Hotel Water Retrofit
A familiar brand of hotels had been working with STS to develop various energy and cost savings measures to shore up their building envelop, reduce costs, and improve the occupancy experience. Through an investment grade audit, the STS team determined there was potential for significant savings by applying one of the lowest cost, higher reward solutions offered. With a focus on solutions that have a quick payback, this hotel was interested in any solution that had a return on investment of 3 years or less. They turned to the STS team to design and implement a solution that would reduce the monthly water and sewer costs that had continued to rise year after year due to increased tariffs.
STS introduced The Flow Management System. The Flow Management System maintains a pressurized column of water past the water meter that prevents the pressure drop caused by user demand from reaching the water meter, therefore preventing air volume from increasing at the meter. It eliminates turbulence and over-spinning of the meter caused by surges and the sudden on and offs of typical water demand. It keeps the flow rate within the range the meter was designed to.
This hotel needed a partner that could identify many different types of solutions beyond the traditional efficiency solutions.
A strategy was created by STS to install a valve before the hotel water meter that would eliminate the turbulation of air in the water pipe. This design would reduce the monthly water measurement.
•$52k in annual savings
•ROI of 13 months
•Ability to report reduced water usage
With the significant annual savings realized from the water project, this organization decided to move forward with implementing this water solution to their other properties.
