We describe the potential of using hygroscopic materials that release moisture and latent heat in order to reduce the temperature of building envelopes and, there upon, conduction cooling loads. It is analysed 3 different weathers and a classic Brazilian wall with different values of paint permeance on both external and internal surfaces. The results are presented in terms of temperature, moisture content profiles and heat fluxes, showing how to save energy from the natural movement of moisture.
