Building facility operating status evaluating method and device

Abstract

Reported information is classified as to if it is transient reported information due to a transient factor. Time bands within an evaluating interval that are other than time bands wherein air conditioning control has occurred in response to a transient report are defined as evaluation-applicable time bands, and the average energy consumption in the evaluation-applicable time bands is calculated as an energy consumption that serves as a basis value. Moreover, an average of the historical values of energy consumption in the transient report response-controlled air-conditioning time bands is calculated as an energy consumption to serve as a comparison value, and the difference between this energy consumption that is the comparison value and the energy consumption Wbase that is the basis value is calculated as a possible energy savings, and used as un evaluation index indicating the operating status of an air-conditioning device in terms of energy savings.
