2 1. WHAT IS THIS CONSULTATION ABOUT? Possible mandatory requirements for non-household refrigerated storage s, including: Mandatory minimum energy efficiency requirements for placing on the EU market (CEmarking) see section 4.1 below Mandatory energy labelling requirements (A-G classes) see section 4.2 below. 2. BASIC RATIONALE BEHIND THE PROPOSAL The market is largely driven by price and poor performing s can be produced at low cost. Also well-designed s achieving significant energy savings are available, but it is hard for suppliers to differentiate their products and justify any price premium. Hence it is proposed to eliminate least energy efficient products through gradually rising mandatory minimum requirements and at the same time encourage sales of more energy efficient equipment through mandatory energy labels. 3. SCOPE OF THE ENVISAGED REQUIREMENTS A non-household refrigerated storage is defined as: An insulated integrating at least one condensing unit and one or more compartments accessible via one or more doors and/or drawers, intended for the storage but not the display and sale of refrigerated or frozen foodstuffs and intended for non-household purposes. It is cooled by one or more energy-consuming processes. This includes the following categories: Category VC: Vertical chilled s Category VF: Vertical freezer s Category HC: Counter, horizontal and under-counter chilled s Category HF: Counter, horizontal and under-counter freezer s Category FF: Fridge freezer s Category CHEST: Non-household chest freezers. Page 2 of June 2012

3 It is envisaged that the same requirements may be applied to storage s with transparent doors (which are intended for the storage, but not the sale and display of foodstuff, and are therefore usually located in storage areas, back shops, professional kitchens etc and not in retail areas). See Questionnaire. Excluded from the scope (see Questionnaire). Cabinets operating with a remote condensing unit Open s Open top preparation tables and saladettes Cabinets that carry out food processing and not just storage function (e.g. bakery s that chill, heat and humidify) Serve-over counters and any other form of primarily intended for display and sale of foodstuff. Notes on special provisions and exemptions Semi-professional s (not designed for climate class 4 conditions) may be made subject to standard testing and requirements, or may be considered for testing at climate class 3 conditions with calculated adjustment of energy consumption to simulate climate class 4 conditions for use in a comparable energy label and minimum requirements. See Questionnaire. Built-in, roll in and roll-through s and fridge freezers may be exempted until review of the regulation due to inadequate data to set standards at present. See Questionnaire. Non-household static air s under consideration to be subject to the labelling and minimum energy efficiency requirements of household refrigerators from January See Questionnaire Non-household chest freezer s proposed to be subject to the labelling and minimum energy efficiency requirements of household refrigerators from July See Questionnaire. Storage s fitted with transparent doors are under consideration for exclusion from these regulations (and inclusion with Lot 12 display s in due course), or possible inclusion with storage s under certain special provisions. See Questionnaire. Heavy duty s (defined as those that can meet temperature requirements under climate class 5 conditions) are proposed to be subject to the same requirements of performance and testing as standard s but are under consideration for possible exemption from Tier 2 and/or Tier 3 requirements. See Questionnaire. Under-counter s are under consideration for inclusion along with other horizontal s, despite their more challenging usage conditions from an energy efficiency perspective. This is because of the principle that users should be made aware of any higher consumption of such s at the point of purchase via a comparable energy label, and that such s could be designed to meet the minimum requirements without excessive cost. See Questionnaire. Please see precise definitions of all these specific types of s in section 10. Page 3 of June 2012

4 4. ENVISAGED REGULATORY REQUIREMENTS 4.1 PROPOSED ECODESIGN REQUIREMENTS FOR CATEGORIES VC, VF, HC AND HF Requirements Date of entry into application ENERGY EFFICIENCY INDEX (EEI) Comment Tier 1 1 year after legal entry into force (January 2015) EEI < 125 = Phase out of Class G Tier 2 2 years after legal entry into force (January 2016) EEI < 110 = Phase out of Class F Tier 3 4 years after legal entry into force (January 2018) EEI < 100 = Phase out of Class E NB. This may be applied equally to models with transparent doors See Questionnaire. Page 4 of June 2012

5 4.2 PROPOSED ENERGY LABELS All non-household storage s falling in the scope of the definition above must have a designated EU energy label from July The energy label A-G will be broadly similar in size and format to the usual EU household appliance energy label. Additional classes (A+, A++, A+++) above class A would be introduced in subsequent years, and lowest classes are removed so that the label retains no more than 7 label classes (please see pictures and explanations in Annex 1). Suppliers shall provide a printed energy label with each in accordance with the regulation and publicly accessible information about the energy labelling class of each. Dealers (and/or suppliers where appropriate) shall ensure that storage s are always presented with the right energy label at the point of sale. The energy class of the model has to be included in catalogues or any other promotional material describing the technical features of the product, as well as in advertisement including energyrelated and price information. FOR CATEGORIES HC, HF, VC AND VF Energy label class EEI Start date for mandatory inclusion on labels (Note: Classes are allowed to be displayed before this date) Date from which class shall not appear on labels (Note: Classes are allowed to be omitted before this date) A+++ EEI < 18 January A++ 18 < EEI < 28 January A+ 28 < EEI < 40 January A 40 < EEI < 55 July B 55 < EEI < 75 July C 75 < EEI < 90 July D 90 < EEI < 100 July E 100 < EEI < 110 July 2014 January 2018 F 110 < EEI < 125 July 2014 January 2016 G EEI > 125 July 2014 January CALCULATION AND MEASUREMENT 5.1 CALCULATION OF THE ENERGY EFFICIENCY INDEX (EEI) The EEI is the ratio between the Annual Energy Consumption of the specific model (usually measured through testing) and a Standard Annual Energy Consumption calculated from a formula using the volume of the specific (see below). EEI is expressed as a percentage. EEI AEC 100 SAEC Where AEC=E 24h 365 With AEC = Annual Energy Consumption of the in kwh/year Page 5 of June 2012

6 E 24h = energy consumption of the over 24 hours And SAEC= M V n +N With SAEC = Standard Annual Energy Consumption of the in kwh/year Vn = net volume of the appliance, which is the sum of net volumes of all compartments of the. The net volume is defined as the volume containing foodstuffs within the load limit, minus the volume of shelves and any internal fittings. It is measured as indicated in standard EN For fridge freezers (if they are included), the net volume is replaced by the adjusted net volume Where V A = V n,ref + V n,frz 1.92 V n,ref is the sum of the net volume of all chilled compartments in litres V n,frz is the sum of the net volumes of all freezer compartments in litres The factor 1.92 is from a standard thermodynamic ratio which provides the volume of refrigerator compartment that consumes the same energy as a unit volume of the freezer compartment. It is calculated from the equation: (30 (-18)) / (30 5) In which the ambient temperature is 30 C, the average freezer compartment temperature during test is - 18 C and the average freezer compartment temperature during test is +5 C. M and N are given in the table below derived from analysis of the available EU data. Category Value for M Value for N Vertical Chilled (VC) Vertical Frozen (VF) Horizontal, counter and under-counter Chilled (HC) Horizontal, counter and under-counter Frozen (HF) Note: Values would have been given for fridge-freezers but insufficient evidence is available at present to set robust requirements. This is under review. 5.2 WHAT IS THE TEST METHOD FOR MEASURING ENERGY CONSUMPTION? The test methodology will be published by the end of 2013 at the latest. The envisaged requirements have been developed on the expectation that the final measurement method from the European Standardisation Organisations (CEN TC44 Working Group 2) will be based on EN ISO : See section 3.7 of EN 441 1: EN 441 has been superseded, but the replacement (EN23953) does not provide an adequate definition for net volume the purpose of this regulation. Page 6 of June 2012

7 with amendments similar to the CECED Italia proposed methodology 2, and with a much improved and clarified net volume calculation. At least the following parameters that directly influence the energy consumption results have to be defined in advance: i. The storage temperatures for the test are M1 (chilled) or L1 (frozen) ii. iii. iv. The ambient conditions of test to be Climate Class 4 (+30 C and 55% relative humidity) The appliance is loaded as indicated in EN23953 (i.e. positioning of the M-packages inside the during the test) The test has a 48-hour duration v. The door opening protocol is performed as indicated in the CECED Italia methodology 3 : Door opening scheme for all chilled s (and counter freezers): Door opened for 2 minutes Each door opened for 6 sec, 6 times per hour, for a total of 12 hours Doors closed for 12 hours (less 2 mins) Door opening scheme for vertical freezer s: Door opened for 1 minute Each door opened for 6 sec, 6 times per hour, for a total of 4 hours Doors closed for 4 hours First two steps repeated Doors closed for 12 hours (less 2 min) vi. The net volume is defined as the volume containing foodstuffs within the load limit, minus the volume of shelves and any internal fittings. Note: The method for measuring the net volume is to be fully defined by CEN TC44 WG2. The method contained in EN23953 is not considered adequate for the purpose of the future regulations which crucially depend upon a fair system for assessing internal net volume. In contrast, efficiency of display s for EN23953 was based upon total display area, TDA, which was fully developed in that standard but not calculation of volume. In the event that the required harmonised test method would not be adopted (i.e. voted for) when the regulation enters into force, the Commission would publish a transitional test method on the basis of the above mentioned elements. If the energy consumption of a with drawers is tested (and not calculated or extrapolated from test results obtained for an equivalent model with doors), the testing will follow the same opening protocol as that for doors. 2 The CECED Italia methodology is available from 3 The CECED Italia methodology is available from Page 7 of June 2012

8 6. WHAT SHALL BE DECLARED WHEN PLACING THE PRODUCT ON THE EU MARKET? From 1 July 2014, the following parameters shall be reported in the product documentation: The intended use for storage (not display) of foodstuff the declared category of the appliance according to the definitions of this regulation (e.g. horizontal chilled, roll-in freezer, static air, semi-professional, heavy duty etc.). Indication of any restriction on the product s intended usage (e.g. semi-professional s are not appropriate for use in hot kitchens) Net storage volume in litres and rounded to one decimal place. For refrigerator-freezer models, the chilled net volume, the freezer net volume and the adjusted net volume shall be declared in litres Declared annual energy consumption in kwh per year to the nearest whole unit Declared Energy Efficiency Index and associated energy label class Explanation for users of how to minimise the energy consumption of the The manufacturer s technical documentation file shall include: i. The intended use for storage (not display) of foodstuff ii. A general description of the model, sufficient for it to be uniquely and easily identified, including the declared category of the model according to the definitions of this regulation (e.g. horizontal chilled, roll-in freezer, static air, semi-professional, heavy duty etc. as appropriate) iii. Any reports of relevant measurement tests with rating conditions for test (storage temperature(s), climate class or ambient temperature and humidity during test). iv. Net storage volume in litres and rounded to one decimal place. For refrigerator-freezer models, the chilled net volume, the freezer net volume and the adjusted net volume shall be declared in litres v. Declared annual energy consumption in kwh per year to the nearest whole unit vi. Declared Energy Efficiency Index and associated energy label class vii. Where the information relating to a particular has been obtained by calculation on the basis of design, and/or extrapolation from other s, the documentation should include details of such calculations and/or extrapolations, and of tests undertaken to verify the accuracy of the calculations undertaken (details of any mathematical model and of measurements taken to verify this model). And also the appropriate test method, climate class and storage temperature used as the basis for calculating or otherwise estimating the declared energy consumption 7. REVIEW OF THE REGULATION The envisaged requirements will have to be reviewed by the European Commission depending on technological progress and not later than 4 years after its entry into force, which coincides with the introduction of Tier 3 (January 2018).

9 8. FORMAT OF ENERGY LABELS It is expected that the layout / format of the future label will be very similar to that of household refrigerators (see picture 1 below, this is the label currently in use). However, the label for non household storage s is expected to be A-G scale Picture 1 All non-household storage s will have to have an EU energy label from July At the beginning, the energy classes will range from A (the most energy efficient) to G (the least energy efficient). Following the entry into force of new requirement, the lowest classes will be removed, and additional ones (A+, A++, A+++) will be added. The label will always retain no more than 7 label classes. The pictures 2 and 3 below, which refer to the energy labelling of televisions, represent how the process works. In this example, the one on the left has come into force in 2011, and the second one will substitute it in 2014, as the requirements become more stringent and the lowest class, G, will be removed from the market. This process will be repeated: in 2017 class A++ will be introduced and class F removed. Manufacturers will be allowed to use labels with additional classes in advance, if they already have products complying with A+, A++ or A+++ before these classes become mandatory. Pictures 2 and 3 Page 9 of June 2012

10 First TV Energy label, in use since 2011 Second TV Energy label, in use from 2014 The following information shall be included in the label: I. supplier's name or trade mark; II. supplier's model identifier, meaning the specific code which distinguishes a non-household refrigerated model from other models with the same trade mark or supplier s name; III. IV. the energy efficiency class; Annual energy consumption (AEC) in kwh/year, rounded up to the nearest integer; V. declaration of the category which the belongs to (e.g. vertical chilled ) Page 10 of June 2012

11 9. GRAPHS SHOWING THE DISTRIBUTION OF KNOWN PRODUCT DATA ACROSS THE PROPOSED EU ENERGY LABEL CLASSES These scatter plots show the energy consumption and net internal volume of a range of products made available to the European Commission in preparing these proposals. The majority of data were provided the national trade association of a major EU producer country and are estimated to be representative of the products on several of the largest EU national markets. It also includes data from two schemes run by national governments to promote more efficient products and is supplemented by data from two individual manufacturers. These graphs show all of the available EU data and the thresholds proposed for labels for each category of. In addition, graphs 5 and 6 show the distribution of products in the CECED Italia data set across the CECED Italia energy label classes (including duplicate entries in the data set). Whilst this does not correspond exactly with the proposed EU labels and also does not include the UK, Danish and other EU supplier data, it does serve to show the distribution of performance levels for the majority of the available EU data. The data were normalized to render them comparable before plotting on these graphs. The approach to cleaning of the data sets and normalisation of the data is explained in the document Normalisation methodology used for the product performance data. Further details of the mathematical model for s which underpinned the normalization process is given in the Report on mathematical modelling to support the data normalisation process (report by CLASP).

DEFINITIONS The following definitions are proposed for use in the regulation: Built-in refrigerated Cabinet with an integral condensing unit A fixed non-household refrigerating appliance intended to be installed in a, in a prepared recess in a wall or similar location and requiring furniture finishing. It is therefore sold without external enclosure and designed exclusively to be mounted inside a separately available enclosure or furniture item. A with integrated condensing unit that simply requires electrical power supply to function. (Contrary to with remote condensing unit) Page 14 of June 2012

15 Chest freezer Chilled Counter Freezer Heavy duty refrigerated Horizontal Multi-use Open Refrigerated bench Refrigerated preparation top Roll-in refrigerated Roll-through refrigerated Saladette Refrigeratorfreezer Semiprofessional or light duty refrigerated Static air A food freezer in which the compartment(s) is accessible from the top of the appliance or which has both top-opening type and upright type compartments but where the gross volume of the top-opening type compartment(s) exceeds 75% of the total gross volume of the appliance. A refrigerated intended to store and maintain foodstuff at a temperature above 0 C, with reference point at +5 C (M1 temperature class) A refrigerated with one or more doors (or drawer fronts) in the vertical plane including a top surface designed as a worktop with a height of less than 1200 mm and generally with a height over 865 mm. A refrigerated intended to store and maintain foodstuff at frozen temperatures below -15 C, with reference point at -18 C (L1 temperature class) A refrigerated that can achieve the relevant temperature requirements of testing under Climate Class 5 conditions. A refrigerated with one or more doors (or drawer fronts) in the vertical plane and a height of less than 1200mm. Includes counter, under-counter and wallmounted s. A refrigerating appliance that has one or more compartments that can be set for use at chilled or frozen temperatures by choice of the end-user A for which some or all of the stored contents are accessible without opening a door or drawer. See counter. A refrigerated enclosure for chilling of easy-access temporary storage bins, for example for pizza toppings and salad items. A refrigerating appliance with at least one chilled storage compartment and at least one other freezer storage compartment. A refrigerated designed so that a trolley of foodstuff can easily be rolled into or out of it when the door is open. A roll-in refrigerated with door(s) on opposite faces of the for access from both sides. A refrigerated with one or more doors (or drawer fronts) in the vertical plane but having cut-outs in the top surface into which temporary storage bins can be inserted, for example for easy-access storage of pizza toppings, salad items etc. The cut outs adversely impact insulation properties. A professional refrigerated designed for operation in Climate Class 3 conditions and so not suitable for use in the warm and humid conditions combined with high door/drawer usage associated with commercial cooking areas. A refrigerated without internal forced-air circulation. Most often applicable Page 15 of June 2012

16 refrigerated Under-counter Vertical to avoid the drying effect associated with conventional forced-air s. Usually achieved through the absence of any of internal fans. These products are not generally capable of achieving the necessary temperature requirements for professional refrigerated s. A refrigerated with one or more doors (or drawer fronts) in the vertical plane and designed for placing under a separate counter, worktop or other furniture, generally (but not exclusively) between 830mm and 900mm high. A refrigerated with one or more doors (or drawer fronts) in the vertical plane and a height of over 1200mm. Includes chilled, freezer and fridge-freezer types. Includes single and multiple door or drawer. 11.
