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.
