Whatever you do…. Do not put the air intake near the hood exhaust. Nor downwind from it. Nor near the shipping dock.
Years passed under the presumption we had shared ventilation systems, until one day we had a long chat with our HVAC repair guy. Turns out the labs had dedicated ventilation
systems… except they put the intake and exhaust vents practically next to each other, and right above where trucks would idle.
The trucks idling was an easy fix. The other… not so much.
Which goes back to Peter’s comment... get yourself a good ventilation engineer.
Thank you,

It sounds like you are adding chemistry labs and their ventilation to a building that already contains biology labs and their ventilation. Biology labs may not
have been given quite as robust a ventilation system as chemistry labs would need. Adding on may require substantial upgrades to the exhaust equipment, reassessment of the system’s exhaust points and stack height, and will certainly require careful design
by a ventilation engineer who has knowledge of and prior experience with laboratory ventilation. Do not leave it to the architect, or to just any design engineer.
The only issue I can see with stacking both floors on the same system is the need to ensure against backflow where effluent air from one department might be transported
into the other department..

Hi all,
Does anyone know if there are any safety issues/concerns that need to be addressed when sharing a ventilation system of the labs on the first and second floor? We are in the designing
stage of building chemistry labs on the first floor and sharing the ventilation system with the biology labs on the second floor.
Any input is greatly appreciated. Thank you,
Vera Alino
