The Ministry of Agriculture, Nature and Food Quality stimulates the development of biobased and circular products. We want to use this to reduce the use of (finite) raw materials and energy consumption.
Organic residual flow from the horticultural sector is still a largely untapped opportunity. We challenge you to develop a modular and circular construction system, in which organic residual flows from horticulture are used.
This combination of residual flow and application potentially has a major impact:
- When composting organic streams, about 50% of the fibers are lost, and greenhouse gases CO2, NOx and methane are released
- A lot of energy is required to produce conventional building materials such as steel and concrete
- In order for biobased building materials to substantially contribute to CO2 reduction in construction, it is important to find cost-effective applications for bio-raw materials, while the building culture in the Netherlands still relies heavily on brick, concrete and steel.
The national government and Floriade collaborate in public communication regarding sustainable development: Growing green cities. As part of this challenge, the Floriade wants to realize their entrance building in 2022 as a test case with new biobased circular building materials!
That is of course a first start. This challenge preferably inspires a circular, biobased construction concept that can be used on a large scale for sustainable buildings.
Do you have the solution for this? Then we would like to receive your pitch!
What are we looking for?
The Floriade will open in 2022 and the entrance buildings should be made of materials that have a clear link to horticulture. The Floriade is the only World Exhibition in the Netherlands and pre Corona it was expected to attract 2 million visitors.
The entrance buildings must have a sustainable appearance and preferably a wow factor due to the special use of materials or design. As part of this challenge, the Floriade wants to have their entrance building realized in 2022 as a test case with new biobased circular building materials.
Preferably, the entire construction consists of biobased materials (with the exception of glass and the installation). Afterwards, the building should be easily dismantled and will probably be used at the Greennest Experience in Hoofddorp or Amsterdam.
We are looking for a modular and demountable construction system with a description of the various parts thereof. You are free to determine the nature of the construction system, as long as it can be dismantled and reused elsewhere after the Floriade. A clear vision of disassembly scores in the assessment.
The construction system must be realized with residual flows from horticulture as a basic raw material. Consider, for example: eggplant and tomato stems, tomato leaf, pepper knots, champost, chrysanthemum stems, freesia leaf, etc.
The material made from the residual flows may, for example, consist of pressed plates, cultivated parts of mycelium, insulation material in the form of flakes / granules, or combinations thereof.
The submitter (or collaboration of submitters) must be able to demonstrate that he / she can realize the building (or have it realized), i.e. that the proposed techniques are close to market maturity.
The entrance building consists of 8 cash registers and approx. 40 m2 back office (approx. 50 m2 in total, it must be wind and waterproof and the insulation value must be at least in accordance with the building decree (walls Rc 4.5, roof Rc 6).
The proposed construction concept must clearly indicate which construction structure and material choices have been made per construction element (such as facade parts, cavity leaf, frames, floor) and provide a substantiated indication of the costs.
There is NO design of the building itself included in the submission, the design will be done in the first phase after winning the challenge in consultation with the Floriade.
The proposals submitted will be assessed on the following aspects:
1 Contribution to a biobased use of horticultural waste:
The higher the percentage (volumetric) of building materials that is biobased en sourced from horticulture, the better.
2 What architectural possibilities does the proposed solution offer?
The appreciation for a material rests not only on its technical properties, but also on its appearance and architectural possibilities for large-scale application. What special properties does the proposed building system have? For example, is it easy to build special shapes? Is it cost-effective to realize? Is it fireproof?
3 Cost
Give an indication for a blind facade 6 meters long and 2,6m high. Specified for material and Voor blinde gevel van 6 meter lang en 2,6m hoog, gespecificeerd naar materiaal en placement.
4 Demountable
How easy is it to demount and build up again in another place.
What are we not looking for?
Biobased solutions using straw or only wood (i.e. without horticultural waste) do not meet the requirements, but can serve as a source of inspiration.
What is there to win
This challenge is divided into two phases:
Phase 1 The winner gets the opportunity to make a design in collaboration with the Floriade and the Ministry of LNV on the level of detailed working diagrams and cost buildup. For this phase €5.000,- is available.
Phase 2 The winner can realise the 'Entreegebouw' on the Floriade as a pilot, if the design and realization is up to the standards and whishes of the Floriade. For this phase up to €50.000,- is available.

Achtergrondinformatie
The Sky garden is an example of a pavilion (which was innovative in 2018) with a clear link to horticulture.
Examples of modular construction concepts include: Blokiwood, Ursem (hotel rooms hotel Jakarta), Wikkelhouse, and Sustainer Homes. These concepts are not always simple to disassemble and reuse.
