PROFILE
Katelyn Stenger
Katelyn Stenger overhauled the HVAC upgrade configuration workflow in the NREL/resstock repository, focusing on modernizing and consolidating YAML-driven configuration files for SDR HVAC upgrades. She refactored upgrade logic and introduced reusable apply blocks, improving maintainability and reducing configuration drift. By updating simulation parameters and lookup tables, she enabled more accurate and scalable scenario analyses, broadening support for central AC, ASHP, and room AC upgrade paths. Her work leveraged Python, YAML, and Pandas for data management and timeseries analysis, aligning configuration structures with business goals and positioning the repository for future feature extensions and streamlined maintenance without introducing new bugs.
