Hello, Do we need a laboratory test report to substantiate the SRI, or the Data Sheet by manufacturer is sufficient ?

Hi all,

I work for a waste hauler and am trying to figure out if there is any certification that we need in order to help LEED builders.

One of our data center projects has an electrical room. This electrical room didn't have regular occupants.  In this case, do we need to provide fresh air for that space?

In the context of a refurbishment, are the existing luminaires exempt from complying with the exterior lighting power and/or exterior lighting control requirements stated in ASHRAE 90.1:2010 sectio

LEED v.3 specifically stated that school buses counted toward this credit. They've taken that language out for v.4. And interestingly, the bus route only counts in one direction.

My jewelry store (100m2) has general lighting on the ceiling and millwork lighting for decorative purposes. The general lighting is 16W/m2 compared to the baseline of 18 W/m2.
