About the project

In recent years, there has been a large increase in the number of retrofits in the building sector, largely as a result of EU policies that are aimed at increasing energy efficiency of the building sector, with a particular focus on the most energy-intensive assets.

The RetrofitHUB project fits perfectly into the realization of these goals, by providing the necessary, reliable knowledge on effective energy renovation and engaging key stakeholder groups, including facility managers, condominium representatives, tenants, representatives of local authorities, or experts.

The aim of the project is to develop and deliver training for entities involved in residential property management on the competent implementation of renovation initiatives. The project also aims to develop a guidebook that provides a compendium of knowledge on effective implementation of retrofits for the benefit of the environment and society.

The Retrofit HUB project is part of the European Climate Initiative (EUKI) – an initiative of the Federal Ministry for Economic Affairs and Climate Action (BMWK) to strengthen cooperation in the EU in the further development and implementation of its ambitious climate policy. Through EUKI, climate actors can learn from each other; the initiative supports inner-European dialogue, the exchange of good practice, awareness raising, and knowledge transfer. The EUKI call for proposals is implemented by the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH.
