How To Share Your Way To Save

From Wiki

I wanted to share some tips for data center energy efficiencies that represent relatively simple and inexpensive changes that can have a sizable impact. Below are five strategies to increase data center energy cooling efficiency and reduce energy costs.

1. Proper sealing of the data center environment A vapor seal plays a critical role in controlling relative humidity, reducing unnecessary humidification and dehumidification. Your building should already have one but mixed-use buildings are often weak in this area.

2. Optimizing air flow Rack arrangement, computer room air conditioner placement and cable management all impact the amount of energy expended to move air within the critical facility. Remember your blanking plates. Plug those holes in the racks and floors where hot exhaust air can easily mix with cold supply air.

3. Using economizers where appropriate Economizers allow outside air to be used to support data center cooling during colder months, creating opportunities for significant energy savings.

4. Increasing cooling system efficiency New technologies, such as variable capacity systems and improved controls, are driving increased efficiency of room air conditioning systems. Retro-fits generally have paybacks measured in months.

5. Bringing cooling closer to the source of heat Supplemental cooling systems bring cooling closer to the source of heat, reducing the amount of energy required for air movement.

Together, these methods can reduce cooling system energy costs by 30 to 45 percent and generate significant, recurring savings. Coupled with emerging technologies such as higher-efficiency processors and new chip-based cooling technologies, these measures can keep energy costs in line as server densities and the price of energy continue to rise.

Another source to check out is an independent group The Green Grid[2], a global consortium dedicated to advancing energy efficiency in data centers and business computing ecosystems.
