Airflow containment has moved from a trend to a best practice and has now become industry standard. Airflow Management represents the forefront of power-saving, cooling technology.

U.S. Department of Energy Best Practices Guide for Energy Efficient Data Center Design
The U.S. Department of Energy recommends the use of flexible barriers or other solid partitions to seal the space between the tops of the rack and the air return.
These types of airflow containment structures can greatly improve hot/cold aisle isolation while allowing flexibility in accessing, operating, and maintaining the computer
equipment. The Department of Energy also suggests that these changes should reduce fan energy requirements by 20% to 25%, and could result in a 20% energy savings on the
chiller side provided these components are equipped with variable speed drives.

U.S. Department of Energy Case Study at Lawrence Berkley National Laboratory
In a case study performed at the Lawerence Berkley National Laboratory, The Department of Energy found that by installing airflow solutions such as sealing leaks in the floor,
adding blanking-plates and installing barriers for hot/cold aisle separation a data center can experience a significant reduction in energy costs. Some of the results of the
findings included a 21% increase in cooling capacity, an 8% decreased in fan energy, the ability to increase CRAC unit set points by 3°F and an extended life of existing data

Google Case Study
Google operates many large data centers as well as other small to medium data centers around the world. This case study published by Google describes a retrofit of a smaller data center implementing airflow
containment best practices, and the return on investment which these strategies have produced. For this case study,
Google spent a total of $25,000 to optimize the data center airflow and returned a savings of $67,000 per year. This retrofit was done without any downtime and resulted in a return on investment of
under a year.
