Key Terms
- Zero-emission building
- A building with very high energy performance where the very low amount of energy still required is fully covered by energy from renewable sources generated on-site, from a renewable energy community, or from a district heating and cooling system, as defined in Article 11.
- Nearly zero-energy building (NZEB)
- A building with very high energy performance where the nearly zero or very low amount of energy required is covered to a very significant extent by energy from renewable sources. The NZEB standard is the interim requirement until the zero-emission standard applies [Art. 2(2)].
- Energy performance certificate (EPC)
- A certificate recognised by a Member State or a legal person designated by it, which indicates the energy performance of a building or building unit calculated according to the methodology adopted pursuant to Article 4 [Art. 2(15)].
- Minimum energy performance standard (MEPS)
- A regulatory threshold requiring buildings with the worst energy performance in national stock to be renovated to a defined level within a set deadline, applied per Article 9 to the worst-performing 16 % and 26 % of non-residential buildings.
- Life-cycle global warming potential (GWP)
- An indicator measuring the total greenhouse gas emissions over a building's entire life cycle — from raw material extraction through construction, use, and end-of-life — expressed in kg CO2-equivalent per m2 of useful floor area over a 50-year reference study period [Art. 7, Annex III as amended by 32026R0052].
- Major renovation
- The renovation of a building where the total cost of the renovation relating to the building envelope or the technical building systems exceeds 25 % of the value of the building (excluding land value) or more than 25 % of the surface of the building envelope undergoes renovation [Art. 2(19)].
- Building automation and control system (BACS)
- A system comprising all products, software and engineering services that can support energy-efficient, economical and safe operation of technical building systems through automatic controls and by facilitating manual management [Art. 2(42)].
- Renovation passport
- A document that provides a tailored roadmap for the renovation of a specific building in a maximum number of steps that will transform it into a zero-emission building by 2050 at the latest [Art. 12].
