The Hotmaps project aims at designing a toolbox to support public authorities, energy agencies and urban planners in strategic heating and cooling planning on local, regional and national levels, and in line with EU policies.


The beta-version of the Hotmaps toolbox is now online; in the following year the tool will be updated and new releases will be available.


In this version the basic functionalities for mapping heating and cooling in EU members are available. In addition also the first calculation models are available – more functionalities including additional calculation models and the possibility to save and load the status of your work on the toolbox will be available in the final release of the tool.
