The THERMOS tool is a web-based software designed to optimise local district energy network planning processes and results according to user and project specific requirements such as budget, climate and energy targets. Free to use and built with and for local energy planners, THERMOS places instant address-level mapping and built-in energy demand estimations to design heating and cooling networks within immediate reach.

With heating and cooling responsible for 50% of the final energy demand in Europe, district heating and cooling can be key to achieving the ambitious EU and national energy and climate targets. This is where the THERMOS tool comes in, by making district heating and cooling planning easier, faster and much cheaper. The tool provides advanced energy system data and models in a user-friendly open-source software to identify optimal network solutions in almost any part of the world.
