On 29.09.2017, the Polish Committee for Standardization withdrew the PN-EN ISO 13790 standard. Energy properties of buildings. Calculation of energy consumption for heating and cooling. This standard has been replaced by a new standard: PN-EN ISO 52016-1: 2017 (English version) Energy useful properties of buildings – Demand for heating and cooling energy, internal temperatures and explicit and latent thermal loads –
Part 1: Calculation procedures.
The new Ordinance of the Minister of Energy of 13.10.2017 on energy efficiency audits also applies (Journal of Laws of 2017, item 1912).
