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 m ² 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.

Additional Info

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.” ~2012 Mecanoo profile; see current Mecanoo 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?

Current Green Roof Trends in Germany (2011)

December 17, 2011 at 11:43 pm

Following a recent survey to its member companies, the FBB (German Professional Green Roof Association) estimates that around 8 million m ² 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

– Hello, I’m Anjuli Velazquez and welcome to This Week in Review for November 4th on  GreenroofsTV.

–  Project of the Week

– Our project of the week is the  Cuartel de Ballajá Greenroof built in 2011 in San Juan, Puerto Rico. The Ballajá Infantry Barracks Building was constructed by the Spanish army between 1854 and 1864 and is one of the most impressive structures made by Spain in the New World. Used until 1898 as infantry barracks and permanent housing for approximately a thousand soldiers, it consisted of rooms for officers, solders and their families, storage, kitchens, dining rooms, jail cells and stables for horses. Today, the Ballajá Barracks houses several educational and cultural organizations, namely the Museo de Las Américas, on the second floor of the building since 1992.

The extensive  rooflite ® green roof was part of several “green intervention” projects done to the barracks, including a 151.2 KW PV system with 720 solar panels. Completed less than a month ago, the new 24,000 sf green roof was designed by the architect Edmundo Colon with the help of GRP David Aponte. The green roof also has greenwalls and an artificial wetland built to manage higher roof storm water amounts, which is used on a needed basis as the supplemental irrigation system.

– “In the News“

– Joe Eaton of theSF Gate  says “California Academy of Sciences‘ roof is thriving.” The academy’s roof is planted with beach strawberry, bush monkeyflower, and many other species of herbs, shrubs, annuals, perennials, grasses, succulents, and ferns. One “success story” was self-heal, prunella, a purple-flowered mint herb, Frank Almeda, California Academy of Science’s senior curator, said “bumblebees just love it.” Also loving the roof are butterflies, they are really happy with the tall yellow-blossomed Hooker’s evening primrose.

Part of the roof’s message is that a plant and animal partnership is very important. Almeda said, “it’s important to learn that plants don’t just make it on their own…they have a long evolutionary partnership with pollinators.” The roof attracts insects and other creatures like bumblebees and honeybees, white and West Coast lady butterflies, and even a red-tailed hawk. Human visitors love the roof, too – and you can learn more when you take a tour.

– Emma Dutton and Bethany Leggett of Medill Reports: Chicago, report on “Indoor harvest of fresh produce part of new green arrivals at O’Hare.” They say “the latest modernization at O’Hare International Airport includes an aeroponic vegetable, herb and edible flower garden.” Some of the restaurants are using lettuce, cilantro and basil grown from the 26 vertical columns inside the airport.

Tim Blank, founder and president of Orlando-based Future Growing, designed the aeroponic garden for O’Hare and said, “in this particular case, we’re growing all this food crop right here from farm to table. So we’re bypassing the transportation and the chilling and all those components that create a huge carbon footprint to the plant. Water is one of the number one issues that we’re dealing with in this country. There is a water crisis, especially out West where most of this food is grown.” The indoor garden is one of the latest green initiatives by the Chicago Department of Aviation to increase the sustainability of Chicago airports, showcased at the fourth annual Airports Going Green Conference.

By the way, the O’Hare Aeroponic Garden is featured in the Greenroofs.com 2011 Top 10 List of Hot Trends in Greenroof & Greenwall Design.  If you missed our inaugural Virtual Summit, the next time you can see Linda and Haven’s Top 10 presentation will be next month in Philadelphia for the 9th annual Cities Alive Green Roof & Wall Conference!

–  Project of the Week

– Our project of the week is Harvard Graduate Student Housing at 29 Garden Street built in 2004 in Cambridge, Massachusetts.  The former police station from the 1920s was renovated in 2003 with the greenroof installed the following year.  The six-story complex has 75 apartments for the graduate students and “the garden courtyard provides a beautiful outdoor amenity space for residents and has made this housing building one of the most popular places to live on campus.”  The American Hydrotech project profile states, “The once unsightly rooftop is now a 10,000 square foot Garden Roof ® providing pleasing views and helping to add a sense of place and community for the graduate student residents there.  The Garden Roof will significantly increase the life expectancy of the roof and is also helping to control stormwater runoff.”  The rooftop plantings include a mix of succulents, sedums and delosperma, drought tolerant varieties that are perfect for Boston temperatures.

– “In the News“

–  Roberta Cruger of Treehugger reports on “The 9/11 Memorial & Museum’s Focus on Sustainable Design.” She says “From a green roof to locally harvested trees, the National September 11 Memorial and Museum opens on the 10th anniversary of the attack on the World Trade Center with a dedication and much media coverage of every angle, including Steven Spielberg’s The Rising: Rebuilding Ground Zero.” A grove of more than 400 swamp white oak trees, all harvested from within a 500-mile radius of the World Trade Center, on the Plaza act as a beautiful green roof for the 9/11 Memorial museum, the train station and other facilities 70-feet below street level. These trees are meant to represent the renewal of life in their natural cycles. The irrigation system includes stormwater capture in underground storage tanks to save energy and resources and the site is seeking LEED gold certification.

– The San Francisco Chronicle announces that “Academy of Sciences [is] honored with another green building award.” The say “everyone’s favorite combination of aquarium, planetarium and natural history museum has received a second Platinum rating from the council’s LEED program.” And this one’s for operations and maintenance. The extensive vegetation on the living roof consists almost entirely of natural species and the glass walls allow views from 98% of occupied spaces. Also, they use 100% recycled paper in all its printers and they are all Energy Star-rated.

– Caroline McMillan of the Charlotte Observer talks about “Green roof sprouts up in the suburbs.” LEED-accredited architect, Rebecca Fant and her mechanical engineer husband, John Alday, have recently installed their very own greenroof. Their porch roof was in need of restoration, so they decided to go green with the help of LiveRoof ® vegetation. They aren’t reaping the full benefits of greenroofs like managing stormwater runoff, keeping their house warm in the winter and cool in the summer yet because their greenroof is just over their porch but Fant says, “it’s a little teaser for what we’re trying to do inside the house, as we renovate and improve the energy efficiency and other environmental features.”
