Taiwan publishes revised “Energy Efficiency Criteria and Labeling Methods” for desktop and laptop computers 
On July 8, 2021, Taiwan’s Bureau of Energy, Ministry of Economic Affairs published revised “Energy Efficiency Criteria and Labeling Methods” (note, standard for Taiwan’s energy label system) for desktop and laptop computers. The revised Standard will take effect on July 1, 2023. In addition, Taiwan’s Energy Label system is a voluntary energy efficiency certification (while Energy Efficiency Rating Labeling is a mandatory system). The outline of the revised standards is as follows.
Desktop computer
Application Scope
A personal computer that meets the definition of the national standard CNS 62623 “Desktop and notebook computers – Measurement of energy consumption”.
Energy consumption standard
The formula for calculating energy consumption standard has been revised as follows (unit: kWh/year).
8.76 (0.45 × POFF + 0.05 × PSLEEP + 0.15 × PLONG_IDLE + 0.35 × PSHORT_IDLE)
POFF: Average power output in shutdown mode (W)
PSLEEP: Average power output in sleep mode (W)
PLONG_IDLE: Average power output measured in long idle state (W)
PSHORT_IDLE: Average power output measured in short idle state (W)
Laptop computer
Application Scope
A personal computer that meets the definition of the national standard CNS 62623 “Desktop and notebook computers – Measurement of energy consumption”.
Energy consumption standard
The formula for calculating energy consumption standard has been revised as follows (unit: kWh/year).
8.76 × (0.25 × POFF + 0.35 × PSLEEP + 0.10 × PLONG_IDLE + 0.30 × PSHORT_IDLE)
POFF: Average power output in shutdown mode (W)
PSLEEP: Average power output in sleep mode (W)
PLONG_IDLE: Average power output measured in long idle state (W)
PSHORT_IDLE: Average power output measured in short idle state (W)
Validity period
In addition, in the public notice dated August 20, 2021, the provisions regarding the certificate validity period due to the transition between the old and new standards were specified as follows.
New application
- When the report based on both the current and revised standards is attached, the certificate is valid for 2 years.
- If only the report based on the current standards is attached, the certificate will be valid until June 30, 2023.
Extension application
- If the report based on the revised standard is attached, the certificate is valid for 2 years.
- If the report is not attached, the certificate is valid until June 30, 2023.
