After the project was officially launched on July 7th (https://www.linkedin.com/posts/energiesprong), the split of the residence was conducted to form two units with one of 40 dwellings included in the MustBe0 demonstrator, and another of 30, to be then retrofitted. A site visit was organised on December 1st (https://www.linkedin.com/posts/) with the contribution of a regional facilitator, to ensure a market wide address to share all learnings of the project.
