Dans le cadre du projet Äerdschëff, CELL a le plaisir de co-organiser avec Twiza cette formation sur l’organisation des chantiers participatifs.

Objectifs pédagogiques

• Préparer et réaliser un chantier participatif dans de bonnes conditions de convivialité et de sécurité.
• Appréhender le contexte juridique et assurantiel.
• Garantir la réussite du chantier participatif au regard du projet dans son ensemble, et en fonction de ses besoins et de ses ressources.


Ce sont les erreurs qui coûtent cher. Faites le point sur les bases pour que cette expérience reste un moment de convivialité qui accélère et dynamise votre chantier, une source de plaisir et non de stress.

2. Préparer le chantier participatif

4. Evaluer et équilibrer ses ressources et ses besoins

Particuliers qui envisagent d’avoir recours au chantier participatif dans le cadre de leur projet.

Aucun. Justement, le but de cette formation est de reprendre à la base. Attention toutefois, c’est une formation intense pour loger en une seule journée.

Redesign the Steering Group 2018

Dear Groupe de Pilotage,

2017 is coming to an end. With the new year and the construction of our Äerdschëff approaching, we would like to propose a redesign of the GP meetings and involve you to a greater extent.

The GP meetings will be held once per month, every second Tuesday of the month. Here are the dates for your diaries. All meetings will be held at CELL, unless otherwise advised:






Until now, the GP meetings have been very colourful talking groups where we could exchange and discuss ideas. In 2018, we want them to be more practical and based on four different working groups, each one with a specific set of tasks. The working groups are


2-COMMUNICATION (led by Agata)

3-FUNDING (led by Katy)

4-MATERIALS (led by Gaia)


This working group will be led by Loïc with the help of the Äerdscheff team and will mainly focus on the organization and coordination of the volunteers that will come to help us building. The main problems to solve are:

  • Volunteer camp design (space, chores rota, accommodation, daily schedule, phases of building)

  • Registration design (how to get people to sign up smoothly and with commitment – here there is an overlap with Communication WG)

Here the trello board previously created by Rodrigo, Nuno and Leo.

If you enjoy and have some experience organising groups, workshops, if you have some good contacts here in the region and you want to help us, join this group and coordinate with Loic and the Ä team!


This working group will be led by Agata with the help of the whole Ä team and will mainly focus on reaching out to the volunteers and communicating with them. The main tasks will be finding the contacts of the different earthship groups around EU and world and involve them in our project.
If you enjoy and have some experience in communication and advertising and you want to help us, join this group and coordinate with Agata and the Ä team to advertise our project!


This group will be led by Katy with the help of the whole Ä team. The focus of this group will be securing funding and sponsorship, with emphasis on the post-construction time.

If you enjoy and you have some experience in writing funding bids (in French and English), or like communicating with a diversity of people, and you want to help us, join this group and coordinate with Katy and the Ä team.


This is the most practical group and will be led by Gaia with the help of the whole Ä team. The group will perform various tasks around preparing the building phase:

  • Getting and sorting materials

  • Cleaning and making bottle bricks

If you enjoy and have some experience with power tools and you want to do practical things, join this group and coordinate with Gaia and the rest of the Ä team.

Here you can find a google spreadsheet where you can subscribe to you r favourite group, you can also join more than one!

The Äerdschëff team would like to thank you for the interest shown during 2017 and your help during this long process.

We hope that you will support our project even more in the upcoming year!

We would like to wish you an amazing Christmas time and a great start of 2018!

Your Äerdschëff Team

“Solar Experiment Lets Neighbors Trade Energy Among Themselves”

“Solar Experiment Lets Neighbors Trade Energy Among Themselves”

” Brooklyn is known the world over for things small-batch and local, like designer clogs, craft bourbon and artisanal sauerkraut.

Now, it is trying to add electricity to the list.

In a promising experiment in an affluent swath of the borough, dozens of solar-panel arrays spread across rowhouse rooftops are wired into a growing network. Called the Brooklyn Microgrid, the project is signing up residents and businesses to a virtual trading platform that will allow solar-energy producers to sell excess-electricity credits from their systems to buyers in the group, who may live as close as next door.

The project is still in its early stages — it has just 50 participants thus far — but its implications could be far reaching. The idea is to create a kind of virtual, peer-to-peer energy trading system built on blockchain, the database technology that underlies cryptocurrencies like Bitcoin. “
