When energy efficiency measures are applied in industrial enterprises, the implications extend beyond energy savings, generating additional benefits known as productivity benefits. However, there is a knowledge gap concerning experiences in productivity benefits and the extent to which these are recognized by the industry. This study aims to delve into the industrial energy-efficiency measures and productivity benefits, with a specific focus on boiler and steam systems in industrial environments. By exploring the impacts of energy efficiency measures at the operational level, this research aims to provide insights into the broader implications of energy efficiency within industry.
