A building-energy calculation and a restricted-substance declaration answer different questions. Keep them separate in the tender so the supplier knows what evidence is required for each.
Identify the energy-assessment method
EN 15193 provides methods for assessing lighting energy use in buildings. Confirm the edition, calculation method, and inputs required by the project. Do not describe it as a universal customs certificate for a smart luminaire.
Document the installed system
An energy assessment needs the installed load, operating schedule, controls, and other relevant assumptions. A component datasheet cannot establish the annual energy use of a whole building.
Check RoHS for the product supplied
RoHS concerns restricted substances in electrical and electronic equipment. Review the applicable scope, substance limits, exemptions, and supporting technical evidence. Do not assume a restriction is newly introduced because it appears in a recent supplier summary.
Match each limit to its source
Ask for the regulation or standard, edition, product category, and test conditions behind a claim. Power quality, energy use, and restricted substances should not be merged into one unexplained pass/fail table.
Track component changes
Keep the bill of materials and supplier declarations tied to the model revision. A driver, cable, solder, or enclosure substitution may need a new evidence review.
Prepare two clear documentation sets
Keep the building calculation and commissioning records with the project design. Keep model-specific product declarations, test evidence, and component records with the product technical file.
Frequently Asked Questions
Does RoHS establish a lighting system’s energy efficiency?
No. It addresses restricted substances; energy performance requires different evidence.
Is a component declaration enough for the finished product?
The responsible manufacturer or importer must assess the finished product and retain the evidence required for it.
