ASHRAE Thermal Guidelines for Data Processing Environments:

Overview:

This document is the first major product developed by ASHRAE TC 9.9 and is the culmination of 3 years of work by over 30 firms.

It provides equipment manufacturers and facility operations personnel with a common set of guidelines for environmental conditions, including:

Standardized operating environments for equipment.


A common environmental interface for the equipment and its surroundings.


Guidance on how to evaluate and test the operational health of the data center.


A methodology for reporting the environmental characteristics of a computer system.

Essentially, the focus of this guideline is on electronic equipment and its interaction with its environment. Since it had an equipment focus, participants in this document included a very strong representation from the major equipment manufacturers.

Purpose:

Proposed ANSI/ASHRAE 127 Standard Update

SPC 127

A committee is being formed to review the standard to insure the standard conforms to the temperature conditions needed for computers and data processing equipment and to review how the standard can be refocused on operating requirements found in a Data Center. These include the need to focus on unit sensible cooling capacities and efficiencies as well as expanding it to include methods of evaluating annual energy use in addition to peak energy use under various outdoor temperature conditions.


The project committee welcomes new participants in this effort. If you are interested please contact Teri Davis at tdavis@ashrae.org for a copy of a membership application form.
