Case studies

Verified where it counts: the utility bill

Every figure below comes from an independent study with control equipment or third-party verification. Figures from independent lab and field studies; results vary by system age, load profile, and operating conditions.

32–43%

improvement in kW/ΔT

W Hotel Lakeshore, Chicago

200-ton chiller · 2 years

32–43% improvement in kW/ΔT, statistically significant at p < 0.0001.

Why it matters: Longest field study, run with a simultaneous control compressor. Savings grew over time.

20.1%

sustained reduction at one year

Large hotel complex, Dallas

40-ton units · 1 year

20.7% reduction at pilot; 20.1% sustained at one year.

Why it matters: Side-by-side identical units serving the same space. Savings were consistent and durable.

22%

daily kWh reduction

Data center CRAC units

22-ton CRAC units

22% daily kWh reduction.

Why it matters: Verified by a licensed PE/CMVP with 1-minute interval logging and a control unit.

32%

kWh savings (temperature-normalized)

Westin Jersey City

15-ton rooftop unit

32% kWh savings, temperature-normalized.

Why it matters: Cross-validated via two independent methods, both converging at 32%.

Laboratory baseline

It starts in the lab

Lab numbers are the floor, not the ceiling — accumulated wear and variable loads make real-world savings materially higher.

+6% SEER

cooling capacity +7–13% vs. R-134a

ARL laboratory test

AHRI 210/240 standard

Lab baseline; real-world savings are materially higher due to accumulated wear and variable loads.

+9% to +43%

EER improvement

ARL multi-refrigerant comparison

Five refrigerant families

Consistent across R-22, R-404A, R-407C, R-438A, and R-427A.
