# Commission Delegated Regulation (EU) 2015/1094 of 5 May 2015 supplementing Directive 2010/30/EU of the European Parliament and of the Council with regard to the energy labelling of professional refrigerated storage cabinets (Text with EEA relevance), Annex VIII: Method for calculating the energy efficiency index for professional refrigerated storage cabinets

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

For the calculation of the energy efficiency index (EEI) of a professional refrigerated storage cabinet model, the annual energy consumption of the cabinet shall be compared to its standard annual energy consumption.
The EEI shall be calculated as:
EEI = (AEC/SAEC) × 100
Where:
AEC = E24h × af × 365
AEC annual energy consumption of the cabinet in kWh/year
E24h energy consumption of the cabinet over 24 hours
af adjustment factor to be applied only for light-duty cabinets, according to Annex IX, point 2
SAEC = M × Vn + N
SAEC standard annual energy consumption of the cabinet in kWh/year
Vn net volume of the appliance, which is the sum of net volumes of all compartments of the cabinet, expressed in litres.
M and N are given in the Table 2.
