What will reduce the hot water demand in a hotel building?

• A. Solar photovoltaics (PVs)
• B. Low-flow shower heads
• C. Heat pumps for hot water
• D. Solar water heating

正解：B、C、D

解説：
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.

質問 # 28
In order for a project to complete the design certification stage requirements, the EDGE Client must do which of the following?

• A. Review and sign an agreement with a local or global partner to provide EDGE certification services.
• B. Access the EDGE software and begin and complete a full self-assessment of the building.
• C. Internally review the EDGE measures with their design team and third-party consultant.
• D. Provide the EDGE Auditor access to the self-assessment and all supporting documentation.

正解：D

解説：
The design certification stage (Preliminary Certification) in EDGE requires specific actions from the Client to ensure the project can be audited and certified. The EDGE Certification Protocol outlines the process: "To complete the design certification stage, the EDGE Client must provide the EDGE Auditor with access to the completed self-assessment in the EDGE software, along with all supporting documentation, such as drawings, specifications, and calculations, to verify the selected measures" (EDGE Certification Protocol, Section 3.1:
Certification Process). Option C, provide the EDGE Auditor access to the self-assessment and all supporting documentation, matches this requirement. Option A (internally review the EDGE measures) is a preparatory step, not a certification requirement: "Internal reviews are recommended but not mandated for certification" (EDGE User Guide, Section 6.1: Project Preparation). Option B (access the EDGE software and complete a self-assessment) is a prerequisite to the audit, not the final step for design certification: "The self-assessment must be completed before the audit, but certification requires submission to the Auditor" (EDGE Certification Protocol, Section 3.1: Certification Process). Option D (sign an agreement with a certification partner) is incorrect, as this is typically handled during project registration, not design certification: "Agreements with Certification Providers are signed prior to registration, not at the design stage" (EDGE Certification Protocol, Section 2.1: Registration). Thus, providing the Auditor access (Option C) is the required action.
Reference:EDGE Certification Protocol, Section 3.1: Certification Process, Section 2.1: Registration; EDGE User Guide Version 2.1, Section 6.1: Project Preparation.

質問 # 29
What is the minimum percentage of efficient lightbulbs that must be installed to claim the measure EEM22 - Efficient Lighting for Internal Areas?

• A. 100%
• B. 70%
• C. 90%
• D. 80%

正解：C

解説：
The EDGE measure EEM22 - Efficient Lighting for Internal Areas focuses on reducing energy consumption through the use of efficient lighting. The EDGE User Guide specifies the requirements for this measure: "To claim EEM22 - Efficient Lighting for Internal Areas, at least 90% of the lamps in internal areas must be energy-efficient, such as LED or CFL, with a luminous efficacy of at least 80 lumens per watt. This threshold ensures significant energy savings while allowing for minimal exceptions in specific areas" (EDGE User Guide, Section 4.4: Lighting Efficiency Measures). Option C, 90%, directly matches this requirement. Option A (70%) and Option B (80%) are below the threshold, thus not qualifying for the measure. Option D (100%) exceeds the minimum requirement, but EDGE allows for flexibility with a 90% threshold to accommodate practical constraints: "A 90% requirement balances practicality with energy savings, recognizing that some areas may require specialized lighting" (EDGE Methodology Report Version 2.0, Section 5.4: Lighting Calculations). Therefore, the minimum percentage to claim EEM22 is 90% (Option C).
Reference:EDGE User Guide Version 2.1, Section 4.4: Lighting Efficiency Measures; EDGE Methodology Report Version 2.0, Section 5.4: Lighting Calculations.

質問 # 30
Which of the following protocols should be followed when the project city is not listed in the EDGE App?

• A. Choose the capital city to the project location and edit the climate data if necessary.
• B. Write to EDGE Certifier to request the city to be included and wait for the application to be updated.
• C. Select any city in the same climate zone around the world and use that to certify the project.
• D. Choose the closest city to the project location and edit the climate data if necessary.

正解：D

解説：
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).

2.0, Section 3.2: Climate Data Inputs.

質問 # 31
Coefficient of Performance (COP) of the electrical chiller is defined as:

• A. Electrical output / electrical input.
• B. Electrical input / thermal output.
• C. Thermal output / electrical input.
• D. Thermal output / thermal input.

正解：C

解説：
The Coefficient of Performance (COP) is a critical metric in EDGE for assessing the energy efficiency of chillers, a common green building design element. The EDGE Methodology Report defines COP for electrical chillers: "The Coefficient of Performance (COP) of an electrical chiller is defined as the ratio of thermal output (cooling provided, measured in kW) to electrical input (power consumed, measured in kW). A higher COP indicates greater efficiency, as more cooling is produced per unit of electricity" (EDGE Methodology Report Version 2.0, Section 5.1: Energy Efficiency Metrics). Option B, thermal output / electrical input, matches this definition directly. Option A (thermal output / thermal input) is incorrect, as it applies to heat- driven systems like absorption chillers, not electrical ones. Option C (electrical input / thermal output) inverts the ratio, representing the inverse of COP. Option D (electrical output / electrical input) is irrelevant, as chillers produce thermal output, not electrical output. The EDGE User Guide reinforces this: "For air-cooled and water-cooled chillers, COP is calculated as thermal output divided by electrical input to evaluate energy efficiency" (EDGE User Guide, Section 4.2: Energy Efficiency Measures).
Reference:EDGE Methodology Report Version 2.0, Section 5.1: Energy Efficiency Metrics; EDGE User Guide Version 2.1, Section 4.2: Energy Efficiency Measures.

質問 # 32
Which of the following can deliver the highest efficiency in fans and pumps?

• A. Two speed drive
• B. Variable speed drive
• C. Constant speed drive
• D. Single speed drive

正解：B

解説：
Efficiency in fans and pumps is a critical aspect of green building design in EDGE, particularly for reducing energy consumption in HVAC systems. The EDGE User Guide provides detailed guidance on efficiency measures for mechanical systems: "Variable speed drives (VSDs) deliver the highest efficiency in fans and pumps by adjusting the motor speed to match the actual demand, significantly reducing energy consumption compared to fixed-speed systems. VSDs can achieve energy savings of up to 30-50% in HVAC applications by avoiding the constant operation at full speed typical of single or constant speed drives" (EDGE User Guide, Section 4.2: Energy Efficiency Measures). Option D, variable speed drive, aligns with this description as the most efficient option. Option A (two speed drive) offers some efficiency by allowing two operating speeds, but it is less flexible than VSDs: "Two speed drives provide limited efficiency gains, as they cannot continuously adjust to varying loads, unlike variable speed drives" (EDGE Methodology Report Version 2.0, Section 5.1: Energy Efficiency Metrics). Option B (single speed drive) and Option C (constant speed drive) are essentially the same in this context, operating at a fixed speed regardless of demand, leading to energy waste: "Single speed or constant speed drives run at a fixed rate, resulting in higher energy consumption compared to variable speed drives, which modulate speed based on need" (EDGE User Guide, Section 4.2:
Energy Efficiency Measures). The EDGE Methodology Report further elaborates: "Variable speed drives are the most efficient option for fans and pumps in EDGE, as they minimize energy use by matching output to demand, unlike two speed or constant speed drives, which operate inefficiently under partial loads" (EDGE Methodology Report Version 2.0, Section 5.1: Energy Efficiency Metrics). This makes variable speed drives (Option D) the clear choice for delivering the highest efficiency in fans and pumps.
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.

質問 # 33
Is it possible to be both the EDGE Expert and Auditor on a project?

• A. Yes, but only in the case that there are no other EDGE Auditors available for the project.
• B. No, even if EDGE Certifier agrees to special terms to have no conflict of interest.
• C. Yes, they can be both an EDGE Auditor and EDGE Expert in all cases.
• D. No, an EDGE Expert cannot be the EDGE Auditor on the same project.

正解：D

解説：
The EDGE framework strictly enforces separation of roles to maintain integrity and avoid conflicts of interest during the certification process. The EDGE Expert and Auditor Protocols explicitly address this issue: "An individual cannot serve as both the EDGE Expert and EDGE Auditor on the same project. This separation ensures independence in the audit process, as the Expert's role as a consultant advising the project team could bias the Auditor's objective assessment of the project's compliance with EDGE standards" (EDGE Expert and Auditor Protocols, Section 2.3: Conflict of Interest). Option A, no, an EDGE Expert cannot be the EDGE Auditor on the same project, directly reflects this rule. Option B (no, even if the Certifier agrees to special terms) adds an unnecessary condition, as the protocols do not allow exceptions: "No exceptions are permitted for an individualto serve in both roles on the same project, regardless of agreements or special terms" (EDGE Expert and Auditor Protocols, Section 2.3: Conflict of Interest). Option C (yes, in all cases) is incorrect, as it contradicts the conflict-of-interest rules: "Allowing dual roles in all cases would undermine the impartiality required for certification" (EDGE Certification Protocol, Section 3.1: Certification Process). Option D (yes, if no other Auditors are available) is also incorrect, as availability does not override the conflict-of-interest prohibition: "Even if no other Auditors are available, the roles must remain separate; the Client must find a different Auditor or delay the audit" (EDGE Expert and Auditor Protocols, Section 4.1: Audit Process). The EDGE User Guide reinforces this principle: "The separation of Expert and Auditor roles ensures a fair and unbiased certification process, protecting the credibility of EDGE certification" (EDGE User Guide, Section
6.4: Working with EDGE Experts). Thus, it is not possible to be both (Option A).
Reference:EDGE Expert and Auditor Protocols, Section 2.3: Conflict of Interest, Section 4.1: Audit Process; EDGE Certification Protocol, Section 3.1: Certification Process; EDGE User Guide Version 2.1, Section 6.4:
Working with EDGE Experts.

質問 # 34
The Client has sent a copy of the local occupancy permit for a project being audited. This permit:

• A. Does not replace the need to audit all EDGE measures.
• B. Replaces the need to audit EDGE Materials measures.
• C. Does not replace the need for desktop studies.
• D. Replaces the need to audit all EDGE measures.

正解：A

解説：
An occupancy permit indicates that a building meets local regulatory requirements for occupancy,but it does not address the specific green building measures required for EDGE certification. The EDGE Certification Protocol clearly outlines the role of such permits in the audit process: "A local occupancy permit provided by the Client confirms that the building complies with local building codes and is ready for use. However, it does not replace the need to audit all EDGE measures, as EDGE certification requires verification of specific energy, water, and materials efficiency measures that are not typically covered by local permits" (EDGE Certification Protocol, Section 3.4: Post-Construction Requirements). Option A, does not replace the need to audit all EDGE measures, directly aligns with this guidance, as the Auditor must still verify each claimed measure (e.g., insulation, low-flow fixtures, fly ash concrete) against EDGE standards. Option B (replaces the need to audit all EDGE measures) is incorrect, as the permit does not address EDGE-specific requirements:
"Local permits do not verify EDGE measures like energy savings or embodied energy reductions, so a full audit is still required" (EDGE Expert and Auditor Protocols, Section 4.4: Site Audit Procedures). Option C (does not replace the need for desktop studies) is partially correct but less comprehensive, as desktop studies are only one part of the audit process: "Desktop studies are part of the audit, but the occupancy permit does not exempt any aspect of the EDGE audit, including site visits and measure verification" (EDGE Certification Protocol, Section 3.2: Audit Requirements). Option D (replaces the need to audit EDGE Materials measures) is also incorrect, as materials measures (e.g., use of fly ash concrete) require specific evidence like manufacturer's data sheets, not covered by an occupancy permit: "Materials measures require detailed documentation of embodied energy reductions, which local permits do not address" (EDGE User Guide, Section 7.2: Materials Efficiency Measures). The EDGE User Guide further reinforces: "The Auditor must verify all EDGE measures through appropriate documentation and site visits, regardless of local permits, to ensure compliance with the EDGE standard" (EDGE User Guide, Section 6.3: Post-Construction Certification). Thus, the occupancy permit does not replace the need to audit all EDGE measures (Option A).
Reference:EDGE Certification Protocol, Section 3.4: Post-Construction Requirements, Section 3.2: Audit Requirements; EDGE Expert and Auditor Protocols, Section 4.4: Site Audit Procedures; EDGE User Guide Version 2.1, Section 6.3: Post-Construction Certification, Section 7.2: Materials Efficiency Measures.

質問 # 35
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.

正解：A

解説：
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 Version2.0, 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.

質問 # 36
An EDGE Auditor is auditing a hospital design for Preliminary Certification. The EDGE Client has included photovoltaics as one of the energy measures resulting in an overall 21% saving in energy. The Auditor observes the photovoltaics are facing the wrong direction. What action should the Auditor take?

• A. Contact the design team directly and suggest a better orientation for the photovoltaics.
• B. Reject photovoltaics from the selected set of energy measures and notify the Client regarding the orientation.
• C. Assess the energy measures as they are presented to you, without changing the photovoltaic selection.
• D. Adjust the area of photovoltaic panels in the assessment to allow for reduction in energy output.

正解：C

解説：
The role of an EDGE Auditor is to verify the project's self-assessment as submitted, not to modify or redesign the project. The EDGE Expert and Auditor Protocols clearly define the Auditor's responsibilities: "During an audit, the EDGE Auditor must assess the energy measures as presented in the self-assessment, without altering the design or selections made by the Client. If discrepancies are found, such as incorrect orientation of photovoltaics, the Auditor should note the issue in the audit report but proceed with the assessment as submitted, allowing the Certification Provider to make the final decision" (EDGE Expert and Auditor Protocols, Section 4.1: Audit Process). Option C, assess the energy measures as they are presented without changing the photovoltaic selection, aligns with this protocol. Option A (contact the design team and suggest a better orientation) oversteps the Auditor's role, as they are not to provide design advice: "Auditors must not engage in design consultancy during an audit to avoid conflicts of interest" (EDGE Expert and Auditor Protocols, Section 2.3: Conflict of Interest). Option B (adjust the area of photovoltaic panels) involves modifying the assessment, which is prohibited: "Auditors cannot modify the Client's self-assessment; they must evaluate it as submitted" (EDGE Certification Protocol, Section 3.2: Audit Requirements). Option D (reject photovoltaics and notify the Client) is also incorrect, as Auditors do not have the authority to reject measures outright: "Rejection of measures is the responsibility of the Certification Provider, not the Auditor" (EDGE Certification Protocol, Section 3.3: CertificationDecision). Thus, the Auditor should assess as presented (Option C).
Reference:EDGE Expert and Auditor Protocols, Section 4.1: Audit Process, Section 2.3: Conflict of Interest; EDGE Certification Protocol, Section 3.2: Audit Requirements, Section 3.3: Certification Decision.

質問 # 37
Which of the following is an EDGE measure to reduce the embodied energy in materials?

• A. Fly ash concrete
• B. Low-flow shower heads
• C. External shading
• D. Occupancy sensors

正解：A

解説：
Embodied energy in materials is one of the three core pillars of the EDGE standard, focusing on reducing the environmental impact of construction materials. The EDGE User Guide lists measures that specifically target embodied energy: "To reduce embodied energy in materials, EDGE includes measures such as the use of fly ash concrete, which substitutes a portion of cement with fly ash, a byproduct of coal combustion, thereby lowering the embodied energy and carbon footprint of concrete production" (EDGE User Guide, Section 7.2:
Materials Efficiency Measures). Option B, fly ash concrete, directly aligns with this measure, as it reduces the need for high-energy cement production. Option A (external shading) impacts energy by reducing cooling loads but does not directly address embodied energy: "External shading reduces operational energy use but does not contribute to embodied energy savings unless the shading materials themselves are low-impact, which is not specified in EDGE" (EDGE User Guide, Section 3.5: Passive Design Strategies). Option C (occupancy sensors) is an energy efficiency measure for lighting, not materials: "Occupancy sensors reduce lighting energy use but have no direct impact on embodied energy in materials" (EDGE User Guide, Section
4.4: Lighting Efficiency Measures). Option D (low-flow shower heads) targets water efficiency, not materials:
"Low-flow shower heads reduce water consumption, but their embodied energy impact is minimal and not a focus of EDGE materials measures" (EDGE User Guide, Section 5.2: Water Efficiency Measures). The EDGE MethodologyReport further elaborates: "Fly ash concrete can reduce embodied energy by up to 20% compared to traditional concrete, making it a key measure in EDGE for materials efficiency, especially in high-volume applications like hospitals or hotels" (EDGE Methodology Report Version 2.0, Section 6.1:
Embodied Energy in Materials). Other materials measures in EDGE, such as using recycled steel or bamboo, are not listed among the options, making fly ash concrete (Option B) the correct choice for reducing embodied energy.
Reference:EDGE User Guide Version 2.1, Section 7.2: Materials Efficiency Measures, Section 3.5: Passive Design Strategies, Section 4.4: Lighting Efficiency Measures, Section 5.2: Water Efficiency Measures; EDGE Methodology Report Version 2.0, Section 6.1: Embodied Energy in Materials.

質問 # 38
A site audit must take place within how many months of the project's practical completion date?

• A. 36 months
• B. 18 months
• C. 24 months
• D. 12 months

正解：D

解説：
The timeline for conducting a site audit as part of the EDGE certification process is critical to ensure that the project's implementation aligns with the design-stage claims. The EDGE Certification Protocol specifies the timeframe for post-construction audits: "A site audit for EDGE certification must take place within 12 months of the project's practical completion date to verify that the green building measures have been implemented as claimed in the self-assessment. This ensures that the audit reflects the building's as-built condition while the project details are still current" (EDGE Certification Protocol, Section 3.4: Post-Construction Requirements).
Option A, 12 months, directly matches this requirement. Option B (18 months), Option C (24 months), and Option D (36 months) exceed the specified timeframe, which could lead to discrepancies due to changes in the building's condition or operation: "Conducting the site audit beyond 12 months may result in inaccuracies, as building systems or occupancy patterns may change, affecting the verification of measures" (EDGE Expert and Auditor Protocols, Section 4.4: Site Audit Procedures). The EDGE User Guide also supports this timeline: "To maintain the integrity of the certification process, the site audit should be scheduled within 12 months of practical completion, allowing the Auditor to assess the building in its initial operational state" (EDGE User Guide, Section 6.3: Post-Construction Certification). The 12-month limit ensures that the audit is timely and relevant, making Option A the correct answer. Additionally, the EDGE Certification Protocol notes: "Extensions beyond 12 months may be granted only in exceptional circumstances, subject toapproval by the Certification Provider, but this is not the standard requirement" (EDGE Certification Protocol, Section
3.4: Post-Construction Requirements). Since the question asks for the standard timeframe, 12 months (Option A) applies.
Reference:EDGE Certification Protocol, Section 3.4: Post-Construction Requirements; EDGE Expert and Auditor Protocols, Section 4.4: Site Audit Procedures; EDGE User Guide Version 2.1, Section 6.3: Post- Construction Certification.

質問 # 39
Which of the following user roles is available in the EDGE App for an EDGE project team?

• A. Project Auditor
• B. Project Engineer
• C. Project Admin
• D. Project Architect

正解：C

解説：
The EDGE App assigns specific user roles to manage project collaboration and access within the software.
The EDGE User Guide details the available roles: "In the EDGE App, user roles for project teams include Project Admin, who manages the project and has full access to edit and submit assessments, and other roles like Project Collaborator for team members contributing to the assessment. The Project Admin is responsible for overseeing the project's self-assessment and coordinating with the team" (EDGE User Guide, Section 2.2:
Project Setup). Option A, Project Admin, is explicitly listed as a role in the EDGE App. Option B (Project Architect) and Option C (Project Engineer) are not defined roles in the software, as the guide clarifies: "Roles like architect or engineer are project-specific titles, not EDGE App roles; team members are grouped under Project Admin or Collaborator" (EDGE User Guide, Section 2.2: Project Setup). Option D (Project Auditor) is also incorrect, as auditors have a separate role outside the project team: "Project Auditors are assigned by the Certification Provider and access the assessment separately, not as partof the project team's roles in the EDGE App" (EDGE Certification Protocol, Section 3.1: Certification Process). Thus, Project Admin (Option A) is the correct user role available in the EDGE App.
Reference:EDGE User Guide Version 2.1, Section 2.2: Project Setup; EDGE Certification Protocol, Section
3.1: Certification Process.

質問 # 40
As an EDGE Auditor, one requires a full set of documentation to support each green building measure selected in a project assessment. Providing this information is the responsibility of:

• A. The project design team.
• B. The Facility Manager.
• C. The Client.
• D. The Building Inspector.

正解：C

解説：
The roles and responsibilities in the EDGE certification process are clearly defined to ensure a streamlined audit process. The EDGE Certification Protocol explicitly assigns the responsibility for providing documentation to support green building measures: "The EDGE Client is responsible for providing a full set of documentation to support each green building measure selected in the project assessment. This includes drawings, specifications, manufacturer's data sheets, and any other evidence required by the Auditor to verify compliance with the EDGE standard during both the design and post-construction stages" (EDGE Certification Protocol, Section 3.1: Certification Process). Option A, the Client, directly aligns with this requirement, as the Client (typically the project owner or developer) is the primary party submitting the project for certification and must provide all necessary evidence. Option B (the Facility Manager) is incorrect because the Facility Manager's role is operational, not related to certification documentation: "Facility Managers may assist with operational data for EDGE Zero Carbon certification but are not responsible for providing design or construction documentation" (EDGE Certification Protocol, Section 2.3: Certification Levels). Option C (the Building Inspector) is also incorrect, as this role is external to the EDGE process and not involved in certification: "Building Inspectors ensure compliance with local codes, not EDGE requirements" (EDGE User Guide, Glossary). Option D (the project design team) may prepare documentation, but the responsibility lies with the Client to submit it: "While the design team often prepares technical documents, it is the Client's responsibility to compile and provide them to the Auditor as part of the certification process" (EDGE Expert and Auditor Protocols, Section 2.1: Roles of EDGE Client). The EDGE User Guide further reinforces this by stating: "The Client must ensure all supporting documentation is complete and accessible to the Auditor to avoid delays in the certification process" (EDGE User Guide, Section 6.2: Documentation Requirements). Therefore, the Client (Option A) is responsible for providing the full set of documentation for the audit.

質問 # 41
What does the EDGE Auditor provide in the EDGE certification process for a project they are auditing?

• A. Recommendation for certification
• B. Recommendation of materials and building systems
• C. Approval of the building design
• D. Building design services

正解：A

解説：
The role of the EDGE Auditor in the certification process is strictly defined to ensure independence and objectivity. The EDGE Expert and Auditor Protocols state: "The EDGE Auditor's primary role in the certification process is to conduct an independent audit of the project's self-assessment and supporting documentation, providing a recommendation for certification to the Certification Provider based on compliance with EDGE standards" (EDGE Expert and Auditor Protocols, Section 2.2: Roles of EDGE Auditor). Option C, recommendation for certification, aligns with this responsibility. Option A (building design services) and Option D (recommendation of materials and building systems) are incorrect, as these are roles of the EDGE Expert or design team, not the Auditor: "Auditors do not provide design services or recommend materials; their role is to verify, not advise" (EDGE Expert and Auditor Protocols, Section 2.3:
Conflict of Interest). Option B (approval of the building design) is also incorrect, as Auditors do not approve designs but assess compliance: "Final approval of certification is granted by the Certification Provider, not the Auditor" (EDGE Certification Protocol, Section 3.1: Certification Process). Thus, the Auditor provides a recommendation for certification (Option C).
Reference: EDGE Expert and Auditor Protocols, Section 2.2: Roles of EDGE Auditor, Section 2.3: Conflict of Interest; EDGE Certification Protocol, Section 3.1: Certification Process.

質問 # 42
VRV / VRF System is best used for:

• A. Single zone office space
• B. Single zone space
• C. Multizone space
• D. Meeting space

正解：C

解説：
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:
EnergyEfficiency 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.

質問 # 43
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. Wastewater
• B. Potable water
• C. Water savings
• D. Water usage

正解：C

解説：
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).

The Base Case for utility costs:

• A. Includes the cost of virtual energy only in homes.
• B. Excludes the cost of virtual energy.
• C. Includes the cost of virtual energy.
• D. Excludes the cost of virtual energy only in homes.

正解：C

解説：
In EDGE, the Base Case is a standardized benchmark used to calculate utility cost savings, reflecting typical resource consumption for a building in its location and typology. The term "virtual energy" in EDGE refers to the energy required for heating, cooling, lighting, and other systems, modeled as if the building operates under typical conditions without efficiency measures. The EDGE User Guide explains how utility costs are calculated: "The Base Case for utility costs includes the cost of virtual energy, which represents the modeled energy consumption for the building type in the absence of efficiency measures, alongside water consumption, using localtariffs to estimate financial impacts" (EDGE User Guide, Section 2.3: Using the EDGE App). Option B, includes the cost of virtual energy, aligns with this approach, as the Base Case accounts for all modeled energy use to establish a baseline for savings. Option A (excludes the cost of virtual energy) is incorrect, as virtual energy is a core component of the Base Case: "Virtual energy in EDGE is the theoretical energy use calculated for the Base Case, including heating, cooling, and lighting, and its cost is always included in utility cost calculations" (EDGE Methodology Report Version 2.0, Section 4.4: Cost Savings Calculations). Option C (excludes the cost of virtual energy only in homes) and Option D (includes the cost of virtual energy only in homes) are also incorrect, as the treatment of virtual energy is consistent across all typologies: "The Base Case methodology, including the inclusion of virtual energy costs, applies uniformly to all building types in EDGE, whether homes, hotels, or offices, to ensure a fair comparison of savings" (EDGE User Guide, Section 2.3: Using the EDGE App). The EDGE Methodology Report further clarifies: "Utility costs in the Base Case are derived from virtual energy and water consumption, reflecting typical usage patterns for the building type and location, ensuring that savings calculations are comprehensive and include all relevant energy demands" (EDGE Methodology Report Version 2.0, Section 4.4: Cost Savings Calculations). This consistent inclusion of virtual energy costs across all typologies makes Option B the correct answer.

質問 # 45
Which of the following must be included in the EDGE Auditor submission for Preliminary Certification?

• A. The Chapter 5 EDGE certification protocol.
• B. Compliance documents for selected measures.
• C. All of the available design data.
• D. The design audit site visit results verified by the EDGE Auditor.

正解：B

解説：
The EDGE Auditor's submission for Preliminary Certification (design stage) must include specific elements to support the recommendation for certification. The EDGE Certification Protocol specifies: "For Preliminary Certification, the EDGE Auditor's submission must include compliance documents for the selected measures, such as drawings, specifications, and manufacturer's data sheets, which verify that the design aligns with the self-assessment in the EDGE software. These documents are reviewed by the Certification Provider to confirm eligibility" (EDGE Certification Protocol, Section 3.2: Audit Requirements). Option C, compliance documents for selected measures, directly matches this requirement. Option A (all available design data) is too broad and not required: "Only documents directly related to the selected measures are needed, not all design data" (EDGE Certification Protocol, Section 3.2: Audit Requirements). Option B (Chapter 5 EDGE certification protocol) is incorrect, as this refers to the protocol document itself, not a submission component:
"The certification protocol is a reference, not part of the Auditor's submission" (EDGE Certification Protocol, Section 1.1: Overview). Option D (design audit site visit results) is incorrect, as site visits are not required at the design stage: "Preliminary Certification is based on a desk audit, not a site visit, which occurs at the post- construction stage" (EDGE Certification Protocol, Section 3.3: Certification Decision). Thus, compliance documents (Option C) are required in the submission.
Reference:EDGE Certification Protocol, Section 3.2: Audit Requirements, Section 3.3: Certification Decision, Section 1.1: Overview.

質問 # 46
An EDGE Auditor has received initial documentation from a Client which implies that measures not selected on the downloaded PDF can be claimed. What should the Auditor do?

• A. The Auditor should modify the self-assessment and submit the project for certification.
• B. The Auditor should ask for advice from the EDGE Partner and then take action.
• C. Inform the Client to update the EDGE software and prepare a new PDF.
• D. As submission documents are correct, the Auditor should ignore the error on PDF.

正解：C

解説：
The EDGE audit process requires that the documentation submitted by the Client accurately reflects the self- assessment in the EDGE software, ensuring consistency and transparency. The EDGE Expert and Auditor Protocols address discrepancies in documentation: "If an EDGE Auditor identifies a discrepancy between the submitted documentation and the self-assessment PDF, such as measures being claimed that were not selected in the EDGE software, the Auditor must inform the Client to update the EDGE software to reflect the correct measures and prepare a new PDF for submission. This ensures that the audit is based on an accurate representation of the project's claims" (EDGE Expert and Auditor Protocols, Section 4.2: Evidence Verification). Option C, inform the Client to update the EDGE software and prepare a new PDF, directly aligns with this protocol, as it corrects the error at the source and ensures the self-assessment matches the claimed measures. Option A (ask for advice from the EDGE Partner) is unnecessary, as the protocol provides clear guidance: "Auditors are expected to follow standard procedures for discrepancies without needing to consult the EDGE Partner, unless the issue involves a policy interpretation beyond the protocols" (EDGE Expert and Auditor Protocols, Section 4.1: Audit Process). Option B (modify the self-assessment and submit) is unethical and prohibited, as Auditors cannot alter the Client's submission: "The Auditor must not modify the Client's self-assessment in the EDGE software, as this compromises the independence of the audit process; the Client is responsible for updating the assessment" (EDGE Certification Protocol, Section 3.2:
Audit Requirements). Option D (ignore the error on PDF) is also incorrect, as ignoring discrepancies violates audit integrity: "All discrepancies between the PDF and submitted documents must be resolved before the audit proceeds, as ignoring errors could lead to incorrect certification outcomes" (EDGE Expert and Auditor Protocols, Section 4.2: Evidence Verification). The EDGE User Guide further reinforces: "The self- assessment PDF must accurately reflect the measures selected in the EDGE software, and any mismatch requires the Client to revise the assessment to ensure a fair and transparent audit" (EDGE User Guide, Section
6.2: Documentation Requirements). Thus, the Auditor should inform the Client to update the software and prepare a new PDF (Option C).

質問 # 47
During an EDGE audit for a project, the Auditor discovers that members of the design team have provided misleading information on certain green building measures to the Client. This incorrect information has unknowingly been used by the Client to support their application for EDGE certification. What should the EDGE Auditor do?

• A. Contact the Client and warn them of the deception, pointing out the design team members at fault.
• B. Reject the information and adjust the EDGE assessment accordingly, returning the assessment to the Client.
• C. Call the offending design team member and negotiate a friendly solution.
• D. Contact the design team and recommend that they provide updated and correct information.

正解：D

解説：
EDGE Auditors are bound by ethical protocols to maintain professionalism and independence when encountering issues like misleading information. The EDGE Expert and Auditor Protocols outline the procedure: "If an EDGE Auditor discovers misleading or incorrect information during an audit,they must contact the design team to recommend that they provide updated and correct information to the Client. The Auditor should document the issue in the audit report but must not adjust the assessment themselves or take punitive actions, ensuring the process remains transparent and fair" (EDGE Expert and Auditor Protocols, Section 4.3: Handling Discrepancies). Option B, contacting the design team to recommend updated information, aligns with this protocol. Option A (negotiate a friendly solution) violates the Auditor's impartiality: "Auditors must avoid direct negotiations that could compromise their independence" (EDGE Expert and Auditor Protocols, Section 2.3: Conflict of Interest). Option C (warn the Client of deception) oversteps the Auditor's role by assigning blame: "Auditors should not accuse parties of deception but focus on facilitating corrections" (EDGE Expert and Auditor Protocols, Section 4.3: Handling Discrepancies).
Option D (reject and adjust the assessment) is incorrect, as Auditors cannot modify assessments: "Auditors must assess the project as submitted and cannot reject or adjust measures on their own" (EDGE Certification Protocol, Section 3.2: Audit Requirements). Thus, recommending corrections to the design team (Option B) is the appropriate action.

質問 # 48
Energy consumption calculations in EDGE are based on:

• A. Quasi-steady state calculations.
• B. Cooling and heating degree days.
• C. Steady state calculations.
• D. Hourly simulation.

正解：C

解説：
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.
Reference:EDGE Methodology Report Version 2.0, Section 5.2: Energy Calculation Methods; EDGE User Guide Version 2.1, Section 2.1: EDGE Software Overview, Section 3.2: Climate Data Inputs.

質問 # 49
Variable speed drives in HVAC systems help:

• A. Reduce water consumption.
• B. Increase the speed.
• C. Reduce the speed.
• D. Reduce energy consumption.

正解：D

解説：
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).
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.
