The EDGE certification process involves various fees, including registration and certification fees, and assigns clear responsibility for their payment. The EDGE Certification Protocol explicitly states: "The EDGE Client, typically the project owner or developer, is responsible for paying the EDGE certification fees, which include the registration fee to enter the project into the system and the certification fee upon successful completion of the audit process. These fees are paid to the EDGE Certification Provider to cover the costs of certification" (EDGE Certification Protocol, Section 2.1: Registration). Option B, EDGE Client, directly aligns with this responsibility, as the Client is the party seeking certification and thus bears the financial obligation. Option A (EDGE Expert) is incorrect, as the Expert provides consultancy services and is typically paid by the Client, not responsible for certification fees: "The EDGE Expert may assist with the certification process, but the Client is responsible for all fees associated with registration and certification" (EDGE Expert and Auditor Protocols, Section 2.1: Roles of EDGE Expert). Option C (EDGE Operations and Management Team) is also incorrect, as this team oversees the EDGE program, not individual project fees: "The EDGE Operations and Management Team manages the program at a global level and does not handle or pay project-specific certification fees" (EDGE Certification Protocol, Section 1.3: Program Structure). Option D (Local Green Building Council) may act as a Certification Provider in some regions, but they receive the fees, not pay them: "Local Green Building Councils, such as those partnered with GBCI, may serve as Certification Providers, but the payment of fees is the responsibility of the Client, not the Council" (EDGE User Guide, Section 6.1: Project Preparation). The EDGE User Guide further reinforces: "The Client must budget for andpay all EDGE certification fees, ensuring timely payment to the Certification Provider to avoid delays in the certification process" (EDGE User Guide, Section 6.1: Project Preparation). The EDGE Certification Protocol adds: "Certification fees are typically invoiced by the Certification Provider, such as GBCI, and must be settled by the Client to receive the final EDGE certificate" (EDGE Certification Protocol, Section 3.3: Certification Decision). Thus, the EDGE Client (Option B) is responsible for paying the certification fees.

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.

Adoption of green building practices in EDGE is influenced by factors that incentivize or mandate resource efficiency. The EDGE User Guide discusses drivers for green building adoption: "Factors that lead to higher adoption of green building practices include green building regulations, which mandate compliance with efficiency standards; public awareness and capacity building, which educate stakeholders on the benefits of green design; and clear visibility of estimated savings and costs, which provide financial justification for green measures" (EDGE User Guide, Section 1.1: Introduction to EDGE). Option A (green building regulations) directly encourages adoption by enforcing standards: "Regulations requiring energy or water efficiency standards push developers to adopt green practices to meet legal requirements" (EDGE Certification Protocol, Section 1.2: Scope of EDGE Standard). Option C (public awareness and capacity building) increases adoption by educating stakeholders: "Awareness campaigns and training programs increase demand for greenbuildings by informing developers, owners, and tenants of their benefits" (EDGE User Guide, Section 1.1: Introduction to EDGE). Option D (clear visibility of estimated savings and costs) incentivizes adoption by demonstrating financial benefits: "EDGE’s display of savings and payback periods motivates adoption by showing the return on investment for green measures" (EDGE User Guide, Section 2.4: Interpreting EDGE Results). However, Option B (lower electricity supply costs) may not lead to higher adoption, as it reduces the financial incentive to save energy: "Lower electricity supply costs decrease the cost savings from energy efficiency measures, potentially discouraging investment in green practices, as the payback period for measures like insulation or efficient lighting becomes longer" (EDGE Methodology Report Version 2.0, Section 4.4: Cost Savings Calculations). The EDGE User Guide further elaborates: "High utility costs often drive green building adoption by making energy and water savings more financially attractive, whereas lower costs can reduce the urgency to implement efficiency measures" (EDGE User Guide, Section 1.2: Scope of EDGE Certification). In this context, lower electricity supply costs (Option B) may not encourage green building practices, as the economic motivation for energy savings diminishes.

Pool covers are a water and energy efficiency measure in EDGE, particularly relevant for hotels with swimming pools. The EDGE User Guide outlines their benefits: "Pool covers reduce water demand by minimizing evaporation and energy demand by reducing the need for heating, as they retain heat in the pool. In EDGE, the use of pool covers is recognized for its dual impact on reducing both water and energy consumption" (EDGE User Guide, Section 5.3: Additional Water Efficiency Measures). Option B, reduce both water and energy demand, directly aligns with this description. Option A (increase solar control and comfort) is incorrect, as pool covers are not recognized in EDGE for solar control or occupant comfort but for resource savings. Option C (require less maintenance and work from employees) and Option D (reduce chemical consumption and that of cleaning products) are potential secondary benefits but are not quantified or recognized in EDGE calculations, as confirmed by: "EDGE focuses on measurable water and energy savings from pool covers, not on maintenance or chemical use reductions" (EDGE Methodology Report Version 2.0, Section 4.3: Water Efficiency Calculations). Thus, Option B is the correct answer.

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).

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).

Embodied carbon in EDGE refers to the carbon emissions associated with the production, transportation, and installation of building materials, a key metric for materials efficiency. The EDGE User Guide specifies how this is measured: "In the EDGE software, the embodied carbon of materials is quantified in kilograms of carbon dioxide equivalent (kgCO2), reflecting the total greenhouse gas emissions associated with the material’s lifecycle, from extraction to installation"(EDGE User Guide, Section 7.2: Materials Efficiency Measures). Option A, kgCO2, directly matches this unit, as EDGE uses kgCO2 to standardize carbon emissions across materials, allowing for comparison and aggregation in the software’s results. Option B (MJ) is incorrect, as MJ (megajoules) measures embodied energy, not carbon: "Embodied energy in EDGE is measured in MJ, representing the energy consumed in material production, while embodied carbon is separately calculated in kgCO2 to assess environmental impact" (EDGE Methodology Report Version 2.0, Section 6.1: Embodied Energy in Materials). Option C (BTU) is also incorrect, as BTU (British Thermal Units) is an energy unit not used in EDGE for carbon calculations: "EDGE uses metric units like MJ for energy and kgCO2 for carbon; BTU is not a standard unit in the software" (EDGE User Guide, Section 2.3: Using the EDGE App). Option D (kWh) is another energy unit, typically used for operational energy, not embodied carbon: "kWh is used in EDGE to measure operational energy consumption, such as electricity use, but not for embodied carbon, which is always in kgCO2" (EDGE Methodology Report Version 2.0, Section 5.2: Energy Calculation Methods). The EDGE User Guide further clarifies: "The software displays embodied carbon in kgCO2 to align with global carbon accounting standards, enabling users to understand the environmental footprint of their material choices" (EDGE User Guide, Section 7.2: Materials Efficiency Measures). The EDGE Methodology Report adds: "For example, concrete might have an embodied carbon of 0.15 kgCO2 per kg, allowing users to compare materials like fly ash concrete versus standard concrete in terms of carbon impact" (EDGE Methodology Report Version 2.0, Section 6.1: Embodied Energy in Materials). Thus, the unit of embodied carbon in EDGE is kgCO2 (Option A).

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).

EDGE Zero Carbon certification requires periodic renewal to ensure ongoing compliance with zero carbon standards, particularly since it often involves carbon offsets or renewable energy commitments that may change over time. The EDGE Certification Protocol specifies the renewal timeline: "EDGE Zero Carbon certification must be renewed initially after two years to verify that the building continues to meet the zero carbon requirements, including the use of carbon offsets or renewable energy. Subsequently, renewal is required every four years to ensure long-term compliance with the standard" (EDGE Certification Protocol, Section 2.3: Certification Levels). Option A, initially after two years, subsequently every four years, directly matches this requirement.Option B (initially after four years, subsequently every two years) reverses the timeline, which does not align with the protocol: "The initial two-year renewal ensures early verification, while the four-year cycle applies thereafter to balance monitoring with practicality" (EDGE Certification Protocol, Section 2.3: Certification Levels). Option C (every two years if using carbon offsets, or every four years if using 100% renewable energy) and Option D (every four years if using carbon offsets, or every two years if using 100% renewable energy) introduce a distinction based on the method of achieving zero carbon status, which is not supported by EDGE documentation: "The renewal timeline for EDGE Zero Carbon is consistent regardless of whether carbon offsets or renewable energy are used, as both methods require ongoing verification of performance and offset purchases" (EDGE User Guide, Section 6.3: Advanced Certifications). The EDGE Methodology Report adds: "The two-year initial renewal allows for confirmation of operational data and offset validity, while the four-year subsequent renewal cycle ensures sustained commitment without excessive administrative burden" (EDGE Methodology Report Version 2.0, Section 2.3: Zero Carbon Calculations). The EDGE User Guide further confirms: "EDGE Zero Carbon certification renewal follows a standard schedule of two years initially, then every four years, to maintain the integrity of the zero carbon claim over time" (EDGE User Guide, Section 6.3: Advanced Certifications). Thus, the correct renewal schedule is initially after two years, then every four years (Option A).

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.
