# Commission Delegated Regulation (EU) No 65/2014 of 1 October 2013 supplementing Directive 2010/30/EU of the European Parliament and of the Council with regard to the energy labelling of domestic ovens and range hoods (Text with EEA relevance), Division 2.1: Calculation of the Energy Efficiency Index (EEIhood)

Extent: E+W+S+N.I.

The Energy Efficiency Index (EEIhood ) is calculated as:
EEIhood=AEChoodSAEChood× 100and is rounded to the first decimal place.
Where:
SAEChood is the Standard Annual Energy consumption of the domestic range hood in kWh/a, rounded to the first decimal place,
AEChood is the Annual Energy Consumption of the domestic range hood in kWh/a, rounded to the first decimal place.
The Standard Annual Energy Consumption (SAEChood ) of a domestic range hood shall be calculated as:
SAEChood=0,55×WBEP+ WL+ 15,3Where:
WBEP is the electric power input of the domestic range hood at the best efficiency point, in Watt and rounded to the first decimal place,
WL is the nominal electric power input of the lighting system of the domestic range hood on the cooking surface, in Watt and rounded to the first decimal place.
The Annual Energy Consumption (AEChood ) of a domestic range hood is calculated as:
(i)for the fully automatic domestic range hoods:
AEChood=WBEP×tH×f+WL×tL60×1000+Po×1440−tH×f2×60×1000+Ps×1440−tH×f2×60×1000×365
(ii)for all other domestic range hoods:
AEC hood=WBEP×tH× f+ WL× tL60×1000× 365Where:
tL is the average lighting time per day, in minutes (tL = 120),
tH is the average running time per day for domestic range hoods, in minutes (tH = 60),
Po is the electric power input in off-mode of the domestic range hood, in Watt and rounded to the second decimal place,
Ps is the electric power input in standby mode of the domestic range hood, in Watt and rounded to the second decimal place,
f is the time increase factor, calculated and rounded to the first decimal place, as:
f=2−FDEhood× 3,6∕100
