FACT SHEET #12 | QUALICHeCK Study Austria – Assessment of EPC input data based on recalculation and on-site validation

Share this Post:

The QUALICHeCK study Austria investigated the Energy Performance Certificate (EPC) scheme applied for the allocation of energy efficiency subsidies in the region of Salzburg. The scheme is based on the rules and procedures of the building legislation but requires more ambitious energy performance values and a two-step procure, namely the update of the planning EPC submitted at the building permit stage, in order to represent as-built conditions. Twenty-six multi-unit residential buildings, their EPCs and site foreman’s plans, as well as the legal requirements to comply with were analysed, in order to assess the EPC quality and to develop recommendations for improvement.


The study resulted in the conclusion that the two-step procedure is useful and feasible, but that it is necessary to implement a check to verify whether update has actually taken place. Regarding input data for EPC calculation there are several equally compliant options for determining them, which makes control, at the level of input data, very difficult. Federal and regional documents lack clarity and thus offer some undesirable range of interpretation with respect to determining EPC input data. The study points out that EPC experts need to be very well trained to choose the input data correctly. Unfortunately, a certain professional license is sufficient to be an acknowledged EPC expert in Austria, and proof of training is not needed.
