Video & Project of the Week for September 7, 2015: Regis High School in New York City

September 10, 2015 at 9:08 am Project of the Week: 9/07/15


Regis High School
New York, NY, USA
22,000 sf. Greenroof


Project Description & Details

Founded in 1914, Regis High School is a five-story landmark private Jesuit university-preparatory school located on the Upper East Side of Manhattan. In 2010 the school completed its ambitious Green Roof Project, with the installation of nearly 25,000 square feet of an extensive green roof by Greensulate on its upper roofs. The roof top project, which includes a 20kW solar panel array, also houses a classroom, two beehives, scientific monitoring equipment with Columbia University, a weather station, and an astronomy observation area. A network of paths and platforms connect the stations, making the space easy to navigate. A physical classroom on the roof itself houses scientific monitoring equipment, along with the school’s telescope and other classroom materials. The size and design of the roof was groundbreaking, as it was the 2nd largest green roof in the city when it was completed, and is currently the 5th largest green roof in Manhattan.

The green roof uses a mix of sedum mix, native grasses, native perennials, and wildflowers across the multi-level space to create a natural, outdoor feel amidst New York City’s urban backdrop. The system does not require irrigation, and continues to be healthy and thriving five years after the initial installation. Concrete pavers were installed adjacent to the 20 kW solar panel array to create space for an outdoor classroom for up to 15 students and a teacher. An herb garden is planted to provide chives, mint, oregano, lavender, sage, and more for the school cafeteria, and Trex decking pathways provide easy access throughout the roof. The raised HVAC system benefits from the cooling effect of the green roof, as do the solar panels, which are estimated to be 10-15% more efficient.

NOTE: Greensulate will be providing a live tour of the Regis High School green roof on Thursday, October 8th, during the 13th Annual Cities Alive Green Roof & Wall Conference in New York City. Greensulate will be shuttling groups over from the convention space, and space is limited.

Video & Project of the Week for August 3, 2015: LeFrak Center at Lakeside – Prospect Park

August 5, 2015 at 2:21 pm Project of the Week: 8/03/15


LeFrak Center at Lakeside – Prospect Park
Brooklyn, NY, USA
44,329 sf. Greenroofs


Project Description & Details

In the nineteenth century, Frederick Law Olmstead and Calvert Vaux designed the 585-acre Prospect Park, one of Brooklyn’s most treasured destinations for relaxation and recreation and a national landmark. Designed by noted architects Tod Williams and Billie Tsien, in collaboration with the Alliance’s acclaimed landscape architect Christian Zimmerman, the 75,000 sf LEED Gold certified Samuel J. and Ethel LeFrak Center at Lakeside provides seasonal ice skating, roller skating, biking, boating, and water play. Designed by Roofmeadow, the recreation facility boasts a 24,601 sf extensive green roof and a 19,728 sf intensive green roof, and has earned the 2015 AIA Institute of Honor Award for Architecture.

A 23-foot high canopy on the LeFrak Center supports the extensive sedum green roof from Moerings USA / Sempergreen® above and a whirlwind of activity below including ice skating in the winter and roller skating in the warm seasons. The concession buildings are buried in the land and covered by the landscape on structure green roofs which connect to each other, the existing pathways, and the highly variable landscape grades, allowing the structures to blend into the park landscape. The intensive green roof footpaths approaching from the east and north ascend gradually and imperceptibly over the top of the 20,000 square-foot complex, eventually ending at an overlook of the facility and the scenic Prospect Park Lake beyond. An innovative stormwater collection strategy and 15,000 gallon rainwater retention cistern result in zero rainwater runoff from the intensive green roof areas, with no potable water used to irrigate the green roofs. The combined green roofs prevent over 900,000 gallons of rainwater from entering the sewer each year, and this eight-acre redevelopment project is a national model for integrating cutting edge sustainable design into a historic park.

Now Playing at the Virtual Summit 2015: “From Passive House to the Cold North—How Vegetative Envelope Components Impact Buildings” Panel with Dr. Bob Cameron, Dr. Allen Lee, Dr. Karen Liu, and Chris Wark

May 1, 2015 at 5:12 pm

In celebration of honoring Earth Day 2015 and our planet’s ecology through healthy, regenerative design, we are highlighting each of the 23 awesome videos from our 30+ spectacular speakers from‘s Greenroofs & Walls of the World Virtual Summit 2015 ~ Connecting the Planet with Living Architecture: People, Projects & Design, running through May 31st.


Our hope is that by familiarizing you more with each presentation and its particular benefits, you will be enticed to join us during our wonderfully easy-to-navigate online Virtual Summit!  And, along with the speakers’ input, I will identify 5 Key Learning Objectives or “takeaway” bullet points that each video presentation provides to participants.

VS2015-CameronLeeLiuWarkToday we are spotlighting the panel presentation “From Passive House to the Cold North—How Vegetative Envelope Components Impact Buildings” with Dr. Bob Cameron of Penn State University in University Park, PA, Dr. Allen Lee of Cadmus in Portland, OR, Dr. Karen Liu of Xeroflor Canada in Toronto, Canada, and Chris Wark of BuroHappold Engineering in New York City.

VS2015-How VegetativeEnvelopeComponentsImpactBuildings4

Amy Chomowicz, the Program Administrator for the Sustainable Stormwater Management Division and the Ecoroof Program with the City of Portland Environmental Services, came up with this idea for the panel several months ago, intended to spotlight greenroofs and walls and their energy implications.  Once she realized that prior work commitments wouldn’t allow her to participate, she continued to help organize it and invited Allen Lee, PhD to moderate instead, whom we didn’t know prior, but he was great – thank you, Amy and Allen!

VS2015-How VegetativeEnvelopeComponentsImpactBuildings3

We missed Amy but the panel did an awesome job!  By the way, you can hear from Amy and her colleagues from BES in their presentation from our inaugural Virtual Summit 2011 in “The Portland Ecoroof Program” A Cross-section of the Green Roof Movement in Portland, Oregon, USA.”

VS2015-How VegetativeEnvelopeComponentsImpactBuildings2

We have been familiar with Dr. Karen Liu’s research work for years now, and see her often at conferences around the world (look for an upcoming Guest Feature article coming from her soon!)  And we’ve known the wonderful Bob Cameron for a good many years now from his work at Penn State, and we were fortunate to spend a good deal of time with him on our 6-day tour of China in 2012 after we both spoke at the awesome Hangzhou World Green Roof Conference 2012.  Look for his accompanying research article “An Integrated Biofilter System to Contribute to Net Zero Architecture while Providing Decentralized Wastewater Treatment” soon on

Also, don’t miss Bob’s second presentation here at the Virtual Summit 2015 titled “Versatile Living Walls & Roofs: International Applications for Agriculture, Energy Conservation, Pollution Attenuation, and Aesthetics.” And, he also participated at our Virtual Summit 2013 on the Panel Session “Theory & Field Studies: An Interview with Dr. Ian Balcom from Lyndon State College of Vermont & Dr. Robert Cameron from Penn State – Phytoremediation Chapter Two” with Patrick Carey.


Chris Wark has been a contributing editor, aptly enough the Energy Editor, with since 2011, and he and his wife Wendy, have been good friends of ours since 2004.  In 2011 he completed a 32-page, 7-part Green Roof Energy Series (PDF, 2011) which is a great backgrounder for this discussion!  Chris also participated in our inaugural Virtual Summit 2011 – watch his video “E = MC2 of Green Roofs” on our YouTube channel.

University Park, PA, USA. “Robert “Bob” D. Cameron, PhD spent more than two decades directing the global environmental programs of a Fortune 30 multi-national conglomerate. In the late ‘70s in collaboration with NASA, he designed, permitted, and constructed the first constructed wetlands to treat wastewater from the natural gas industry. Working on every continent except Antarctica, Bob designed award winning environmental programs based on sustainability concepts. Later as President of his own corporation, he de-engineered historic buildings destined for the wrecking ball, which he then relocated and reconstructed with green architectural features.

Pursuing a life-long goal, he recently earned his doctorate from Penn State University (PSU) at the Center for Green Roof Research. His thesis entailed the invention and construction of a functional architectural system to attenuate wastewater pollutants while reducing a building’s energy use and providing a platform for urban agriculture. Currently, Bob has an appointment with the Department of Landscape Architecture at Penn State University and teaches collegiate courses and conducts research on greenroofs, livings walls, constructed wetlands, aquaponics, and artificial islands while also managing Eco Applied Technologies, a consulting firm for commercial, residential, and industrial applications.” Read his complete bio here from the VS2015.

You will benefit from these 5 Key Learning Objectives as Dr. Bob Cameron, Dr. Allen Lee, Dr. Karen Liu, and Chris Wark share on the subject:

1) Focus on key impacts and economics of greenroof and greenwall vegetative envelope components including energy and stormwater.  Identify what they are, how you can predict outcomes, what prediction tools are out there; a look at using greenroof and greenwall crops with biofilters in PA, others greenroof gardens in NYC, Portland, and China where rooftop farming is becoming very popular;

2) How does nature work, from an energy standpoint, using biology in regards to greenroofs and walls?  Integrating green building components relative to factors of energy – what kind of media, locations, building geometry, orientation, should people be looking at, i.e. optimizing greenroof to greenwall ratio. What ideas does everyone have for incorporating living green components into buildings?  The growth of pvs and greenroofs are discussed; 

3) Bob: His multi-year study at the PSU Green Roof Center concentrated on biowalls and greenroofs as a water resource and how these systems could be used to not only clean but also reduce the energy need and concurrently grow crops.  Get detailed results on how he achieved EPA’s cleanliness standards in less than 24 hours and at the same time reduced both the exterior and interior temperatures of the buildings; 

4) Karen: Started in 2000 with the National Resource Council in Ottawa performing multiple tests on various sites in Toronto and Vancouver, BC concentrating on temperature variances between winter and summer on greenroofs and growing media depth differences on water retention and energy savings;

5) Chris: Discussion on performance building concepts of the 90’s PassiveHaus movement originating in Dusseldorf, Germany and Net Zero Buildings, how to minimize the amount of energy generated within a small building through correct design and material components and evaluation of lifestyle issues and aesthetics.  Green building industry has grown so much in the last 20 years and PassivHaus has matured along the way – can we be doing more? Greenroofs are a promising part of it.
