2 The application of multiple available technologies resulting in improved energy optimization without significantly increasing capital investment. A case study in Data Center design and construction.

3 DESIGN AND CONSTRUCTION PARTNERS

4 Customer Requirements Build a world class data center Use newer proven technology but not bleeding edge LEED Gold certification minimum Low cost and fast delivery Meet Tier 4 requirements 2N redundancy for utilities 10,000 sq. ft. of white space divided into 4 data halls with 250 W/sq. ft. power density (25MW of computing power) Operate at a PUE of 1.5 or better

requirements 2N redundancy for utilities 10,000 sq. ft.

6 1. Identify areas of high energy consumption 2. Find efficient alternatives 3. Get customer approval to use alternatives 4. Incorporate the alternatives into a cohesive system

7 1. Identify areas of high energy consumption Moving massive amounts of cooled air Typically many air houses with 100HP motors cooling the entire rooms Chillers for producing chilled water Chilled water to cooling coils in the air houses Battery UPS systems Estimated 20,000 sq.ft. battery room to provide backup for up to 25MW for several minutes. Heating and cooling required to maintain 74 degree temperature to extend life of batteries. 220V distribution to equipment 13,800V primary to 480V secondary distribution transformed to 220V at PDU Lighting

ft. battery room to provide backup for up to 25MW for several minutes.

8 2. Find efficient alternatives Traditional Method New Method In Row Cooling 120⁰ + F ~ 74⁰ F

9 2. Find efficient alternatives New Method: Use smaller chillers to allow better load matching. Use free cooling (Michigan) Old Method: Use many large chillers to cool all of the equipment in the data center and equipment rooms.

Use free cooling (Michigan) Old Method: Use many large

10 2. Find efficient alternatives Traditional Method: A room full of batteries, connected to several UPS s Batteries generate heat and require 74⁰ ±4⁰ constant temperature Room also needs to be exhausted for gas.

Batteries generate heat and require 74⁰ ±4⁰ constant

11 2. Find efficient alternatives System One Line Overview New Method: Diesel rotary UPS electrically coupled highly efficient backup system.

12 2. Find efficient alternatives Traditional Method: Typical data center distribution in North America

13 2. Find efficient alternatives New Method: Typical IEC distribution

14 2. Find efficient alternatives Lighting Minimal levels of lighting in the data halls: Zoned and occupancy sensor controlled LED task lighting in the rack pods controlled by occupancy sensors The data halls normally have only egress level lighting if no one is in the room

15 3. Get customer approval to use alternatives Several reviews with very risk averse group of individuals but we were able to convince them to go in this direction The biggest concern was no 110V power in the data racks 4. Incorporate the alternatives into a cohesive system Chilled water distribution piping under floor in data halls Chilled water storage for backup allows us to drop mechanical loads and restart on generator (no UPS on mechanical systems) Bus duct distribution of 415V under raised floor VFD s on all motor loads

17 Effects of free cooling at Warren Data Center 28 Months operational 20,440 hours since start-up Three chillers 800 tons per chiller Chiller hours Chiller hours Total Chiller Hours = 8442 Chiller hours Total hours of free cooling = 11,998 Chilled water temp required at in row coolers is 54 degrees to maintain the 74 degree space temperature

Total Chiller Hours = 8442 Chiller 3 2789 hours Total hours of free cooling = 11,998
