A coated nonwoven mat includes a nonwoven base layer formed from a plurality of fibers held together by a binder. The nonwoven base layer includes a first surface and a second surface. The coated nonwoven mat includes a coating layer adhered to the first surface. The coating layer includes a coating composition having less than 5% of organic material, based on the weight of the coating composition.

A system passively cools, regulates humidity and/or rectifies diffusive transport of water vapor in an interior area within a structure. The system includes a membrane assembly covering a portion of the structure, wherein the membrane has an interior side facing the interior area and an exterior side. The membrane assembly defines a plurality of pores. When cooling, a supply of fluid is provided to the membrane assembly so that capillary action of the pores redistributes the fluid to create evaporation and, in turn, the desired heat flow. The membrane assembly can include an architectural membrane coated with a porous matrix coating to form the pores. A pump can provide the fluid to the interior side of the membrane assembly. Preferably, the architectural membrane is woven PTFE-coated fiberglass and the porous matrix coating is titanium dioxide, zeolites and/or silica gel.

A precast building material contains a substrate, a peripheral frame, a metal reinforcement unit, and a concrete layer. The substrate is in a parallelogram shape. The peripheral frame is mounted around the substrate so that an accommodation chamber is defined between the peripheral frame and the substrate. The peripheral frame includes multiple first connection rails having at least one first slot, multiple second connection rails having at least one second slot, multiple first engagement portions, and multiple second engagement portions. The respective first connection rail has multiple first locking orifices, and the respective second connection rail has multiple second locking orifices. The metal reinforcement unit is fixed in the accommodation chamber and includes multiple rebars. The concrete layer paving the accommodation chamber, and the concrete layer is connected with the peripheral frame and the metal reinforcement unit and is removable from the substrate.

Gypsum board having a core, said core having at least one side covered with a non-woven fabric; characterized in that the inner side of the non-woven fabric, which is in contact with the core of the gypsum board, has a surface roughness Ra of from 25 to 60 micrometers, preferably from 25 to 50 micrometers, advantageously from 25 to 40 micrometers.
