Spatial Planning: Which Heat Supply Technologies For Which District?

FOR MEMBERS ONLY

In the framework of the Decarb City Pipes 2050 project, Energy Cities organises discussions every last Friday of the month on specific topics linked to the decarbonisation of the heating and cooling sector. These sessions will allow exchanges and capitalisation of learnings and know-how between the partner cities (Bilbao, Bratislava, Dublin, Munich, Rotterdam, Vienna and Winterthur) and a limited number of external cities. Experts, such as the advisory board members, will also be invited to share their insights.

This session will focus on the importance of spatial planning. Heat planning towards a decarbonised future requires a spatial approach: availability of heat sources in the city, spatial density of the heat demand and urban development determine the possible solutions to supply heat for buildings. However, calculating which solutions are more cost-effective in which districts (eg. heat pumps vs. district heating) is not an easy task. It requires data about technologies, buildings, energy demand, etc., as well as the definition of the scope of the calculations (for instance taking into account or not the reinforcement of the power grid due to higher power consumption). The goal for cities is to define prospective scenarios and the key parameters to succeed in the implementation of transition pathways.

This session will present the studies done by the City of Rotterdam and the City of Winterthur to determine which heat supply technologies are preferable in which districts. The speakers will be:

• Rita Gnehm, Planar and Heinz Wiher, city of Winterthur (CH)
• Jillian Benders and Annelieke Vis, city of Rotterdam (NL).
