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

Training on the integration of biosourced materials into public renovation or new construction programs (FR)

Posted on

ÉCHOBAT, through its training organization, brought together 3 member companies of its network to design a training program for the teams of the real estate management of the Region of the Pays de la Loire. The objective: to strengthen the skills and approach of its operators to integrate ecomaterials in public building projects, particularly in the context of the heritage management of high schools (construction, renovation, maintenance, specific operations to improve energy performance, etc.). Two 2-day training sessions were conducted at the end of 2019-early 2020. Among the projects studied, is the straw wood boarding school of the agricultural lycée Xavier Bernard in Rouillé (86), one of the best ranked projects of the experimentation of the label E+/C- (E4C2). A return of current experience for the community and its project of construction of the high school of Aizenay (85) in frame wood and insulation in boots of straw. Other public and private authorities have already expressed their interest in this training! Read More

Work on the MOOC is progressing (FR)

Posted on

It's official, the MOOC Bulding for change - Naturally has been accepted for deployment on the MOOC sustainable building platform of ADEME ( Environment and Energy Management Agency). ADEME thus provides free access to its platform and finances assistance to the contracting authority for the construction of the MOOC. The UP STRAW working group has put a lot of energy into this deliverable in recent months to arrive at a quality MOOC, on time. The creation must be spread out between now and June-July for a first session in October 2020. Read More

A directory of straw construction professionals (FR)

Posted on

A directory of straw construction professionals in the Nouvelle-Aquitaine region In order to stimulate local dynamics and facilitate the visibility of stakeholders, Résonance Paille and the ODEYS cluster have produced a directory of building professionals in New Aquitaine and members of the RFCP. This was organized according to the main categories: - Professionals (project managers, engineering, construction, others), - Training organizations providing “Pro-Paille” training, - Suppliers of straw bales, validated by Résonance Paille. Identified by the “Pro-Paille” logo, this accreditation, obtained on successful completion of the “Pro-Paille” training exam, certifies that the professional is authorized to design and / or make straw buildings.

Submission of fire test reports Private establishment Emmanuel d'Alzon (FR)

Posted on

Following LEPIR II * and SBi ** fire tests on a wood, straw, plaster frame configuration, funded by SCI Sainte-Anne, contracting authority for the private establishment Emmanuel d'Alzon, Mrs. Nicole Lalanne, president of the SCI, officially donated to the RFCP two analysis reports and authorized: - The RFCP (French Straw Construction Network) to publish and disseminate to a large public the results and the Minutes of these reports. - Any project owner to use the test results for their own projects. And thus demonstrate that straw material has its place in construction! // * The LEPIR test consists of soliciting a facade mounted on a room with 2 levels. The fireplace, consisting of a pyre, is located in the room on the ground floor. / Source CSTB ** Single Burning Item: to subject a product to heat and study its behavior. / Source CSTB Read More

Events

1-day VISITS | December 5 / Belgium

, Liège - Belgium

On December 5 we organized a hole day dedicated to straw construction for students from Helmo school in Liège from technical sales representative section. In the morning, Hugues Delcourt from the Cluster Eco-construction, introduced the students to straw construction. He explained the characteristics of straw: thermal performances, fire resistance, air quality, humidity transfers and life cycle analysis. Then he talked about straw construction: construction techniques, advantages and disadvantages and the legal context. To conclude, he showed examples of straw construction and the costs related. In the afternoon, the students visited first the Waldcube. It is a small pre-fab housing unit designed to be moved and self-sufficient. The structure is made of wood and is insulated with straw.
