Integrative Strategies
Green building starts before design
Integrative strategies reward teams that treat a building as a system rather than a stack of unrelated checklists. The formal vehicle is the Integrative Process credit, worth 1 point in BD+C and ID+C. It requires two things: a preliminary discovery analysis of energy and water systems completed before schematic design, and at least one cross-disciplinary workshop with owner, architect, engineers, contractor, and facilities staff.
The energy analysis is not a full simulation; simple box modeling of massing, orientation, envelope, and HVAC strategy is acceptable. The water analysis considers indoor fixtures, outdoor irrigation, and process water, and looks for reuse opportunities. Documentation is a short narrative showing what was analyzed, what was decided, and how the decision changed the design - for example, orienting the long axis east-west to cut cooling load while improving daylight.
Concepts behind the credit
Systems thinking means one decision retunes many credits: shading reduces cooling energy (Energy and Atmosphere) and glare (Indoor Environmental Quality). Early goal setting produces the Owner's Project Requirements (OPR), which the design team answers with a Basis of Design (BOD) and the commissioning authority verifies against. Life-cycle cost analysis - first cost plus operating cost over time - is the standard economic lens.
Traps
- The credit must be earned before schematic design, not during design development.
- Integrative Process is not Integrated Project Delivery; IPD is a contractual delivery method, not a LEED credit.
- It is worth only 1 point, but the underlying logic is tested throughout the exam.
Rule of thumb
Before the first line is drawn. If a question describes analysis happening after schematic design is complete, the credit is not earned.
