A unique modeling tool developed at Portland State University with support from Oregon BEST is helping local green roof manufacturer Columbia Green Technologies speed adoption of green roofs to meet legislation aimed at reducing combined sewer overflows during heavy rains and thereby grow the Portland based start-up's national market share.
The new tool is the result of a research project funded by Oregon BEST and led by Graig Spolek, a PSU professor and director of the Green Roof Design and Test Lab. Columbia Green uses the tool when working with civil engineers and architects who need accurate, quantitative data about how much stormwater a green roof in a specific geographical location will both retain and detain.
"This new tool has been very helpful; it's helped us open doors to some of the best engineering and architecture firms in the country," said Elaine Kearney, Technical Director at Columbia Green. "Being able to generate this kind of data bolsters our reputation as being innovative and technologically very forward looking."
Eric Zickler, an associate principal at Aecom, one of largest engineering firms in the world, said his firm uses many different tools to measure performance of their stormwater management infrastructure designs, but the Columbia Green tool stands out.
"Generally the calculators and modeling modules are generic and do not provide a high level of confidence in predicted performance," Zickler said. "The green roof stormwater management tool developed by Columbia Green is specific to green roofs and developed using both theory and empirical data for multiple geographies across varying storm intensities, making it a valuable resource in building our confidence in the stormwater management benefits of green roofs."
The new tool, which can generate data specific to geographic areas and weather patterns, gives Columbia Green a competitive advantage when the company interacts with potential clients.
"The ability to quantify our performance with this degree of accuracy is unique, so it's a significant advantage for us," said Robin Schneider, marketing director at Columbia Green.
This strategic funding exemplifies how Oregon BEST, a state-funded organization that fosters technology-based economic development, helps clean-technology companies collaborate with universities to advance and commercialize products to grow Oregon's green economy.
"It's been very rewarding to see Columbia Green leverage our investment in research and transform that into expanded distribution and sales opportunities," said David Kenney, president and executive director of Oregon BEST.
Green roofs and other green infrastructure approaches are gaining visibility at all levels of government, both in the United States and abroad, as officials try to implement policies to address aging public infrastructure.
Two years ago, Vanessa Keitges, CEO of Columbia Green, was selected to sit on the President's Export Council at the White House.
"We greatly appreciate the Oregon BEST support that allowed us to take advantage of the PSU rain lab and develop a tool that's helping us succeed," Keitges said. "Local cooperation between industries and academia is recognized as a model for innovation to solve global problems."
Oregon BEST is a state agency that nurtures clean technology innovation by transforming new ideas, research, and products into green-collar jobs, greater sustainability, and economic prosperity for Oregon.
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.

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.
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!
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.
For those of you that don't live in the area, Yesler Terrace is a 28-acre publicly subsidized housing community owned by the Seattle Housing Authority. It is in the process of being redeveloped.
District energy systems are common in Europe, especially Denmark. They allow buildings to connect to each other, increasing efficiency and reducing costs by letting several buildings share energy from a main source, such as steam, geothermal, biomass or waste heat.
But they are often cost prohibitive because streets must be torn up for a network of pipes to be built underground.
Steve Moddemeyer, principle of sustainable development at CollinsWoerman, said according to a CollinsWoerman study for SHA, a district water system could cut water use by half for Yesler Terrace and reduce wastewater flows by 70 percent for the same or less cost as a traditional system. Just imagine if you could do that for an entire city!
The fact that Yesler Terrace is considering a water and energy district is really exciting. But what's more interesting is what it says about Seattle. District energy has long been a buzz-term in the city's green community. It seems like we might finally be moving towards getting momentum on new projects.
The city of Seattle hired AEI and Cowi to study district energy opportunities for the city. They are looking at where these systems would be feasible and will identify the top three places. Moddemeyer has seen such interest in district energy and water, he said Yesler Terrace might not be the first project to employ the system. If private developers move forward, he said district systems could be the norm within five years. (Can you even imagine that scenario...?!)
Separately, the city is also working with Trent Berry, a partner with Vancouver, B.C.'s Compass Resource Management. Berry is also providing expertise on district energy systems.
The city of Bothell is also looking at installing a district energy system.
The new projects point in the direction Seattle is heading. But we are also lucky to have Seattle Steam here. Seattle Steam, a district heat provider for 200 downtown buildings, has been around for over 100 years. I'm sure there's a lot of experience they can add to this discussion.
It seems like Seattle has an opportunity here to be a real leader.
Moddemeyer said the biggest obstacle to progress is our faith in the current system. Projects like King County's $1.8 billion Brightwater Treatment Plant put all our water treatment eggs in one basket, betting that water will continue to be treated the way it is in years to come.

I'm not sure about you but things can get pretty slow around here during the holidays. If you're slowing down already, or if you are interested in an exciting winter event to jumpstart your green holiday season, check out the Integrated Project Delivery and Lean Construction program Dec. 13 and 14.
The event Dec. 13 is on IPD and runs from 8 a.m. to 5:30 p.m. The event Dec. 14 is on lean
If you haven't heard of IPD at this point, I'm guessing you live under a rock. It contractually links the owner, architect and contractor with shared financial risk and reward on a project. The text of the program flier words it perfectly: "For some, IPD is just the latest buzzword for collaboration, the latest nuance to evolving project delivery; for others IPD heralds a transformation of the A/E/C industry, leading to new professional roles, collaboration techniques, design and construction process, and final product."
I wrote about "true integrated project delivery" last December in this DJC article on Children's Bellevue, an IPD collaboration between Seattle Children's Hospital, NBBJ, Sellen Construction and Seneca Real Estate Group. It's a fascinating project and a great read.
Sustainably, IPD has the potential to really change the game. Often a problem cited in green development is that teams are brought on too late. But with IPD, all team members are brought on from the very beginning and allowed to flesh problems out on the front end. From a green perspective, this means more efficient or cutting edge systems can be added in holistically and potentially more successfully.
Speakers at the event include AP Hurd of Touchstone, Eric Smith of the University of Washington Capital Projects Office, Jay Halleran of NBBJ, Ken Sanders of Gensler, Scott Redman of Sellen, Ted Sive of Ted Sive Consulting and more. It costs $195 for AIA members and will be worth your time.
However, IPD is intrinsically connected to lean construction principles. The event on Dec. 14 will focus on lean construction basics. Registration for that is $525.
