Supply fan air flows and chilled water pump frequency
As requested by Robert Schofield, I have dialed back the supply fan air flows in the LVEA to ~ 10,000 CFM per fan and the End Stations to ~ 9000 CFM per fan.  

Currently there are 3 fans running in the LVEA, SF 2,3,&4. AHU-3 has both SF-1 and 2 running at ~9000 CFM. Each end station has only 1 fan running at the time.

In addition to dialing the fan flows down, Robert also requested that the frequency of all the chilled water pumps on site be dialed back to 45 Hz. I was able to travel to both end stations since we were not in observation mode earlier this morning and those pumps have been set at 45 Hz. The corner station chilled water pump was previously set at 45 Hz.

We will attempt to maintain these parameters as long as the VEA temperatures remain stable.
