Revised legislation carried on this site may not be fully up to date. At the current time any known changes or effects made by subsequent legislation have been applied to the text of the legislation you are viewing by the editorial team. Please see ‘Frequently Asked Questions’ for details regarding the timescales for which new effects are identified and recorded on this site.
1.—(1) An appliance shall be classified as A+ or A++ where the energy efficiency index alpha (I) is within the ranges specified in Table 1.U.K.
Energy efficiency index α(Iα) | “Energy efficiency class” |
---|---|
30 > Iα | A++ |
42 > Iα ≥ 30 | A+ |
Iα ≥ 42 | A to G (see below) |
(2) The energy efficiency index alpha shall be calculated using the formula:
where—
“AC” means the annual energy consumption of the appliance (in accordance with the harmonised standards); and
“SCα” means the standard annual energy consumption α of the appliance.
“SCα” is calculated as:
where—
“Vc” means the net volume (in litres) of the compartment (in accordance with the harmonised standards);
“Tc” is the design temperature (in °C) of the compartment;
the values of M and N are given in Table 2; and
the values of FF, CC, BI and CH are given in Table 3.
Type of appliance | Temperature of coldest compartment | Mα | Nα |
---|---|---|---|
(1) For these appliances, the temperature and star rating of the compartment with the lowest temperature will determine the values of M and N. Appliances with –18°C *(***) compartments shall be considered as fridge-freezers *(***). | |||
1. Larder Fridge | >-6°C | 0.233 | 245 |
2. Refrigerator/chillers | >-6°C | 0.233 | 245 |
3. Refrigerator no star | >-6°C | 0.233 | 245 |
4. Refrigerator* | ≤-6°C * | 0.643 | 191 |
5. Refrigerator** | ≤-12°C ** | 0.450 | 245 |
6. Refrigerator***/ | ≤-18°C ***/*(***) | 0.777 | 303 |
7. Fridge/freezer *(***) | ≤-18°C ***/*(***) | 0.777 | 303 |
8. Upright freezer | ≤-18°C *(***) | 0.539 | 315 |
9. Chest freezer | ≤-18°C *(***) | 0.472 | 286 |
10. Multi-door or other appliance | (1) | (1) |
Correction factor | Value | Conditions |
---|---|---|
(1) An appliance is “built-in” only if it is designed exclusively for installation within a kitchen cavity with a need of furniture finishings, and tested as such. | ||
FF (frost free) | 1.2 1 | For “frost free” (ventilated) frozen food compartments; Otherwise |
CC (climate class) | 1.2 1.1 1 | For “tropical” appliances; For “subtropical” appliances; Otherwise |
BI (built-in) | 1.2 1 | For built-in appliances (1) of under 58cm in width; Otherwise |
CH (chill compartment) | 50 Kwh/y 0 | For appliances with a chill compartment of at least 15 litres; Otherwise |
(3) If an appliance is not A+ or A++, it shall be classified in accordance with Part 2.
