Green Roof Ratio Of Total Reflected To Incident Electromagnetic Radiation

The ratio of electromagnetic radiation reflected from a surface relative to the amount of radiation incident on it.

Green roof ratio of total reflected to incident electromagnetic radiation.

The ratio of total reflected to incident electromagnetic radiation is defined as albedo. The ratio of total reflected to incident electromagnetic radiation is defined as albedo. The inclination of the instrumentation was then adjusted to 17 the same as the roofs pitch. The roof albedo is represented by the 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 of a bitumen tar gravel roof. 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. 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. Incident electrom agnetic r adiation is defined.

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. 1 latent heat loss and 2 enhanced reflectivity of incident solar radiation. The ratio of total reflected to. Enhanced r efle ctivity of incident solar radiation.

According to this method the measurement uncertainty can be considered around 7. The ratio of total reflected to incident electromagnetic. However planted roofs suffered less heat gain during the day. Green roofs cool through latent heat loss and improved reflectivity of incident solar 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. 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. By green roofs annual total building runoff can be. There are two factors which make green roofs cool.

The ratio of total reflected to incident electromagnetic radiation is defined as albedo castleton 2010 1583.
