ACE-Retrofitting

Accelerating Condominium Energy Retrofitting


43% of the European population lives in condominiums/multi-occupancy apartment blocks, which are primarily of low energy performance. How can cities accelerate the energy retrofitting of these buildings?

Objectives of the ACE-Retrofitting project

  • Support the “demand side”: owners and condominium managing structures
    Home owners often lack basic information about energy retrofitting and face a complex collective decision-making process. An owners and condominium managing structures toolkit will be developed to empower this target group, on both technical and social sides of the retrofitting project.
  • Federate the “supply side”: building professionals
    As the retrofitting of entire condominium blocks involves a range of professions and skills, the private sector needs to work together to provide high quality and economically viable works. An operational coaching framework will be developed to improve the building professionals’ capacity to renovate condominiums.
  • Link the demand and supply sides in a common new governance model facilitated by cities
    Cities are the key facilitators and drivers within a territory. Linking the demand and supply sides is crucial to result in the successful energy retrofitting of condominiums. CoachCopro, a collaborative approach developed by the Agence Parisienne du Climat, is central to this strategy and will be improved and adapted for use in other territories. This unique facilitation approach with its central shared web platform for information and project management, guides condominium owners and building professionals through an iterative process which cultivates trust relationships and accelerates retrofitting activity. Throughout each stage of the process, stakeholders are able to communicate with people who can offer them the necessary advice or guidance. The CoachCopro approach will be upgraded and adapted to other national contexts so that it can be used by other local authorities in Europe.

What is Energy Cities doing in ACE-Retrofitting?

Energy Cities coordinates the project, leads the communication and dissemination activities of the project. Energy Cities also co-organises study tours in the partner cities and will launch a roll-out campaign for the replication of the governance model developed within the project in other European cities.
