2-Dimensional Steady State Thermal Analysis is performed on simple assemblies to identify the thermal transmittance (U value) and assess the condensation risk.  What is the thermal transmittance? It’s composed of the three modes of heat transfer: thermal heat conductivity, thermal heat conductivity, and radiation thermal.   It’s often expressed as U values (for windows, curtain walls, skylights, and other glazing).

These NFRC-compliant simulations are nationally accepted as an alternative of the expensive laboratory testing of fenestration. Also, this type of analysis can yield SHGC of the fenestration (measure of solar direct gain in windows) , with the popular software we use.
