Worked on the NREL/OpenStudio-HPXML repository to centralize electric panel capacity defaults by introducing a dedicated CSV file, panel_defaults.csv, as the authoritative source for panel nameplate ratings across various loads. This data management approach reduced configuration errors and improved consistency in simulation results by ensuring all loads reference a single, traceable dataset. The implementation focused on maintainability and future-proofing, making it easier for contributors to update or extend default values. Leveraging CSV for structured data storage, the work emphasized data governance and traceability, resulting in safer model configurations and streamlined onboarding for future development without addressing any reported bugs.
