Energy use and savings potential for laboratory fume hoods
Typically relied upon as a primary source of ventilation in laboratory-type facilities, while also providing for safe conditions in areas in which experiments are being conducted, fume hoods are critical energy end-use devices. Fume hoods require large amounts of airflow,which drives the overall HVAC sizing and energy requirements of the buildings in which they are located. For standard six-foot hoods,per-hood energy costs range from $4,200 for moderate climates such as Seattle, USA to $8,200/year for extreme cooling climates such as Singapore. With an estimated 750,000 hoods in use in the U.S., the aggregate energy use and savings potential is significant. We estimate the annual operating cost of U.S. fume hoods at approximately $3.8billion, with a corresponding peak electrical demand of 5,000 megawatts.With emerging technologies, per-hood savings of 50-75 percent can be safely and cost-effectively achieved.
