There has been growing interest in using extensive green roofs for commercial and residential buildings in urban areas. Green roofs provide many benefits, including adding an additional insulation layer. The potential of this benefit depends on many factors, including the thermal properties of the green roof sub-strate. Thermal conductivity values of three substrates comprised primarily of scoria, crushed roof tileand bottom-ash were measured with steady-state and transient techniques under three moisture conditions. Specific heat capacities of the green roof substrates were also measured with a transient technique.Steady-state measurements were performed with a “k-Matic” apparatus while tra..View full abstract
