Energy efficient commercial dishwashers save energy relative to less efficient dishwashers by using less hot water to wash wares and utensils. These savings are realized at the building water heater, and restaurants typically have gas water heaters.  Energy efficient high temperature machines also use less energy at the machine itself to heat water to sanitizing temperature (180F+), and utilize insulation and advanced controls to reduce idle energy consumption.  Energy savings for both low temperature (chemical sanitizing) and high temperature machines can also be realized by utilizing more efficient pumps.

The RTF's savings estimates use ENERGY STAR test data coupled with field data to estimate annual water and energy savings at the water heater as well as at the machine itself. Energy and water savings are calculated for ENERGY STAR V3.0 qualified machines against ENERGY STAR V2.0 which has been code in Washington and Oregon since 2021.

Decided 
October 24, 2012
RTF Meeting: October 24, 2012

Set measure to Out of Compliance

Decision Details

Adopt the SBW recommendations for the Commercial Cooking Equipment Energy Efficient Dishwasher measure and change the status to Out of Compliance with a sunset date of November 1, 2013.

RTF staff will work with stakeholders to develop a plan to bring the measure back into compliance with the Guidelines based on the recommendation memo and seek RTF approval of that plan by the sunset date. If a plan is not approved by the RTF by the sunset date, the measure will be deactivated.

Decided 
November 09, 2009
RTF Meeting: November 9, 2009

Approve measure update

Decision Details

Accept the savings with a weighted average calculated in four categories - fuel type (gas and electric) and high and low water temperature, all based on Energy Star data
