Discussion Points
What is driving the emphasis on energyefficiency in the IT/Data Center/High Techsector?
What’s happening on the ground withPG&E, leading high tech companies, andutilities across the nation.
What are the likely developments in thenear term.

Let’s Look at High Tech…
PG&E serves Silicon Valley – almost all of theindustry heavyweights have a presence there
They mostly operate office space and someresidual clean rooms
Mostly, the focus is on data centers

…in Northern California
A total load of 400-500 mW (2.5% of total)
“Enterprise” centers are known
“Corporate” centers are hidden
“Closet” servers are invisible
Key issue for enterprise and some corporatedata centers: space cooling power
Situation so dire, that the industry is moving to…

Here’s the Data Center!

Response to Power/Space/Cooling
“Efficiency” comes to the forefront, but it is largelydue to growth and constraints, notfor environmental responsibility.
Proof Point 1:Companies chasing cheap power locations
Proof Point 2:Old design habits are dying hard (or hardly dying)

What PG&E Offered pre-2006
Audits, incentives that addressed coolingsystems only:
High-efficiency equipment(chillers, pumps, fans, etc.)
Air- and water-side economizers VFD’s
What we were missing:
Anything having to do with operations “insidethe white room”

What We Were Missing
Energy use in a high-performance data center (LBNL/PG&E Study)
HVAC30%
LightingOther12%
Servers &Data Equipment
55%
fans, compressors,and others
3%

More Importantly
The Information Technology managersrun the show at data centers, not facilitymanagers.
Programs and services that address coolingonly address one aspect of the challengesfacing these customers.
