Help With SS Credit 1 Option 2 Path 6

Your fine. Your co-worker is being too literal in his reading of this. Think of manual override first. Turn the lights on and they have to have a timer or something to turn off after 30 minutes. If you need more light after that you push the button again and you get another 30 minutes. Now the occupancy sensor is like pushing the button for another 30 minutes everytime it sees your movement. Also the Life Safety Code requires enough light (min 1 fc) for people to get out of the building any time it's occupied. Having lights shut off after 30 minutes regardless of people still being in the building would violate the law if it leaves the space in darkness.

I have been getting some really dumb responses from LEED reviewers lately. It would not surprise me if one tried to enforce it as your co-worker views it. The equipment and programming required to make this work is extensive. And then there's the whole Code violation thing.

I agree with Bill's comments. FYI - check with your Client to determine if the 30 minute override will be acceptable. (Some find this incredibly annoying.) For some business that often have after-hours employees, you may want to consider using motorized blackout shades on a timer for the offending light fixtures. FYI, I'm a lighting designer and have met the credit this way on previous projects.

Can I ask for a clarification to Option 2 Path 6? Is this a requirement for the tenant space only or the total building. I am not sure because this is in the Sustainable Site area. Thanks.

It's the building, not just the project space, which you have to apply this to.

Susann, thanks for your response. I thought that would be the case since this is a SS credit. Unfortunately, this path is harder to achieve when the project is in a large and older building with multiple tenants.

Hi, Are the "non-business hours" of option 1 the same as the ones of option 2 (11pm to 5am)? My project is in a large building with multiple tenants too, but I think is possible that the building is closed (and lights are off) at that times.
