Water consumption considerations.

Equipment that requires significant amounts of water—such as combi ovens, steamers and, most notably, warewashers—contributes heavily to your operating expenses and the water resources your kitchen consumes each day. Machines that are engineered specifically to conserve water not only reduce your water and sewage bills, but also save a considerable amount of the energy used to heat that water.

Hobart warewashers that surpass LEED benchmarks.
The benchmark for water usage by warewashers in the LEED for Schools is just 1.0 gallon per rack. The LXi undercounter, AM Select door-type and C-Line conveyor-type all best that mark. In addition, Hobart is well under the LEED for Retail commercial dishwasher requirements of 1.5 gallons per rack. In short, we have a warewasher that meets or beats LEED standards for every kitchen, no matter what the configuration.

Hobart's warewasher reduces process water consumption by 76% in University of Cincinnati's LEED®-certified recreation center.
pioneer in Leadership in Energy and Environmental Design (LEED®) certification, the University of Cincinnati was the first educational institution to produce a LEED-certified building in Ohio and currently has the most LEED-certified buildings of any educational institution in the state.

The recreation center was granted LEED for New Construction and Major Renovations certification based on five key areas of human and environmental health: sustainable site development, water savings, energy efficiency, materials selection and indoor environmental quality.

"The Campus Recreation Center received LEED credits for its use of recycled-content materials, a rainwater collection system, landscaping and a green outreach education panel," says Bob Marton, facilities and construction services project manager at the University of Cincinnati. "The recreation center achieved certification with a total of 29 points, including an innovation and design credit for kitchen process equipment water use reduction."

In order to achieve this innovation and design credit, the university had to maximize water efficiency within the recreation center by selecting equipment that is more energy and water efficient compared to typically chosen equipment. To qualify for this innovation and design credit, the university had to reduce water usage by at least 20%.

“Not only did we meet the 20% reduction, but we also far surpassed it,” explains Marton. “The university reduced water usage in the recreation center by 35%. In addition to simply using less water, this helps to lessen the burden on the municipal water supply and wastewater systems and reduces the carbon footprint from the kitchen equipment’s energy use.”

That 35% reduction equates to more than 515,000 gallons of water a year, not to mention the financial savings associated with purchasing and heating the water.

Hobart’s FT900 Warewasher played significant role in university’s water reduction.
The University of Cincinnati purchased a Hobart FT900 warewasher, with the Opti-Rinse™ technology, for CenterCourt, the recreation center’s 390-seat residential restaurant. Hobart’s FT900 played a significant role in the university’s sustainability efforts, contributing to 76% of the recreation center’s process water reduction.

“Using the Hobart FT900 with Opti-Rinse, the recreation center experienced an estimated annual energy and water savings of approximately $7,700 and almost 400,000 gallons of potable water,” says Marton.

Hobart’s FT900 Dual-Rinse Flight-Type warewasher is engineered to reduce water use and energy consumption while maintaining all NSF standards for cleaning and sanitizing. The Opti-Rinse feature uses far less water but generates larger water droplets, resulting in more efficient heat transfer.

In addition to using the Hobart FT900 warewasher, the University of Cincinnati also relied on energy-efficient flow fixtures, ice machines and ENERGY STAR® qualified Traulsen refrigerators and freezers to reduce water consumption and energy costs.
