Base Building Coordination

• This is the Team already performing the Base Build.• Coordination has already been on-going.

– Example: Power needs for Data Center being coordinated now to eliminate rework.

• No one understands the permitting and inspection process like we do.

LEAN

• Manufacturing LEAN Six Sigma driven to reduce all waste– Materials, energy, time, manpower– Process optimization, automation, and control– Quality systems

• Construction LEAN – Last Planner – Collaboration– Just in Time Delivery

Sustainability

• Emerson’s environmental stewardship efforts include: – Developing technologies that help address environmental challenges– Applying cost-effective and energy-efficient manufacturing processes

• Innovative Technologies for a Greener World– Enabling efficient use of energy– Supporting cleaner forms of energy production– Providing technologies that monitor and limit emissions

• Energy Saving Operating Initiatives– Replacing shop lighting with fluorescent, add motion sensors, turn off sodium lights in Weld Shop– Replacing Bondrite cleaner with NT-1 in Powder Paint– Using heat recovery from compressor for powder paint area make up air– Adding VSD to 70HP compressor, replacing standard electric motors with premium efficiency

• Environmental Operating Compliance– Annually assess the environmental compliance of each Emerson facility– Adhere to industry standards and initiatives - WEEE, RoHS, EPEAT, CSCIhttp://www.emerson.com/en-US/about/corporate-citizenship/csr-sustainability/Pages/default.aspx

Sustainability

• DPR builds ALL projects as if they were LEED projects. It’s simply the right thing to do.

• Unmatched LEED Data Center Experience• Maximum construction recycling• APS Energy Efficiency Incentives- currently

coordinating with APS.• 28 Local LEED AP, over 350 nationally• ASU Poly Local LEED Gold Certified (DPR/ESD)

Cooling

Central Plant

• Variable Primary System design• N+1 Redundancy• Two cooling loops (55°F Loop & 78°F Loop)• Initially have cooling capacity of 2MW of IT

load in each loop• Could be increased to total of 5MW of IT

load

Mechanical Flow Diagram

Cooling System 55°F Loop

• Utilizes variable speed chiller• Chiller at 0.440 kW/Ton at peak cooling load (Max.

summer temperature)– COP of Central Plant = 6.25

• Chiller at 0.225 kW/Ton at peak cooling load (Mild outdoor condition)– COP of Central Plant = 10.2

• 34% of time on free cooling mode (Chiller will be off)– COP of Central Plant = 28.8

Cooling System 78°F Loop

• Utilizes Cooling Tower/Heat Exchanger• 97% of time can provide 78°F water or lower

– COP of Central Plant = 28.8• 3% of time need assistance from 55°F loop

– COP of Central Plant = 21.3

Design Highlights

• Liebert® XD™ platform (Liebert® XDS™ server cooling rack) enables direct liquid cooling

• Total site can support above 4 MW of IT load with high density cooling– First floor utilizes Liebert® XDR™ rack door cooling modules

and Liebert XDS, enabling 4 MW of IT load– Additional containers on the roof can push IT Load towards

CFD Analysis of Emerson SmartMod- Liebert XDR

Water-Based Rear Cooling Doors

• We did not quote a water based solution for a variety of reasons.– Water door solution limits future

growth to 30KW per rack, maximum.

– Minimal energy savings by not having a secondary loop.

– Leaks with no secondary loop can be catastrophic.

• Refrigerant-based infrastructure provides a migration path to 40KW and beyond.

Design Philosophy - Transformer-Based UPS

• Emerson Network power offers both transformer-free and transformer-based UPS

– We feel there are appropriate applications for both– Our UPS systems for the SMB space are transformer-free– Our UPS systems for the enterprise space are transformer-based

• We made the decision to go transformer-based on our enterprise UPS for availability– Galvanic isolation at the input and output for DC fault isolation– Output isolation safely protects the critical load and makes for robust fault

management– Transformer-based UPS rectifiers use ultra-reliable and efficient SCRs and

simple inverters in open (or closed) delta configurations• A comparable transformer-free UPS uses high voltage DC and has a lot more

semiconductors due to the need for an additional buck-boost charger in the rectifier and neutral management in the inverter

• The semiconductors in a transformer-free design see more of their operating limit than a transformer-based design
