Green Roof Ratio Of Total Reflected To Incident Electromagnetic Radiation

Green roofs cool as effectively as the brightest possible white roofs with an equivalent albedo of 0 7 0 85 compared with the typical 0 1 0 2 4 5 the hard ground reradiated the stored heat increasing the ambient air temperature.

Green roof ratio of total reflected to incident electromagnetic radiation.

Enhanced r efle ctivity of incident solar radiation. Some studies found out that green roofs could cool as efficient as the brightest possible white roofs with the same albedo of 0 7 0 85 in comparison with the typical 0 1 0 2 of a bitumen tar gravel roof gaffin 2005. By green roofs annual total building runoff can be. The ratio of total reflected to incident electromagnetic radiation is defined as albedo castleton 2010 1583.

Incident electrom agnetic r adiation is defined. 1 latent heat loss and 2 enhanced reflectivity of incident solar radiation. The ratio of electromagnetic radiation reflected from a surface relative to the amount of radiation incident on it. Hiring a professional electromagnetic radiation specialist or qualified personnel from the international electrical and electronics engineers to survey sample analyze and map the roof for the incidence and field strengths of radiation would be cost prohibitive and impractical for the typical small roofing contractor.

Albedo is defined as the ratio of total reflected to incident electromagnetic radiation. The crops we plant reflect more incoming light than does the dark green foliage of the rainforests causing an increase in the albedo and hence resulting in cooling. Gaffin 2005 17 suggested that green roofs cool as effectively as the brightest possible white roofs with an equivalent albedo of 0 7 0 85 compared with the typical 0 1 0 2 of a bitumen tar gravel roof 18. The inclination of the instrumentation was then adjusted to 17 the same as the roofs pitch.

Green roofs cool as effectively as the brightest possible white roofs with an equivalent albedo of 0 7 0 85 compared with the typical 0 1 0 2 4 5 the hard ground reradiated the stored heat increasing the ambient air temperature. The ratio of total reflected to incident electromagnetic radiation is defined as albedo. Green roofs cool as effectively as the brightest possible white roofs with an equivalent albedo of 0 7 0 85 compared with the typical 0 1 0 2 of a bitumen tar gravel roof. There are two factors which make green roofs cool.

According to this method the measurement uncertainty can be considered around 7. The ratio of total reflected to incident electromagnetic. The roof albedo is represented by the ratio of total reflected to incident electromagnetic radiation. The ratio of total reflected to.

The ratio of total reflected to incident electromagnetic radiation is defined as albedo.
