Description of the building:
A chain restaurant group has approximately 100 seats per store.
Retrofitted initiative:
Energy-saving Dishwasher with Heat Recovery System:
Replace the traditional dishwasher with an energy-saving dishwasher equipped with a heat recovery system. The heat recovery system efficiently captures waste heat generated during the dishwashing process and repurposes it to heat water from room temperature to 50-60 degrees Celsius.

Energy Consumption Assessment using Smart Wireless Power Sensor:
Following the replacement, an energy consumption assessment was conducted to compare the performance of the traditional dishwasher and the new energysaving dishwasher. Users can evaluate their actual energy saving and carbon footprint more accurately. The result demonstrated that new energy-saving dishwasher consume 16,600kWh less energy and reduce carbon emissions by 6,500 Co2 Kg per year.

Observed benefits other than energy saving:
- Water Saving: the new energy-saving dishwasher consume 1-1.5L water per rack comparing with traditional washer consume 2-2.5L water per rack.
- In-situ energy information of the energy-efficient dishwasher: Hong Kong does not have any energy labels for commercial dishwashers. Users can only know the power of the equipment, but different models of dishwashers have different energy efficiencies, therefore dishwashers with the same power may not necessarily mean they consume the same amount of electricity. Energy consumption assessment can help users evaluate an energyefficient dishwasher by measuring actual energy consumption.
- ESG reporting: Users may need to report environmental indicators or the performance of their energy-saving measures to the company or different stakeholders. For many catering industries, they do not have a suitable tool to evaluate the energy consumption of their kitchen equipment. Energy consumption assessment before and after replacing equipment can help users report their environmental performance to different stakeholders.
General observations of the retrofitting project:
Energy assessment using Smart Wireless Power Sensor is fast and requires no electrical work. Operations was not affected during the energy assessment.
