Hi there, I'm working on a project about applying a Transparent Insulation Material (TIM) between two glazing panes. I've already got an regression formula of the dynamic conductivity through CFD calculation and got its BSDF through Radiance. Now, I want to model this material in E+ by combining the thermal property form CFD and optical property from Radiance to conduct a building performance simulation.

For the thermal part, the conductivity of the martial is determined by temperature difference between the two glazing panes and mean temperature of them. By using EMS, I know, I might be able to set two sensors to read the outside and inside surface temperatures of these two glazing panes. But I can't find an actuator related to the conductivity of a material. In this case, is it possible to adjust the conductivity of this material?
