This was very helpful! I found the diagrams particularly useful. Visible lighting design for rooms has a similar problem of uniform illumination, but it is mitigated by the fact that there is significant reflection of the light, which I presume does not apply for far UVC. Has there been any work on planning to relocate existing UV systems to the most critical tasks, if an extreme pandemic hit soon, of making more super PPE/āUV systems?
One unpublished study by a Russian academic and a CDC researcher allegedly estimated that the cost of 1 ACH by ventilation is about $135.91 USD and by GUV is about $14.44 USD.[131] 1DaySooner and Rethink Priorities have estimates that āThe price of current systems is currently too high for at-scale deployment, though there are reasons to think the price can be lowered significantly;ā they estimate that the cost of upgrading all U.S. buildings for improved indoor air quality would be about $120 billion - $420 billion.[132]
The units do not appear to be completeācost of 1 ACH for how big of space? Footnote 131 requires a password. Footnote 132 says āall public buildings in the USā not āall US buildings.ā If public building is defined as this, I would guess that would control less than 10% of transmission in the US.
