Q3 & Q4 2024 · *Valve removed Sept 5, reinstalled Oct 25, 2024 — Q4 increase is removal-related, not performance-related
YYZ4 Q3 2024 shows 17.36% reduction. Q4 2024 shows a 14.44% usage increase — directly caused by valve removal on Sept 5 and not reinstalled until Oct 25, 2024. The Q3/Q4 average of 14.6% reflects this interruption.
Blue = YYZ3 · Teal = YYZ4 · Year-over-year vs Q3/Q4 2023 baseline
YYZ4 Q4 2024 shows a usage increase due to valve removal (Sept 5–Oct 25, 2024), not a performance failure.
Peak summer months (Jul–Sep) · Before: 2023 baseline · After: 2024 post-installation
Without the Smart Valve™, YYZ3 peaked at 1,107 m³/month. Post-installation the peak reduced to 457.30 m³ — a 58.69% reduction at the highest-use point in the year.
Q3/Q4 average · Source: AWS Measurement & Verification Report
YYZ3 shows a 2.52 gal/min reduction in average water flow over the 6-month post-installation period. At $3.00/m³, that sustained reduction drives thousands of dollars in avoided costs every month.
Year-over-year average · Contractual minimum = 15% · YYZ4 Q4 affected by valve removal
YYZ3 achieved 58.69% in Q3 2024 and 29.27% in Q4 2024 — a Q3/Q4 average of 43.98%, nearly three times the 15% contractual floor.
The valve was removed from YYZ4 on Sept 5, 2024 and not reinstalled until Oct 25, 2024. The 14.44% Q4 usage increase is a direct result of the site operating without the valve for most of Q4.
With the valve in place for all of Q3 2024, YYZ4 achieved a 17.36% year-over-year reduction — comfortably above the 15% guarantee. The technology performance was consistent across both facilities.
YYZ3's Q3 2024 result of 58.69% year-over-year reduction represents the highest independently verified single-quarter result in the Smart Valve™ portfolio.
YYZ3 shows a 2.52 gal/min reduction in average flow across Q3/Q4 2024 — from 5.26 to 2.74 gal/min. This is a structural reduction in water draw that translates directly to lower metered consumption.
Without Smart Valve™, YYZ3 peaked at 1,107 m³/month (Jul–Sep 2023). With Smart Valve™ installed, that peak dropped to 457.30 m³ — the most impactful savings occur exactly when water costs are highest.
All data is year-over-year quarterly comparison against Q3/Q4 2023 baseline. YYZ3 Q3 2024: 58.69% reduction. YYZ3 Q4 2024: 29.27% reduction. YYZ3 Q3/Q4 average: 43.98%. YYZ4 Q3 2024: 17.36% reduction. YYZ4 Q4 2024: 14.44% usage increase (valve removed Sept 5, reinstalled Oct 25). YYZ4 Q3/Q4 average: 14.6%. Smart Valve™ installed at both sites June 2024.
