  "Standard 90.1 has been a benchmark for commercial building energy
   codes in the United States and a key basis for codes and standards
   around the world for more than 35 years."

  "This 2010 edition has been expanded to include new features, an
   expanded scope, and more detailed requirements, as well as
   incorporating changes from more than 100 addenda."

[san-tech][02261] データセンター効率規格についての議論と PUE承認

"Setting efficiency goals for data centers",
 April 12, 2010, Google Public Policy Blog

  "Recently, the American Society of Heating, Refrigerating and
   Air-Conditioning Engineers (ASHRAE) added data centers to their
   building efficiency standard, ASHRAE Standard 90.1. This standard
   defines the energy efficiency for most types of buildings in America
   and is often incorporated into building codes across the country."
  "We believe that for data centers, where the energy used to perform
   a function (e.g., cooling) is easily measured, efficiency standards
   should be performance-based, not prescriptive. In other words, the
   standard should set the required efficiency without prescribing the
   specific technologies to accomplish that goal."
  "Unfortunately, the proposed ASHRAE standard is far too prescriptive.
   Instead of setting a required level of efficiency for the cooling
   system as a whole, the standard dictates which types of cooling
   methods must be used."
  "Thus, we believe that an overall data center-level cooling system
   efficiency standard needs to replace the proposed prescriptive
   approach to allow data center innovation to continue." ....
  "As leaders in the data center industry, we are committed to
   aggressive energy efficiency improvements, but we need standards that
   let us continue to innovate while meeting (and, hopefully, exceeding)
   a baseline efficiency requirement set by the ASHRAE standard."

"Facebook Urges Changes on Cooling Standards", October 4th, 2010

  "Facebook has joined the chorus of major data center operators
   opposing new guidelines on data center cooling being considered by
   a key industry standards body. The debate focuses on technical
   details of a standard being proposed by the Society of Heating,
   Refrigerating and Air-Conditioning Engineers (ASHRAE)."

未だ入手してないので解りません (後追い記事・意見等が見あたりません)。
