KeepWarm Guidance Document

This guidance document has been created as a means of helping you navigate some of the key issues involved in upgrading your district heating (DH) by using more sustainable energy sources, namely from a variety of viable renewable energy sources and/or excess heat harvestable from industrial/commercial processes. Integrating and fully-switching to these greener DH alternatives makes sense not only at an operational level, but is greatly supportive, if not essential, for the successful implementation of a variety of Europe’s flagship policy initiatives.

This Guidance Document has been translated into the languages of KeepWarm project partners. Find here the different versions:

Austrian, Croatian, Czech, Latvian, Serbian, Slovenian, Ukrainian

KeepWarm Showroom of replicable and bankable DHS pilot projects

The purpose of this Service Pitch Book is to relay the availability of replicable, bankable examples of DH-retrofits for both energy efficiency (EE) and integrating more sustainable energy sources (i.e. RES and/or excess heat, ExH), as well as providing information about national contexts, especially useful to audiences outside a particular country. It highlights the pilot DHSs which have been actively participating in KeepWarm’s activities, giving them visibility as well as stimulating networking opportunities to reach out to them directly for improving DH even further.

Below you can find the Showrooms with the DHS projects KeepWarm is working with in each individual country.
