manufacturers are integrated for a project
● Power and cooling equipment (other than heat
rejection) is located indoors
● System performance is predicted by analysis
● Controls are created for the project
● Management software is customized for the project
● Cooling is by CRAC/CRAH units located in the IT
room
● Air is distributed under floor via vented tiles
● Outdoor heat rejection via dry cooler, condensor, or
cooling tower
Used in over 90% of installed data centers
Still used in over 80% of new data centers

6. Modular power and cooling plants defined
● End-to-end power and cooling systems are pre-engineered and
pre-manufactured
● Standard building blocks are available
● Modules may be internally fault tolerant, and can be combined to
achieve redundancies
● Equipment arrives in pre-packaged modules, such as skids,
containers, or kits
● System performance is guaranteed by spec
● Controls are standard
● Management software is standard for the modules
Standardization is responsible for many of the benefits,
modularity is the key enabler of standardization

23. 7+
Reasons why Facility Modules
23
Schneider Electric

24. Reason #1: Economizer regulations
● ASHRAE, LEED, and local regulations require economizer modes
Old model: Economizer assists mechanical plant, when possible
New model: Mechanical plant assists economizer, when needed.
● Maximization of free cooling is a complex design and control problem,
difficult to achieve in a unique design
● An integrated design, that considers IT supply temperatures and
airflows, load factors, and ambient conditions is best achieved in a
standardized, pre-engineered system
Adding an economizer to a data center is like adding a
turbocharger to a car: one-off attempts are not likely to
perform well
24
Schneider Electric

25. Economizer mode becomes dominant
Hours where economizer mode
carries 100% of the load
Air-air heat exchanger technology
Isolated from outdoor air; not fresh air
Economizer carries part of load for remaining time
IT inlet 80.6 degrees F
Cooling plant at 2/3 rated load
25
Schneider Electric

26. Reason #2: IT Power Management
● Power management functions in IT equipment will play a major
role in reducing overall energy use of data centers
Old model: Long term adaptations to slow changes in load
New model: Cooling plant optimizes for wide swings in IT load
● Traditional plant design responds through interventions (moving
tiles, turning equipment on and off, adding equipment)
● An optimizing cooling plant adapts to changing load and airflow
requirements by design
Dynamic power variation makes it much more complicated
to predict performance and successfully implement a
unique traditional design without gross over-provisioning
26
Schneider Electric

27. Reason #3: Speed of deployment
● Modularity is not automatically faster
● Modularity allows standardization. It is standardization that makes
cycle time faster
Old model: 18 month design-build-commission cycle
New model: 4 month order-install cycle. Design is off-the-shelf.
Systems mainly pre-commissioned.
● Eventually standard power and cooling modules will be inventory
items
Buy a standard car is faster than build your own unique car
27
Schneider Electric

28. Reason #4: Scale – Capacity, redundancy, ..
● Oversizing remains a major drag on the data center industry
● It is the dominant contributor to energy inefficiency
● It causes waste of CAPEX and OPEX
Old model: Build it now because it is too painful - slow - risky -
burdensome - costly to adapt later
New model: Modular design for scalability
● Capacity can also be scaled to meet changes in power density
and redundancy
Designing with standardized modular plants is inherently
more scalable than traditional methods
28
Schneider Electric

29. Reason #5: Control & management system
costs
● Controls and management system cost in traditional data center is
around $.50 -$1.50 per watt (under 10% of system cost)
● To actually correctly engineer such unique systems for a traditional
data center should cost about $5 per watt (nearly equal to expected
system cost) if we
● Optimized for energy savings
● Did full testing under all operating and fault conditions
● Documented the system fully
● Embedded effective diagnostics
● Did appropriate fault-tree and event-tree analysis
● Designed to accommodate expected changes
The costs of optimized control and management
software must be spread across many data centers;
Making standardized modular plants allows this
29
Schneider Electric

30. Reason #6: Lower installed and operating costs
Extra installed costs Installed cost savings
● Container / skid / package costs ● One-time engineering
● More smaller devices replace fewer ● Defer costs of capacity not yet
larger devices required
● Programming & configuration
● Rigging
● Documentation
● Shipping / installing damage
● Factory vs field labor
Extra operating costs ● Less field testing
● None identified
Operating cost savings
● Reduced expertise requirements
● Energy costs
● No maintenance costs on capacity
These savings are not speculative. yet required
not
they are common sense
30
Schneider Electric

31. Reason #7: Operation and Maintenance
● Reduced risk of human error
● Easier to standardize processes and procedures
● Repeatability – reduced field delays
● More flexibility to adapt to changing business needs
Old model: One-off designs create unique requirements 
higher risk
New model: Continuous improvement across business /
industry
● Makes concurrent maintainability easy
This represents the majority of value as most risk of
downtime is associated with operating and maintaining
the data center.
