For modeling window films, you first have to determine what´s the effect in the U value and Solar Heat Gain Coefficient. LBNL Window allows you to do U value and SHGC calculations for different Insulated Glass Assemblies, but does not have the built-in capability of modeling window films.
I suggest that you become familiar with LBNL Optics software. Here´s the link https://windows.lbl.gov/software/optics/optics.html. Download the software, read the manual, and make some testing for yourself. Optics has glass and films libraries and allows you to build assemblies with them. After you make a glass/film assembly in LBNL Optics you can then import it within LBNL WINDOW to model either single, double, or triple glass assemblies. In Energyplus you enter the data for either a simplified or complex fenestration object, but you need to enter accurate data that was either previously calculated or from a product manufacturer.
I hope this is useful for you. Best Regards.
