Hotmaps is an open-source heating/cooling mapping and planning toolbox with a default EU28-wide dataset at national and local level. It allows public authorities to identify, analyze, model and map resources and solutions to supply energy needs in a resource and cost-efficient way. Hotmaps can help authorities to develop heating and cooling strategies on local, regional and national scale in line with RES and CO2-Emission targets.

Celcius Toolbox

The Celsius Toolbox aims to be a source of knowledge and inspiration for cities interested in developing district energy (district heating and cooling) solutions. It addresses cities which are just beginning to implement small-scale district heating and cooling networks as well as cities with large established systems endeavoring for even smarter and more efficient solutions.


iBRoad focuses on individual building renovation roadmaps and building logbooks, in support of deep renovations in the residential sector.
