EDGE-Expert Exam Dumps - EDGE GBCI EDGE Questions and Answers

In the CBCI EDGE curriculum, the embodied carbon assessment for existing buildings is handled differently from new construction. The key principle is that the existing building fabric is treated as already “sunk” and is not counted again in the embodied carbon calculation. This means elements such as the existing roof construction do not increase embodied carbon in the EDGE assessment for a retrofit project, because EDGE focuses on what is newly added or replaced as part of the upgrade scope.

Embodied carbon in EDGE is driven by the quantities and types of new construction materials introduced through the retrofit, such as added insulation, new wall or roof layers, new glazing, new finishes, or other building-material interventions. Therefore, the factor that increases embodied carbon is the inclusion of new materials in the retrofit scope.

While external shading devices can indeed add embodied carbon because they are additional materials, the most accurate and complete statement in the options is the broader one: any new materials added during the retrofit increase embodied carbon. New mechanical systems are generally treated under operational energy impacts rather than being core contributors in the EDGE embodied carbon in materials calculation.

According to the CBCI EDGE curriculum and EDGE certification workflow, the responsibility for entering and adjusting default improved case values in the EDGE software lies primarily with the Client or the Client’s appointed EDGE Expert during the design phase. The improved case represents the proposed energy, water, and materials efficiency strategies that go beyond the baseline case. Therefore, it must accurately reflect the design intent, specifications, and selected green measures for the project.

The Auditor’s role is not to create or modify the improved case on behalf of the Client, but to independently review, verify, and validate the inputs against supporting documentation. This ensures impartiality and maintains the integrity of the certification process. Allowing the Auditor to adjust values directly would compromise the independent third-party verification principle embedded in the EDGE certification framework.

The EDGE Operations and Maintenance Team is relevant mainly for operational performance after project completion, not for inputting design-stage software data. Similarly, the Certification Provider oversees the process but does not alter project-specific software inputs. Therefore, the correct process is that the Client adjusts the improved case values, and the Auditor reviews them for compliance and accuracy.

In EDGE, measures are evaluated for their impact on energy, water, and embodied energy in materials, the three core pillars of the standard. For an air-conditioned hospital with a water-cooled chiller, the measure must affect all three areas to be the correct answer. The EDGE User Guide provides detailed descriptions of each measure’s impact: "Variable speed drive (VSD) pumps in HVAC systems, such as those used in water-cooled chillers, impact energy by reducing electricity consumption through load modulation, water by optimizing the chiller’s cooling water circulation (reducing water use in the cooling tower), and materials because their installation may involve additional components with embodied energy, such as the VSD unit itself" (EDGE User Guide, Section 4.2: Energy Efficiency Measures). Option C, variable speed drive pumps, thus impacts all three areas: energy (reduced electricity use), water (less cooling tower water loss), and materials (embodied energy in the VSD equipment). Option A (insulation of the roof) affects energy (reduced cooling load) and materials (embodied energy in insulation), but not water: "Roof insulation reduces energy demand but does not directly impact water consumption" (EDGE User Guide, Section 4.1: Insulation Measures). Option B (water-efficient urinals) impacts water (reduced consumption) and potentially materials (embodied energy in fixtures), but not energy: "Water-efficient urinals save water but have no direct energy impact in EDGE calculations" (EDGE User Guide, Section 5.2: Water Efficiency Measures). Option D (water-efficient dishwashers) also affects water and materials, but not energy in this context: "Water-efficient dishwashers reduce water use, but their energy impact is minimal unless they include hot water savings, which is not specified for hospital dishwashers in EDGE” (EDGE Methodology Report Version 2.0, Section 4.2: Water Savings Calculations). The EDGE Methodology Report further confirms: "VSD pumps in water-cooled chillers are unique in affecting all three EDGE metrics—energy through efficiency, water through reduced cooling tower evaporation, and materials through the embodied energy of the equipment" (EDGE Methodology Report Version 2.0, Section 5.1: Energy Efficiency Metrics). Thus, variable speed drive pumps (Option C) is the measure impacting energy, water, and materials.

The issuance of certificates in the EDGE certification process is a defined responsibility assigned to specific roles. The EDGE Certification Protocol states: "The EDGE Preliminary Certificate, awarded at the design stage, is issued by the EDGE Certification Provider after the Auditor submits a recommendation for certification based on the design audit. The Certification Provider reviews the Auditor’s report and, if compliant, issues the certificate" (EDGE Certification Protocol, Section 3.3: Certification Decision). Option C, Certification Provider, aligns with this process, as entities like GBCI are responsible for issuing certificates. Option A (Auditor) is incorrect, as Auditors only recommend certification: "The Auditor’s role is to provide a recommendation, not to issue the certificate" (EDGE Expert and Auditor Protocols, Section 2.2: Roles of EDGE Auditor). Option B (Expert) is also incorrect, as Experts advise on design, not certification: "EDGE Experts assist with project design and self-assessment, not certification issuance" (EDGE Expert and Auditor Protocols, Section 2.1: Roles of EDGE Expert). Option D (Operations and Management Team) is wrong, as this team supports the overall program, not individual certifications: "The EDGE Operations and Management Team oversees program development, not certificate issuance" (EDGE Certification Protocol, Section 1.3: Program Structure). Thus, the Preliminary Certificate is issued by the Certification Provider (Option C).

The CBCI EDGE curriculum explains that EDGE uses a simplified, quasi-steady-state approach to estimate building energy performance. To keep the method practical and consistent across many countries, EDGE relies on climate datasets that represent typical conditions over longer time steps rather than detailed hour-by-hour weather files used in dynamic simulation tools. In EDGE, the local climate inputs applied in the baseline and improved case calculations are based on monthly climate averages, including outdoor minimum and maximum temperatures, humidity, wind conditions, and solar radiation.

Monthly averages provide an effective balance between accuracy and usability. They capture seasonal variation that strongly influences heating and cooling loads, while avoiding the complexity and data intensity of hourly modeling. Weekly averages are not used because they add complexity without providing the standardized global consistency that EDGE aims for. Annual averages would be too coarse, because they would hide seasonal peaks and understate the impact of envelope and HVAC efficiency measures.

Therefore, the correct statement is that EDGE calculations use monthly average climate information for the key weather parameters listed.

The EDGE software uses a Base Case to establish a benchmark for resource consumption, tailored to local conditions. The EDGE Methodology Report explains how the Base Case is constructed: "The Base Case for external wall materials in hotels is determined using data from market surveys of typical building practices in the project’s country, supplemented by national building performance codes where available. This ensures the baseline reflects local construction norms and regulatory standards" (EDGE Methodology Report Version 2.0, Section 3.1: Base Case Determination). Option A matches this description by referencing typical building practices and national codes. Option B incorrectly refers to global practices and international codes, which EDGE does not use, as the software prioritizes local context. Option C, focusing on corporate specifications, is not part of the Base Case methodology, as the Base Case is standardized, not project-specific. Option D, involving local suppliers or accreditation, is irrelevant to how EDGE determines the Base Case, which relies on broader market data rather than supplier-specific information.

The EDGE software requires users to select a building type (typology) to model resource consumption accurately, and the choice depends on the scope of the certification. In this scenario, a tenant on the third floor (an office floor) of a medium-rise building seeks EDGE certification. The EDGE User Guide provides guidance on selecting building types for tenant spaces: "When a tenant within a larger building seeks EDGE certification, the building type should reflect the tenant’s space. For an office tenant on the third floor of a mixed-use building, the ‘Office’ typology should be selected, as the certification applies only to the tenant’s space, not the entire building, unless the whole building is being certified" (EDGE User Guide, Section 2.2: Project Setup). Option A, Office, aligns with this guidance, as the tenant’s space is an office. Option B (Retail) is incorrect, as the retail floors are on the first two levels, not the third: "Retail typology would apply if the tenant space were on the retail floors, not the office floors" (EDGE User Guide, Section 2.2: Project Setup). Option C (Mixed-use) is also incorrect, as this typology applies to the entire building, not a single tenant space: "Mixed-use typology is used when the entire building, including all uses (e.g., retail and offices), is being certified, not for individual tenant spaces" (EDGE Methodology Report Version 2.0, Section 2.1: Calculation Approach). Option D (Core and Shell) is typically used for buildings certified up to the core and shell stage, not for tenant fit-outs: "Core and Shell typology applies to buildings certified without tenant fit-outs, focusing on the building envelope and systems, not individual tenant spaces like an office" (EDGE Certification Protocol, Section 1.2: Scope of EDGE Standard). The EDGE User Guide further clarifies: "For tenant-led certifications, the typology should match the tenant’s use—e.g., ‘Office’ for an office tenant—even if the building has multiple uses, ensuring the Base Case reflects the tenant’s specific consumption patterns” (EDGE User Guide, Section 2.2: Project Setup). Since the tenant on the third floor operates an office, the Office typology (Option A) is the correct choice for EDGE certification.

Under the CBCI EDGE curriculum, EDGE Certified and EDGE Advanced are one-time certifications and do not require renewal. EDGE Zero Carbon is treated differently because it depends on ongoing operational conditions, especially how the building’s remaining operational emissions are addressed through renewable electricity and, where applicable, offsets. For this reason, EDGE Zero Carbon certificates include an expiration date and require renewal to confirm that the carbon strategy remains valid over time.

The EDGE Zero Carbon rules specify different expiration periods depending on how the project achieves the renewable electricity and emissions balance. When a project meets the EDGE Zero Carbon criteria fully on-site, including the generation of on-site renewable electricity, the certificate expires after four years. This longer validity period reflects the higher confidence and stability associated with on-site renewable generation that is physically tied to the building and less dependent on external contracts or market instruments.

By comparison, projects that rely on purchased off-site renewable electricity and or carbon offsets have a shorter certificate validity period because procurement terms and availability can change. Therefore, for a fully on-site renewable electricity EDGE Zero Carbon project, the correct expiration period is four years.

The EDGE App relies on location-specific climate data to calculate resource savings, but not all cities are listed. The EDGE User Guide provides guidance for such cases: "If the project city is not listed in the EDGE App, the user should choose the closest city to the project location that is available in the database. If necessary, the user can edit the climate data (e.g., temperature, humidity) to better reflect the project’s actual conditions, ensuring accurate calculations" (EDGE User Guide, Section 2.2: Project Setup). Option B, choose the closest city and edit the climate data if necessary, directly matches this protocol. Option A (write to EDGE Certifier and wait) is incorrect, as this is not a required step: "Users are not required to request new cities; they can proceed by selecting the closest city" (EDGE User Guide, Section 2.2: Project Setup). Option C (select any city in the same climate zone globally) is too broad and inaccurate: "Choosing a city from a different region, even in the same climate zone, may lead to incorrect assumptions about local practices and climate" (EDGE Methodology Report Version 2.0, Section 3.2: Climate Data Inputs). Option D (choose the capital city) is also incorrect unless it is the closest: "The capital city should only be selected if it is the nearest available option in the database" (EDGE User Guide, Section 2.2: Project Setup). Thus, the correct protocol is to choose the closest city and edit climate data (Option B).

According to the CBCI EDGE protocols and auditor requirements, EDGE Auditors are responsible for maintaining proper records of the projects they audit. This obligation is part of the professional and ethical framework that ensures transparency, accountability, and traceability in the certification process. Auditors must retain documentation related to the design audit, site audit, calculations, correspondence, and supporting evidence reviewed during certification.

The requirement is not satisfied by merely reviewing documents and returning them to the client or transferring them to another party. The auditor must independently keep records, typically in electronic format, to allow for quality assurance checks, potential appeals, disputes, or oversight reviews conducted by the Certification Body or IFC. This retention obligation extends for a defined period after certification.

Options A and D are incorrect because the auditor cannot transfer full responsibility for record retention to the client or EDGE Partner. Option B is incorrect because reviewing without retaining records violates audit protocol requirements. Therefore, the accurate statement is that the auditor should keep the electronic format of the information about the project submission.
