Before using a deadline to plan a retrofit, establish which national requirements apply to the building. Record its use, system capacities, existing controls, and planned work with the project designer.
Check the requirement for this building
The EPBD framework is implemented through national measures. Verify the building category, relevant system thresholds, timing, exemptions, and technical conditions. Avoid treating one headline date as a requirement for every property.
Translate the rule into control functions
List the required scheduling, occupancy response, daylight control, monitoring, and overrides. Describe the acceptance tests so the installation can be checked against the brief.
Plan for access and replacement
Check whether drivers, light sources, sensors, and communication devices can be serviced. Record spare-part availability and the work needed to reach them. Confirm any applicable product-specific repair requirements separately.
Choose devices for the actual system
Specify driver and controller models, supported functions, and compatibility evidence. DALI-2 or D4i can be relevant to a design, but a protocol label does not replace the building’s functional requirements.
Keep product records in scope
Check energy-label and EPREL obligations for products covered by those rules. Match model identifiers and responsible-operator details to the products supplied.
Build the retrofit sequence
Survey first, trial the proposed system, agree on access and downtime, then procure. Include commissioning, measurement, staff training, and configuration backups in the schedule.
Frequently Asked Questions
Does every existing building face one lighting deadline?
Applicability depends on the national implementation, building, systems, and relevant conditions. Check the project with the responsible designer.
Should a retrofit tender specify a protocol?
Specify required functions and integration first, then the architecture and product evidence needed to deliver them.
