Abstract:
1. A building incorporating a surface subject to a thermal gradient emitting from a building interior, to which is applied a thermal insulating assembly, wherein the thermal insulating assembly comprises: thermal insulation comprising first and second layers of insulation, one of the first and second layers of insulation being positioned adjacent to the surface of the building; and an electrical heating element provided with means for connection to a source of electrical power and positioned within the thermal insulation between the first and second layers so as to extend substantially parallel to the surface; said building additionally including first and second thermostatic controllers, said first thermostatic controller being operatively connected to determine the temperature of said electrical heating element and said second thermostatic controller being operatively connected to determine the temperature of the building interior, said first and second thermostatic controllers being programmed to cause said electrical heating element to increase in temperature so as to equalize with, and not exceed, the temperature of the interior of the building and thereby to establish and maintain a neutral temperature gradient between the building interior and said electrical heating element, said neutral temperature gradient preventing heat outflow from the building interior through the thermal insulating assembly, preventing heat flow from said electrical heating element to the building interior, through the inner of said first and second layers of insulation, relative to the building interior, solely through the outer of said first and second layers of said insulation, relative to the building interior, to the exterior atmosphere.
