Project Description & Details

Demonstrating the University of Pennsylvania’s leadership in the emerging field, the LEED Gold certified Krishna P. Singh Center for Nanotechnology is a premier $91.5 million state-of-the-art research and teaching laboratory facility. The 78,000-gross-square-foot facility houses several multi-user experimental laboratories critical to advanced research and development in nanotechnology, woven together by collaborative public spaces that enable interaction between different fields. Defined by a 1.7-acre central campus green at a new gateway to the campus, the building also features a courtyard, public galleria, a forum space, high-profile conference rooms, and two green roof spaces.

Responsible as architect and for site design, WEISS/MANFREDI focused the laboratories around a new central quad. This convergence of architecture and landscape at the heart of this project provides a new indoor/outdoor open space for interaction, allowing panoramic exterior views, opening the sciences to the University landscape, and making research activities highly visible. The green roofs crown the 68-foot cantilevered volume – one lower, partially accessible intensive roof with native plants, and one upper extensive roof with sedums. They are considered a “miniaturization” of the building’s courtyard. The Roofmeadow Type III Savannah Intensive Vegetative Roof Assembly was installed utilizing 3 inches of drainage media with varying depths of growing media planted with assorted sedums and native trees, perennials and grasses.

The Krishna P. Singh Center for Nanotechnology is the 2015 Recipient of the Institute Honor Awards for Architecture from the AIA.

Greenroofs.com’s “This Week in Review” on GreenroofsTV: April 13, 2012

April 16, 2012 at 1:37 pm

Each week you can expect to learn What’s New here on Greenroofs.com through our “This Week in Review” video.  Here is the transcript from April 13, 2012 from our daughter, Anjuli – click on the photo below to see the video, or here.  Enjoy!

- Hello, I’m Anjuli Velázquez and welcome to “This Week in Review” for April 13th, 2012 on GreenroofsTV.

- Project of the Week

-  Our project of the week is the  Green Wall Ferrara, built in 2009 in Ferrara, Italy. This project entailed converting a garden space in the courtyard of a private estate and there was little room for a traditional garden, which led the designers to plant on the walls.  The Optigreen Living Wall Garden system was installed and a beautiful vertical garden was created, resulting in a very soothing effect.

The core unit of the Optigreen Wall Garden system solution is a high-grade, substrate-filled aluminum cassette system which can be planted on site.  The horizontal suspension rails support the Wall Garden elements which are hooked into the rails. The irrigation system is fully automatic with a blending unit for fertilizer and herbicides. Three thousand plants with about 50 different species were planted into this 5 meter high, 120 meter squared private green wall.

- “In the News“

-  Matthew Camp of The Alestle, talks about “Unseen green grows on SIUE rooftops.”  He says several buildings at the Southern Illinois University Edwardsville are becoming a part of a greener tomorrow with the additions of rooftop gardens.  Civil engineering professor and acting environmental program coordinator, Susan Morgan, says there are currently three buildings on campus that have the gardens and there are several more planned for the future.  Biology professor Dr. Bill Retzlaff [one of our contributing editors] says the typical green roof may cost $11-50 per square foot, SIUE’s gardens are at the cheaper end, and “since 2004, more than 100 students have worked on the project.  SIUE is a leader in green roof research in the United States.  They are one of the five or six bigger institutions that conduct research on green roofs.”

Mechanical engineering professor Serdar Celik says they don’t use traditional soil for the roofs – they have been experimenting with different inorganic rocks and different varieties of sedum, and also that the students do experimental testing and theoretical analysis.  They take temperature readings, measurements of stormwater runoff weight, solar radiation, plant coverage, and more.  Celik also says that since we are aware of the global warming issue, the rooftop gardens are one of the solutions toward environmentally friendly sustainable design standards.

- Sandy Bauers of the Philadelphia Inquirer, reports on “Philadelphia embarks on green stormwater management.”  The U.S. Environmental Protection Agency gave the go-ahead to Philadelphia’s $2 billion plan to manage its stormwater with green methods like porous pavements, green roofs, and planting more trees.  EPA Administrator Lisa Jackson said “the city has earned a place as a national and global leader on sustainable innovation and clean water protection.”  She joined Mayor Nutter and other officials at the Fairmount Water Works to sign the agreement for a 25-year plan that has been described as one of the most innovative and ambitious in the nation, it will transform how the city looks but more importantly how the city handles its stormwater.

Other cities like Syracuse, Cleveland and New York will be following in Philadelphia’s footsteps, and hopefully they’re the first of many cities around our country to enhance their cities and beautify their streets.  Later this month, a nonprofit water sustainability organization, the Clean Water America Alliance, will name Philadelphia one of the six national 2012 prize winners for its stormwater plan.

Additional Info

The City of Philadelphia is fast becoming a very green-oriented city due to Mayor Michael A. Nutter and the efforts of many.  The City is currently working on a $2 billion stormwater plan to rethink  the way the city deals with rain.   And, their Stormwater Management Practices Design Guidelines include specifics on greenroofs.

“The 25-year plan, which has been hailed as a national model, envisions green roofs on office buildings, porous pavement on city streets and parking lots, and plants and trees with tubs of gravel below ground to hold water and stall runoff in a storm.” ~ Philly.com of June 2, 2011

See the most recent version of the Philadelphia Stormwater Management Guidance Manual (Version 2.0 revised 4/29/2011).

Specifically pertaining to greenroofs, the City  offers up to $100,000 in business tax credits.   For more info, download the Business Privilege Tax Application for the Green Roof Tax Credit, Philadelphia Code § 19-2604(8).

The Free Library of Philadelphia, Parkway Central is located on Logan Circle at 19th and Vine Street in Philadelphia and the greenroof project was initiated by Fredda Lippes, RA, LEED AP, Dept. of Public Property and Mayor’s Office of Sustainability for The City of Philadelphia.  The Library’s greenroof was designed by Moshe Safdie and Associates, the Library’s nationally-renowned architect of the Parkway Central Library’s expansion project and numerous other high-visibility living roofs (such as the Vancouver Public Library).  Sustainability and green building practices are being incorporated into the new 180,000 square-foot addition, and the Library is seeking a silver LEED designation for the new building.

“I want to commend all of those involved in making this vision a reality.  This project is another example to cities across the country of what can happen when many different sectors – government, business and non-profits – work in partnership towards a common goal.” ~ Mayor Michael A.  Nutter

Completed at a cost of $200,000, the greenroof is mostly an extensive design with some semi-intensive areas varying from a 6″ to 12″ soil depth range.   Located on the south side of the building and accessible off the 4th floor of the Skyline room, the Library greenroof terrace offers spectacular views of downtown.

Staging for the construction of the greenroof included closing of the streets by police.   Here you see the rooflite ® supersacks of growing media being trucked in:

By the way, rooflite ® says that it takes the crane operator to unload each sack in about 3 seconds!

Monitoring of the roof has included temperature recordings:

“The summer roof temperature prior to the green roof installation was recorded as 128 degrees on the ballasted areas to 170 degrees on the exposed black EPDM – the green roof surface would average approximately 30-40 degrees less than the ballasted area.” ~Delaware Valley Green Building Council

Informative signage was an important factor for The Free Library of Philadelphia to help educate the public on the many benefits of greenroofs:

- Hello, I’m Anjuli Velazquez and welcome to This Week in Review for December 2nd  on  GreenroofsTV.

-  Project of the Week

-   Our project of the week is the Free Library of Philadelphia Parkway Central built in 2008 in Philadelphia, Pennsylvania. The Free Library is one of the most visited educational and cultural institutions in Philadelphia and consists of 49 branches, three regional libraries, the Parkway Central Library, and the Library for the Blind and Physically Handicapped.   On September 29, 2008, Philadelphia Mayor Michael A. Nutter cut a green ribbon and officially unveiled the Parkway Central Library’s new greenroof demonstration project atop the four story 1927 Beaux-Arts building. The green roof was made possible through generous support from H.F. (Gerry) Lenfest, PECO, the Pennsylvania Department of Conservation and Natural Resources, and Quita W. Horan.

The 5,000 square foot greenroof is protected by an EPDM waterproofing membrane and includes 100 cubic yards of rooflite growing median and more than 5,400 plants. The Library’s greenroof demonstration represents the first greenroof on a city-owned building and is part of the Mayor’s initiative to make Philadelphia one of the greenest cities in the country. The accessible greenroof offers a beautiful view of central Philadelphia from the terrace. Green Roof Technology, formerly Green Roof Service, was also a consultant on the project.

He says “living roofs could be great branding for Northland,” and that “Hundertwasser [Austrian painter and architect who embraced the living roof concept] obviously loved this part of the world. Living roofs could add subtly to the tourist route.” The Hundertwasser toilets in Kawakawa are well known for their grass roofs. The Hundertwasser Art Centre proposed for Whangarei to have a living roof park, ramping up from the ground to the top of the building.

-   Will Parsons of Environmental Data Interactive, reports on “Green wall unveiled at Edgware Road Tube station.” The 200 square meter green wall was completed this week with a ceremony that saw the Mayor of London’s director of the environment, Kulveer Ranger, add the final piece into place. The project took only a month to complete and is part of the London Clean Air Fund, financed by the Department for Transport; and the 15 varieties of plants used in the wall will improve the air quality by trapping particulate matter coming from traffic emissions. The Mayor of London, Boris Johnson, said of the green wall: “Delivering cleaner air for London is a top priority for me and this ingenious green wall traps harmful pollution on one of our busiest roads, helping to cleanse the air at this popular spot as well as helping to soften and beautify the local environment.”
