12 types of soils and 6 types of natural fibres from UK and France will be used. These 20 formulations will allow a differentiation of the key aspects of cob.

4 optimised cob mixes will be selected from the 20 mixes tested according to their mechanical, structural, moisture, thermal and acoustic performances. This selection will comply with both French and British legislative criteria.

This method will be selected according to builder’s opinion and economical and environmental costs. A comparison between concrete, actual cob and innovative cob will be made to assure the competitiveness of the innovative cob mix.

The 4 optimised cob mixes will be manufactured at larger scale to ensure that the innovative method associated to these cob mixes are suitable indoor and outdoor. Their performances will be tested in climate rooms and will demonstrate the feasibility of innovative cob house and the reliable characteristics of the designed innovative cob products.

A directory accessible to members of the network via the project website that will firstly identify the stakeholders in the building sector, cob and earth generally, those interested in the issues of reducing CO₂ emissions in the construction, and secondly recent cob buildings with information on the construction mode, site organization and the environmental impacts.

This report will be based on statistical studies from future owners and private and public investors. An economic study will make it possible to specify the impact of the new process on the costs of cob walls. The statistical data from the surveys will make it possible to understand the development potential of the process more precisely and to define the actions to be implemented in order to achieve the obejctives.

A report of recommendations will be drafted based on 6 worshops and 2 general meetings, as well as barriers identified at the beginning of the project, improvement in product and process performance and the results of the demand study. The report will detail an action plan to be undertaken in a second stage of the project (CobBauge 2) by the project partners and members of the network.

Detailed methodology for the practical creation of CobBauge material on the building site. A set of standard design details, plans and 3D models will be published to enable designers, architects and builders to easily incorporate the CobBauge material into their building projects which will include the two pilot buildings.

Two buildings, with the relevant permissions and designed to allow the measuring equipment to be installed. The buildings will use the CobBauge material in walls that are subject to thermal variances to allow the building reflect a true representation of the material’s performance.

To reinforce the prospective demand from the general public, it is important to do real measurements at full scale of the CO₂ emissions and energy performance of buildings in use.

Two buildings will be build: A domestic-scale building in Norfolk and a home in Normandy/Brittany. The building processes will take place over approwimately 1 year from Autom 2020 and Spring 2021 with some staggering between pilot programmes to ensure iterative learning is achieved.

The designed construction phase surveys and media will be used to link the steering group’s and other partner experiences to optimise the construction process. The end of this deliverable will result in a complete data set on the completed buildings, compatible with the monitoring systems, and typical of the types of buildings that will be sold.

The quantitative and qualitative data from the measured use will establish the low energy credentials and associated reductions in CO₂ emissions benchmarked against similar low energy building types such as Passiv’Haus. The assessment of the data will compare the thermal, energy, CO₂ and comfort data with equivalent alternative low energy designs.

The lifecycle and environmental impacts and the embodied energy/carbon of the CobBauge material will be assessed using the appropriate ISO standards embedded in specialist software (Simapro).  The system will produce a draft Environmental Product Declaration (EPD) for the CobBauge material.

Creation of a directory of stakeholders and database of buildings that will be accessible to members of the network.  he directory will identitfy the stakeholders in the building sector that have expressed a desire to use CobBauge and those that are interested in the issues of reducing CO₂ emissions in construction. The database will identify relevant exemplar buildings that have recently build with information on the constructive mode, worksite organization, the environmental impacts, and finally a share/commented bibliography.

The network organisation will result in different outputs, the dissemination of results through exchange workshops, meetings of the years 2&3 and site visits. The validated CobBauge Development Plan will be broadcast to the whole online network. The development plan will purpose future actions, summarise expectations, results and will be discussed by network members into specific workshops at the end of the program to share and adopt it.

Two main sets of target groups need to be trained, professionals & practitioners. The contents will be adapted according to the particular groups, structures for engineers…To ensure innovation, 2 EU transnational exchanges will be planned.

On graduation a list of trainees will be developed and added to the directory, making trainees part of the network and included on the website. A list of the trainees will be developed and added to the directory, making trainees part of the network. Assessed trainees will also be included on the website.
