Jeff Maguire enhanced the NREL/OpenStudio-HPXML repository by developing and refining HVAC and water heater modeling features over a two-month period. He standardized water flow curves for two-speed heat pumps, replacing variable curve fitting with constant values to improve simulation consistency and reproducibility. For electric water heaters, Jeff refined UA calculations to more accurately estimate thermal losses by accounting for fractions of heated and unheated water, and aligned tank loss modeling with the UniformEnergyFactor metric. His work, implemented in Ruby with supporting documentation in Markdown, improved the reliability, maintainability, and accuracy of energy modeling workflows without introducing new bugs.

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.
