EPA ENERGY STAR®
EPA is working with interested parties to identify ways in which energy efficiency can be measured, documented, and implemented in datacenters and equipment, especially servers. EPA's current initiatives in this area include:
The Green Grid, Datacenter Maturity Model
The Green Grid has developed the Data Center Maturity Model (DCMM) and associated white paper
to outline capability descriptors by area such that users can benchmark
their current performance, determine their levels of maturity, and
identify the ongoing steps and innovations necessary to achieve greater
energy efficiency and sustainability, both today and into the future.
The maturity model touches upon every aspect of the data center
including power, cooling, compute, storage and network. The levels of
the model outline current best practices and a 5-year roadmap for the
The Green Grid - DATA CENTER EFFICIENCY AND IT EQUIPMENT RELIABILITY AT WIDER OPERATING TEMPERATURE AND HUMIDITY RANGES
Times have changed, have your data center cooling policies changed?
Long known for computer performance benchmarks, SPEC provides a benchmark that evaluates the power and performance characteristics of volume server class and multi-node class computers.
APC Cooling Strategies for Wiring Closets and Small (server) Rooms
Cooling for IT wiring closets (and small server rooms) is rarely planned and typically only implemented after failures or overheating occur. Historically, no clear standard exists for specifying sufficient cooling to achieve predictable behavior within wiring closets. An appropriate specification for cooling IT wiring closets should assure compatibility with anticipated loads, provide unambiguous instruction for design and installation of cooling equipment, prevent oversizing, maximize electrical efficiency, and be flexible enough to work in various shapes and types of closets. This paper describes the science and practical application of an improved method for the specification of cooling for wiring closets.

Emerson Network Power - Five Strategies for Cutting Data Center Energy Costs Through Enhanced Cooling Efficiency
As electricity prices and IT power consumption continue to rise, IT-related energy costs are getting increased scrutiny. Cooling accounts for approximately 37 percent of electricity usage within a well-designed data center and, in many cases, represents a significant opportunity tor educe IT energy costs. This paper presents five strategies for increasing data center cooling efficiency.

APC - Electrical Efficiency Modeling for Data Centers
Conventional models for estimating electrical efficiency of data centers
are grossly inaccurate for real-world installations. Estimates of
electrical losses are typically made by summing the inefficiencies of
various electrical devices, such as power and cooling equipment. This
paper shows that the values commonly used for estimating equipment
inefficiency are quite inaccurate. A simple, more accurate efficiency
model is described that provides a rational basis to identify and
quantify waste in power and cooling equipment.

Turning Challenges into Opportunities in the Datacenter
Currently, data centers consume a little over one percent of the power in the United States annually. Some large data centers draw as much energy as a small town. These figures continue to rise as compute needs grow, density increases, and power and cooling demands climb. As a result, many data centers are reaching their full capacity sooner than expected.
Five Ways to Maximize Web Tier Efficiency
The Web tier consists of the servers and applications that interface most directly with the client in the delivery of Internet services. These front-line servers typically outnumber other data center servers by as much as a factor of five. Consequently, it’s also the area in which great cost savings can be achieved through energy-saving improvements.
