COMMISSION DELEGATED REGULATION (EU) No 1254/2014

of 11 July 2014

supplementing Directive 2010/30/EU of the European Parliament and of the Council with regard to energy labelling of residential ventilation units

(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 of 19 May 2010 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 for the labelling of energy-related products. The delegated acts are to be adopted where products represent a significant potential for energy savings and present a wide disparity in performance levels although having an equivalent functionality and no other Union legislation or self-regulation is expected to achieve the policy objectives more quickly or at lesser expense than mandatory requirements. |
| --- | --- |

(1)

Directive 2010/30/EU requires the Commission to adopt delegated acts for the labelling of energy-related products. The delegated acts are to be adopted where products represent a significant potential for energy savings and present a wide disparity in performance levels although having an equivalent functionality and no other Union legislation or self-regulation is expected to achieve the policy objectives more quickly or at lesser expense than mandatory requirements.

| (2) | The Commission has assessed the technical, environmental and economic aspects of residential ventilation units. The assessment showed that the energy used by residential ventilation units accounts for a significant part of total household energy demand in the Union. Improvements have already been achieved in the energy efficiency of those products, but there is substantial scope for further reducing the energy consumption of such units. The assessment also confirmed a wide disparity in performance levels, and found no self-regulation or voluntary agreements which could achieve the policy objectives. |

The Commission has assessed the technical, environmental and economic aspects of residential ventilation units. The assessment showed that the energy used by residential ventilation units accounts for a significant part of total household energy demand in the Union. Improvements have already been achieved in the energy efficiency of those products, but there is substantial scope for further reducing the energy consumption of such units. The assessment also confirmed a wide disparity in performance levels, and found no self-regulation or voluntary agreements which could achieve the policy objectives.

| (3) | Small ventilation units with an electric power input of less than 30 W per air stream should be exempted from the scope of this Regulation. Those units are designed for many different applications, predominantly working intermittently and with supplementary functions only, for example in bathrooms. Including those ventilation units would represent a considerable administrative burden in terms of market surveillance due to large sales numbers, while contributing only to a small share of the energy saving potential. However, considering that they offer similar functionalities to other ventilation units, their possible inclusion should be similarly addressed in the review of this Regulation. Non-residential ventilation units (NRVUs) should be excluded from labelling as these products are chosen by planners and architects and largely independent from consumer and market behaviour. Ventilation units specifically designed to operate exclusively for emergency purposes or in exceptional or hazardous environments should also be exempted, as they are used rarely and for a short time. The exemptions also clarify that multifunctional units which predominantly heat or cool and kitchen range hoods are excluded. Harmonised provisions on labelling and standard product information regarding the specific energy consumption of residential ventilation units should be laid down in order to provide incentives for manufacturers to improve the energy efficiency of these units, encourage end-users to purchase energy-efficient products and contribute to the functioning of the internal market. |

ANNEX IX

Verification procedure for market surveillance purposes

For the purposes of checking conformity with the requirements laid down in Annex II, Member State authorities shall test a single RVU. If the measured values or values calculated on the basis of measured values do not match the manufacturer's declared values within the meaning of Article 3, subject to the tolerances in Table 1, measurements shall be carried out on three other units.

If the arithmetic mean of the measured values for these units does not meet the requirements, subject to the tolerances in Table 1, the model and all other equivalent models shall be considered not to comply with the requirements of Annex II.

The Member State authorities shall provide the test results and other relevant information to the authorities of the other Member States and to the Commission within one month of the decision being taken on the non-compliance of the model.

Member State authorities shall use the measurement and calculation methods in Annex VIII.

Table 1

| Parameter | Verification tolerances |
| --- | --- |
| SPI | The measured value shall be no more than 1,07 times the maximum declared value. |
| Thermal efficiency RVU | The measured value shall be no less than 0,93 times the minimum declared value. |
| Sound power level | The measured value shall be no more than the maximum declared value plus 2 dB. |

Parameter

Verification tolerances

SPI

The measured value shall be no more than 1,07 times the maximum declared value.

Thermal efficiency RVU

The measured value shall be no less than 0,93 times the minimum declared value.

Sound power level

The measured value shall be no more than the maximum declared value plus 2 dB.

The verification tolerances defined in this Annex relate only to the verification of the measured parameters by Member State authorities and shall not be used by the supplier as an allowed tolerance to establish values in the technical documentation. The values and classes on the label or in the (electronic) product fiche shall not be more favourable for the supplier than the values reported in the technical documentation.
