Energetische Sanierung: Handlungsbedarf auf vielen Ebenen

The report analyzes the gap between Germany's current building renovation rates and its goal to reduce primary energy demand by 80% by 2050. Based on a survey of 2,000 households, it identifies barriers across three phases of the renovation process: initial awareness, planning and decision-making, and technical implementation. It argues that while financial incentives from the KfW and tax benefits are crucial, they must be coupled with better information tools, such as detailed heating bills, and improved professional certification for craftsmen to ensure high-quality, comprehensive renovations rather than isolated single measures.

• The German government aims to reduce the primary energy demand of buildings by 80% by 2050, with an interim goal of reducing heat demand by 20% by 2020. To achieve this, the annual rate of energy-efficient renovations must increase from approximately 0.8% to 2%.
• Comprehensive renovations are necessary because at a 2% annual renovation rate, each building will be reached only once by 2050. Currently, many renovations are limited to single measures that provide only minor improvements.
• Energy-efficient renovations are more cost-effective when integrated into general building modernizations. In such cases, energy-related costs drop to about one-third of total costs, aligning more closely with the actual energy cost savings.
• Information instruments are critical for the first phase of the decision process. Detailed heating cost statements, similar to those used in the US and Canada, could lead to energy savings of 1% to 10% by influencing consumer behavior and investment.
• Trust in information sources is a primary factor during the planning phase. Craftsmen are the most trusted source, with 56% of households expressing trust in them.
• Financial support from the Kreditanstalt für Wiederaufbau (KfW) is considered important by half of the surveyed households for implementing comprehensive renovations. Progressive funding that favors comprehensive standards over single measures is essential, as countries that fund both equally see a prevalence of single-measure applications.
• The quality of technical implementation depends on the training and certification of craftsmen. Current assessments suggest that existing education and further training for craftsmen regarding the implementation, coordination, and communication of comprehensive renovations are insufficient.
