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.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
