Lighting research center

The Lighting Research Center (LRC)  at Rensselaer Polytechnic Institute is the world’s leading center for lighting research  and education. Established in 1988 by the New York State Energy  research and Development Authority (NYSERDA), the LRC has been pioneering research in energy and the environment, light and health, transportation lighting and safety, and solid-state  lighting for more than 25 years. In 1990, the LRC became the first university research center to offer graduate degrees in lighting and today the LRC offers both a M.S. in lighting as well as
a Ph.D. to educate future leaders in lighting. Internationally recognized as the preeminent source for objective information on all aspects of lighting technology and application, LRC  researchers conduct independent, third-party testing of lighting products in the LRC’s state of the art photometric laboratories, the only university lighting laboratories accredited by the National Voluntary Laboratory Accreditation Program (NVLAP Lab Code: 200480-0). LRC researchers are continuously working to develop new and better ways to measure the value of light and lighting systems, such as the effect of light on human health, and the effect of light on plant physiology. The LRC believes that by accurately matching the lighting technology and application to the needs of the end user, it is possible to design lighting that benefits both society and the environment.

Climate-Based Daylight Modelling

Climate-Based Daylight Modelling is the personal website of John Mardaljevic, Professor of Building Daylight Modelling at the School of Civil & Building Engineering, Loughborough University. He is the pioneer of the development and application of what has become known as climate-based daylight modelling. These techniques have been successfully applied to help solve a wide range of traditional and novel building design problems.


The daylight project

This site celebrates all things daylight; its benefits and influences that inspire and restore human life and the natural surroundings in which we exist. It is constructed, owned and maintained by VELUX Company LTD.


Daylighting collaborative

The Daylighting Collaborative was initiated by the Energy Center of Wisconsin and its sponsoring members as a source of why-do and how-to information for daylighting using windows. With the growing interest in the energy savings benefits and research on the other non-energy related benefits, the Daylighting Collaborative and its website were re-focused to not only provide information but act as a gateway to other existing information on daylighting.

An invited Advisory Committee acts as a sounding board and general technical oversight and insight for the staff.

The Daylighting Collaborative is funded through grants and sponsorships received from utilities, government, foundations and product manufacturers and other sponsors.


Dansk Center for Lys

The Danish Lighting Center was founded in 1948. The object of the center is to promote the use of good and appropriate lighting.  And to advance knowledge and to disseminate information for the improvement of the lighted environment to the benefit of society.

IES - Illuminating Engineering Society

The Illuminating Engineering Society of North America (IES) is the recognized technical authority on illumination. For over 100 years; its objective has been to communicate information on all aspects of good lighting practice to its members, to the lighting community, and to consumers, through a variety of programs, publications, and services.

IES is a forum for the exchange of ideas and information, and a vehicle for its members’ professional development and recognition. Through technical committees, with hundreds of qualified individuals from the lighting and user communities, IES correlates research, investigations, and discussions to guide lighting professionals and lay persons via consensus-based lighting recommendations.

The Society publishes nearly 100 varied technical publications, and works cooperatively with related organizations on a variety of programs and in the production of jointly published documents and standards.

Local IES Sections and many lighting corporations offer formal educational programs on lighting, utilizing material developed by IES. Sections offer programs related to specific applications based on IES standards – seminars on sports and recreational lighting, lighting industrial facilities, roadway lighting, museum lighting, to name a few. Virtually every curriculum devoted to lighting – from beginner to advanced – includes IES educational materials.

IES is almost 8,000 members strong. Its members work with lighting in a variety of capacities – lighting designers, architects, interior designers, government & utility personnel, engineers, contractors, manufacturers, distributors, researchers and educators – throughout the United States, Canada, Mexico – and around the world. They share a common interest in lighting, and a common desire to promote the use of the latest, most innovative lighting technologies, with a focus on judicious use of energy in all lighting applications.


CIE - The International Commission on Illumination

The International Commission on Illumination – also known as the CIE from its French title, the Commission Internationale de l´Eclairage – is devoted to worldwide cooperation and the exchange of information on all matters relating to the science and art of light and lighting, colour and vision, photobiology and image technology.
