Sep 1, 2025In 2025-09 for NREL/EnergyPlus, delivered targeted enhancements and code quality improvements that advance model accuracy for ice storage operation and improve maintainability of the codebase. Key outcomes include refining the Ice Storage System Operation Schedule for the 5ZoneIceStorage_autosized.idf, updating ScheduleTypeLimits for On/Off, and adding TES Only off-peak setpoints to improve simulation accuracy under different energy pricing periods. A parallel, no-functional-change clang-format cleanup was applied to align the codebase with the latest style guidelines, enhancing readability and long-term maintainability without altering heat pump logic.
