Loitz is a co-founder and managing director of the non-profit consultancy co2online gGmbH. Its goal is to support private households in saving energy and reducing their CO2 emissions through digital tools and services (e.g., through the energy-saving calculator or the heating mirror). For her commitment and work with co2online, she has received multiple awards, including the German Environmental Prize (on behalf of co2online). Tanja Loitz is considered a key figure in Germany regarding the digital implementation of climate protection strategies in the private sector.

Thomas is a long-term (renewable) energy enthusiast. Apart from closely following the energy transition in both the electricity and heating sectors, he is the owner of a heat pump, a PV power plant, and a building in which both peacefully cooperate. Currently, Thomas represents the Swedish scale-up Qvantum Industries as Vice President of Government Relations and Public Affairs, aiming to position heat pumps as a viable solution for multi-family buildings. Before his current position, Thomas led the European Heat Pump Association as Secretary General. For nearly 18 years, he represented the industry at European institutions and shaped it to become the impact-driven representation of the sector in Brussels.

Strategist for heat transition communication, EU Climate Pact Ambassador, System Accelerator, member of the EU Heat Pump Accelerator Platform Advisory Board. Anja Floetenmeyer-Woltmann distills complex topics like the heat transition into clear messages – strategically, target group-oriented, and implementation-focused. She develops formats that make technical solutions compatible and enhance political communication. As a strategic advisor for the nationwide “Week of the Heat Pump 2024,” she has developed the central communication content. Currently, she is responsible for the nationwide heat pump information days in ten model municipalities, starting in October 2025.

Prof. Dr.-Ing. Peter Schossig is a leading figure in German energy research and an expert in heat and buildings. He leads the “Heat and Buildings” division at the Fraunhofer Institute for Solar Energy Systems ISE and primarily researches heat pumps and thermal energy storage. Since 2024, he has also held the newly established professorship “Technologies for Climate-Friendly Buildings and Districts” at the Karlsruhe Institute of Technology (KIT). He also contributes his expertise to the International Energy Agency (IEA).

Dr.-Ing. Marek Miara is a leading heat pump expert whose career has been shaped by over 22 years at Fraunhofer ISE. His career is defined by the combination of scientific depth, strategic management, and outstanding communication talent. He is currently working as “Business Developer Heat Pumps.”He laid his academic foundation with master’s degrees from Wrocław University of Science and Technology (2000) and the University of Kassel (2004), and completed his doctorate in 2014 at Wrocław University of Science and Technology.He was responsible for international EU projects and, as “Operating Agent,” led the IEA HPT Projects 50 and 62, which intensively dealt with the global application of heat pumps in multi-family buildings. Nationally, he is active as the Curator of the Heat Pump and Refrigeration Technology research field within the BMWK Energy Research Network.He serves as Vice Chairman of the German Refrigeration and Air Conditioning Association (DKV), is a board member of the European Heat Pump Association (ehpa), and a co-founder of the Polish Heat Pump Association (PORT PC).

Furthermore, he contributes his knowledge as a member of Scientists for Future Germany.As a sought-after speaker, moderator, and explainer, he uses his broad media experience (numerous appearances on television, radio, and in the press) to communicate complex technical facts from research in a target-group-oriented and understandable manner. This outstanding ability to create trust and clarity is the core of his mission to promote the fact-based heating transition.His exceptional commitment and influence on market development have been honored multiple times: These include the Renergy Award in the category “Outstanding Personality in the field of renewable energy and energy efficiency,” the award from the Polish Heat Pump Association PORTPC for his contribution to the market development of heat pumps in Poland, and the “Trendsetter” prize (2023) from the GLOBEnergia organization for his significant influence on the energy and construction sectors.

Kyra Sophie Rimrodt completed her Bachelor’s and Master’s degrees in Economics at the Albert Ludwig University of Freiburg. During her studies, she worked as a research assistant at both the Fraunhofer Institute for Solar Energy Systems (ISE) and the University of Freiburg. During this time, she focused particularly on the topics of unconditional basic income and social sustainability. Currently, Kyra Sophie Rimrodt works as a research associate at Fraunhofer ISE. Her current research focuses on social life cycle assessment (S-LCA), circular economy, and the concept of Heat-as-a-Service. Additionally, she works as a project manager and is responsible for project controlling at the departmental level.

Tom Schulz, born and raised in Hamburg and Schleswig-Holstein, successfully completed both his bachelor’s and master’s degrees in political science at the Albert Ludwig University in Freiburg. There, he focused on legitimacy research and regional organizations in sub-Saharan Africa and worked as an intern for the German Bundestag. With the beginning of his master’s degree, he also started working as a research assistant at the Fraunhofer Institute for Solar Energy Systems, where he supervised and supported international projects on the heat transition, most recently in grant coordination.
