In 2010, EU has established a legislative framework that includes the Energy Performance of Buildings Directive (EPBD) and the Energy Efficiency Directive. Together, the directives promote policies that aim to achieve a highly energy-efficient and decarbonized building stock by 2050, create a stable environment for investment decisions, and enable consumers and businesses to make more informed choices to save energy and money. Following the introduction of energy performance rules in national building codes, buildings today consume only half as much as typical buildings from the 1980s.
As part of the “Clean energy for all Europeans” package, both directives were amended in 2018 and 2019. In particular, the 2018 amendments to EPBD introduced new elements to increase building renovations which is binding for all the EU Member States, and stipulates targets, levels and deadlines for EE improvements. All the member States had to incorporate these amendments into their legal regulatory systems.
