Challenge / Goal

Assessing waste heat potential within the city boundaries for integration in the central district heating system. The focus is on the most accessible inner-city sources, such as data centres and sewers as well as process heat. 

This study is intended to provide an overview of the industry-specific amount of usable waste heat in Leipzig in order to be able to assess the potential for cities with a comparable structure. The methodology for localising and evaluating the waste heat sources is intended to demonstrate replicability for fellow cities.


  1. Development of a localisation concept for urban waste heat sources
  2. Application of the localisation methodology and waste heat data collection 
  3. Analysis and evaluation of waste heat sources 
  4. Further processing of the results
