DOEPELSTRIJKERS IS AN INTERDISCIPLINARY DESIGN STUDIO FOR INTERIOR, ARCHITECTURE AND URBAN PROJECTS. The beauty of our profession is the ability to respond to the specifics of a place and culture. To dive deep into local conditions and challenges and find tailor-made design solutions.



In the run-up to Floriade, the province will focus on knowledge development and stimulating innovations in the field of Floriade's theme: 'Growing Green Cities'. During Floriade Almere 2022, the Innovation Pavilion will be the Flevoland Pavilion, which will also be available to Flevoland's business community and municipalities. The ambition for the period after 2022 is that this building will become part of the Flevo Campus, where knowledge, education and associated activities will be combined.
The building makes the story of Flevoland visible in a special way. Where once there was only water, a unique area has now been created that is also an average of 5 meters below sea level (NAP). The Innovation Pavilion depicts this in a unique way. A 5-meter-thick layer of Flevoland soil is lifted up to the NAP line.

This can be seen in the shape and in the use of materials. The building makes optimal use of the microclimate with natural sun protection (overhang and row of trees on the south facade), passive heating and cooling and natural ventilation. The light strip above the wooden grandstand stairs is fitted with CO2-controlled windows and sun-resistant fabric. Thus, the indoor temperature and air quality can be controlled naturally all year round. This is in addition to the balanced mechanical air handling system. This form of lean installation is in line with the ambition of "Nature Based Building".

The raised floor is largely made of biobased materials. The loam facade combined with cellulose insulation and the wooden inner leaf are vapor-open detailed. This breathable facade combined with the other biobased materials regulates the moisture balance in a natural way and is demonstrably healthier than regular building. Due to the materials used, the CO2 footprint is kept as small as possible. Closing water, energy, material, waste and food cycles are integrated as much as possible as technical solutions and can also be seen and experienced by visitors in the Innovation Pavilion.

During the Floriade, the kitchen with integrated and edible greenery will be expanded with an exhibition about new solutions in the field of food production. The building as a whole is used to tell the story of food, health, biobased and circular construction.
The building is designed based on the principles of circular construction, largely using secondary and biobased materials. According to Steward Brand (1994), the layers of the building (casco, shell, installations and finishing) are decoupled. As far as possible, homogeneous raw materials and dry compounds were used to promote disassembly and reuse in the future.

The ground floor is equipped with secondary raw materials and recycled materials and products. The floor is made of durable concrete (cement extraction from rubble). The structural concrete floor is monolithic and smoothed and forms the finishing floor. The floor continues to the outside, where recycled windmill blades have been processed into patio tiles.
The steel facade fronts are made from recycled steel and are 100% recyclable. In the middle of the room is a closed box, with toilets and flushing kitchen. The metal stud walls are fitted with circular plasterboard on the inside and covered on the outside with recycled aluminum plates. On the floor are steel columns, which are blindly mounted under and above with countersunk bolts to promote disassembly and reuse / recycling in the future.

The first floor will be a showcase for biobased building. The airframe is made of CLT wooden beams that are also the finish on the inside. The beams are placed on the columns and are fixed dry. The storey-high beams on the outer edge are insulated on the outside with cellulose. The whole is finished with a lime clay facade. The entire floor is modularly designed in elements, and will be assembled on site within 3 weeks. The roof is insulated with insulation plates and waterproofed with Derbigum NT roofing. This was chosen because it is not a petroleum product, and consists of regrowable materials with 25% reuse of recycled roofing. It is fully recyclable at the end of its life cycle.

The installations are largely included in the modular wooden floor. Here we work with construction elements so that they can easily be removed again in the future for reuse or recycling. The concrete floor on the ground floor contains a limited number of installations for the kitchen and toilets. A number of parts, such as the elevator, kitchen, lighting and furniture, are covered by a lease construction, so that the supplier remains the owner of his own product.

Total Cost of Ownership
Whenever possible, the casco is the finish. The ground floor concrete floor, the CLT walls, grandstand stairs, floors and ceiling are examples of this. By using homogeneous materials, they only become more beautiful through wear and use. This reduces maintenance costs and keeps the materials at a relatively high value at the end of the cycle. The "Total Cost of Ownership" also includes the costs of disassembly, adjustment of the installation and, in particular, the expected residual value.

Nature based

The ambition to build a Nature Based building is visible in the form and material usage. The building makes optimum use of the microclimate with natural shading, passive heating and cooling and natural ventilation. The massive earth roof is optimally utilized to create a comfortable indoor climate all year round. The greenhouse on the roof is a winter garden and regulates the natural ventilation. State-of-the-art bio-based and geopolymer materials are applied to with the ambition of keeping the CO2 footprint as small as possible.
Closing water, energy, materials, waste, and food cycles as technical solutions are integrated in a didactic manner so visitors can see and experience these aspects in SubZero. In 2017 the basic building will be realised and will continue to develop towards 2022 for the opening of the Floriade.
