What or who determines the baseline assumptions in EDGE?

The baseline assumptions in EDGE software, known as the Base Case, are critical for calculating resource savings and are determined using standardized data. The EDGE Methodology Report explains: "Baseline assumptions in EDGE, referred to as the Base Case, are determined by market surveys of typical construction practices in the project’s country, reflecting common materials, systems, and design practices for the selected typology and location" (EDGE Methodology Report Version 2.0, Section 3.1: Base Case Determination). Option C, market survey of typical construction practices, aligns with this methodology. Option A (EDGE software users) is incorrect, as users do not set the baseline; they input project-specific data. Option B (EDGE Auditors) is also incorrect, as auditors verify compliance, not establish baselines. Option D (market survey of best construction practices) is wrong because EDGE uses typical practices, not best practices, to create a realistic benchmark, as clarified in the EDGE User Guide: "The Base Case reflects typical local practices, not best practices, to ensure a fair comparison for resource savings" (EDGE User Guide, Section 2.3: Using the EDGE App).
