Herrera is testing to see whether new soil mixes can remove
more heavy metals and other pollutants from stormwater.
With all the cranes towering overhead in downtown Seattle, it’s easy to forget the important work going on below to manage and protect our water as the region grows.
To keep pace with this growth, Washington State is pioneering the use of new and innovative approaches for stormwater management. As of next year all development projects must use low impact development (LID) techniques or green stormwater infrastructure where feasible. Rain gardens, bioswales, green roofs, and permeable pavement will become the norm rather than the exception.
As the region makes this new investment to protect our water, everyone - regulators, project owners, designers, and the general public included - will want to be confident these technologies are providing the intended benefit.
Herrera Environmental Consultants, Inc. is conducting groundbreaking research to assess and optimize the performance of these systems.
For example, with grant funding from the Washington State Department of Ecology, Herrera is currently implementing two research projects to develop a more effective soil media for use in bioretention systems.
In partnership with Kitsap County, one of these projects has involved numerous pilot scale tests of soil media components and blends to optimize their removal of heavy metals and other harmful pollutants from stormwater.
Herrera has also partnered with the City of Redmond to construct a state-of-the-art research facility for evaluating pollutant removal and plant growth in bioretention systems at full-scale.
Herrera Environmental Consultants, Inc. is an employee-owned engineering and scientific firm focused on restoration, water, and sustainable development. Herrera is committed to working with our clients to develop innovative and sustainable solutions for infrastructure, natural resources, and stormwater projects. Herrera was recently featured as “favorite green collar company” by the Seattle Times.

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.

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.
September and October are always busy months in Seattle's green/sustainable scene. This fall, however, there seems to be a wealth of tours of really interesting projects.
One of the most interesting opportunities is the chance to tour Issaquah's zHome project. Issaquah says zHome is the country's first net zero energy multifamily
Free tours will be held on Saturdays from 10 a.m. to 5 p.m. and on Sundays from 11 a.m. to 5 p.m. until October 30.
- Home Builders Association of Kitsap County Headquarters
Across the water in Bremerton, the Home Builders Association of Kitsap County has improved their headquarters in an effort to create a live demonstration of energy efficiency upgrades for builders and homeowners. The project used six strategies including better air sealing, adding more insulation and adding new efficient lighting to upgrade the space. Tours feature first-hand techniques on saving energy and lowering utility bills. Tours will be held hourly on Sunday, October 23 and Saturday, October 29 from 12 to 4 p.m. Tours are at 5251 Auto Center Way, Bremerton.
- Seattle Design Festival
If you can't wait and want to see something now, I suggest you head on over to the Seattle Design Festival's website here. Though some tours have passed, a
However the one not to miss is Saturday's grand opening of the Brightwater Center. It looks like the official Seattle Design Festival tour is sold out! However, the grand opening celebration is free, open to the public and features plant tours so you can still see the space if you're interested. More info here.
Somehow, I missed posting about a recent story I did on GSA's $72 million headquarters for the Seattle District of the U.S. Army Corps of Engineers. The story appeared in the June 27 edition of the DJC.
From a sustainable viewpoint, it's a fascinating project to consider. It's designed
The project aims to inspire a new era of sustainable workplaces with a goal of being the region's most energy efficient air conditioned building. Models say it will have an energy score of 100, placing it in the top 1 percent of U.S. buildings for energy performance. It may reach LEED platinum, uses geothermal heating and cooling combined with structural piles and is heavily daylit.
But what I think is one of the most interesting elements is GSA knew how much energy it wanted the building to use and asked competing shortlisted teams to demonstrate how they'd get there as part of awarding the project. It went a step further by also requiring the project prove its energy performance during its first year of operation, basically requiring a guarantee from the team.
Generally, anything like this is a big no-no, as I understand it. Under no circumstance, from a legal perspective, should a team guarantee to meet a requirement related to LEED or sustainability. But this is the GSA, the largest
As LEED continues to proliferate and green building fades into the background even further as just a part of good building, do you think this type of performance requirement will become more common? Or is this just a one-time deal?
This week, the Bullitt Foundation's Cascadia Center for Sustainable Design and Construction released a report detailing its energy performance metrics. For all you energy nerds out there, this is a pretty exciting development.
The document outlines how the six-story building will meet net-zero energy. The big
highlight is that it releases the planned EUI of the building, or Energy Use Intensity. An EUI score is expressed in units of thousands of BTUs per square foot of gross floor area. Based on 52,000 square feet of gross floor area, the project should have an EUI of 16. Based on 39,000 square feet treated floor area, a common European measurement, it would have an EUI of 21.
I was recently discussing EUI with members of a ZGF team. They told me the average EUI for an office building in the Pacific Norhtwest is 106.
The report also says the U.S. Department of Energy's Zero Energy Building database currently contains no comparable buildings.
The report includes a pie chart with sections for the center's different energy uses. The largest percentage at 23 percent will feed lights. The next highest amount of energy, at 10 percent are pumps. About 9 percent of the building's energy will feed monitors while 8 percent will feed workstations. Toilets will get .2 percent of the building's energy use.

P.S. The Bullitt Foundation is hiring an administrative and grants assistant. The job description is here.
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.

If you don't have a subscription to the DJC or don't click on our articles as they are locked, you might not know about our free special sections.
Special sections, written by people in a targeted industry for people in the industry, are free to read, meaning even you non-subscribers can access valuable information. Special sections come out about once a month and each section focuses on a different topic. This month's excellent topic is Building Green and I am thoroughly impressed with the breadth of this year's coverage.
In it, you'll find this excellent article by Michelle Rosenberger and Nancy Henderson of ArchEcology called "Watch out for 'greenwashing' by service providers." Among its interesting points, the article examines whether consultants can truly bring a LEED approach to a project without rigorous third party LEED certification. Interesting item to bring up.
There's this great article by Joel Sisolak of the Cascadia Green Building Council called "Two Seattle projects set 'net-zero' water goals," which looks at the region's water infrastructure and two living buildings (The Bertschi School's Science Wing and the Cascadia Center for Sustainable Design and Construction, both covered previously in this blog) that plan to go off the water grid and their challenges in doing so.
Then there's this article by Elizabeth Powers at O'Brien & Co. on whether green parking lots can be (gasp!) green. I'll let you read the article to learn more.
The section also has articles from representatives of Skanska USA Building, Mithun, MulvannyG2, GGLO, Scott Surdyke, Sandra Mallory of the city of Seattle and CollinsWoerman on topics ranging from the city's role in evolving practices to big box stores, student housing and public housing.
So go ahead, check it out and enjoy!
