HOW IT WORKS

Go Green with Water savings

Case Study 1

WATERLOO 110-unit Students Housing

WATER COST
REDUCED TO
$2000/ month

95% of leaks
identified and fixed

COST $30k ROI 15 MONTHS

Problem:

The properties were experiencing relatively high-water consumption during periods of minimal occupancy that were the result of COVID occupancy restrictions and general seasonality with the academic year. Dollar impact was in excess of $4,000 per month for water and sewer charges for an empty building.

The problem was addressed in the short term when the water supply to the individual toilets was shut off. As this was a temporary fix, the building owner was looking for a way to identify when toilets were running and/or other high usage and/or leak events that were otherwise going undetected
and were no action was being taken.

Solution:

The final solution was to install in-line smart meters from Saya
Life www.saya.life on the cold-water feed to in turn provide;

•Shut-off capabilities
•Notification and diagnostic tool to pinpoint where leaks
and/or over usage were taking place
•Data collection for sharing with insurance provider

Case Study 2

Water budget of 3.4
gallons consumed per

evaporative cooling.

 

 

 

 

 

0.13 Gal/kWh saved, well below the project target of 3.4
Gal/kWh saved.

 

 

COST $50k ROI 24 MONTHS
The project team pursued a water budget of 3.4 gallons consumed per
kWh saved for using evaporative cooling. The Saya Life submetering
water data measures all HVAC units from a single meter located at the
main rooftop supply line as well as at each individual unit retrofitted with
DualCool. To calculate this metric, water and energy consumption for the
sub metered AHU 2 was collected for the months of July 2021 through
November 2021 and compared to similar baseline months in 2020. This
unit was under repair in June 2021 and that month was excluded from
the analysis.
The metric of gallons consumed per kWh saved regarding DualCool
retrofitted HVAC units was not forecasted for Q4 (December 2021 – May
2022) to yield an annual result. There was insufficient data to confidently
predict Gal/kWh Saved for the remaining six months of M&V. In lieu of
forecasted data for Q4 and Annual savings. The total water consumed by
AHU 2 between July and November 2021 was 2,423.2 gallons to save
18,053 kWh which resulted in a metric of 0.13 Gal/kWh saved, well
below the project target of 3.4 Gal/kWh saved.
System also monitors for anomalies and prevents water loss caused by
leaks.
