Condensation effect occured when are combined three factors heigh humidity ,cold surface of glass or wall and too heigh/or too low room temperature.
For keeping low humidity level we should use tricle vents , often openning window or dehumidification.
Importent is using Low E glass U=1,1, insted ordinary glazing U=2,8W/Km2 .Also timber or uPVC windows have "warmer" frame then aluminium.Sometimes people have not thermally broken aluminium door/window, it will always casue condesation.
Another cause for "cold" wall is bad insulation (or no insulation ) between wall and windows frame.
