Renovation is an opportunity to review lighting alongside ceilings, electrical work, and building controls. Start with the survey and required outcomes so the lighting order fits the wider project.
Define the building’s renovation scope
Record the spaces being altered, existing electrical and control systems, and performance goals. Confirm which national building-energy requirements apply to the work.
Use the project’s applicable timetable
Check regulatory dates with the designer and local authority. Then work backward from access, tenant moves, procurement, testing, and commissioning. A general EU renovation milestone is not a product delivery deadline.
Clarify any readiness assessment
If the project uses a smart-readiness assessment, establish the applicable method and evidence. Do not assume every building needs the same score, protocol, or connected-device package.
Specify a system that can be maintained
Check driver replacement, sensor access, spares, control ownership, and software support. Coordinate mounting and wiring with the ceiling and other services.
Compare equivalent lighting outcomes
Use the surveyed load and schedule as the baseline. Compare alternatives that meet the same task, glare, and uniformity requirements. Include access labour, controls, disposal, and expected maintenance.
Handover closes the project
Keep drawings, fixture records, test results, final settings, warranty details, and maintenance instructions together. Plan a follow-up visit to adjust sensors and schedules after occupancy.
Frequently Asked Questions
Should every old fixture be replaced one for one?
No. Review the tasks, layout, optics, and controls. The original positions may no longer suit the space.
What makes a savings estimate useful?
A documented baseline, comparable light levels, a realistic schedule, and a complete installed-cost estimate.
