The total chilled water volume and removed heat refers to the time since installation of the corresponding meters. AHU1...6 refers to the heat from the air handling units in levels 1...6, PCW2 to the process water for labs 2/15, 2/16, 1/16, 1/16. Meter installation date were:

1 April 2011, 7pm for AHU1 / AHU2,
11 July 2011, 5pm or so for AHU3 / AHU4,
17 August 2011 for PCW2,
9 February 2012 for AHU level 6,
16 August 2017 for AHU S14 level 3.
(?)August 2022 for AHU S15 level 5.

CQT Electricity metering status

Displayed values reflect the meter readings at the indicated date/time. Instant values give an idea about the consumption at this moment, the total values represent the accumulated consumption since the meter installation. New readings are available every 2 minutes.
