Real-Time Energy Consumption Measurements in Data Centers (ASHRAE Datacom Series Book 9)

Overview

The book is the ninth volume of the ASHRAE TC 9.9 Datacom Series. It is dated 2010, carries product code 90446 and runs to 296 pages according to the catalogue. It is a paid publication, available through the ASHRAE Bookstore or a TC 9.9 Datacom Encyclopedia subscription. The text itself was not read here; only catalogue and ASHRAE Handbook descriptions were used.

According to the Handbook description, the book's core subject is the instrumentation and monitoring of key power and cooling subsystems. Data centre energy performance can only be judged from data gathered at the right points and at sufficient frequency, so the book concentrates on how to build the measurement infrastructure. A second important aspect is its worked examples. It includes examples of using energy consumption data to calculate PUE, letting the reader follow the chain from metering points to a metric end to end. Which measurement points PUE rests on directly affects how trustworthy the reported value is.

Because the contents were not read directly, nothing can be said here about chapter structure, measurement accuracy or device recommendations. The recorded information is limited to the scope description, page count, publication year and the presence of PUE examples. For designers its value is in prompting the question of which power and cooling points must be metered when preparing a metering plan. In projects that will report by PUE category, this means fixing the meter points during design.

Key points

1. ASHRAE Datacom Series Book 9, product code 90446.
2. Listed as a 2010 publication.
3. 296 pages according to the catalogue record.
4. Guides instrumentation and monitoring of key power and cooling subsystems.
5. Includes examples of using energy consumption data to calculate PUE.

Using it in design

• In a metering plan generator, define at design stage the meter points needed for PUE category reporting.
• Build meter points in the power chain and cooling subsystems into the project from the start; retrofitting is costly.
• When reporting PUE, document which measurement points it relies on.
• Consult the book itself for detailed measurement method; this record only describes its scope.

Who should read it

Design engineers and operations teams establishing energy monitoring and PUE reporting.
