An open source tool for mapping and planning heating and cooling systems

Hotmaps is a four year European funded project with sixteen partners including Milton Keynes Council.

The Hotmaps project consortium is developing a tool to support public authorities, energy agencies and planners in choosing the best option for low carbon technologies.

The mapping tool is being designed to assist with planning by providing layers of GIS information on climate, current land use, number and characteristics of existing buildings, population and available resources for renewable energy. This data will provide a quick assessment for the potential of district heat and power systems as well as identifying sites for turbines and solar photovoltaic parks.

The hotmap tool will calculate energy requirements of an area and a range of information to inform energy planning options. Detail down to a 250m2 x 250m2 square will be available for land in all the 28 members of the European Community.

This page will be updated as the tool develops. If you would like more information please contact the team by email at
