February 10th—Model Lighting Ordinance (MLO)


Join us Tuesday, February 10, as Dawn De Grazio, MIES, LC of Lighting Analysts presents the Model Lighting Ordinance (MLO). 


After years in development as a joint effort by the Illuminating Engineering Society and the International Dark-Sky Association, the MLO was released in June 2011.  The purpose of the MLO is to provide a well-written, adoptable ordinance to help communities achieve quality

nighttime lighting while minimizing obtrusive light and negative impacts on the environment.  This webinar will cover the various parts of the MLO, including Residential and Non-Residential lighting requirements, the Prescriptive Method and Performance Method, and some relatively

new terms that the MLO makes use of, such as Lighting Zones and BUG Ratings.
