Dear ASHRAE: Congratulations on the new headquarters! We’re happy we could help. The Dynamic V8 Air Cleaning System is used throughout the LEED renovation of ASHRAE headquarters. The V8 is newest advance from Dynamic and is the new Green Standard for air cleaning. Dynamic The V8: provides the ultimate air quality — MERV 13-16 performance uses 2/3 less energy than passive ﬁlters up to 10 times the loading means a fraction of the maintenance and a fraction of the waste The V8 does more with less. V8 available and users must be educated about the impact power supply size has on energy consumption. Designing fo r high density. A perception persists that high-density environments are more expensive than simply spreading the load over a larger space. High-density environments using blade and virtualized servers are significantly more economical on capital expenditures (reduce floor space requirement, plant capacities) and on the operating costs (energy consumption). Depending on the details of the application, high density environments may be less likely to survive brief power outages. Mitigating this effect may necessitate adding cooling components to the UPS load. High-voltage distrib ution. 415V power distribution is used commonly in Europe, but UPS systems that easily support this architecture are not readily available in the United States. Manufacturers of critical power equipment should provide the 415V output as an option on UPS systems and can do more to educate their customers regarding high-voltage power distribution. Integrated measurement and control. Data that can be easily collected from IT systems and the racks that support them has yet to be effectively integrated with support systems controls. This level of integration would allow IT systems, applications and support systems to be more effectively managed based on actual conditions at the IT equipment level. Conclusion Data center managers and designers, IT equipment manufacturers, and infrastructure providers must all collaborate to reduce data center energy consumption. In the immediacy, there are a number of actions that data center managers can take today to significantly drive down energy consumption while freeing physical space and power and cooling capacity to support growth. By following the strategies outlined in this vendor-neutral roadmap for reducing data center energy consumption, data center managers can potentially realize a 50% or greater reduction in data center energy consumption without compromising performance or availability. All of the technologies used in this Energy Logic approach are available today and many can be phased into the data center as part of regular technology upgrades/refreshes, minimizing capital expenditures.
