ASME 14414:2015 pdf download Pump system energy assessment
1 Scope
This International Standard sets the requirements for conducting and reporting the results of a pumpingsystem energy assessment(hereafter referenced as “assessment”) that considers the entire pumpingsystem, 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 consumptionof 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, andreporting and documenting assessment findings.
This International Standard is designed to be applied, to open and closed loop pumping systems typicallyused at industrial, institutional, commercial, and municipal facilities, when requested.
This International Standard is focused on assessing electrically-driven pumping systems,which aredominant in most facilities, but is applicable with other types of drivers, such as steam turbines andengines, 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,
caddress 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 howto calibrate test equipmentused duringthe 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 isoperated safely during the data collection phase of the assessment,
i)address issues of intellectual property, security, confidentiality, and safety.

4ldentification of the assessment team, authority and functions
4.1ldentification of assessment team functions
The assessment team composed of knowledgeable personnel shall have members that are assignedresponsibility and authority to carry out the following functions:
resource allocation, in order to:
allocate funding and resources necessary to plan and execute the assessment,exercise final decision making authority on resources,
oversee the eventual participation of non-facility personnel including contracts, scheduling.confidentiality agreements,and statement of work.
coordination, logistics and communications, in order to:
obtain necessary support from facility personnel and other individuals and organizationsduring the assessment,
