The heat maps allow users to explore our heating demand and potential supply sources from a special perspective.

Background

Heat mapping describes the spatial distribution of heat demand based on information on various factors:

 

  • the building type (a residential dwelling, a commercial or public sector building or an industrial site),
  • the type of fuel used to generate the heat,
  • other metrics such as the area of buildings, and current and planned energy efficiency measures.

The heat map is based an analysis of detailed high resolution sector specific data. This is used to calculate heat demands. A number of datasets and assumptions have been used in the construction of the map. These are detailed in the information on the map layers.

The combination of a detailed dataset and spatial distribution means that heat maps can be used for analysis. The analyis is of community energy schemes, or other schemes where spatial and geographic information may be of use. It is hoped that these heat maps can aid the following:

  • researchers,
  • consultants,
  • utilities, and
  • decision makers interested in assessing the potential for district heating, energy efficiency and other infrastructure for locations across the country.

The heat map includes public sector loads. However the availability of data at a national level describing the public sector buildings is limited. Therefore only public sector buildings heated by gas, and which could have locations identified, are included in the dataset.

What you will find in this map

Large heat users

Provides the location of industrial sites within the Large Industry Energy Network group. Companies are eligible to be a member if they are either:

  • spending at least €1 million on energy annually, or
  • are certified to or pursuing ISO 50001 certification.

Certain commitments must be fulfilled by companies signing up to LIEN, e.g. Developing an energy management programme and action plan, setting and reviewing energy targets, and reporting annually on energy performance.

Estimated annual heat demand (2015 and 2025)

Displays heat demands for domestic and non-domestic (public sector, commercial, and industrial) buildings. These are:

  • annual heat demands in MWh (both for 2015 and 2025),
  • annual demand per m2 of building footprint MWh/m2,
  • linear heat density MWh/km.

It also displays water network lengths, gas network lengths and road lengths used for the calculation of linear heat density. Additionally, key energy supply technologies including power stations.
