ANNEX IIU.K. Method for calculating the Energy Efficiency Index and the annual on-mode energy consumption
1.The Energy Efficiency Index (EEI) is calculated as EEI = P/Pref (A), where:U.K.
- Pref (A)
=
Pbasic + A × 4,3224 Watts/dm2,
- Pbasic
=
20 Watts for television sets with one tuner/receiver and no hard disc,
- Pbasic
=
24 Watts for television sets with hard disc(s),
- Pbasic
=
24 Watts for television sets with two or more tuners/receivers,
- Pbasic
=
28 Watts for television sets with hard disc(s) and two or more tuners/receivers,
- Pbasic
=
15 Watts for television monitors,
A is the visible screen area expressed in dm2,
P is the on-mode power consumption of the television in Watts measured in accordance with Annex VII, rounded to one decimal place.
2.The annual on-mode energy consumption E in kWh is calculated as E = 1,46 × P.U.K.
3.Televisions with automatic brightness controlU.K.
For the purposes of calculating the Energy Efficiency Index and the annual on-mode energy consumption referred to in points 1 and 2, the on-mode power consumption as established according to the procedure set out in Annex VII is reduced by 5 % if the following conditions are fulfilled when the television is placed on the market:
the luminance of the television in the home-mode or the on-mode condition as set by the supplier, is automatically reduced between an ambient light intensity of at least 20 lux and 0 lux;
the automatic brightness control is activated in the home-mode condition or the on-mode condition of the television as set by the supplier.
