- Install lighting controls such as occupancy sensors in data center halls, generator rooms, battery rooms, and other back of house areas. These controls can reduce total lighting energy consumption by 25% to 50% annually.
- Install energy efficient lighting that uses T-5 lamps with electronic blasts. This can reduce lighting energy consumption by 10% to 15% per year; and even greater results with newer LED lighting.
- Switch to variable speed motors for HVAC equipment such as computer and data processing room air conditioners, pumps, and cooling tower fans. A fan running at 80% speed will consume only 50% of a fan running at full speed.
- Raise the chilled water temperature set point to 48 degrees for chillers with variable frequency drives of 1% to 1.5%. For every one degree of chilled water supply temperature increase, there is a potential 3.5% chiller power savings.
- Adjust server rows to eliminate space between racks. Spaces between racks increase recirculation from the exhaust to the servers' intake, resulting in hot spots. The equipment will work more efficiently stacked side by side.
- Install new generation blade servers.
- Eliminate unused or static equipment
- Improve airflow efficiency
