I have two questions, (or maybe one question for two distinct circumstances) both about IAQ system design and requirements.

First, has anyone here had any experience setting up a HAVC systems including IAQ elements for pot growing facilities in the "legal" states? I'm in Missouri and a guy I know who used to manage a local parts house moved to Colorado about 18 months ago. he has said there is big money in setting up these places. I was just wondering about the specs for those rooms. I would love to be ahead of the curve when it comes my way.

Second, I may have the opportunity to bid on a large amount of geothermal work for both the heating and cooling of large animal storage rooms. (barns) The idea is to create a better environment for growing the feed animals. Current technology in the summer is giant fans on one end of the building and giant hole on the other end. so, you have hot animals losing weight and rampant disease. Closing up the building and providing cooling through geothermal may be financially feasible but I don't know about the humidity and air filtration problems.

so, where is a good place to start learning about high capacity and specialized IAQ systems?
