Lighting audits are necessary for most commercial, industrial, and institutional buildings. It is a simple process that helps know the present lighting situation. It is used to assess current and future lighting demands, current lighting losses, and other related things. This audit is carried out to utilize the lighting systems efficiently, reduce energy use, reduce operating costs, remove the lights not needed, and add more lights where necessary. Any lighting system upgrade of a large building must start with an audit of its lighting setups.
The information obtained from this audit is valuable in improving energy efficiency. Any improvement in this aspect can be made only when the lighting energy usage of the building is known. An energy auditor visits the building and carries out different types of checks. Building administrators may be interviewed to know the lighting problems they face. Areas facing lighting issues are identified. This onsite audit is recommended highly for large buildings where lots of lighting systems are installed.
