NEW QUESTION # 27
Which of the following measures provides the most attractive solution in the EDGE software for a hospital?
- A. Insulation of external walls with 3% saving and 9 years payback
- B. External shading with 7% saving and 8 years payback
- C. Water-cooled chillers with 20% energy saving and 10 years payback
- D. Solar hot water system with a saving of 15% and payback of 6 years
Answer: D
Explanation:
In the EDGE software, the "most attractive solution" for a project, such as a hospital, is determined by balancing resource savings (energy, water, or materials) with financial payback periods, as these metrics are key outputs in the EDGE App Results Bar. The EDGE User Guide explains how to evaluate measures: "The EDGE software prioritizes measures that offer the highest resource savings with the shortest payback periods, making them the most attractive solutions for project teams. For hospitals, where energy and water demands are high due to continuous operation, measures with significant savings and faster payback are typically preferred" (EDGE User Guide, Section 2.4: Interpreting EDGE Results). Let's evaluate the options: Option A (external shading) offers 7% savings (likely energy, as shading reduces cooling loads) with an 8-year payback. Option B (insulation of external walls) provides 3% savings (also energy) with a 9-year payback.
Option C (solar hot water system) delivers 15% savings (energy, as it reduces the need for electric or gas water heating) with a 6-year payback. Option D (water-cooled chillers) achieves 20% energy savings but with a 10-year payback. The EDGE Methodology Report further clarifies: "For hospitals, measures like solar hot water systems are often attractive because they address high hot water demands (e.g., for sterilization, showers), offering substantial energy savings with relatively short payback periods due to consistent usage" (EDGE Methodology Report Version 2.0, Section 5.3: Energy Measures). Comparing the options, Option C has the second-highest savings (15%) and the shortest payback (6 years), making it more attractive than Option D (20% savings but 10 years payback), Option A (7% savings, 8 years), and Option B (3% savings, 9 years). The EDGE User Guide also notes: "A payback period of 6 years is generally considered attractive in EDGE, especially for measures with savings above 10%, as it aligns with typical investment horizons for building owners" (EDGE User Guide, Section 2.4: Interpreting EDGE Results). Additionally, for a hospital, hot water demand is significant, making solar hot water systems particularly effective: "Hospitals benefit greatly from solar hot water systems, achieving energy savings of 10-20% with payback periods often under 7 years due to high hot water usage" (EDGE Methodology Report Version 2.0, Section 4.2: Energy Savings Calculations). Thus, the solar hot water system (Option C) is the most attractive solution due to its balanced savings and shortest payback period.

NEW QUESTION # 28
Which of the following wall solar reflectivity indexes would be the most energy efficient in a hot climate?
- A. 0.2
- B. 0.3
- C. 0.4
- D. 0.7
Answer: D
Explanation:
In hot climates, reducing heat gain through building envelopes is a key strategy for energy efficiency, as emphasized in EDGE's green building design principles. The EDGE User Guide discusses solar reflectivity (measured by the Solar Reflectance Index, SRI) for walls and roofs, stating: "Higher SRI values indicate greater reflectivity, which reduces heat absorption and lowers cooling energy demand in hot climates. For walls in hot climates, an SRI of 0.7 or higher is recommended to maximize energy savings" (EDGE User Guide, Section 3.5: Passive Design Strategies). The options provided are 0.2, 0.3, 0.4, and 0.7. Since 0.7 is the highest SRI value among the choices, it reflects the most solar radiation, thereby reducing the cooling load andimproving energy efficiency in a hot climate, as per EDGE's guidance. Options A, B, and C have lower SRI values and would result in greater heat absorption, increasing energy use for cooling.
Reference:EDGE User Guide Version 2.1, Section 3.5: Passive Design Strategies.
NEW QUESTION # 29
Ceiling fans are an efficient way to increase air movement and therefore thermal comfort. Which of the following forms part of the evidence to demonstrate compliance at the design stage?
- A. Purchase receipts of the ceiling fans
- B. Computational Fluid Dynamics (CFD) assessment of all habitable spaces
- C. Photographs of the installed ceiling fans
- D. Manufacturer's data sheet of the ceiling fans
Answer: D
Explanation:
At the design stage (Preliminary Certification), EDGE requires specific documentation to verify that proposed measures, such as ceiling fans, will be implemented as claimed. The EDGE Certification Protocol specifies:
"For measures like ceiling fans at the design stage, the Client must provide evidence such as manufacturer's data sheets that detail the make, model, and specifications (e.g., power rating, air movement capacity) to confirm the fans meet the efficiency criteria for improving thermal comfort" (EDGE Certification Protocol, Section 3.2: Audit Requirements). Option C, manufacturer's data sheet of the ceiling fans, aligns with this requirement, as it provides the necessary specifications for verification. Option A (photographs of installed ceiling fans) is relevant at the post-construction stage, not design: "Photographs are required at the post- construction stage to confirm installation, not at the design stage" (EDGE Certification Protocol, Section 3.4:
Post-Construction Requirements). Option B (CFD assessment) is not required, as EDGE uses simplified calculations: "EDGE does not require CFD assessments for air movement; fan specifications suffice for design-stage verification" (EDGE Methodology Report Version 2.0, Section 5.5: Thermal Comfort Measures). Option D (purchase receipts) is also a post-construction requirement: "Purchase receipts verify installation, not design intent" (EDGE Certification Protocol, Section 3.4: Post-Construction Requirements).
Thus, the manufacturer's data sheet (Option C) is the correct evidence at the design stage.
Reference:EDGE Certification Protocol, Section 3.2: Audit Requirements, Section 3.4: Post-Construction Requirements; EDGE Methodology Report Version 2.0, Section 5.5: Thermal Comfort Measures.
NEW QUESTION # 30
Which of the following statements is correct about distinct user roles for an EDGE project team?
- A. A Project Viewer can assign or remove any user role and create edit delete projects in the EDGE software.
- B. A Project Administrator is the EDGE Auditor who manages the certification flow of the project on behalf of the owner.
- C. A Project Owner can track the project progress without the ability to edit.
- D. A Project Editor is typically someone from the design team who can edit the project details and documentation.
Answer: D
Explanation:
The CBCI EDGE curriculum explains that the EDGE software uses distinct user roles to control who can view, edit, and administer a project. A Project Editor is commonly a member of the design or sustainability team because this role is intended for day-to-day project development. Editors can enter and update project inputs, adjust improved case measures, and upload or manage supporting documentation required for certification. This aligns directly with option B.
Option A is incorrect because the Project Owner is not limited to viewing progress. The Owner role is the highest permission level within the project and typically includes the ability to edit project information as well as manage access. Option C is incorrect because a Project Viewer is a read-only role used for stakeholders who need visibility but should not change anything; viewers do not manage users or create, delete, or administer projects. Option D is also incorrect because the EDGE Auditor is an independent third-party verifier working under a certification body; the auditor does not serve as the project administrator inside the client's EDGE project workspace. The correct statement is therefore that a Project Editor is typically from the design team and can edit project details and documentation.
NEW QUESTION # 31
The COP of the water-cooled chiller is 6, and the cooling thermal load is 3516 W. What is the power rating of the chiller?
- A. 3522 W
- B. 3510 W
- C. 586 W
- D. 21096 W
Answer: C
Explanation:
The Coefficient of Performance (COP) is used in EDGE to calculate the electrical power input required for a given thermal output of a chiller. The EDGE Methodology Report defines COP as: "COP is the ratio of thermal output to electrical input, expressed as COP = Thermal Output / Electrical Input. To find the electrical input (power rating), rearrange the formula: Electrical Input = Thermal Output / COP" (EDGE Methodology Report Version 2.0, Section 5.1: Energy Efficiency Metrics). Given the COP of the water-cooled chiller as 6 and the cooling thermal load (thermal output) as 3516 W, the power rating is calculated as follows: Electrical Input = 3516 W / 6 = 586 W. Option A, 586 W, matches this calculation. Option B (3510 W) is incorrect, as it is slightly less than the thermal output, implying an unrealistic COP near 1. Option C (3522 W) is slightly above the thermal output, also incorrect. Option D (21096 W) is the result of multiplying the thermal output by the COP (3516 × 6), which is the inverse of the correct calculation. The EDGE User Guide confirms: "For a chiller with a COP of 6, the electrical input is one-sixth of the thermal output, ensuring energy efficiency is accurately assessed" (EDGE User Guide, Section 4.2: Energy Efficiency Measures). Thus, the power rating is
586 W (Option A).

NEW QUESTION # 32
In the EDGE certification system, who is responsible for the entire project including providing project documentation, access to the site, and the payment of audit and certification fees?
- A. Project Owner
- B. EDGE Certification Provider
- C. EDGE Auditor
- D. EDGE Expert
Answer: A
Explanation:
The EDGE certification process assigns clear responsibilities to various stakeholders to ensure a smooth and accountable process. The EDGE Certification Protocol defines the role of the ProjectOwner (also referred to as the EDGE Client): "The Project Owner, as the EDGE Client, is responsible for the entire project within the EDGE certification system. This includes providing all necessary project documentation (e.g., drawings, specifications, and self-assessments), ensuring access to the site for audits, and paying the audit and certification fees as required by the Certification Provider" (EDGE Certification Protocol, Section 2.1: Roles and Responsibilities). Option C, Project Owner, directly aligns with this comprehensive responsibility. Option A (EDGE Expert) is incorrect, as the Expert's role is advisory: "The EDGE Expert provides consultancy services, assisting with documentation and measure selection, but the ultimate responsibility for submission and payment lies with the Project Owner" (EDGE Expert and Auditor Protocols, Section 2.1: Roles of EDGE Expert). Option B (EDGE Auditor) is also incorrect, as the Auditor's role is to verify compliance, not manage the project: "The EDGE Auditor conducts independent audits and is not responsible for project management, documentation provision, or fee payments" (EDGE Expert and Auditor Protocols, Section 2.2: Roles of EDGE Auditor). Option D (EDGE Certification Provider) is responsible for issuing certificates and overseeing the process, not managing the project: "The EDGE Certification Provider, such as GBCI, reviews the Auditor's recommendation and issues certificates, but does not manage the project or pay fees" (EDGE Certification Protocol, Section 3.3: Certification Decision). The EDGE User Guide further reinforces this:
"The Project Owner must coordinate all aspects of the certification process, ensuring documentation is complete, site access is granted for post-construction audits, and all fees are paid to the Certification Provider in a timely manner" (EDGE User Guide, Section 6.1: Project Preparation). This holistic responsibility makes the Project Owner (Option C) the correct answer.
Reference:EDGE Certification Protocol, Section 2.1: Roles and Responsibilities, Section 3.3: Certification Decision; EDGE Expert and Auditor Protocols, Section 2.1: Roles of EDGE Expert, Section 2.2: Roles of EDGE Auditor; EDGE User Guide Version 2.1, Section 6.1: Project Preparation.
NEW QUESTION # 33
Within the EDGE methodology, recycled water or rainwater harvested on site is deducted from the building's Improved Case water consumption and is reported as:
- A. Potable water
- B. Wastewater
- C. Water savings
- D. Water usage
Answer: C
Explanation:
The EDGE methodology quantifies the impact of water efficiency measures like rainwater harvesting and recycled water by comparing the Improved Case to the Base Case. The EDGE Methodology Report states:
"Recycled water or rainwater harvested on site reduces the building's potable water demand in the Improved Case. This reduction is deducted from the Improved Case water consumption and reported as water savings in the EDGE software, reflecting the volume of potable water no longer required due to the measure" (EDGE Methodology Report Version 2.0, Section 4.2: Water Savings Calculations). Option B, water savings, accurately reflects this reporting method, as the software highlights the reduction in potable water use as a saving. Option A (water usage) is incorrect, as this term refers to the total consumption, not the reduction:
"Water usage in EDGE refers to the total volume consumed, not the savings achieved" (EDGE User Guide, Glossary). Option C (wastewater) is unrelated, as it refers to water output, not savings: "Wastewater is water discharged from the building, not a savings metric" (EDGE User Guide, Glossary). Option D (potable water) is also incorrect, as the measure reduces potable water use, but the reported metric is the saving, not the potable water itself: "Potable water demand is an input, while savings are the output" (EDGE User Guide, Section 5.2: Water Efficiency Measures). Thus, the correct reporting is water savings (Option B).
Reference:EDGE Methodology Report Version 2.0, Section 4.2: Water Savings Calculations; EDGE User Guide Version 2.1, Section 5.2: Water Efficiency Measures, Glossary.
NEW QUESTION # 34
Utility cost savings are calculated based on reduction in total:
- A. Energy and water consumption from the supply grid.
- B. Generator fuel and water consumption.
- C. Electricity and water consumption.
- D. Building energy and water consumption.
Answer: A
Explanation:
Utility cost savings in EDGE are calculated based on reductions in resource consumption sourced from the supply grid, as these are the costs directly borne by the building owner. The EDGE User Guide explains:
"Utility cost savings in EDGE are calculated based on the reduction in energy and water consumption from the supply grid, using local tariffs for electricity and water to convert resource savings into financial savings" (EDGE User Guide, Section 2.4: Interpreting EDGE Results). Option D, energy and water consumption from the supply grid, aligns with this definition, focusing on grid-supplied resources. Option A (electricity and water consumption) is partially correct but lacks specificity about the source: "Electricity and water must be grid-supplied to be included in utility cost savings; onsite generation is excluded" (EDGE Methodology Report Version 2.0, Section 4.4: Cost Savings Calculations). Option B (generator fuel and water consumption) is incorrect, as generator fuel is not part of utility cost savings: "Generator fuel costs are not included in utility savings, as EDGE focuses on grid-supplied utilities" (EDGE User Guide, Section 2.4:
Interpreting EDGE Results). Option C (building energy and water consumption) is too broad, including onsite sources: "Building consumption includes all sources, but utility savings are grid-specific" (EDGE Methodology Report Version 2.0, Section 4.4: Cost Savings Calculations). Thus, energy and water from the supply grid (Option D) is the correct basis for utility cost savings.
Reference: EDGE User Guide Version 2.1, Section 2.4: Interpreting EDGE Results; EDGE Methodology Report Version 2.0, Section 4.4: Cost Savings Calculations.
NEW QUESTION # 35
Which information about local climate is used for EDGE calculations?
- A. Weekly averages for outdoor minimum and maximum temperatures, wind velocity, outdoor humidity, and solar radiation
- B. Annual averages for outdoor minimum and maximum temperatures, wind velocity, outdoor humidity, and solar radiation
- C. Monthly averages for outdoor minimum and maximum temperatures, wind velocity, outdoor humidity, and solar radiation
- D. Hourly averages for outdoor minimum and maximum temperatures, wind velocity, outdoor humidity, and solar radiation
Answer: C
Explanation:
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.
NEW QUESTION # 36
To claim efficiency measure Insulation for Cold Storage Envelope, which of the following documents is required as evidence at the preliminary certification stage?
- A. Drawing(s) showing the U-value specification of the cold storage envelope
- B. Purchase receipts showing the U-value specification of the cold storage envelope
- C. Calculations of Coefficient of Performance (COP)
- D. Manufacturer's data sheets for the HVAC system
Answer: A
Explanation:
The preliminary certification stage requires specific documentation to verify the implementation of efficiency measures like Insulation for Cold Storage Envelope. The EDGE Certification Protocol outlines the evidence requirements: "For measures involving insulation, such as Insulation for Cold Storage Envelope, the Client must provide drawings at the preliminary certification stage that specify the U-value of the installed insulation to demonstrate compliance with the measure's requirements. The U-value must be lower than the Base Case to qualify for savings" (EDGE Certification Protocol, Section 3.2: Audit Requirements). Option C, drawings showing the U-value specification of the cold storage envelope, directly aligns with this requirement. Option A (calculations of Coefficient of Performance) is irrelevant, as COP applies to HVAC systems, not insulation:
"COP is used for chillers, not insulation measures" (EDGE User Guide, Section 4.2: Energy Efficiency Measures). Option B (manufacturer's data sheets for the HVAC system) is also unrelated, as the measure focuses on the envelope, not HVAC: "HVAC documentation is not required for insulation measures" (EDGE Certification Protocol, Section 3.2: Audit Requirements). Option D (purchase receipts showing the U-value) is more relevant at the post-construction stage: "Purchase receipts are typically required at the post-construction stage to confirm installation, while drawings suffice for design-stage verification" (EDGE Certification Protocol, Section 3.4: Post-Construction Requirements). Thus, drawings with U-value specifications (Option C) are required at preliminary certification.
Reference:EDGE Certification Protocol, Section 3.2: Audit Requirements, Section 3.4: Post-Construction Requirements; EDGE User Guide Version 2.1, Section 4.2: Energy Efficiency Measures.
NEW QUESTION # 37
How many years of experience in related fields are required for applicants without a construction-related higher qualification to become an EDGE Expert?
- A. At least 3 years
- B. At least 5 years
- C. At least 2 years
- D. At least 1 year
Answer: A
Explanation:
The eligibility criteria for becoming an EDGE Expert are designed to ensure candidates have sufficient background to advise on green building projects. The EDGE Expert and Auditor Protocols specify the requirements for candidates without a construction-related higher qualification: "Applicants without a higher education qualification in a construction-related field (e.g., architecture, engineering) must have a higher education qualification in any field plus at least three years of experience in the construction industry as a skilled professional or tradesperson to qualify for EDGE Expert training and certification" (EDGE Expert and Auditor Protocols, Section 3.1: Eligibility Criteria). Option C, at least 3 years, directly matches this requirement. Option A (at least 1 year) and Option B (at least 2 years) are insufficient, as they fall below the minimum threshold: "Less than three years of experience does not meet the eligibility criteria for candidates without a construction-related degree, as this duration ensures adequate practical knowledge of building design and construction processes" (EDGE Expert and Auditor Protocols, Section 3.1: Eligibility Criteria).
Option D (at least 5 years) exceeds the minimum requirement, which is not necessary: "While additional experience is beneficial, the minimum requirement for EDGE Expert eligibility is three years for non- construction degree holders" (EDGE User Guide, Section 6.4: Working with EDGE Experts). The EDGE Certification Protocol also notes: "The three-year experience requirement for non-construction graduates ensures that EDGE Experts have sufficient industry exposure to provide meaningful consultancy, balancing accessibility with competence" (EDGE Certification Protocol, Section 1.3: Program Structure). Additionally, the EDGE User Guide clarifies: "Candidates with a construction-related degree are exempt from the experience requirement, but those without such a degree must demonstrate at least three years of relevant experience to qualify for the EDGE Expert exam" (EDGE User Guide, Section 6.4: Working with EDGE Experts). Therefore, at least 3 years of experience (Option C) is required for applicantswithout a construction- related higher qualification.
Reference:EDGE Expert and Auditor Protocols, Section 3.1: Eligibility Criteria; EDGE Certification Protocol, Section 1.3: Program Structure; EDGE User Guide Version 2.1, Section 6.4: Working with EDGE Experts.
NEW QUESTION # 38
Which are the certification levels within the EDGE certification system?
- A. EDGE Certified, EDGE Advanced, and EDGE Zero Energy
- B. EDGE Certified, EDGE Silver, and EDGE Gold
- C. EDGE Certified, EDGE Advanced, and EDGE Zero Carbon
- D. EDGE Silver, EDGE Gold, and EDGE Platinum
Answer: C
Explanation:
The CBCI EDGE curriculum explains that the EDGE system uses a tiered structure that starts with resource- efficiency certification and can progress to a net-carbon outcome. The foundational level is EDGE Certified, which is achieved when a project demonstrates at least 20 percent savings in energy, water, and embodied energy in materials compared with the baseline. Above this is EDGE Advanced, which retains the same minimum 20 percent requirements for water and materials while requiring a higher performance threshold for energy, meaning at least 40 percent energy savings.
Beyond these two efficiency tiers, the system includes EDGE Zero Carbon, which builds on EDGE Certified or EDGE Advanced by addressing the project's carbon footprint through a combination of high energy efficiency, on-site or off-site renewable energy to reduce operational emissions, and carbon offsets for remaining operational emissions to reach net zero operational carbon.
The options that mention Silver, Gold, and Platinum reflect other rating systems, not EDGE. EDGE also does not use "EDGE Zero Energy" as the certification level name in the core tier list presented in the curriculum.
Therefore, the correct set of certification levels is EDGE Certified, EDGE Advanced, and EDGE Zero Carbon.
NEW QUESTION # 39
Which of the following hot water technologies is from a renewable source?
- A. Solar hot water collectors
- B. Ground source heat pump
- C. Preheating water using waste heat from the generator
- D. High efficiency boiler for water heating
Answer: A
Explanation:
EDGE recognizes renewable energy sources for their contribution to reducing carbon emissions in hot water production. The EDGE User Guide defines renewable hot water technologies: "Solar hot water collectors are considered a renewable source in EDGE, as they directly use solar energy to heat water, reducing reliance on fossil fuel-based energy" (EDGE User Guide, Section 4.2: Energy Efficiency Measures). Option B, solar hot water collectors, matches this description as it harnesses solar energy, a renewable resource. Option A (ground source heat pump) uses electricity to transfer heat from the ground, which is efficient but not renewable unless the electricity is from a renewable source: "Ground source heat pumps are efficient but rely on electrical input, not classified as a renewable source in EDGE" (EDGE Methodology Report Version 2.0, Section 5.1: Energy Efficiency Metrics). Option C (high efficiency boiler) typically uses gas or electricity, not a renewable source: "Boilers, even high-efficiency ones, are not renewable as they burn fuel or use grid electricity" (EDGE User Guide, Section 4.2: Energy Efficiency Measures). Option D (preheating water using waste heat from the generator) is a heat recovery method, not a renewable source: "Waste heat recovery improves efficiency but is not considered a renewable energy source in EDGE" (EDGE Methodology Report Version 2.0, Section 5.3: Energy Measures). Thus, solar hot water collectors (Option B) is the renewable source technology.
Reference:EDGE User Guide Version 2.1, Section 4.2: Energy Efficiency Measures; EDGE Methodology Report Version 2.0, Section 5.1: Energy Efficiency Metrics, Section 5.3: Energy Measures.
NEW QUESTION # 40
A hotel developer is planning a project. The specifications are based on corporate design standards for water fittings, lighting, heating, and air-conditioning. The EDGE Base Case will:
- A. Not be suitable for certification of this project.
- B. Use the local typical building practices or code.
- C. Be adapted to accommodate corporate specifications.
- D. Be verified on a case-by-case basis for the hotel chain.
Answer: B
Explanation:
The EDGE software's Base Case is a standardized benchmark that does not adjust to project-specific corporate standards but reflects local norms. The EDGE User Guide states: "The Base Case in EDGE software is automatically generated based on local typical building practices and, where applicable, national building codes for the selected typology and location. It does not incorporate project-specific corporate standards or custom specifications, ensuring a consistent baseline for comparison" (EDGE User Guide, Section 2.3: Using the EDGE App). In this scenario, the hotel developer's corporate design standards for water fittings, lighting, heating, and air-conditioning are specific to the project, but the EDGE Base Case will still use local typical practices or codes (Option C). Option A is incorrect, as the project can still be certified using the standard Base Case. Option B is wrong because the Base Case does not adapt to corporate specifications. Option D is also incorrect, as the Base Case is not verified on a case-by-case basis for specific hotel chains but is standardized for the region and typology.
Reference:EDGE User Guide Version 2.1, Section 2.3: Using the EDGE App; EDGE Methodology Report Version 2.0, Section 3.1: Base Case Determination.
NEW QUESTION # 41
Which of the following measures require testing by the EDGE Auditor at the site audit?
- A. WEM03 - Low-flow Faucets for Bathrooms
- B. EEM07 - Green Roof
- C. WEM16 - Condensate Water Recovery
- D. WEM15 - Waste Water Treatment and Recycling System
Answer: A
Explanation:
According to the CBCI EDGE certification procedures, certain measures require physical verification and performance testing during the site audit to confirm that installed systems match the design-stage commitments entered in the EDGE software. Low-flow faucets for bathrooms fall into this category because their compliance depends on measurable flow rates. During the audit, the EDGE Auditor may use flow- measuring devices to test fixture discharge rates and verify that they meet the specified liters per minute used in the improved case calculations. This ensures that projected water savings are genuinely achieved in practice.
In contrast, measures such as a green roof are typically verified visually and through documentation such as drawings and material specifications rather than performance testing. Condensate water recovery and wastewater treatment systems are usually confirmed through installed system inspection, capacity checks, and documentation review, but not necessarily through direct flow-rate testing at each fixture point like low-flow faucets. The curriculum emphasizes that fixtures with defined performance parameters, such as flow rates, are subject to on-site testing to maintain the integrity and credibility of EDGE water savings claims.
NEW QUESTION # 42
For existing buildings, which of the following elements would increase the embodied carbon in the EDGE assessment?
- A. New materials included in the retrofit
- B. Existing roof construction
- C. External shading devices
- D. New mechanical systems included in the retrofit
Answer: A
Explanation:
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.
NEW QUESTION # 43
VRV / VRF System is best used for:
- A. Multizone space
- B. Meeting space
- C. Single zone space
- D. Single zone office space
Answer: A
Explanation:
Variable Refrigerant Volume (VRV) or Variable Refrigerant Flow (VRF) systems are evaluated in EDGE for their energy efficiency in HVAC applications. The EDGE User Guide explains their application: "VRV/VRF systems are best suited for multizone spaces, as they can simultaneously heat and cool different zones by varying the refrigerant flow, making them ideal for buildings with diverse thermal loads, such as hotels, offices, or hospitals with multiple rooms" (EDGE User Guide, Section 4.2: Energy Efficiency Measures).
Option C, multizone space, aligns with this description, as VRV/VRF systems excel in managing varied temperature needs across multiple zones. Option A (single zone space) and Option B (single zone office space) are incorrect, as VRV/VRF systems are less efficient for single zones: "For single zone spaces, simpler systems like split units are more appropriate, as VRV/VRF systems are designed for multizone control" (EDGE Methodology Report Version 2.0, Section 5.1: Energy Efficiency Metrics). Option D (meeting space) is too specific and typically a single zone, not leveraging VRV/VRF's multizone capability: "Meeting spaces are often single zones, where VRV/VRF systems may be oversized" (EDGE User Guide, Section 4.2: Energy Efficiency Measures). Thus, VRV/VRF systems are best used for multizone spaces (Option C).
Reference: EDGE User Guide Version 2.1, Section 4.2: Energy Efficiency Measures; EDGE Methodology Report Version 2.0, Section 5.1: Energy Efficiency Metrics.
NEW QUESTION # 44
EDGE was created for new buildings to promote:
- A. Few exemplary high-performance buildings.
- B. Highly accurate prediction of resource consumption.
- C. Simple and scalable platform for green buildings.
- D. Revenue for green building champions.
Answer: C
Explanation:
The purpose of EDGE, as defined by the International Finance Corporation (IFC), is to make green building accessible and scalable, particularly in emerging markets. The EDGE User Guide states: "EDGE was created by IFC to promote a simple and scalable platform for green buildings, enabling developers to achieve resource efficiency in new constructions through a user-friendly tool that focuses on energy, water, and materials savings" (EDGE User Guide, Section 1.1: Introduction to EDGE). Option C, a simple and scalable platform for green buildings, directly aligns with this mission. Option A (revenue for green building champions) is incorrect, as EDGE's goal is not financial gain for individuals but broader market transformation: "EDGE aims to transform the building sector, not to generate revenue for specific stakeholders" (EDGE Certification Protocol, Section 1.1: Overview). Option B (few exemplary high- performance buildings) contradicts EDGE's scalability focus: "EDGE is not about creating a few high- performance buildings but enabling widespread adoption of green practices" (EDGE User Guide, Section 1.1:
Introduction to EDGE). Option D (highly accurate prediction of resource consumption) is also incorrect, as EDGE prioritizes simplicity over precision: "EDGE uses simplified calculations for resource consumption, not highly accurate predictions, to ensure accessibility" (EDGE Methodology Report Version 2.0, Section 2.1:
Calculation Approach). Thus, EDGE promotes a simple and scalable platform (OptionC).
Reference:EDGE User Guide Version 2.1, Section 1.1: Introduction to EDGE; EDGE Certification Protocol, Section 1.1: Overview; EDGE Methodology Report Version 2.0, Section 2.1: Calculation Approach.
NEW QUESTION # 45
A project certificate that meets the EDGE Zero Carbon criteria fully on-site providing generation of on-site renewable electricity, will expire every
- A. four years.
- B. two years.
- C. five years.
- D. three years.
Answer: A
Explanation:
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.
NEW QUESTION # 46
What is the eligibility requirement to attend an EDGE Expert training?
- A. Three years of experience working as a skilled professional or tradesperson in the construction industry
- B. At least a bachelor's degree qualification in a construction industry related field
- C. At least a bachelor's degree qualification in any field
- D. No prerequisite regarding qualifications
Answer: D
Explanation:
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.
NEW QUESTION # 47
How often is the EDGE Baseline reviewed, including the geographic coverage of EDGE?
- A. 1-2 years
- B. 8-10 years
- C. 3-5 years
- D. 6-8 years
Answer: C
Explanation:
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.
NEW QUESTION # 48
In the EDGE software, which of the following does NOT produce grey water?
- A. Bath tub
- B. Hand wash basin
- C. Shower
- D. Water closet WC
Answer: D
Explanation:
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.
NEW QUESTION # 49
What or who determines the baseline assumptions in EDGE?
- A. EDGE software users
- B. Market survey of typical construction practices
- C. EDGE Auditors
- D. Market survey of best construction practices
Answer: B
Explanation:
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).
Reference:EDGE Methodology Report Version 2.0, Section 3.1: Base Case Determination; EDGE User Guide Version 2.1, Section 2.3: Using the EDGE App.
NEW QUESTION # 50
In the EDGE software, which of the following methodologies is used for energy calculations?
- A. Look-up tables of benchmarks Rules of thumb
- B. Quasi-steady-state model
- C. Dynamic Simulation model
- D. Actual energy data from field survey
Answer: B
Explanation:
The EDGE software uses a quasi-steady-state calculation methodology for estimating building energy performance. This approach simplifies energy modeling by calculating heat gains and losses based on steady- state assumptions over defined time intervals, rather than performing detailed hour-by-hour simulations. The quasi-steady-state method allows EDGE to provide rapid and consistent energy performance assessments while maintaining sufficient technical accuracy for early design decision-making.
Unlike dynamic simulation models, which require complex input data, specialized software, and detailed operational schedules, the EDGE methodology is designed to be accessible and user-friendly for architects, engineers, and developers in emerging markets. It evaluates energy performance by comparing a baseline case, derived from local climate data and standard building practices, with an improved case reflecting selected energy efficiency measures.
Actual field survey energy data is not used because EDGE is primarily a design-stage predictive tool rather than a post-occupancy measurement system. Similarly, the calculations are not based solely on simplified look-up tables or rules of thumb. The quasi-steady-state model strikes a balance between technical rigor and usability, which is a core principle emphasized in the CBCI EDGE curriculum.
NEW QUESTION # 51
What will reduce the hot water demand in a hotel building?
- A. Low-flow shower heads
- B. Solar photovoltaics (PVs)
- C. Heat pumps for hot water
- D. Solar water heating
Answer: A,C,D
Explanation:
Reducing hot water demand in hotels is a key green building strategy in EDGE, focusing on both supply-side and demand-side measures. The EDGE User Guide details measures that reduce hot water demand: "Hot water demand in hotels can be reduced through supply-side measures like solar water heating and heat pumps for hot water, which decrease the energy needed to heat water, and demand-side measures like low-flow shower heads, which reduce the volume of hot water used" (EDGE User Guide, Section 5.2: Water Efficiency Measures, Section 4.2: Energy Efficiency Measures). Option B (solar water heating) reduces hot water demand by providing a renewable heat source, thus lowering energy use for heating. Option C (low-flow shower heads) directly reduces the volume of hot water used by limiting flow rates: "Low-flow shower heads can reduce hot water consumption by up to 30% in hotels" (EDGE Methodology Report Version 2.0, Section
4.2: Water Savings Calculations). Option D (heat pumps for hot water) reduces energy demand for heating water by using a more efficient system: "Heat pumps for hot water have a high COP, reducing the energy required to meet hot water demand" (EDGE User Guide, Section 4.2: Energy Efficiency Measures). Option A (solar photovoltaics) generates electricity, not hot water, and does not directly reduce hot water demand:
"Solar PVs contribute to electricity generation, not hot water production" (EDGE Methodology Report Version 2.0, Section 5.3: Energy Measures). Thus, Options B, C, and D all reduce hot water demand in a hotel.
Reference:EDGE User Guide Version 2.1, Section 5.2: Water Efficiency Measures, Section 4.2: Energy Efficiency Measures; EDGE Methodology Report Version 2.0, Section 4.2: Water Savings Calculations, Section 5.3: Energy Measures.
