Here’s a tool to help green roofs grow

The following post is by Oregon BEST:

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.

A green roof sits atop the new Apple store in downtown Portland.

“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.

Frank Ching illustrates new green building guide

Architect Francis D.K. “Frank” Ching, a professor emeritus at the University of Washington, is co-author of Green Building Illustrated, a newly published guide to green building design and construction.

Ian Shapiro, co-owner of Taitem Engineering in Ithaca, N.Y., wrote the text, and Ching was the illustrator.

The book, written for architects, engineers and builders, offers a variety of in-depth approaches to green building design, including a visual presentation of the theory, practices and complexities of sustainable design.

Shapiro emailed the DJC this description from Wiley, the publisher:

From the outside to the inside of a building, (the authors) cover all aspects of sustainability, providing a framework and detailed strategies to design buildings that are substantively green. The book begins with an explanation of why we need to build green, the theories behind it and current rating systems before moving on to a comprehensive discussion of vital topics. These topics include site selection, passive design using building shape, water conservation, ventilation and air quality, heating and cooling, minimum-impact materials, and much more.

Ching recently retired after more than 35 years of teaching. He is the bestselling author of Building Construction Illustrated, among other books on architecture and design, all published by Wiley. His works have been translated into more than 16 languages and are regarded as classics for their renowned graphic presentations.

Shapiro has been a visiting lecturer at Cornell University, Tompkins-Cortland Community College and Syracuse University. He has worked on several LEED building design projects, has led a variety of energy conservation research projects, and is a frequent contributor to ASHRAE Journal and Home Energy magazine.

The guide is available at local bookstores, including Ada’s, Elliott Bay and the University Book Store.

Study makes a case for developing more living buildings

The following post is by Kathleen O’Brien:

In early May, I traveled to Portland to the Cascadia Green Building Council’s annual Living Future Conference. I enjoyed the conference a lot, and especially the very practical financial focus in several of the sessions.


Moving the needle on real estate investment was the topic of a Living Future panel including Jason Twill (Vulcan), David Baker (Earth Economics), Theddi Wright Chappell (Cushman & Wakefield), Stuart Cowan (Autopoiesis). They noted that investment in sustainable real estate seems to be “topping out” in the market at this time — at LEED Platinum. Their hope is to help the market cross that barrier into higher realms of sustainable achievement, such as the Living Building Challenge.
Jason, David, Stuart, and Theddi are coauthors of “Economics of Change: Catalyzing the Investment Shift Towards a Restorative Built Environment.” The research study was funded by Bullitt Foundation, a long time supporter of environmental protection in the Northwest. The point of the study was to “provide evidence of monetized environmental and social benefits…currently not considered in conventional real estate model(s).” The authors hope to provide a defensible rationale for including these public and private benefits into investment models, appraiser methodologies, and supporting policies. This is especially important for U.S. real estate investments where ROI and IRR are the ultimate drivers of most transactions.
The report lays out the ABC’s, if you will, of Ecosystem Goods and Services, the potential Ecosystem Services that Living Buildings might provide, and finally the opportunity to measure, monetize, and value those ecosystem services. The study takes a scholarly approach, a step up from the early days when we in the green building field had to rely more on reason and intuition, since we had little real data to base our assumptions on. (Not that reason and intuition is bad…it’s what got us here, yes?).

"The Economics of Change"

The report also introduces the concept of integrated real estate investment modeling. From this layperson’s view, it seems to build on the conventional model, rather than replace it — an approach that makes a good deal of sense. The methodology they propose will allow many environmental and social benefits currently valued at zero to be seen as economically valuable, and therefore marketable. In the next phase of their work, they plan to produce detailed calculations and case studies of the environmental and social benefits of Living Buildings, test the impact of these values of valuation models or appraisals, and create an open source prototype of the integrated real estate investment marketing tool to “demonstrate how environmental and social benefits can be embedded within a pro forma in an new building development context.”
In addition to taking this tool out to the real estate development communities (appraisers and valuation specialists), they hope to provide a basis for changes in local, state, and federal policy that will acknowledge public benefits of Living Building development and incentivize it.
As Theddi noted, “right now investors are going for the low hanging fruit — energy efficiency — for example. We need to provide sufficient rationale if we want them to go beyond that.”

Hear, hear.

Ellensburg’s energy strategy shows one size does not fit all

The following post is by Kathleen O’Brien:

I had the pleasure this past month of presenting the final product of a two-year process with the City of Ellensburg and its residents for approval. The Energy Efficiency & Conservation Strategy (EE&CS) is one of dozens across the country that were funded through DOE Energy Block Grants. In this case, the grant was administered by the State’s Department of Commerce and locally by the city’s Planning Department.


There are basic elements that are required for every EE&CS, such as developing a vision statement and goals through a public process, and reviewing existing conditions to measure progress. But in looking at the various EE&CS produced around the U.S., it’s clear that each community leaves its very own stamp on the process.
Anyone who’s traveled to Ellensburg for its annual rodeo knows the city has an independent streak, so it is no surprise its EE&CS should be a “little different.” The EE&CS draws on the fact that Ellensburg is one of the few cities of its size that has its own electric utility, and was the first city to create a community-funded renewable energy park, so there was a lot already happening.
In addition, the EE&CS was aligned with a concurrent update of the Land Development Code to make hay of opportunities to use the code to encourage energy efficiency in development and transportation.

Ellensburg Rodeo


Another defining aspect is that the city clearly wanted a planning tool, not a plan. So although there are guidelines and templates for developing plans that address the strategy’s focus areas, and background information from which to draw on, the action plans themselves are left for the city and community to complete over the next planning cycle(s).
Case studies in the EE&CS document are meant to inspire local action, not be imported. The upside of this approach is flexibility, something the city really wanted. The downside (and frankly this is always the danger) is that the EE&CS could end up sitting on a shelf.
When asked by a Council member what would make the difference between successfully implementing the EE&CS tool and its being shelved, I responded: “The difference is you — your leadership will make the difference.”
After a brief pause, the council member said gamely: “I think you’re right!” and his fellow members of the council grinned. The EE&CS was unanimously adopted.
Let’s see what happens next!

King County develops new, green ‘EcoCribz’ video series

Yesterday, King County launched a video series called ‘EcoCribz.’ The series follows one family as they green-remodel their house and aims to teach viewers – you and I – valuable lessons while aiming us towards other green remodeling resources.

The first video, available here, profiles the Bangs family and their Issaquah home. It’s a fun tour that

Image courtesy King County
documents the family’s goal to create a more energy efficient home with better air quality.

Patti Southard, project manager for King County’s GreenTools Program and host of the series, said King County wanted to show people that green home remodeling creates healthy, comfortable spaces that can save money, increase home value and help protect the environment. The county also created helpful remodel tips for renters who are looking at paint and interior options like area rugs and eco-friendly bedding.

The series also illustrates how homeowners can use the county’s Eco-Cool Remodel Tool, another useful resource. Basically, it’s trying to get you to think about your choices before you remodel or build to create a greener space.

Kevin Daniels blogs from New Orleans, DJC blog gets praise, musings and more!

As I mentioned in my past post, I’ve been on a series of vacations over the past couple of weeks. And during my series of nine flights, I had a lot of time to read magazines, catalogues and view countless adds on nameless airport walls. And do you know what I discovered? Green is really, really hip! Before you scoff and say in your head ‘hello Katie, where have you been?’ let me explain:

Over the past two years, even with a recession, sustainability and green promotion has become more than just a tactic. It has become necessary. Flipping through the Crate and Barrel catalogue, furniture

is advertised as being “sustainably harvested and sustainably engineered.” In that same magazine, Calphalon advertises a new recycling program where they promise to responsibly recycle your old cookware, while simultaneously advertising a new green nonstick finish for pots and pans. The message is pretty clear: Crate and Barrel cares about sustainability (hence you should buy their stuff, which I am in no way supportive of or not supportive of, by the way).

At my stay at the Omni Parker Hotel in Boston, it advertised green alternatives like most other hotels nowadays. But unlike many other hotels, it connected those green services to its premium Select Guest program, thereby making sustainability (and not washing your sheets) special.

Starbuck’s has upped the content of recycled fiber in its cups (now 10 percent, not sure when they did that) and touts its eco-consciousness on the side of current cups.

Heck, even Clorox has its Greenworks natural green cleaners label. It just never ceases to amaze me.

Do you agree? Are you constantly amazed?

Anyway, back to the news.Kevin Daniels of Daniels Development is currently in New Orleans where he is repairing homes that are still damaged from Hurricane Katrina. He’s there with the National Trust for Historic Preservation and is blogging about the effort. To read the blog, click here. To learn more about the effort in general, click here. We also wrote about the trip here.

While I was gone, the DJC Green Building Blog was named to two “best of” lists. We were named number 71 on a list of  “100 Innovative Blogs for Architecture Students.” We’re under the category “Eco-friendly architecture.” The list is compiled by a site called that is “dedicated to bringing you the absolute best resources and online educational tools.”

We were also named number 21 (but first under the “Green Construction” category) on a list called “Top 50 Construction Blogs.” This list is compiled by The Construction Paper.

The format of both sites look suspiciously similar though I’m not positive they are related. Hmmm. Either way, they both present a comprehensive list of great blogs, many of which I read on a daily basis to keep informed. It’s a good resource to see viewpoints from around the country and world on construction and architecture.

Incidentally, on one of my many flights, a gentleman I met who owned a construction company in rural Georgia said green building techniques are not used in every project, but are becoming much more common, especially in the major cities and in office projects. He said he’s taking classes on it and suspects they are moving slower than we are on the West Coast, though the south is still moving in that direction.

Seattle’s got a brand new bag … of information!

It’s called the Quick Guide to Green Tenant Improvement series, and is a guide that shows users how to do sustainable commercial improvements in a variety of ten topics. The guides are a product of Seattle’s Department of Planning and Development’s City Green Building team.

The guides are available online here, though I haven’t had time to study them yet. They are

The guides come in many handy flavors
meant to help project managers, owners, interior designers and architects apply sustainable building practices to commercial remodel projects, though a press release says the guide works equally well for interior construction or renovation. Each guide includes an overview of a topic, key benefits and strategies, quick facts, a case study, a checklist, additional resources and potential LEED-CI credits. Helpful? Only you can be the judge.

If you want a hard copy of the series, contact Rebecca Baker at (206) 615-1171.

According to the press release, the guides come in the following fun flavors:

01 Green Lease — A green lease can enhance recruitment, lower healthcare expenses, yield productivity gains and lower operating costs.

02 Connecting with Nature — Interiors with natural elements foster positive connections between people and enhance physical and mental well being.

03 Adaptable Design — “Future-proof” office space by providing for the integration and adaptability of various building systems.

04 Office Equipment — Using energy efficient office equipment reduces energy costs, ambient noise, air-conditioning loads, electromagnetic fields and greenhouse gas emissions while extending equipment life.

05 HVAC: Heating, Ventilation & Air Conditioning — Energy efficient HVAC equipment can reduce energy consumption, greenhouse gas emissions and utility costs while increasing thermal comfort and improving indoor air quality.

06 Lighting — Energy efficient lighting systems can reduce a significant amount of electrical energy costs while enhancing aesthetic design inside and out.

07 Employee Well-Being — The quality of the indoor environment directly affects employee well-being and performance.

08 Healthy Building Materials — A healthy workplace is built, furnished and operated to minimize exposure to sub-stances harmful to human health.

09 Regional Resources — Purchasing locally supports our local economy and reduces transportation costs and emissions.

10 Construction Waste Management — Many construction, demolition and land-clearing waste materials have high value for salvage and reuse.

What’s your water footprint? Calculate it!

If you haven’t guessed by now, I really have fun with calculators. Yes, I know they aren’t always accurate. Yes, I know they often are designed to inflict guilt (and are

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.

If you want to see how much water you use, click here. And if you missed it, click the tag ‘calculator’ below to find out what an ecological footprint is… and how you measure up!

How big is your “ecological footprint” – and what is it anyway?

Sometimes, I get really cool things in my in-box. The Earth Day Network Ecological Footprint Calculator is one of those things.

The calculator, created by the Global Footprint Network and launched today, measures how many planets it would smallcow.jpgtake to sustain your lifestyle. Like most calculators, you go through a series of questions, pick the answers that fit your lifestyle and watch the results come in. But there are two things that set this calculator apart from the pack: the interactivity and the measurement of an ecological footprint.

First the interactivity. Maybe it’s because I grew up in a world of video games but if a tool like this is fun as opposed to bland, I’m a lot more likely to pay attention. And this tool is fun. First, you get to design an avatar (mine had blue spiky hair), and then you get to watch the avatar’s world change as you enter choices that correspond to your life. Fun, no?

Second, and more importantly, the ecological footprint. Most calculators out there measure a person’s carbon footprint. But how much carbon you generate is only part of your impact as a human being. A carbon measurement doesn’t count more esoteric things like how much meat you eat, where you get it and how that affects your impact on the world. 

The ecological footprint, on the other hand, creates a full picture and represents the overall human demand on nature; it compares human consumption with what it takes to regenerate natural resources.

Using this idea, the calculator measures how many planets it would take if the rest of the world lived like you. It’s a really visual way of seeing how much you impact the world… versus seeing a large number that you don’t really understand. For example, even though I recycle everything, almost always carpool, live in an urban environment etc. etc., if all the world lived like me it would apparently take 3.8 planets. And the majority of that (46 percent) is in services. That surprised me. 

bedzed.jpgThe idea of measuring your impact by planets, then decreasing it, is the push behind One Planet Communities and BioRegional, the groups that brought the world BedZed (at left), one of England’s poster children for sustainable living. I wrote about BedZed and One Planet Living in December here in the DJC. According to their numbers, it would take 5.3 planets if the rest of the world lived like the United States does.

There are plans in the works to create One Planet Communities across the world, for more visit

The calculator also offers suggestions after you’re done on what you can do to decrease your result, and lets you change your choices so you can see what exactly affected the final total.  

Though it’s fun, I don’t know how they calculate their numbers and can’t comment on whether the amounts are accurate or not. If you have a favorite calculator that you like better than this one, or can comment on the accuracy of the numbers used, please share your information below. New resources are always appreciated.

More info on the calculator at Plime here.
