I agree with WatJohn - the 75% RH is clearly problematic and as Laren  
mentioned, the single-glazed windows are puzzling given the details for  
the rest of the space.

Since it is mentioned that the space is unheated, I'm going to assume that  
it's not used as living space.

If that ass-ump-tion is accurate then I'd be inclined to install R-20 (or  
better)  insulated shutters for those windows and turn on an  
energy-efficient light bulb on those occasions when a person makes brief  
visits to the space.

One could of course, cut small (say 6" x 12" or smaller ?) holes through  
the insulating shutter and make quadruple or sextuple-glazed inserts to  
fill those holes to allow some daylighting.
