Each week you can expect to learn What’s New here on Greenroofs.com through our “This Week in Review” video.  Here’s the transcript from October 28th and 21st, 2011 from our daughter, Anjuli – click on the photo below to see the video, or here.  Enjoy!

- Hello, I’m Anjuli Velazquez and welcome to This Week in Review for October 28th, 2011 as well as last week, October 21st on GreenroofsTV.

- Projects of the Week

-  Our project of the week is the PECO Main Office Building built in 2008 in Philadelphia, Pennsylvania. The rooftop garden, on the top of an eight-story section of the building, holds growing media up to 8 inches thick, and the vegetative covering will reduce rainwater runoff by up to 70 percent and provide better insulation. With an anticipated investment of $15.3 million, the initiative also includes the opening of PECO’s first green building in West Chester, replacement of the landmark Crown Lights messaging system atop the company’s Center City headquarters, energy efficiency upgrades at many of the company’s offices and service centers across the region to comply with LEED certification, as well as community and customer support for energy efficiency and environmental benefits. Mayor Michael Nutter has recognized the roof as a step forward in his quest to make Philadelphia the greenest city in America. In the effort to encourage a critical mass of enlightened Philadelphians to support the development of urban roof top landscapes, the PECO green roof is proving to be a key player. Roofmeadow and the Philadelphia Horticultural Society closely track the native plants to identify those that are best able to endure the harsh conditions of a windy, riverside rooftop.

- Our project of the week last week was the Ngee Ann Polytechnic’s Vertical Extensive Green Wall Testing Facility built in 2009 in Singapore. The Landscape Design and Horticulture programme from the School of Life Sciences and Chemical Technology at the college embarked to develop simpler green walls for high rise buildings where 90% of residences are dwellers. Then they evaluated shallow rooted plant species for their growth habit, disease susceptibility, nutrient deficiencies and maintenance requirements. The 2-year research on sustainable plant species for the green wall involved 40 students from the Landscape Design and Horticulture programme and the outcome was a 12m x 2.5m vertical extensive green system uniquely designed for the climate in Singapore.

“What’s New”

- Industry News Update

-The next round of ecoroof incentives is now open & the City of Portland is again offering FREE technical workshops.

- Green Roofs for Healthy Cities’ Awards of Excellence Winners Announced – congratulations to all the great projects and winners, in particular to one of our Contributing Editors, Patrick Carey of hadj Design as the Green Roof Designer, who won in the Green Roof Extensive Residential category for the Hood Canal Project, a private residence in Quilcene, WA.  The greenroof on this coastal residence is a perfect example of a small-scale project with an even smaller development impact.

- The EPA asked ASLA to collect case studies on projects that successfully and sustainably manage stormwater. ASLA members responded with 479 case studies from 43 states, the District of Columbia, and Canada – by the way, one of the projects where Linda was the greenroof design consultant is included – Rock Mill Park in Alpharetta, Georgia.

- The NY State Department of Environmental Conservation and the New York City Department of Environmental Protection reached a draft agreement to reduce combined sewer overflows into area water bodies. The agreement modifies New York City’s approach to improving harbor water quality, under which the city will invest an estimated $187 million in green infrastructure projects by 2015, part of a planned $2.4 billion public and private investment over the next 20 years.

- “In the News”

- Mitsubishi Heavy Industries announces that the “Tamachi Building Co. Invites Kindergarten Children to Potato Dig At Company’s Rooftop Garden.” They are offering a fun learning opportunity about the environment as a corporate social responsibility activity. They say, “Within the rooftop garden, a 21.5 square meter vegetable garden has been used for potato cultivation. Sweet potato was selected for planting because during the summer season it offers a high green coverage ratio, thereby providing excellent heat insulation; also, sweet potatoes offer good opportunities for children to dig and taste. The remainder of the garden is being utilized primarily for planting grass, flowers and evergreens.”

-  AnnMarie Costella of the Queens Chronicle, reports on “Queens gets a bit cooler with another green roof.” She says the “Jamaica Wastewater Treatment Plant is [the] latest location [to] be outfitted.” A variety of large and small flowering plants have been planted on this 6,000 square foot building, which will be able to absorb up to 13,000 gallons of rainwater and lessen the amount that gets dumped into the sewer system that leads to the Jamaica Bay. This green roof is part of the NYC Green Infrastructure Plan, which calls for $2.4 billion worth of green projects over the next 20 years in order to reduce combined sewer overflows and increase buildings’ absorption of ultraviolet light. Green roofs also improve insulation, interior cooling and energy efficiency.

Did we miss something?  We’d love to hear from you!

~ Linda V.

Last week I told you about our Keynote Speakers for the Greenroofs & Walls of the World™ Virtual Summit 2011 - Andrew Grant, Charlie Miller, Ed Snodgrass and Ralph Velasquez –  awesome thinkers, designers, trend setters, eco-luminaries all of them!  And among others, we have French botanist and modern green wall pioneer Patrick Blanc, whom I’m interviewing this afternoon in Chicago…

See the GGW Virtual Summit Speakers page and Agenda to learn all about each presenter and their presentations or the panel sessions.

Speaking of our panel sessions, we have seven very distinct, innovative, and important collaborations that you are sure to enjoy and learn from personal experiences of movers and shakers in their respective fields from international non-profit, private and university level to U.S state, city, and borough level to professional association, private enterprise, and corporate experiences.

Click on the photos or titles to learn more about each scheduled time slot on the Agenda and each individual - they all have live Question & Answer sessions afterwards, so don’t miss them to pick their brains on how they are succeeding in greening our roofs and walls:

“Biodiversity and Greenroofs” above left to right: Christine Thuring (Moderator), Nathalie Baumann, Dusty Gedge, and Gary Grant discuss original research and unique experiences, from field work upwards to bigger picture perspectives, as well as corresponding experiences with legislation on urban nature conservation.

Christine is moderating the panel on “Biodiversity and Green Roofs” where she also speaks about her research on plant community development and ecological processes on extensive green roofs with time.  Nathalie speaks about “Green Roofs / Natural Roofs = Biodiverse Habitats and Ecological Compensation in Urban Space: 15 Years of Experience in Switzerland.”  Dusty speaks about “Designing and Working for Biodiversity on Green Roofs for Over 10 Years.”  And Gary speaks about “My First Biodiverse Green Roof in 1992, Considerations for Planning and Design and Some Thoughts on the Future.”

“Greenroofs & Walls for Educational & Social Equity in the Bronx” above left to right: Robert Bieder (Moderator), Jon Beuttler, Jess Dannhauser, Bronx Borough President Ruben Diaz Jr., Javier Lopez, New York State Senator Gustavo Rivera, and Steve Ritz.  Fueled by a passionate and committed Bronx Borough President, Ruben Diaz Jr., it is common knowledge that the Bronx is leading NYC in embracing green technologies and the green economy. To wit, the policies and educational initiatives underway in and of the Bronx are making dramatic strides in the quality of life and opportunities for all residents with concentric benefits and ripples felt citywide, statewide and nationally.

This panel featuring: a State Senator, noted business leader, NYC project manager, health care manager, social service providers and a dedicated educator speaks to triple bottom line benefits, impacts and the uses of green roofs, green walls, and urban agriculture as highly replicable, critical components to creating and leveraging social equity and economic and educational opportunities in challenging times.

“The Portland Ecoroof Program: A Cross-section of the Green Roof Movement in Portland, Oregon” above left to right: Tom Liptan, Matt Burlin, Amy Chomowicz, Casey Cunningham, and Alice Meyers.  The Portland Ecoroof Program started in 1996 when a city employee constructed an experimental ecoroof on his garage.  From this small start, the program has grown and as of July 2011 there are over 420 green roofs of varying sizes, on all types of buildings, from multi-story apartment complexes and commercial buildings to humble sheds, kiosks, and garages.  These green roofs cover nearly 30 acres of Portland rooftops (extensive and intensive roofs).

The Portland Ecoroof Program consists of technical support, incentives, education, policies, and research.  The program is incentive-based rather than regulatory, and the city’s policies reflect this approach.  This presentation provides an overview of how these program elements work with the private sector and general public to sustain the green roof movement in Portland.

“Vertical Agriculture: A Global Movement Starts Locally, from Walls & Roofs to Table” above  left to right: George Irwin (Moderator), U.S. Congressman Tom Reed, and Tom Ferraro.  Urban agriculture is on the rise globally – up the walls and on rooftops.  Fresh, local crops benefit the entire community for many reasons.

U.S. Congressman Tom Reed from the 29th district of New York, Tom Ferraro, CEO of Foodlink – a national network of 200 food banks – and George Irwin, CEO of Green Living Technologies International (GLTi), provide interactive conversation and commentary concerning the impact of education, economics and opportunity around local food production with green walls and roofs.  Rochester-based GLTi started in New York City and has since grown nationally and internationally through education and collaborative hands-on projects with local youth, the underprivileged and disadvantaged in New York and Los Angeles and with business partnerships in Santiago, Dubai, and beyond to include their Food Factory and more.

“Wind. Water. Heat. Grow. Greenroofs.” above left to right: Dr. Bill Retzlaff, David Aponte, Kevin Songer, and Joe Webb.  Greenroofs are impacted by wind, water and heat on an unrelenting basis.  Through wind trials and real hurricane survival stories in Houston, TX, Jacksonville, FL, Edwardsville, IL, and Puerto Rico, we have met those challenges and will discuss various projects’ responses and successes to Hurricanes Ike and (any others?).  Drought, hot winds, and unseasonable 100° days can also quickly desiccate or kill greenroof plants.

Dr. Bill Retzlaff moderates discussing wind studies and plant trials for greenroofs at SIUE. Joe Webb talks about his project which endured 110 to 120 mph winds and 11” of rain in 24 hours and shares water mapping and Living Building Challenge Water requirements.  Kevin Songer talks about the Outdoor Turbine Hurricane Simulator at the University of Florida, water conservation through ‘nature-based irrigation design,’ and the importance of biodiversity.  David Aponte speaks to his experience of engineering and designing greenroofs with the correct growing media and plants in hurricane-prone, sub-tropical Puerto Rico.

“Greenroofs: Wind & Fire” Panel above  left to right: Kelly Luckett, Mike Ennis, and Jim Kirby.  No longer can the green roof be deleted from a project due to failure to comply with the fire code.  After three years in the making from members of Single Ply Roofing Industry in cooperation with Green Roofs for Healthy Cities (GRHC), we now have a green roof design guide for minimizing the risk of fire on green roofs.  The securing of a place in mainstream construction through the International Code Council (ICC) has resulted in a milestone for the North American green roof movement. Fire concerns are only half of the code story as the wind design guide is still progressing through the ANSI process – we must overcome both the wind and the fire obstacle.

Kelly Luckett, President of Green Roof Blocks, moderates and shares his experiences representing GRHC with the consensus based ANSI/SPRI VF-1 and RP-14 standards.  Jim Kirby, NRCA’s AED, Technical Communications, provides NRCA commentary about building codes, vegetative roofs and RP-14.  Mike Ennis, Technical Director for SPRI, speaks to SPRI’s leadership leadership in the development of fire and wind standards and experience in the building code arena.

And, because the panel sessions weren’t stirring enough, we’ve ended with the “Green Roofs Without the Hype” Panel above left to right: Patrick Carey, Dr. Robert Berghage, Charlie Miller, and Ed Snodgrass.  Here are four people with the knowledge to speak frankly about the current state of affairs in green roofing.  This panel focuses on the designation and evaluation of expertise, appropriate background and training, roadblocks to research and education, design origination and control, chain of custody issues, installation, and the residential market.

Patrick Carey, hadj design principal, member of the Northwest EcoBuilding Guild, greenroof designer and Green Roofs for Healthy Cities trainer extraordinaire – and Architecture Editor here on Greenroofs.com – is featured in the July 27, 2011 KING5.com Evening Magazine video “Go Green with Greenroofs.”  Click below:

Host Jim Dever describes how a green revolution is sprouting up, so to speak!

Patrick is interviewed extensively with Seattle City Hall in the background and on location at several area homes, including the Mazurek Art Studio and Jon Alexander’s Garage.

I was lucky to have visited them all and more along with Patrick Carey in August 2004 – read about it in my previous column (and inspiration for this blog), “Sky Gardens ~ Travels in Landscape Architecture” here.

“I think that green roofs are the greenest thing you can do in construction except not build at all!”  ~ Patrick Carey

Way to go, Patrick!

By the way, Patrick Carey will be leading one of our panels sessions at our upcoming Greenroofs & Walls of the World™ Virtual Summit 2011 on August 23 and 24, 2011:  Join him along with Dr. Robert Berghage, Charlie Miller and Ed Snodgrass as they examine “Greenroofs Without the Hype.”

Knowing those four, it should be pretty interesting!  Happy Greening,

~ Linda V.

The Pacific Northwest in general is known for eco-friendly, sustainable building policies, high-performance green architecture, and local innovative building designs.  In fact, Seattle holds the distinct position of being the first U.S. city government committed to Silver LEED™ facilities, adopting its Sustainable Building Policy requiring new city buildings over 5,000 sf to obtain the U.S. Green Building Council’s certification rating in 2000.  But the Seattle area also distinguishes itself in that it has an unusually high number of residential greenroof applications.

Our GPW through today is the lovely 280 sf “Private Seattle Green Roof Garage,” built in 2003 by architect Rob Harrison and his wife, Frith Barbat.  Located in a geographically diverse southeast Seattle neighborhood, the area is filled with parklands, lakefront, wooded hills, and quiet residential streets and boulevards.  Aside from the living roof, construction methods were eco-conscious from the beginning as the homowners capitalized on the property’s existing carport foundation and built the garage mostly with materials salvaged from the previous deck.  It’s really not surprising, since Rob Harrison, AIA, is a Certified Passive House™ Consultant and principal of HARRISON architects. 

The Seattle, Washington firm has been in business since 1984, with the last 18 years devoted to sustainable design.  HARRISON architects’ work is based in “lyrical sustainable design”: conserving energy and resources, using healthier materials and finishes, reducing long-term costs, and making poetic places.  By working with consultants, contractors and suppliers who share their values, the experience results in a convivial, collaborative design and construction process.  And when you’re the client/architect, and it’s easy to be creative in this environment.

“Since it was our own house (rather than a client’s!), we thought it would be a great opportunity to experiment with a less expensive residential alternative to $15/sf proprietary (and warrantied) green roof systems used on commercial projects, and so promote the use of green roofs in residential applications.” ~ Rob Harrison

And since Rob was a member of the local chapter of the Northwest EcoBuilding Guild, he had plenty of local expertise and volunteers for help.  The Northwest EcoBuilding Guild is an alliance of builders, designers, suppliers, homeowners, and partners concerned with ecological building in the Pacific Northwest.  Their mission is to provide leadership in education to transform the built environment and build a sustainable society.  In those years, hadj design directed the greenroofing efforts for the Guild, and the firm’s principal, Patrick Carey (also our Architecture Editor), was one of the consultants and volunteers on this project, as seen below in the bucket brigade system used to haul the growing media up to the roof.

Originally, Rob designed the space to call his own for a “manly” workshop (the garage is featured on the cover of the book ManSpace: A Primal Guide to Marking Your Territory by Sam Martin, about “dens, caves, lairs, hangouts, hideaways, workshops, studios, drinking sheds and man houses”).  The one-car garage housed space for tools, one bicycle, two vintage motorcycles and their Mini Cooper.

But things have changed – at present, the garage now holds just one motorcycle (a new gas-efficient model with a catalytic converter) and the family’s six bicycles.  They sold the car seven months ago, and have been giving the car-free life a try – so far, so good!

Originally planted with Eco-Turf (a mixture of baby blue eyes, red clover, yarrow, and fescues) and a variety of drought tolerant sedums, they’ve also added strawberries, nasturtiums and poppies to the greenroof.

Venturing onto YouTube this past February, Rob came across the above advertisement for Pepsi’s new humanitarian/environmental effort, the Pepsi Refresh Project, and was surprised to see his own green-roofed garage!  He explains that a couple years ago fashion/rock star photographer Karen Moskovitz came over with a young model family to shoot some stock “lifestyle” photos and video using his garage as the backdrop.  He’s quick to point out that it’s not him watering the roof!

“We might do that if we’ve planted new plants up there and need to get them started, but otherwise, not,” Rob says.  Actually, maintenance has been really minimal – they only watered the first year during establishment and have only spent about one hour’s worth total weeding and the occasional introduction of new plants during the first three years.  He adds, “It’s a bit odd to be shilling Pepsi, even if very indirectly, but I do like the idea that we are clearly living in some one’s idea of a better future!”

By the way, the Pepsi Refresh Project is looking for people, businesses, and non-profits with ideas that will have a positive impact in their communities, and is giving millions of dollars in grants in the categories of Health, Arts & Culture, Food & Shelter, The Planet, Neighborhoods, and Education.

Any lessons learned with a greenroof so close to home that you can see daily?  In the more recent photos that Rob sent me, see above and below, it’s obvious the roof has seceded to mostly grasses, so I asked him if is it still that way – Yes.

Rob says now that the roof is seven years old, in retrospect he would not have introduced any grasses on the roof at all, as the area planted in Eco-Turf has spread over the entire roof and overtaken the sedums, which are still there, but are hard to see.  But he muses, ”The wavy grass does have its own attractions, especially in the dry summer here, where it reminds me of the Palouse in eastern Washington.”

Does he plan to keep it as it has naturalized or does he have other designs?  Rob’s response: 

“I’m of two minds on the secession of the roof to mostly grasses.  On the one hand I like the look of the grass, and the way the motion of the grass in the wind animates the building, and it’s tempting to let the roof do its own thing and see what develops naturally.  On the other hand, grass forms a dense mat of roots that is surprisingly impermeable.  We haven’t made a big decision to replant the whole roof yet, but we’ve been pulling out clumps of grass here and there, and planting more sedums as we acquire them from friends and neighbors.”

This beautiful private Seattle vegetated roof is one example of sustainability on a smaller scale in a city full of greening efforts.  It has been featured in many publications and tours, both public and private. The photo above resulted from an AIA Seattle seminar on greenroofs held at the architect’s home in 2006, in conjunction with folks from Bohlin Cywinski Jackson.

Visible from the alleyway behind it and, more importantly, from the home’s kitchen window, the Harrison/Barbat family agrees their Seattle garage greenroof is a pleasure to behold every day – in all seasons and all forms.

Before the second day of Ecoroof Portland’s Vendor Fair and program sessions, Tom Liptan co-led an ecoroof tour starting at 8:30 a.m.  Along with Jason King of TERRA.fluxus, on March 13 the group was comfortably and efficiently transported by ecoShuttle around northeast Portland to see a variety of roofs, below.

The five sites visited on Saturday morning were the Metro Regional Headquarters Ecoroof and Yakuza Restaurant (above), K-4 Condominiums (left), and the O’Brien and Omey residences (below).

I’m sorry to say we just couldn’t make ourselves get up early enough to join in!  But our trusty friends Casey Cunningham at the City of Portland Bureau of Environmental Services and Jason shared these photos with us (I hope to add/update these profiles soon to The Greenroof & Greenwall Projects Database) – by the way, Jason King is a very talented landscape architect here and has been involved with many ecoroof projects, including the Multnomah County Multnomah Building, top photo above.

After the 10:30 Intro to Portland Ecoroof session, Commissioner Dan Saltzman welcomed everyone and spoke about the City’s vision for a sustainable future and some of their ongoing projects.  Then I was introduced as the keynote speaker, sharing my presentation “Hot Trends in Greenroof & Greenwall Design.”  A compilation of my favorites from the past three years of Haven Kiers, our Design Editor, and my Top 10 List of Hot Design Trends in Greenroof Design, I also added some outstanding projects that will make our Top 10 for 2010 (under construction), including this one below, the $90 million Oregon Sustainability Center, designed by Portland firms SERA Architects and GBD Architects:

Saturday’s first afternoon session was all about case studies – small and large, public and private.  Kevin Falkerson, AIA, and Kerrie Lee Cole, GRP, of SYMBIOS shared their experience of design-based solutions with the Salmon Creek School living roof, from concept through construction and follow-up.  The LEED Platinum Sonoma County, California environmental center has many eco-friendly features, offering the students of this K-8 grade school numerous opportunities for place-based learning – about the ecology of the natural site and the greenroof itself.

The semi-intensive roof sports a diverse palette of non-native and native sedums and succulents, accented with beautiful detail plantings including boulders and rocks.  See a photo gallery here.

Next up was the energetic Walt Quade, a general contractor with Cully Construction Co. (and Green Home Oregon), who built his own energy-conscious, partially underground home with a custom-designed 1,490 sf greenroof in north Portland.  He also started from research to conception through several design options, before deciding on the one that would best suit his family’s needs and desires.  Walt not only described the construction process step-by-step, he also provided insights on lessons learned.  His message was clear:  ecoroofs do not need to be a high cost item if you are knowledgeable about products, and they are not that difficult to execute – but you do need to know your limitations and hire professionals when necessary.  See his photo gallery here.

Karl Schultz from the Port of Portland followed with the new sustainable headquarters facility for the Port of Portland at PDX, Portland International Airport.  Situated in front of the terminal which is connected to the parking garage, the 10-floor LEED Gold-designed facility has extensive daylighting, high performance glazing, radiant heating and cooling ceiling, reflective membrane, and a Living Machine – an organic wastewater treatment system that treats wastewater onsite to be used in the building for non-potable uses.

The structure also features an intensive built in place greenroof on the 8th floor and the larger 10,000 sf LiveRoof modular greenroof on top of the 9th floor on the north side installed for rainwater treatment  – both incorporate “adaptive plant Micromist irrigation.”

The final session was the very interesting, informal, and lively ”The Ecoroof Doctors are IN” panel with Tom Liptan, Ed Snodgrass, Patrick Carey, Dave Elkin, and Alice Meyers from the BES Ecoroof Incentive Program.  They offered advice and fielded many questions from architects, homeowners, and designers about a ton of subjects – from which are the best plants to benefits of modular vs. built in place systems to construction details.

Earlier this year, March was declared “Ecoroof Portland” month by Mayor Adams, and the learning and fun didn’t stop with Ecoroof Portland 2010 - here are a few more opportunities to learn what they’re all about from sponsors the Portland Audubon Society, Urban Greenspaces Institute, and the City of Portland (check for space availability):

South Waterfront Ecoroof Tour, March 27th
Green Roofs and Living Walls for Wildlife, March 30th – with one of our perennial favorites, Brit Dusty Gedge of Livingroofs.org 
Downtown Ecoroof Tour, March 31st

We left Portland with a greater understanding of how City employees, from the Mayor to City Commissioners to everyone at BES, view their work.  I felt that the employee buy-in for eco-friendly stormwater management options for a cleaner and greener Portland is just amazing!  It was evident from everyone we met how much they loved their jobs and how strongly they felt that ecoroofs were a real solution.  They really impressed me with their friendliness, professionalism, and dedication – thanks for inviting me!

Oregon is a land of widely different people, places, and ecosystems, and the beautiful City of Roses is always a pleasure to visit.  The City of Portland serves as a shining example to the rest of the U.S. on how municipal government can really work effectively for and with their people to promote healthy, sustainable development.  Ecoroof Portland is a win-win event for everyone here – the citizens, the City employees, and as a result from all the support and financial incentives, the local environment as well.  Stay in touch by visiting the City’s BES website.

Since the 1990s, Portland, Oregon, has worked hard to earn its reputation as a sustainable building pioneer.  Very socially conscious, it’s also a very young city in terms of energy and spirit.  As the host of Ecoroof Portland 2010, the City of Portland’s Bureau of Environmental Services (BES) does a great service to its citizens with this free yearly event with information and technical assistance about ecoroofs – other sponsors included ReDirect Guide, EcoMetro, KXL radio, KINK radio, Portland Business Journal, Left Bank Annex, and ecoShuttle.

A large number of BES staff was on hand to assist, but Matt ran the show.  Matt Burlin is the Outreach Coordinator, Sustainable Stormwater Management, City of Portland Environmental Services, and did an excellent job of organizing and coordinating everything!  Held at the Left Bank Annex close to the Rose Quarter, Ecoroof Portland was easily accessible by public transportation, and in fact, the city encouraged folks to do just that.  The industrial urban space venue was chock full of environmentally friendly features including great daylighting, recycling bins everywhere, and water conservation features in the restrooms.

The program provided options for all levels of sophistication – beginner, professional, researcher, and those who were ready to put an ecoroof on their own house or commercial structure.  Friday started out at a very civil 10:30, with ”An Introduction to Ecoroofs in Portland” given by Matt and Amy Chomowicz (also offered on Saturday morning).  Attendees heard about general ecoroof information – how they work, why they’re important, and what resources are available in Portland to help you get started on your own project to gain skills and experience in the industry.

 
The Vendor Fair was open at 10:00, and I was surprised to see how full both the intro session and exhibitor area was for a Friday morning.  We skipped the intro and perused the trade show on the main floor, mingling with old friends and meeting new ones.

These regional expos are so important for a variety of reasons, and it also gives us an opportunity to meet with local reps of some of our advertisers, too, and learn about business in their neck of the woods – we connected with “new” folks from Tremco, Tournesol Siteworks, American Hydrotech, Xero Flor America, GreenGrid, ILD, and Etera Green Roof Plants (Northwest Horticulture), below.

I was pleased that there was such a high number of professional firms exhibiting among the manufacturers and suppliers, for example landscape architects Lando & Associates Landscape Architecture(who have worked on many ecoroofs here including The Metro Headquarters Greenroof) and Walker Macy (who worked on the Platinum LEED OHSU CHH building, among others).  Architects, consultants, contractors, structural engineers, and researchers also had booths.

In addition to product and service vendors, non-profit organizations and community organizations were also here including the Green Roofs for Healthy Cities booth, which was manned by Patrick Carey, a trainer for all of the courses needed to get your GRP designation – the 101, 201, 301 and 401.

And it was great to see Ecoroofs Everywhere and meet Greg Haines, above left, after all these years (who used to work at BES, seen with Matt, right).  Greg has been installing ecoroofs in Portland since 2002 when he co-founded Ecoroofs Everywhere as a non-profit organization (since 2007 it has been a for-profit partnership).  Of course, the City of Portland had booths to answer questions about their Ecoroof Grant Program (they gave out beautiful posters) and WorkingGreenPortland.com, a website and tool to educate and motivate people about site specific stormwater management options, and city grants and incentives for each.

At noon, Environmental Services Director Dean Marriott welcomed everyone, gave us a quick update on the Ecoroof Grant program and introduced the keynote speaker, Ed Snodgrass.  Ed, in his usual laid back and affable way, presented “Ecosystem Services: How Ecoroofs Contribute to Sustainable Cities” sharing his thoughts on how greenroofs add benefits to our highly sealed urban areas by mimicking natural processes within the bigger picture.  He showed multiple examples of how the natural technologies of plants and soil protect the environment, economy, and equity in cities through connecting living roofs, rain gardens, porous paving/vegetated parking lots and other systems, while providing stormwater management, energy reduction, cooling properties, treatment of graywater and sewage, wildlife habitat and more – for example the corporate campus of Mercedes-Benz, below, a model of sustainability.

Next came current research and monitoring efforts specific to the area. Portland State University (PSU) graduate student Debbie Beck gave a presentation on “Greenroof Soil and Water Quality – Changes in Runoff Water Quality When Biochar is Mixed into a Greenroof Soil.”  Growing media needs to be designed to ensure low concentrations of nutrients in stormwater runoff; biochar is a soil amendment made from the pyrolysis of waste products, ranging from biomass to tires in a carbon-net-negative process.  It was evaluated for its ability to retain nutrients in greenroof soils, and Debbie also presented findings on its cleansing properties.

Tim Kurtz, PE, from the City of Portland BES talked about ”Stormwater Monitoring of Three Ecoroofs in Portland, Oregon” explaining that although ecoroofs have become a primary option for reducing roof runoff into sewers and streams, at present they’re all treated the same, regardless of growing media depth or composition.  Data was presented from the Hamilton Apartments, the Multnomah County Multnomah Building, and the Portland Building, above, to determine which greenroof design and maintenance variables are most important to maximize stormwater retention.

 And featured speaker Dr. David Sailor from PSU presented “Energy Performance of Ecoroofs – the Role of the Roof in Affecting Building Energy and the Urban Atmospheric Environment” – enlightening us how energy analysis of ecoroof performance requires sophisticated techniques and that complex energy balances on vegetative roofs vary from time of day and season to season.  Dr. Sailor concluded with his initial results of studies involving both greenroofs and photovoltaics, with a focus on potential system interactions and synergies.  His findings clearly demonstrate the effectiveness of the two technologies working together – the plants fare better with some shading from the harsh sun and the panels perform better from a cooler rooftop.

“Portland’s Shift to a Sustainable Future: The Role of Ecoroofs” took over the late Friday afternoon session with an interactive panel featuring Dan Vizzini of City of Portland Environmental Services, Tom Puttman of David Evans and Associates, and Tom Liptan, ASLA, Ecoroof Technical Program Manager with BES.  Fourteen years after ecoroof guru Liptan installed his own atop his garage, the City continues to boost implementation of green infrastructure practices, including a target of 43 acres of ecoroofs by 2013. The panelists discussed their evolution from “grey to green” and how these changes will influence the fabric of their city.

At 6:00 pm the Vendor Fair was closed to the public, and the City provided a lovely reception for the exhibitors and speakers.  This casual gathering and networking opportunity was a great time just to relax a bit.  Matt and Linda Dobson (she manages BES’s Stormwater Team) welcomed Portland Mayor Sam Adams and it was easy to understand the city’s success with their ecoroof initiatives – you could feel the Mayor’s pride, commitment and passion for their projects and staff.  He extended an open invitation to all to embrace sustainable business practices and sustainable design, and let us know that the City was looking into funding low interest loans.  He also informed us that he was talking up the challenge to green his own garage roof, à la Tom Liptan!

Tom Liptan then introduced me in such a nice way, reminiscing about my student days at UGA and how I called him back in 1998 wanting to know all about his garage greenroof and what could we do to promote these earth-friendly roof covers.  I presented a short demo of The Greenroof & Greenwall Projects Database – how it began with my 1999 research study when I initially had about 30 case studies, to how it’s grown to 1,023 at the moment; why I felt the industry needed an open, free resource for compiling and maintaining a clearing house of sorts.

Ed was up next and Tom also shared his funny recollections of meeting him several years ago.  Ed showed some very unique and interesting” Greenroofs from Around the World” with a fast-paced show of his highlight reel.

Afterwards we were off to the richly decorated Alu Wine Bar for a glass of a spectacular local pinot noir (2007 Arterberry Maresh from Dundee Hills, OR) with a bevy of BES people.  From there Aramis, Ed and I met Patrick and Brian Heather, GRP, from SolTerra for dinner at the very funky and famous Cajun Montage – quite a noisy and fun local favorite!  Patrick and Brian have been collaborating on various projects in Portland and Seattle, and we topped the evening off with a visit to the mixed-use SolTerra offices to see some of their innovative handiwork.  SolTerra provides a variety of services and products for the solar, ecoroof, and living wall markets, and what we saw looked very impressive!

Tomorrow I’ll wrap up our visit and experiences at Ecoroof Portland 2010 ~ Linda V.

Known as “The Rose City” for its famous yearly Rose Festival and The Grand Floral Parade in early June, Portland Oregon could also be easily known as “The Eco City” or perhaps even “The Green City” because of their ongoing commitment to preserving their magnificent waterways and forests while promoting sustainable design and development through progressive urban policies and public outreach.  The last time we were there was for the 2nd Annual Greening Rooftops for Sustainable Communities Conference, Awards & Trade Show in 2004.  And we spent some time here in late 2003 when I was compiling info for my Sky Gardens ~ Travels in Landscape Architecture column on the area.  Such a beautiful city!

On March 12-13, the lovely City of Portland will be sponsor and host to their annual free Ecoroof Portland.  What an amazing city for supporting greenroofs – or ecoroofs, as they refer to them here.  Currently with about 200 projects within the city, ecoroofs cover about 10 acres, leading the U.S. in total area greened after Chicago.  And they were one of the first, if not the first, municipality in the nation to offer incentives.  As part of the Grey to Green Initiative, the City of Portland is offering an incentive of up to $5 per square foot for ecoroofs towards a target of 43 additional acres by 2013.  In the past year, the Bureau of Environmental Services (BES) awarded the incentive to 50 projects for a total of over 4 acres.  Read more in Industry Support and the City’s Incentive Project Page for more information. You can visit ecoroofs and other sustainable stormwater projects in Portland with these self-guided tours, and the City maintains an Ecoroof Blog, which is very informative, too!

The premier champion there of stormwater mitigation, and ecoroofs in particular, is Tom Liptan, ASLA.  I’ve known Tom for over 12 years, when I first contacted him about greenroofs back when I was a landscape architecture student at UGA a had “discovered” them myself.  Gracious, kind, and accommodating, he nurtured and fueled my passion for this earth-friendly sustainable technology.  And Tom has always put his money where his mouth is – he installed one of the first ecoroofs in Portland atop his garage in 1996.  The now famous Liptan Garage Greenroof served as early a demonstration project and testing grounds for a variety of factors – read more in the profile.

Designed to inform a varied audience of professionals and homeowners, the lineup of speakers will educate and inspire you to consider a greenroof on your next project.  A Vendor Fair with over 60 professionals and organizations will be on-hand both days to share their ecoroof experience, products, and services.  Featured speakers include Dr. David J. Sailor, Ed Snodgrass, and me!  Dr. Sailor is a full professor at the Mechanical and Materials Engineering faculty at Portland State University, Member Faculty of the Oregon Built Environment & Sustainable Technologies Center (Oregon BEST), and directs Portland State University’s Green Building Research Laboratory.  Ed Snodgrass is co-owner of Emory Knoll Farms/Green Roof Plants, a fifth generation farmer and nurseryman specializing in plants and horticultural consulting for greenroofs.  An accomplished speaker and writer (“Green Roof Plants: A Resource and Planting Guide”), he’s also our Plant Editor who writes his occasional column “Ask Ed“  – read my “From Llamas to Greenroofs: An Interview with Ed Snodgrass.”  See full profiles here and a complete list of all the speakers and Agenda here.

See Ed on Friday at 12:00 pm at the Welcome and Keynote Address where Environmental Services Director Dean Marriott will welcome attendees and introduce Ed as the Keynote Speaker.  His presentation will focus on the role of ecoroofs in sustainable cities.  On Saturday at noon, Commissioner Dan Saltzman will welcome attendees and introduce me – I will be presenting “Hot Trends in Greenroof Design,” a compilation of my favorite international projects from our Top 10 Lists from the past with a look at some of the new, innovative, leading vanguard and projects for 2010.  On Saturday at 4:00 pm Ed will be part of a panel where you can get some help getting started on your own ecoroof project – “The Ecoroof Doctors are IN,” along with Tom Liptan, David Elkin, and Alice Meyers from BES, and Patrick Carey of hadj design, a Green Roofs for Healthy Cities trainer, and our Architecture Editor.  Patrick writes an occasional architectural column entitled “A View from the Sky Trenches,” where he selects and discusses pertinent greenroof industry topics.

Don’t miss Ecoroof Portland!  It will run on Friday and Saturday, March 12 & 13, 2010 at the Leftbank Annex, located at 101 N. Weidler St in downtown Portland.  It’s very close to the Rose Quarter – you can find directions by clicking the following link.  Learn all about Ecoroof Portland 2010 at the City’s BES website.

If you can attend, please stop by and say hello!  Happy greening,

The first ever CitiesAlive! World Green Roof Infrastructure Congress will be held in Toronto in a couple of weeks and Greenroofs.com will be there.  In partnership with the City of Toronto, the World Green Roof Infrastructure Network (WGRIN), and Green Roofs for Healthy Cities (GRHC), CitiesAlive! is expecting a great turnout with over 1,000 participants.  Addressing the theme “Green roof infrastructure as a global solution to climate change,” the congress will host over 60 internationally renowned speaker presentations and expert roundtable discussions in greenroof design, policy, research and emerging trends in green infrastructure, and an industry trade show.

We’ve had multiple questions from readers about this conference, in terms of comparing it to the annual Greening Rooftops for Sustainable Communities Conference, which also offers all of the above.  GRHC is a founding member of WGRIN, who has been planning this congress for some time now, and since Toronto is at the forefront of greenroof policy in North America – plus it’s their home - it’s only natural the inaugural congress should be held in this beautiful international city.  But some people are asking me why it would be beneficial to attend in Toronto, especially if they had just come to Atlanta in June.  They’ve asked me about the focus of CitiesAlive! since we’ve always had global views and speakers at the seven Greening Rooftops for Sustainable Communities Conferences so far.

I recently asked Steven Peck, President, Green Roofs for Healthy Cities, these questions on the differences between the two events, and he shared his views with me:

“There are a number of important differences. The main ones are that the focus of CitiesAlive! is on how vegetative technologies, including urban forests, can help us mitigate climate change and adapt cities to the negative consequences like heat waves and severe storms. We have invited various experts from around the world to give presentations. It is much more focused than our annual conference which includes a wider range of topics. Another major difference is that WGRIN is the co-host of this event, which is scheduled to be held in Mexico City next year. This event will have a greater international flavour and we are having a Mexican fiesta and international showcase of projects on Wednesday, October 21 at the Toronto Botanical Garden.

“We are also not having North American industry programs like the Awards of Excellence but a Student Design Contest instead – where 22 groups of students from around the world are redesigning a city block with multiple forms of green infrastructure for maximum sustainability benefits.

“We are also celebrating and acknowledging the policy and program leadership of the City of Toronto, which passed the first green roof construction standard and mandatory by-law for new buildings in North America.”

And Steven concluded, “So, CitiesAlive! is a different program with a broader scope of green technologies but more of a focus on positive climate change impacts. Cities Alive! is going to be a really unique, one-time event.”

OK, so we can expect greater green infrastructure beyond greenroofs and green walls, encompassing broader living architecture technologies, with greater international focus and flavor – got it!  I love the inclusion of the international student design competition, “Transforming the Face of Buildings” – it sounds very promising, where students were asked to rethink the connection between built and biotic landscapes.  It will be very interesting to see the entries.  Also of note, the Congress is offering courses, many sustainable project tours, CitiesAlive! delegates can learn more about the new Toronto Green Roof Bylaw, and the Canadian Green Roof Professional (GRP) Accreditation launch will be held on October 19, 2009. 

Speaker highlights include Paul Kephart (Executive Director, Rana Creek, USA); Dusty Gedge (President, European Federation of Green Roof Associations and livingroofs.org, England); Sadhu Johnson (Chief Environmental Officer, City of Chicago, USA); David Yocca (President, Conservation Design Forum, USA); Don Delaney (Environmental Solutions Manager, Flynn Canada); Sable (Director Marketing & Education, Green Screen, USA); and Jeffrey L. Bruce (Principal, Jeffrey Bruce & Co., USA).   Download the Agenda here.

The CitiesAlive! 2009 International Green Infrastructure Congress will be held from October 19 – 21 2009 at the Sheraton Centre Toronto Downtown, 123 Queen St. West, Toronto, ON, Canada.  Visit www.citiesalive.org for more information and to register.

It’s great to see the international greenroof community coming together again, and we’re very happy to be attending the CitiesAlive! World Green Roof Infrastructure Congress, too. We hope to see many of you there, including our Student Editor, Christine Thuring, the Green Wall Editor, George Irwin, and the Architecture Editor, Patrick Carey.  Aramis and I look forward to taking the Toronto Sustainable Roof Bus Tour, sponsored by Tremco and Bioroof, and enjoying the sights and sounds of awesome downtown Toronto with friends and colleagues.

After almost seven weeks of intense scrutiny and review, Green Roofs for Healthy Cities (GRHC) has relased the names of their first “graduating class” of GRP’s, or Green Roof Professionals (download the Press Release “First Green Roof Professionals (GRPs) Announced” of July 21, 2009 here.  These hardy 100+ represent the inaugural group of professionals across multi-disciplinary fields to sit for and pass the GRP exam, held in Atlanta on June 5, 2009 at the 7th Annual Greening Rooftops for Sustainable Communities Conference, Awards & Trade Show.

The purpose of the GRP exam is to establish greenroof professional viability in our growing industrial sector.  Jeffrey L. Bruce, Chair of Green Roofs for Healthy Cities, whom I interviewed in May said, “We are very pleased with the caliber of the new GRPs and the fact that they come from both the green arts side, i.e., the living components of a green roof, and the black arts side, i.e., the nonliving components. Industry experts from both the black and the green arts have worked hard over the past six years to develop training materials and a professional exam that covers best practices across the spectrum of professionals, in order to improve multi-disciplinary knowledge and practice in the field.”

Congratulations to the new designees and so many people involved in the whole process!  Many of our friends, colleagues, and several of our Contributing Editors received their GRP designtion, including Kelly Luckett, The Green Roof Guy; Patrick Carey, The Architecure Editor; and Haven Kiers, The Design Editor.  In fact, Kelly was on the GRHC Training and Accreditation Committee which developed the Green Roof Professional Accreditation program, and he can attest to the countless hours put in by all to ensure quality, integrity and equity.  But don’t feel too badly for them as, of course, everyone on the GRP Training and Accreditation Committee was grandfathered in and didn’t have to take the actual test!

So what about me?  Remember when I said I was going to take it, too, and to join me?  Yeah, well that never happened.  Long story, but kind of typical for me, I waited too long to actually sign up for the exam and when I tried, it was closed.  It was probably a blessing in disguise, because I hadn’t studied at all and was going to cram for the test at the last minute…  Now I can plan accordingly, study like a normal person and take the GRP exam in any of these North American cities this fall: Chicago (Sept. 18), New York (Oct. 16), Toronto (Oct. 19), and Seattle (Oct. 30).  And since I am also a greenroof designer, I do think it will be a good thing for me to have, along with my BLA and LEED AP.

So, did you take the test?  What do you think about it?  Share your comments here with us.

See the complete list of Green Roof Professionals in the latest issue of the Living Architecture Monitor online or download a PDF from Green Roofs for Healthy Cities here.  Once again, a job well done to all!
