Abstract
Laboratory ventilation is integrated. The HVAC room controller requests changes in the exhaust set point of one or more fume hoods. By allowing the fume hoods to respond to such HVAC requests, the fume hood exhaust may be turned down to a point below the highest level that could be needed. The request may be used to turn the fume hood exhaust back up, so greater energy savings may be possible in non-peak demand operation of the HVAC system.
