CHAPTER 1
INTRODUCTION
1-1
PURPOSE AND SCOPE. This UFC provides guidance for the design of
interior and exterior lighting systems for the Unified Facilities Criteria based on the
Illuminating Engineering Society of North America's (IESNA) Lighting Handbook
Reference and Application, 9th Edition (hereafter called Lighting Handbook) and current
recommended practices. This UFC meets the current IESNA standard of practice and
addresses general lighting requirements for Department of Defense (DoD) facilities.
Specific requirements not outlined here may apply to facilities overseas.
Lighting Handbook. In 2000, the IESNA published the 9th Edition of the
1-1.1
handbook, which changed the direction of lighting design criteria. In previous editions,
illuminance values were given as the strongest basis for design. In the 9th edition of the
Lighting Handbook, the single focus on the illuminance criteria is no longer possible.
Now the emphasis is on quality based design. Chapter 10 of the handbook, "Quality of
the Visual Environment" formalizes these issues in a Lighting Design matrix and rates
the importance of each for different applications.
1-1.2
Lighting Design Criteria. Lighting practitioners must evaluate the
application and consider the important lighting design criteria, including direct glare,
surface luminances, and uniformity. Also, the importance of daylight on human health
and productivity is emphasized.
1-1.3
Exterior Lighting. Exterior lighting design now addresses the role of glare in
creating poor visibility. Over-lighting and discontinuity between areas is also addressed
as this could cause adaptation delays when moving from one area to another. Also, the
increased effectiveness of white light on enhanced peripheral detection for exterior and
other low lighting level applications is addressed.
1-2
APPLICABILITY. These guidelines apply to all service elements and
contractors designing interior or exterior lighting systems for new and retrofit
construction projects.
