EDGE-Expert EDGE Excellence in Design for Greater Efficiencies (EDGE Expert) Exam Free Practice Exam Questions (2025 Updated)

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.
