Office Buildings Save Water Costs
Office Buildings Post YOY Savings in excess of 20%
A third party engineering review of the data from two Hartman REIT buildings in Houston show that “the Smart Water Valve performed as predicted and enabled the properties to achieve monetary savings in excess of 20% as evidenced by the City of Houston utility bills based upon meter readings of City Meters.”

Performance Engineer Review
Dear Mr. Crockett: We are pleased to conduct our third-party engineering services to provide an independent assessment of the Smart Water Valve effectiveness in reducing a-property's monthly water (and related sewer) utility expenses. Reihl Engineering, LLC was engaged to review the data and attest to the validity of the testing methodology and results on-three valves that were installed in two Hartman REIT buildings in Houston, Texas. The plumbing configurations included: A 4" and 6” valve installed on a line supplying a house tank at two properties and a 2" installed on an irrigation system line directly dependent upon the city's water pressure for its operation.
The valve is installed on the downstream side of the water meter. It reduces the pressure drop across the meter; thus, keeping entrained gas in a dissolved mode (limiting its volume) as the water passes through the meter - so that a volumetric meter more accurately measures the actual water usage. ln some installation configurations, such as when the volume of water or psi is reduced at its final point of use, the valve will also reduce the actual amount of water used. Because the valve is adjustable, it may be very easily adjusted by the building engineer in-situ if conditions unexpectedly change.
Data reviewed: manufacturer's information; monthly comparisons to the previous year's data of dollars spent, gallons used and gallons used per day - both before and after each valve was installed; summary spreadsheets; and an affirmation by the Houston area property engineer that the buildings had no significant changes in operation, occupancy, leaks or drain-downs that could skew the results in the favor of the valve.
Based an my review of this information, it is my professional opinion that the Smart Water Valve performed as predicted and enabled the properties to achieve monetary savings in excess of 20% as evidenced by the City of Houston utility bills based upon meter readings of City Meters.
