Heating and Cooling Supply

The energy-efficient provision, distribution, and use of local and district heating require networks of pipes and infrastructure for energy management that can integrate solar heat in future. Heating and cooling networks are becoming more and more diverse and their operation more and more complex. The key to increasing energy efficiency in cities and municipalities is to integrate and link new energy technologies in the supply and building technology areas.

The aim of funding in the heating sector is to improve grid-based heating and cooling supply systems in terms of the primary energy, exergy, economics, and ecology. These include both centralized and decentralized supply structures. Interconnecting the sectors allows the grid-based heating supply system’s flexibility to contribute significantly to the success of the energy transition. In order to overcome the challenges associated with this, the heating networks have to be digitally integrated with each other.

Different aspects are researched in demonstration and pilot projects, such as transforming the heating and cooling supply systems in existing building stock, increasing the flexibility of such supply systems, sector coupling in districts, the use of hybrid planning procedures, and connecting information, communication, and control interfaces with planning tools. In addition, new technologies and concepts for combined heat and power generation are being researched, including for small output ranges and virtual power plants. Other important topics include new types of piping and installation techniques, innovative measuring techniques for heating and cooling supply networks, plus intelligent house connection stations and grid feed-in stations.
