2.3.1 Lighting

Course subject(s) 2. Electricity use in buildings

In this video we move on to looking at the development of electricity use for lighting in buildings. Again we will explore the impact of energy efficiency improvements, but we will now also look at how smart lighting can help to reduce energy consumption.

Key takeaways:

  1. Electricity demand for lighting can be reduced by technical options to improve efficiency, options to reduce the time of lighting use (e.g. presence control) and finally by options to promote good habits (e.g. turning lights off when leaving a room)
  2. LED technology is rapidly dominating the lighting market largely as a result of its significantly better energy efficiency
  3. Smart lighting – energy-efficient LEDs combined with smart sensors that can detect presence and the amount of daylight offer an opportunity to make substantial energy savings
