The transition to LED’s has dramatically changed our workspace. This is not news. The original value proposition of more light, for less power has been fulfilled, but not uniformly, and not always with design utility as the driving force. With the number of manufacturers promising a “spec grade downlight at <$200 DN” increasing on a daily basis, it’s becoming harder and harder to marry luminaires from different lines into a coherent specification package. One means of correcting for the eccentricities of differing priorities is through a well thought out, thorough control specification. This can be a daunting task as virtually all manufacturers are capable of providing multiple approaches to control—sometimes with differing results. In the past, it was enough to know which fixtures needed to dim, but current code requirements and a variety of technologies which may or may not work together makes a clear specification essential. This presentation will provide guidance about common areas of difficulty, and will discuss the use of the control narrative as a specification tool and as a means of communicating design intent in a clear and coherent manner.
