Collect Your Retrofits: The design of collective decision-making processes for community driven retrofitting

The deployment of energy reduction actions jointly across multiple buildings at once are much needed to reach the climate targets of reaching a reduction of 3.4 megatons of CO2 for the built environment. In the Netherlands, over 1.5 million homes are part of associations of co-owners VvE (Vereniging van Eigenaren).
Each dweller is accountable for their own energy use, while being constrained with their own financial capacity and a shared will to act with other buildings co-owners. There is an existing and ever growing split between individualized responsibilities and the collective energy transition, which has led to fragmented scale and scope responses to the energy retrofitting challenges.
