Green roof thermal conductivity
WebMay 27, 2024 · The thermal conductivity of pavement materials varies widely in the reported literature from 0.8 W/m•K to 2.0 W/m•K or greater, with similar values reported for dense-graded asphalt and concrete. Specific heat is the energy needed to raise a unit mass of a substance by one unit of temperature, typically expressed in units of J/kg•K. WebGreen roofs usually require a calculation time of about 10-15 years. Numerics: Due to the difficult moisture balance in the substrate layer, the calculation ...
