Embodiments of the present disclosure are directed to coating compositions, coated articles, and methods in which the coated article is adapted to exhibit a particular permeance profile, such as, for example, a variable water vapor perm rating of about 1 perm or less at 25% average RH and about 15 perms or more at 95% average relative humidity, as tested by ASTM E96 at 21&#xb0; C.

Coating compositions for building materials and coated building material substrates

A roof system is secured to a roof deck on a building. The roof system has a thermal energy absorbing product including a desiccant located between the roof deck and a roof barrier. The desiccant reversibly absorbs moisture, and in response thereto, heat is released and absorbed by the desiccant to effect a thermal management of the roof system.

A method of reducing the amount of cooling energy required to heat and cool a building is provided. The method includes disposing a porous insulating material in the exterior walls and substantially covering the ceiling in the attic space of the building to a substantial depth. The porous insulating material includes a desiccant. The method further includes permitting the desiccant&#x2014;bearing porous insulating material to adsorb water moisture from the attic space and then permitting the adsorbed water moisture to desorb from the desiccant&#x2014;bearing porous insulating material into the enclosed room of the building, resulting in a reduction in the amount of energy required to heat and cool the building.
