Description of Calculation: Total utility costs (including electricity, heating fuel, water, sewer), divided by total square footage of all non-vacant buildings.

Importance of Measure: This measures the efficiency of the district's building utility operations. It may also reflect a district's effort to reduce energy consumption through conservation measures being implemented by building occupants as well as maintenance and operations personnel. Higher numbers signal an opportunity to evaluate fixed and variable cost factors and identify those factors that can be modified for greater efficiency.
