Key Terms
- Zero-emission building
- A building with very high energy performance, zero on-site carbon emissions from fossil fuels, and total primary energy covered by renewable or carbon-free sources [Art. 2(2), Art. 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 renewable sources [Art. 2(3)].
- Minimum energy performance standards (MEPS)
- Mandatory thresholds expressed in kWh/(m2.y) that existing buildings must not exceed by specified deadlines, targeting the worst-performing segments of the building stock [Art. 9].
- Energy performance certificate (EPC)
- A certificate issued by a qualified expert indicating the energy performance of a building on an A-to-G scale, required for sale, rental, and advertising [Art. 19].
- Major renovation
- Renovation where the total cost exceeds 25% of the building value (excluding land), or where more than 25% of the building envelope surface is renovated [Art. 2(22)].
- Deep renovation
- A renovation that transforms a building into a nearly zero-energy building (before 2030) or a zero-emission building (from 2030 onward) [Art. 2(20)].
- Renovation passport
- A digital document providing a tailored roadmap for staged deep renovation of an individual building toward zero-emission status, issued after an on-site visit by a qualified expert [Art. 12].
- Smart readiness indicator
- A rating of a building's capability to adapt its operation to occupant needs, optimise energy use, and interact with the energy grid [Art. 15, Annex IV].
- Building automation and control system (BACS)
- A system comprising all products, software and engineering services for automatic control, monitoring and optimisation of building technical systems [Art. 2(41)].
- Life-cycle global warming potential (GWP)
- The cumulative greenhouse gas emissions of a building over its entire life cycle, calculated according to Annex III and mandatory for disclosure in new buildings from 2028/2030 [Art. 7(2)].
