Energy Management System (EnMS)
Domain 2 tests the structural requirements of clauses 4, 5, 7.5 and 8 - the framework that surrounds the energy-specific planning and checking clauses.
Context, interested parties, scope (clause 4)
Determine external and internal issues relevant to purpose; determine interested parties and their relevant requirements; define the scope, documented and available to interested parties, considering issues, requirements and organizational boundaries; then establish, implement, maintain and continually improve the EnMS.
Leadership and policy (clause 5)
Top management is accountable. The energy policy commits to continual improvement of energy performance and of the EnMS, to ensuring availability of information and resources, to fulfilling legal and other requirements, and to supporting procurement of energy-efficient products and services and design for energy performance improvement. It is documented, communicated internally and available to interested parties. Roles, responsibilities and authorities are assigned (5.3); the 2011 management representative role no longer exists.
Documentation and operations (7.5, 8)
Documented information covers what the standard requires plus what the organization decides is necessary, with control ensuring availability and protection. Operational control sets criteria for SEUs, maintains facilities, manages change and controls outsourced processes; design and procurement build energy performance into future assets.
Worked example
A manufacturer excludes a leased warehouse from scope although it holds 30% of stock and consumes energy. The exclusion is only defensible if the boundary is justified and consistent with the energy review and data; excluding a significant energy user while its consumption still appears in reported figures contradicts itself.
Traps
A policy promising EnMS improvement but silent on energy performance; a scope written for the certificate rather than for the energy review; operational control procedures not linked to any identified SEU.
