Introduction
EU energy policy is increasingly clear: modern buildings must not only measure energy use, but also understand it, compare it, and actively improve it. The recast ** Energy Performance of Buildings Directive (Directive (EU) 2024/1275) ** establishes upgraded requirements for Building Automation and Control Systems (BACS), with key deadlines in December 2024, May 2026, and December 2029.
What The EPBD Requires
For certain non-residential buildings, EU rules now require the installation of a Building Automation and Control System (BACS), particularly where systems are large enough to matter and where doing so is technically and economically feasible:
- Buildings with heating or air-conditioning systems over 290 kW must be equipped with BACS by 31 December 2024
- This requirement expands to non-residential buildings with systems over 70 kW by 31 December 2029 The Directive defines BACS broadly as a system comprising products, software, and engineering services enabling efficient, economical, and safe operation of technical building systems. Most importantly, the required BACS capabilities can be summarized in three core outcomes:
- Continuous monitoring, logging, analysis, and the ability to adjust energy use
- Benchmarking performance, detecting efficiency losses, and informing responsible people with improvement opportunities
- Interoperability communication across technical systems from different manufacturers and protocols Additionally, from 29 May 2026, BACS must be capable of monitoring indoor environmental quality (IEQ) including air quality, thermal comfort, and lighting conditions—to ensure healthy indoor environments alongside energy efficiency.
Where Enectiva Fits
Enectiva is designed to connect energy data, building technology, and decision-making into one platform supporting industrial sites, commercial portfolios, and residential properties (including multi-site and mixed-use environments). Below is how Enectiva aligns with the EPBD’s functional requirements.
- Continuous Monitoring, Logging, And Analysis
- High-granularity data capture is the foundation of “continuous monitoring.” Enectiva supports readings from monthly/manual entries through automated readings down to very short intervals for critical meters, allowing organizations to monitor consumption patterns as closely as their use case requires.
- Hardware independence is equally important: Enectiva can collect data via multiple protocols (including M-Bus, Modbus, WM bus, BACnet, pulses/S0) and transmit via fixed, mobile, and IoT networks.
- Analysis becomes actionable when it can be linked to context. Enectiva supports capturing “energy events” (e.g., equipment replacement or insulation upgrades) so teams can see how changes impact consumption and costs over time.
- Benchmarking, Loss Detection, And Informing Responsible Teams The EPBD expects that the system doesn’t just collect data, it helps identify losses and informs the people who can act. Enectiva supports this workflow with:
- Dashboards and portfolio visibility (consumption, water, gas, and more) to establish baselines and track trends.
- Automated notifications (email/SMS) for consumption and cost thresholds—helpful for early detection of abnormal operation or budget overruns.
- Benchmark-ready data inputs, including integration of external drivers (such as weather station data or occupancy/production parameters) that make comparisons more meaningful. This combination supports the Directive’s requirement to benchmark efficiency, detect losses, and inform the person responsible about improvement opportunities.
- Interoperability Across Systems And Manufacturers A core EPBD requirement is interoperability—buildings rarely have “one vendor, one protocol.” Enectiva supports interoperability through:
- Multi-protocol data acquisition (including BACnet and Modbus)
- A REST API to integrate with company systems, accounting/ERP, and measurement & regulation / BMS systems
- Support for building management systems to send meter readings directly to Enectiva, enabling multi-vendor environments.
Industrial, Commercial, And Residential Use Cases
While the EPBD’s BACS requirement for non-residential >290 kW systems applied from 31 December 2024, the Directive also introduces functionality that applies to residential buildings from 29 May 2026 (continuous monitoring, efficiency drop alerts, and effective controls for new buildings and those undergoing major renovation). That makes Enectiva’s monitoring + alerts + integration approach relevant across:
- Industrial: sub-metering for production lines, utilities, compressed air, and process heat
- Commercial: multi-site portfolios (offices, retail, logistics), cost control, performance reporting
- Residential: apartment blocks and shared systems, transparency for owners/managers, abnormal consumption alerts
Implementation Note
Compliance is not just “software installed”—it depends on how the system is configured, what meters/controllers are connected, and how reporting/alerts are set up for responsible roles. For EPBD alignment, the best practice is to document:
- Connected Meters and Technical Systems
- Data Granularity and Retention
- Benchmarks and Alert Thresholds
- Reporting Routines and Responsible Recipients
- IEQ Monitoring Capabilities (air quality, temperature, humidity, lighting sensors and reporting—from 29 May 2026)

Conclusion
The recast EPBD makes clear that building automation is no longer optional for larger non-residential buildings, and the requirements will only widen as the 70 kW threshold takes effect in 2029 and indoor environmental quality monitoring becomes mandatory from May 2026. Meeting these requirements is less about installing a single piece of hardware and more about having continuous, granular visibility into how a building consumes energy, the ability to benchmark that performance and flag losses, and the interoperability to bring data together from different meters, controllers, and protocols. Enectiva is built around exactly that combination of monitoring, benchmarking, and integration. While it does not replace the physical controllers and sensors that make up a complete BACS installation, it can serve as the software layer that turns connected building systems into the kind of actionable, EPBD-aligned insight the Directive is designed to require — across industrial, commercial, and residential portfolios alike. For building owners and operators working toward the 2024, 2026, and 2029 deadlines, the practical starting point is the same regardless of building type: know what is connected, know what is being measured, and make sure that information reaches the people who can act on it.
