It's cool that you're optimizing and constructing this yourself. I want to do that myself one day. Since you're already using Python for some quick calculations, and are interested in continuing to model the interaction between your building and the environment, you might want to check out Ladybug, an open-source environmental and energy modeling library[1][2]. The honeybee-energy library has a wrapper for DOE's EnergyPlus simulation engine, and the ladybug, and ladybug-comfort libraries have a lot of useful methods for analyzing weather, and mapping it to thermal comfort.
