Summary:Sharp discusses the environmental and energy savings impact of safely reducing and controlling air change rates in labs and vivariums. Air changes can be safely reduced in labs and vivariums by dynamically varying air change rates with a demand-based concept that uses air quality level or "air cleanliness" of the lab or animal room to control its air changes or minimum dilution ventilation airflow. Determining the "right" ventilation rate level for clearing a room of fugitive emissions or spills, no single correct value exists for all situations. The airflow amount required to rapidly clear the room after an event or release of chemical vapors varies significantly based on the amount of the release, the chemical's evaporation rate, and the level of hazard of the chemical.
