Ravi Jogineedi developed and integrated advanced phase change material (PCM) thermal storage modeling into the NREL/EnergyPlus repository, enabling more accurate simulation of PCM-based energy storage systems. Over eight months, Ravi designed new IDD objects, refactored core C++ modules, and enhanced plant loop integration to support PCM workflows. He improved input validation, error handling, and documentation, while implementing autosizing, SOC-based control, and multi-fluid property support. Through targeted bug fixes and code refinement, Ravi strengthened simulation fidelity and maintainability. His work combined C++, IDF scripting, and energy systems modeling to deliver robust, extensible PCM storage features for building energy simulation.
