Project of the Week

–  Our project of the week is the  U.S. Coast Guard Headquarters, DHS St. Elizabeths Campus, currently in the construction process in Washington, D.C.  The Department of Homeland Security (DHS) is consolidating its headquarters in the National Capital Region at St. Elizabeths Campus to provide a more unified and secure campus that brings together its executive leadership and operational management.  Phase 1 is scheduled to deliver in 2013, Phase 2 in 2014, and Phase 3 has a projected completion date of Q4 2016.

The Phase 1 U.S. Coast Guard Headquarters will feature several construction and operating measures in accordance with its proposed LEED Gold certification, including: over 400,000 square feet of green roof used for stormwater management consisting of wet ponds, bio-swales and step pools, and energy efficiency, enhanced commissioning of all building systems, use of green housekeeping measures after completion and occupancy, and use of low-emitting construction materials and furnishings.  Due to the variety of plants ranging from shrubs to grasses to Sedum mats from Sempergreen, there are four different soil blends on the project.  Rooflite ® growing media was specified, with Roofmeadow ® as the growing media consultant.  In all, 18 roofs, nine courtyards, and two parking garages will be covered with living roofs.

– “In the News“

–  Alistair Guthrie of The Guardian UK, asks “Carbon emissions: can buildings be elegant and efficient?”  He says some buildings have been able to integrate art and science, an important combination of being sustainable and aesthetic.  Over 70% of a typical city’s greenhouse gas emissions come from buildings and the construction industry itself consumes more than 12% of the world’s water.  It’s now more important than ever that engineers and designers work together to achieve emissions targets and meet needs for future inhabitants of our planet.

A beautifully strong example of the art-science combo needed is the living roof at the California Academy of Sciences, one of the most eco-friendly buildings in the world.  The academy’s 2.5-acre green roof blends into the surrounding Golden Gate Park and meets exceptional LEED Platinum standards.  It has reduced its water usage by 76.9% through grey water reuse, low-flow WCs, kitchen sinks and showers.  The building has saved 34% in energy by locating its photovoltaic cells around the edge of the green roof.  Other recognizable landmarks that combine beauty and sustainability include London’s Shard building and the Eden Project in Cornwall, where part of the James Bond film, Die Another Day, was filmed.

–  The Daily Mail offers you “New York’s secret skyline: Amazing aerial shots give rare glimpse of city’s hidden rooftop world.”  This incredible collection of aerial photographs taken above New York, include lush gardens, restaurants, swimming pools and tennis courts.  Thanks in part to Mayor Bloomberg’s eco-friendly roofscaping initiatives, the tops of dozens of buildings have been transformed into amazing outdoor living spaces and models for green-city living.  Pilot and photographer Alex MacLean took these stunning images for his new book, Up on The Roof: New York’s Hidden Skyline Spaces.

In the book’s introduction, architecture critic Robert Campbell writes, “Rooftops will be the lungs of the denser city of the future.  As the world urbanizes, the rooftops will connect us with nature, with wind and sun and rain and snow, with the natural processes of growth and decay.”  Over the years, MacLean has clocked up more than 6,000 flying hours and has published ten books of his aerial photography.  His new book contains 184 beautifully detailed photographs and is available on Amazon.  Check out the full article for more amazing photos!

Greenroofs.com’s “This Week in Review” on GreenroofsTV: March 2, 2012

March 22, 2012 at 3:07 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 March 2nd, 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 March 2nd, 2012 on GreenroofsTV.

–  Project of the Week

– 360 Smith Street Residences built in 2011 in Brooklyn, New York. These 19th century garden brownstones are in the heart of Carroll Gardens, Brooklyn, and have easy access to public transportation, schools, playgrounds, the waterfront, and downtown Brooklyn and Manhattan. The greenroof that sits atop the new residential building offers a unique 360 degree view of the Manhattan skyline and downtown Brooklyn. It is 6700 sq ft of relaxation for its residents while serving as a vital role in stormwater retention.

An Optigreen drainage profile from Conservation Technology was used and Sempergreen green roof sedum mats were installed for the extensive area. The rooflite ® depth is 3.5 inches for most areas; and Joe Donnelly of rooflite ® said, “What a stunning project – visual interest in all seasons. Well planned, and well executed by Future Green. Created a beneficial space for all residents of the building. When we visited the project in November 2011, the superintendent remarked on how easy his maintenance has been, and a party crew was there to set up tiki torches and equipment for a resident’s event. Add that to the list of green roof benefits – happy management and happy residents.”

Team Collaborative Future was one of the four finalists and wanted to take a different approach to shading, and the team’s lead architect, Brett Aylen, said “the vines are deciduous…in summer it’s going to be quite green, quite dense shade – then in winter it’s going to lose leaves so you get the winter sun.” The home will also feature solar panels, is set to begin construction mid-year, and you can follow the project at facebook.com/zerocarbonchallenge.

– Ben Martin of The Ecologist, reports on “Lofty ambitions: why green roofs are the future of urban gardening.” He asks, “run out of space in your garden? Look to higher ground and you’ll find an eco-friendly solution.” Greenroofs are becoming more popular across the world as more and more people are getting in the know and realizing the many benefits greenroofs have to offer. Sedum and plantation expert, Jim Blundell, lists a couple greenroof benefits: they provide a mini-habitat for birds, bugs, and butterflies, so you can have your own mini eco-system on your roof, and in urban areas where there isn’t a lot of green space, greenroofs can breathe some life back into that “concrete jungle.”

We know that greenroofs offer energy savings, reduce stormwater run-off, improve air quality, reduce the urban heat island effect, increase biodiversity and a roof’s lifespan. And Dusty Gedge, wildlife consultant, greenroof expert, and friend here at Greenroofs.com, added the benefit of the eye-pleasing qualities that beautiful flowers and plants can bring into our lives: he says, “people should view [them] as a sustainable measure, but also as a real life enhancement. The pleasure I get from it is huge.”

Building your own greenroof is no easy task, and does require research. But the benefits are worth the time and effort and we offer help for you to get started. You can visit our Projects Database to learn about specific projects all around the world and you can search our Greenroof Directory to find some manufacturers, suppliers, professional services, and more in your area to help you on your way.

GPW: PECO Main Office Building

November 5, 2011 at 7:20 pm

Greenroofs.com Project of the Week: 10/24/11
PECO Main Office Building
47,000 sf.  Greenroof

Year: 2008
Owner: PECO Energy
Location: Philadelphia, PA, USA
Building Type: Corporate
Type: Extensive & Intensive
System: Other
Size: 47,000 sq. ft.
Slope: 1%
Access: Accessible, By Appointment
Google Maps: link
YouTube Video: link

Project Description & Details

Located on top of an eight-story section of the PECO (Philadelphia Electric Company) building, the rooftop garden holds growing media up to 8 inches thick; the greenroof development is part of the company’s recently-announced comprehensive environmental initiative with a range of programs over the next several years.

This retrofit project was established with low-maintenance pre-vegetated Sedum mats by Sempergreen over a specially formulated growing media. Because of the dead load restrictions, the extensive greenroof media was designed to be extra-lightweight. The Roofmeadow Type I extensive greenroof assembly weighs 17 psf when fully saturated. The cool green Sedum carpet is punctuated by pathways, lit seat walls and Roofmeadow Type III intensive native perennial beds located over zones with a higher dead load capacity. In partnership with the Pennsylvania Horticultural Society, PECO co-sponsors public greenroof tours that attract architects, developers and engineers intent on learning more about vegetated assemblies.

Designers/Manufacturers of Record

Architect: William Craig, Architect and Re:Vision Architecture
Structural Engineer: Michael D. Pieroni, Robert E. Lamb, Inc.
Installation: Former Roofmeadow Network Contractor, Michael Furbish, Furbish Company, LLC
Vegetated Mat Provider: Sempergreen
Greenroof System: Roofmeadow Types I and III
Growing and Drainage Media: SkyGarden, Stancills, Inc.

Additional Info

Headquartered in Philadelphia,  PECO is an energy delivery subsidiary of Exelon Corporation and is the largest electric and natural gas utility in Pennsylvania, serving approximately 1.6 million electric customers and 490,000 natural gas customers in southeastern Pennsylvania.  Approximately 90% of PECO’s customers are residential and the remaining 10% are commercial and industrial.

PECO is taking major steps to demonstrate its environmental leadership.  In 2008 PECO embarked on the first phase of a five-year major environmental initiative to preserve the environment and help customers become more environmentally responsible.

Along with other initiatives and policies, the company received ISO 14001 certification, the internationally recognized standard to help organizations minimize their  impact on the environment.  See the very informative video, “PECO’s Environmental Initiative” below which also has time lapse photography of the greenroof installation:

 

For example, in addition to the 47,000 sf greenroof  atop the Main Office Building headquarters – which was largest greenroof in the state of Pennsylvania on an existing building –  the PECO Crown Lights were updated with the installation of 2 million energy-efficient LEDs (light-emitting diodes) with color capacity, resulting in a 40% energy savings.

As the result of a centuries old combined sewer system, the city of Philadelphia is plagued with a serious water pollution problem.  The PECO Main Office Building sits on the densely developed Schuylkill River banks in the heart of Center City and the roof footprint is 95% of the lot area.

In an effort to solve the onerous CSO issue and comply with the Federal Clean Water Act, the city is incentivizing green infrastructure as a key solution, with the added advantage of providing additional environmental benefits for the adjacent cityscape.  Initiatives include  Green Cities, Clean Waters Plan,  Philadelphia’s 25-year plan to protect and enhance their watersheds by managing stormwater with innovative green infrastructure.

“The Philadelphia Water Department developed the Green City, Clean Waters plan to provide a clear pathway to a sustainable and resilient future while strengthening the utility, broadening its mission and complying with environmental laws and regulations.” ~ Green Cities, Clean Waters Plan

Shown below on the roof, Howard Neukrug is the Water Commissioner at the Philadelphia Water Department and the man behind the Green City, Clean Waters Plan:

The PECO green roof is under management with the  Pennsylvania Horticultural Society (PHS) which leads regular tours of the roof by appointment and on special  occasions.

“In order to safely accommodate guests, the roof area used for tours and gatherings is separated from the rest of the expanse by a self-ballasting, ADA compliant railing for pedestrian safety. The railing provides a secure barrier without requiring the attachment to the roof deck or penetration of the waterproofing membrane.” ~  Roofmeadow Case Study

The  43,000 square foot  extensive portion is unirrigated and was planted with drought resistant vegetation using 12 different species of Sedums.  The remaining  2,000 square foot  intensive portion is planted with perennials and ornamental grasses indigenous to Pennsylvania  and uses a partial base capillary irrigation system, providing moisture without losing any water into the atmosphere.

Due to weight concerns, the growing media is a specially formulated lightweight blend specified by Charlie Miller and the pre-vegetated mats were produced with the same blend by Sempergreen.  On site in Philadelphia, a second batch of extra lightweight media was distributed before the mats were unrolled. The growing and drainage media for the extensive areas and the intensive beds and planters were provided by SkyGarden.

“We made a very definite decision to choose plants that were drought resistant or drought tolerant.” ~ Liz Williamson of PECO in 6abc.com.

The green roof has recovered from die back of some species during the hot, dry summer of 2010; the vegetative cover is now more diverse and vigorous than ever.  The Roofmeadow maintenance program is being followed and documented.

“Roofmeadow and PHS closely track the native plants to identify those that are best able to endure the harsh conditions of a windy, riverside rooftop.”  ~  Roofmeadow Case Study.  Download it here.

Along  with the City of Philadelphia, the PHS is co-hosting the upcoming 9th annual  Green Roofs for Healthy Cities 2011 CitiesAlive Green Roof & Wall Conference on November 30 – December 3 (read more about the Conference here).

Drew Beecher, president of PHS, and Philadelphia Mayor Michael Nutter were filmed for  this promotional video below  on top of the PECO greenroof – click to see:

The PECO  Main Office Building  greenroof will be included as part of the  CitiesAlive  Center Cities Tour and also will be the focus of a technical session, Session 5.  If you come to Philly for the CitiesAlive Conference, you must see this wonderful roof!  Aramis and I will definitely be on this tour.

Public outreach and education are very important to PECO – if you can’t make it for CitiesAlive, do call PECO when in town to set up a tour.  The PECO Main Office Building is located at 2301 Market Street, Philadelphia, PA 19103  – visit their website here.

Thursday, October 6:  OF05 – Enacting a Green Roof by Law –  Nathan Phillips Square Toronto City Hall Podium Green Roof

Don’t miss out on the opportunity to Tour the award-winning 37,000 sf  LiveRoof Green Roof Installation at Toronto City Hall.  Featured in an off-site educational session at Greenbuild, the guided tour is part of “OF05 – Enacting a Green Roof by Law” and will be held on Thursday, October 6, 2011, 3:00-5:30 p.m.

“The 37,000-square-foot podium green roof at Toronto City Hall is the largest publically accessible extensive green roof in all of Canada.  This LiveRoof project stands out as a prominent element in the revitalization of Nathan Phillips Square. It has won several awards, including a 2011 Regional Honour Award from the Canadian Society of Landscape Architects.” ~ Dave MacKenzie, horticulturalist and president, LiveRoof, LLC.

And, Terry McGlade, environmental business development representative at Flynn Canada Ltd, the company that installed and project managed the overall green roof contract for Toronto City  Hall says:

“Toronto is the first North American city to require new developments to include green roofs. Greenbuild will offer an educational session devoted to the development, implementation, results, and future of Toronto’s pioneering initiative. The guided tour of the City Hall green roof is sure to be a highlight of this off-site session.”

Friday, October 7: HD13 Green Roofs for Healthy Cities – Greenroof and Wall Tour

“The green roofs and walls on this tour provide excellent examples of integrated design that improve the quality of life for inhabitants of the building and for the surrounding community. One of the more important features of a green roof or wall is its ability to enhance other sustainable features. From providing food and biodiversity in an urban setting, to enhancing a building’s air quality and improving on-site sustainable energy production, green roofs and walls provide dynamic and aesthetically pleasing components to green buildings. These projects are all uniquely Canadian through their location (both interior and exterior) and a hardy plant selection, as well as their functions and required maintenance through the various seasons of Toronto.” ~ Greenbuild
