LEED v4 emphasizes the integrative process and early goal-setting for optimal performance outcomes. Specifically, under the Integrative Process credit and EA Prerequisite: Minimum Energy Performance, energy performance targets should be established during the programming phase:
“Establishing energy performance targets must occur during programming—before schematic design—to inform key decisions like massing, orientation, and system sizing.â€
“Beginning in discovery and continuing throughout the design phases, identify and use opportunities to achieve synergies across disciplines and the building’s energy and water-related systems.â€
The programming phase is when the Owner's Project Requirements (OPR) are defined, which guide energy goals, sustainability objectives, and user expectations.
Option A (Schematic Design) is too late to set foundational goals; it's used to explore options, not establish them.
Option B (Contract Administration) and C (Construction Documents) are implementation stages where design is largely finalized.
Correct phase: D. Programming, as this ensures energy targets are embedded from the beginning.
