For our project we did a night illumination plan but off-site lights (public street lights) were causing our measurements to be over 20%. any idea how we can reconcile this difference?

Hi I dont understand how to document a compliance with the interior lights. I can take photos?

The Reference Guide is rather vague on how a manual override should be returned to normal saying just “Manual override capability may be provided for occasional after-hours use.

Hi, our site have an area which lighting system is operating 24/7 in order to support the factory which also operates 24/7. So, can us not add this specific area into the table SSc-8

All exterior lighting was retrofitted to CFL's a few years ago and is below 50W. Do we still need to perform Option 3 and take measurements?

I've been reading the EB&OM stress test, and felt confused about the "multi-tenant difficulty" factor in SSc8. What does it mean?

The first floor of the building that we are working on is 10 feet narrower than the upper floors, in order to accomodate a walkway around a courtyard.

I am looking for some clarification with this credit. I have a copy of LEED Canada for Existing Buildings: Operations and Maintenance 2009, Rating System.

We are working on a multitenant office building, with several vacant spaces. All of the occupied spaces have automatic controls for the interior lighting, but the unoccupied spaces don't.

To ensure that the internal lighting was not interfering on nocturnal environment at least 50% of the nighttime hours, the approach that we used was to automate all the building blinds, establishin
