The EPBD Directive (Energy Performance of Buildings Directive) is a European Union directive aimed at improving the energy performance of buildings. Here are some of the key elements of the EPBD Directive:

• Energy performance requirements: The EPBD Directive establishes minimum energy performance requirements for buildings, including new and existing buildings, with the aim of reducing energy consumption and greenhouse gas emissions.
• Energy certification: The Directive requires member states to establish a system of energy certification for buildings, providing information on their energy performance to owners, tenants, and potential buyers.
• Regular inspections: Member states are required to ensure that regular inspections are carried out for heating and air conditioning systems, with the aim of improving energy efficiency and reducing energy consumption.
• Smart technologies: The Directive promotes the use of smart technologies, including building automation and control systems, to optimize energy performance and improve indoor comfort.
• Nearly zero-energy buildings: The Directive requires member states to set a target for all new buildings to be nearly zero-energy by the end of 2020, and by the end of 2018 for public buildings.
• Renovation: The Directive encourages the renovation of existing buildings to improve energy efficiency and reduce energy consumption, and requires member states to establish long-term renovation strategies.
• Training and certification: The Directive requires member states to establish training and certification schemes for professionals involved in the design, construction, and inspection of buildings, with the aim of promoting energy-efficient building practices.
• Information and awareness-raising: The Directive requires member states to provide information and awareness-raising campaigns for building owners, occupants, and the general public, with the aim of promoting energy-efficient building practices and technologies.
