SINCE 2000, AN AVERAGE OF 60% of Americans have iden- tified themselves as a sports fan, according to Gallup. In 2016, U.S. construction spending on amusement and recreation facilities (not including those built as part of educational facilities) increased nearly 10% to about $22 billion. In regard to lighting, new and renovated facili- ties are a juncture of venerable best practice, robust regulation, and new technology. In 2015, the Illuminating Engin- eering Society (IES) published an update to RP- 6, Sports and Recrea- tional Area Lighting. RP- 6 states, “The goal of lighting for sports is to provide an appropriate luminous environment that contributes to the visibility of the playing target (ball), the competitors, and the surround- ing backgrounds.” Put another way, sports lighting should deliver optimal light levels and visual comfort for play and spectating. Achieving this goal requires ad- dressing quantity of illumination

or providing minimum maintained horizontal and/or vertical light levels. It also requires addressing quality of illumination, which incor- porates a range of factors such as uniformity, glare, modeling, and color quality. Care should be taken to mini- mize light trespass and skyglow in outdoor installations as dark-sky communities continue to grow across the United States. Finally, selecting efficient luminaires, avoiding over- lighting, and using lighting controls can achieve good lighting while mini- mizing energy consumption.
Recommendation Considerations Recommendations are geared by sport, venue, and classification of play: • Sports include aerial (e.g., base- ball, basketball, football) and ground level (e.g., hockey, boxing, skating).
