The EDGE standard is designed to be a practical, focused tool for green building certification, emphasizing specific resource efficiency metrics. The EDGE User Guide describes its characteristics: "EDGE is a simple, fast, and smart tool for green building certification. It provides an intuitive interface with a powerful engine that accounts for local climate and building use (simple), identifies measures with the best return on investment (fast), and displays capital costs and payback periods (smart)" (EDGE User Guide, Section 1.1: Introduction to EDGE). Options A, C, and D align with these descriptions. However, Option B (holistic approach that takes into account wider sustainability issues) is not a characteristic of EDGE, as the standard focuses narrowly on energy, water, and embodied energy in materials, not broader sustainability issues like biodiversity or social equity. This is clarified in the EDGE Certification Protocol: "EDGE is not a holistic sustainability standard; it specifically targets resource efficiency in energy, water, and materials, excluding wider sustainability metrics such as indoor air quality or ecological impact" (EDGE Certification Protocol, Section 1.2: Scope of EDGE Standard). Thus, Option B is not a characteristic of the EDGE standard.

In the CBCI EDGE curriculum, a project can be certified for a defined scope when the owner is pursuing certification for only the area under their control, such as a tenant space, a single owned floor, or a partial building section. In this case, the “project” for EDGE purposes is the single-floor office area owned by Excellence Lawyers, not the entire high-rise. Therefore, the EDGE model must reflect the geometry and specifications of the certified scope only.

That means the envelope inputs should correspond to the office floor’s relevant boundaries: external façade walls (if any), glazing areas, and the resulting Window-to-Wall Ratio for that office scope. Internal partitions that adjoin other conditioned spaces are not treated the same as external envelope elements, because they do not drive the same heat transfer to the outdoors. The same principle applies to wall materials and lengths: they must represent the office area being certified, using the actual constructions that apply to that scope.

Modeling the whole building would incorrectly attribute systems and envelope characteristics outside the owner’s control and could distort the calculated savings and audit evidence. Hence, the correct approach is to model the office floor only.

During a site visit for post-construction certification, the EDGE Auditor relies on specific tools to verify compliance. The EDGE Expert and Auditor Protocols specify: "The primary resource for an EDGE Auditor during a site visit is the EDGE Auditor’s checklist, which provides a structured list of items to verify, including the implementation of selected measures, alignment with the self-assessment, and compliance with EDGE standards" (EDGE Expert and Auditor Protocols, Section 4.4: Site Audit Procedures). Option C, EDGE Auditor’s checklist, matches this description as the key resource guiding the audit process. Option A (EDGE software) is a tool for assessment, not a resource for the site visit: "The EDGE software is used for self-assessment and desk audits, not directly during site visits" (EDGE Certification Protocol, Section 3.2: Audit Requirements). Option B (roof insulation U-value) and Option D (Window to Wall Ratio) are specific data points the Auditor may verify, not primary resources: "U-values and WWR are elements to check, not tools for the Auditor" (EDGE Expert and Auditor Protocols, Section 4.4: Site Audit Procedures). The checklist ensures all aspects of the project are systematically reviewed, making it the primary resource (Option C).
