Illuminating Engineering Society. The Illuminating Engineering Society (IES), is an industry-backed, not-for-profit, learned society that was founded in New York City on January 10, 1906. The IES's stated mission is "to improve the lighted environment by bringing together those with lighting knowledge and by translating that knowledge into actions that benefit the public".

Since 1906, when the IES was legally incorporated, the IES has always been known as the "IES". However, in 1981 the 6th edition IES Lighting Handbook published the phrase, "Illuminating Engineering Society of North America("IESNA"). The "IESNA" moniker persisted until it was removed in 2010 when the 10th Edition of Lighting Handbook was released. The IES is a global organization with sections worldwide and solely related to North America.

The Society is headquartered in New York City. The IES is divided into approximately 100 local sections.

Notably, the London-based Society of Light and Lighting (a part of the Chartered Institution of Building Services Engineers), was originally founded in 1909 as the Illuminating Engineering Society.

Publications

The IES is credited with over 100 publications on the subject of lighting such as The Lighting Handbook: 10th Edition. Other publications, many of which are American National Standards Institute (ANSI) or ASHRAE standards, include recommended practices for a variety of specific lighting applications such as office, sports, and outdoor lighting, and lighting for healthcare facilities. The National Institute of Standards and Technology (NIST) references several IES publications for Optical Radiation Calibrations. The International Dark-Sky Association (IDA) makes several references to the IES and its publications in its Outdoor Lighting Code Handbook.

IES published Transactions of the Illuminating Engineering Society from 1906 to 1939, and replaced it with the monthly Illuminating Engineering in 1940. The latter was succeeded by two IES publications in 1971: Lighting Design & Application (LD&A) magazine and the Journal of the Illuminating Engineering Society. The magazine was renamed LD+A in 1982, and the journal was renamed LEUKOS in 2004. 

Notably, the London-based namesake described above published its own Transactions of the Illuminating Engineering Society until 1968.

LEUKOS is published by Taylor & Francis with four issues per year.

LD+A is published by Sage Journals and is free to members.

Illumination Awards

Annually since 1973, the IES Illumination Awards program has recognized individual engineers and lighting designers for meritorious original design in a nominated project. While local sections may offer their own awards, there are five international award categories:
