Floriade Expo 2022

Showcase for future (housing) construction of Noordereng Groep & partners

Ede, June 4th, 2021 – PRESS RELEASE

The innovative consortium of the Noordereng Groep (Ede) is the chosen winner to realize the Dutch Innovation Experience (Di-X) Government Pavilion in Almere. The pavilion is a showcase for future (housing) construction and connects the spatial tasking with the transition tasks in the Netherlands. The design introduces the ‘HoutKern Building Method’, a circular concept that makes it possible to build many new homes in a short time, in a sustainable way and with low emissions.
Floriade Expo

The consortium, led by the Noordereng Group, consists of Heko Spanten, Oosterhoff Group / ABT, DP6 architecture studio, Studio Nico Wissing, Hedgehog Company and De Groene Jongens. The HoutKern Building Method was developed by partners of the consortium as one of the solutions for the Dutch construction issue. This sustainable construction method is the basis for a very versatile pavilion, reusable in different configurations, green and made entirely of biobased materials. Gerben Kuipers, CEO of the Noordereng Group: “We are proud and delighted that the jury has selected our entry. We will surprise future visitors with a ready-made and sustainable solution for the housing challenge.”

Sustainable innovations for future (housing) construction

The Di-X Natural Pavilion is in line with the “Growing Green Cities” Floriade Expo theme and wants to inspire visitors how we as a society can design nature-inclusive living, working and living. The building is equipped with the most sustainable innovations. For example, it shows the possibilities of applying greenery in the built/stacked future living and working environment, new forms of rainwater collection, optimal use of natural daylight, ventilation and minimal energy consumption. Parametric design is applied to optimize the design in the field of architecture, construction, building physics and sustainability. An example of this is the link with the parametric Environmental Impact Monitor, whereby the CO2 footprint of the building construction is calculated in real-time on the basis of design data.

Showcase for the most circular and biobased pavilion

The pavilion consists for 95% of biobased materials that largely originate in the Netherlands. For example, use is made of Dutch wood from the FSC-certified forests of Staatsbosbeheer. The Di-X Natural Pavilion will be an inspiring experience. In the 10 exhibition spaces, the visitor is taken along in the development of, among other things, new biobased materials, grown by Dutch farmers, which are processed in circular building materials. In the pavilion, the visitor experiences the experience of nature-inclusive construction and how the building is part of the local ecosystem.

Flexible and sustainable building with the HoutKern Building Method

The HoutKern Construction Method is a sustainable construction method that can make an impactful contribution to the upscaling of circular and biobased construction. It is a modular construction system, in which the modules can be built as ‘large building blocks’ in various configurations up to 80 meters high. Use is made here of so-called dry connections between parts, which guarantee flexibility and releasability. This ties in seamlessly with the circular construction economy for the future; changing destination and use of houses and other types of buildings will increasingly take place.

Industrialization of wooden modules is a Dutch breakthrough

Making buildings from fully industrially manufactured wooden modules is new for the Netherlands. The production of the units has been fully industrialized into a completely modular and digitally controlled process. The processing of raw materials, installation, installation of electricity & water and the complete dismantling of the modules is carried out in the factory at Heko Spanten. The modules are delivered ‘plug and play’ to the construction site on the Floriade Expo site.

Good environmental performance scores with an affordable business model

The HoutKern Construction method provides a cost saving of 20%, a shorter construction time of 50% and a substantial reduction in emissions. Due to light foundations and full industrialization, digitization and high-quality use of biobased materials, the environmental impact is minimal. The Di-X Natural Pavilion has a very high sustainability performance with an Environmental Performance Building score of <0.25. The Di-X Natural Pavilion is part of the TNO development program to accelerate zero-emission construction. TNO and a number of experts contribute to these innovations, including for the digitization and materialization of the pavilion.

Di-X Natural paviljoen is een circulaire business case 

The pavilion will be completed in six months and delivered on December 31, 2021. After the Floriade Expo, the pavilion will be given a second life as a traveling nature pavilion. Due to the demountability, adaptability and expandability of the HoutKern Building Method, the Di-X Natural Pavilion can be seen in various forms in the future. It is a source of inspiration for the construction sector. The circular business case is jointly financed by the national government and the consortium.

Tender procedure Floriade Expo

The tender “Design & Build Dutch Innovation Experience (Di-X)” for the Floriade Expo 2022 was launched on 11 May 2021.
