The comparison of the EPA implementation of the J-E model (curves) with the full 3-D simulation (points) for a 2m depth foundation (a) and a 0.1m depth foundation (b); the comparison of the revised J-E model (flow and diffusivity corrections) results with those of the full 3-D simulation, for a 2 m depth foundation (c) and a 0.1m depth foundation (d); The comparison of the revised J-E model (curves, which include flow, diffusivity and mass conservation corrections) on indoor air concentration attenuation factor with detailed simulation results (points) for a 2m deep foundation (e) and a 0.1m depth foundation (f).
