R - Values

e3bw · Posts: 1

Currently when you define a material as having an r-value as opposed to conductivity, density and specific heat it comes through to E+ as air - which is ok for internal materials but nor for external materials. Is there a way we can define an R-Value for material in Design Builder and come through to E+ as a " Material Regular-R"?

Starting from version 1.1.1, DesignBuilder allows you to define materials as R-values which can be at the surface of the construction.
