Mass Timber Cuts Embodied Carbon in High Seismic Middle School Study
A whole building life cycle assessment published by WoodWorks compares the mass timber replacement facility for The Bush School in Seattle against a composite steel baseline, demonstrating how structural timber and exposed surfaces lower upfront embodied carbon within high seismic zones.

Mass Timber Shaft Walls Replace Concrete Cores in Multi-Story Buildings
Structural guidelines and building code provisions now clarify how cross-laminated timber and light-frame wall assemblies can meet fire-resistance ratings for multi-story elevator and stair shafts. By eliminating concrete and masonry cores, project teams cut construction schedules, resolve differential wood shrinkage, and reduce structural weight.
