EDGE-Expert Dumps With Exact Questions and Answers

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.

Passive design features in EDGE focus on reducing energy demand through architectural and design strategies that minimize the need for active systems. The EDGE User Guide lists passive design measures included in its methodology: "Passive design features in EDGE include external shading, natural ventilation, insulation, and high-reflectivity materials, which reduce energy demand for heating, cooling, and lighting by leveraging climate and site conditions" (EDGE User Guide, Section 3.5: Passive Design Strategies). Option B, external shading, is explicitly mentioned as a passive design feature that reduces solar heat gain, thereby lowering cooling energy needs. Option A (lighting controls) is an active measure, not passive, as it involves electrical systems. Option C (renewable energy) is an energy generation measure, not a passive design strategy, as noted in the EDGE Methodology Report: "Renewable energy systems like solar PV are treated as energy supply measures, not passive design" (EDGE Methodology Report Version 2.0, Section 5.3: Energy Measures). Option D (efficient cooling system) is also an active system, not passive. Thus, external shading (Option B) is the correct passive design feature within EDGE’s calculation methodology.

EDGE Zero Carbon certification requires specific prerequisites and operational data to verify performance. The EDGE Certification Protocol details the requirements: "To apply for EDGE Zero Carbon certification, a project must first achieve EDGE Advanced certification, which requires at least 40% energy savings. Additionally, EDGE Zero Carbon certification mandates at least one year of operational data at 75% occupancy to confirm energy performance, after which carbon offsets can be purchased for the remaining energy use to achieve zero carbon status" (EDGE Certification Protocol, Section 2.3: Certification Levels). In this scenario, the building’s energy savings have increased to 60% with solar panels, qualifying it for EDGE Advanced (40% minimum). The next step is to gather one year of operational data before applying for EDGE Zero Carbon, making Option C (after achieving EDGE Advanced certification and gathering one year of operational data) correct. Option A (as soon as one year of operational data) skips the EDGE Advanced requirement: "EDGE Advanced is a prerequisite for EDGE Zero Carbon" (EDGE Certification Protocol, Section 2.3: Certification Levels). Option B (no wait time) is incorrect, as operational data is mandatory: "Operational data is required to verify performance for Zero Carbon certification" (EDGE User Guide, Section 6.3: Advanced Certifications). Option D (at the same time as EDGE Advanced and after two years) is wrong, as only one year of data is needed: "One year of operational data at 75% occupancy is sufficient for EDGE Zero Carbon" (EDGE Certification Protocol, Section 2.3: Certification Levels). Thus, Option C is the correct timeline.
