#"energy efficiency"=("useful energy")/("total energy")#
Multiply result by 100 for a percentage.

Explanation:

For a building, the #"total energy"# is the total amount of energy supplied to the building. The #"useful energy"#, is the amount of energy from that which is put in, which is used in a useful manner, or in other words, isn't wasted.
If you have access to the appropriate data then this should be simple to calculate.
