Decarbonisation of urban districts: e7 at eceee's 2024 Summer Study

Our expert Klemens Leutgöb presented the innovative model of Heat Transition Cooperatives as part of the eceee 2024 Summer Study. This model offers a promising approach to decarbonising urban districts and addresses the challenge of decentralised gas floor heating systems in existing urban buildings.

Background and challenges

In Vienna, almost 30% of all homes are heated by decentralised gas floor heating systems. Replacing these systems represents a major challenge for a decarbonised heat supply. The available alternatives, such as centralised low-temperature heat supply and deep boreholes for heat pumps, are mostly expensive and require extensive adaptations to the distribution system and improvements to the building envelope. Due to the limited space in urban areas, solutions for individual buildings are often impossible, so cross-building approaches need to be developed.


The role of cooperatives

Cross-building projects require a collaborative organisation in order to realise the capital-intensive investments and manage the operation of the systems. In this context, the Heat Transition Cooperatives model demonstrates how cooperatives can coordinate and balance different legal frameworks, financing conditions and interests.
