As part of a laboratory building remodel, the design engineers are proposing an "Aircuity" system to monitor air quality and adjust ventilation rates accordingly as part of an energy savings method. Do you have experience with this or a similar system and would be willing to share that experience with me?

Energy savings and absolute safety might be incompatible when it comes to laboratory ventilation. Questions that come to my mind relate to the reliability of the system, the degree of specialty knowledge needed to maintain such a system, and changing demands on chemical uses. What if the type of chemicals change in a lab? Does that require a new sensor? Who makes decisions on the quality of the readings? What happens if the system fails? What if quality slowly degrades vs. a sudden failure? Will people monitoring the system be able to detect it?

Thanks in advance for your knowledge,
