摘要
Methods, systems, and apparatus are described which can safely reduce a laboratory fume hood's minimum airflow and energy consumption when it is determined that the fume hood is not in active use, based on a condition monitoring approach. The condition monitoring approach may incorporate a combination of setback criteria to reliably determine if the fume hood is or is not in use. When a determination has been made that a fume hood is not in use, energy reduction is achieved via automatic methods of hood minimum airflow setback. Fume hood minimum flow reductions are automatically disabled when it is determined that the hood is in active use.
