The EDGE software uses a simplified approach to calculate energy consumption, focusing on accessibility and speed for users in emerging markets. The EDGE Methodology Report explains the calculation method: "Energy consumption in EDGE is calculated using steady state calculations, which assume constant conditions over a period to estimate energy use for heating, cooling, lighting, and other systems. This method simplifies the modeling process while providing sufficiently accurate results for the purposes of EDGE certification" (EDGE Methodology Report Version 2.0, Section 5.2: Energy Calculation Methods). Option B, steady state calculations, directly matches this approach. Option A (hourly simulation) is incorrect, as EDGE does not use dynamic simulations: "EDGE does not employ hourly simulations, which are more complex and resource-intensive, as the goal is to provide a fast and simple tool" (EDGE User Guide, Section 2.1: EDGE Software Overview). Option C (quasi-steady state calculations) is also incorrect, as EDGE does not use this intermediate method: "Quasi-steady state methods, which account for some dynamic effects, are not used in EDGE to maintain simplicity" (EDGE Methodology Report Version 2.0, Section 5.2: Energy Calculation Methods). Option D (cooling and heating degree days) is a metric used to estimate climate impact, not the calculation method: "Degree days are inputs to the steady state calculations, not the method itself" (EDGE User Guide, Section 3.2: Climate Data Inputs). Thus, steady state calculations (Option B) are used for energy consumption in EDGE.

Variable speed drives (VSDs) are a recognized energy efficiency measure in EDGE for optimizing HVAC system performance. The EDGE User Guide explains their role: "Variable speed drives in HVAC systems, such as those used in fans and pumps, adjust the motor speed to match the load demand, significantly reducing energy consumption compared to fixed-speed systems. This measure can achieve up to 30% energy savings in HVAC operations" (EDGE User Guide, Section 4.2: Energy Efficiency Measures). Option C, reduce energy consumption, directly aligns with this description. Option A (reduce the speed) and Option B (increase the speed) are partially correct in that VSDs adjust speed, but the primary benefit in EDGE is energy savings, not speed adjustment itself: "The goal of VSDs in EDGE is energy reduction through speed modulation, not speed adjustment as an end" (EDGE Methodology Report Version 2.0, Section 5.1: Energy Efficiency Metrics). Option D (reduce water consumption) is incorrect, as VSDs impact energy use, not water: "VSDs are an energy measure and do not directly affect water consumption in HVAC systems" (EDGE User Guide, Section 4.2: Energy Efficiency Measures). Thus, VSDs help reduce energy consumption (Option C).

EDGE Auditors must adhere to strict ethical guidelines to maintain independence and avoid conflicts of interest, particularly regarding payment structures that could influence their impartiality. The EDGE Expert and Auditor Protocols address payment terms explicitly: "An EDGE Auditor must confirm a fixed fee for their services that is independent of the final assessment result. Payment structures that tie fees to the success of certification, such as contingent payments, are prohibited to ensure the Auditor’s objectivity and to prevent any perception of bias in the audit process" (EDGE Expert and Auditor Protocols, Section 2.3: Conflict of Interest). The client’s offer of 50% payment for assessment and 50% upon successful certification violates this principle, as it makes part of the fee contingent on the outcome. Option A, confirm a fixed fee independent of the final assessment result, aligns with this ethical requirement, ensuring the Auditor’s impartiality. Option B (lodge a complaint with local authorities) is incorrect, as this is an overreaction and outside the Auditor’s role: "Issues related to payment terms should be resolved directly with the Client, not escalated to local authorities, which are unrelated to EDGE certification" (EDGE Expert and Auditor Protocols, Section 4.1: Audit Process). Option C (refer the developer to another Auditor) avoids the issue but does not address the ethical concern: "Referring the Client to another Auditor does not resolve the ethical violation of contingent fees, which applies to all Auditors" (EDGE Expert and Auditor Protocols, Section 2.3: Conflict of Interest). Option D (accept the terms) is unethical, as it compromises the Auditor’s independence: "Accepting payment terms tied to certification success, even if the project is likely to succeed, violates EDGE protocols and undermines the integrity of the certification process" (EDGE Certification Protocol, Section 3.1: Certification Process). The EDGE User Guide further emphasizes: "Auditors must maintain strict independence, ensuring their compensation is not influenced by the certification outcome, to uphold the credibility of EDGE certification" (EDGE User Guide, Section 6.5: Working with EDGE Auditors). Thus, the Auditor should confirm a fixed fee (Option A).

In the CBCI EDGE curriculum, the Share Subproject function is treated as a project administration permission, because it controls who can access a project or part of a project and what they are allowed to do inside the EDGE platform. Sharing affects project confidentiality, accountability for inputs, and control of documentation, so it is restricted to the user role that holds administrative authority over the project workspace.

The Owner role is the primary controlling role in an EDGE project. The Owner can manage access, invite or remove team members, and assign appropriate permissions for collaboration. This is consistent with how EDGE separates responsibilities: the client side controls project data entry, collaboration, and submissions, while verification roles remain independent.

Auditors and Certifiers are part of the independent third-party assessment pathway. Their access is typically granted for review and verification purposes, not for administering who the project is shared with. A Reviewer role, where used, is also generally a read-only or limited-access role and does not have authority to share or manage subprojects.

The EDGE definition of a green building is a building that uses less resources quantified as

A. 20% less energy, 20% less water, and 20% less embodied carbon in materials as compared to a local benchmark.

B. 40% less energy, 20% less water, and 20% less embodied carbon in materials as compared to a local benchmark.

C. 20% less energy, 20% less water, and 20% less embodied carbon in materials as compared to similar buildings in other countries.

D. 20% less energy, 20% less water, and 20% less waste as compared to a local benchmark.

Answer: A

According to the CBCI EDGE curriculum, the foundational definition of an EDGE Certified green building is one that achieves a minimum of 20 percent savings in energy, 20 percent savings in water, and 20 percent reduction in embodied carbon in materials when compared to a local baseline or benchmark defined within the EDGE software. This local benchmark reflects standard building practices, climatic conditions, and typical construction methods for the specific country where the project is located.

The 20-20-20 threshold represents the minimum performance requirement for achieving EDGE Certified status. Higher performance levels, such as EDGE Advanced, require at least 40 percent energy savings but still maintain the 20 percent thresholds for water and materials. Therefore, option B reflects the requirement for EDGE Advanced, not the base definition of a green building under EDGE.

Option C is incorrect because EDGE comparisons are always made against a locally defined baseline, not buildings in other countries. Option D is incorrect because EDGE evaluates embodied carbon in materials, not waste reduction as a core certification metric. Therefore, the correct definition aligns with option A.e, the user type that has access to the Share Subproject function is the Owner.

Within the CBCI EDGE curriculum, greywater is defined as relatively low-contamination wastewater generated from bathing and handwashing activities, typically coming from fixtures such as showers, wash basins, and bathtubs. This type of wastewater is considered suitable for recovery and reuse in certain non-potable applications, depending on local codes and the treatment approach, because it does not contain toilet waste.

A water closet WC produces blackwater, not greywater. Blackwater contains fecal matter and urine and therefore has a much higher pathogen load and organic content. Because of this, it requires more stringent treatment processes and different health and safety controls compared with greywater systems. In EDGE water measures, greywater reuse calculations and strategies are based on sources like showers and hand basins, while toilet discharge is excluded from greywater source assumptions.

Therefore, among the listed fixtures, the one that does not produce greywater in EDGE is the water closet WC, making option D the correct answer.

The CBCI EDGE curriculum distinguishes clearly between eligibility to attend the EDGE Expert training and eligibility to be licensed or recognized as an EDGE Expert. For attending the training itself, the curriculum states that there is no formal prerequisite regarding qualifications. This is because the training is designed to be accessible to a wide range of participants, including professionals who may support EDGE projects indirectly, students, and stakeholders who want to understand the EDGE standard and the certification process.

The stricter requirements such as having a bachelor’s degree or having specific construction industry experience relate to later steps in the pathway, especially when a participant aims to progress from training attendance to formal credentialing, licensing, or professional recognition as an EDGE Expert. In other words, options B, C, and D reflect possible qualification pathways for becoming eligible for the credential, not for simply joining the training. Therefore, when the question asks specifically about the eligibility requirement to attend an EDGE Expert training, the correct answer is that there is no prerequisite regarding qualifications.

In the CBCI EDGE curriculum, the EDGE Baseline is not fixed permanently because construction practices, typical system efficiencies, and national or city regulations evolve over time. To ensure that EDGE continues to represent a realistic and fair comparison against “standard practice” in each location, the EDGE Baseline is periodically reviewed and updated. The curriculum explains that baseline reviews are undertaken every 3 to 5 years when needed, and this review can include updates to the geographic coverage of EDGE, such as adding new countries or refining baselines where market conditions or codes have changed.

This review cycle helps maintain the credibility of the 20 percent savings thresholds by making sure the baseline remains aligned with what is commonly built in a given market. If baselines were updated too frequently, it would create instability for project planning; if updated too rarely, the baseline could become outdated and no longer reflect typical practice. The 3 to 5 year interval balances stability with relevance, ensuring that EDGE benchmarking stays accurate across different regions and over time.

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).

Within the CBCI EDGE curriculum, wall material selection affects not only embodied carbon under the materials category but also operational energy performance. The thermal properties of wall assemblies, including U-value, thermal mass, conductivity, and insulation levels, directly influence the building’s heat transfer characteristics. These factors determine how much heat enters or escapes through the building envelope, thereby affecting cooling and heating loads.

When wall materials provide improved insulation or higher thermal mass, they reduce unwanted heat gains in hot climates and heat losses in cooler climates. This results in lower energy demand for HVAC systems. In the EDGE software, envelope performance improvements are reflected in the energy calculations under the improved case scenario, contributing to overall percentage energy savings.

Window to Wall Ratio is a geometric design parameter and is not determined by wall material choice. Internal heat gains are primarily influenced by occupants, lighting, and equipment rather than wall composition. Solar Heat Gain Coefficient refers specifically to glazing performance, not opaque wall materials. Therefore, aside from embodied carbon impacts, wall material selection most directly affects the building’s energy consumption.

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.
