Energy certificate data to characterise the building stock

To create target-oriented, adequate and efficient climate policy instruments, it is essential to have an effective and efficient monitoring of the building stock. This is currently not available, as the existing data on the residential and, in particular, the non-residential building stock is very limited. In order to close these data gaps, energy performance certificates (EA) are often suggested as a possible data source, as they are available almost everywhere in Germany.

So far, however, it has not been determined which concrete and relevant findings can actually be obtained from existing EA. In this project, the data quality and the resilience of the EA data stock will be investigated. In addition, it will be shown how suitable this data is for drawing conclusions about the condition of the German building stock and for analysing the design and impact of energy and climate policy instruments.

The obtained knowledge will be evaluated in regard to its applicability for the design of policy instruments and their monitoring.

Reference projects

Low-temperature district heating networks, or how to use the full potential of district heating

Renewable energies and waste heat sources are to replace the coal and natural gas sources that have dominated Polish district heating networks up to now.

First and foremost, this requires a reduction of the system temperature. The study shows the technical, regulatory and organisational measures required to achieve this
and determines the overall potential for decarbonising district heating in Poland.
