Rotterdam's Solar-Powered Floating Pavilion
INSIDEflows;Inhabitat   Nov 19.2018

Introduction

The Floating Pavilion is a catalyst for climate change-proof architecture that consists of three connected hemispheres which look like bubbles anchored within the Dutch city’s old harbor. The pavilion is located right in the new center of City Of The Year 2015, Rotterdam. This new center is a hotspot for culture, innovation, sustainability, festivals and culinary novelties.

Reason to Be Selected

The Floating Pavilion is a unique floating venue in the center of Rotterdam. It can be rented partly or entirely for conferences, exhibitions, presentations, receptions and dinners.The Floating Pavilion offers extended value to meetings through its innovative and sustainable character. Especially when it comes to topics like innovation, sustainability, cleantech or the future of your organization it is a unique and perfect location.

Highlights:

Many innovations have been incorporated into this project. In terms of both materials, sustainability and construction. Its facade is composed of modular hexagonal forms, made out of steel and covered with ETFE foil- a material a hundred times lighter than glass, which does not burden the foundation, and is at the same time used as a thermal isolator. The foil is double- layered and filled with air, which contains the warmth inside during the winter and preserves the inner temperature at 21 degrees during the summer. The foundation is a recently patented structure as well, made of expanded polystyrene (EPS) combined with a grid of concrete beams. The floating foundation enables the structure to be built on water and then shipped to its planned destination.

Details

To heat and cool the rooms, under- floor heating and FiWiHex-units (efficient heat- exchangers) are used. This heating system is sustainable because it is a low- temperature heating and it uses radiation instead of convection of heat and cold. The exposition space is passively heated by the sun and by lock ventilation. In the facade, large hatches and glass slats were placed that can be opened for ventilation. To prevent too much exposure to the sun, the cushions on the facade differ in transparency- they are less transparent in the higher layers and more transparent in the lower ones. This area serves as a transition space between the inside and the outside, with maximum temperature of 15 degrees C. The auditorium, however, has vacuum- tube solar collectors placed on the ceiling which gather the Sun's warmth to transform it into cooling. This cooling system is called adiabatic evaporative cooling and works via an intelligent air- treatment cabinet. The Pavilion also purifies its own toilet water using a three- tank IBA system, which consists of three different purification processes which take place in three separate tanks- physical, chemical and biological purification. Drinking water is also purified and is re- used as rinse water as much as possible. Whatever is left can safely be discharged into surface water.

Conclusions

Rotterdam has plans to build floating urban districts–for living, shopping, working and recreating on the water–and of the 13,000 climate-proof homes planned by 2040, 1,200 of them will be on water. The Floating Pavilion is a realistic innovative approach to prepare for difficult times ahead, we will soon be able to admire real floating sustainable districts in this Dutch futuristic city.
