Final answer:
The 'Integrative Process' credit category is new to LEED v4 and was formerly part of the 'Innovation in Design' category in LEED v2009, reflecting the importance of integrated design for sustainability and building performance.
Step-by-step explanation:
The Integrative Process credit category is new to v4, and was previously part of the Innovation in Design category in v2009. This refers to the integration of sustainability efforts and the achievement of higher levels of building performance. The v4 version evolves from the previous versions by incorporating an integrative process that spans from the pre-design phase through occupancy and quantifies benefits from a whole-building perspective.
