EMS requirements according to
EN ISO 50001:2011
BACS for EMS in buildings
- identify other relevant variables affecting
significant energy uses;
- determine the current energy performance of
facilities, equipment, systems and processes
related to identified significant energy uses;
- estimate future energy use and consumption;
c) identify, prioritize record opportunities for
improving energy performance.
NOTE Opportunities can relate to potential
sources of energy, use of renewable energy, or
other alternative energy sources, such as waste
energy.
The energy review shall be updated at defined
intervals, as well as in response to major
changes in facilities, equipment, systems, or
processes.
2.4.4 4.4.4 Energy baseline
The organization shall establish an energy
baseline(s) using the information in the initial
energy review, considering a data period
suitable to the organization's energy use and
consumption. Changes in energy performance
shall be measured against the energy
baseline(s).
Adjustments to the baseline(s) shall be made in
the case of one of the following:
- EnPIs no longer reflect organizational energy
use and consumption, or
- there have been major changes to the process,
operational patterns, or energy systems, or
- according to a predetermined method.
The energy baseline(s) shall be maintained and
recorded.
BACS gathers the necessary data (monitoring
function) in order to build baselines.
BACS might need to normalize data according to
given parameters (e.g. heating degree days).
BACS might determine performance indicators
that adapt to the actual usage in order to take
automatically actual usage of space into
account.
2.4.5 4.4.5 Energy performance indicators
The organization shall identify EnPIs appropriate
for monitoring and measuring energy
performance. The methodology for determining
and updating the EnPIs shall be recorded and
regularly reviewed.
EnPIs shall be reviewed and compared to the
energy baseline as appropriate.
BACS might determine performance indicators
that adapt to the actual usage in order to take
automatically actual usage of space into
account.
2.4.6
4.4.6 Energy objectives, energy targets and
energy management action plans
The organization shall establish, implement and
maintain documented energy objectives and
targets at the relevant functions, levels,
processes or facilities within the organization.
Time frames shall be established for
achievement of the objectives and targets.
The objectives and targets shall be consistent
with the energy policy. Targets shall be
consistent with the objectives.
The organization determines BACS objectives,
targets and program that are consistent with the
energy policy and the significant energy aspects
of buildings, e.g.:
Energy saving targets to be achieved by
applying BACS.
Apply BACS as tool support the EMS in
achieving and maintaining its strategic and
operative aims.
