Building Electrical Sub-meters

A recent effort has resulted in deployment of electrical sub-meters across campus. Presently just about every building is sub-metered with the data being collected in 15 minute increments and collected every 24 hours. This effort enables a much more detailed characterization of our electrical use.

The following graphs are for use between September 18 and October 2 2012

The above graphs show electricity consumption for "K Hall" (EKH) in red, Student Services Building in dark blue, Life Sciences in green, and the Chiller Plant (AC for UCB) in light blue. Notice how much electricity is used for air conditioning.

 

submeter

The above graphs show electricity consumption between September 18 2012, and October 2, 2012. The data include UCB in red, Student Life Center in blue, and the Campus Center in green. It's interesting that the SLC uses almost as much electricity as the UCB, which contains our Computer Server Center.

 

 

The following graph shows energy used data (collected every 15 minutes) from 7/30/12 to 8/23/12. This graph includes usage data from UCB (blue), main chiller plant/AC (in red), Life Sciences (yellow), the Diesel Mechanics Shop (green), and the baseball stadium (light blue with only three peaks)

The following are graphs that compare some of the energy usage for several of our buildings

The red and blue graphs are the usage for College Hall A&B (red), and C (blue), and the Theater (green)
