Green Roof Soil Thermal Conductivity

For the acob analysis the soil was considered to be fairly saturated at the bottom of the soil layer where the soil analysis was done.

Green roof soil thermal conductivity.

With those of a bare roof. The best net heat flux gains for vegetated green roofs were 4 7 w m 2 for the sand roof and 7 8 w m 2 for the silt clay roof. The study concludes that green roofs can lower thermal losses. In present study f is the thermal conductivity of air as a fluid component of a dry soil.

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. Conductivity of green roofs bioresources 14 4 8573 8599. 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. 8576 𝜅2𝑃 𝑓 1 𝑓 1 𝜅2𝑃 1 1 1 where s and f w mk are the thermal conductivities of solid and fluid phases respectively.
