Replacement of Commercial Dishwashers
Commercial Equipment
Measure Goal
The goal of this document is to estimate the electricity savings triggered by the replacement of commercial dishwashers on a flat-rate basis.
Requirements
Only measures that meet the requirements of the Energy Ordinance (SR 730.01; EnV) can be credited. The additional requirements for the technical characteristics and for the implementation of the measure are set out in Table 1.
| Energy efficiency | The new dishwashers must not exceed the following electricity consumption values |
|---|---|
| Undercounter dishwashers, 400x400 mm basket (glasses) | |
| Undercounter dishwashers, 500x500 mm basket | |
| Undercounter dishwashers, 500x600 mm basket | |
| Pass-through dishwashers, hood for 1 basket | |
| Pass-through dishwashers, double hood for 2 baskets | |
| Re- soiling | The re-soiling performance of the new dishwashers must not exceed 3 particles/plate. |
| Hygiene | The new dishwashers must meet the hygiene requirements according to EN 17735:2022. |
Proof of compliance
Compliance with the requirements must be demonstrated by the following documents. The documents listed in Table 2 are an integral part of the proof of measure implementation.

Calculation Formulas
Creditable Electricity Savings
The creditable electricity savings result from the difference between the current and new annual electricity consumption, multiplied by the reduction factor (0.75) and the standard effective duration (15 years).
Annual Electricity Consumption
The annual electricity consumption is calculated from the product of the daily electricity consumption and 325 days per year.
Daily Electricity Consumption
The daily electricity consumption is calculated from the energy consumption for initial filling, the energy consumption per cycle, the number of cycles per day and the electrical power consumption in standby mode.
