Introduction
Existing energy management standards often refer to the measurement of energy as an important
improvement of energy performance, but do not detail how a measurement and monitoring plan should
be designed and implemented:
— EN 16247-1:2012, Energy audits: in specific cases an energy audit requires to get specific data
measurement (§ 5-2 b) 5-3, 5-5). An energy measurement plan has to be set up in order to collect
this data. But there are no guidelines given on how to design or implement an energy measurement
plan: The future standard will help to fulfil this step;
— EN 15900:2010, Energy Efficiency Services: the energy efficiency service has to be based on collected
data (4-1 b). If there is not available or reliable data an energy measurement plan is needed;
— ISO EN 50001:2018 states in 6-6: "The organization shall define and implement an energy data
collection plan appropriate to its size, its complexity, its resources and its measurement and
monitoring equipment. The plan shall specify the data necessary to monitor the key characteristics
and state how and at what frequency the data shall be collected and retained." EN 17267 provides
principles for the design and implementation of an energy data collection plan;
— ISO 50006:2014, "Energy management systems — Measuring energy performance using energy
baselines (EnB) and energy performance indicators (EnPI) — General principles and guidance",
provides some recommendation related to measurement (§ 4.2.6.2);
— ISO EN 50015:2014, describes the process of "Measurement and verification" (M & V) to help
organizations determine and validate in a systematic way the improvement of its energy
performance, within specified boundaries. As can be seen in Clause 5.2 [h) k) l) m)], the M&V process
relies upon a number of measurements, without giving the methodology on how to organize the
measurement. To ensure the quality of these measurements (reliability, accuracy as well as
appropriateness) a "measurement plan" is needed.
The measurement and monitoring plan should be considered as a tool to facilitate the operational
implementation of those cited standards.

4 General characteristics of a measurement and monitoring plan
4.1 Purpose of a measurement and monitoring plan
The purpose of the measurement and monitoring plan is to design, apply, use and maintain the
measurement system which enables the organization to:
— measure the energy performance to ascertain that it complies with the targets;
— analyse the causes of potential drifts in energy consumption;
— monitor the relevant parameters of the installation;
— sustain the energy performance gains made over time;
— identify potential improvements.
The measurement and monitoring plan may be used on its own. It also provides practical principles and
guidance on how to collect data for ISO 50001, in line with the requirements stated in its 6-6 section (“The
organization shall define and implement an energy data collection plan appropriate to its size, its
complexity, its resources and its measurement and monitoring equipment. The plan shall specify the data
necessary to monitor the key characteristics and state how and at what frequency the data shall be
collected and retained.").

5 The stages of a measurement and monitoring plan
5.1 General
The organization shall carry out the stages 1 to 6 defined in 5.2 to 5.7 when putting in place a
measurement and monitoring plan, as described in the following figure:
Figure 2 — The stages of a measurement and monitoring plan
12
---------------------- Page: 14 ----------------------
SIST EN 17267:2019
EN 17267:2019(E)
The figure doesn’t imply a linear approach and users of the standard may loop back to a stage in an
iterative process.
5.2 Stage 1: Define context, objectives and constraints
5.2.1 Objectives
— Ensure that the motivations, implications and objectives of organization are clearly defined;
— ensure that the key characteristics of operations that determine energy performance are measured,
analysed and monitored at planned intervals;
— ensure that the organizational, technical and financial contexts will allow the creation and
maintenance of a measurement and monitoring plan.
5.2.2 Context of the measurement and monitoring plan
The measurement and monitoring plan is meant as a tool to help organizations to improve and monitor
their energy performance and support the verification of the savings.
The measurement and monitoring plan should be used for the implementation of an ISO 50001 energy
management system:
— an energy management system in ISO 50001 requires that the key characteristics of energy
performance are measured, monitored and analysed at regular intervals, as part of an energy data
collection plan;
— “measurement and verification” (M&V) methods, as defined in ISO 50015, help the organization
determine and validate in a systematic way the improvement of its energy performance, within
specified boundaries. The M&V process relies upon a number of measurements. To ensure the quality
of these measurements (reliability, accuracy as well as appropriateness) a “measurement and
monitoring plan” is therefore needed.
The measurement and monitoring plan may support the use of other standards relative to energy
management, such as:
— energy audits (as described in EN 16247): an energy audit requires to get specific data measurement;
— energy efficiency services (as described in EN 15900): an energy efficiency service has to be based
on collected data.
However, an organization wishing to deploy a measurement and monitoring plan faces a number of
obstacles, including:
— the design of the plan, defining its content according to the needs and objectives;
— the evaluation of the cost/benefits of implementing the plan, acting as a decision-aid;
— the technical difficulties associated with the implementation of the plan.

EN 17267:2019(E)
5.2.3 Motivations of the organization
The organization shall design its measurement and monitoring plan such that it contributes to the
improvement of its energy performance.
By putting in place a plan, the organization obtains benefits such as:
— improve the monitoring of energy consumption;
— detect anomalies or drifts;
— facilitate operation and maintenance;
— implement a proactive approach to improving energy performance;
— meet the legal requirements and other requirements relative to energy;
— implement the recommendations of the energy audits.
5.2.4 Boundaries of the measurement and monitoring plan
The organization shall define the boundaries of the measurement and monitoring plan, and more
specifically the sites and the zones.
NOTE 1 See Annex A for an explanation on the notion of zones.
NOTE 2 For electrical applications, another way to define boundaries is using the notion of mesh
(see IEC 60364-8-1)
5.2.5 End purpose of measurements
The organization shall define the end-purpose of each measurement within the measurement and
monitoring plan, such as:
— calculate an Energy Performance Indicator (EnPI) (as specified in ISO 50006) and follow its
development over time;
— establish an energy baseline (as specified in ISO 50006);
— verify the savings;
— monitor the energy performance of an equipment, a process or an installation.
Additional measurements of influencing factors are in the scope of the standard, to complete the
information provided by energy meters. Yet it shall be verified that all the measuring points included in
the measurement and monitoring plan are intended to improve the energy performance of the
organization. Parameter measurements that have no direct or indirect influence on energy consumption
are not included in the boundaries of the energy measurement and monitoring plan.
5.2.6 Users of the plan
The organization shall identify the specific needs of each type of user of a measurement and monitoring
plan, including but not limited to:
— top management: defines the organization objectives relative to energy management in general and
energy measurement and monitoring in particular including the budget and priorities;

— energy management team: provides expertise related to energy management, at site or
organizational level. The measurement and monitoring plan is one of the tools he uses to implement
an efficient energy management system. The energy management team is responsible for making
sure the scope of measured data are consistent with energy management objectives;
— operating and maintenance staff: tasked with using the measurement system to check and ensure
efficient operation by taking corrective measures in the event of deviations in energy performance,
by eliminating energy losses and performing corrective and preventive maintenance to reduce
deterioration in energy performance. The operating and maintenance personnel can use the
measurement and monitoring plan for the equipment, process or installation under their
responsibility;
— end-users: these users can include other corporate departments, business experts, contract
managers, EnMS auditors, customers, suppliers, regulating organizations, architects, facility
managers or any other user interested into the energy related data;
— installers and system integrators: are responsible for the design and setup of the measurement
system. They shall make sure the measurement system is working as expected by the plan. They may
be internal or external.
5.2.7 Budget
The organization shall define the budget allocated to the measurement and monitoring plan according to
its objectives and the energy issues at stake. The plan shall be v

Introduction
Existing energy management standards often refer to the measurement of energy as an important
improvement of energy performance, but do not detail how a measurement plan should be
implemented:
— EN 16247-1:2012 - Energy audits: in specific cases an energy audit requires to get specific data
measurement (§ 5-2 b) 5-3, 5-5). An energy measurement plan has to be set up in order to collect
this data. But there are no guidelines given on how to design or implement an energy measurement
plan: The future standard will help to fulfil this step.
— EN 15900:2010 - Energy Efficiency Services: the energy efficiency service has to be based on
collected data (4-1 b). If there is not available or reliable data an energy measurement plan is
needed.
— ISO EN 50001:2011 states in 4-6-1: “an energy measurement plan appropriate to the size and
complexity of the organization and its monitoring and measurement equipment shall be defined
and implemented”. But there are no guidelines given on how to design or implement an energy
measurement plan: The future standard will help to fulfil this requirement.
— ISO EN 50015:2014 describes the process of “Measurement and verification” (M and V) to help
organizations determine and validate in a systematic way the improvement of its energy
performance, within specified boundaries. As can be seen in Clause 5.2 [h) k) l) m)], the M&V
process relies upon a number of measurements, without giving the methodology on how to
organize the measurement. To ensure the quality of these measurements (reliability, accuracy as
well as appropriateness) a “measurement plan” is needed.
The measurement and monitoring plan should be considered as a tool to facilitate the operational
implementation of those cited standards.

4 General characteristics of a measurement and monitoring plan
4.1 Purpose of a measurement and monitoring plan
The purpose of the measurement and monitoring plan is to design, apply, use and maintain the
measurement system which enables the organization to:
— measure the energy performance to ascertain that it complies with the targets;
— analyse the causes of potential drifts in energy consumption;
— monitor the relevant parameters of the installation;
— sustain the efficiency gains made over time;
— identify potential improvements
4.2 Relation between the measurement and monitoring plan and the measurement
system
A measurement system brings together the elements described in Figure 1, according to the needs of
the organization:

oSIST prEN 17267:2018
prEN 17267:2018(E)
4.3 Process to maintain the measurement and monitoring plan
The implementation of the measurement and monitoring plan is an iterative process.
The organization shall put in place a periodic review of its plan in order to reach its objectives.
5 The stages of a measurement and monitoring plan
5.1 General
The organization shall carry out the stages 5.2 to 5.7 when putting in place a measurement and
monitoring plan, as described in the following figure:

oSIST prEN 17267:2018
prEN 17267:2018(E)
5.2 Stage 1: Define context, objectives and constraints
5.2.1 Objectives
— Ensure that the motivations, implications and objectives of organization are clearly defined;
— Ensure that the key characteristics of operations that determine energy performance are measured,
analysed and monitored at planned intervals;
— ensure that the organizational, technical and financial contexts will allow the creation and
maintenance of a measurement and monitoring plan.
5.2.2 Context of the measurement and monitoring plan
The measurement and monitoring plan is meant as a tool to help organizations to improve and monitor
their energy performance and support the verification of the savings.
The measurement and monitoring plan should be used for the implementation of an ISO 50001 energy
management system:
— an energy management system in ISO 50001 requires that the key characteristics of energy
performance are measured, monitored and analysed at regular intervals;
— “measurement and verification” (M&V) methods, as defined in ISO 50015, help the organization
determine and validate in a systematic way the improvement of its energy performance, within
specified boundaries. The M&V process relies upon a number of measurements. To ensure the
quality of these measurements (reliability, accuracy as well as appropriateness) a “measurement
and monitoring plan” is therefore needed.
The measurement and monitoring plan may support the use of other standards relative to energy
management, such as:
— energy audits (as described in EN 16247): an energy audit requires to get specific data
measurement;
— energy efficiency services (as described in EN 15900): an energy efficiency service has to be based
on collected data;
— etc.
However, an organization wishing to deploy a measurement and monitoring plan faces a number of
obstacles, including:
— the design of the plan, defining its content and its according to the needs and targeted objective;
— the evaluation of the cost/benefits of implementing the plan, acting as a decision-aid;
— the technical difficulties associated with the implementation of the plan.
5.2.3 Motivations of the organization
The organization shall design its measurement and monitoring plan such that it contributes to the
improvement of its energy performance.
By putting in place a plan, the organization may obtain benefits such as:
— improve the monitoring of energy consumptions;
12
---------------------- Page: 14 ----------------------
oSIST prEN 17267:2018
prEN 17267:2018(E)
— detect anomalies or drifts;
— facilitate operation and maintenance;
— implement a proactive approach to improving energy performance;
— meet the legal requirements and other requirements relative to energy;
— implement the recommendations of the energy audits.
5.2.4 Boundaries of the measurement and monitoring plan
The organization shall define the boundaries of the measurement and monitoring plan, and more
specifically the sites and the zones.
NOTE 1 See Annex A for an explanation on the notion of zones.
NOTE 2 For electrical applications, another way to define boundaries is using the notion of mesh
(see IEC 60364-8-1)
5.2.5 End purpose of measurements
The organization shall define the end-purpose of each measurement within the measurement and
monitoring plan, such as:
— calculate an Energy Performance Indicator (EnPI) (as described in ISO 50006) and follow its
development over time;
— establish an energy baseline (as described in ISO 50006);
— verify the savings;
— monitor the energy performance of an equipment, a process or an installation.
Additional measurements of influencing factors are in the scope of the standard, to complete the
information provided by energy meters. Yet it should be verified that all the measuring points included
in the measurement and monitoring plan are intended to improve the energy performance of the
organization. Parameter measurements that have no direct or indirect influence on energy
consumption are not included in the boundaries of the energy measurement and monitoring plan.
5.2.6 Users of the plan
The organization shall identify the specific needs of each type of user of a measurement and monitoring
plan, including but not limited to:
— top management: defines the organization objectives relative to energy management in general and
energy measurement and monitoring in particular including the budget and priorities;
— energy manager: provides expertise related to energy management, at site or organizational level.
The measurement and monitoring plan is one of the tools he uses to implement an efficient energy
management system. The energy manager is responsible for making sure the scope of measured
data are consistent with energy management objectives;
— operating and maintenance staff: tasked with using the measurement system to check and ensure
efficient operation by taking corrective measures in the event of deviations in energy performance,
by eliminating energy losses and performing corrective and preventive maintenance to reduce
deterioration in energy performance. The operating and maintenance personnel can use the
13
---------------------- Page: 15 ----------------------
oSIST prEN 17267:2018
prEN 17267:2018(E)
measurement and monitoring plan for the equipment, process or installation under their
responsibility;
— end-users: these users can include other corporate departments, business experts, contract
managers, EnMS auditors, customers, suppliers, regulating organizations, architects, facility
managers or any other user interested into the energy related data;
— installers and system integrators: are responsible for the design and setup of the measurement
system. They need to make sure the measurement system is working as expected by the plan. They
may be internal or external.
5.2.7 Budget
The organization shall define the budget allocated to the measurement and monitoring plan according
to its objectives and the energy issues at stake. The plan shall be validated by the financial sponsors in
the organization, to whom energy managers shall report on the progress of its practical
implementation.
5.2.8 Planning
The energy performance measurement plan may be implemented in steps according to priorities in
order to meet the organization's budgetary constraints and mitigate the project risks.
The organization shall put in place a schedule for the implementation of the measurement plan,
including the most important milestones of the project.
5.2.9 Resources
The organization shall identify the human and material resources necessary for the implementation of
the measurement plan, with the relevant expertise related to:
— design;
— installation;
— metrology;
— acquisition system or resources necessary for manual reading if necessary;
— storage and use of data;
— maintenance.
The organization shall clearly identify a responsible person for the measurement and monitoring plan
and ensure that he/she is competent and available.
The organization shall identify and verify the skills necessary for the application of the measurement
and monitoring plan by its personnel or its service providers.

5.2.10 Criteria to asset the levels of the measurement system
The organization shall assess the appropriateness of its measurement system with respect to its needs.
Three levels (base, medium, high) are defined in Annex B. The levels shall be assessed in accordance
with the following six criteria:
— criterion 1: the ability to quantify the energy consumptions by zone and by energy use;
NOTE 1 The majority of the sites have consumption measurements at the points of delivery. These
measurements are used essentially for billing. Having sub-measurement by zone or by energy use allows finer
analysis and monitoring of energy consumptions and performance.
— criterion 2: the ability to acquire measuring points and relevant variables at a regular frequency;
NOTE 2 To analyse the trend of energy consumptions, the measuring point readings can be taken regularly.
The measuring points can be read manually by operators or automatically by remote reading. Remote reading
generally allows a larger number of measuring points to be read at a higher frequency while controlling costs.
NOTE 3 The identification and quantification of the influencing factors improves and refines the analysis of
variations in energy consumption and therefore in energy performance.
— criterion 3: the ability to transfer the measurement and relevant variables data;
NOTE 4 The time-stamped recording of the readings taken at regular intervals from the different measuring
points allows the detection of variations in energy consumption over time.
— criterion 4: the ability to store measurement and influencing factors data;
— criterion 5: the ability to analyse the collected data;
NOTE 5 Installation monitoring can reveal malfunctions that affect energy performance. To facilitate
monitoring, thresholds and alarms can be put in place on the monitoring parameters. The levels of the
measurement system on a zone, on an energy use or even a measuring point can differ according to the energy
issues at stake, the technical and economic constraints and its energy performance objectives.
— criterion 6: the ability to visualize data and the results from the analysis.
Annex C provides examples of assessment according to the six above-mentioned criteria.
5.2.11 Deliverables
The organization shall provide a note summarizing its objectives and its constraints, the organizational
structure adopted and the implementation schedule and budgets allocated to the measurement and
monitoring plan.
5.3 Stage 2: Assess the existing situation
5.3.1 Objectives
— Draw up the functional inventory (the needs, the data that shall be collected and why);
— draw up the technical inventory (the available data, tools, measurement devices and equipment).

define the energy issues at stake. The organization may carry this study via the collect and analysis of:
— energy bills;
— energy audits;
— buildings or plant design documentation (e.g. energy rating of the building);
— simulations (e.g. thermal simulation for a new building);
— existing measurement system documentation;
— or any other document that it may see fit for that purpose.
