The delegated regulation is applicable since 1 January 2016 and is binding in all parts and directly and immediately valid in all Member States and has an impact on the calculation of high efficiency verification.
The news section of the BHKW-Infozentrum informs in detail in the report "New efficiency reference values for high-efficiency criteria “in which cases high efficiency verification is required, what specific changes have to be made and what impact this has. (https://www.bhkw-infozentrum.de/...)
