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.

The baseline assumptions in EDGE software, known as the Base Case, are critical for calculating resource savings and are determined using standardized data. The EDGE Methodology Report explains: "Baseline assumptions in EDGE, referred to as the Base Case, are determined by market surveys of typical construction practices in the project's country, reflecting common materials, systems, and design practices for the selected typology and location" (EDGE Methodology Report Version 2.0, Section 3.1: Base Case Determination).
Option C, market survey of typical construction practices, aligns with this methodology. Option A (EDGE software users) is incorrect, as users do not set the baseline; they input project-specific data. Option B (EDGE Auditors) is also incorrect, as auditors verify compliance, not establish baselines. Option D (market survey of best construction practices) is wrong because EDGE uses typical practices, not best practices, to create a realistic benchmark, as clarified in the EDGE User Guide: "The Base Case reflects typical local practices, not best practices, to ensure a fair comparison for resource savings" (EDGE User Guide, Section 2.3: Using the EDGE App).
Reference:EDGE Methodology Report Version 2.0, Section 3.1: Base Case Determination; EDGE User Guide Version 2.1, Section 2.3: Using the EDGE App.

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).

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.

The CBCI EDGE curriculum explains that EDGE uses a simplified, quasi-steady-state approach to estimate building energy performance. To keep the method practical and consistent across many countries, EDGE relies on climate datasets that represent typical conditions over longer time steps rather than detailed hour-by- hour weather files used in dynamic simulation tools. In EDGE, the local climate inputs applied in the baseline and improved case calculations are based on monthly climate averages, including outdoor minimum and maximum temperatures, humidity, wind conditions, and solar radiation.
Monthly averages provide an effective balance between accuracy and usability. They capture seasonal variation that strongly influences heating and cooling loads, while avoiding the complexity and data intensity of hourly modeling. Weekly averages are not used because they add complexity without providing the standardized global consistency that EDGE aims for. Annual averages would be too coarse, because they would hide seasonal peaks and understate the impact of envelope and HVAC efficiency measures.
Therefore, the correct statement is that EDGE calculations use monthly average climate information for the key weather parameters listed.
