The BUG rating system has been created to replace the cutoff system of classifying outdoor luminaires. B (backlight) U (uplight) G (glare) are all scored on a scale of 0-5, with 5 being the highest amount of maximum zonal lumens emitted from the fixture in a direction and 0 being the lowest. Backlight consists of the amount of light in the BL, BM, BH and BVH zones, which is any light that is shining in the opposite direction of the area intended to be lit. Uplight is measured in UL and UH, which cause skyglow and wasted energy respectively. Glare […]
The requirements in the 2015 IECC for lighting control systems have changed and are greatly expanded from what was required in the 2012 version of the IECC. Automatic daylight harvesting, more specific occupancy sensor requirements, and specific controls testing requirements are a few of the changes that will greatly impact controls systems designs. MH has prepared a presentation that provides a summary of all the requirements in this code. This information will be invaluable to every member of the design and construction team for any given project.

“The Lighting Controls Association (LCA), administered by the National Electrical Manufacturers Association (NEMA), is dedicated to educating the professional building design, construction and management communities about the benefits and operation of automatic switching and dimming controls. These benefits include energy savings, flexibility and higher-quality building environments.” This link will take you to the LCA’s home page.
