I tried to fiend a definition of "Shield envelope openings that have a direct line of sight to non-emergency luminaires".

We are developing a principal design for an industrial building within zone LZ2 or 3, depending on where it is located in the world.

We are working on a maintenance facility for a landfill (Don't worry - there is a big compost and container recycling operation there too!) They will be operating and maintaining garbage trucks.

Please address this in a paragraph or two.

My project is a Data Center located within a very urbanized area and surrounded by other buildings (located very close) thus any kind of lighting is not needed.

The site boundary of our building is lined with quite tall and dense trees. Should these be incorporated into the footcandle calculations?

We have a permanent free standing canopy over all of the parking spaces on site. Would this fall under the canopy allowance for lighting power density calculations?

1. One of our project have around 1000 m2 landscaping area. In which they are using 20 numbers of 10W bollard external lighting in only 400m2 area.

I have a state owned youth detention center (jail) project in lighting zone LZ1.

Tristan asked me to review the November 2011 addenda for this Credit.
