-      * + 
 +  - First gather your utility bills 
 +  - Determine the area square footage of your building 
 +  - Convert your total electricity consumption from kilowatt-hours (kWh) to thousand British Thermal Units (kBTU)  
 +  - Convert your total gas consumption from therms to thousand British Thermal Units (kBTU) 
 +  - Add electricity and gas together (both in kBTU) and then divide by your building'​s square footage 
 +  - [[http://​www.archtoolbox.com/​sustainability/​energy-use-intensity.html|Click this link for an example]] 
 +  - You can use the EUI number to compare your building to others and also compare your own building to itself each month 
 +  - You should see the EUI increase in summer (more cooling) and winter (more heating) but decrease in swing months where the weather is more comfortable 
 +  - You can also determine the EUI for a year instead of each month, this is a greater average and should change less from year to year
