As in most parts of the Netherlands and Germany, heating of buildings nowadays takes place by combustion of fossil fuels, causing high CO2 emissions. Therefore a transition towards renewable heating is needed. A focus on modernisation of buildings and heating supply systems is required. Introduction, application and evaluation of technology for heating of houses or buildings is necessary. We are investigating opportunities for the energy transition in the East of the Netherlands in the context of the Euregio project WIEfm (Warmth in the Euregio Focus and Modernization).

This project contains different workpackages. Some results of the next topics will be presented.

Comparison of the performance of heat distribution networks.

For this purpose different heat distribution systems are analysed and compared on energy efficiency and CO2 emittance. Sankey diagrams were constructed in order to get insight into the heat flows and losses. This knowledge gives information in which systems are sustainable and which heating systems can be improved.

Calculation model for optimisation of energy supply systems.

A model has been developed with which heat system options for the sustainable energy supply of residential areas can be calculated. The model assumes maximum self-consumption of locally generated, sustainable energy by households and minimal use of the electricity or natural gas network. The model contains energy control algorithms for the prioritization of local energy generation and energy storage.

GIS visualization of heat infrastructure.

A very sustainable energy solution is the use of waste heat for heating houses or buildings. Therefore potential heat sources should be detected and the characteristics of heat users (hot spots) should be known. A GIS (Geographical Information System) web tool will be built up in this project to visualize hot spots and potential waste heat sources. This tool will support local decision making, and visualize opportunities for the energy transition.

Governance structures.

Depending upon the participation of private companies, citizens and/or local government in heat distribution solutions, different governance structures are possible. In this project different types of public and/or private governance structures are being analysed depending upon the characteristics the network. This study is aimed at detecting financial, legal, social and administrative barriers which could obstruct the development of sustainable energy systems.
