Evaluation énergétique des systèmes de pompage (ISO/ASME 14414:2015)
L'ISO/ASME 14414:2015 pose les exigences de réalisation et de compte rendu d'une évaluation de l'énergie d'un système de pompage (désignée par la suite «évaluation») qui considère l'ensemble de l'installation de pompage depuis les points d'introduction de l'énergie dans l'installation jusqu'au travail fourni par l'installation à l'aide de cette énergie.
L'objectif d'une évaluation énergétique d'un système de pompage est de déterminer la consommation d'énergie actuelle d'un système existant et d'identifier les manières d'augmenter le rendement du système.
Ces exigences concernent
l'organisation et le pilotage d'une évaluation,
l'analyse des données de l'évaluation, et
la rédaction du compte-rendu de fin d'évaluation et du dossier documentaire associé.
L'ISO/ASME 14414:2015 est conçue pour être appliquée aux systèmes de pompage en boucle ouverte et en boucle fermée, utilisés dans des installations industrielles, institutionnelles, commerciales et municipales, lorsque c'est demandé.
L'ISO/ASME 14414:2015 met la priorité sur l'évaluation des systèmes de pompage entraîné par moteur électrique, qui sont majoritaires dans les installations. Elle est toutefois applicable à d'autres types d'entraînements, par exemple turbines à vapeur et moteurs thermiques, et entraînements tels que les dispositifs à courroie.

ISO/ASME 14414:2015(E)
Introduction
Pumping systems account for a significant portion of a facility’s energy consumption in many industries.
In the majority of pumping systems the energy added to the working liquid by the pump is much greater
than is required by the process. The excess energy added to the system (e.g. due to throttled control
valve) increases heat, noise and vibration but also can bring the system’s maintenance costs. The
addition of excessive energy to the system often results in over-sizing piping system components such
as pumps, process components, and control valves, resulting in an increase in capital costs.
This International Standard provides a method to assess pump systems, to identify and quantify pump
system energy consumption reduction opportunities and reliability improvement opportunities. It gives
a common definition for what constitutes an assessment for both users and providers of assessment
services. Its objective is to provide clarity for these types of services which have been variously described
as energy assessments, energy audits, energy surveys and energy studies.
In all cases, systems (energy-using logical groups of equipment organized to perform a specific
function) are analysed through various techniques such as measurement, resulting in identification,
documentation and prioritization of energy performance improvement opportunities.
When contracting for assessment services, facility personnel may use this International Standard to define
and communicate their desired scope of assessment activity to third party contractors or consultants.
This International Standard is expected to contribute to decreased energy consumption and consequently
to decreased carbon footprint.
This International Standard includes the required assessment report content in Annex A. It gives
examples of efficient system operation and energy reduction opportunities in Annex B, information on
competencies and experiences welcomed to perform audit in Annex C, guidelines for analysis software
in Annex D, a typical example of pre-screening worksheet in Annex E, information on specific energy
in Annex F, information on the concept of parasitic power in Annex G and examples of pumping system
efficiency indicator in Annex H.
This International Standard is developed within the framework of ISO 50001, ISO 50002 and ISO 50003.

INTERNATIONAL STANDARD
Pump system energy assessment
1 Scope
This International Standard sets the requirements for conducting and reporting the results of a pumping
system energy assessment (hereafter referenced as “assessment”) that considers the entire pumping
system, from energy inputs to the work performed as the result of these inputs.
The objective of a pumping system energy assessment is to determine the current energy consumption
of an existing system and identify ways to improve system efficiency.
These requirements consist of
— organizing and conducting an assessment,
— analysing the data from the assessment, and
— reporting and documenting assessment findings.
This International Standard is designed to be applied, to open and closed loop pumping systems typically
used at industrial, institutional, commercial, and municipal facilities, when requested.
This International Standard is focused on assessing electrically-driven pumping systems, which are
dominant in most facilities, but is applicable with other types of drivers, such as steam turbines and
engines, and drives such as belt.
The International Standard does not
a) specify how to design a pumping system,
b) give detailed qualifications and expertise required of the person using the International Standard
although provides a list of body of knowledge in Annex C,
c) address the training or certification of persons,
d) specify how to implement the recommendations developed during the assessment, but does include
requirements for an action plan,
e) specify how to measure and validate the energy savings that result from implementing assessment
recommendations,
f) specify how to make measurements and how to calibrate test equipment used during the assessment,
g) specify how to estimate the implementation cost or conduct financial analysis for recommendations
developed during the assessment,
h) specify specific steps required for safe operation of equipment during the assessment. The facility
personnel in charge of normal operation of the equipment are responsible for ensuring that it is
operated safely during the data collection phase of the assessment,
i) address issues of intellectual property, security, confidentiality, and safety.

during an assessment (e.g. the failure of a computerized records system).
4.8 Initial Data Collection and Evaluation
4.8.1 General
Before the start of the assessment, the initial data collection shall be made. To expedite the process,
precollection data are optional.
NOTE This information is used in all assessment phases.
4.8.2 Initial facility specialist interviews
The assessment team shall collect information on operating practices and any specific operating
considerations that affect energy use for the equipment through contact with personnel and specialists.
The assessment team shall also have access to facilities personnel who understand connected systems
that will be influenced by changes made to the pumping system.
4.8.3 Energy project history
The assessment team shall collect and review information on energy saving projects, assessments,
audits, baselines, or benchmarking already conducted for the pumping systems being assessed.
4.8.4 Energy cost
The assessment team shall collect cost data including electricity cost per kWh, or other similar terms,
considering all charges such as demand charges, peak rates, time-of-the-day rate and any other costs up
to the point of use. Where necessary, appropriate costs should be assigned to onsite generated electricity.
These costs should be used in subsequent analyses. If electricity is generated on site the avoided cost or
potential sales cost of the energy should be used.
The assessment team shall agree on the period during which the costs are considered valid.
The assessment team should also consider issues such as demand charges and trends to identify
situations not made obvious by the use of average values.

ISO/ASME 14414:2015(E)
From this information, the assessment team shall determine an average annual energy cost per kWh
over the previous 12 months.
If a facility has established a marginal cost for energy, it may be used in the energy cost saving calculation
4.8.5 Initial system data
The assessment team shall:
— define the functional needs of the system(s);
— identify high energy consumption equipment;
— identify control method(s);
— identify throttle control systems;
— identify high, low or negative static head systems;
— identify inefficient devices (obvious signs of disrepair or incorrect operation);
— identify lower mean time before failure (MTBF) pump systems, which generally indicate poor
efficiency operation (see Annexes F and H);
— identify small power input systems that have significant influence on facility reliability and
efficiency. All of them shall be considered, not because of their energy consumption but for the
consequence on the efficiency of the whole facility.
4.9 Objective check
Prior to conducting the assessment, the assessment team shall ensure that the action plan meets the
stated assessment objectives.
The action plan of assessment and the objectives shall be reviewed for relevance, cost-effectiveness, and
capacity to produce the desired results.
5 Conducting the Assessment
5.1 Assessment Levels
5.1.1 General
Depending on the needs of the host organization, one or more of the levels of assessment given in Table 1
shall be selected.

ble operating conditions
NOTE 1 A level 1 assessment is a qualitative review with possible quantitative elements intended to determine the potential
for significant energy savings based on further assessments and to identify specific systems that merit a greater level of
attention.
NOTE 2 A level 2 assessment is a quantitative review intended to determine energy consumption and potential savings
based on measurement of a single steady-state operating condition requiring a single set of measurements.
NOTE 3 A level 3 assessment is a quantitative review that takes varying system demands into account by monitoring
the system over a time span long enough to capture the various operating conditions which require their own set of
measurements.
Depending on the level of assessment, data shall be collected in accordance with Table 2.
5.1.2 Level 1 assessments
Level 1 assessment shall include gathering of system information for pumping systems considered for
evaluation within the scope of the assessment.
Level 1 assessment shall start with the pre-screening.
During the pre-screening, the control methods for the different systems shall be noted. It shall be
determined which systems are best suited for a closer evaluation. It should also be noted if changes to
the pump system will affect other systems, thereby introducing constraints on potential optimization
strategies for the pump system.
As much information as practical should be collected during the level 1 assessment.
The availability at the facility of some types of data (see 5.5) should also be reported during the level 1
assessment even if it is not collected.
A pre-screening worksheet shall be used to assist in this pre-screening exercise. A typical example of
worksheet to aid in the data collection process is given in Annex E.
In general, the steps taken during the pre-screening shall include the following:
a) sort by driver size, annual operating hours, and estimated energy cost;
b) focus on centrifugal pumps operating at fixed speed;
c) focus on pumping systems that throttle and recirculate for flow control;
d) look for energy-waste symptoms such as large difference in supply and demand, commonly achieved
through valve throttling and by-pass flows (see 5.5.5);
e) identify inefficient pumping systems via maintenance and operational staff interviews and review
of maintenance records;
f) select for assessment those systems that appear most likely to exhibit savings potential.

ISO/ASME 14414:2015(E)
From this information the assessment team shall make estimates regarding the potential for energy savings
in each system and shall select the pumping systems that meet the criteria for level 2 or level 3 assessments.
5.1.3 Level 2 assessments
Level 2 assessments shall be performed when it is clear that the observed operating conditions are
representative for the operation of the systems and the changes in operating condition are small or
non-existent.
Level 2 assessments shall be performed using data taken from the facility information systems, in paper
or electronic format, or by using portable measuring devices. The measurements shall cover a limited
amount of time, thus giving a snapshot of the operating conditions at the time of measurement.
5.1.4 Level 3 Assessments
Level 3 assessments shall be made on pumps systems where conditions vary substantially over time.
For such systems, the assessment team shall record the system performance data over the time period
or capture data at the extreme duty points. This activity shall be associated with more extensive use of
in situ monitoring to ensure that the operating conditions can be accurately determined at the various
duty points (i.e. design point, normal, rated, maximum and minimum flow rates). The monitoring shall
be made by connecting transducers to data logging equipment and recording the sensor output, or in
some facilities, where historical information is stored, the relevant information should be downloaded
from the facility information system.

5.2 Walk Through
A walk through is required for level 2 and 3 assessments and may be required for some pumping systems
undergoing a level 1 assessment.
The walk through shall entail examination throughout ensuring that the information provided to the
assessment team reflects the configuration of the existing systems.
For the pumping systems undergoing level 2 and 3 assessments, after the walk through is completed, the
information listed in 5.5 shall be collected using the methodologies specified in 5.6.
All components of the system shall be considered and pertinent information such as valve locations,
locations of available pressure taps, flow meters, valve positions etc. should be noted.
During the walk through, information about the control methods for the different systems such as valve
settings should be noted.
The assessment team shall also identify any existing conditions that are often associated with inefficient
pumping system operation.
These conditions may be identified through the following potential indicators:
1)
a) pumping systems where significant throttling takes place
