Lighting accounts for 12–18% of household energy in typical KW homes. The right specs cut this by 75–85%, saving $200–$450/year. Here's the energy-efficient lighting stack.
LED Efficiency
LED at 9–14W replaces 60–75W incandescent. 80–88% energy reduction per fixture. Whole-home LED conversion: $300–$800 in bulbs/fixtures; pays back in 12–24 months.
Smart Controls
Motion sensors: 30–45% additional savings on bathroom/closet/utility lighting. Dimmer switches: 20–30% savings on dimmable circuits. Schedule-based lighting: matches occupancy to lighting use.
Daylighting
Sun tunnels (Solatube): $400–$800/install. Reduce daytime artificial lighting by 60–90% in interior rooms during daylight hours.
Frequently Asked Questions
How much can lighting energy upgrades save in KW?
Whole-home LED + smart controls: $200–$450/year savings in Waterloo Region rates. Payback in 18–30 months including hardware costs.
Are motion sensors worth it for residential lighting?
Yes for bathrooms, closets, utility rooms, and entry/laundry. Saves 30–45% on those circuits. Less worthwhile for living rooms (extended occupancy).
How long do LED fixtures actually last?
25,000–50,000 hour rated lifespan. Real-world: 15–25 years typical home use. Premium LED (Lutron, GE Cync) often exceeds rated life.
Should I install dimmer switches everywhere?
In main living areas yes. Dimmers reduce energy proportional to dimming level. Plus enable lighting flexibility throughout the day.
Does D&D specify energy-efficient lighting as standard?
Yes — LED bulbs and fixtures standard on every install. Smart switches and motion sensors offered as upgrade options.
