6 FAQs about [Solar Reflective Wall]
What is a cool exterior wall?
Cool exterior walls, like cool roofs, are materials that strongly reflect sunlight (solar energy) and cool themselves by efficiently emitting any heat that was absorbed. The exterior wall surface stays cooler and reduces the amount of heat conducted into the building.
Can retroreflective cool walls improve with diffusely reflecting cool walls?
Retroreflective cool walls could improve upon diffusely reflecting cool walls by reflecting incoming beam radiation to the solar disc (if the retroreflection is three dimensional and ideal) or at least upwards (if the retroreflection is two dimensional and/or imperfect).
Can solar retroreflectors be used on exterior walls?
Today, corner and spherical retroreflectors are widely used for traffic safety, remote sensing, and optical communication. Here we explore the application of solar retroreflectors to exterior walls. For example, consider an isolated building with 0.60 wall albedo and 0.20 ground albedo, each surface a Lambertian reflector.
Are safety films suitable for retroreflective cool walls?
The modest retroreflection observed at large incidence angles (50–70°) suggests that safety films may not be ideal materials for retroreflective cool walls, but quantitative tests, such as measurement of bi-directional solar reflectivities, may be warranted. Fig. 12.
Can a wall retroreflector cool a building?
Wall retroreflectors could cool buildings and reflect sunlight out of the city. Technologies relying on total internal reflection may be not suited for walls. Materials can be screened with a simple laser-and-paper goniometer. Two-surface retroreflectors incorporating orthogonal mirrors show promise.
What is the difference between solar reflectance and thermal emissivity?
Solar Reflectance is the fraction of solar energy that is reflected by the roof or wall’s surface. Thermal Emittance is a measurement of how well a material can shed the heat it absorbs. Materials with a low emissivity will tend to retain heat. Imagine a metal wrench left in the sun; it will be hot to the touch due to its low emissivity.
