Integrative Process
What the category rewards
Integrative Process (IP) rewards a team that studies how systems interact before design hardens. In LEED v4 BD+C it is a single-point credit; LEED v4.1 restructures the requirement (and elevates it toward prerequisite status), so confirm which version your exam targets before memorizing point values. The credit has two parts: an early design charrette and discovery-phase analysis of energy- and water-related systems.
Concepts to know
- Owner's Project Requirements (OPR) - measurable written goals against which every later analysis and commissioning activity is judged.
- Energy analysis: a simple box or massing model comparing at least two schemes (orientation, envelope, glazing, HVAC strategy) including life-cycle cost.
- Water analysis: a conceptual site water budget covering potable supply, fixture demand, irrigation demand, and rainwater/greywater reuse opportunities.
- The analysis must inform the design, not document a decision already made.
Traps
- IP is not commissioning and is not satisfied by a kickoff meeting or an integrated design charrette alone.
- Both energy and water analysis are required; doing only one earns nothing.
- A charrette held after schematic design is complete is usually too late to earn the credit.
- Submitting a consultant's report with no evidence that a design decision changed is a classic distractor.
Rule of thumb
Ask two questions of every IP scenario: when did it happen (must be pre-design/discovery) and what changed (the analysis must alter a decision). If either answer is missing, treat the credit as failed.
