ground reflectance factor of wooden decking

List of reflectance / albedo of common materials - Corona RendererList of reflectance / albedo of common materials. ... batten (fresh wood) - 0.35-0.42 [D-S] face skin - 0.25-0.35 [M] white dry ... At most, it shows there is no pure white or black diffuse, which might be obvious, but even shops like DesignConnected use crazy numbers like pure 255 white for white materials,..then they need to lower 90degree reflectance to some mid-number to compensate for glaring extremities and you end up with odd, washed up material. Another thing ...

Pool Deck Surface Material Comparison - The Concrete NetworkHomeowners weigh many factors when choosing a material to pave their pool decks, including the cost, slip resistance, upkeep, durability, and how well it complements the surroundings. ... Heat Reflectivity. Compared to darker-colored brick and tile pool decks, which can become extremely hot to the touch after baking in the sun, concrete reflects solar radiation and is more comfortable on bare feet. There are also decorative toppings for concrete that can be used to significantly lower ...

The reflectance of the ground - PV LighthouseOn the previous page, the albedo was defined as the broadband average of the reflectance. The albedo serves as an approximation to calculate backscattering. Because solar cells are usually mounted at a tilt angle s from the ground, they face not only the sky, but partly also the ground, expressed by the ground view factor: Eq ground view factor. Hence, a part of the sunlight that enters the cell does not come directly from the sky, but is first reflected at the ground in the near or far ...

Safest Decks to Have Surrounding Your Swimming Pool - Leisure ...17 May 2017 ... In addition to providing innovative pools for your home, we also prioritize safety. Here are the safest decks to have surrounding your swimming pool.

Physical factors in cataractogenesis: ambient ultraviolet ... - IOVSThus the greatest ocular exposures result from ground re- flections from snow, followed by sand, concrete pave- ments, wooden walkways, boat decks, and water, and not from the horizon sky or from green grass or foliage. In fact, the reflected levels of UVR from light sand should be sufficient to cause a threshold photokeratitis within exposure periods of 6-8 hr centered around midday. Table 2 summarizes the measured reflectance values. The presence of a tree-line or hill would also.

Average Ground Reflectance InfoAverage ground reflectance Info. Average ground reflectance (also known as albedo) is defined as the average fraction of incident radiation reflected by the ground. The respective values should be in a percentage form (e.g. 0% stands for total absorption and 100% for total reflection). The following table reports estimates of average reflectance values respecting different materials. If you are not sure about the appropriate value just leave the default one.
