ISO 11011:2013 sets requirements for conducting and reporting the results of a compressed air system assessment that considers the entire system, from energy inputs to the work performed as the result of these inputs.

ISO 11011:2013 considers compressed air systems as three functional subsystems: supply which includes the conversion of primary energy resource to compressed air energy; transmission which includes movement of compressed air energy from where it is generated to where it is used; demand which includes the total of all compressed air consumers, including productive end-use applications and various forms of compressed air waste.

ISO 11011:2013 sets requirements for analysing the data from the assessment, reporting and documentation of assessment findings, and identification of an estimate of energy saving resulting from the assessment process.

ISO 11011:2013 identifies the roles and responsibilities of those involved in the assessment activity.
