The EU Energy Performance of Buildings Directive, met with measured data
The Energy Performance of Buildings Directive (EPBD) is the EU law that drives building energy performance through certificates, minimum performance standards, renovation and building automation requirements. Member states transpose it into national law. Aqueduct supplies the monitoring side: continuous energy data, benchmarking, efficiency loss detection and indoor environment records that building automation and control provisions describe.
What the EPBD is and who it applies to
The EPBD is the European Union's main law on the energy performance of buildings. It was recast in 2024 with the aim of a zero-emission building stock. It covers energy performance certificates, minimum energy performance standards for the worst performing non-residential buildings, national renovation plans, zero-emission requirements for new buildings, solar readiness, electric vehicle infrastructure and building automation and control systems. As a directive, it is transposed into national law, so the detailed obligations, thresholds and deadlines differ by member state.
For operators of larger non-residential buildings, the building automation and control provisions matter most day to day. They describe systems capable of continuously monitoring, logging, analyzing and adjusting energy use, benchmarking efficiency, detecting losses of efficiency in technical building systems, informing the facility manager and communicating with connected systems. The recast also gives weight to indoor environmental quality. Check your national transposition and the current text for thresholds and dates.
EPBD provisions and the evidence Aqueduct supplies
Aqueduct supplies monitoring, analytics and records. National authorities, assessors and your engineers judge compliance.
| Requirement | Evidence needed | How Aqueduct supplies it |
|---|---|---|
| Continuous monitoring and logging | Energy use recorded continuously, not only from bills | Electricity, gas and thermal meters read continuously and stored per site, floor and zone |
| Analysis and adjustment | Ability to analyze use and adjust it | Load disaggregation and anomaly detection, with setpoint and schedule changes where control is enabled, with owner approval |
| Benchmarking | Efficiency compared over time and against similar buildings | EUI and weather-normalized benchmarks across a portfolio, per building and per system |
| Detecting losses of efficiency | Identification of technical systems losing efficiency | Fault detection on HVAC and plant, such as simultaneous heating and cooling or economizer faults |
| Informing the facility manager | Notifications about improvement opportunities | Plain language alerts routed to the responsible person and your CMMS |
| Interoperability | Communication with connected technical building systems | BACnet, Modbus, M-Bus, MQTT and LoRaWAN integrations on one data layer |
| Indoor environmental quality | Monitoring of indoor conditions where required | CO2, temperature, humidity and other parameters per zone from AirSafe |
| Energy performance certificates and MEPS | Data for certificates and minimum performance tracking | Measured consumption and EUI by building to support assessors and renovation planning |
How to prepare for EPBD obligations
Read your national transposition
Find which buildings, thresholds and dates apply in each country where you hold buildings.
Inventory systems and meters
List technical building systems, their rated output and how they are monitored today, building by building.
Close the monitoring gaps
Add metering and integrations so energy use is logged continuously, using wireless devices where wiring is costly.
Turn on analytics
Use benchmarking and fault detection so efficiency losses are found and reported to the facility manager.
Plan improvements on measured data
Use measured baselines to plan renovation steps toward minimum performance standards and certificates.
What stays with you and national authorities
The EPBD is implemented through national law. Aqueduct supplies systems and data.
Energy performance certificates
Certificates are issued by qualified assessors under national schemes.
Renovation decisions
Envelope, heating system and renovation choices are made by owners and their designers.
Compliance decisions
National authorities enforce the rules. Aqueduct does not certify compliance.

Common questions
The Energy Performance of Buildings Directive is the EU law on building energy performance, recast in 2024. It covers certificates, minimum performance standards, renovation, zero-emission buildings and building automation. Member states transpose it into national law.
The directive requires certain non-residential buildings to have building automation and control systems that can monitor, log, analyze and adjust energy use, benchmark efficiency and detect efficiency losses. Thresholds and dates are set in national law, so check your country.
Aqueduct provides the monitoring, analysis, benchmarking and alerting functions, and control where it is enabled with owner approval. Whether a setup satisfies national rules is for your engineer and the authority to judge.
The recast gives weight to indoor environmental quality, including monitoring in some cases. National rules set the detail. Aqueduct monitors CO2, temperature, humidity and other parameters per zone.
Yes. Aqueduct reads existing BMS points over BACnet or Modbus and adds wireless metering where gaps exist.
It is an EU scheme to rate how ready a building is to use smart technologies. It is optional in most member states. Measured data from Aqueduct can inform an assessment.
No. Certificates are issued by qualified assessors under national schemes. Aqueduct supplies measured consumption that helps explain and improve the rating.
