Building has to change quickly.
Materials such as concrete, brick, steel, insulation materials (all produced at high temperatures) lead to masses of CO2 emissions.
Biobased materials, on the other hand, store CO2. Strotec builds constructively with straw and wood and thus offers a solution.
How....?
By replacing traditional building materials with regrowable, bio-based materials, we ensure that the (currently still highly polluting) construction sector becomes cleaner and actually ensures Carbon-capture. Especially in large-scale construction projects, this will make a vast impact.
That an urgent matter because -according to the Paris Agreement- in NL we are already almost at our CO2 limit. In the near future, a CO2 lockdown is certainly not imaginary. The CO2 capture in our façades (approx. 98 kg/m2) provides compensation.
By building bio-based with straw and wood, it serves more purposes:
* The high insulation value, the additional heat buffering and the vapour-permeable character of the façades ensure that a minimum of heating, cooling and air treatment installations are required.
* Subsequently, those installations consume minimal energy. All this results in lower purchase-, energy-, maintenance- and replacement costs.
* Finally, this way of building is optimally circular:
-The facades as a whole can be reused
-The facades can be dismantled again into straw elements &
-At the ultimate end of life, the biobased material can be brought back into the cycle
Scaling up Prefab & Biobased in practice
In the tiny STROTEC Tower we show how we are actually going to scale up building with natural building materials (such as wood and straw). To achieve this larger scale, we are focusing on prefab.
We use floor-to-ceiling wood-straw elements from EcoCocon. We combine them into complete structural façade parts with windows, doors and frames and finishing layers. That's STROTEC GEVEL (Strotec Facades); a partnership between Bouwbedrijf Gebr van Herpen from Heesch and Strotec. The façade parts are delivered to the construction site - with millimetre accuracy. This allows us to meet the modern market demand in the construction industry, but with optimal bio-based materials.
And that is already happening in practice.......
Where....? What then.....?
We are doing so with a large housing project in Eindhoven of Housing Corporation Trudo in the Rustenburgstraat. This concerns 89 ground-level, social housing units in wood and straw designed by Faam Architects. Building will start at the beginning of '25.
Another striking example of upscaling is the development and construction of the Salix Tower in the Meerlandpark in Eindhoven. This project is an in-house development by Architecten en-en, Bygg Architecture & Design, BIEB and STROTEC and is now being developed in collaboration with financing developer EarthY from Amersfoort and as intended builder Moeskops from Bergeijk.
It concerns 58 homes:
- in a collective and cooperative form of living
- in stacked neighborhoods
- in a building with hardly any energy demand due to the STROTEC FAÇADE
- has an optimal indoor climate
We show a model of this 14-layer Salix tower.
Finally, we present the Bestsellers project that is in preparation in Lelystad; a mega distribution center in which approx. 40,000 m2 of straw façade has been conceived. (= façade area of approx. 1000 houses). It is designed by Henning Larsen Architecture (DK) and is being developed in cooporation with EcoCocon.
