SCHEDULE 5ENERGY EFFICIENCY CLASS
1.—(1) The energy efficiency class of an appliance shall be determined in accordance with Table 1 where—
“energy efficiency index” (expressed as a percentage) = annual energy consumption of appliance in accordance with note V to Figure 1 in Schedule 1 (the label)/standard annual energy consumption of appliance;
“standard annual energy consumption of appliance” (expressed in kWh/year) = M × adjusted net volume + N;
“adjusted net volume” (expressed in litres) = net volume of fresh food compartment + Ω × net volume of frozen food compartment; and
the values of M, N and Ω are taken from Table 2.
TABLE 1
Energy efficiency index: I | Energy efficiency class |
---|---|
I < 55 | A |
55 ≤ I <75 | B |
75 ≤ I < 90 | C |
90 ≤ I < 100 | D |
100 ≤ I < 110 | E |
110 ≤ I < 125 | F |
125 ≤ I | G |

Notes to Table 2 (1) For refrigerator/cellars the adjusted volume = net volume of fresh food compartment + Ω × net volume of cellar (10°C) compartment (expressed in litres). (2) For “no frost” appliances as defined in paragraph 1(12) of Schedule 2 (the information notice), this index is increased by a provisional factor of 1.2, giving a value of 2.58. (This allows for the possible bias of the measurement method, which does not allow for the lack of ice build-up on “no frost” appliances. In practice, ice build-up will somewhat increase the consumption of “conventional” appliances.) (3) Adjusted net volume (AV) shall be calculated by the formula:
(4) For these appliances the values of M and N shall be determined by the temperature and star rating of the compartment with the lowest temperature, in accordance with Table 3: | |||
