OVERVIEW – Selected international Examples of Nearly Zero-Energy Buildings

Directive 2010/31/EU (EPBD) indicates that EU Member States must ensure that by 2021 all new buildings, and already by 2019 all new public buildings, are nearly zero-energy buildings (NZEBs). Article 2 of the EPBD defines the term NZEB as a building with a very high energy performance and a nearly zero or very low amount of energy required, which itself is covered to a very significant extent from renewable sources.

Green Lighthouse: Denmark’s first public carbon-neutral building

​Green Lighthouse is Denmark’s first public carbon-neutral building. The building has been built in less than a year in a close public/private partnership.
It is a round, sculptural building with high ceilings and an open, spacious floorplan. It is designed in a way that reduces energy consumption by 70% utilising renewable energy, natural ventilation and light – and with a highly efficient climate envelope.

IEE project LEAF presents technical toolkit for energy saving measures at apartment blocks in multi-ownership

Energy efficient renovations of apartment blocks in multi-ownership are difficult to realise, mostly because of difficult decision taking and other legal and financial boundaries. The LEAF Technical Toolkit enables organisations to identify and understand appropriate energy improvements for apartment blocks. This includes estimated costs and savings from measures, and potential subsidies. It also contains advice on the impact of resident behaviour, and how energy saving behaviour can be promoted.

The technical toolkit offers guidance on the following topics:
