Abstract: A system and method are provided for implementing business and operational intelligence for building owners or operators regarding energy use by climate control systems in the building. Integrated monitoring, analysis, adjustment and control are provided regarding (1) operation of environmental condition control systems; (2) operating efficiency factors associated with the environmental condition control systems; (3) operating efficiency factors associated with support components, including ducting, supporting the environmental condition control systems; and (4) operating efficiency factors associated with the operating envelope of the structures within which the environmental condition control systems are operated, including building envelope inefficiencies, operating inefficiencies, and airflow inefficiencies.
