AFCON Predictions (2006)
 By 2010, more than half of all data centers will have to
relocate to new facilities or outsource some applications
 Over the next five years power failures and limits on power
availability will halt data center operations at more than
90% of all companies
 By 2010, Text here 70% of all data centers will utilize some

form of grid computing or other virtual processing
 Within the next five years, 1/4 of all data centers will
experience a business disruption serious enough to affect
the entire company’s ability to continue business-as-usual

Metrics (by The Green Grid)
Power Usage Effectiveness (PUE):
PUE = Total Facility Power ÷ IT Equipment Power

and its reciprocal, the DCiE is defined as:
DCiE = 1÷ Text here = (IT Equipment Power ÷ Total Facility
Your PUE Your Text here
Power) x 100%

Average DC: PUE = 2.0-3.0
Best practice DC = 1.3-1.6
State of Art DC = 1.2

Denmark: 20% of total energy use is from wind turbines
Iceland: 50% of total energy use is from geothermal
sources
Israel: 3% of total energy use is from solar energy (water

Thermal Energy Storage

Extra-Pak Ice Coils are used in thermal energy storage for
buildings 30,000 square feet or larger, industrial process
cooling, and data centers
The design and layout of the elliptical, galvanized steel
coils increase the amount of ice that can be stored in a
given area here

Low temperature cooling water (1°C/34°F) supplied to
an existing building loop can add 20% more cooling
capacity

Thermal Energy Storage -Projects

Matam –Haifa (55,000 m2): Design –IES, investment: 1$M,
estimated savings: 150,000$ year
 Israel Building –Carmiel (20,000 m2): Design –Articom,
investment: 680,000 ₪, estimated savings: 39,000 ₪ a
year
Most common in office and public buildings
No activity in Israeli IT –few pilots so far.
Drawbacks:
• Lack of experienced support
• Not reliable enough
