Lighting Retrofit Survey and ROI Analysis

Energy bills don’t shrink by guesswork. On-site assessments map every operational fixture, log circuit-level kWh, and benchmark lux performance against task standards before a single luminaire is specified. Replacement scenarios are then modelled in Dialux, controls layers cost separately, and the savings translated into a defensible business case that finance, facilities, and sustainability teams can underwrite together. The output gives capex committees a clear answer to one question: what does this retrofit return, how fast, and under what assumptions, with every figure traceable to verified data rather than supplier optimism or catalogue marketing claims.

• Calibrated, IPMVP-aligned measurement, not estimated readings
• Dialux simulations checked against EN 12464 task standards
• Transparent lighting ROI analysis with NPV, IRR, and payback figures tied to DEWA tariffs
