A Wider Perspective during the Knowledge Day of Rotterdamse Dakendagen


Introductie (NL)

De afgelopen jaren hebben we tijdens de Kennisdag geleerd over de mogelijkheden van onze daken en het belang van het gebruik van deze onderbenutte ‘bovenstad’. Nu is het tijd om onze kennis in breder perspectief te plaatsen en onze blik over de grenzen te richten. We kunnen met de groeiende internationalisering van Rotterdam natuurlijk niet stil blijven staan en gaan daarom in 2019 met de Rotterdamse Dakendagen international! De Kennisdag – vanaf nu de Knowledge Day – is dit jaar volledig Engelstalig en ook het Dakendagen programma wordt helemaal tweetalig gecommuniceerd. Vanaf nu verder in het Engels!

A Wider Perspective (EN)

Over the last four years, the Knowledge Day of the Rotterdamse Dakendagenhas taught us about opportunities in utilising our rooftops and we witnessed the first entrepreneurs developing daring and innovative projects in the ’second layer’ of our Dutch cities. As we move on from this incubation phase it is time to take a look at what is happening across our borders, to determine the next step in combatting the densification of urban areas in the Netherlands. At the end of April, the complete programme of speakers and workshops of the Knowledge Day will be announced. Read on for a first glimpse of the programme and block Friday the 31st of May from 12:00 in your calendar!

A wider perspective demands an international speaker programme. This year, we give the stage to architects, urban planners and other (green) rooftop specialists from around the globe who will present their vision on city densification and the development of a sustainable rooftop landscape.

We are happy to announce Winy Maas, co-founder of international architecture firm MVRDV and director of the Why Factory, a research institute at TU Delft for future cities, as one of our keynote speakers. Maas will present his vision on a second layer on top of Rotterdam. Together with the Rotterdamse Dakendagen, he is currently working on the realisation of new structural connections between rooftops of Rotterdam to give them a new function to the citizens. What are the consequences of ownership, safety and precarious rights of this extension of the rooftop landscape?

Furthermore, we have Martin Barry of reSITE on stage; a global non-profit organisation acting to improve the urban environment that wants you to be inspired to reTHINK, reLEARN, reIMAGINE, reDO the city landscape. Keynote speaker Jason Hilgefort, Founder of Land Civilization Compositions and Director of FUTURE+ Academy of Urbanism in Shenzhen, will tell us about the totally different approach Chinese cities have on using their roofscape.

Dusty Gedge (UK), chairman of the European Federation of Green Roof & Wall Association will talk about biodiversity on green roofs; and we have Yim Hyun-Jun Seoul on stage, Manager planning team of the Seoul Innovation Park, he’s responsible for the Rooftop Common Land Project in the Seoul Innovation Park and tells the audience all about this special Korean project of sharing rooftops.

After the plenary session, we’ll split up in smaller workshop groups to discuss specific topics in depth. Each workshop is chaired by an international and a Dutch expert to connect international themes to local cases. We’ll have people from the cities of Milan, Lyon, Faro, Nicosia, Prague and Antwerp. Workshop topics and the complete speakers programme will be announced at the end of April. The day will be concluded with the award ceremony of the Dakheld (Rooftop Hero), a prize for the most valuable, recent Dutch rooftop contribution.

We invite all rooftop professionals and other city makers to join our inspiring and innovative Knowledge Day on May 31, 2019 at Kriterion (on top of Groot Handelsgebouw) in Rotterdam! Get your tickets now by using the button below.
