interacting elements to establish an energy policy and energy
objectives, and processes and procedures to achieve those objectives”
(ISO 50001:2011). EnMS starts with an energy policy, defines
energy targets and roles for their achievement, establishes a system
for monitoring energy performances and implements procedures
for continuous improvement in energy performances.
The standard does not define specific performance criteria
related to energy consumption and efficiency (it instead proposes a
management model that contributes to develop and implement the
energy policy and to establish targets, goals and action plans taking
into account legal requirements and information coming from the
analysis and control of energy consumption data) and is useful to
identify requirements that should be adopted. It describes the end
point, but not the path to reach it, and it does not allow an organization
to clearly understand its position on this path. Even if it
shows continuous improvement, an organization can be either
complying with the standard or not, without the possibility to
manage its progressive growth explicitly.
