Appendix E: LEED v4 Similarities

The IWBI and USGBC share similar certification processes and feature intents, particularly as related to air quality and daylighting. Because of their shared intentions, attainment of WELL features can help achieve certain LEED credits. However, due to differences in structure and small variations in content, complying with one does not guarantee credit for the other.
