EMS requirements according to
EN ISO 50001:2011
BACS for EMS in buildings
An energy measurement plan, appropriate to the
size and complexity of the organization and its
monitoring and measurement equipment, shall
be defined and implemented.
NOTE Measurement can range from only utility
meters for small organizations up to complete
monitoring and measurement systems
connected to a software application capable of
consolidating data and deliver automatic
analysis. It is up to the organization to determine
the means and methods of measurement.
The organization shall define and periodically
review its measurement needs. The organization
shall ensure that the equipment used in
monitoring and measurement of key
characteristics provides data which are accurate
and repeatable. Records of calibration and other
parameters shall be made.
On-going logging and monitoring of the
significant energy use and affected energy
factors.
Summary of significant energy consumption in
form of key figures.
Compare actual and expected energy
consumption, etc.
Intervene when deviations from expected energy
consumption occur.
Log all significant deviations from expected
energy consumption along with the reasons (if
determined) as well as associated measures.
BACS methods to standardize and anonymize
data (for example, energy performance
indicators etc.) and for benchmarking purposes
(externally and internally).
4.2
4.6.2 Evaluation of legal and other
requirements
At planned intervals, the organization shall
evaluate compliance with legal requirements and
other requirements to which it subscribes related
to its energy use and consumption.
Records of the results of the evaluations of
compliance shall be maintained.
The organization reviews whether BACS is
capable of supporting compliance evaluation
requirements of EMS for building, e.g.:
The organization monitors EMS compliance with
legal obligations and other requirements.
Maintain relevant BACS records to document
compliance, to which the organization
subscribes, relating to significant energy
consumption.
4.3 4.6.3 Internal audit of the EnMS
The organization shall ensure that the EnMS:
- conforms planned arrangements for energy
management including the requirements of this
International Standard;
- conforms with the energy objectives and
targets established;
- is effectively implemented and maintained, and
improves energy performance.
An audit plan and schedule shall be developed
taking into consideration the status and
importance of the processes and areas to be
audited as well as the results of previous audits.
The selection of auditors and conduct of audits
shall ensure objectivity and impartiality of the
audit process.
Records of the audit results shall be maintained
and reported to top management.
The organization reviews how BACS can
support internal audit requirements of EMS for
buildings, e.g.:
BACS provides effective and efficient energy
management program, processes and systems:
opportunities to continual improve the capability
of processes and systems;
data provisioning to apply effective and efficient
statistical techniques;
a suitable information technology platform to
support audit activities.
4.4
4.6.4 Nonconformities, correction, corrective
action and preventive action
The organization shall address actual and
potential nonconformities by making corrections,
and by taking corrective action and preventive
action, including the following:
The organization considers BACS options to
achieve and maintain the nonconformity,
corrective action and preventive requirements of
the EMS for buildings and specifies:
