Thermal Guidelines for Data Processing Environments Fourth Edition 2015
Prior to the 2004 publication of the first edition of Thermal Guidelines for Data Processing Environments, there was no single source in the data center industry for information technology equipment (ITE) temperature and humidity requirements. This book established groundbreaking common design points endorsed by the major information technology original equipment manufacturers (IT OEMs). The second edition, published in 2008, created a new precedent by expanding the recommended temperature and humidity ranges.
This fourth edition takes further steps to increase the energy efficiency of data centers by reducing the requirements for humidification. ASHRAE funded the Electromagnetic Compatibility (EMC) Laboratory at the Missouri University of Science and Technology from 201 1 to 2014 to investigate the risk of upsets or damage to electronics related to electrostatic discharge (ESD). Emphasis was placed on the increase in risk with reduced humidity

The objective of Thermal Guidelines for Data Processing Environments, Fourth Edition, is to do the following:
- Provide standardized operating environments for equipment
- Provide and define a common environmental interface for the equipment and its surroundings
- To Provide guidance on how to evaluate and test the operational health of the data center
- Provide a methodology for reporting the environmental characteristics of a computer system
- Guide data center owners and operators in making changes in the data center environment
- Provide the basis for measuring the effect of any changes intended to save energy in the data center
