A lighting audit is an investigative process that measures conditions against standards to determine where cost-effective changes can be made
The first step is a walk-through of the plant to observe the quantity and quality of available light. Problems are noted such as an area where lighting levels are too high, where lights are left on unnecessarily, or where factors leading to visual discomfort may inhibit productivity or safety.
The type, quantity, location and height of lamps and fixtures are recorded.
Detailed measurements of illumination levels are taken with a lightmeter, both at task areas and for general overall lighting
Next, simple retrofit possibilities, such as switching from general lighting to task lighting are considered.
After all the simple retrofit options are examined, a plan for the general modification of the plant lighting is devised. Such a plan integrates simple modifications and major improvements into a cohesive, energy efficient system.
