What are the standards for streetlighting in Calgary?
All roadway lighting system designs in Calgary are based on IESNA (Illuminating Engineering Society of North America) guidelines for roadway lighting. These guidelines establish appropriate lighting levels, visibility levels and uniformity of lighting levels for a given class and operational characteristics of a roadway (e.g., traffic volume, speed and potential for pedestrian conflicts). For more detailed information, refer to the IESNA website at www.iesna.org . Additionally, The City has a policy to minimize light pollution and energy consumption through the use of lower wattage flat lens fixtures which focus lighting on the street level, and to recycle all lighting materials.
