Reaching out to the community in regards to As-Built and the Lunos e2 HRV.  The issue is that to reflect normal operating conditions, the Lunos e2 units, having no dampers which can be closed, they are essentially daylighted and have a significant negative effect on the final BDT.

Any thoughts, experiences and insights?

Thanks Angela,

I have seen a number of Lunos e2 units, but on this particular project, there was 4 within a relatively small building.  Decided to retest out of curiosity, and the difference was over 0.5 ACH.

Because of the difference, I thought best to reach out for other's experiences.
