Bibliography

Describes the approved method of verifying the monthly and annual energy use for lighting in non-residential buildings. The method described includes the division of a building into zones as required for lighting technology purposes, determination of the specific electric power requirements ('electrical evaluation power') of the artificial lighting system, as well as considerations on the way in which daylight is utilized and the effects of presence detection systems.
