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)

THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Directive 2010/30/EU of the European Parliament and of the Council on the indication by labelling and standard product information of the consumption of energy and other resources by energy-related products (1), and in particular Article 10 thereof,

Whereas:

(1) Directive 2010/30/EU requires the Commission to adopt delegated acts as regards the labelling of energy-related products that have significant potential for energy savings and exhibit wide disparity in performance levels with equivalent functionality.

(2) The energy consumed by professional refrigerated storage cabinets accounts for a significant share of total electricity demand in the Union, and professional refrigerated storage cabinets with equivalent functionality exhibit wide disparity in terms of energy efficiency. The scope for reducing their energy consumption is significant. Professional refrigerated storage cabinets should therefore be covered by energy labelling requirements.

(3) Harmonised provisions should be laid down on labelling and standard product information regarding the energy efficiency of professional refrigerated storage cabinets in order to provide incentives for manufacturers to improve the energy efficiency of those products, encourage end-users to purchase energy-efficient products and contribute to the functioning of the internal market.

(4) The combined effect of this Regulation and Commission Regulation (EU) 2015/1095 (2) is expected to result in estimated annual energy savings of about 1,8 TWh in 2020 and 4,1 TWh in 2030, corresponding to 0,7 and 1,4 million tonnes CO2 equivalent, as compared with what would happen if no measures were taken.

(5) The information provided on the label should be obtained through reliable, accurate and reproducible measurement procedures based on recognised state-of-the-art methods, including, where available, harmonised standards adopted by the European standardisation organisations, as listed in Annex I to Regulation (EU) No 1025/2012 of the European Parliament and of the Council (3).

(6) This Regulation should specify a uniform design and content of product labels for professional refrigerated storage cabinets.

(7) In addition, this Regulation should specify requirements for the product fiche and technical documentation for professional refrigerated storage cabinets.

(8) Moreover, this Regulation should specify requirements for the information to be provided in any form of distance-selling of professional refrigerated storage cabinets and in any advertisements and technical promotional material for such products.

(9) It is appropriate to provide for a review of the provisions of this Regulation taking into account technological progress,

HAS ADOPTED THIS REGULATION:

M and N are given in the Table 2. Table 2 M and N coefficient values Category Value for M Value for N Vertical Chilled 1,643 609 Vertical Frozen 4,928 1 472 Counter Chilled 2,555 1 790 Counter Frozen 5,840 2 380

ANNEX IX Measurement and calculation 1.

They shall meet the technical definitions, conditions, equations and parameters set out in this Annex. 2. For establishing the values of annual energy consumption and energy efficiency index for professional refrigerated storage cabinets, measurements shall be carried out under the following conditions: — The temperature of test packages shall be between – 1 °C and 5 °C for chilled cabinets and lower than – 15 °C for frozen cabinets. — The ambient conditions shall correspond to climate class 4 as detailed in Table 3, except for light-duty cabinets, which shall be tested in ambient conditions corresponding to climate class 3. Adjustment factors of 1,2 for light-duty cabinets at chilled operating temperature and 1,1 for light-duty cabinets at frozen operating temperature shall then be applied to the testing results obtained for light-duty cabinets. — Professional refrigerated storage cabinets shall be tested: — at chilled operating temperature in the case of a combined cabinet containing at least one compartment exclusively intended for chilled operating temperature, — at chilled operating temperature in the case of a professional refrigerated storage cabinet which has solely one compartment exclusively intended for chilled operating temperature, — at frozen operating temperature in all other cases. 3. The ambient conditions of climate classes 3, 4 and 5 are shown in Table 3.
