15 Ways to make energy efficient lighting easy

  • 15 icons header img

We developed our ‘15 ways to make energy efficient lighting easy’ framework in 2012 as part of eControl and the Thorn Energy Partnership. It now forms a major pillar of our consultation advice for customers who set out to minimise energy consumption.

The framework is based on the principles that implementing one or more of the following guidelines will help generate significant energy savings.

Lamp   1. Lamp efficacy– Ensuring the lamp efficiently converts electricity into light (lm/W).
Ballast classification   2. Ballast classification –Controlling the electricity supply to the lamp (Energy Efficiency Index).
Luminaire distribution   3. Luminaire distribution– Controlling light emission using optics which bend and shape the light to the correct location.
System Efficacy   4. System efficacy– Combining optical and thermal control within the luminaire (luminaire lm/W).
Presence / absence detection   5. Presence/absence detection – Providing lighting only when it's needed.
Daylight   6. Daylight detection – Reducing waste light during daylight hours.
Constant illuminance   7. Constant illuminance –Producing the correct lighting levels for the duration of the maintenance period.
Task-Scene Setting   8. Task-scene setting –Allowing the user to set scenes and adapt the lighting to different tasks.
Timed Off   9. Timed off –Automatic cut-off to turn all lights off during unoccupied hours.
Task Lighting   10. Task lighting –Lighting task areas with the correct amount of light.
Zoning of Light   11. Zoning of lighting –Zoning lighting in accordance to occupancy patterns or window location.
Maintenance Schedule   12. Maintenance schedule –Tailoring maintenance schedules in accordance to product age, performance and environment.
Waste Light   13. Waste light –Eliminating waste light which does not hit the intended target.
Reflectance   14. Reflectance –Taking advantage of light which is reflected from the surface within the space.
Visible Metering   15. Visible smart metering –Enabling results of actions to be quickly seen as increased or decreased energy use to encourage responsible energy consumption.
