LED lighting retrofits: measuring ROI for multi-site portfolios

Beyond the rebate packet

LED conversions are often sold on incentives alone. For a portfolio, the durable value is lower wattage, longer service life, and fewer lift rentals—but controls and commissioning determine whether savings persist after year one.

Build a credible business case

• Baseline demand: Use bills and spot metering where helpful; do not guess.
• Include labor: Count relamp truck rolls, lift time, and after-hours disruptions.
• Specify controls: Schedules, sensors, and tuning prevent “LED but still on all night” waste.

Prioritize the portfolio

Start where hours-of-operation are longest, tariffs are high, or maintenance churn is painful. A phased plan with consistent specifications prevents a rainbow of incompatible parts that haunt you for a decade.
