BS EN ISO 11011:2015

What is BS EN ISO 11011 - Compressed air energy efficiency about?  

BS EN ISO 11011 sets requirements for conducting and reporting the results of a compressed air system assessment (hereafter referenced as an “assessment”) that considers the entire system, from energy inputs to the work performed as the result of these inputs. 

BS EN ISO 11011 considers compressed air systems as three functional subsystems: 

• Supply which includes the conversion of primary energy resources 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 

BS EN ISO 11011 sets requirements for 

• Analysing the data from the assessment 
• Reporting and documentation of assessment findings 
• Identification of an estimate of energy saving resulting from the assessment process 

BS EN ISO 11011 identifies the roles and responsibilities of those involved in the assessment activity. BS EN ISO 11011 provides indicative information in Annexes B, C, D, and E of the type of 

data to be collected to assist in a successful assessment. The information provided is not exhaustive and therefore is not intended to restrict the inclusion of other data. The form and presentation of the information given in the annexes are also not intended to restrict the manner of presentation of the reporting to the client. 

Who is BS EN ISO 11011 - Compressed air energy efficiency for? 

BS EN ISO 11011 on compressed air energy efficiency is useful for: 

• The transportation industry 

• The service industry 
• The agriculture industry 
• The automotive industry 
• General manufacturing 

Why should you use BS EN ISO 11011 - Compressed air energy efficiency?  

BS EN ISO 11011 has been developed with reference to available documentation relating to energy assessment of compressed air systems. BS EN ISO 11011 is produced to support the objectives of energy management for those organizations utilizing compressed air and wishing to improve the energy efficiency of such systems. Remembering the words of Lord Kelvin who said in 1883, “If you cannot measure it, you cannot improve it”, this BS EN ISO 11011 aims to assist with measurement and provide the knowledge to enable improvement. The prime consideration for any compressed air system is the ability to generate air with the least amount of energy. Having done this, the next consideration is to transmit energy from the point of generation to the point of use with the least loss. The final consideration is to eliminate waste and use the least amount of air for the production process. 

BS EN ISO 11011 uses specialty terms that relate the needs of assessment activities to those of compressed air systems. Many terms will appear new to the users of this BS EN ISO 11011 who are familiar with general compressed air terms. A general introduction to energy assessment is given in Annex A.
