Catch the Energy Efficiency Rebound!

Energy analysts say there is a “rebound effect” on energy efficiency projects that reduces or negates the financial advantage. The basic argument is that after we make energy efficiency improvements in buildings or cars (or any other system), we tend to use them more so some or all of the savings is lost.

As an example, you might drive your car more if you are getting better gas mileage, thereby using just as much gas and spending just as much money as you would have with your previous gas-guzzling vehicle. Or, if you are putting new energy-saving LED lights in your building, you might also add some fancy lighting to the lobby or outside the building to attract attention, thereby negating some of the savings from simply replacing the existing lighting.

The so-called energy efficiency rebound effect is commonly blamed for 30% loss of expected savings, and sometimes up to 60%. But with Events2HVAC, the rebound effect is 0%.

Events2HVAC pulls data from room schedules that are set based on the demand for space – business conferences, college classes, weddings and parties, concerts, church services, and many other types of events. The people using the space usually have no knowledge of the energy efficiency savings occurring because of Events2HVAC, or any reason to increase their use of the space. If the use of the space increases, it is most likely the result of a natural increase in use that would have occurred with or without Events2HVAC.

Rather than a rebound effect that undercuts expected savings, Events2HVAC has a multiplier effect that allows facilities to save in multiple ways:

  1. Save energy by running HVAC and lighting only in scheduled rooms.
  2. Save money by extending the useful life of your HVAC equipment and lighting systems.
  3. Save time by eliminating redundant data entry related to scheduling HVAC systems.
  4. Save frustration and stress by eliminating human scheduling errors.
  5. Save effort by freeing up facility managers to focus on important projects.

A recent study at Appalachian State University showed that even a small implementation of Events2HVAC can provide a quick return on investment, with a 39.7% savings in electricity. A larger implementation can save even more money by reducing energy use, decreasing labor hours, and extending the useful life of equipment.

So what will you do with your Events2HVAC savings?
