Finding your office’s energy hogs July 29th, 2014

Monitoring energy hogs

To find your office energy hogs you must measure them. The U.S Department of Energy reports that 15-20% of our electric bills come from items that are left plugged in when they are not in use, or items that are in standby mode. By using a Belkin Conserve Insight Energy-Use Monitor or a Kill-A-Watt device, you can calculate how much money your office equipment costs to operate – by the day, week, month, or year.



The devices take two types of measurements

  • Idle load – when a device is plugged in but not running (example: a microwave is plugged in but not in currently cooking your lunch)
  • Operational load – when the microwave is cooking your lunch

Why do we care about kWh?

The devices give us an understanding of plug loads broken down by each individual appliance or device. This data is useful in determining how much money is being spent per appliance. By taking the amount of watts over a period of time multiplied by the electricity rate for that market we can determine the amount of money spent on each piece of equipment.

Using a Belkin Conserve Insight Energy-Use Monitor or a Kill-A-Watt device is easy

  • Unplug your electrical device
  • Plug in the monitoring device into the outlet
  • Plug in your electrical device into the monitoring device
  • Read the measurements on the LED screen
  • Input the data into the Energy-Hogs-Calculator (optional)
