of XXX 
supplementing Directive 2010/30/EU of the Eu ropean 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 Eu ropean Parliament and of the Council of 19 
May 2010 on the indication by labelling and stan dard 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 Commi ssion to adopt delegated acts for the 
labelling of energy-related products. The de legated acts are to be adopted where 
products represent a significant potential for energy savings and present a wide 
disparity in performance levels although ha ving an equivalent functionality and no 
other Union legislation or se lf-regulation is expected to  achieve the policy objectives 
more quickly or at lesser expens e 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 fo r further reducing the 
energy consumption of such units. The assessm ent also confirmed a wide disparity in 
performance levels, and found no self-regula tion or voluntary agreements which could 
achieve the policy objectives.  
(3) Small ventilation units whic h have a single fan and a nominal power input smaller 
than 30 W should be exempted from the sc ope of this Regulation. Those units are 
designed for many different applications, predominantly working intermittingly and with supplementary functions only, for example in bathrooms. Including those 
ventilation units would repr esent a considerable admini strative burden in terms of 
market surveillance due to large sales numbers, while contributing only to a small share of the energy saving potential. Non-re sidential 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 exclusivel y for emergency purposes  or in exceptional 
or hazardous environments should also be exempted, as they are used rarely and for a short time. However, as they offer functiona lities similar to those of other ventilation 
units, they should be taken into considerat ion again when the measure is reviewed.  
                                                
 
1 OJ L 153, 18.6.2010, p. 13.  
EN 2   EN (4) Harmonised provisions on labelling and sta ndard product informa tion regarding the 
specific energy consumption of residential ventilation units shoul d be laid down in 
order to provide incentives fo r 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. 
(5)
 As the sound power level of a residentia l ventilation unit can be an important 
consideration for consumers, information on this should be included on the label. 
(6) The combined effect of this Regulati on and Commission Regulation (EU) No … of 
…2 is expected to raise the aggregated saving by 1  300 PJ (45  %) to 4  130 PJ in 2025. 
(7) The information provided on the label should  be obtained through reliable, accurate 
and reproducible methods s which take into  account recognised ‘s tate of the art’ 
measurement and calculation methods, , in cluding, where avai lable, harmonised 
standards adopted by the European standa rdisation bodies in accordance with the 
procedures laid down in Regulation (EU)  No 1025/2012 of the European Parliament 
and of the Council3,  
(8) This Regulation should specify requirements  as to the uniform design and content for 
the label, the technical docum entation and the fiche. Requirements should also be laid 
down as regards the information to be provi ded in the case of a ny form of distance 
selling, advertisements and technical promotional materials for ventilation units, as the importance of information displayed to end-users via the internet is increasing.

Measurements and calculations 
1. The specific energy consumption (SEC) is  calculated using the following equation: 
SEC= ta· pef· q net·MISC·CTRLx·SPI –  
th·ΔTh·ηh-1·cair· (q ref – q net·CTRL·MISC·(1- ηt))+Q defr  
where 
– SEC is the specific energy consumption for ve ntilation per m² heat ed floor area of a 
dwelling or building [kWh/m².a]; 
– ta is annual operating hours [h/a]; 
– pef is the primary energy factor for electri c power generation a nd distribution [-]; 
– qnet is net ventilation rate demand per m² heated floor area [m³/h.m²]; 
– MISC  is an aggregated genera l typology factor, incorporat ing factors for ventilation 
effectiveness, duct leakage and extra infiltration [-]; 
– CTRL is the ventilation control factor [-]; 
– x is an exponent that ta kes into account non-linearit y between thermal energy and 
electricity saving, depending on moto r and drive characteristics [-]; 
– SPI is specific power input [kW/(m³/h)]; 
– th is total hours heating season [h]; 
– ΔTh is the average difference in indoor (19  °C) and outdoor temperature over a 
heating season, minus 3K correction for solar and internal gains [K]; 
– ηh is the average space heating efficiency [-]; 
– cair is the specific heat capacity of air at c onstant pressure and density [kWh/(m³ K)] 
– qref is the reference natural ventilation rate per m² heated floor area [m³/h.m²]; 
– ηt is the thermal  efficiency of heat recovery [-]; 
– Qdefr is the annual heatin g energy per m² heated floor area [kWh/m².a] for defrosting, 
based on a variable electric resistance heating. 
Qdefr= tdefr·Δtdefr·cair·qnet·pef , 
 
where 
– tdefr is the duration of the defrosting period, i.e. when the outdoor temperature is 
below -4  °C [h/a], and 
– Δtdefr is the average difference in K be tween the outdoor temperature and -4  °C 
during the defrosting period. 
Qdefr applies only to bidirectional units wi th recuperative heat exchanger; for 
unidirectional units or units with regenerative heat exchangers, Qdefr=0. 
SPI and ηt are values derived from tests and calculation methods. 
Other parameters and their defau lts are given in Table 1. The SEC for label classification is 
based on the ‘average’ climate.  
EN 28   EN 2. The annual electricity consumption pe r 100 m² floor area (AEC) (in kWh/m².a 
electric per year); and the annual hea ting saved ((AHS), which means the annual 
saving in consumption of energy for heati ng (in kWh fuel gross calorific value per 
year) are calculated as follows, using the defi nitions in point 1, a nd the default values 
given in Table 1, for each type of climate (average, warm and cold): 
AEC = ta· pef· q net·MISC·CTRLx·SPI+Q defr;  
AHS = th·ΔTh·ηh-1·cair· (q ref – q min·CTRL·MISC·(1- ηt)).

ANNEX IX  
Verification procedure for ma rket 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. 
Member State authorities shall use the measurement and calculation methods in Annex VIII. 
Table 1  
Measured parameter  Verification tolerances  
SEC The measured value shall be no more than 
1.07 times the maximum required value 
Sound power level The measured va lue shall be no more than the 
maximum required value plus 2 dB
