Data Center Retrofit: Heat Containment and Airflow Management PDF

An existing raised floor data center with 5,000 kW of information and communication technology equipment load capacity was expanded in 2004 to accommodate an additional 3,000 kW of high-density load. The additional space needed to serve higher density racks of up to 16 kW per rack with an average density of 8 kW per rack. This project demonstrated the applicability and cost effectiveness of variable airflow in data centers. CO₂ produced was decreased by 2,000 tons/yr (1,814 Mg/yr) with a direct energy savings of 16,210,930 kWh/yr. This is an ASHRAE Technology Award.
