Recommended Practice for Museum and Art Gallery Lighting

Published by: 2017-01-09 / 2017-01-09 / 154 pages

Museum and art gallery lighting design differs from any other type of lighting design because museum objects are unique and many are extremely sensitive to harm from light. The key to damage prevention is environmental control: elimination of atmospheric pollution, stabilization of temperature and humidity, and minimization of exposure to radiant energy. This Recommended Practice, intended primarily for the lighting designer, provides specific standards for satisfying the special requirements of museums and art galleries. Other decision makers, such as the museum administrator, the curator, the conservator, and the exhibit designer, can use this Practice to improve understanding and communication throughout the exhibition process.

This Practice covers museum and art gallery lighting from a dozen perspectives: successful museum lighting introducing the concept of team decision making; design guidelines melding artistic basics with
key technical considerations; damage to museum exhibits revealing why light causes deterioration and what can be done to minimize the effect; four typical lighting problems categorizing most display situations and the best methods to handle them; architectural aspects and daylight explaining how daylight “presence” can best be used; electric light sources describing the best and worst features of incandescent, fluorescent, and HID lights; luminaires and accessories concentrating on track lighting but also discussing recessed fixtures, pendant fixtures, and fiber optics; light controls explaining when to use manual switches or programmed systems; control of glare examining direct glare, reflected glare, and excess contrast; measurements and measuring instruments describing current techniques and equipment choices; lighting calculations presenting the accepted methodology with worked examples; and maintenance and budgets giving a comprehensive maintenance checklist and a sample database that costs out the lighting for a single large gallery. An extensive glossary defines both lighting and architectural terminology.

Because museum and art gallery lighting design is attributed here to a collaboration between art and science, success depends upon team decisions. Decisions that must satisfy a diverse range of interests, expertise, and professional pride. Therefore, a systems approach to lighting design is advocated throughout this Practice. For example, artifact placement (relative to conservation needs) can greatly affect overall illumination levels, the curator’s intended message, and the physical layout of the museum/gallery. Therefore, the impact of lighting on museum occupants, artifacts, and the environment must be jointly considered. [Note: RP-30-96 is a “trial use” American National Standard.]

Design Guide for Color and Illumination

Published by: 2016-01-01 / 2016-01-01 / 78 pages
IES DG-1-16 describes the proper use of color and illumination in the design of visually functional environments. For most people, the experience of color is only vaguely understood in traditionally accepted terms, and the absence of clear language causes problems. A Universal Color Language was therefore created based on the Munsell Color System. As this Guide explains, the System organizes color into a three-dimensional color arrangement consisting of hue, chroma, and value. Color descriptions in the Universal Color Language can be used to set a standard for a transaction or contract, at an appropriate level of accuracy. This Guide covers the basic principles of color measurement, which involve matching an unknown light with a mixture of three given lights using a visual colorimeter.

This Guide also discusses color management, which is helpful to lighting designers who must coordinate their designs with architectural concepts and other plans that are heavily involved with color. It further explains that the esthetics of color can create controversy, and suggests that experience with the effect that color has on people will help designers apply acceptable color schemes and achieve favorable reactions.

Lighting and the Visual Environment for Seniors and the Low Vision Population

Published by: 2016-12-20 / 2016-12-20 / 128 pages
RP-28-16 is intended to increase the designers’ understanding of age-related vision loss and the importance
of their design decisions that could impact the safety and independence of this growing sector of the population. In the 2007 edition, applications were primarily directed at housing and senior care facilities but in the 2016 edition, coverage has been expanded to new areas of interest including offices, hospitality, healthcare, commercial and places of assembly. RP-28-16 has also been revised to serve a wider range of users, including individuals, design professionals, owners/managers of commercial buildings, code and regulatory agencies and legislative bodies. It is well understood that healthcare costs will increase as our elderly population ages. As the United States braces for this huge economic impact, appropriate lighting and a supportive visual environment should be considered as a preventive measure to reduce the risk of falls, sleep disorders and long-term care, and therefore given a top priority by all code officials, governmental agencies and the tax-paying public.

IES LM-37-16

Guide for Determination of Average Luminance (Calculated) for Indoor Luminaires

Published by: 2016-12-20 / 2016-12-20 / 21 pages
The methods of calculating average luminance contained in this Guide cover various open bottom apertures as well as flat and drop lensed units, including units with multiple openings in the light emitting area. The candela values of interest are obtained by means of IES techniques for relative or absolute photometry, and are not obtained from field measurements in application. Note: Average luminaire luminance is not a reliable indicator of either direct or reflected glare due to potential luminance non-uniformity.

The averaging of data from spot luminance measurements obtained with luminance meters or high resolution imaging systems is not within the scope of this document. This calculation is based solely on the candela values obtained by goniometric measurement of the luminaire and the luminous projected area.

All light sources, for which there are current standards for luminaire photometry, are covered by this Guide. These include incandescent, fluorescent, high intensity discharge (HID), low pressure sodium, and LED sources.

This Design Guide provides guidance on evaluating requirements for lighting the roadway to provide visibility for road users transiting through or adjacent to the work area. Criteria for determining the lighting requirements for the conduct of work within a work area are provided in National Cooperative Highway Research Program (NCHRP) Report 498, Illumination Guidelines for Nighttime Highway Work,1 and are not included in IES DG-26-16; except that the impact of glare produced by lighting within the area on driver requirements is considered.

The stipulations and guidance provided in this document should be incorporated into any statement of work for nighttime road work. Furthermore, contractors should be required to adjust the work area lighting if problems are identified after installation, or when directed to do so by the infrastructure owner.

Recommended Practice of Daylighting Buildings

Published by: Illuminating Engineering Society / 2013 / 85 pages
Daylighting refers to the art and practice of admitting beam sunlight, diffuse sky light, and reflected light from exterior surfaces into a building to contribute to lighting requirements and energy savings through the use of electric lighting controls. The role of electric lighting in daylighted spaces should be to complement daylight during daytime and supply the required illumination levels during nighttime.

IES Guidelines for Upgrading Lighting Systems in Commercial and Institutional Spaces

Published by: Illuminating Engineering Society / 06/12/2013 / 87 pages
This document is intended for commercial and institutional building owners, lighting practitioners, managers, facility engineers, energy service companies, retrofitters, and utility representatives considering a lighting upgrade.

Increasing lighting efficiency is often the most cost effective energy efficiency improvement that can be made to an existing building. There are two basic approaches for improving the energy efficiency of an existing lighting system: retrofit or redesign. Retrofitting the existing luminaries will be the more common approach. However, on projects where the existing illumination or lighting equipment no longer suits the space or application, redesign is the better choice. A thorough assessment is necessary to determine if one (or both) of these methods is advantageous over the other.
