Key Findings

30% reduction — strongest NJ residential result

5100 Park Avenue achieved a 30% metered reduction on a 1-inch municipal supply — the highest single-property percentage reduction in the New Jersey multifamily portfolio.

Vacancy held below 2.5% — no occupancy distortion

The management company confirmed vacancy remained constant under 2.5% throughout both the pre- and post-installation measurement periods. This eliminates vacancy as a confounding variable in the savings calculation.

No central AC — savings are pure water efficiency

The property has no central air conditioning system, which means there are no cooling tower or evaporative cooling losses in the water system. The full 30% reduction reflects direct Smart Valve™ impact on domestic water consumption.

7-month payback on a 1-inch installation

At $0.0134/gal combined water and sewer, the $3,100/yr savings produced a 7 months return on investment — well within a single budget year.
