Nitrogen tanks hooked up to a water storage tank is already an option in 13D (See TALCO's FFX system.) While I expect pressures (operating) to be higher for mist systems, I can see the benefit of very small high pressure tubing in some type of wire mold in an existing structure. The $100,000.00 savings is somebody blowing smoke up you know where, or they inhaled more than once. The largest 13D system we ever did was 44,000 SF and it was about a $50K job. So unless the average home is now 250,000 SF I don't see any way even at half the cost to save 100K. I love the statement 13R for single family and duplex homes in the copy of Gannon's study. Obviously Marriott is more in keeping with 13R, in their retirement and lodging settings. Personally I think there is more to be studied, and perhaps something that looks more like a "Vortex" system will come of it someday. Right now unless someone is volunteering their community to be a Guinea Pig for this mist system, I don't see its application as a option in 13D or R very soon. Of course you could always do it a "Equivalent" engineered design.
