The European Commission provides on its website a wide range of resources and information related to the implementation of the Energy Performance of Buildings Directive (EPBD) and other initiatives to improve energy efficiency and reduce greenhouse gas emissions in the building sector. 

These resources include detailed information, key facts, a legislative timeline, and links to relevant documents for further study. These include the revised Directive itself, which was published in the Official Journal. 

These resources are useful to better understand the policies, initiatives and actions underway at European level to address the challenges related to energy efficiency in buildings and the transition to a low-carbon economy.
