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

CNCP - The building site starts (FR)

Posted on

The construction of the future CNCP training centre is started! With the first batch of asbestos removal/demolition carried out by the company Eccodec during a week and a half of work. This future building will house the CNCP training centre with a theoretical training room and a practical training area, as well as reception areas for trainees. The project involves both rehabilitation and construction on a site that includes two buildings listed as historical monuments: the Feuillette house built in timber frame and straw insulation (1920) and its shed. After 4 versions of sketches, the project was validated and the building permit was submitted in June 2021. The rehabilitation part will be carried out with an ITE with wood wool. The new building will be built in wood with local essences, prefabricated walls and straw insulation. Read More

EPD – Environmental product declaration for Straw as insulation material (UK)

Posted on

The purpose of this EPD is to compile environmental data of materials and products used in the built environment. So that the environmental data can be used in calculations of buildings and / or civil works or an LCA of the final product. Find all the details of the report on the ESBA website: https://strawbuilding.eu/epd-environmental-product-declaration-for-straw-as-insulation-material-in-uk/ Read More

Events

Rencontres Régionales Bois et Paille (FR)

, Lille

The CD2E and FIBOIS Hauts-de-France organised the eighth edition of the Regional Meetings dedicated to wood and straw construction. Presentation of the CNCP eco-construction training centre building. The realization of the new CNCP eco-construction training centre was in the spotlight with the presentation of the project by Patrick Thomas, associate architect at VIVARCHI (project manager). How does the training centre construction project enhance the existing heritage (4 buildings are listed as historical monuments) by constructing a new building and also rehabilitating existing buildings? In accordance with the UP STRAW project, Interreg ENO programme, the CNCP has favoured bio-sourced materials: wood prefabrication and straw insulation (80 m3 of straw) as well as local companies. More than 200 people attended this event with many sectors of activity represented: companies, local authorities, architects and farmers.

The grand opening of the Bale House Visitor Center (UK)

, Hastings Country Park Nature Reserve (UK)

Save the date! The grand opening of the Bale House Visitor Center will take place on Saturday, June 4 A day of events is planned from 10 a.m. to 4 p.m., with the opening ceremony taking place at 12:30 p.m. The 'Bale House' is the new Visitor Centre in Hastings Country Park Nature Reserve. It is the first public straw bale building in Hastings and will act as a community facility and café with interpretation that showcases the management of Hastings Country Park Nature Reserve. From the foundations to facade, it is constructed from natural and recycled materials which are healthy, fireproof, breathable, and they lock up carbon from the atmosphere, recycling agricultural by-products. It requires next to no energy to run and due to the level of insulation will require no additional heating to keep people comfortable. This sustainable and exemplary building was designed by Cave Cooperative architects and built by a consortium of straw building specialists led by Huff and Puff Construction and Green & Castle.

Opening ceremony of the largest straw-insulated building (DE)

, Benedictine Abbey of Plankstetten (DE)

Opening ceremony of the largest straw-insulated building, "Haus St. Wunibald", in the Benedictine Abbey of Plankstetten, on 1 April 2022. This is the celebration of a milestone in ecological building in Germany. It was very festive and high representatives from church, politics and society were present for this event. Bavarian Prime Minister Markus Söder, praised straw building as a unique answer to the climate crisis! He listed the main advantages of straw construction and mentioned the fact that in Germany, more than 20% of straw remains unused in agriculture every year. This would be enough to insulate more than 350,000 family houses. The fact that a German Prime Minister is now talking about straw building is a milestone in the history of this ecologically remarkable and market-ready building method.

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.
