The purpose of waste heat (WH) cadastres is raising awareness of waste heat energy potential and its sources; encouraging and triggering investment in waste heat recovery; initiating and developing heat concepts for communities and energy providers, for developing national/regional/local waste heat utilization strategies, and for monitoring the progress made.
In the side menu on the right, links to existing cadastres are provided for a number of regions/countries, as well as a joint CE HEAT partnership cadastre.
Waste heat data provided in the cadastres are either based on direct data from companies, calculated from publicly available emissions data for officially approved and monitored facilities (published by the responsible national or regional institution) and/or estimated drawing on literature and other public data.
To obtain relevant data directly from the companies the following survey was used:

Geolocation of data is the key feature of the cadastre. It enables potential investors to study network solutions and investigate which waste heat sources can be recovered together in order to meet a higher or more constant demand.
Each waste heat producing plant needs to be geolocated so that it can be used in the GIS cadastre.
Other relevant characteristics that define waste heat sources included in a WH cadastre are:
- Annual available amount of excess energy
- Average available power
- Annual emission profile (operation time)
- Waste heat temperature at its source
- Heat vector (fumes, water, solid, other)
Based on this data and its visualisation, it is possible to make a preliminary assessment of recovery opportunities. For example: temperature and vector are discriminating factors for the technologies which can be used; while power, total energy and emission profile are essential to match the offer with potential demand.
Available here is the methodology used for integrating WH source data into a GIS system for joint cadastre development that can serve as a useful guidance for further cadastre creation.
