Germany’s residential sector is a major contributor to CO₂ emissions, with buildings accounting for around 14% of the country's total emissions. Approximately 30% of heating systems in German homes are over 20 years old, significantly reducing energy efficiency. While the government aims to cut the building sector’s primary energy demand by 80% by 2050, the market remains fragmented. Homeowners often struggle with complex retrofitting processes, disjointed suppliers, and unclear financing options, slowing the adoption of energy-efficient technologies.
