CIE 097:2005 PDF Download

The CIE 097:2005 standard addresses the issue of diminishing light output in lighting installations over time due to dirt buildup and equipment aging. The standard emphasizes the importance of considering this decrease in light output when designing lighting schemes and recommends the use of a maintenance factor to account for it. By incorporating a suitable maintenance schedule, the decay in light output can be limited.

The standard refers to the ISO 8995/CIE S 008-2001 standard, which suggests a minimum maintenance factor for lighting schemes. It highlights the role of a high maintenance factor and an effective maintenance program in promoting energy-efficient lighting design and reducing the power requirements of installed lighting systems.

CIE 097:2005 provides an overview of the factors that influence the depreciation process and outlines the procedure for estimating the maintenance factor for indoor electric lighting systems. It offers guidance on equipment selection, estimation of economic maintenance cycles, and servicing techniques. While the guide includes some examples of data, it recommends obtaining accurate data from manufacturers.

This standard supersedes the previous standard CIE 97-1992 and is written in English, with a summary also available in French and German. It consists of 34 pages, featuring 13 figures and 6 tables.
