As of version 2022.d, in CYPETHERM programs with the EnergyPlus™ calculation engine, the thermal properties between the frame and glazing junction and between the frame and opaque panels or blind box can be defined (stated in standard EN ISO 10077-1:2020), in the definition of the opaque fraction for glazed openings and skylights.
The programs allow the users to define the length and linear thermal transmittance for the couplings in each type of opening, offering an assistant with common values to facilitate the definition.
