Hello Rich Walden,

Run the evap-cooled air through a double clad exterior-- thus it eliminates humidity inside the building. This link was written by a New York architect for NYC:

I am not an architect/engineer, but it seems like sound engineering to save lots of energy.

Well I must say that the link certainly isn't you fathers squeaky window swamp cooler. While those buildings referenced seem much more efficient, as well they should be, being specificially designed, are they a concept or a practical solution? I can't say which, but there is some excellent ideas and some which seem at first glance to be highly impractical. For the last 5 years before my retirement, I is was involved in the production of advanced building materials. It was not difficult to get people to say it was a great idea, but try to get them to sign on the dotted line to use it was another thing. I think the concepts used in those buildings have promise, but the devil is in the details
