December 26, 2011 at 5:10 pm

We’re chilling a bit here at with the whole family home for the holidays, and hope you are enjoying time with family and friends, too!

By the way, we’re keeping up our two fantastic weekly highlights through the end of the year:  The Tremco Headquarters as our Greenroof Project of the Week (GPW) profile and the Greenroofs & Walls of the World™ Virtual Summit 2011 Episode 3: Commissioner Rosemarie Andolino, Chicago Department of Aviation video (22:37).  Make sure to learn more about each if you haven’t already done so.

Amidst the cooking, eating, and playing with new Christmas toys, we’ve also got some catching up to do this week, and now’s a great time to do it.   In terms of blogging, I’ve been behind ever since Thanksgiving…we’ll also be adding a bit more projects and photos to the Greenroof & Greenwall Projects Database, working on our December eNewsletter, and more…

A couple of reminders through the end of 2011:

Make sure to order your 2012 Greenroofs & Walls of the World™ 12 Month Wall  Calendar

Greenroofs & Walls of the World™ Virtual Summit 2011 Episode 1: Charlie Miller

December 7, 2011 at 12:05 pm

As I wrote about yesterday, today we are airing the Opening Keynote Address video by Charlie Miller from our Greenroofs & Walls of the World™ Virtual Summit on and our  GreenroofsTV channel on YouTube.

Charlie Miller, P.E. and principal of  Roofmeadow (formerly Roofscapes, Inc.), has been a mentor and inspiration to me since my early days as a landscape architecture student who had “discovered” greenroofs in 1997/98.  It was a no-brainer for me to choose Charlie as our opening keynote speaker – to honor his open attitude about information sharing and to share his outlook and expertise with our Virtual Summit audience!

Charlie’s  Greenroofs & Walls of the World™ Virtual Summit  2011 keynote address is titled  “A New Place.”

“After an acquaintance of almost 20 years, Americans may think that they know green roofs.  In fact, there is much left to discover as we colonize the world of the great urban plateau.” ~ Charlie Miller, P.E.

Enjoy!  Visit  to see “A New Place” here or click below.

We appreciate your feedback, and feel free to contact Charlie directly at:

If you’re looking for an overview, make sure to see our  2011 Virtual Summit Highlights video (6:18) and our  2011 Virtual Summit Trailer (2:59).

Check back next week on GreenroofsTV for our 2nd installment from the Greenroofs & Walls of the World™ Virtual Summit 2011!

See all the Greenroofs & Walls of the World™ Virtual Summit 2011 Videos on!

December 6, 2011 at 6:18 pm

We received a lot of positive feedback from attendees  participating in our inaugural Greenroofs & Walls of the World™ Virtual Summit 2011 this past September through October about the very high quality of the speakers we offered for such an affordable price…

…And conversely, a lot of speakers have asked us if their videos would be available afterwards for viewing by the general public – those who did not pay the $49 or $25 to attend.

We certainly do not want all of the Virtual Summit’s speakers’ efforts and great information to go to waste”¦and we feel that our readership would love to see the content!

So,‘s plan is to show each of our 4 keynote speakers, 7 panel sessions, and 19 video presentations (plus my opening and closing remarks) in its entirety as we played it at the 2011 Virtual Summit – from everyone who grants us permission.

You can see my Opening Welcome and Overview now, along with the Virtual Summit Highlights Video and the Trailer on  We’ll be showing our  Opening Keynote Speaker Charlie Miller as the first featured video tomorrow, on Wednesday, December 7 followed by one or two videos a week thereafter which we’ll highlight on our Homepage.

Once played, each video will remain available to everyone on demand on the page and our  GreenroofsTV channel on YouTube.  We hope to  show everyone what they missed at our inaugural Virtual Summit and create buzz for the 2012 Virtual Summit!

If you didn’t join us for 2011 we hope you will in 2012 – then you won’t have to wait months to see all of the great new keynote, panel, and presentation videos!

We hope you enjoy each of the 32 videos and use them in the future for your reference – we’re very proud of the wonderful collaborations from around the world.  Please share with your greenroof and greenwall colleagues.

Happy greening ~

Linda V.’s “This Week in Review” on GreenroofsTV: October 28, 2011

November 5, 2011 at 10:31 pm

Each week you can expect to learn What’s New here on 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.

– To learn more about the PECO Main Office Building  greenroof, click on our project of the week photo on our homepage.

– 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.

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.
