Blade servers consume about 10 percent less power than equivalent rack mount servers because multiple servers share common power supplies, cooling fans and other components. More importantly, blades facilitate the move to a high-density data center architecture, which can significantly reduce energy consumption (by around 20%). The cooling practices for computers such as the hot-aisle/cold-aisle rack arrangement; sealing gaps in floors, using blanking panels in open spaces in racks, and avoiding mixing of hot and cold air, helps in cutting down power consumption. Computational fluid dynamics (CFD) can be used to identify inefficiencies and optimize data center airflow. Newer technologies, such as digital scroll compressors and variable frequency drive in computer room air conditioners (CRACs), allow high efficiencies to be maintained at partial loads. In the chilled water-based air conditioning system used in this analysis, the use of variable frequency drives provides an incremental saving of four percent in data center power consumption.

Rack densities are rarely uniform across a facility and this can create cooling inefficiencies if monitoring and optimization are not implemented. Cooling control systems can monitor conditions across the data center and coordinate the activities of multiple units to prevent conflicts and increase teamwork.

There are many automatic devices can help in saving energy used in Installing infrared sensors, sensors, automatic timers, solar cells and such wherever applicable to switch on/off light-circuits is a good idea. Movement detectors should ideally be installed in washrooms and common areas. Also, using a time based lighting system, which can be programmed to suit office timing and requirement patterns, helps cut down on the electricity bill to quite an extent. One could also try installing mirror optic lighting systems, which will double the lighting while cutting down the number of light bulbs by half.

The best source of light, daylight is the oft-ignored resource for lighting solution. Installing full length glass windows helps in allowing natural light inside which also helps in slowing down the meter. One could begin by making sure that all refrigeration units are kept away from direct sunlight or other heat emitting appliances. A lot of energy is wasted if the cooling escapes through the ceiling. Place a lit flashlight inside when it is dark outside to see if the light escapes; if it does, it is time for you to change the sealing. While it is important to not let the cooling inside escape, it is equally important to let the heat around refrigerators escape. Allow ample space for continuous airflow around it. Also keep in mind to not stuff the refrigerator so much that the air circulation inside is stifled

It is advisable for businesses to run a power audit that investigates all processes followed in the company and the equipment used. Try to use as much natural light as possible during the day time. Install compact fluorescents or high-efficiency bulbs install movement-sensors, time-based lighting systems. It is better to not opt for central air conditioning and go with split air conditioning. Set up an IT policy to switch off monitors of idling PCs. Unplug electronic equipment when not in use like phones chargers, copiers, printers, etc.
