BUILD UP: The European portal for energy efficiency in buildings (Website)

This website serves as a forum for the exchange of best working practices and knowledge and the transfer of tools and resources. The BUILD UP initiative was established by the European Commission to support European Union Member States in implementing the Energy Performance of Buildings Directive. For policymakers, it provides resources on the legislation, toolkits, and guidelines produced by other cities, regions, or countries, as well as a way to share expertise with peers.
