"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)."
