A set of energy use model parameters for each of a plurality of buildings is used to determine a typical set of energy use model parameters for the plurality of buildings. A distance between the typical set of energy use model parameters and the set of energy use model parameters for each of the plurality of buildings is determined. Each distance is compared to a critical value. A building is identified as a candidate for energy conservation measures in response to the distance for the building exceeding the critical value. Energy conservation measures are implemented in the identified building. Implementing energy conservation measures may include replacing existing HVAC equipment in the identified building with new energy-efficient HVAC equipment.
