An example of this would be an exterior wall of a building to which an "insulative" or "insulating" paint has been applied. Solar induced heat (direct sunlight) is reflected from the surface as well as heat (winter months) that is migrating through the wall outward toward the colder outside air.
LRV on Paint Swatch. In architecture, light reflectance value (LRV), is a measure of visible and usable light that is reflected from a surface when illuminated by a light source. [1] The measurement is most commonly used by design professionals, such as architectural color consultants, architects, environmental graphic designers and interior ...
The average daily summertime temperature of the black roof surface was 75 °C (167 °F), but once retrofitted with a white reflective surface, it measured 52 °C (126 °F). Without considering any tax benefits or other utility charges, annual energy expenditures were reduced by $7,200 or $0.07/square foot.(This figure is for energy charges as ...
Concrete walls with glass prisms running through them have also been made. With the advent of cheaper optical fibers and fiber-optic concrete walls, daylight (and shadow images) can then pass directly through a solid concrete wall, making it translucent; fiber optics will lead light around bends and over tens of meters.

Radiant barrier may be used as a vented skin around the exterior of a wall. [10] Furring strips are applied to the sheathing to create a vented air space between the radiant barrier and the siding, and vents are used at the top and bottom to allow convective heat to rise naturally to the attic.
For diffuse surfaces, such as matte white paint, reflectance is uniform; radiation is reflected in all angles equally or near-equally. Such surfaces are said to be Lambertian . Most practical objects exhibit a combination of diffuse and specular reflective properties.
