Audits for lighting are an investigative process that measures actual lighting conditions against standards for lighting.
To conduct lighting audits, it is necessary to go through the entire area being audited and observing the quantity and quality of the installed lighting. A note is made of areas with inadequate lighting, high level of lighting, areas that are lit up unnecessarily, and where the lighting levels cause any discomfort to those who work there. It is necessary to take a detailed measurement of illumination with light meters.
Areas that can benefit from task lighting instead of the general lighting available are identified. This can be often accomplished by lowering lighting or providing specific lighting for the task. The cleanliness of bulbs and fittings can improve lighting and is best undertaken before the audit so that the results obtained are from actual working conditions.
