In policy terms, the standard for housing insulation (future-proof advice on the degree of insulation of buildings in the context of natural gas-free) is included; a uniform lower limit is indicated for biomass-fired devices that are rated as fully renewable (100 Kw thermal power); policy criteria are inserted to better value the deployment of so-called electrode boilers in heat grids in specific deployments during peaks of renewable electricity generation; finally, it is possible to use values that differ from the flat-rate values in NTA 8800 when applying for an environmental permit (in the BENG calculation).
In addition, there are a number of clarifications, simplifications and substantive changes to NTA 8800:2023.
Articles I to IV may contain technical requirements. Article 1.3 of the Building Decree 2012 and Article 1.3 of the Environmental Regulation also include a provision for mutual recognition.
