The overall aim of the THERMOS project is to provide the methods, data, and tools to enable more sophisticated thermal energy system planning rapidly and cheaply.

THERMOS aims to accelerate the development of new low-carbon heating and cooling systems across Europe, and enable faster upgrade, refurbishment, and expansion of existing systems.

To this end, THERMOS is:

• Developing a state-of-the-art modelling methodology for address-level energy system maps.
• Using this methodology to produce a set of these maps for the pilot cities involved in the project.
• Creating modelling algorithms for analysing these maps in order to support planners with decision making.
• Testing these methodologies in four replication cities.
• Developing and publishing free, open-source software for use by local authorities or other interested parties.

THERMOS works with 8 cities that will be partnered up as pilot and their replication cities. Pilot cities have been selected to participate in THERMOS because of their vast experience with planning district heating networks. Their extensive knowledge of the challenges facing thermal network planners will help to develop software that reflects these real-world experiences help to understand what best practice looks like - and how it can be replicated in their selected replication cities.
