Informationsinstrumente zur Förderung von Energieeinsparungen im Wohngebäudebestand

The report evaluates information tools used to encourage residential energy retrofits, categorizing them by the stage of the decision-making process they target: creating awareness, assisting in planning, and supporting professional implementation. It finds that while individual tools like detailed billing or energy audits can trigger savings, their effectiveness often depends on implementation design, such as 'opt-out' participation and the communication skills of professionals. The document highlights that in Germany, the government aims to reduce buildings' primary energy demand for thermal use by 80% by 2050, requiring a significant increase in the annual retrofit rate.

• The German government's goal to reduce primary energy demand for thermal use in buildings by 80% by 2050 (relative to 2008) requires the annual rate of thermal efficiency retrofits to increase from approximately 0.8% to 2%.
• Detailed energy bills and reports containing normative data (such as local averages) are cost-effective and can lead to energy savings between 1% and 10%. Effectiveness is higher when participation is automated via an 'opt-out' system rather than requiring an 'opt-in' subscription.
• In-home energy displays and smart meters can lead to electricity savings of around 5% for large samples of regular users, though some motivated individuals may achieve 20% or more. Success depends heavily on accompanying information campaigns and user education.
• Local leadership programs leveraging peer communication (neighbors and friends) are an efficient, low-cost way to deliver advice. In Finland, the Energy Environment Experts programme's direct savings through 2010 were estimated at 14% of the total CO2 emission saving requirement of the Energy Saving and Efficiency Program.
• Energy Performance Certificates (EPCs) generally have a moderate to low impact on purchasing and retrofit decisions. While they are among the most trusted sources relative to others, they often fail to translate energy ratings into the financial implications that homeowners prioritize most.
• Online energy analysis tools are highly popular and cost-effective, with some German tools like 'Heizcheck' acting as a principal trigger for 25% of retrofits among owners who used the tool. However, a wide range of results exists between different software tools, and many lack programming documentation.
• Energy auditing and consultation are effective for triggering measures; for example, over 90% of users of the detailed 'BAfA-Vor-Ort-Beratung' program in Germany implemented or planned energy saving measures. The impact is influenced not only by technical expertise but also by how the results are communicated.
• Professional certification for contractors helps households build trust and select suitable experts, but the process can be a burden for the small companies that make up 92% of EU construction firms. Linking certification to subsidy schemes or building codes is recommended to increase market penetration.
