industrial greenhouses make noise? I live near Forest Hill, LA, which is where tons of nurseries set up, dozens and dozens. they all have greenhouses. No noise. I bet their electrical connections don't raise prices of local residents, either.
So is it the water? I don't know where i sit on the water argument. Equinix near LAX had chillers, i guess, but really it's just massive HVAC. chillers don't work everywhere (my understanding). I don't remember plumes of humidity coming off the facility, either. I also don't remember being able to hear it from outside the building, or even in the foyer before you went through the mancatchers.
In my experience this really depends on the scale you're operating at. What works for a side project falls apart at production scale.
