Hi, can anyone please comment/confirm that Dialux software can be used to work out the credit requirements with regards to exterior ligting?

How does this credit take into consideration lighting for comfort?

The contractor on a LEED site would like to put a billboard up.

I'm note sure to understand the fourth demand of this credit.

I have a adjustable fixture mounted on the ground to uplight the tree. The initial fixture lumen above 90 degrees from nadir is 0 which is full cut off fixture.

city owned lights are not included in our photometric calculations, but how in reality can somebody check that the lights are matching our calculations if the city-owned lights are there anyways?

In version 2009, I have to shutoff or reduce interior lighting. The interior space is a chiller plant where lighting shutoff or reduction would create a safety risk.

Can I use the ASHRAE table and methodology of demonstrating LPD compliance?

I was still hoping for an answer to the following regarding Automatic Shading Devices: This credit asks for uploads of product specifications, location plan, and riser diagram for automatic shadin

I have a dumb question - when they ask for Initial fixture lumens per lumenaire, do they want fixture output lumens or the lamp lumens? Big difference in the percentage calc.
