Green Roof Soil Thermal Conductivity

The thermal conductivity for soil was only used on the acob roof analysis since the uppermost sensor used on the green roof analysis 2bn was sitting in 1 5 inches of soil above the surface of the ceiling.

Green roof soil thermal conductivity.

The thermal conductivity of the green roof soil in i p units ranged between 1 2 at 0 saturation and 2 84 at 82 saturation. The study concludes that green roofs can lower thermal losses. Construction with a thick soil layer of 0 5 0 9 m thermal losses are almost half compared. Green roofs with silt clay soil required more than twice the amount of soil moisture than green roofs with sand to achieve similar roof heat transfer rates.
