UP STRAW: Urban and Public Buildings in Straw

Project Summary

STRAW: premium biobased building material

Creating a healthy and comfortable inner climate in buildings and reducing CO2 can go hand-in-hand! Building with straw, in combination with clay, has this effect.

CO2 reduction takes place by optimal insulation and by the CO2 contained in the natural material straw itself. The use of straw and clay creates a healhy, dampopen inner climate.

Straw is widely available and can be applied in new constructions (houses, offices, schools, public buildings). Straw is also applicable for the insulation of existing buildings. Straw can be used immediately from the production location (farmland), without a further processing.

This makes straw the premium biobased building material.


UP STRAW: a collaborative approach to creating straw awareness and use

Heating all of the buildings in NWE accounts for about 15% of the GHG emissions. The implementatie/application of straw as building insulation helps to reduce that in a natural way.

We will demonstratie that in five projects: buildings made of bales, wrapped in straw and created with prefab straw panels. Ready for implementation in the building industry.

Educational programs for architects, constructors and straw craftsman will facilitate knowledge development. University modulair program elements make students aware of the possibilities and application conditions.

Implementation of straw elements in building methodology and Building Information Modelling software will facilitate the use of straw elements in the building industry.

Communicating the advantages, application and the effects of building with straw will create interest in the possibilities and application.

The Belgian and French partners have produced an enriched edition of the 2021 directory in French with specificities linked to these two countries. Called "Guide construction paille" it is intended for public investment. It was distributed at the closing event of the UP STRAW project, on 7 December 2021 in Orléans. Read More

Groundwork Report: Bale House Visitor Centre

Posted on

Groundwork South (GS) supported the development of a new, sustainably built (straw bale) Visitor Centre in the HCPLNR. At the very outset GS helped to secure significant EU Interreg monies to support construction costs, and throughout the build process we have been playing a key role to help ensure a world class sustainable visitor centre is provided for the benefit of the local community and visitors to the park from further afield.

Inauguration of the new building of the Eco-construction Cluster (BE)

, Namur - BE

The CEC has inaugurated its new exemplary building realised in the project UP STRAW. This new building of 400 m2 is the demonstrator of innovative techniques: half logs and straw, 3D prefabrication and without foundations. The architectural firm Hélium 3 and the contractor Mobic offered us a guided tour of the site. The walls of the building are made of raw wood for its internal and external faces with the use of machined spruce half-logs, and compressed straw for the insulation (121 m3). This building is the first tertiary building of this size in Belgium to benefit from 3D prefabrication. Finally, the installation of the building on screwed steel piles allowed a construction without concrete, preserving the ground and its permeability, and the possibility of a deconstruction without impact on the grounds. An audience of around 200 professional and institutional guests attended the opening ceremony.

2000 straw bales pressed for monastery building / Germany

, Benedictine Abbey in Plankstetten, Germany

The info day "Experience straw bale building" including a live bale pressing action planned for Saturday, March 21st had to be canceled due to Corona. Nevertheless the pressing of more than 2000 straw bales took place successfully. With the bales South Germany’s biggest straw insulated house will be built this summer in the Benedictine Abbey of Plankstetten (Bavaria). The monks are constructing a general purpose building with 30 guest rooms, a kinder garden and parish offices. It took several days to transform about 400 m3 of ecological straw from the monastery fields from big bales into bales right sized for building. For this purpose the prototype of a mobile press machine was brought from Austria to the Abbey. The company Sonnenklee had developed it over three years. The machine produces between 1,5 and three tons of straw bales per hour (10-25 m3 per hour depending on the bale size). With this press house builders can get straw bales from their regional farms and produce them at any time in the year customized to the format needs of the carpentry in charge. The planned public event "Experience straw bale building" was of high interest for journalists, building professionals and lay builders who already had announced to come. Therefore the pressing action was filmed and a video podcast will be published shortly on the building project and the straw bale production.
