17-0314 v2.1/IAQ Testing Threshold Guidance and Pre-Occupancy Results (Part Two)

Greetings,

Burh Becc is a single-family residence and working farm. This request is a follow-up to our IAQ threshold inquiry previously posted.

Our PM-10 pre-occupancy testing results are as follows: 

Garage Meeting Room: 928 micrograms/m3; this was expectedly high due to various issues, which are noted in our IAQ report to be submitted during the Preliminary Audit. I expect that this value will decrease significantly; however, given it's a space off the garage used for farm operations the 30 micrograms/m3 requirement may be difficult to reach. 

Kitchen (Main House): 76 micrograms/m3; This was surprisingly high due to the extent the team went to in regards to housekeeping during construction and prior to the test. As indicated in the previous Dialogue post, the Owners have several indoor pets as well as a wood fireplace (allowed given our Transect). Our concern is that the 30 micrograms/m3 requirement may be difficult to reach due to these caveats no matter how well they maintain their home. 

While we have not reached the post-occupancy testing date yet, this inquiry is being submitted to be proactive. Our proposal, in lieu of repeatedly testing and failing PM-10 tests, is to continuously monitor the IAQ to provide the owners with the information on a regular basis just like energy and water metering. This would allow them to have ongoing knowledge of the home's indoor air quality rather than based on the specific day that the re-testing is completed. Given the lab fees for these tests are quite expensive, we want to ensure we are doing our best to be diligent in meeting the Imperative requirements while respecting project funds should additional testing to meet the 30 micrograms/m3 requirement be needed beyond the post-occupancy retest. 

Regards,

Burh Becc at Beacon Springs Team
