January 2026 — AixLib: Delivered the solar radiation transmission enhancements and model clarity improvements. Introduced a new parameter 'g' to refine transmission correction factors, refactored the model by renaming 'Ag' to 'A' for consistency with the new parameter, and updated documentation to reflect the removal of an obsolete window model parameter. Also fixed historical documentation by correcting the commit history year from 2025 to 2026. These changes improve model accuracy, readability, and maintainability for downstream simulations.

December 2025 monthly summary for RWTH-EBC/TEASER: Focused on delivering precise energy-model exports and improving code quality. Key feature delivered was heating profile export enhancements with validation for BESMod, including alignment of parameter definitions and clarified examples to reduce misconfigurations. Maintained and improved test coverage to reflect correct heating profile calculations. Completed code quality improvements through a version bump (1.3.0 -> 1.3.1) and whitespace cleanup to enhance readability and maintainability. These changes increase modeling accuracy, reliability of exports, and streamline future releases.

Concise monthly summary for 2025-11 focusing on RWTH-EBC/TEASER: Key features delivered, major bugs fixed, overall impact, and technologies demonstrated.
