The revised Energy Performance of Buildings Directive (EPBD) published in the Official Journal

The European Union has today published a major revision of its Energy Performance of Buildings Directive (EPBD) in the Official Journal, setting ambitious requirements for energy efficiency and smartness in buildings across the bloc. This is a significant step towards a decarbonised and digitalised building sector in the EU.

Key Changes:

• Expanded Building Automation and Control Systems (BACS) requirements:
  • The scope of mandatory BACS installation in non-residential buildings will be expanded by the end of 2029, reducing the threshold of buildings covered to 70 kW of effective rated output (the existing threshold of 290 kW comes into effect at the end of this year).
  • Mandatory functionalities introduced for new and majorly renovated residential buildings by May 2026.
• Focus on Indoor Environmental Quality (IEQ):
  • For the first time, the EPBD defines and mandates member states to set standards for healthy indoor air quality.
  • Smart technologies are recognised as crucial for effective IEQ monitoring and reporting through the extension of BACS capabilities.
• Smart Readiness Indicator (SRI):
  • The European Commission is to report on the SRI testing by June 2026 and prepare a delegated act mandating SRI application in large non-residential buildings by June 2027
• Hydronic Balancing:
  • New buildings and those replacing their heat or cooling generators must also implement self-regulating temperature controls and hydronic balancing

Benefits and Next Steps:

The revised EPBD marks a significant step towards a smart and efficient building sector across the European Union. These new regulations, with a transposition deadline of May 29th, 2026, for member states, hold immense potential for reducing energy consumption, improving occupant well-being, and paving the way for a green and digital future.

eu.bac is committed to providing comprehensive support to member states in implementing these changes. We are working on developing guidelines, checklists, and studies to equip member states and stakeholders with the necessary knowledge and tools. Through this collaborative effort, the EU can unlock the full potential of the revised EPBD and create a more sustainable built environment for generations to come.
