IES RP-28-16

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.

IES DG-26-16

Design Guide for Lighting the Roadway in Work Zones

Published by: 2016-12-20 / 2016-12-20 / 13 pages
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.

ANSI/IES RP-22-11

Tunnel Lighting

Published by IES (Illuminating Engineering Society) in February 2011, 60 pages
ISBN: 9780879952518
This Standard Practice has the objective of providing information to assist engineers and designers in determining lighting needs, recommending solutions, and evaluating resulting visibility at vehicular tunnel approaches and interiors. This Practice is intended also for use by administrators charged with the responsibility of providing a safe visual environment within a tunnel both day and night.

The IES Lighting Handbook, Tenth Edition

Editors: David DiLaura, Kevin Houser, Richard Mistrick, Gary Steffy
The 10th edition of Illuminating Engineering Society Handbook has 1087 pages (ISBN 9780879952419).

Successful lighting professionals must be able to incorporate into their work many new technological and scientific developments. Examples: solid state lighting sources; humans’ perception of light as they age, sustainability and the integration of daylighting with electric lighting; the effects of light on human health; to name a few. Clients rely on and, indeed, expect lighting practitioners to know their specialties and to make well-informed decisions and recommendations on the client’s behalf. That is why the 10th edition of the new IES Lighting Handbook is an essential knowledge reference for anyone in lighting. The 10th edition brings together some of the best minds in the lighting community to present the current state of knowledge as it relates to lighting and lighting design. With reliable and comprehensive information in a single source, practitioners can approach projects with confidence.

Changes to the new edition:

  • Provides a compendium of what is known that directly relates to lighting and lighting design
  • Concise explanation of material
  • Content and format tailored to those involved in lighting decisions including practitioners, designers, architects, and engineers
  • Four color throughout; 600+ illustrations that enhance understanding
  • Conveniently-referenced tabular information is exemplified with numerous photographs and illustrations
  • Sustainable practice embedded throughout: refinement of light level criteria, definitive criteria related to brightness and user impressions, factors influencing power and energy use for lighting, and methods to minimize light trespass and light pollution

Features:

  • New illuminance determination procedure consisting of visual age-based illuminance ranges and mesopic adaptation
  • Extensive updates on light sources, including solid state lighting
  • Holistic and complementary daylighting and electric lighting strategies
  • More extensive and specific qualitative lighting design criteria such as subjective impressions (psychological factors) and architectural spatial factors
  • Broader quantitative criteria such as illuminance uniformities, power and energy aspects, light trespass, and light pollution
  • In-depth coverage of sustainability practices: new chapters on daylighting, controls, sustainability, commissioning and energy management
