Dear all,
Does anyone know if there is an ACP rule for sampling points for the air quality tests. I didn't find an ACP in LEED 2009 BD+C Supplemental Reference Guide with Alternative Compliance Paths for Europe.

The project I work on is composed of 5 identical buildings over 645,000 square feet. I wanted to know if I could consider one building as a baseline building instead of doing tests in 5 buildings.
Thank you for your help.
