Hello all,

It's first time that I work with LEED regulations and can't find something about permament installation of PM measuring devices and whether installed devices can improve the rating? There are explanation and regulations for CO2 and TVOC etc. but nothing about particular matter measurements. Compared to WELL rating system, you can get more points by using decentralized PM devices or at least a device with three characteristic of a defined list to get the information of the facility.

Again, can't find similar or same statesments or regulations in the LEED regulations. Can someone confirm my experience?

Thank you all in advance.
