Nearly-zero-energy buildings are characterized by very low energy requirements, with a considerable share of these requirements covered by renewable energy sources, either on-site or close by. This standard can be met either through stricter specifications for the building shell (very low heating requirements) or through increased renewable energy sources. The European nearly-zero-energy building standard is being introduced step by step for all new buildings in Vienna, as it applies to all new public buildings since 2018 and all buildings from 2020.
