The Energy Efficiency Act distinguishes between buildings, processes and transport. Those areas whose share of the total energy consumption of the company is higher than 10% must be taken into account in the audit. The areas to be audited were based on the 2015 audit. Based on the requirements of Section 9 of the Federal Energy Efficiency Act (EEffG) for the building sector, the Vienna headquarters are to be audited, as well as representative residential complexes in Vienna and Lower Austria. The existing vehicle fleet must be audited for the transport sector.
