Higher extraction volumes also make heating and cooling bills go up.

It's one of those ideas that works fine when it's just a rare thing, but if 100% of households had one I guarantee we'd see headlines like "Wasteful Exhaust Vents Burn As Much Energy As Cleveland" etc etc.

I for one welcome our fume hood inspired overlords. The nice thing about fume hoods is that they're optimized for maximum extraction efficiency for a minimum extraction volume.

Everyone notices the side walls, but an overlooked secret of fume hoods is that they extract air backwards toward the back wall, not just upward.

Any air extraction pulls conditioned air out of the house - kitchen hoods, dryers, bath fans, etc. Only kitchen hoods exhaust a significant amount of air - the solution is a makeup air system.
