Dear all,
Once I saw a LEED Interpretation stating that small spaces, or private offices, could be exempt of installing CO2 sensors to comply with this credit, for CI only, not to NC.
I can't find the LI now. Can someone help me with the number of the LI? And is there a similar interpretation exempting us to install CO2 sensor in private offices for NC?
Regards,
Anderson

I'm not aware of an LI, but you only need sensors in densely occupied spaces of 25 people within 1000 s.f. For a 100 s.f. office to need a sensor it would have to accommodate 3 people. Is that your situation?

Thank you for your reply Michelle.
Yes, our situation is similar to what you described. We have a 25 s.f. space with one person.

I did a little digging and the only thing I found was a post in LEEDUser saying that there is not exception for CO2 monitors is rooms with fewer than 10 people. (Vamshi Gooje Nov 21 2011 in response to a question from Dylan)
Though I'm not sure what the source of this information is.
I think your situation is worth submitting a CIR. It seems a little overkill to provide a CO2 sensor for such a small space serving one person. However also consider how long this person is in this 5'x5' space. Is it really regularly occupied or just used intermittently? If I was stuck in a 25 sf space all day I'd feel better knowing that fresh air was being brought in if the CO2 levels were elevated.
