The Making of the Greenroofs of the World™ Calendar Series

December 1, 2009 at 5:45 pm

An exclusive of Greenroofs.com, we’re now in our  third year of publishing the “Greenroofs of the World™” 12-Month Wall Calendar series.   The 2010 version is now available  and it’s filled with beautiful living roof projects and even more green building events from around the world than the previous last two years.  

The 2010 Greenroofs of the World Front Cover

I thought it might be interesting to some of you to learn about the design process, why and how we choose the highlighted projects – the ideology behind the product, which is our first.   Although I’ve been wanting to write a book (or two) for the last nine or so years, prior to the calendar all our “products” have been intellectual property offerings.   And as you probably know, all of the information on Greenroofs.com is free and  without subscription, following an open source philosophy of information sharing.

I  had  been wanting to do a calendar for years as it was an obvious add on to The Greenroof Projects Database as well as complimentary to our Upcoming Events  section where we list conferences, workshops, presentations, etc., from around the world.   So, voilá!   2008 marked the first year of the Greenroofs of the World™ 12-Month Wall Calendar series.   How do we select our featured projects?    From our website Sponsors, which is the highest level of advertising we offer on Greenroofs.com.   It’s our way to highlight fabulous examples of sustainable roof design and thank these  companies who back us up  by marketing their ecologically friendly products and services with us.   Each chooses their desired month on a first come, first serve basis.   I ask for two of their favorite projects each along with several shots each.   Then the fun starts!   I try and represent different types of greenroofs, sizes, and geographic locations within the U.S. and the world – and of course, the quality of the photo is a huge factor.    This is what is most time consuming!   We include a short description under each photo, and do our best  to list all major designers/manufacturers of record, including the Sponsor.

As you know, greenroofs can be used at any scale, and in the past our smallest featured  vegetated roof came in at 52 sf here in Atlanta, Georgia (2008), and the largest was  a whopping 765,000 sf in Zaragoza, Spain (2009). For 2010, Calendar projects range from 1,000 sf in Manhattan, New York to 113,000 sf in Minneapolis, Minnesota, see below:

April, 2010:  The Target Center in Minneapolis, MN

In addition to displaying eye-catching greenroofs, we also desired an eco friendly product, and I feel like we do create a truly eco-chic calendar!   Our 11″ x 18″ full-color glossy 12-month wall calendars are printed on 50% recycled paper with 25% post consumer waste using soy inks.   We use The Messenger Press  of Carthagena, Ohio where Randy Heitkamp does a great job of printing  excellent quality work – and we recommend him highly.

This year we decided to go global, and you can purchase the 2010 Calendar on Amazon.com as well as from us directly.   But I will say that you’ll save money by ordering through us at only $12.95 each, with free shipping in the contiguous U.S. and Canada (contact us for international shipping rates).   And there are quantity discounts, too.

The 2010 Greenroofs of the World™ 12-Month Wall Calendar will make a great inexpensive  Christmas/Holiday gift or stocking stuffer (well, if you have a really wide stocking!) for all you greenroof aficionados out there.   See  our Press Release here, where you can view each project highlighted in The Greenroof Projects Database.   And find out the details for ordering here.

The (Award-Winning) Green Wall Editor in the News

November 28, 2009 at 10:22 pm

In all the hustle and bustle of editing feature articles,  posting news stories, upcoming events, industry news and project profiles, amid other publisher duties, I sometimes forget to acknowledge the outside accomplishments (from Greenroofs.com) of our contributing editors…   This oversight will be addressed as one of my upcoming New Year’s resolutions, but for now let’s start with George Irwin, our Green Wall Editor:

George Irwin, C.E.O. of Green Living Technologies, discusses the design of an A-frame planter his company makes.

George was recently interviewed for  the “Business of Green” article by Ken Belson titled “The Rooftop Garden Climbs Down a Wall” that appeared in the Energy & Environment section on nytimes.com of November 18 and the New York Times print version on November 19, 2009.   One of his Green Living Technologies‘ living wall products was featured when NYC  architect Brad Zizmor had an edible wall installed on the backyard deck  of his first-floor Manhattan apartment.  

The article really delves into the “Business of Green” – costs are included and Barthelmes Manufacturing Company, the sheet metal fabricator, was also  highlighted as well as Kari Elwell Katzander,  a landscape designer who designed the  3-panel green wall.    Although the author points out that these small greening solutions can be costly, he refers to another of George’s collaborations, the Urban Farming Food Chain green wall project in Los Angeles, and  says:

“Mr. Irwin has shown that edible walls can work on a larger scale. At four locations in the Skid Row area of Los Angeles, there are walls with more than 4,000 plants growing: tomatoes, cucumbers, bell peppers, spinach, leeks, even baby watermelon. At one location, a homeless shelter, residents tend to a six-foot-high, 30-foot-long wall, eating some food they harvest and selling the rest.

The project, urban farming advocates say, is just the start of something larger.”

Make sure to also click on the slide show “Edible Walls of Green” – there are 12 awesome photos of the Zizmor wall, a living wall at the College of Applied Sciences and Technology at Rochester Institute of Technology, and cool manufacturing shots, with just a few below:

Oh yeah, while I’m am it, I should tell you that George Irwin won the Green Roofs for Healthy Cities Award of Excellence in the Green Walls category this year.   Presented on June 5, 2009 at the 7th Annual Greening Rooftops for Sustainable Communities Conference, Awards, and Trade Show at the Hyatt Regency Atlanta hotel in Atlanta, Georgia, he won for his involvement  and contribution to the Urban Farming Food Chain green walls, truly a dedicated community affair of residents, manufacturers, students, professors, activists, and designers.   We were very proud of him, of course, and I should have blogged about this very prestigious accomplishment after the conference, but somehow didn’t.

The Green Roofs for Healthy Cities Award of Excellence for Green Walls

You can read more about this  award from the Green Roofs for Healthy Cities website, and see each of the initial four  green wall sites of the Urban Farming Food Chain in The Greenroof Projects Database:   Skid Row Housing Trust’s ‘The Rainbow’; The Weingart Center Association; Miguel Contreras Learning Complex and the Los Angeles Regional Food Bank Green Wall.

I should also probably mention that because of his work with this project, George has also been on Good Morning America and invited to the White House, too.   I am a forgetful editor, indeed!   George writes about this exciting, worthy,  and humbling experience in his upcoming Green Walls column, which should be up very soon.   Kudos, George!

Roland Appl’s CitiesAlive! Photo Tour

November 22, 2009 at 12:29 am

Last month’s Cities Alive!  Congress  offered many  opportunities to tour many examples of Toronto’s various  green infrastructure  practices, including greenroofs, green walls, and green streets.   Christine and I both shared our experiences on two different “sustainable tours,” and now we  invite you on a visual photo tour of six  locales visited  from a German colleague of ours.   Roland Appl, International Green Roof Association  (IGRA) President   & ZinCo‘s Technical Director,   joined the guided walking Tour A: “Spectacular Green Roofs in Downtown Toronto” and shares these photos with us from October 21, 2009:

Christine’s Reflections on CitiesAlive!

November 13, 2009 at 4:17 am

After Linda’s great coverage of the CitiesAlive! Congress, I’m hard pressed to find anything more to say! However, since I was living in Toronto around the time that green roofs were first launched there, and went on a different Congress tour, I’m glad for the chance to reflect.

The opening ceremony on Monday evening was classy, with a unique green roof touch to it. Once you’d had enough drinks and hors d’oevres in the City Hall foyer, you could go to the roof to see the project. It was fun to stroll through the disorderly chaos of a modular installation, frozen in time until the workers would return next morning.

In fact, the original green roof on Toronto City Hall was my very first introduction to green roofs, as I happened to be there the day of its official launch (Nov. 20, 2000). Funny story, that… I’d just moved to Toronto, fresh out of University and looking for work in the environmental field. On my 2nd day in town, I rang up all the companies I’d (blindly) submitted my resume to, and soon had Steven Peck on the phone. I imagine the City Hall event was a perfect diversion for him to get this young keener off his case. Nine years later…hah!

In any case, it’s impressive to consider that this huge renovation replaces the original modular demonstration boxes. If anything, this suggests that the demonstration was successful and convincing! It certainly also helps that Toronto’s mayor since 2003, David Miller, has introduced an impressive range of environmental policies in his time, including the Toronto green roof strategy of 2008. A lot can happen when open-minded and forward-thinking people step into positions of authority!

The Congress

Tuesday was the only day of talks, which I found a bit hectic. With 4 concurrent tracks going on, and no papers to take home, it was hard to decide which track to go to. Even at the trade show over lunch and coffee, I found this limited  time frame  really challenged the fine balance between catching up with good colleagues/ friends and meeting new ones.

Happily, the congress provided social/ networking opportunities on all three evenings. On Tuesday the Steamwhistle Brewery hosted a BBQ with delicious local brews, as a backdrop to the results of the  CitiesAlive! International Student Design Challenge (Transforming the Face of Buildings). Congratulations to all the faculty-led student teams for their leafy designs! The images below show the first- and second-place winners. First place went to  Cliffside Village, and second place to Compods, both designed by  students from  Ryerson University Architectural Science.  To see the full results of the competition, click  here.

The Tours: GTAA Partners in Project Green

Wednesday was tour day, and I chose to learn more about GTAA Partners in Project Green. The Greater Toronto Airport Authority covers 12,000 ha of industrial and commercial land, including more than 12,500 businesses, and falls under the jurisdiction of 3 municipalities (Mississauga, Toronto and Brampton). Partners in Project Green was founded by Toronto and Region Conservation Authority and GTAA.

I was particularly keen on this tour because the Toronto airport, with its recent mega-redevelopment of Terminal 1, seemed the antithesis of anything “green.” How could such a major development resulting in more air travel be described as a solution for “reducing carbon emissions?” Let’s return to this point later on. The image below shows Toronto Pearson International Airport in the centre, with some features marked to provide some orientation (i.e. Terminal 1, Highway 427 and Etobicoke Creek Stormwater Management Facility). The lands surrounding the airport are part of the GTAA, and therefore also of Partners in Project Green.

Toronto Aerial

The tour started in FESTI (Fire and Emergency Services Training Institute), a LEED silver-certified building which came into operation in 2007. A state-of-the-art facility, FESTI features many technologies to minimize its environmental footprint, such as a solar wall, green roof, recycled building materials and water-saving systems.  This building has a small Sedum mat green roof, around 1,000 sf in size. At the time of planning, the authority lacked references for green roofs and airports, and was therefore conservative due to its uncertainties about animal and bird use. Pity they missed Linda’s paper about Green Roofs and Airports.

FESTI Green Roof

After an extensive tour of FESTI, we went to check out the Etobicoke Creek stormwater management facility. Located under the apron adjacent to Terminal 1, this subterranean facility receives stormwater from an expansive catchment area. It is located underground because surface land is a premium. In order to remain structurally sound underneath taxiing planes, millions of tonnes of concrete were used. Our tour guide, the Head of Environment for GTAA, told us that this project won an award for “the most concrete used in an environmental project.” He wryly added that you can win an award for almost anything these days.

Model of the Etobicoke Creek stormwater management facility

The image  above shows  a model of the Etobicoke Creek stormwater management facility. Note the walkway in the top-right of the image. To give you a sense of how deep and huge this facility is, our guide was monitoring oxygen (and other gases) while we were underground, informing us that “evacuation could not be ruled out.” The model shows how the system works. Stormwater enters the first cell (top of image), then overflows consecutively until the last cell. From the last cell, stormwater passes through two oil separators (the white shapes), which are filled with coalescing plates to trap oil particles, and then released into Etobicoke Creek.

One of four stormwater cells

Welcome to what I affectionately recall to as “the caverns.” The image above shows one cell; and the sub-cells within each cell direct water flow. The image below shows the  walkway, along with a  series of tipping buckets (to the left). When the cells need to be flushed of physical debris, these buckets are rotated to release a deluge of water into each cell.  In this image, note also the trough (almost central in the image) which serves to transfer overflow water from one cell to the next. Many thanks to our tour guides from GTAA for this tour!

Walkway with tipping buckets visible on left

From the airport, our tour continued to the Bayer Headquarters in another corner of the GTAA area. The two Bayer representatives who toured us around the facility showed us everything that made corporate Bayer a great place to work, including an “Outback” walking trail, deluxe fitness facilities, and an 8,500 sf green roof.

The Bayer Green Roof

Installed in October 2007, this Sedum-Allium roof serves purely for “˜green’ image. Inasmuch, the company is not interested in the benefits that green roofs provide and is not doing any performance monitoring. Concurrent with our visit, a 6,500 sf cool roof was being installed on a neighbouring roof.  I was actually a bit taken aback at how confidently our tour guides revealed their limited understanding about green roofs, especially considering our group comprised experts in this field. Where my tireless advocate/ educator side would’ve normally been happy to step up and clarify certain details, the corporate confidence encouraged me rather to let it slide. Let the plants “hibernate.”

Concluding thoughts

As far as the overall congress goes, Toronto certainly deserves applause for hosting Canada’s biggest ever green roof gathering. I was very happy to be there! For me personally, it was a wonderful excuse to travel home from Europe.  However, if I were an international delegate without the added perk of catching up with family and friends on either side of the congress dates, I would not have been pleased with the structure of the congress. Considering that delegates came from as far away as Japan, Australia, and Ecuador, I imagine that many of the congress participants were jet lagged. And  all for one single day of information sharing (for which no materials were provided to take home), one day of tours and a couple social events..?

Regarding the tour that I went on, I was unequivocally glad for the opportunity YYZ_Christine with Pipesto learn more about how the international airport functions; visiting the stormwater “˜caverns’ was a highlight of my life. Seriously.

Overall, and whether or not this was intentional, for me the tour provided a straightforward understanding of how corporate North America uses the word “green.” I learned that “corporate responsibility” looks as good as its intent, which is a bit weak and not fully informed. In both cases the green roofs may as well have been ordered out of a catalogue. They were so small and plain that it was hard to find anything interesting to discuss (which was perfect since nobody knew much about them anyway, neither performance nor function). These green roofs were simply novel additions to the corporate environmental portfolio, in which appearance has more value over performance.

Recalling my original curiosity, this may also explain how the new Terminal 1 is attributed to reducing emissions and stormwater runoff. Our guide from GTAA explained that the larger apron at Terminal 1 means that planes now queue and taxi less, thereby reducing the projected emissions compared to when it was smaller.

This logic is reminiscent of the typical emissions reduction reasonings associated with Kyoto, isn’t it, namely comparative extrapolation rather than baseline reduction strategies. With regards to stormwater, while we were impressed to see how this issue is managed I didn’t really get a clear answer of stormwater is reduced (and “reduced” is the term used, several times). Further to emissions, stormwater and  the LEED-certified building, additional green initiatives include the Airport’s cogeneration facility, xeriscaping, and reuse of 99% recycled material from the old terminal (by weight).  Considering the scale of the Airport lands, such commitments play a big role to its ecological impacts (however misleading the corporate statements are).

The Mexican Fiesta which closed the Congress at the Toronto Botanical Gardens was fun, with a live mariachi band and free Coronas for all. Terry McGlade did a great job of showing people the green roofs, and it was a great way to close off the Congress. Linda did a great job of summarizing the Fiesta, with wonderful photos, so if you haven’t read her blog post please do check it out!
