Since the repair work, the temperature is significantly cooler. Surprisingly, even at the vertex (to be more specific, inside the PSL enclosure, which for the time being is the only place where we have a logged temperature sensor, but this is not attributable to any change in the HEPA speed), the temperature is a good 3 deg C cooler than it was before the HVAC work (even though Koji's wind vane suggest the vents at the vertex were working). The setpoint for the entire lab was modified? What should the setpoint even be?

- I went to the south arm. There are two big vent ducts for the outlets and intakes. Both are not flowing the air.
The current temp at 7pm was ~30degC. Max and min were 31degC and 18degC.
- Then I went to the vertex and the east arm. The outlets and intakes are flowing.
