"The intent of this publication is to provide the reader with detailed information on the design of datacom facilities that will aid in minimizing the life-cycle cost to the client and to maximize energy efficiency in a facility to align with ASHRAE's stated direction to lead the advancement of sustainable building design and operations"--Provided by publisher.

The second edition of this guide to datacom facility energy efficiency, prepared by Technical Committee 9.9 of the American Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE), is designed for IT professionals and facility designers who need to control energy costs and efficiency through sustainable building practices and operations. This reference volume contains ASHRAE standards and recommendations for environmental criteria, mechanical equipment, economizer cycles, airflow distribution, total cost of ownership and emerging technologies. This new edition contains updated information on the recommended temperatures at equipment inlets inside datacom facilities. Annotation ©2009 Book News, Inc., Portland, OR (booknews.com)
