Thanks. Yes, I already had an output duct with two duct-fans in tandem, which removed air from the lab, directly to the outside. In a colder area such as mine, this involved a lot of heat loss, which was expensive due to my electric baseboard heaters. I think a simple opening to the outside would work about the same, which would allow the incoming air to exit the lab easily. How air-tight the lab is would make a difference. If air can escape fairly easily, and I assume it can in most labs, then it might not be necessary to add an output duct.
