Hej! Our building is in LZ3 and Lighting Power Allowance for facades is 0.15W/ft2 for each illuminated wall . I understand that these requirements have to be met during working hours, after working hours and during the whole night. That means, it is ok to illuminate the facade with 0.15W/ft2 at night. But we have to meet more requirements for facade lighting (because facade lights are part of the fixtures on site): Document that no more than 5% of the total initial designed fixture lumens (sum total of all fixtures on site) are emitted at an angle of 90 degrees or higher from nadir (straight down). Please advise weather we understood all the requirements for facade lights correctly. Many thanks!
