GPW: ESRI Canada’s Garden in the Sky

May 19, 2010 at 5:54 pm

As you know by now, ESRI Canada’s Garden in the Sky  in Toronto, Canada  is the winner in our  first contest here at Greenroofs.com, the 2010 Love the Earth, Plant a Roof!  Earth Day Photo Contest, and was featured as our Greenroof Project of the Week (GPW) from May 2, 2010 through May 9, 2010.   Submitted by Josephine Chan, Public Relations Specialist, Marketing, with ESRI Canada, this project received a whopping 735 votes!   Well, Josephine is a marketing specialist and  should be  commended on doing a great job of  getting the word out to vote for her project!

 

Although this really was a popularity contest, nonetheless, this “Garden in the Sky” is a stunning example of  collaboration, resulting in a thoughtful,  peaceful, and inviting  greenspace in an otherwise dreary, hot urban roofscape canyon typically found in our core downtown areas.   I asked Josephine why she felt the ESRI Canada living roof was special:

“The green roof is a great project because it provides access to nature in an urban environment.   It reflects the passion for the environment and collective creativity of ESRI Canada’s staff, who were consulted and encouraged to submit suggestions for the design of the green roof.   The result is a colorful, accessible and functional rooftop garden that significantly enhances our workplace and the environment.”  ~ Josephine Chan

ESRI (Environmental Systems Research Institute) Canada is a geographic information systems software company who wanted an ecological roofing alternative for their ninth-story  headquarters.   According to an article in unlimited Magazine, company president Alex Miller saw big potential:

“We’re an environmental company.   Our business is building geographic information systems for our customers.   We wanted to set an example of what a company could do, for a relatively small amount of money overall, at improving the sustainability of our surrounding environment.” ~ Alex Miller

The greenroof was designed by Scott Torrance Landscape Architect of Toronto, who also  conducted  a Green Roof Feasibility Study for the ESRI Canada Head Office in 2007.    The design encompasses several zones of outdoor rooms  for circulation purposes,  and also reflects the indoor plan.

The project  was  installed and is maintained by Gardens in the Sky, Flynn Canada.   Not including the planters, the 7,500 sf  installation is a pre-vegetated LiveRoof  Hybrid  greenroof system combining 4″ LiveRoof Standard and 6″ LiveRoof Deep modules.    Josephine told us about several challenges that  were encountered during the design and implementation of the roof garden.  The first step was convincing the landlord, Crown Property Management, that it was an idea worth pursuing.

“Fortunately, they are committed to making their buildings more energy efficient and sustainable.   They agreed that a green roof would be a valuable enhancement and covered the cost of re-roofing the structure on which the garden would be laid.  Capital costs for the green roof were in the range of $25 to $35 per square foot.   The investment the company allocated for the project was substantial.   However, it knew the benefits would far outweigh the costs and proceeded with the project despite the severe economic downturn.”  

 

ESRI Canada faced other challenges such as winds, loading capacity and logistics for a project located in a busy commercial area of east Toronto, and shares the following items that needed to be addressed:

“Wind velocity, particularly nine stories above ground, needed to be factored into plant selection and installation.   An 85-ton crane was used to lift a total weight of 260,000 pounds of plant modules, including 100 yards of soil, 56 planter boxes and 4,000 individual modules of live root plants.   Further complicating the process was logistics.   Crane availability and other logistical considerations in a busy office building meant that work could only be done on Saturdays and Sundays.   This was carried out with a crew of eight working 12-hour days for two weekends in early May 2009.”   Another reason for doing the crane work  over weekends was so that the fire routes were not blocked during working hours.

One other interesting  challenge was  the need to access window washing anchors set within the gravel, which was accomplished through Scott Torrance’s design (photo below from Treehugger).   The landscape architect positioned the  plantings “so that the lines for the window washers go between them.  The gravel also keeps people on roof away from the glass.”

 

Kees Govers, BSc (Agr), of LiveRoof Ontario Inc. adds perspective from the installation process:   “In May 2009, Gardens in the Sky devoted two consecutive  weekends to the installation.   On the first Saturday, all the planters and furniture were hoisted to the 8th floor balcony and positioned, and on the second Saturday the LiveRoof modules were craned up and installed along with the irrigation and the pathways.

“The pathways were all preloaded in LiveRoof modules and were simply installed as any other module.   As a result, the entire green roof is truly portable.  It would take approximately one day to completely remove the entire green roof without a trace, if and when the time came.   Because LiveRoof utilizes patented “˜hoppits’ as conveyance for the modules to the rooftop, even grasses and perennials can be completely full grown ready for installation in the nursery and installed without any damage.  As a result, the green roof is truly finished on the day it is installed rather than requiring another two to three years of growth.”

 

These two photos below were taken by Kees  approximately two weeks after installation was completed (late-May, 2009):

 

Kees explains that unlike other modular systems, LiveRoof doesn’t stack their modules.   “We also use only a minimal amount of stretch wrap to prevent overheating of the plants.   As a result we can ship fully grown grasses, perennials and sedums without any shipping damage to the plants and without having to utilize refrigerated trailers.   The elevators are removed during installation to create a monolithic green roof without visible modules.”

“We always utilize the living mulch principle when executing plant designs.  No deciduous plants are used without an evergreen groundcover underplanted.  Because everything is full grown and already maturing at the time of installation, there is never any exposed growing medium.   As a result, wind erosion of the growing medium is virtually non-existent even when the deciduous plants have gone dormant.” ~ Kees Govers

Patrick Biller, Green Roof Maintenance & Installation with Flynn Canada, Gardens in the Sky, believes the ESRI is a unique project.  “It has all the typical Sedums and grasses that other LiveRoof systems have, but it also has an area devoted to plants that are unique to green roofs.  A lot of rock garden Sempervivums were used, as well as thyme and Nepeta.   The sculpture in the center is unique and points in the direction of the city with the CN Tower in the background.”   From a maintenance point of view, Patrick says that the  LiveRoof system is quick to install, fills in quickly, and reduces the maintenance challenges, and that everything about the system is efficient.   Other than a few select perennials such as coreopsis and evening primrose dying out,  the greenroof  has filled in very nicely.   In early May Flynn Canada/Gardens in the Sky planted some more coreopsis and yarrow.

“I had the privilege of doing the spring clean-up on this site this spring, and I enjoyed myself thoroughly.  All the hustle and bustle of the city, with the Don Valley Parkway directly underneath and general road noise are masked up there, and it feels like an oasis.  Not very often do we do projects that can actually separate you from your surroundings, offering a tranquil space for people to enjoy.  I wish more projects were like this one!” ~ Patrick Biller

Despite the many site  challenges, ESRI Canada believes the company was able to “transform a previously dreary concrete terrace into a lush green roof that provides important environmental and business benefits, including improved air quality, lower energy consumption for air conditioning and reduced stormwater runoff.   Previously, you would be met by dust and highway noise when you stepped out onto the terrace.   Now, employees and visitors can walk out to green outdoor space for formal meetings, corporate events and informal lunch breaks.   They can enjoy the breathtaking view of perennials and tall grasses intermingled with sedums that can also be seen from inside and neighbouring buildings.   Birds and butterflies have also become frequent visitors to the green roof.   It has been transformed into a colourful, living garden enjoyed by many.”

Josephine gave us her personal reflections on the greenroof and its contribution to a healthier Earth:   “It’s been almost a year since ESRI Canada’s green roof was installed.  It was about the same time when I started with the company.  I have never worked in an office with a green roof before so I was, and still am, extremely impressed with ESRI Canada’s environmental effort and proud to be part of a company that is committed to being green.

“From inside the offices, you get seamless views of the garden, which is broken into zones that extend the interior space.   It’s a refreshing place to relax during breaks and provides a great venue for more formal corporate gatherings.  It’s designed with several walkways, so you can tour the roof and look closely at the more than 50 varieties of shrubs, flowering plants, grasses and trees.

“We’ve hosted numerous tours for customers, partners, journalists, and tenants in the building and surrounding buildings who are curious to see the green roof.  They are always amazed by how cool and quiet it is there, given that the busy Don Valley Parkway is just below.   Birds and butterflies are also frequent visitors.  It’s a living garden enjoyed by many.   In addition to providing weather and noise insulation, it retains stormwater and delivers significant energy cost savings.   It also serves as an excellent demonstration of and inspiration for preserving nature and caring for the environment.  “

Kudos to  all the stakeholders for a wonderful project and in particular  to Josephine Chan of ESRI Canada, who says she’ll be donating the $100 prize to a local charity that protects migratory birds.   Josephine adds, “I love seeing them on the green roof!”

Lloyd Alter from Treehugger.com created two videos about the project for his article “Prefab, Portable Green Roof Installed In Toronto” of October 5, 2009, where he interviewed ESRI General Manager John Kitchen and the landscape architect, Scott Torrance.     Also read more from  the  project  profile in the Greenroof & Greenwall Projects Database, and watch a short video about ESRI Canada’s Garden in the Sky below:

2014 is the Year of Action – Plan, Engage and Network!

January 30, 2014 at 4:18 pm

Happy New 2014 to everyone in our greenroof and greenwall community, and to your families as well!

While implementing (and breaking) our New Year’s resolutions and planning for the new year, the world has also been dealing with some challenging freak weather lately.

As in other areas of the southern United States, here in the metro Atlanta area we just experienced a devastating near complete shutdown of interstates and highways after Tuesday’s snowfall – in fact, the governor issued a state of emergency for the entire state of Georgia.  Due to the snow, heavy traffic and sheets of ice, motorists were inching by or stranded for hours on hazardous roads, children had to stay overnight at schools (reports say about 8,000 students across Georgia and Alabama woke up yesterday in school gyms or on buses), and we have experienced thousands of accidents.  At present, there are still hundreds of abandoned cars all over the roadways.

“Tennis courts like a sauna” and “extreme heat.” – After 2013’s recently being declared Australia’s hottest year on record, Melbourne experienced three consecutive days of extreme heat above 40°C during the recent Australian Open.  Some spectators, ball kids, and tennis players became ill or fainted during these sizzling hot days when temperatures reached up to 109°F (43°C) .  To avoid heat stress they placed bags of ice on their heads and necks between points and the scorching heat even halted play.

2014AustralianOpen-TheTelegraph_AFP

Results of global warming?  Maybe.  At least these are examples of some major temperature extremes in just the first month of our new year!

On Tuesday, here in the U.S. we watched President Obama’s fifth State of the Union address before Congress. Just a couple of his economic proposals regarding climate and energy highlighted working with states and communities on climate change resiliency and cutting pollution plus urging our Congress to end tax benefits for the oil industry and use revenues to invest in advanced vehicles that use cleaner fuels.  Awesome.

Obama says let’s make 2014 “a year of action.”  Certainly we cannot continue to heavily depend on high-carbon fossil fuels but must continue to strive towards a sustainable approach to drive innovation and embrace clean renewable energy solutions.

In our greenroof and wall world we all, too, must take a look at how we conduct business and how we can make it better – more profitable, more sustainable, more inclusive.  What are you doing within your organization to lower costs, increase sales or open up areas of debate?  Share your 2014 stories and strategies with us – we’d love to share your experience through a Guest Feature Article or blog post here on Sky Gardens.

We are convinced that information sharing and open communication are key to a vibrant, growing living architecture industry.  As markets continue to open up across the world through private and public support, opportunities abound – locally and globally.

Along those lines I just wrote a chapter in the upcoming book entitled Green Cities around the World to be published soon by PRONATUR (a Spanish rooftop agricultural group head by Dr. Julian Briz and Dr. Isabel de Felipe, member of the World Green Infrastructure Network or WGIN) and WGIN itself.  It’s entitled “Greenroofs & Greenwalls in the New Millennium: The Influence of the Age of Technology through Online and Social Media.”

I present an overview of how the advancement of greenroof and wall design, construction, and the industry itself has flourished since the turn of our new 21st century with the advent of the widespread use of the Internet, through its innate entrepreneurial spirit, and the continuing rise of information technologies.

InternetMap1024

Did you know that, according to Internet World Stats, by December 31, 2000 the Internet had 360,985,492 users worldwide and by June 30, 2012 the amount had exploded to 2,405,518,376 users?  Our views of culture, social relationships, and how we interact in the world of e-business have forever changed through electronic media and smart devices.   The Internet has altered the way we do business forever – surfing the net has become a way of life around the world.

SocialMediaGraphic

And, as most people know, social media is no longer an emerging new world in cyberspace, but an exponentially growing online reality of fantastical proportions.  The impact and importance of social media and how it is changing the landscape of both the personal and professional worlds cannot be overstated.  Here are some recent figures of the most widespread social networking websites used to create new online business contacts and friendships with people who share similar interests:

Facebook  (1.26 billion users as of December, 2013);
LinkedIn (259 million users as of October, 2013;
Twitter (500 million total users as of October, 2013):
Google+ (540 million monthly active users as of October, 2013):
Pinterest (70 million users as of July, 2013;
Tumblr (216.3 million monthly visitors as of May, 2013):
Flickr (87 million users as of March, 2013);
and Instagram (more than 75 million monthly active users as of December, 2013).

VS2013_Campus

This brings me to planning for our third virtual conference, the Greenroofs & Walls of the World™ Virtual Summit 2015: Connecting the Planet + Living Architecture.  We firmly believe this platform is the future, a synthesis of technology and social media – education, entertainment, and social networking – interacting directly with people across the world in our highly targeted community.  We’ve been searching for a new, lower cost medium to be able to broadcast the amazing video content provided by so many brilliant individuals and hard working organizations and further engage everyone in lively video, audio and text chatting.

VS2013Agendapage

While strategizing new relationships and collaboration partnerships, we continue to investigate out-of-the-box ideas and certainly welcome your input for an even greater, fun and vibrant virtual summit in 2015.  Next month we’ll start airing our 37 videos from our Greenroofs & Walls of the World™ Virtual Summit 2013.  We hope these keynote, panel sessions, and individual videos will inform and inspire you!

GPW: Haworth Corporate Headquarters

September 10, 2011 at 10:13 pm

Greenroofs.com Project of the Week: 9/5/11
Haworth Corporate Headquarters
Holland, MI, USA
45,000 sf. Greenroof

Year: 2007
Owner: Haworth, Inc.
Location: Holland, MI, USA
Building Type: Corporate
Type: Extensive
System: Single Source Provider
Size: 45,000 sq.ft.
Slope: 30%:
Access: Inaccessible, Private

Project Description & Details

The new Haworth Corporate Headquarters, also known as One Haworth Center, in Holland, Michigan is a 300,000 sf living testament to adaptable, user-focused, sustainable design.  It has a sun-filled day-lighted atrium with flowering sedum plantings on the 45,000 sf modular greenroof, and – along with over 750 workstations with access to daylight and naturalistic views, among other credits – it has been certified LEED-NC Gold.  In line with their corporate sustainability objectives Haworth says, “The fully renovated environment will function as a living laboratory of innovative organic workspace solutions.”

Its west end slopes down six stories to grade while also narrowing in width from 60 feet at the top to 24 feet at the bottom, so when the manufacturer of its aluminum edging expressed concern about hydraulic pressure during severe storms, horticulturist and system designer Dave MacKenzie of LiveRoof shared the concern with the design team, which prompted an engineering review.  In a collaborative effort, modules were modified for increased subdrainage and three elevated steel barriers were installed to help regulate flow.  Larger drain holes also were drilled into the edging at the base. As a result, the One Haworth Center was planted with a Hortech / LiveRoof Modular Green Roof System consisting of a Standard 4″ System with recycled interlocking modular units.  The highly reflective greenroof accounts for the following LEED Contributions in SS (Sustainable Sites) and MR Material Resources): Heat Island Effect-Roof; Recycled Content; and Regional Materials.  Although the greenroof is inaccessible, it is very visible and the HQ is open for tours.

Additional Info

The Haworth Corporate Headquarters is a  global company operating in over 120 countries worldwide and is still family-owned.  It rebuilt its new headquarters  adjacent to its existing million-square-foot plant because Dick Haworth,  the company’s chairman,  liked the potential for “reality checks.”  His desire was to partner with customer needs and utilize the company’s knowledge and research to help make work spaces healthier and more productive.

Regarding the renovation strategy, in 2008  Dick Haworth said via  Walk the Talk, in Metropolis Magazine that  “It was central that we set a whole new standard, take what we’ve learned in our research, and practice what we preach.”  Here’s a graphic below of what they hoped the finished building could emulate – excellent job!

Located about a half-hour drive from Grand Rapids, Michigan,  the previous corporate center was less than appealing.    Metropolis continues and says:

“…the scary concrete ­bunker where workers had holed up since the early 1980s was replaced by an airy three-story sweep of glass and steel that slices across its 320-acre site of grasslands and marshes like a sleek airline ­terminal.  A soaring new atrium runs the facade’s entire 1,000-foot length, glistening in polished white terrazzo floors and punctuated by olive trees, splashes of red, and aerial stairways, all spanning panoramic views to the outside.”

It had so little natural light – see above – that the employees used to joke that the place could double as a mushroom farm!  The aerial photo below shows its new design is a far cry from its former self:

Since the new headquarters doubles as a showroom, Perkins + Will branded the space with Haworth products and its signature red and white:

Covering the new light-flooded, three-level north-facing atrium, project principals say that the Gold LEED-NC building’s 45,000 sf vegetated roof has been instrumental in achieving corporate sustainability goals.

The LiveRoof ® Standard 4″ modules were chosen because LiveRoof ® came fully vegetated at installation, and its patent-pending soil elevation technology allowed sharing of water, nutrients and beneficial organisms across the entire rooftop for Natural Function & Natural Beauty.  It also minimizes hot, wet, and dry zones, and avoids compartmentalizing the growing medium into an unnatural container as is the case with some other modular systems.

Haworth was able to recycle plastic scrap from their local plant into the LiveRoof modular units used on the roof, thereby helping to close the waste loop.

Although  Perkins + Will designed  the new Haworth Corporate Headquarters 20% larger than the old structure, the plan was for it not to consume any more energy. And  One Haworth Center has received much attention for its many sustainability efforts.  Last year, Eva Maddox of the Huffington Post, founder of Branded Environments, and design principal with  Perkins + Will understandably selected it as one of the Top 10 Green Roofs Across the Globe:

“I was fortunate enough to lead our firm’s Branded Environments team, in collaboration with our architectural practice, on one of our largest projects with long-term client Haworth.  The company’s Holland, Michigan headquarters and manufacturing facility achieved LEED Gold certification for a total renovation that featured a spectacular, sloping green roof.  This aspect not only aligned with the company’s sustainability platform, it made (and continues to make) a lasting impression on visitors and employees alike. ” ~ Eva Maddox, Huffington Post

Since we know the greenroof is  inaccessible  except  for maintenance, below is a photo from Haworth, Inc. which was clearly designed as a photo-op for their sleek chair line:

In 2009, Time Magazine recognized Haworth in its “Green Design 100,” Time’s round up of the best in sustainable design in the Architecture category:

“Call it responsibility or accountability.  Or simple popular demand.  The rarefied world of design is embracing the environment as never before. Top architects are implementing revolutionary methods. Fashion and furniture mainstays are manufacturing products using sustainable materials.” ~ Time Magazine

In 2008, BusinessWeek/Architectural Record recognized Haworth with its “Good Design is Good Business” Award.  The contest honors buildings that adhere to the sponsors’ semi-official tagline: “Good design is good business” and called  the final product of  Haworth’s new headquarters building “striking.”  When Chief Executive and President Franco Bianchi decided to replace Haworth’s headquarters he not only wanted to attract more potential customers from across the world to visit, he also:

“…wanted the space to act as an on-the-spot demonstration of the office systems he and his team sell, including equipment for every aspect of office life, from cafeteria to conference room.  The result includes a swooping glass-walled atrium that runs along one side of the building, flooding the three floors of offices with natural light.  Furnishings are entirely from Haworth, turning the site into a massive showroom.  The $40 million investment is paying off. ” ~ Bloomberg Businessweek

Greenroofs.com’s “This Week in Review” on GreenroofsTV: August 26 & September 2, 2011

September 4, 2011 at 12:08 pm

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 September 2 and August 26, 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 September 2nd, 2011 as well as for last week, August 26th on  GreenroofsTV.

Project of the Week

–  Our project of the week this week is the  extremely cool 8 House built in 2010 in Copenhagen, Denmark.  And our project of the week last week was the Duke University Ocean Conservation Center built in 2010 in Beaufort, North Carolina.

–   The 8 House is a 61,000 square meter bowtie-shaped mixed-use building of three different types of residential housing and 10,000 square meters of retail and offices which make up Denmark’s largest private development. It stacks its lively urban neighborhood into horizontal layers of typologies connected by a continuous walking and cycling path up to the 10th floor which creates a three-dimensional urban neighborhood where suburban life meshes with the energy of a big city. Two sloping green roofs totaling 1,700 square meters are strategically placed to reduce the urban heat island effect as well as provide the visual identity to the project and tying it back to the adjacent farmlands towards the south. The architects wanted to design a “long, coherent house with immense differences in height, creating a strong inflow of light and a unique local community with small gardens and pathways that channel your thoughts into mountains in Southern Europe and memories of a childhood home.”

–   The Duke University Ocean Conservation Center houses a lecture hall, teaching laboratory and commons area and uses geothermal pumps for heating and cooling, solar panels for hot water and photovoltaic rooftop panels to convert sunlight into electricity. Local building materials, like yellow southern pine and Atlantic white cedar and recycled wood, are used throughout the 5,600-square-foot center. In 2008, the Ocean Conservation Center was awarded Gold LEED certification by the U.S. Green Building Council and in 2009 was awarded a Green Building Wood Design Award from Woodworks. The extensive green roof was installed in 2010 over the low-slope portion of the Energy Star roof and is a Xero Flor pre-vegetated extensive system, with specialized components to secure the green roof from high wind coastal exposure. Living Roofs worked with Xero Flor America and Frank Harmon Architects to design the green roof system and the irrigation which is supplied by a rainwater catchment system.

– “In the News“

–   Tyler Falk of SmartPlanet, reveals “NYC’s urban agriculture potential.” He shares some interesting insights in a new report from the Urban Design Lab at Columbia University’s Earth Institute that explores New York City’s urban agriculture potential. The report showed nearly 5,000 acres of empty land that would be sufficient for farming throughout the five boroughs, and that urban agriculture can have a huge impact on food security in neighborhoods where fresh and healthy produce is needed the most with help from more city farmers. He found some more interesting information in the report like how urban farms equal green infrastructure, and that rooftops are numerous in New York City but are not being utilized enough for urban agriculture and more. Check out the full article for more information and a link to the complete report: “The Potential for Urban Agriculture in New York City.”

–   Stephen Totilo of Kotaku, talks about “The Coolest Things in Nintendo’s American Headquarters (And One Uncool Thing).” Well the only “uncool thing” he says about the headquarters is that they don’t “let visitors take pictures of the best parts of the building.” When you walk into the headquarters of Nintendo of America in Redmond, Washington, you have to sign an electronic waiver promising you won’t bring firearms, will keep any Nintendo secrets you hear to yourself and won’t take any unauthorized pictures. There are a few spots you can take some photos, which he did, so be sure to read the full article check to them out. The Nintendo headquarters was awarded Gold LEED certification from the U.S. Green Building Council in May of 2010. Among other eco-friendly additions, they have bamboo floors on each level, daylight sensors near the windows that dim or brighten interior lights based on the natural light in the room, heat and motion sensors in the many conference rooms, and there’s a 75,000 square foot Sedum living room to top it all off.
