Yikes! In the first edition's preface, written in 1989, I indicated that the idea for a lighting design textbook came to me nearly ten years prior (so that's now long ago!). Certainly this book idea was not, and still is not, a unique one, but as both a practicing lighting designer and an educator (with stints at Michigan State University, The Pennsylvania State University, Wayne State University, and the University of Michigan since 1980), I thought I could bring a valuable perspective to the writing, reading, teaching, and learning of lighting design. The first edition was fun to write. Feedback on its readability was quite positive. Some universities adopted it as a class text, which was gratifying. But as I used the text myself, I saw shortcomings in its breadth. Further changes in technology since 1995 left much of the lamp, ballast, and luminaire discussions dated.

So, this second edition was encouraged by my editor at John Wiley & Sons, Inc., Margaret Cummins. Many thanks to her for the encouragement and for working through the enormous task of updating and renewing the text. Indeed, what started as an effort to inject some new material, update others, and leave nearly half of the text as it was, grew into a significant makeover. This is a second edition in title only. All new artwork, all new text and tables, and major additions of material constitute this second edition of Architectural Lighting Design.

Since 1990, priorities have changed in lighting design and in design practice. More is expected faster (by everyone of everyone else). Energy efficiency is growing in importance. Sustainability is now a priority. And yet, comfort in living and working environments, and productivity in work settings remain paramount to our present human condition. Lighting is in the thick of it more than people realize. This text addresses lighting as the important, indeed critical, building system and design medium that it is.

Without good lighting, there is little reason to design such things as expensive granite lobby walls, or to detail beautiful millwork, or to break the bank on the best computers, or to spend millions on streetscapes. Without good lighting, we waste billions of dollars on salaries, benefits, and on energy as folks are less comfortable and less productive. Good lighting does not mean expensive except when compared to most of the lousy stuff passed off as "lighting" onto unsuspecting buyers and users every day. This second edition more broadly covers lighting than its predecessor. An introductory chapter sets the stage for lighting as a medium and a business. The second chapter addresses lighting as the solution that it is to the biology of seeing. The remainder of the text essentially follows the phasing of most projects' design efforts--defining scope; programming; schematic design; design development (encompassed by several chapters--daylighting; lamps; luminaires; controls; design tools); contract documents; and construction administration. There was a lot of material left on the cutting room floor. Look for some of this to perhaps show up on the website (www.ald2e.com). This is where updates will be posted and direct links are available to the online references cited herein.

Acknowledgments

There are many folks responsible in some way for my effort here. I specifically wish to thank Professor John Flynn for his devotion to lighting and architectural engineering during his tenure at Penn State. He taught me to appreciate light. Thanks also to Steve Squillace, David DiLaura, and Mark Rea.

Steve was my boss and mentor at Smith, Hinchman & Grylls in Detroit in the late 1970s and early 1980s. Steve was responsible for my career in lighting design. David, now at the University of Colorado, was (and still is) the provocateur--asking the tough questions about the vagaries of lighting design--and at the same time he was the illuminating engineer to whom many of us turned (and still do turn) for technically accurate answers to lighting quantity and performance questions. Mark, now with the Lighting Research Center at Rensselaer, was (and also still is) an even more direct (shall I say pushy?) provocateur. His questions were/ are not only pointed, but less rhetorical and more practical. These folks help push my level of interest and professionalism in lighting, and for that I thank them immensely.

Mrs. John Flynn was instrumental in fulfilling my efforts to present some of Professor Flynn's work here in Chapter 4. Mrs. Flynn has kept much of John's work intact and available for review and, in this case, publication so that others may learn from his endeavors in the subjective aspects of lighting.

Although running the Flynn clan is indeed Mrs. Flynn's priority, she has always been gracious in finding time to talk and meet with me about John's work. She was most gracious to offer the images that are Figures 4.22 through 4.27. Thank you, Iris.

Virginia North, now with Lawrence Technological University, took the time and trouble more than five years ago to review the first edition of Architectural Lighting Design, annotate her copy, and turn it over to me for consideration in development of this second edition. Her review served as a preliminary outline for updating the book. Many of her notes were literally interpreted and used in the writing of this second edition. Thank you, Virginia.

Bob Davis, now with the University of Colorado, was kind enough to critique the first four chapters. These were major rewrite efforts and set the tone for the rest of the book. I very much enjoyed Bob's critical approach that kept me, and the second edition, on track. Thank you, Bob.

Reviewers over the last decade have been most helpful in this rewrite effort. Some of these are indeed anonymous (as is typical in the book business, reviews are sought by potential users [in this case, university instructors] of both the first edition and of the proposed outline for revising the text--anonymity helps assure a sincere review). One reviewer whose effort was published and that helped shape the text in parts was Bob Marans, professor at the University of Michigan. A very insightful critique that I have attempted to address in this second edition. Thank you.

Thanks to my staff, Gary Woodall, LC, IES, IALD, and Damon Grimes for their help in artwork development, review, and keeping the practice going while I was writing. Thanks to my wife, Laura, and daughter, Heather, for what is becoming a biennial effort allowing me to write away in quiet. Thanks to the manufacturers for permission to use their respective artwork throughout. Finally, where would I be without copyeditors? Thanks very much to Diana Cisek and Liz Roles for such a thorough effort.

Practice and enjoy good lighting. Without it we have no environments worthy of the expense, trouble, and environmental havoc they incur.
