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.

Action & Activity

Building Database / Long Term Effects (FR)

Posted on

In order to find out the state of the market, the RFCP has launched a regional-scale tool that can be used by multiple investigators. In addition to benefiting from precise quantitative and qualitative data on the sector, these data are an encouraging signal for future developers. They will be reassured by the number of achievements and the extent of the possibilities of straw construction. Read More

Dissemination of Public Procurement (FR)

Posted on

The RFCP (French Straw Construction Network) regularly sends selected public tenders, according to the qualitative criteria they require (labels, bio-based materials, local materials...). At 31/12/2019, more than 300 calls for tenders were relayed, 20% of which expressly required the use of straw. It should be noted that the qualitative requirement of the project owners results mainly in the search for BEPOS and PASSIVE performance. The most dynamic regions are Centre-Val de Loire and Pays-de-la-Loire, where half of the qualitative tenders require straw. Read More

Digital models of straw walls in BIM (FR)

Posted on

The work on the production of BIM objects will describe a dozen walls representative of the main current practices of straw construction. We will therefore find all of the construction systems described in the professional rules of straw construction (filling of frames, caissons) but also, for example, carrying straw. The objective is very simple: - enhance the advantages of straw construction which combines exceptional thermal performance, remarkable comfort, carbon storage, proximity, the pleasure of building and living ... - allow players in straw construction to benefit from the same tools as their competitors - encourage the adoption of straw by those who do not yet know this approach. Concretely, this will result (mid 2020) in the free availability of computer files which will be composed of: - plan and section views of typical walls - lists and quantities of materials used - various illustrations - main technical and environmental characteristics. These files can be imported into CAD (Computer Aided Drawing) software to enrich the wall libraries. The designers will then be able by a simple “drag and drop” to assess the interest of a wall made of straw, calculate an approximate quantity, etc. Read More


Green Architects Day

, University of Brighton / UK

Eileen Sutherland will be discussing the UP Straw project at this event, as part of the project's work on Training of Construction Sector Professionals and Undergraduates. Sustainability at Scale: Size Matters Size matters and so does what you do with it. "When you have more than you need build a bigger table not a higher fence" - Unknown The theme this year is Sustainability at Scale: Size Matters. We will be asking our leading experts if there is any use in our current climate of being a tiny beacon of sustainability or should we be focusing on larger developments. How this can be possible and where the architectural and design community is heading? How does this translate to a city like Brighton and Hove and what is being done here at home? This year's Green Architecture Day promises to be an inspiring day of talks, with stalls and stands, including Meet the Expert and a complimentary light lunch. There will also be a facilitated plenary panel at the end of the day where we explore participants' questions. If public speaking does not come naturally you can still ask questions by ballot.

Fair Salon des Mandataires / Belgium

, WEX - Marche-en-Famenne / BE

The Cluster Eco-construction dedicated a stand to bio-sourced construction materials at the annual meeting of local authorities. This fair is a real opportunity for companies and associations to present their know-how to local authorities in order to develop a better management of municipalities. The UP STRAW team was there to talk about the UP STRAW project and straw as a construction material.
