Can I consider entrance lighting (light fixtures above the building entrance) a safety and comfort lighting? And therefore not to include it in the calculations?

Hello, We are working to certify a building with heliport on the rooftop.

We are calculating the Exterior Lighting Power Density on a project that has building facade lighting on each facade.

1. Is any advertising lighting installed on a facade included in illuminance simulations? 2. It is written here (Bird's eye view) that advertising is not included in LPD calculations.

No Nontradable Surfaces are illuminated; nothing to enter into Table SSc8-2. When we Check Compliance, this table is highlighted.

Please advise the definition of vertical footcandles. When measuring the vertical footcandles of the site boundary, at what distance level shall the calculation point be?

After Reading the comments, that an internally illuminated advertising signs are exempt, Can I say that if I have an internally illuminated advertising sign on a facade, it doesn't affect the credi

Hi, How can in prove SSc8 for interior lighting, when my warehouse don't have windows? The building is just a warehouse.

We are trying to determine the exterior lighting power densities for a Core and Shell project and have a doubt regarding a surface type per ASHRAE 90.1.
