Energy renovation rates in the building sector
Various federal and cantonal energy and climate policy measures aim to significantly increase the rate of energy-efficient building renovations, also known as the energy renovation rate. In this context and for other energy and climate policy reasons, the question arises as to how the energy renovation rate has developed in recent years and how high it currently is. Knowledge of past and current renovation rates is important for assessing the impact of measures in the areas of energy efficiency and CO2 emissions. With the help of the renewal rates and a well-structured quantity structure of the building stock, the development of energy demand and CO2 emissions can be traced.
Because representative data on energy renovation is not regularly collected and because around ten years have passed since the last surveys and the synthesis of the results, sample surveys and basic research were carried out again from 2020. This was done in connection with the Federal Office of Energy's MISTEE research project and the cantons' reporting on CO2 emissions in the building sector. Twenty cantons were covered and the sample size comprised almost 12,000 responses from building owners who provided information on the measures implemented over the last thirty years in the area of building envelopes and heating systems.
The results of this report serve as a basis for the federal government to further develop its measures for energy-efficient building renovation.
