The design charrette must occur no later than which phase in order to earn the Integrative Process Credit, Option 2: Design Charrette?
The LEED for Homes Rating System (v4) includes the Integrative Process (IP) Credit: Integrative Process, Option 2: Design Charrette, which requires a collaborative meeting early in the design process to integrate green strategies.
According to the LEED Reference Guide for Homes Design and Construction (v4):
IP Credit: Integrative Process, Option 2: Design Charrette (1 point)
Conduct a design charrette no later than the schematic design phase to ensure early integration of green strategies across all project aspects, including energy, water, and materials.

The LEED v4.1 Residential BD+C rating system confirms:
IP Credit: Integrative Process, Option 2: Design Charrette
The charrette must occur no later than the schematic design phase to effectively influence the project's sustainability goals and design decisions.

The correct answer is Schematic Design (Option B), as the charrette must occur by this phase to ensure early integration of sustainable strategies.
Why not the other options?
A . Bid Solicitation: This is a post-design phase, too late for the charrette's purpose.
C . Design Development: This is later than schematic design, reducing the charrette's impact on early design decisions.
D . Construction Drawings: This is a final design phase, far too late for integrative planning.
The LEED AP Homes Candidate Handbook emphasizes IP credits, including the timing of the design charrette, and references the LEED Reference Guide for Homes Design and Construction as a key resource. The exam is based on LEED v4, ensuring the relevance of the schematic design phase.
