Revision of the EU Energy Performance of Buildings Directive

Energy Performance of Buildings Directive featured image

At the beginning of May, the European Union published a comprehensive revision of its Energy Performance of Buildings Directive (EPBD), establishing specific requirements and targets for the energy efficiency and intelligence of buildings across the EU. These regulations apply to both residential and non-residential buildings.

In the EU, new buildings are transitioning to zero-emission structures, prohibiting onsite carbon emissions from fossil fuels. From January 2028, this requirement applies to new public buildings, extending to all new buildings by January 2030. Additionally, each member state will establish a national database for building energy performance.

IBC have complied some resources and information that may be useful to specifiers and installers of BMS and field devices in commercial HVAC systems such as SIs, BMS Engineers, Mechcahnical and Electrical Engineers, HVAC Technicians etc. There is resources available below from the Sustainable Energy Authority of Ireland (SEAI) and the European Building Automation Controls Association (EU.BAC).

Regulations Offer Opportunity

The regulations offer opportunities within buildings where energy usage is not fully visible. With current technologies, it has become more feasible than ever for existing buildings to install such systems.

Typical benefits of this intervention include:

  • Limited disruption to buildings and operations
  • High cost-to-savings ratio
  • Ability to identify high energy uses
  • Ongoing identification of malfunctioning equipment and controls
  • Data-based prioritisation of other projects
  • Attractive selling point to tenants
  • Evidence to access Green Finance

Key changes from the European Association for Building Automation (EU.BAC)

These revised requirements have a focus on building technology. The most important changes are as follows:

1. Extended Requirements for Building Automation and Control Systems (BACS)

  • Non-residential buildings must install BACS for systems with a rated output of 70 kW or more (down from 290 kW).
  • From May 2026, new and extensively renovated residential buildings must incorporate mandatory building automation functions.
  • Non-residential buildings must also have automatic, adequately zoned lighting controls with occupancy detection.

2. Indoor Environmental Quality (IEQ)

  • The EPBD now sets standards for healthy indoor air quality, requiring member states to implement these standards.
  • Intelligent technologies are crucial for monitoring and reporting indoor air quality, enhancing building Automation functions.

3. Smart Readiness Indicator (SRI)

  • SRI evaluates a building’s technological maturity in user interaction, energy network integration, and management efficiency.
  • By June 2026, the European Commission will report on SRI testing, with a legislative instrument expected by June 2027 for large non-residential buildings.

4. Hydronic Balancing

  • New buildings and those replacing heat or cold generators must introduce self-regulating devices for temperature and hydronic balancing.

All buildings who have an obligation based on the outlined parameters must have these systems installed by the deadline, 31st December 2025. – SEAI

Inspection Obligation with Reporting

Member states must introduce regulations for regular inspections of heating, ventilation, and air conditioning systems over 70 kW, with different requirements based on system size:
– Systems over 290 kW: inspected at least every three years.
– Systems over 70 kW: inspected at least every five years.

Inspections assess system efficiency, dimensioning, temperature settings adjustments, fossil fuel reduction, and renewable energy utilization. Buildings with automation or contractually agreed efficiency targets are exempt. After inspection, a report with recommendations must be uploaded to the national energy efficiency database.

BACS Compliance Resources from SEAI and EU.BAC

Get the process started with the SEAI BACS series of factsheets, including their compliance assessment guide.

The initial assessment (steps 1-2 below) which focuses on assessing the system capacities, can be carried out by the building owner or a representative of the building owner who is competent to carry out this assessment. – SEAI

EU.COM experts have reviewed and updated its BACS compliance verification checklist to align with the revised 2024 Energy Performance of Buildings Directive.
