LEED v4 to v5 High-Level Crosswalk

Scope boundary

This is a category and major-theme map, not a credit-by-credit crosswalk. Changed means that the validated local sources visibly frame or organize the theme differently; it does not establish a detailed requirement change.

Official comparison evidence

LEED BD+C v4 to v5 Summary of Changes is now the primary source for the high-level BD+C comparison. Its detailed category tables are preserved as page images, so they support the themes below but are not being transcribed into a credit-by-credit crosswalk.

Next Comparison Gate

The first cross-source atomic batch should compare integrative process, commissioning, energy metering, and climate resilience. Each resulting note must keep LEED v4 foundational statements separate from LEED v5 requirement and guidance statements.
