Most office HVAC systems have outlets and
return
vents in the ceiling.
By moving the return vents to the floor, or on walls
near
the floor, we could help to reduce airborne
pathogens by
providing a vertical current that aligns with gravity.
Keeping the return vents clean could be trickier...

Perhaps the return air could be bubbled through a water
bath that seeped into the sewer. |

Perhaps Holy Water could be sprayed into the outlet airstream to humidify, bless the recipients*, and instantly kill any airborne pathogens ? |

*R.C. and Orthodox. Other denominations are available. As your philosophy adviser if religion is right for you. |

Hmm, my HVAC outlets are in the floor and the returns high
up on the walls. Backward. I think that's to push cold air in
at the bottom and suck out the hotter air from above. That
would mean that a top-down cooling system would be
fighting convection. Is that ideal? |

Depends on if you're heating or cooling I guess. |

Over a distance of 2.5 m and a temperature differential of (say) 10 C, the difference in density isn't going to be enough to put up much opposition to even a modestly sized fan. |

The maths of thermo-syphoning are fairly simple, and besides there will be so much turbulence and mixing that the temperature away from the inlet grille will be relatively uniform. |

Where this gets a little tricky is in the filtering; with dirty
floors becoming now an HVAC issue; the benefits may be
buried by the increased dirt intake. |

Adding a UV light in the loop would be a benefit. I'm
contemplating doing something like that to my home
system. |
