This project, submitted by the non-profit association "Au pays de l'Attert", was introduced as part of the 8th Interreg IVA call for projects. The following actions will be carried out over two and a half years in the cross-border Attert Valley area: 1. Analysis of energy production and consumption in municipal buildings 2. How to involve the population of the Attert valley in energy production? 3. New renewable energy concepts: - establishment of a project of 4 positive energy houses - feasibility of a wood chips sector - district heating networks - drying of agricultural materials via the use of surplus green electricity or the recovery of heat emitted by a photovoltaic installation or the use of heat from a biomethanisation plant 4. Adaptation of urban planning regulations in order to authorise the construction of buildings with optimal energy performance (e.g. roof overflows to the south, bay areas, healthy materials, etc.) 5. Setting up a scientific and recreational infrastructure to respond professionally to the demand of multiple visitors. 6. Awareness-raising, promotion and training campaign on the use of renewable energies
