What needs to be in the building during the air samples? I am confused about "moveable" furniture with "workstations and partitions" as examples when these are not really "moveable".

Hello,

I am looking for a company that will do the Option 2 testing for a large commercial building in British Columbia, Canada.  Does anyone know of any companies?

Thanks.

I have been advised that the TSI Dust-Trak DRX can now be used for the particulate measurements.

Has anyone used this successfully (gained certification)?

Hello all,

Indoor Air Quality Assesment: Were are using path 2 During occupancy and we had 1 day were the outdoor humidity exceeded 60% RH.

Does anyone have any good suggestions of measurement equipment that meet the LEED v4.1 requirements for particulate matter?

I'm hearing from a potential EHS contractor that the testing labs are having a hard time ramping up to meet the testing requirements of v4.1, and the testing is going to be quite expensive.  I

The v4.1 standard VOC & particulate testing requires, that the testing is made "after the construction has ended and before occupancy".

In order to meet the Path 1 requirement for the Indoor Air Quality Assessment, does Ozone sampling need to be performed regardless if the facility is in an EPA Non-attainment zone or not?

Does anyone have any hand held meters for measuring TVOC they would recommend?
