Value

  • As LED lighting fixtures are the most energy efficient type of lighting, replacing building fixtures with LED lighting can significantly reduce operational costs and energy use
  • Converting to LED lighting has the added benefit of reducing mercury-containing lighting in the building which reduces health risks for occupants and building staff

Description

Lighting represents a significant percentage of electricity end use and contributes to electrical demand (kW) in addition to consumption (kWh).

Reduction of lighting energy consumption can reduce electricity consumption and costs, lower impact on the electrical grid, assist with ensuring there is sufficient capacity for building electrification or EV charging and reduce carbon emissions associated with electricity, particularly where the electrical grid has a high emission factor.

Optimization can be achieved through efficient fixtures and enhanced controls while also maintaining occupant safety.
