Phillip  and Tim from Caltech physical plant talked with us today down in the lab about what to do about the HVAC.

They're going to swap out the pre-filters in the air handling room, install another flow meter to check the lab air pressure, and install another temperature sensor in the lab (underneath the south cabinets).

We should record in the ELOG some of the temperature transients we're having now that we think are associated with opening the lab doors. Then we can do a quantitative before and after test to see how things change afterwards.

We probably should also put a temperature sensor out in the hallway to see what's going on out there.
