Flexibilization and Optimization of Heat Pump Systems in Existing Buildings through Secondary-Side Digitalization

Overview

The focus for the restructuring of energy systems is increasingly shifting worldwide towards a more efficient use of energy and an intensified expansion and utilization of renewable energies. This leads to a reduction in greenhouse gas emissions from the en-ergy sector and a decrease in dependence on fossil energy sources and their imports. This is also represented by the United Nations Sustainable Development Goal 7, which focuses on affordable and clean energy. Furthermore, the ongoing revolution in the in-troduction of digital technologies into all areas of life, including building operations, offers new opportunities to address the challenges ahead using intelligent methods.

The digital transformation of heat pump systems, anchored by robust data integration and real-time control, represents a pivotal step toward a more efficient and sustainable energy future. By blending advanced technological innovations with a rigorous assessment of economic, regulatory, and market factors, this project sets a new benchmark in energy system optimization.

Through international cooperation activities, the efficient application of heat pump technologies in new energy systems and buildings is demonstrated, as well as solutions for enhanced energy security and increased use of renewable energies are developed. Furthermore, specific solutions for a sector-coupled energy system and affordable solutions for the supply of buildings with heating and cooling, with a focus on heat pump technology, are to be developed in close cooperation with other TCPs (Technology Co-operation Programmes). This leads to further savings in primary energy, increased flexibility in energy applications, and greater sustainability in building heating.

As further details are refined and new empirical data are collected, the project will continually update its methodologies – ensuring that every element, from high-level objectives to granular work items, remains aligned with the best practices of international energy research initiatives. Enhanced cooperation with international projects, such as IEA DHC Annex TS9, will help further drive innovation and set the stage for broader implementation across building and district-scale systems.
