Worked on NREL/OpenStudio-HPXML to enhance HVAC monitoring and control by integrating new EMS sensor data, improving the accuracy of setpoint and heating-rate tracking while maintaining backward compatibility with existing logic. Applied Ruby and energy modeling expertise to streamline geometry generation, removing inferred ceilings from conditioned floor area calculations and aligning modeling definitions for greater consistency. Addressed a bug by eliminating redundant adiabatic ceilings between conditioned stories and updating unit tests to reflect revised simulation outputs. Emphasized robust unit testing and clear documentation throughout, resulting in improved data quality, reduced modeling complexity, and a more reliable workflow for building energy analysis.
