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.

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.

–   “In the News“

–   Kathy Jentz of the SilverSpringPatch says “Green Roof Keeps United Therapeutics Cool.” Avi Halpert, Vice President of Corporate Real Estate at United Therapeutics called the greenroof their “little oasis” on top of their new headquarters building in downtown Silver Spring, Maryland. Full of flowers, grasses, and lush foliage, the planting beds on the 5th, 6th and 7th floors of the building are full of movement and life. The National Capital Region Chapter of the U.S. Green Building Council selected the United Therapeutics building as the recipient of its 2010 Award of Excellence for new Building Design and Construction. The Schick Goldstein Architect designed project was also awarded LEED Gold. The second building in the United Therapeutics headquarters complex is under construction currently, and will also have a green roof system along with other stormwater mitigation projects including a self-contained street tree box system. Across Spring Street, a playground and area is being designed to include a children’s garden for the new employee daycare.

–   Jessica Tasman-Jones of Auckland Stuff.co.nz talks about how “Support grows for city rooftop garden.” She says that “green-fingered Aucklanders are championing a plan to turn part of an inner-city carpark into a community garden” and the plans are “rapidly gaining support.” According to the Karangahape Garden Facebook page which was set up last week to see what the public interest is like for creating a garden on the upper deck of the carpark, it now has over 1,000 fans. Residents believe Auckland has poor urban planning, especially for residential housing, and people are yearning for a connection to nature that the city is lacking. A community meeting will be held in a few weeks to discuss this “green” idea and you can find the Karangahape Garden Facebook page to be a part of this movement.

GPW: Allen & Overy LLP HQ, Bishops Square

July 17, 2011 at 5:58 pm

Greenroofs.com Project of the Week: 7/11/11
Allen & Overy LLP HQ, Bishops Square
London, England, UK
58,125 sf. Greenroof

Year: 2005
Owner: Allen & Overy
Location: London, England, UK
Building Type: Multi-Use
Type: Extensive & Intensive
System: Single Source Provider
Size: 58,125  sq.ft.  
Slope: 1%
Access: Accessible, Private

Project Description & Details

The new headquarters for Allen &  Overy steps back from Bishops Square in a series of green tiers, with roof gardens overlooking the plaza below. The building was commissioned by Allen & Overy to meet the needs of a modern international law firm with strong environmental objectives in mind, serving both retail and office use. Located in the historically sensitive area of Spitalfields, it completes the regeneration programme of this important neighbourhood bridging the City and the East End.

The headquarters encompasses three landscaped greenroof terraces, and a fourth terrace is covered with photovoltaic cells to capture the power of the sun and reduce the energy take of the building. These open green spaces on private terraces provide an area where staff can relax and also help to reduce urban heating. Alumasc ZinCo green roof components were used as part of the key specifications, including FD 40 Floradrain ® water storage and drainage board as well as specialist substrates which support a large number of grasses, shrubs, and flowering perennials including turf, lavender, heather, iris, sedum, and boxwood.

Designers/Manufacturers of Record

Project Architect: Foster + Partners
Developer: Hammerson Plc, Corporation of London
Planning Authority: Tower Hamlets
Landscape Architect/Sub Consultant: Townshend Landscape Architects
Contractor: Willerby Landscapes
Greenroof Supplier: Alumasc Exterior Building Products
Greenroof System: ZinCo
Waterproofing: Hydrotech Structural Waterproofing


Additional Info

Commencing construction in 2001, the the state-of-the-art building was designed and built specifically for Allen & Overy by leading architects Foster+Partners and  was  finished in 2005.  Their driver for the greenroofs was twofold: they wanted to improve the biodiversity of this highly built up area of London and also wanted to create an outdoor garden type of area for staff to have their lunch, hold meetings and use for client events.

“Bishops Square development provides a major new public space for London larger than the Piazza at Covent Garden. It completes the regeneration programme of this historically important neighbourhood bridging the City and the East End.  Comprising 4 acres of landscaped civic space, a new covered market area, 40,000 sq ft of retail space and 774,000 sq ft of high spec offices, the scheme extends the original wholesale fruit and vegetable market to create a new urban destination with an eclectic mix of offices, residential buildings, shops and a network of pedestrian routes and plazas.” ~  Foster+Partners case study

Foster+Partners also says that the building incorporates the largest commercial photovoltaic installation in Europe and will produce enough energy to power the landscape lighting across the site – I don’t know if this fact still holds true, but it does have a large and rather impressive solar array.  The main roof has about 580m2 photovoltaic cells generating around 50,000kWh per year and the Allen & Overy’s website says the solar array saves 23 tonnes of carbon dioxide.

“We are proud to have been awarded a rating of ‘Very Good’ by the Building Research Establishment Environmental Assessment Method (BREEAM), the world’s leading system for assessing the range of environmental aspects associated with buildings. ” ~  Allen & Overy’s website

The Allen & Overy HQ greenroof  is not only ecologically sensitive, but designed in an elegantly linear fashion.  The private terraces are used often, not only by the employees but also to entertain special gatherings.  Their office brochure states “One of the best features of Bishops Square is the ability to hold barbecues in the summer or evening drinks on the terrace.”

In fact, the  prestigious  offices of Allen & Overy has hosted both the 2010 and 2008 World Green Roof Congresses.  Aramis and I were lucky to have attended the 2008 World Green Roof Congress here put on by Dusty Gedge of Livingroofs.org and CIRIA, with support from the European Federation of Green Buildings, so we can attest to the beauty of the spaces and the hospitality of the greenspace; the views were pretty spectacular, too!  You can read a little about it here.

The open space is extremely inviting: built in benches provide comfortable seating, tall grasses sway gracefully in the wind here and the flowering perennials provide color and structure throughout the seasons.  Granted the bright green grass needs higher maintenance than the other plants, but it does provide nice contrast and the turf is used by many.

The reflective windows of the building present an ever changing London cityscape scenery to visitors – I took this photo in September, 2008 where you can see the iconic Swiss Re Headquarters at 30 St Mary Axe, popularly known as the Gherkin, also designed by Foster+Partners:

The Allen & Overy HQ greenroof offers something that many extensive living roofs unfortunately do not – highly valuable and sought after  amenity  space.  Structural issues aside, it would be awesome if we could have more intensive greenroofs out there to not only provide a cool respite to our animal friends but also to help sooth the human beast in all of us after a long hard day at work!

– Hello, I’m Anjuli Velazquez and welcome to This Week in Review for May 27th, 2011, on    GreenroofsTV.

–  Project of the Week

–   Our project of the week is the Unilever Corporate Headquarters designed by HDR, Inc,  built in 2009 located in Englewood Cliffs, New Jersey.  The greenroof project is a 16,000 sq ft membrane roof retrofit over a 4-story office building, and the existing roofs needed to be replaced because they were leaking and showing signs of deterioration. Unilever desired a roofing system with an enjoyable appearance, considering its high level of visibility from the next door conference room space.  A new “˜Hydrotech‘ monolithic membrane system with an extensive “˜LiveRoof‘ pre-vegetated tray system was used.   A large variety of 15 types of Sedum and one Delosperma was planted.  To learn more about the Unilever Corporate Headquarters greenroof, click on our project of the week photo on our homepage.

–   “In the News“

–  Lorna Thorpe of The Guardian talks about “British Land – offering urban shelter and habitats for insects and rare birds.” She says, “British Land won over the judges for its contribution to local biodiversity – urban habitats that provide shelter and foraging for insects, rare birds and plants in the heart of London.”     In one of the most effective ways to enhance biodiversity, British Land is setting the standard for biodiverse green roofs at many of its buildings; and over the past few years they have installed green roofs on all of its most recent office developments in central London, along with retrofitting them to some existing buildings.

–   Andrew Michler of Inhabitat.com says that “Green-Roofed Minneapolis Central Library is a Civic Lesson on Eco Design.” Minneapolis has one of the greenest libraries and the third largest library collection per capita in the US. The Minneapolis Central Library by Pelli Clark Pelli hosts a huge atrium that splits the building into layers of light-filled spaces to help encourage visitors to find a nice book and stay awhile. A series of greenroofs, advanced cooling and heating systems, and low-energy lights cuts the library’s energy use by nearly a third, teaching everyone by example exactly how deep green design benefits everyone.
