  http://www.ashrae.org/news/2011/ashrae-introduces-new-liquid-cooled-datacom-environmental-classes

  ""2011 Thermal Guidelines for Liquid Cooled Data Processing Environments"
   creates data center classes for liquid cooling that can enable fulltime
   economizers for a number of applications in many climates, according
   to according to Don Beaty, chair of the Publications Subcommittee of
   ASHRAE's Technical Committee (TC) 9.9, Mission Critical Facilities,
   Technology Spaces and Electronic Equipment."
.....
  "This whitepaper follows an earlier whitepaper released in May 2011,
   "2011 Thermal Guidelines for Data Processing Environments - Expanded
   Data Center Classes and Usage Guidance," which addresses air cooling
   in data centers and created new data center environmental classes
   which expanded the opportunity for chiller-less data centers
   (fulltime economizers)."

Introduction
.....
"Developing these new classes among the commercial IT manufacturers
 in consultation with the Energy Efficient High Performance Computing
 (EE HPC) Working Group (WG) should produce better results since
 the sharing of some critical data among them has proven in the past
 to achieve broader environmental specifications than what otherwise
 would have been achieved."

APPENDIX B. Energy Efficient High Performance Computing Working Group
"The Energy Efficient High Performance Computing (EE HPC) Working Group
 (WG) is an ad-hoc group, with logistics and organizational support
 from the DOE. The WG is open to all HPC practitioners from
 the US National Labs and others involved or interested in HPC.

 The WG efforts were focused on establishing the ideal water supply
 temperatures for the National labs. The activity begins with
 a survey of National Lab locations and respective dry bulb (DB) and
 wet bulb (WB) temperatures extremes."
