Insulating the heat-bridges that are causing the condensation will reduce the heat lost, hence reduce the cost of maintaining a constant temperature.
Heat is transferred at a rate proportional to the difference in temperature, hence maintaining a lower temperature is cheaper regardless of insulation (assuming you don't change the insulation).
