PROFILE
Allen
During a two-month period, Alex Allen enhanced the NREL/ComStock repository by developing features focused on energy-efficient HVAC control and robust testing. Alex implemented occupancy- and space-type-based HVAC setback controls, enabling dynamic heating setpoints based on real-time occupancy and space usage, using OpenStudio and Ruby scripting. He introduced new configuration arguments and helper methods for schedule manipulation, supporting more accurate energy modeling. In addition, Alex refactored optimum start logic for HVAC upgrades and expanded test coverage, improving code maintainability and reducing regression risk. His work demonstrated depth in backend development, energy modeling, and software testing, resulting in more reliable simulations.

Apr 1, 2025April 2025: Implemented occupancy- and space-type-based HVAC setback control feature in NREL/ComStock to optimize energy use by adjusting heating setbacks based on occupancy and space types. Added new configuration arguments for setback modifications and their values, along with helper methods for schedule manipulation to adjust heating setpoints during unoccupied periods. This lays the groundwork for occupancy-driven energy performance modeling and supports ongoing energy-efficiency initiatives.
