moisture on wood floor
i have a project where the homeowner wants to put a bedroom over top of half of his heated indoor pool.  any suggestions on what can be done to reduce the amount of moisture on the bedroom floor due to the humidity?  my initial thought was a vapor barrier and green board on the ceiling below, but maybe there is a better solution.
some things to consider in rooms with high moisture content, particularly indoor pools that not only produce high levels of humidity, but with the water vapor, also contain corrosives (chlorine).
1. water vapor will permeate through common building materials and condensate against non-permeable materials (plastic vapor barrier). once water vapor has condensated in sufficient quantities, water will drip or run off.
2. structures such as enclosed ceilings above high humidity prone areas will become collectors for water. this will encourage decay and fungus damage if framing   
i agree with the above answer.
the suggestion i make may be overkill [depending on the size of project and/or budget constraints].  suggest to owner/architect to consult with a good mechanical engineer to design hvac system.  the design of the structure should take into account the environment.  the structure does not eliminate the effects of the environment on the structure.
regardless of what material you put on the ceiling/floor, if the ventalation is in adequate, you will have problems.  have the owner hire a mech eng w/ experience in indoor pools.
