Guidelines & Technical Modules > Key message: Lighting

Lighting has a substantial impact on the energy consumption in non-residential buildings, accounting for up to 1/3 of the electricity used in some office buildings for example. With the help of modern technology, major energy savings can be achieved. Depending on the existing inventory and set-up of the lighting systems in a non-residential buildings, energy savings between 30 and 50 percent may be achieved by improving the existing lighting systems.

The energy efficiency of your lighting systems can be improved in the following steps:

1. Selection of energy efficient lamps

2. Selection of energy connecting devices

3. Improvement of luminaires

4. Energy saving lighting control systems

 5. Introduction / improvement of maintenance procedures

6. Design aspects

Energy savings result from finding an optimum combination of different types of lamps with their specific supporting hardware (such as luminaires and ballasts) and the way the lighting systems is applied in everyday use.

The following points should be included in the action plan of the GreenBuilding-Partners, if they are in the field of lighting energy savings:

 

  • Inventory of lighting components and system functioning
  • Assessment of the applicability of possible energy saving measure
  • Action Plan, which defines what the Partner has decided to do to reduce operating costs by improving energy efficiency
  • Report on the results of implementing the Action Plan

The company´s Action Plan for lighting systems should indicate:

  • The measures you have decided to implement
  • The time scale for their implementation
  • The expected energy savings
  • The reasons for excluding the other measures
