Energy efficiency index
2.—(1) The EEI is determined as follows.
(2) For all household dishwasher models, the EEI is calculated by comparing the eco programme energy consumption at rated capacity (“EPEC”) of the dishwasher to its standard programme energy consumption (“SPEC”).
(3) The EEI must be rounded to one decimal place and is calculated as follows—
EEI = (EPEC/SPEC) × 100.
(4) For the purposes of sub-paragraph (3)—
(a)EPEC and SPEC are measured in kWh/cycle and rounded to three decimal places;
(b)SPEC is calculated as follows—
(i)for household dishwashers with rated capacity ps ≥ 10 and width > 50 cm—
SPEC = 0.025 × ps + 1.350;
(ii)for household dishwashers with rated capacity ps ≤ 9 or width ≤ 50 cm—
SPEC = 0.090 × ps + 0.450;
where ps is the number of place settings.
