NEW QUESTION # 15
Which of the following building types is NOT covered by EDGE?
- A. Schools
- B. Warehouses
- C. Hospitals
- D. Factories (heavy industry)
Answer: D
Explanation:
EDGE certification applies to specific building typologies that align with its focus on resource efficiency in new constructions and major renovations. The EDGE User Guide lists the covered building types: "EDGE certification is available for the following building typologies: homes, hotels, offices, hospitals, retail, schools, warehouses, and light industry buildings. These typologies are selected because they have predictable energy, water, and materials usage patterns that can be modeled in the EDGE software" (EDGE User Guide, Section 1.2: Scope of EDGE Certification). Option A (hospitals), Option B (schools), and Option D (warehouses) are explicitly included in this list, making them eligible for EDGE certification. However, Option C (factories - heavy industry) is not covered, as clarified in the EDGE Certification Protocol: "Heavy industry factories are not covered by EDGE, as their energy and water usage patterns are highly variable and process-driven, making them unsuitable for the standardized modeling approach used in EDGE. Light industry buildings, such as small manufacturing facilities with predictable usage, are included, but heavy industry, such as steel production or chemical manufacturing, is excluded" (EDGE Certification Protocol, Section 1.2: Scope of EDGE Standard). The EDGE Methodology Report further explains: "Heavy industry factories involve complex industrial processes that dominate resource consumption, which cannot be accurately modeled using EDGE's simplified methodology, unlike hospitals, schools, or warehouses, which have more consistent occupancy and usage patterns" (EDGE Methodology Report Version 2.0, Section 2.1:
Calculation Approach). The EDGE User Guide also notes: "Building types like heavy industry factories are outside the scope of EDGE, as the software is designed for commercial and residential buildings with typical HVAC, lighting, and water demands" (EDGE User Guide, Section 1.2: Scope of EDGE Certification).
Therefore, factories (heavy industry) (Option C) is the building type not covered by EDGE.

NEW QUESTION # 16
Which building typology should benefit the most from having a wastewater treatment and recycling system?
- A. Homes
- B. Hotel
- C. School
- D. Office
Answer: B
Explanation:
Wastewater treatment and recycling systems are evaluated in EDGE for their potential to reduce water consumption, a key aspect of green building design. The EDGE User Guide highlights the varying water usage patterns across building typologies: "Hotels typically have high water consumption due to guest rooms, laundry, and amenities like pools, making them ideal candidates for wastewater treatment and recycling systems, which can significantly reduce potable water demand by reusing treated water for non-potable uses such as irrigation and flushing" (EDGE User Guide, Section 5.2: Water Efficiency Measures). In contrast, homes (Option A) and offices (Option D) generally have lower per-capita water use, and schools (Option C) have intermittent occupancy, reducing the overall impact of such systems. The EDGE Methodology Report further supports this, noting: "For hotels, greywater and blackwater recycling can achieve up to 40% water savings due to high occupancy and consistent demand, compared to 20-25% in homes or offices" (EDGE Methodology Report Version 2.0, Section 4.2: Water Savings Calculations). Thus, hotels (Option B) benefit the most from wastewater treatment and recycling systems due to their high water usage andpotential for significant savings.
Reference:EDGE User Guide Version 2.1, Section 5.2: Water Efficiency Measures; EDGE Methodology Report Version 2.0, Section 4.2: Water Savings Calculations.
NEW QUESTION # 17
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 design team and recommend that they provide updated and correct information.
- B. Reject the information and adjust the EDGE assessment accordingly, returning the assessment to the Client.
- C. Contact the Client and warn them of the deception, pointing out the design team members at fault.
- D. Call the offending design team member and negotiate a friendly solution.
Answer: A
Explanation:
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.
Reference:EDGE Expert and Auditor Protocols, Section 4.3: Handling Discrepancies, Section 2.3: Conflict of Interest; EDGE Certification Protocol, Section 3.2: Audit Requirements.
NEW QUESTION # 18
Increasing the glazing area of an office building will NOT impact which of the following?
- A. Heating demand
- B. Hot water demand
- C. Lighting energy
- D. Cooling demand
Answer: B
Explanation:
Increasing the glazing area in an office building affects various aspects of energy consumption due to changes in heat gain, heat loss, and natural light availability, but it does not influence all buildingsystems. The EDGE User Guide explains the impacts of glazing: "Increasing the glazing area (window-to-wall ratio, WWR) in an office building typically increases cooling demand due to higher solar heat gain, increases heating demand in colder climates due to greater heat loss through windows, and reduces lighting energy by allowing more natural daylight, assuming proper daylighting design" (EDGE User Guide, Section 3.5: Passive Design Strategies). Option A (cooling demand) is affected, as more glazing increases solar heat gain: "Higher WWR leads to greater cooling loads in hot climates due to increased solar radiation entering the building" (EDGE Methodology Report Version 2.0, Section 5.2: Energy Calculation Methods). Option B (heating demand) is also impacted, particularly in cooler climates: "Larger glazing areas increase heat loss in cold climates, raising heating demand due to the lower thermal resistance of windows compared to walls" (EDGE User Guide, Section 4.1: Insulation Measures). Option C (lighting energy) is affected, as more glazing can reduce the need for artificial lighting: "Increased glazing can lower lighting energy by enhancing daylight penetration, provided glare is controlled" (EDGE User Guide, Section 4.4: Lighting Efficiency Measures). However, Option D (hot water demand) is not impacted by glazing area, as hot water use is tied to occupant activities (e.
g., showers, cleaning) rather than building envelope design: "Hot water demand in EDGE is determined by occupant use patterns, such as the number of showers or laundry cycles, and is not influenced by glazing area or WWR" (EDGE Methodology Report Version 2.0, Section 4.2: Water Savings Calculations). The EDGE User Guide further confirms: "Glazing area impacts energy-related metrics like cooling, heating, and lighting, but has no direct effect on hot water demand, which is calculated separately based on usage assumptions" (EDGE User Guide, Section 5.2: Water Efficiency Measures). Therefore, increasing glazing area does not impact hot water demand (Option D).
Reference:EDGE User Guide Version 2.1, Section 3.5: Passive Design Strategies, Section 4.1: Insulation Measures, Section 4.4: Lighting Efficiency Measures, Section 5.2: Water Efficiency Measures; EDGE Methodology Report Version 2.0, Section 5.2: Energy Calculation Methods, Section 4.2: Water Savings Calculations.
NEW QUESTION # 19
In a 3-star business hotel near the city center, which of the following elements of the building's water use breakdown is/are likely to consume the most water?
- A. Toilets in lobby area
- B. Laundry
- C. Showers in guest rooms
- D. Faucets in guest rooms
Answer: C
Explanation:
Water consumption in hotels varies significantly based on usage patterns, with guest-related activities often dominating the water use breakdown. The EDGE User Guide provides detailed insights into water use in hotels: "In a typical 3-star business hotel, the largest contributor to water consumption is showers in guest rooms, accounting for approximately 40-50% of total water use due to frequent guest showers, especially in urban hotels with high occupancy. Laundry, toilets, and faucets also contribute, but to a lesser extent, with laundry at 15-20%, toilets at 10-15%, and faucets at 5-10%" (EDGE User Guide, Section 5.2: Water Efficiency Measures). Option A, showers in guest rooms, aligns with this breakdown as the element likely to consume the most water. Option B (laundry) is significant but lower than showers: "Laundry in 3-star hotels consumes less water than showers, as laundry is typically centralized and less frequent than daily guest showers" (EDGE Methodology Report Version 2.0, Section 4.2: Water Savings Calculations). Option C (toilets in lobby area) is a minor contributor, as lobby toilets serve fewer users compared to guest rooms:
"Toilets in public areas like the lobby have lower usage compared to guest room facilities, contributing only a small fraction of total water use in hotels" (EDGE User Guide, Section 5.2: Water Efficiency Measures).
Option D (faucets in guest rooms) also uses less water than showers: "Faucets in guest rooms, used for handwashing or brushing teeth, have lower flow rates and usage frequency compared to showers, which often run for 5-10 minutes per use" (EDGE Methodology Report Version 2.0, Section 4.2: Water Savings Calculations). The EDGE User Guide further elaborates: "In business hotels, showers dominate water use due to high occupancy and guest behavior, making measures like low-flow shower heads particularly effective for water savings" (EDGE User Guide, Section 5.2: Water Efficiency Measures). The EDGE Methodology Report adds: "For a 3-star hotel with 100 rooms and 70% occupancy, showers can account for 45 liters per guest per day, compared to 15 liters for laundry, 10 liters for toilets, and 5 liters for faucets, based on standard usage assumptions" (EDGE Methodology Report Version 2.0, Section 4.2: Water Savings Calculations).
Thus, showers in guest rooms (Option A) are likely to consume the most water in this context.

NEW QUESTION # 20
Which of the following describes a more efficient lamp?
- A. Longer life
- B. Lower watts/m²
- C. More lumens/watt
- D. Lower wattage
Answer: C
Explanation:
Lamp efficiency in EDGE is a key factor in reducing energy consumption for lighting, a critical green building design strategy. The EDGE User Guide defines lamp efficiency: "In EDGE, a moreefficient lamp is one that provides higher lumens per watt, meaning it produces more light output (lumens) for the same electrical input (watts). This metric, known as luminous efficacy, is used to evaluate lighting efficiency measures like EEM22 - Efficient Lighting for Internal Areas" (EDGE User Guide, Section 4.4: Lighting Efficiency Measures). Option A, more lumens/watt, directly aligns with this definition, as it indicates greater efficiency in converting electricity to light. Option B (lower watts/m²) refers to lighting power density, which is a design metric, not a lamp characteristic: "Watts/m² is a measure of lighting power density for a space, not the efficiency of an individual lamp" (EDGE Methodology Report Version 2.0, Section 5.4: Lighting Calculations). Option C (longer life) relates to durability, not efficiency: "Lamp life affects maintenance costs but is not a direct measure of energy efficiency in EDGE" (EDGE User Guide, Section 4.4: Lighting Efficiency Measures). Option D (lower wattage) alone does not indicate efficiency, as a lamp with lower wattage but poor light output would be less efficient: "Lower wattage must be paired with adequate lumens to improve efficiency" (EDGE Methodology Report Version 2.0, Section 5.4: Lighting Calculations). Thus, more lumens/watt (Option A) describes a more efficient lamp.
Reference:EDGE User Guide Version 2.1, Section 4.4: Lighting Efficiency Measures; EDGE Methodology Report Version 2.0, Section 5.4: Lighting Calculations.
NEW QUESTION # 21
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 5 years
- B. At least 3 years
- C. At least 2 years
- D. At least 1 year
Answer: B
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.

NEW QUESTION # 23
During a design audit, an EDGE Auditor notices that the project does not meet the EDGE standard for energy.
Which of the following is an acceptable course of action for the Auditor?
- A. As the project does not qualify for EDGE certification, the EDGE Auditor does not have to take any further action on the project.
- B. Based on the Auditor's previous experience on working on similar projects, provide a list of measures that the Client could incorporate in the project that will take them comfortably over the EDGE standard.
- C. Contact the design team directly to work with them to find a solution to improve the energy efficiency performance of the project.
- D. Ask the Client to use the EDGE tool again to identify options that will take the project comfortably over the EDGE standard.
Answer: D
Explanation:
The role of an EDGE Auditor during a design audit (Preliminary Certification stage) is to verify compliance with the EDGE standard, which requires at least 20% savings in energy, water, and embodied energy in materials. If the project does not meet the standard, the Auditor must follow specific protocols without overstepping their role. The EDGE Expert and Auditor Protocols outline the acceptable actions: "If a project does not meet the EDGE standard for energy during a design audit, the Auditor should inform the Client of the shortfall and ask them to use the EDGE tool again to identify additional measures that will take the project comfortably over the EDGE standard (e.g., 20% energy savings). The Auditor must not provide design advice or modify the assessment themselves, as their role is to verify, not consult" (EDGE Expert and Auditor Protocols, Section 4.1: Audit Process). Option A, ask the Client to use the EDGE tool again to identify options that will take the project comfortably over the EDGE standard, directly aligns with this guidance, as it keeps the Auditor in a verification role while encouraging the Client to revise their design. Option B (contact the design team directly to work with them) is incorrect, as it violates the Auditor's independence: "The Auditor must not engage directly with the design team to improve the project, as this constitutes consultancy, which conflicts with their role as an independent verifier" (EDGE Expert and Auditor Protocols, Section 2.3:
Conflict of Interest). Option C (take no further action) is also incorrect, as the Auditor has a responsibility to report the shortfall: "If a project does not meet the EDGE standard, the Auditor must document the failure in the audit report and inform the Client, rather than abandoning the process" (EDGE Certification Protocol, Section 3.2: Audit Requirements). Option D (provide a list of measures based on the Auditor's experience) oversteps the Auditor's role by offering consultancy: "The Auditor cannot provide specific design recommendations or measures, as this compromises their impartiality; they must direct the Client to use the EDGE software or consult an EDGE Expert" (EDGE Expert and Auditor Protocols, Section 2.3: Conflict of Interest). The EDGE User Guide further supports: "During a design audit, the Auditor's role is to assess compliance, not to guide the design process; if the project falls short, the Client should revisit the EDGE tool to explore additional measures, potentially with the help of an EDGE Expert" (EDGE User Guide, Section
6.5: Working with EDGE Auditors). The EDGE Certification Protocol adds: "The Auditor's report should note the energy shortfall and recommend that the Client revise the self-assessment to meet the 20% savings threshold, ensuring the process remains Client-driven" (EDGE Certification Protocol, Section 3.2: Audit Requirements). Thus, asking the Client to use the EDGE tool again (Option A) is the acceptable course of action.

NEW QUESTION # 24
The Client informs an EDGE Auditor that a key member of the design team has resigned. The Client requests the Auditor to take the member's place for the remainder of the project's design development as it would provide the Auditor an opportunity to identify suitable green building measures, making audit tasks much simpler. What should the EDGE Auditor do?
- A. Refer the Client to an associate within the organization who will be working with the Auditor on the EDGE audit, since the Auditor organization has spare capacity.
- B. Resign from the audit role on the basis that its position has been compromised by this direct approach by the Client.
- C. Refer the Client to an associate within the organization who works in another department, but is qualified and available to carry out the work.
- D. Accept the additional commission on the basis that this will save the Client time and money, and would reduce the volume of work required for the audit.
Answer: C
Explanation:
The EDGE framework strictly prohibits Auditors from engaging in roles that could compromise their independence, such as providing design consultancy on the same project they are auditing. The EDGE Expert and Auditor Protocols address this scenario explicitly: "An EDGE Auditor must not accept any role in the design development of a project they are auditing, as this creates a conflict of interest by blurring the lines between consultancy and independent verification. If the Client requests the Auditor to take on a design role, the Auditor should decline and may refer the Client to another qualified professional who is not involved in the audit process" (EDGE Expert and Auditor Protocols, Section 2.3: Conflict of Interest). Option B, refer the Client to an associate within the organization who works in another department, but is qualified and available to carry out the work, aligns with this guidance, as it maintains the Auditor's independence while helping the Client find a suitable replacement. Option A (resign from the audit role) is an overreaction, as the request itself does not compromise the Auditor's position unless accepted: "The Auditor is not required to resign unless they have already engaged in a conflicting role, which can be avoided by declining the request" (EDGE Expert and Auditor Protocols, Section 4.1: Audit Process). Option C (accept the additional commission) is unethical, as it violates conflict-of-interest rules: "Accepting a design role on a project being audited undermines the Auditor's impartiality, as they would be auditing theirown work, which is strictly prohibited" (EDGE Certification Protocol, Section 3.1: Certification Process). Option D (refer the Client to an associate working with the Auditor on the EDGE audit) is also incorrect, as this associate is already involved in the audit, creating a potential conflict: "Referring the Client to someone involved in the same audit does not resolve the conflict of interest, as the audit team must remain independent from design activities" (EDGE Expert and Auditor Protocols, Section 2.3: Conflict of Interest). The EDGE User Guide reinforces this principle: "Auditors must maintain strict separation from design roles to ensure an unbiased audit, and should assist the Client by referring them to independent professionals if needed" (EDGE User Guide, Section 6.5:
Working with EDGE Auditors). Thus, referring the Client to a qualified associate in another department (Option B) is the correct action.

NEW QUESTION # 25
Which of the following does NOT contribute to an EDGE Auditor maintaining their Auditor status?
- A. Studying the EDGE user guides as and when they are updated.
- B. Attending refresher training.
- C. Retaking the auditor exam.
- D. Performing at least one project site audit every two years.
Answer: C
Explanation:
Maintaining EDGE Auditor status involves specific requirements to ensure ongoing competence. The EDGE Expert and Auditor Protocols outline these requirements: "To maintain their status, EDGE Auditors must perform at least one project site audit every two years, attend refresher training as required by IFC, and stay updated by studying the EDGE user guides and protocols as they are revised" (EDGE Expert and Auditor Protocols, Section 5.1: Maintaining Auditor Status). Option A (performing at least one project site audit every two years) is explicitly required to demonstrate active engagement. Option B (studying the EDGE user guides as updated) is also necessary to stay current with program changes. Option D (attending refresher training) is mandated to ensure continued education. However, Option C (retaking the auditor exam) is not a requirement for maintaining status: "Once certified, EDGE Auditors are not required to retake the exam to maintain their status, though they may need to retake it if their certification lapses or if significant program changes occur" (EDGE Expert and Auditor Protocols, Section 5.2: Recertification Conditions). Since the question focuses on maintaining status, not recertification after lapse, retaking the exam is not a standard requirement. Thus, retaking the auditor exam (Option C) does not contribute to maintaining Auditor status.
Reference:EDGE Expert and Auditor Protocols, Section 5.1: Maintaining Auditor Status, Section 5.2:
Recertification Conditions.
NEW QUESTION # 26
A potential EDGE Client is pursuing EDGE Zero Carbon certification for a museum. Which of the following statements is correct?
- A. The building must be operating for at least 12 months at 75% occupancy.
- B. The project team can select any typology they consider applicable.
- C. The project cannot be certified because EDGE does not have a 'museum' typology.
- D. The building must be operating for at least 6 months at 75% occupancy.
Answer: C
Explanation:
EDGE Zero Carbon certification, like all EDGE certifications, is limited to specific building typologies supported by the EDGE software, as these typologies have predefined usage patterns for accurate modeling.
The EDGE User Guide lists the supported typologies: "EDGE certification, including EDGE Zero Carbon, is available for the following building typologies: homes, hotels, offices, hospitals, retail, schools, warehouses, and light industry buildings. Museums are not a supported typology in EDGE, as their unique usage patterns, such as specialized HVAC for artifact preservation, are not modeled in the software" (EDGE User Guide, Section 1.2: Scope of EDGE Certification). Option C, the project cannot be certified because EDGE does not have a 'museum' typology, directly aligns with this limitation, as museums are not among the supported building types. Option A (the project team can select any typology they consider applicable) is incorrect, as EDGE requires the use of predefined typologies: "The EDGE software restricts typology selection to predefined categories to ensure accurate Base Case calculations; users cannot create custom typologies for unsupported building types like museums" (EDGE Methodology Report Version 2.0, Section 2.1: Calculation Approach). Option B (operating for at least 6 months at 75% occupancy) and Option D (operating for at least
12 months at 75% occupancy) address operational data requirements for EDGE Zero Carbon, but they are irrelevant if the typology is unsupported: "EDGE Zero Carbon certification requires at least 12 months of operational data at 75% occupancy to verify performance, but this applies only to supported typologies" (EDGE Certification Protocol, Section 2.3: Certification Levels). Since museums are not supported, the operational data requirement does not apply, making both B and D incorrect in this context. The EDGE Certification Protocol further confirms: "Buildings like museums, which are not part of EDGE's typology list, cannot be certified, as the software cannot generate a Base Case for unsupported building types, ensuring consistency in certification standards" (EDGE Certification Protocol, Section 1.2: Scope of EDGE Standard).
The EDGE User Guide adds: "Clients pursuing certification for unsupported typologies, such as museums or cultural centers, will need to explore other green building certifications, as EDGE is not designed for these building types" (EDGE User Guide, Section 1.2: Scope of EDGE Certification). Thus, the project cannot be certified due to the lack of a museum typology (Option C).
Reference:EDGE User Guide Version 2.1, Section 1.2: Scope of EDGE Certification; EDGE Certification Protocol, Section 1.2: Scope of EDGE Standard, Section 2.3: Certification Levels; EDGE Methodology Report Version 2.0, Section 2.1: Calculation Approach.
NEW QUESTION # 27
Which of the following measures provides the most attractive solution in the EDGE software for a hospital?
- A. External shading with 7% saving and 8 years payback
- B. Insulation of external walls with 3% saving and 9 years payback
- C. Solar hot water system with a saving of 15% and payback of 6 years
- D. Water-cooled chillers with 20% energy saving and 10 years payback
Answer: C
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.
Reference:EDGE User Guide Version 2.1, Section 2.4: Interpreting EDGE Results; EDGE Methodology Report Version 2.0, Section 5.3: Energy Measures, Section 4.2: Energy Savings Calculations.
NEW QUESTION # 28
Which of the following is NOT a characteristic of the EDGE standard?
- A. Simple, as beneath the intuitive interface is a powerful engine that understands local climate and how buildings will be used
- B. Smart, as capital costs and payback period for buildings are displayed
- C. Holistic approach that takes into account wider sustainability issues
- D. Fast tool with ideal measures for the best return on investment
Answer: C
Explanation:
The EDGE standard is designed to be a practical, focused tool for green building certification, emphasizing specific resource efficiency metrics. The EDGE User Guide describes its characteristics: "EDGE is a simple, fast, and smart tool for green building certification. It provides an intuitive interface with a powerful engine that accounts for local climate and building use (simple), identifies measures with the best return on investment (fast), and displays capital costs and payback periods (smart)" (EDGE User Guide, Section 1.1:
Introduction to EDGE). Options A, C, and D align with these descriptions. However, Option B (holistic approach that takes into account wider sustainability issues) is not a characteristic of EDGE, as the standard focuses narrowly on energy, water, and embodied energy in materials, not broader sustainability issues like biodiversity or social equity. This is clarified in the EDGE Certification Protocol: "EDGE is not a holistic sustainability standard; it specifically targets resource efficiency in energy, water, and materials, excluding wider sustainability metrics such as indoor air quality or ecological impact" (EDGE Certification Protocol, Section 1.2: Scope of EDGE Standard). Thus, Option B is not a characteristic of the EDGE standard.
Reference: EDGE User Guide Version 2.1, Section 1.1: Introduction to EDGE; EDGE Certification Protocol, Section 1.2: Scope of EDGE Standard.
NEW QUESTION # 29
Which type of evidence is required at the post-construction stage for the efficiency measure window glazing?
- A. Design building elevations marking the window glass specifications
- B. Manufacturer's data sheets showing the make and model, U-value, and SHGC of the installed glass
- C. Bill of quantities with the specifications for the window glass highlighted
- D. Window schedule for the building showing the major window glass types if more than one type of glass is present
Answer: B
Explanation:
The post-construction stage in EDGE certification requires evidence to confirm that the efficiency measures claimed in the design stage have been implemented as specified. For window glazing, which affects energy efficiency through its U-value (thermal transmittance) and SHGC (Solar Heat Gain Coefficient), the EDGE Certification Protocol provides clear requirements: "At the post-construction stage, the Client must provide manufacturer's data sheets for the window glazing measure, showing the make and model, U-value, and SHGC of the installed glass, to confirm that the glazing matches the specifications claimed in the self- assessment and meets the energy efficiency requirements" (EDGE Certification Protocol, Section 3.4: Post- Construction Requirements). Option C, manufacturer's data sheets showing the make and model, U-value, and SHGC of the installed glass, directly matches this requirement, as it provides the specific technical data needed to verify compliance. Option A (design building elevations marking the window glass specifications) is relevant at the design stage, not post-construction: "Design elevations are required at the preliminary stage to show intended glazing specifications, not after construction" (EDGE Certification Protocol, Section 3.2:
Audit Requirements). Option B (bill of quantities with specifications highlighted) is insufficient on its own, as it may not provide detailed technical data: "Bills of quantities may support purchase verification, but manufacturer's data sheets are required for technical specifications like U-value and SHGC" (EDGE Certification Protocol, Section 3.4: Post-Construction Requirements). Option D (window schedule showing major glass types) is helpful but not sufficient, as it lacks the detailed technical data: "Window schedules may indicate glass types, but they do not replace the need for manufacturer's data sheets with U-value and SHGC at post-construction" (EDGE User Guide, Section 6.2: Documentation Requirements). The EDGE User Guide further clarifies: "For glazing measures, post-construction evidence must confirm the installed product's performance through manufacturer's data sheets, ensuring alignment with the design-stage claims" (EDGE User Guide, Section 4.1: Insulation Measures). Thus, manufacturer's data sheets (Option C) are required at the post-construction stage.

NEW QUESTION # 30
Which of the following is a required measure?
- A. Green roof
- B. Lighting controls
- C. Insulation of roof
- D. Efficient lighting for internal areas
Answer: C
Explanation:
In EDGE, certain measures are mandatory to ensure a baseline level of resource efficiency, while others are optional depending on the project's goals. The EDGE User Guide specifies mandatory measures for certification: "To achieve EDGE certification, projects must meet minimum requirements, including mandatory measures such as insulation of the roof to reduce heat gain or loss, ensuring a basic level of energy efficiency across all building typologies in climates where thermal performance is relevant" (EDGE User Guide, Section 4.1: Insulation Measures). Option B, insulation of roof, is identified as a required measure in EDGE, particularly in climates where heating or cooling loads are significant, which applies to most regions.
Option A (green roof) is an optional measure, not mandatory: "Green roofs are an optional measure in EDGE, contributing to energy and water savings but not required for certification" (EDGE User Guide, Section 4.5:
Additional Energy Measures). Option C (lighting controls) is also optional, as EDGE allows flexibility in lighting strategies: "Lighting controls, such as occupancy sensors, are optional measures that can enhance energy savings but are not mandatory" (EDGE User Guide, Section 4.4: Lighting Efficiency Measures).
Option D (efficient lighting for internal areas) is encouraged but not required: "Efficient lighting for internal areas (EEM22) is an optional measure, requiring at least 90% of lamps to be efficient, but projects can achieve certification without it if other energy measures meet the 20% savings threshold" (EDGE User Guide, Section 4.4: Lighting Efficiency Measures). The EDGE Certification Protocol reinforces this: "Mandatory measures like roof insulation ensure a minimum standard of energy efficiency, while measures like green roofs, lighting controls, and efficient lighting are optional and contribute to overall savings" (EDGE Certification Protocol, Section 2.2: Certification Requirements). Therefore, insulation of the roof (Option B) is the required measure among the options.
