Worked on the NREL/OpenStudio-HPXML repository to enhance HVAC and water heater modeling, focusing on improving simulation accuracy and workflow efficiency. Standardized water flow curves for two-speed heat pumps by setting them to constant values, which removed curve-fitting variability and ensured consistent HVAC performance modeling. Refined electric water heater UA calculations to account for fractions of heated and unheated water, aligning tank loss estimates with the UniformEnergyFactor metric. Updated related documentation and tests to reflect these changes, using Ruby and Markdown. Emphasized code refactoring, energy modeling, and testing to deliver more reproducible results and streamlined analysis for end users.

Jul 1, 2025July 2025 monthly work summary for NREL/OpenStudio-HPXML focusing on water heater modeling improvements and test/documentation updates. Delivered enhanced thermal loss estimation for electric water heaters by refining the UA calculation to account for fractions of unheated and heated water, and introduced a debug comparison workflow with cleanup of extraneous debug output. Aligned energy performance with the UniformEnergyFactor (EF) metric by adding EF-based tank loss calculations, updating related documentation, and refreshing tests to reflect the new UA/U-value behavior.
