In March 2025, the team delivered targeted CI and testing infrastructure enhancements for NREL/ComStock, significantly improving reliability, visibility, and feedback speed, while also addressing network-restricted build constraints for NREL/OpenStudio. The effort reduced flaky tests, strengthened reporting, and improved pipeline maintainability across repositories.

February 2025 monthly summary for NREL/ComStock focused on delivering a robust, scalable data processing pipeline, stronger CI/CD, and enhanced test integrity. The month delivered concrete business value through pipeline improvements, reliability upgrades, and broader test coverage with tolerance-based validations and revised baselines.

January 2025 monthly summary for NREL/OpenStudio: delivered targeted bug fixes and code quality improvements that stabilize story handling, ensure reliable tests, and reduce maintenance overhead, contributing to improved software reliability and velocity.

December 2024 performance highlights include delivering a centralized, automated model file transfer workflow for NREL/ComStock that unifies local-to-S3 transfers across multiple project versions/releases, updates YAML inputs, and aligns S3 output paths. The implementation supports p2/p3/p4 stages with robust path and metadata configuration, and reflects a migration towards a centralized mechanism after deprecating legacy scripts. HPC processing was significantly improved by controlling parallelism, ensuring correct S3 key/path handling under high concurrency, and optimizing transfer checks to avoid redundant work (including core-limiting to 50 cores and optional use of s5cmd). Additionally, a Red Hat compatibility fix was applied to NREL/OpenStudio to align the Radiance MD5 hash with the updated component version. These efforts collectively improve data reliability, pipeline throughput, and maintainability, enabling faster, scalable data provisioning for downstream analyses and reporting.

In November 2024, the team delivered key release and data processing improvements across the OpenStudio and ComStock repositories, strengthening release reliability, data quality, and testing readiness. OpenStudio updates focused on packaging for RC2/RC3 and removing prerelease tags to advance a stable release, with linked gem/extension/standards updates and CMakeLists adjustments, plus published OpenStudio 3.9.0 release notes in Markdown and PDF. ComStock enhancements delivered robust failure summarization, improved data processing robustness, and leaner error handling, contributing to more reliable upgrades and exports.

OpenStudio monthly summary for 2024-10: Implemented an OpenStudio Gem Version Update for Build Stability by updating the build configuration to reference newer OpenStudio gems, and aligning versioning information and download URLs across Windows, macOS, and Linux to ensure builds pull the latest gem releases. This change reduces gem-version drift, enhances CI and local build reliability, and simplifies maintenance for downstream users.
