Very comprehensive, neutral presentation of the market situation and the options for action. In individual earlier webinars, I often found the presentation to be too one-sided, as the problems and risks of new energies were not addressed at all. Every company will have to find its way somewhere between new and old energies. I would be burningly interested in the actual performance of the installation of new energies, especially the performance / experience values of heat pumps and PV, especially in multi-family houses or medium-sized commercial / industrial companies up to 100 employees. We urgently need actual experience values to make the right decisions! What is the primary energy factor in the different constellations: Underfloor heating, insulation, windows, supply temperature. What is the performance of district heating especially in multi-family buildings? Thank you very much I follow and benefit from your webinars.
