PROFILE
Richard Raustad
Contributed to the NREL/EnergyPlus repository by enhancing both simulation accuracy and development workflows over a three-month period. Addressed critical bugs in HVAC system modeling, including correcting ZoneList energy demand calculations and refining cooling tower sizing logic to improve reliability and maintainability. Developed targeted unit tests in C++ to validate energy balance and prevent regressions, ensuring robust simulation results. Improved continuous integration processes by updating GitHub Actions workflows with YAML, enabling more comprehensive regression testing for external pull requests. These efforts reduced manual QA overhead, accelerated safe integration of community contributions, and supported more accurate energy modeling for HVAC system simulations.
