Welcome to my blog series, #3 of 5, on Effective Energy Management from Home. If you haven’t read Blogs #1 & #2, I recommend you give them a quick read first.
You’re an Energy Manager working from home. Your buildings are mainly unoccupied and in shutdown mode, right? A bright side to the crisis is that you’re saving a lot of energy and water.
Or are you? How do you know? Wait a month or two for the utility bills? By then, it’ll be too late. You think and hope your buildings are properly set back or shut down, but without normal occupants or maintenance, custodial, and operations workers there, to say nothing of your occasional walk-throughs, it’s impossible to know for sure.
You have no ears and eyes in the building. And that’s where smart meters and interval data play a vital role in conservation and effective building operations. Below are EnergyCAP interval data dashboard charts for two high school main electric meters. The orange line is the prior week when school was in session. The blue line is the first Governor-ordered shutdown week. Shaded areas are night times and weekends. White areas are weekdays, 6AM–6PM. As the Energy Manager, do you see anything you wish you had checked?
Here’s one, at High School #1, the March 16 and March 20 daytime shutdowns were terrific, right in line with the weekend shutdown load of a steady 100 kW. But what happened on March 17–19? Someone or something turned on an extra 150 kW for most of the day. High School #2 experienced about the same. Even though you’re sitting at home, you could have pulled up the EnergyCAP Dashboard, seen the interval charts in near real time, and immediately investigated (via security cameras, EMS, phone calls) and possibly killed a few hundred unnecessary kWs in just these two schools. And you’re responsible for 50 other buildings, as well. At an average cost of 12 cents/kWh, that’s a daytime savings of about $1.50 per kW of reduction per day. Multiply that by thousands of excess kW and perhaps dozens of days of planned shutdowns, and the savings quickly climbs into the thousands of dollars.
Instead of sitting at home feeling frustrated by an inability to make a contribution, think of your great sense of accomplishment when you’re able to remotely view the buildings’ “heartbeats” and immediately take action to correct suspected problems…and all while wearing your pajamas!
Stay well! Let us know if you’d like to discuss interval data features in EnergyCAP: acquiring interval data from vendors, connecting to existing metering systems, or installing meters or data logging devices.
Best wishes that you can use your work-from-home time to become a more effective Energy Manager.
