The albedo of several types of roofs (lower values means higher temperatures). Reflective surfaces, or ground-based albedo modification (GBAM), is a solar radiation management method of enhancing Earth's albedo (the ability to reflect the visible, infrared, and ultraviolet wavelengths of the Sun, reducing heat transfer to the surface).
Despite the use of aluminum in generic mirrors, aluminum is not always used as the reflective layer for a solar mirror. The use of silver as the reflective layer is claimed to lead to higher efficiency levels, because it is the most reflective metal. This is because of aluminum's reflection factor in the UV region of the spectrum.
Aluminium (or aluminum in North American English) is a chemical element; it has symbol Al and atomic number 13. Aluminium has a density lower than that of other common metals, about one-third that of steel. It has a great affinity towards oxygen, forming a protective layer of oxide on the surface when exposed to air.
The useful daylight illuminance calculation is based on three factors—the percentage of time a point is below, between, or above an illuminance value. The range for these factors is typically 100–2,000 lux. Useful daylight illuminance is similar to daylight autonomy but has the added benefit of addressing glare and thermal discomfort. [44]
A solar map, in general, is a map of a city, state, country, or any piece of land that illustrates information about how much a certain piece of land, building, or home experiences a certain amount of sunlight. Though solar maps are illustrated in many forms, a solar map essentially records where and to what extent a certain location ...
