Project Summary

This energy efficiency study determined the demand reduction and energy savings of 12 vertical sash, variable air volume fume hoods. The assessment compared the volumetric air flow rates of fume hoods with and without automated sash positioning control systems (ASPCS). Twelve hoods were studied: 6 hoods with automated sash positioning control systems and six without this sash control system at a large biotechnology company with 651 fume hoods in operation.
