The private housing industry faces a variety of challenges. In addition to changing political requirements, the megatrends of digitalization and decarbonization are strong drivers of innovation and change. A steadily rising CO2 price and a capital market that is making specific demands on CO2 footprints and ESG roadmaps under the heading of sustainable finance are increasing the pressure to make changes. The housing industry in particular, with its fragmented structure and high level of regulation, requires innovative energy solutions and equally innovative business models. GETEC has made it its mission to support its customers in the real estate industry on their way to Net Zero – and not only in a sustainable way, but also cost-effectively through the use of modern contracting models.
