This popular, easy-to-read lighting design guide offers a highly visual introduction to the fundamentals of illuminating the single-family home.  Emphasizing the use of "lighting layering" - using a variety of lighting sources together, the book offers advice on design tools and room-by-room lighting strategies.  This Second Edition includes a new chapter on lighting energy efficiency, increased coverage of light sources such as LED lamps, light shelves, "smart glass", and daylighting.  Thirty-two pages of color plates demonstrate professional redesigns of interior and exterior rooms and offices.
