to simply perform an energy upgrade to his home, to abandon the home and build a new one in the suburbs, or to demolish and rebuild in place. When he accounted for the embodied energy in the new buildings (whether in place or in the suburbs), the energy to demolish the existing building, and operating energy required for the remodeled or new building, it became clear that the remodel was the best choice when considering true energy performance. In scenarios provided in his book, energy recovery calculations result in recovery periods that exceed "the expected useful lives of many buildings being constructed today." And this is without calculating in the transportation energy expenses that are likely to accrue when the new building is built in a greenfield out in the suburbs.
In the economic realm, Young compared the job creation resulting from highway, new, and rehab construction. In jobs per million dollars spent, rehab wins again. Although a small part of the construction activity (Young estimated 5%), rehab creates roughly 5 more jobs per million dollars spent than highway construction, and 2 more jobs per million dollars spent on new construction. If I am interpreting Young's figures correctly, just by turning our economic recovery lens on rehab and away from highways and new construction we could potentially create between 6-12% more jobs per million dollars spent on construction. (And we might actually reduce the environmental, social, and economic negative impacts of sprawl -- even if it's "green")!
Young's talk introduced some great food for thought, but I'm so glad to be reading his book. In his concluding chapter, "Putting it All Together," he provides a list of "challenges" for stewards of the built environment, ranging from advocating outcome-based codes (since prescriptive codes are based primarily on new construction practices) to presenting project lessons learned (both positive and negative) to "decision makers and policy shapers who mediate building preservation and reuse policies." Lots to work on.

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?
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."
Because wind energy is such a trendy topic with so many arguments for and against, it's easy to put the turbines that actually generate electricity to the back of your mind. We don't stop to think about how massive these things actually are.
This week, I came across some gorgeous images to illustrate just how gigantic these things can be - and what a huge operation it is to install them.
The project is Puget Sound Energy's third wind power plant, called Lower Snake River Wind Project, near Pomeroy in Garfield County. It recently erected its first wind power turbine. The project should be operating in spring of 2012 with 149 wind turbines, enough to create 343 megawatts or enough energy to power 100,0000 homes. Here is the first turbine:
To install this sucker, huge cranes with booms extending 390 feet in the air set the turbines' lower sections, nacelles and three-blade rotors in place. Many of the nacelles, which contain the turbines' gear boxes and power generators, are being made at a Siemens plant in Kansas. A Siemens factory is Iowa is producing all the turbine blades.
Each rotor is 331 feet in diameter, more than a football field's length. The turbine towers are bolted to concrete foundations taht are up to 8.5 feet thick and weigh more than 600 tons, equal to the weight of more than 100 bull elephants, according to a PSE press release. The turbines weigh more than 240 tons.
The project began in May of 2010. RES America is PSE's lead contractor. To see more photos, click here. It also includes a 15,000-square-foot operations and maintenance building that will have office, warehouse and workshop space. Opp & Seibold from Walla Walla is PSE's general contractor. About 25 permanent employees will occupy the building when it opens this fall.
This week, I toured King Street Station. For those of you who aren't aware, the 1906-built-station is in the midst of a $50 million renovation. The project is absolutely, totally and utterly incredible.
The main thrust of the project is a much needed seismic renovation. Seriously, the tons of steel being put into this project are indescribable. But King Street Station is also a historic building and must be maintained as such. Once the rehabilitation is complete, it will be very sustainable: it's on track to meet LEED platinum, up from a goal of LEED silver. Last year, the project's sustainable efforts were honored by AIA Seattle with a gold level award from the What Makes It Green event. ZGF Architects is the architect. Sellen Construction is general contractor.
Obviously, the most sustainable thing about the project is the fact that it is a historic renovation of an old structure, which retains the embodied energy inherent in the building. But the team went much further. Geothermal wells in the building will likely provide all heating and cooling. The main waiting room will return to its 100-year-old state of being naturally ventilated. Incredible effort has been spent to save, clean and better old building materials. All of these elements will be detailed in a future DJC story.
For now, I'll whet your interest with some photos of the space. As you can tell, I got to tour the inside of the clock tower, which is not part of the current project's phase. However it is really cool. To see more photos of the clock tower or tour, follow my page on Facebook here. And if you haven't voted for this blog yet as best of the web, please do so.

Recently, a story of mine appeared in the DJC called "Smart grid experts say AEC firms should start getting ready." It's about the smart grid, and how it will likely affect many aspects of your life - from the space you live in, to the car you drive to the way you use energy.
Vadari said there's a ton of money heading into this industry and the game changing technology, if it's not already here, isn't far off.
He said the idea of a green building will change from a minimal energy user to an energy producer. As more people get electric cars and pull energy from the grid through buildings, he said a structure that produces extra energy would be ahead of the curve.
“You've got to start thinking holistically because if you just lean more into the grid, you're not helping your carbon footprint,” Vadari said.
Vadari said more thought will be given to combining technologies to save and produce energy, or to achieve multiple goals. For example, he said windows and roofs could become energy-producing solar cells, forcing changes in the market as no one will want traditional windows and roofs anymore.
We're just at the beginning of the smart grid now, with regional demonstration projects funded by the stimulus in motion in all corners of the country. Regionally, Battelle is leading the $178 million Pacific Northwest Smart Grid Demonstration Project. Electric cars, like the Nissan Leaf, are just coming to market and charging stations are just beginning to be installed.
But the potential for the smart grid and its related technologies to change our lives is huge. There's no telling now which direction will move quickest but changes could include market-priced energy with monitors that allow you to control when you purchase energy based on price; electric cars; and homes and buildings that produce energy and feed it back into the grid.
Is there anything -- energy wise -- that you're excited about or looking forward to? Would love to hear your thoughts.
If you've been paying attention, you know 2010 has been a pivotal year for Seattle's waterfront.
In March, the city awarded a contract for seawall work, worth about $18 million, to a multi-disciplinary team led by TetraTech. At the same time, it sped up the schedule to redesign and redevelop its Central Waterfront Project
Wednesday was the RFQ deadline for central waterfront work. A team is expected to be chosen by the end of September. The budget for design work over the first two years is expected to be about $6 million while the estimated budget for planning and design of the entire project is between $50 and $70 million. It got 30 proposals on the urban design/public space side.
Not to mention the process (or sometimes lack thereof) for the replacement on the Alaskan Way Viaduct, which is crucial to how the city's waterfront will be opened up.
Make no mistake about it, these projects combined will totally reshape our downtown. However, in all the hustle and bustle, it can be really hard to imagine just what that end result will be. Or what it is Seattleites want it to be.
If the city proceeds with the deep bore tunnel option, the goal is for the seawall to be done by the time the bored tunnel is complete, currently scheduled for 2016. Construction on the waterfront work could begin this same year.
The seawall may seem like the smallest of the three but how it is designed and managed will be incredibly important to the foundation of the other two projects. One big push is to create places along the waterfront for the public - for you and I - to interact with the water. Places that aren't separated by physical walls but allow us to connect with water, the cultural backbone of our city.
In June, Bob Chandler, city program manager for the viaduct and seawall replacement, said the city is looking for a seawall that supports the waterfront while providing habitat value and creating space for people to interact with the water. “We have an opportunity,” he said. “We need to come up with an approach here that provides protection in a seismic event but that doesn't necessarily mean this is a 35-foot high straight wall. It doesn't mean that at all.”
My question is - how do you envision this?
What should it look like? How do you want to interact with the water, related to the seawall? Once the seawall is complete, what would your optimal redeveloped waterfront look like? Sustainably, what should its function really be?
I recently spent my honeymoon in Greece and Turkey. In each city I visited on the water, there were vibrant spaces located along its edge. I couldn't help wondering what it would take to create the same kind of energy in our city: a bustling mix of tourists and locals that waxes on until the early hours of the morning every day. In Greece and Turkey, the answer is built on history, combined with making these spaces centers of tourism and city life.
These are a lot of questions, often without answer. Part of the point of the design process is to come up with that answer, and there will be a number of opportunities to participate in the formal process. One will be a meeting with teams shortlisted for the central waterfront design work at Benaroya Hall on Sept. 15 - mark your calendar. For now, I'd love to hear your thoughts.
