Abstract
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—bearing porous insulating material to adsorb water moisture from the attic space and then permitting the adsorbed water moisture to desorb from the desiccant—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.
Claims29
A method of reducing the amount of cooling energy required to cool a building, said building having an enclosed room partially defined by an outer wall, a horizontal upper wall plate, and an attic space disposed above said upper wall plate, said attic space defined by a ceiling of said room and a roof of said building;
- said method comprising:
- a) disposing a porous insulating material substantially covering the ceiling in said attic space to a substantial depth, said porous insulating material including at least 5 vol-% desiccant;
- b) permitting said desiccant-bearing porous insulating material to adsorb water moisture from said attic space;
- and
- c) permitting said adsorbed water moisture to desorb from said desiccant-bearing porous insulating material into said enclosed room, whereby the temperature of said desiccant-bearing porous insulating material is reduced resulting in a reduction in the amount of cooling energy required to cool said building.
A method of reducing the amount of cooling energy required to cool a building, the building having an enclosed room partially defined by a wall, a horizontal upper wall plate, and an attic space disposed above the upper wall plate, the attic space defined by a ceiling of the room and a roof of the building, the wall comprising an inner panel and an outer panel with a wall space therebetween, the method comprising:
- a) disposing a first layer and a second layer of porous insulating material so as to substantially cover at least one of the group consisting of the ceiling in the attic space and the inner panel in the wall space with a separate layer comprising a desiccant material disposed in between the first and second layers of porous insulating material;
- b) permitting the layer comprising the desiccant material to adsorb water moisture from the attic space or wall space;
- and
- c) permitting the adsorbed water moisture to desorb from the layer comprising the desiccant material into the enclosed room, resulting in a reduction in the amount of cooling energy required to cool the building.
A method of reducing the amount of energy required to heat and cool a building, said building having an enclosed room partially defined by an outer wall, a horizontal upper wall plate, and an attic space disposed above said upper wall plate, said attic space defined by a ceiling of said room and a roof of said building;
- said method comprising:
- a) disposing a porous insulating material in the inner panel in the wall space with a desiccant dispersed throughout the porous insulation;
- b) permitting said desiccant-bearing porous insulating material to adsorb water moisture from said wall space;
- and
- c) permitting said adsorbed water moisture to desorb from said desiccant-bearing porous insulating material into said enclosed room, resulting in a reduction in the amount of energy required to heat and cool said building.
