Learn how to compare buildings in 5 minutes.
Here at the Energy Conservation Office, we like to call ourselves energy nerds. In this post we’d like to emphasize that you don’t have to be an energy engineer to be an energy nerd. Furthermore, you don’t need to have a technical background to understand the energy data on our energy dashboard.
Why do we we use EUI?
An EUI is a great way to compare how buildings are using energy because an annual energy use is divided by the building’s size in square feet. This gives you energy per square foot and levels the playing field, so to speak.
We’ll compare the Activities and Recreation Center (ARC) and the Student Community Center (SCC):
First, let’s compare the square footage of the buildings. As you can see, the ARC is almost 3 times as large as the SCC!
To figure out the EUI of each building, we take the annual energy usage (in kBtu) from the building’s energy meters and divide it by the square footage.
Although the ARC is significantly larger than the SCC, their EUI values are surprisingly close!
Thirsty for more EUI knowledge? Get on the energy dashboard, CEED, where you can make all sorts of astounding building comparisons.
Any ideas why the ARC has an EUI close to the SCC’s, even though its three times as large? Stay tuned to find out in our next EUI post.
