I am working on a project locating on a commercial corridor of a capital city. Per the MLO lighting zone, my project should be in Lighting Zone 3 since MLO allows only a case like New York’s Time Square to be Lighting Zone 4. However, ASHRAE 90.1-2010 describes Lighting Zone 4 as ‘High activity commercial districts in major metropolitan areas as designated by the local jurisdiction.’ Our project site is in Highly Dense Commercial area per the local zoning map. Can we use exterior lighting power allowance for ASHRAE 90.1-2010’s Lighting Zone 4?
