Lab / Vivarium Demand Control Ventilation

OptiNet Application

Maintaining proper ventilation in laboratories, research facilities, and vivariums requires a lot of energy. The advantage of AirGenuity’s system is two-fold. Firstly, the continuous monitoring and control provides invaluable insight into the actual air quality. Secondly, safety standards are met and energy use is lowered by continually optimizing ventilation rates.

Air Exchange Rates:  How much is enough?

Determining proper air change rates in laboratories is often a debated topic amongst facility owners, operators, and safety personnel. The use of 100% outside air makes each air exchange costly, but ensuring a clean working environment for researchers and occupants is always the primary consideration. The reality is that setting a single air change rate to balance safety and energy consumption will not achieve either objective.

Knowledge saves energy & costs

Replacing clean indoor air with clean outdoor air is a waste of energy and money. That’s why AirGenuity’s lab DCV solution automatically adjusts ventilation rates based on the data obtained by continuously monitoring critical environments. The reality is that setting a single air change rate to balance safety and energy consumption will not achieve either objective.

Safety benefits

With the lab environment continually being monitored, safety personnel have a window to what is happening in their lab 24/7. Manual intervention is no longer necessary when an issue occurs. That’s because ventilation rates adjuste automatically. By reviewing IEQ quality, safety personnel can identify, evaluate, and determine frequency of incidents. This gives them valuable insight into improving lab protocols.

Energy benefits

Energy savings can be as much as 50% by reducing air exchange rats to 4 ACH in occupied mode, and  2 ACH during unoccupied mode. There is a tremendous potential for energy and savings in critical environments.
