1 Data Center Energy Efficient Cooling Control Demonstration PIR (formerly Federspiel Controls)

2 Background 2009 PIER sponsored project resulted in the installation of intelligent supervisory control and wireless mesh network sensing systems to reduce cooling energy at the California Franchise Tax Board s Sacramento data center. Elements of the energy saving system: perforated floor tiles for the under floor air distribution system variable frequency drives (VFDs) for fans, wireless temperature and humidity sensors connected in a mesh network components are connected to intelligent control software and adapts to changing conditions to ensure data center reliability and minimize cooling energy consumption

3 Major Accomplishments from the 2009 Project Cutting costs in Data Centers (State Partnership for Energy Efficient Demonstrations) Data centers consume over 9 billion kwh/year Partners: California Franchise Tax Board, Federspiel Controls, Lawrence Berkeley National Labs Purpose: Install data automation software and hardware system that uses wireless sensors and web based software to control computer room air conditioning units. Results: Lowered total energy use by 21.3% Saved 475,000 kwh/yr Payback of 3.1 years Bottom line: $42,722 per year saved Technology Transfer: FTB plans to use this technology in other data centers. Federspiel Controls subsequently secured a federal grant to expand this technology to 12 other state owned data centers. 3

4 Background (Continued) In 2010, the U.S. Department of Energy and the California Energy Commission granted funds to Federspiel Controls to replicate the success of the 2009 project under varying conditions in eight State of California data centers. These grant awards would not have been possible without the success of the 2009 project. In May 2011, Federspiel Controls changed its name to Vigilent.

5 DOE Information and Communication Technology Portfolio Commenting on the 14 project U.S. Department of Energy portfolio of energy grants that includes this project, U.S. Secretary of Energy Steven Chu announced: By reducing energy use and energy costs for the information technology and telecommunications industries, this funding will help create jobs and ensure the sector remains competitive.

6 Project Uniqueness and Approach Tested technology at eight data centers of varying sizes from small localized data centers (< 1000 square feet) to medium and large data centers (up to 40,000 square feet). The sites and results are listed on the following slide. Tested data center reliability with variations in cooling unit types, equipment ages, and data center layouts. The American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) publishes acceptable temperature ranges for inlet air to data center equipment. This project produced energy savings by implementing an intelligent energy management system that measures, monitors and actively controls cooling units, providing just enough cooling to meet ASHRAE requirements.

Two companies directly benefited from this project and increased their workforce: Vigilent added four highly skilled positions that were full-time advanced technical or managerial positions, and one part-time position. UMAI, which manufactures Vigilent hardware, added six full-time employees to its staff as a result of Vigilent orders.
