Today we have the pleasure to air Dr. Nigel Dunnett’s video presentation “Sky Meadows – Integrating People and Nature: Sustainable Green Roofs and Roof Gardens” from our Greenroofs & Walls of the World™ Virtual Summit on greenroofs.tv and our GreenroofsTV channel on YouTube.

Aramis and I have known Nigel for a while now, probably about nine years or so – he is quite a gentle yet very enthusiastic and passionate soul when it comes to greenroofs and living walls!  We run into him all over the place at conferences worldwide: Nuertingen, Boston, Basel, London, Singapore… and with his years of study and knowledge, we were so happy he agreed to participate in our Virtual Summit!

Research on greenroofs has been under way by the Department of Landscape at the University of Sheffield investigating the range of plant material that is suitable for use on extensive and semi-extensive greenroofs in the UK climate since 2003.  Further trials investigate plant establishment methods, particularly the use of seed mixtures to establish meadow-like communities of both native and non-native grasses and flowering plants:

Nigel Dunnett, PhD is Director of the Green Roof Centre and Professor in Planting Design and Urban Horticulture at the University of Sheffield, UK.  With a background and experience in botany, ecology, horticulture and design, his teaching and research focuses on sustainable urban planting approaches to maximise benefit to people and wildlife.  He is lead author of Planting Green Roofs and Living Walls, 2nd edn 2008; Small Green Roofs: Low-Tech Options for Greener Living, 2011; and Rain Gardens, 2007. He convened the First and Second National Green Roof Conferences in the UK, and acts widely as a consultant on urban planting design matters.  He devised the vegetation strategy for the green roof on the Sharrow School, UK – the world’s first purpose-designed and government-designated green roof nature preserve, and is currently horticultural consultant to the London 2012 Olympic Park.

Dr. Nigel Dunnett’s “Sky Meadows – Integrating People and Nature: Sustainable Green Roofs and Roof Gardens” presentation proposes that green roofs represent a unique opportunity for inserting large areas of diverse, naturalistic, biodiversity-supporting, and beautiful vegetation into the heart of our urban areas: an opportunity that is virtually impossible to repeat in the same way on the ground.

Sustainable solutions now exist for all contexts: large and small, public, private, intensive through to extensive.  Drawing upon the dramatic potential of dryland vegetation around the world, and his own research and practice, the author looks again at the ethical and aesthetic considerations for creating green roofs that are exciting for people, beneficial for wildlife, and low in resource-use.

Greenroofs.com Project of the Week: 1/2/12
Delft University of Technology Library
Delft, The Netherlands
16,146 sf. Greenroof

Year: 2009
Owner: ING Vastgoed
Location: Delft, The Netherlands
Building Type: Educational
Type: Intensive
System: Single Source Provider
Size: 16,146 sq. ft.
Slope: 15%
Access: Accessible, Open to Public

Project Description & Details

Constructed in 1960s, Delft University originally built their intensive greenroof in 1997. Meant for recreation over the library, in 2009 the greenroof was renovated. The 15,000 m² library contains extensive underground book archives, reading rooms, the university publisher, offices, Trésor for historical books and exhibitions, study spaces, and a book binder and book shop. It won the National Steel Award 1998 and Corus Construction Award 2000. Enjoyed throughout the year, the greenroof is converted into a sledding hill in the winter.

Mecanoo Architecten designed the library as a sloped plane, extending the grass from the ground to the very edge of the roof: “With a grass-covered roof, high-performance glazed facades and subterranean storage for heating and cooling, the building reaches high standards of sustainability.” With the 2009 roof renovation, the existing leaking single ply roofing was removed and replaced by a fully adhered two layered roofing system on a cellular glass insulation. ZinCo Elastodrain gives protection for the roofing system; the lightweight 6 inch deep substrate and lawn complete the ZinCo green roof build-up.

The Delft University of Technology Library greenroof is featured in The 2012 Greenroofs & Walls of the World™ 12 Month Wall Calendar in the month of September.

Designers/Manufacturers of Record

Founded in 1842, Delft University of Technology is the oldest, largest, and most comprehensive technical university in the Netherlands.  With eight faculties and numerous research institutes, the “Technische Universiteit Delft” in Dutch or TU Delft for short, covers four focus areas: energy, mobility & infrastructures, health and environment.

Constructed in 1997, Delft-based Mecanoo Architects designed the striking and airy Delft University of Technology Library as a contrast (yet complement) to the Aula or General Assembly Hall, built in 1966 by architects Van Den Broek & Bakema, softening this imposing Brutalist structure that sits across the way.

The photo below by Francine Houben is taken from the perspective of the library greenroof flowing down towards the hulky Aula, demonstrating its relationship with the adjacent landscape:

The central library appears to rise out of the earth, covered with soft grass for all sorts of recreation and pierced by its iconic steel cone.

The cone is more than an architectural statement – it’s topped by a massive skylight that not only provides lighting to the interior but it also helps highlight the cone from the interior.  The building consists of five levels, four of which are contained in the conical volume.

A suspended gallery of books against cobalt blue walls runs right through all four levels.

And floor to ceiling glass panes allow daylighting to stream in throughout the multi-level space:

Who better than the architects than to describe the project?  Read on from Mecanoo:

“symbiosis

In designing a large new university library, various references come to the fore. Famous libraries, ranging from the old Bibliothèque Nationale in Paris (1875) by Henri Labrouste to the Stockholm Municipal Library (1927) by Erik Gunnar Asplund, have called for an advanced contemporary building. Today such a building must be a gateway to the digital highway but must also refer to important traditions, including access to knowledge and the rarefied atmosphere of study within a splendid environment. In the case of Delft, with a thousand workstations and facilities to accommodate three thousand students each day, the building must also be the heart of the university and provide a landmark within a campus the size of a small town. The design must also consider its relationship with the centrally placed auditorium, the brutalist building by Van den Broek and Bakema, great names in the history of the university and Dutch architecture. Through contrast, a symbiosis has been established – the towering concrete of the auditorium and the landscape in which the library is sited form a new unity.

pushpin

The large lawn roof is tilted up at one corner like a sheet of paper held by a single point. The hollow beneath houses the library. A cone, the symbol of technology, pierces the library and the landscape, affixing them like a pushpin. With a grass-covered roof, high-performance glazed facades and subterranean storage for heating and cooling, the building reaches high standards of sustainability. The entrance affords a glimpse of the sunken book stacks for rare and irreplaceable books. Inside the towering suspended bookcase for the less fragile books astonishes the visitor. The deep blue background gives the wall-to-wall racks the feel of a theatre set. The columns in the central hall are not only structural but also provide lighting and heating. The sloping metal ceiling continues without interruption across all spaces above a floor the colour of Saharan sand.

perspective

A library must provide an environment that enables concentration through silence, comfortable furniture and pleasant lighting. Daylight penetrates the building not only through the climate-control glazing in the facade but also through the cone that pierces to the heart of the building. The cone also gives form to a variety of study rooms. The space that adjoins the central hall contains long tables with three hundred workstations with partitions in a shifting perspective indebted to Labrouste.” ~ Mecanoo TU Delft profile

The TU Delft Library provides guided tours for groups of users and associates of the library in either Dutch or English which are arranged by appointment; to apply, contact customer service at Ask Your Library.  Their website says that groups of architects, and I would imagine other design professionals, can be given a guided tour by the architectural firm Mecanoo, focusing on the construction and design of this light, spacious, and unique building.

Now that the Delft University of Technology Library greenroof has been completely renovated with a ZinCo system, it can be enjoyed for decades to come.  Here’s a truly ecologically designed library that can be used throughout the seasons, both inside and out.  How many libraries can claim that?

The spectacular 8 House by BIG Architects in the outskirts of Copenhagen is once again in the news, this time being honored by the American Institute of Architects (AIA) with the 2012 AIA Institute Honor Award for Architecture.

Through their awards program, the AIA has a long tradition of recognizing individuals and organizations for their outstanding achievements in support of the profession of architecture and the professional organization.

“The Institute Honor Awards program recognizes achievements for a broad range of architectural activity to elevate the general quality of architecture practice, establish a standard of excellence against which all architects can measure performance, and inform the public of the breadth and value of architecture practice.” ~ AIA

We’re big fans of BIG Architects – sorry, couldn’t help it – which is very easy since every project they produce is not only fresh and out-of-the box but a shining example of ecological, site-specific and community-specific design.

“The 8 House masterfully recreates the horizontal social connectivity and interaction of the streets of a village neighborhood through a series of delightful accessible ramps in a mixed use, multifamily housing project. The skillful shaping of the mass of the facility provides an invigorating sculptural form while creating the ramped “pedestrian” street system and providing full depth dwelling units which are filled with light and views.

People really ‘live” in this newly created neighborhood with shopping, restaurants, an art gallery, office facilities, childcare, educational facilities and the sound of children playing. This is a complex and exemplary project of a new typology.” ~ 2012 Institute Honor Awards for Architecture Jury Comments

See all of the other eight 2012 AIA Awards Recipients here.

You’ll find three different types of residential housing and 110,000 ft² of retail and offices here, in the shape of a multi-level bow tie.  And this mixed-use building comprises Denmark’s largest private development ever undertaken.

Plus, a building designed to allow its residents to bike all the way from the street up to its 10th level penthouses is pretty cool, but add a huge V-shaped sloping greenroof to it, and you’ve really got a spectacular structure!

“Having established ourselves in New York City this past year we are honored that the AIA has given this great distinction to the 8 House which is a further realized example of our approach called architectural alchemy – the idea that by mixing traditional ingredients, retail, row-houses and apartments in untraditional ways – you create added value if not gold. Housing projects are rarely brought out as world architecture. The fact that the 8 House has now achieved this honorable status, can be seen as a symbol of a piece of architectural alchemy that works. Moreover, I am genuinely happy that our long and inspiring cooperation with Per Høpfner and St. Frederikslund is rewarded in the other parts of the world.” ~ Bjarke Ingels, Founder & Partner, BIG in the January 9, 2012 Press Release

I wrote about 8 House or 8 Tallet last September, 2011 when we featured it as our Greenroof of the Week, or GPW – read all about it here where you can see all the stunning photography of the site and interiors, and see the profile in The Greenroof & Greenwall Projects Database.

And it’s no wonder that Haven Kiers and I selected the unique 8 House for our 2011 Top 10 List of Hot Trends in Greenroof & Greenwall Design in the #10 category, “Client Specific ‘Boutique’ Greenroofs.”  (See our video for the Greenroofs & Walls of the World™ Virtual Summit 2011 on our GreenroofsTV YouTube Channel here.)

Inspirational 8 House is “architectural alchemy” indeed!  Congratulations to BIG and everyone else who worked on this beautiful and highly functional project!

Following a recent survey to its member companies, the FBB (German Professional Green Roof Association) estimates that around 8 million m² new green roofs are installed in Germany every year.  The companies surveyed include manufacturers and planners, merchants and operators, 100 of which are member companies united under the association.

In 2008, extensive green roofs carried about 88% of the green roof market, with intensive green roofs filling in the remaining 12%.

Since then, intensive green roofs have been gaining popularity, with 17% in 2010.  The FBB states that building owners appreciate the benefits of additional amenity spaces. FBB members believe this trend will continue as increasing numbers of underground parking garages receive roof gardens.

“FBB was founded as an open forum for manufacturers and planners, merchants and operators in 1990. The organisation was born from the then-visionary idea of understanding the relationship between nature and constructions not as oppositional, but as an opportunity. Both the green roofing and conventional roofing industries are equally represented.” ~ FBB.de

As I promised at our presentation at CitiesAlive in Philadelphia a couple of weeks ago, today we are airing Haven Kiers‘ and my “2011 Top 10 List of Hot Trends in Greenroof & Greenwall Design“ from our Greenroofs & Walls of the World™ Virtual Summit on greenroofs.tv and our GreenroofsTV channel on YouTube.

“This is our fifth anniversary of the “Top 10 List” and an amazing amount of development has occurred over the past five years in the vegetative roofing industry.  Projects that were once scoffed at and considered impossible to get built are popping up all over the globe, and greenroofs are no longer considered fringe architecture, destined to be the first sacrifice to value engineering.

“To honor the new ubiquity of architectural greening, this year our Top 10 will focus on greenroofs at all different scales, from micro to macro.

“As “vegitecture” increasingly becomes a mainstay of both sustainable and cutting edge design, the list of greenroof and greenwall trends continues to expand.

This year we’re showcasing greening at both the micro and the macro scale, from small scale DIY greenroof projects to towering skyscrapers stacked with fruit and vegetable crops, parks, and energy facilities atop sky gardens, walls and bridges.” ~ Haven Kiers and Linda Velazquez

I have to say that Haven and I had a blast putting this together, and especially filming it together!  She flew to Atlanta last September just for the occasion, and I think you’ll really get a feel for our enthusiasm.

And, since we didn’t have any time restrictions like we normally do at all the conferences – where we have to speed through our project selections – here we took our time a bit more and, as a result, feature quite a few more projects that you would normally see.

Enjoy!  Visit greenroofs.tv to see the “2011 Top 10 List of Hot Trends in Greenroof & Greenwall Design” or click below.

We’ll be working over the next few weeks to add most of the projects here to the Greenroof & Greenwall Projects Database so you can learn more about each.  We appreciate your feedback, and welcome your thoughts on the new and newsworthy projects for our 2012 Top 10 Hot List!  Feel free to contact Haven me directly at DesignEditor@greenroofs.com and me at Linda@greenroofs.com.

Didn’t get to see the Opening Keynote Address video by Charlie Miller yet which we featured last week?  No problem – watch it after the Top 10 on the exclusive Virtual Summit greenroofs.tv play list.  Check back next week on GreenroofsTV for our third installment from the Greenroofs & Walls of the World™ Virtual Summit 2011!

Greenroofs.com Project of the Week: 9/12/11
World Expo Zaragoza 2008/Zentro Expo Zaragoza 
Zaragoza, Spain
765,000 sf. Greenroof

Year: 2008
Owner: Expo Zaragoza Empresarial, previously Expoagua Zaragoza 2008 S.A.
Location: Zaragoza, Spain
Building Type: Commercial
Type: Intensive
System: Single Source Provider
Size: 765,000 sq.ft.
Slope: 1-5%
Access: Accessible, Open to Public

Project Description & Details

The theme of the World Expo Zaragoza 2008 was “Water and Sustainable Development” and architects and designers from around the world were called to build forward-thinking structures for the 57-acre site. Massive greenroof areas covering the 765,000 square feet of the elevated structures also included photovoltaics.

Only 11.172 sq meters out of the total surface were viable for pedestrian use due to structural requirements and building time restrictions, so a ZinCo system with a 25 cm thick light substrate growing medium was used. The 754,000 sf “Pabellones de las Naciones,” or Pavilions of the Nations, displays various types of water distribution found in nature as you meander through lush landscaped areas of pathways, seating areas and a constructed river. The 11,000 sf roof of “Aguas Compartidas,” or Shared Water Pavilion No. 6, has varying slopes up to 18 degrees. Its design intent was to show the potential for fair distribution of water across the region; rainwater was collected and used for irrigation of the beautiful perennial gardens.

Additional Info

Located on the banks of the Ebro River, careful site design and sensitive construction practices were essential to maintaining its essential physical, social and environmental characteristics .

In reference to selecting an appropriate greenroof system to cover the huge expanse, and do so beautifully and well, Carlos Avila Calzada, Head of the Landscape Department for the Expo Zaragoza 2008 said:

“Regarding the green roof structure it was decided to choose a ZinCo system with a 25 cm thick topsoil layer, formed by a light substrate. When designing the green roof we set three main objectives: choosing a design that would provide a global idea of all the pavilions’ roofs, creating a green structure which would show a vivid contrast between a neutral background and large colourful areas and incorporating the photovoltaic panels in the design. The walking area has different characteristics as there are wooden paths and spaces for the visitors to sit down and enjoy the view over the exhibition site or the rest of the city. These areas, equipped with furniture and lighting, resemble those of public use in cities more than a green roof.”

105 countries were represented here with an extensive cultural program. Concentrated on the future of water, the event ran for 93 day and experienced long waits for many of the pavilions, but despite that visitor numbers were lower than forecast at 5.5 million instead of 6.5 million.

King Juan Carlos and Queen Sofia attended the closing ceremony, and according to TypicallySpanish.com, the King said such events “encouraged us to take on new projects together, and served to unite and build an always better Spain.”  Spain commissioned a special stamp commemorating the Expo:

Once concluded on September 14, 2008, the World Expo Zaragoza 2008 was redeveloped and revitalized by new owners Expo Zaragoza Empresarial and renamed Zentro Expo Zaragoza – the new activity, entertainment, and economic center for the city – and opened again to the public on January 20, 2011.

Dismantling of the pavilions and thematic spaces resulted in the creation of the state-owned (Government of Aragon) Ebro River park.  The mission states that they are “socially and environmentally committed to the future challenges of Zaragoza.”

“El meandro de Ranillas” is the largest open area with natural greenspace for the people of Zaragoza and its surroundings.  More than 120 acres of recreated nature and outdoor activities now include the Water Park -120 acres of nature and outdoor activities with a whitewater channel and the first artificial beaches in Spain - and a variety of commercial and service facilities.  The “Ranillas Meander” is a space that attracts audiences of all ages and is very family oriented.

This complex of over 77,000 m2 of offices creates a unique environment of office space called Dinamiza (Boost) Business Park.  And Fluvia is an exclusive enclave of only 18 commercial stores offered here with more than 19,000 m2 of space.  An estimated 1,500 visitors each day are offered a wide variety of entertainment options including cinemas, shops, a gym, over 15 restaurants, bars and cafes with outdoor terraces – all overlooking the river Ebro.

Also present on site of the former World Expo Zaragoza 2008 is the new Institute of Climate Change which intends to be a unique platform for the meeting of the Spanish scientific community and international participants to implement innovative and cutting edge research on a global level, making Zaragoza a role model for their commitment to the environment:

To all accounts, the greenroofs have fared well and will, no doubt, continue to provide a lovely cooling respite to inhabitants of Zaragoza and international visitors alike.
