Project of the Week Levi's Stadium

Project Description & Details

Hosting the Super Bowl 50 on February 7, 2016, Levi’s® Stadium is a $1.27 billion multi-purpose facility with the flexibility to host a wide range of events with seating for about 68,500 people, featuring 176 luxury suites and 9,000 club seats. Fans attending San Francisco 49ers home games experience football in the most eco-friendly and sustainable LEED Gold certified facility in the league. State of the art technology is used throughout the stadium, and visitors may view a live dashboard display featuring current energy measurements, water and air monitors, and other dynamic green features as the building operates daily. Designed by HNTB, the iconic feature of the stadium is the massive 5-story Suite Tower on the west side, topped by the NRG Solar Terrace green roof.

Project of the Week Levi's Stadium

The installation of 1,186 solar panels on the canopy framework on the green roof and on three solar pedestrian bridges connecting the parking lot to the park generate 375 kW of power at Levi’s Stadium – as much renewable energy as it will consume on game days. And the NRG Solar Terrace green roof is an inviting space which can be booked for receptions and ceremonies. The 27,000 square foot American Hydrotech green roof contains 16 species of vegetation native to the Bay area for the concessionaires, who will utilize produce within local farm-to-table menus. 85 percent of the water used at the stadium is recycled, used for both potable and non-potable uses such as the playing field irrigation water.

Project Description & Details

An ambitious and highly acclaimed urban reclamation project created in three phases over a period of eight years, the award-winning High Line is noted for its innovative design and sustainability. Located in New York City’s Meatpacking District and Chelsea neighborhood of Manhattan, the length of the High Line traverses 23 uninterrupted city blocks, 30 feet in the air, with expansive views of New York City and the Hudson River. At a total of 1.45 miles the High Line is considered the “longest greenroof” in the world to date.

The former abandoned elevated railway was championed by the non-profit group “Friends of the High Line” and designed by the landscape architecture firm of James Corner Field Operations and architects Diller Scofidio + Renfro with planting design from Piet Oudolf and engineering design by Buro Happold. ZinCo USA provided the technical basis for all the green roof design concepts in terms of plants, walkways, and leisure areas with Floradrain® drainage elements and ZinCoblend M growing medium.

Green Roofs for Healthy Cities Challenges New York to Become Number #1 for Green Roofs and Walls in North America

October 1, 2015 at 1:43 pm

Have you seen this challenge from Green Roofs for Healthy Cities yet?  Sounds like they’re throwing down the gauntlet for the City of New York to step up their greening efforts!

New York is already a city with many, many living architecture projects – in fact, we highlighted this fantastic metropolis in our 2014 Top 10 List of Hot Trends in Greenroof & Greenwall Design in the #3 category: The Green Apple: New York City

But GRHC believes the city that never sleeps can do better!  Read on from their recent News Release:

Building 3 Million square feet of Green Roofs in New York yields over $95 million in public benefits over a 25 year period including over 4,000 new jobs in construction and maintenance!

New York, NY – Tuesday September 29, 2015 – With just one week to go before 2015 CitiesAlive Green Roof and Wall Conference Oct. 5-8, 2015 in Brooklyn, Green Roofs for Healthy Cities (GRHC), the green roof and wall industry association issued a challenge to New York today, calling upon them to work together to implement more than 3 million square feet of green roof each year starting in 2016.

“New York City is in fifth place for the number of green roofs installed after much smaller cities like Washington, Chicago and Philadelphia. We are issuing a challenge to New York policy makers, developers, designers and building owners to contribute to the goal of 1 billion square feet of green roofs installed in North America by 2022 – that amounts to just over 3 million square feet installed each year!” said Steven W. Peck, GRP, Founder and President of Green Roofs for Healthy Cities.

“New York has incredible potential to improve the quality of life in the city by utilizing the miles and miles of rooftops to provide amenity spaces to recreate, grow food and get in touch with nature,” said Mark Morrison, CitiesAlive Conference Co-Chair and Principal, MKM Landscape Architects. “With the right types of policies in place, many building owners would leap at the opportunity to turn their barren rooftops and walls into a private or public oasis,” he added.

While important progress has been made in New York, there is considerable room to utilize green roofs and walls to fight climate change, create jobs and improve equity and social justice across the Five Boroughs. For example, industry leaders in New York have been calling on local and state policy makers to:

  • double the $5.23 per square foot tax abatement for green roofs,
  • remove bureaucratic barriers to implementation,
  • expand the existing Department of Environment’s Green Infrastructure Grant Program,
  • change the City’s stormwater detention standard to a retention standard, and
  • make changes to the building code so all new buildings have the loading capacity for green roof installations.

“We are at a critical juncture as a city, with rents increasing faster than wages; environmental catastrophes such as floods threatening the city’s livelihood; high rates of asthma, obesity and hunger; and increasing divisions between the haves and have-nots. The benefits of green infrastructure to New York City are well documented: green infrastructure reduces energy demand, mitigates flooding, improves housing quality, air quality and public health and supports urban agriculture. For New Yorkers, the choice is ours whether we embrace green infrastructure as a critical solution to our environmental and societal challenges, or whether this technology remains underutilized,” said Rob Crauderueff, Co-Chair of CitiesAlive Legacy Committee and CEO of Crauderueff & Associates.

The Green Infrastructure Design Charrette in Harlem on Thursday, October 8 will bring together local and international designers to help to demonstrate the potential of deep green design and implementation in a 10 block area of central Harlem. The designers will focus on how many jobs can be created, for example, through the use of roofs for food production on buildings owned by the Canaan Baptist Church, a partner in the Charrette.

Perhaps the Big Apple will eventually be known as the Big Green Apple, but regardless, we send kudos to all of the New York City city officials, designers, developers, and researchers who have done so wonderfully so far!

Don’t Miss the London Green and Solar Roof Conference Next Week!

September 24, 2015 at 4:43 pm

The future of roofs is Biosolar!

If you are a proponent of or involved with the fantastic synergy of greenroofs and photovoltaics, then you simply cannot miss the 1st European Biosolar Roof Conference in London next week!  Even better because it’s more comprehensive, the Conference will highlight combining greenroof and solar technologies for biodiversity, renewable energy, and resilient cities.


Supported by the Mayor of London and CIRIA, the one-day event will be held at the London Living Room at City Hall, London, on Monday, September 28, 2015 from 12:00 pm – 5:30 pm.  The cost is only £50, including lunch.

The timing is particularly perfect after all of the media hype over the “new French greenroof law” which is actually still under consideration.


Organizers say the 1st European Biosolar Roof Conference brings together leading speakers to show how combining solar and green roof technologies benefit everyone from inhabitants to investors because they:

• Decarbonise the grid, and create energy resilience by decentralising renewable energy production;
• Provide urban havens for pollinators, now that many cities are more biodiverse than the agrichemical countryside;
• Help cities withstand the impacts of climate change, cooling the city, managing storm water and improving air quality.

Speakers include:

London’s Deputy Mayor for Environment & Energy Matthew Pencharz
COO of the Renewable Energy Association Stuart Pocock
President of the EU Federation of Green Roof Associations Dusty Gedge
Head of Global FM Technical at Standard Chartered Bank Darren Sear
Architect Justin Bere
Gill Perkins of the Bumblebee Conservation Trust
And many others, chaired by sustainable futurist Jim McClelland.

If you haven’t already, you can read more about it from the July 21, 2015 Sky Gardens blog post “London Green and Solar Roof Conference 28th September 2015 (and the French Solar Green Roof Law that Is Not Yet a Law)” by Dusty Gedge President, European Federation of Green Roofs and Walls Associations and  He sits on the EU’s working group for the green Infrastructure and ecosystem services policy.  His work in Europe over the last few years working on a Pan-European green roof course and he is currently advising on a project on green roofs, pollinators, and solar power – Biosolar Roofs.

“Intelligent planning and design should work towards combining green roof and solar technologies – it should not aim towards an ‘either or’ situation. This brings into focus the general thrust of…the Biosolar Roof Project.

The ‘Bio’ element of the Biosolar Roof Project focuses on the provision of biodiversity on green roofs through the use of solar panels.  Solar panels on green roofs can in fact, through good design, provide a more diverse native floral community, which in turn benefits biodiversity, especially pollinators.  This fits neatly into the European Green Infrastructure and Ecosystem Services Strategy that aims to address Europe’s declining biodiversity.” ~ Dusty Gedge on, 2015

Dusty and his colleague Nathalie Baumann spoke on the Biosolar Roofs subject at our 3rd  Greenroofs & Walls of the World Virtual Summit 2015.  Filmed in UK and Switzerland, the presentation celebrates the work of the EU-funded project called Up on the Roof; watch their Biosolar Trailer below:

The London Conference condenses the Biosolar Roof Project’s array of information and stories from across Europe where biosolar roofs are being installed, including in London.  The conference will be of interest to policy makers, building owners, facility managers, architects, landscape architects, ecologists and sustainability professionals – and more.

This is going to be an awesome conference!  We really wish we could have fit it into our travel schedule, but unfortunately we can’t go – this time…Enjoy!
