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.

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 green buildings 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.

In the CBCI EDGE curriculum, the EDGE Baseline is not fixed permanently because construction practices, typical system efficiencies, and national or city regulations evolve over time. To ensure that EDGE continues to represent a realistic and fair comparison against “standard practice” in each location, the EDGE Baseline is periodically reviewed and updated. The curriculum explains that baseline reviews are undertaken every 3 to 5 years when needed, and this review can include updates to the geographic coverage of EDGE, such as adding new countries or refining baselines where market conditions or codes have changed.

This review cycle helps maintain the credibility of the 20 percent savings thresholds by making sure the baseline remains aligned with what is commonly built in a given market. If baselines were updated too frequently, it would create instability for project planning; if updated too rarely, the baseline could become outdated and no longer reflect typical practice. The 3 to 5 year interval balances stability with relevance, ensuring that EDGE benchmarking stays accurate across different regions and over time.

Occupancy sensors in the EDGE software are part of energy efficiency measures aimed at reducing unnecessary energy use by automating system operation based on occupant presence. The EDGE User Guide explicitly defines their application: "Occupancy sensors in EDGE are used for controlling lighting in internal areas, automatically turning lights off when spaces are unoccupied to reduce energy consumption. This measure, often listed as EEM23 - Occupancy Sensors for Lighting, can achieve significant savings in buildings with intermittent occupancy, such as offices or schools" (EDGE User Guide, Section 4.4: Lighting Efficiency Measures). Option A, lighting, directly matches this description, as occupancy sensors are primarily associated with lighting control in EDGE. Option B (water taps) is incorrect, as occupancy sensors are not used for water systems in EDGE: "Water taps may be controlled by sensors in some projects, but this is not a recognized measure in EDGE, which focuses on measures like low-flow fixtures for water savings" (EDGE User Guide, Section 5.2: Water Efficiency Measures). Option C (air conditioners) is also incorrect, as occupancy sensors for HVAC are not a standard measure in EDGE: "While occupancy sensors can theoretically control air conditioners, EDGE does not include this as a measure; HVAC efficiency is addressed through measures like variable speed drives or efficient chillers" (EDGE Methodology Report Version 2.0, Section 5.1: Energy Efficiency Metrics). Option D (external lighting) is not applicable, as EDGE specifies occupancy sensors for internal areas: "Occupancy sensors in EDGE are applied to internal lighting, not external lighting, which may use timers or photocells instead" (EDGE User Guide, Section 4.4: Lighting Efficiency Measures). The EDGE Methodology Report further confirms: "The energy savings from occupancy sensors in EDGE are calculated based on reduced lighting hours in internal spaces, reflecting typical usage patterns in commercial buildings" (EDGE Methodology Report Version 2.0, Section 5.4: Lighting Calculations). Thus, occupancy sensors are used for controlling lighting (Option A).
