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

On first submittal of this credit, we got the comment that our project was actually in an LZ-2 zone instead of an LZ-3 zone.

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?

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

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