EPBD Automatic Lighting Controls: The 2027 and 2029 Test

What Changed — and Why It Matters Now

At XHLWX (led-project-light.com), a Custom Indoor LED Lighting Manufacturer based in China, the EPBD recast presents a specific procurement question: does a non-residential lighting package deliver the occupancy detection and zoning required for the building, or merely include dimmable drivers? Directive (EU) 2024/1275 sets separate requirements for building automation and automatic lighting controls. European specifiers need to distinguish those obligations before fixing equipment schedules, integration responsibilities and commissioning budgets.

The central distinction is in Article 13 of the recast Energy Performance of Buildings Directive. Paragraphs 9 and 10 address building automation and control systems, or BACS.

Paragraph 12 separately addresses automatic lighting controls. A building-management platform should therefore not be accepted as evidence that the lighting requirement has been fulfilled without checking its actual functionality.

Under Article 13(12), Member States must establish requirements, where technically and economically feasible, for qualifying non-residential buildings to have automatic lighting controls:

• By 31 December 2027: for the specified heating, air-conditioning or combined ventilation systems with effective rated output over 290 kW.
• By 31 December 2029: for those systems with effective rated output over 70 kW.

The controls must be suitably zoned and capable of occupancy detection. These thresholds concern the specified building-services systems, not installed lighting wattage.

The provision is not confined to new construction. The primary reference is Directive (EU) 2024/1275, Article 13.

Article 13(9) retains the 31 December 2024 BACS threshold above 290 kW and extends BACS requirements to the above-70 kW category by 31 December 2029, subject to technical and economic feasibility. The earlier BACS deadline must not be confused with the separate 2027 lighting-control deadline.

Article 35(1) establishes 29 May 2026 as the general transposition deadline for the relevant recast provisions. Because the EPBD is a directive implemented through national measures, buyers must check the applicable Member State’s legislation, assessment procedures and enforcement arrangements rather than treat the EU text as a complete installation specification.

The Technical Detail Behind the Headline

Article 13(12) specifies a functional outcome, not a compulsory communications protocol. It does not prescribe DALI-2, Casambi or 0-10V, nor does it establish a universal office illuminance or glare limit. The design task is to connect the required occupancy-responsive zoning with suitable lighting quality, equipment compatibility and documented operation.

The following schedule is an illustrative office tender baseline, not an XHLWX product declaration or a list of values mandated by the EPBD. Final selections require project calculations and supplier evidence.

Need the DIALux evo file or IES / LDT data for this setup?Get lighting files →

Request IES and LDT photometric files corresponding to the quoted optic, output and mounting arrangement. Use them in DIALux to assess maintained illuminance, uniformity and glare. A photometric calculation supports visual-performance verification; it does not prove that a sensor detects seated occupants or that a gateway exposes the required operating states.

For the control package, specify behaviour before protocol. An example design target could use separate perimeter and interior zones, a 15-minute vacancy delay, and a defined manual override.

None of those particular settings is a universal EPBD requirement. They are commissioning parameters that the design team must justify against occupancy patterns, safety requirements and the national implementation.

What This Means for Specifiers and Buyers

How Should a Contractor Determine Whether the 2027 or 2029 Deadline Applies?

Start with the mechanical-services schedule, not the lighting bill of quantities. Ask the building-services engineer to document the relevant heating, air-conditioning and combined-system capacities, then obtain a jurisdiction-specific determination of how the national rules apply to that installation. Do not independently add unrelated nameplate values without checking the assessment method.

As a simplified illustration, a building with a qualifying 320 kW heating system falls above the 290 kW threshold, even if its lighting load is only 12 kW. A qualifying 90 kW system falls above 70 kW but below 290 kW. These examples illustrate the EU thresholds; they do not replace a building-level applicability assessment.

The wording is “over”, not “at least”: exactly 70 kW is not above 70 kW under that threshold wording. However, national measures may impose additional requirements. Record the selected compliance route and any technical or economic feasibility assessment before tender, including who has authority to accept it.

What Must a Lighting Tender Include Beyond Dimmable LED Drivers?

A dimmable driver is only one component of an automatic lighting-control system. The tender should separately identify sensors, application controllers, interfaces, power supplies where required, commissioning software and configuration access. Assign responsibility for each connection between lighting, electrical installation and building automation.

Define zones on a drawing and issue a sequence-of-operation schedule. For each zone, state the occupancy input, permitted output states, delay settings, override behaviour and response after power restoration. A single sensor controlling an entire floor needs a documented justification; the EPBD’s requirement for suitable zoning should not be reduced to a token sensor on a large circuit.

For DALI-2 designs, verify the certification status and function of the specified devices rather than accepting a generic “DALI compatible” description. For Casambi designs, identify the exact ecosystem-compatible components and project configuration access.

For 0-10V designs, document switching arrangements, minimum dimming behaviour and any separate route needed for status reporting. The EPBD itself does not choose among these architectures.

How Can Lighting Controls Support BACS Without Confusing the Two Obligations?

Article 13(10) requires BACS capabilities including continuous monitoring, logging, analysis and adjustment of energy use; efficiency benchmarking and detection of efficiency losses; and communication and interoperability with connected technical building systems. It also includes indoor environmental quality monitoring from 29 May 2026.

Those requirements go beyond an occupancy sensor switching a lighting circuit. Conversely, a BACS dashboard does not establish that automatic lighting controls are suitably zoned. The procurement documents should therefore contain two linked acceptance schedules: one for lighting operation and one for the building-level automation functions applicable to the project.

Where integration is specified, define the point list and gateway boundary. Useful project targets include occupancy state, commanded output, override state and equipment faults where supported.

Identify which values are measured and which are inferred. A 50% dimming command, for example, must not automatically be reported as a measured 50% reduction in electrical consumption.

For US-based specifiers delivering European projects, the immediate action is to appoint a responsible EU compliance lead. For projects located in the United States, EPBD deadlines do not apply merely because the same luminaire is purchased; applicable state or local energy codes, electrical rules and product-acceptance requirements remain the starting point.

Compliance Checklist (IES / LDT / DIALux / CE / RoHS / ErP)

Use the following checks as a tender and handover framework. They separate building-level legal obligations from product conformity and engineering acceptance.

1. Establish the legal scope. Record the country, building use, relevant system outputs and applicable national implementation of Article 13(9)–(12). Identify the responsible assessor and any feasibility determination. Do not accept a supplier’s generic “EPBD compliant” label as the whole assessment.

2. Freeze the photometric configuration. Obtain IES and LDT photometric files for the exact selected luminaire. Record the optic, lumen output, input power, CCT and mounting details. Require review if substitutions change those parameters.

3. Keep the DIALux calculation reproducible. Save the room geometry, reflectances, calculation planes and maintenance factor. For the illustrative office schedule, test the 500 lux and UGR ≤19 targets in the actual layout rather than treating glare as an unconditional luminaire rating.

4. Check CE documentation by applicable legislation. Identify the relevant requirements, including the Low Voltage Directive 2014/35/EU, EMC Directive 2014/30/EU, or the Radio Equipment Directive for radio-enabled equipment as applicable. CE marking does not demonstrate successful building-controls commissioning.

5. Check RoHS and ErP separately. Review evidence under Directive 2011/65/EU, as amended, and establish the applicable light-source and control-gear obligations under Regulation (EU) 2019/2020, as amended. Avoid assuming that an entire luminaire and every component share an identical regulatory classification.

6. Witness operation before handover. Test occupied and vacant states, zone boundaries, manual override, power recovery and interface failures. Check that normal-lighting automation does not compromise the approved emergency-lighting strategy. Deliver drawings, settings, configuration backups, access credentials and a signed record of unresolved defects.

Frequently Asked Questions

Q: Does the EPBD Require Automatic Lighting Controls in Every Commercial Building by 2027?

No. Article 13(12) sets a 31 December 2027 deadline for qualifying non-residential buildings above the 290 kW threshold and a 31 December 2029 deadline above 70 kW, subject to technical and economic feasibility. These are specified heating and air-conditioning system thresholds, not lighting loads. National implementing legislation determines the applicable assessment and enforcement arrangements.

Q: Does Specifying DALI-2 Automatically Satisfy the EPBD Lighting Requirement?

No. DALI-2 identifies a control technology and certification framework, not completed building compliance. Article 13(12) requires automatic lighting controls that are suitably zoned and capable of occupancy detection. A project still needs appropriate sensors, configured control logic and verification. Even a fully addressable installation can miss the intended outcome if occupancy inputs or zone settings are absent.

Q: Can Existing Luminaires Remain When Automatic Lighting Controls Are Added?

Potentially, provided the retained equipment supports the approved control strategy and applicable safety and performance requirements. A retrofit assessment should test driver compatibility, switching behaviour and sensor coverage. For example, a 0-10V installation may require separate switching arrangements depending on the driver. Article 13(12) establishes a control outcome, not a blanket requirement to replace every luminaire.

Q: What Evidence Should a Contractor Provide at Practical Completion?

Provide the applicability assessment, zone drawings, equipment schedule, configuration backups and witnessed functional-test results. Include the relevant declarations and photometric calculations. For a project using a 15-minute vacancy delay, record that setting and demonstrate the resulting operation. Where BACS integration is required, verify the agreed data points and distinguish measured consumption from estimated or commanded values.
