Shaping the Future
Eco-design Directive, LOT10 und LOT11 Eco-design Directive, LOT10 und LOT11

Our use of energy is changing. From the perspective of European legislation too. The ErP Directive ensures that 'Energy-related Products' have to be clearly labelled.

This page explains the key content of the ErP Directive in relation to air conditioning technology and heat pumps.

We can help you find the right solution, regardless of whether you wish to efficiently heat or cool – to meet your needs and also conserve the environment. Shape the future with us!

The European Union is Setting High Targets

The European Union is pursuing ambitious climate protection targets, with important milestones to be reached by 2020 compared to 1990:

20%
Lower useof primary energy
20%
Morerenewable energy
20%
Fewer CO2-emissions

The ErP or evenEco-design Directive

It is against this background that the EU introduced the ErP Directive, which is intended to support and advance the resource-conserving, energy-efficient design of energy-related products. The ErP Directive applies to products that meet the following criteria:

  • Minimal annual sales in the EU of 200,000 products
  • Major impact on the environment
  • Significant potential for improving environmental tolerability at reasonable cost

Products are divided into product groups known as lots. With regard to heat pumps, Lot 1 is relevant for space and combination heaters and Lot 2 for water heaters. Lot 10 is relevant for air conditioning units - to date up to a cooling output of 12 kW.

The Provisions of the ErP Directive

The ErP Directive is based on two implementing regulations: the Eco-design Directive for CE labelling and the Energy Labelling Directive.

CE-Labelling

CE Labelling

The Eco-design Directive defines so-called minimum efficiency and minimum emission standards. Products that do not meet these standards are not awarded CE marking and may no longer be imported into the EU. This required manufacturers, above all, to work with technologies that are CE-compliant, now and in the future.

EnergyLabelling

Energy Labelling

The Energy Labelling Directive sets out how the Energy Labels should look. It defines which values are needed for classification in a specific efficiency class. The labels are intended, above all, to help consumers to compare products and select them based on their efficiency.

Seasonal measurement criteria for cooling and heating modes

Formerly:
Performance measurement at only one measuring point in cooling and heating mode

Prior to 2013, air conditioning units were only rated by their EER and COP and heat pumps only by their COP. EER rated efficiency in cooling mode. COP defined efficiency in heating mode. The values were orientated towards a single operating point – less realistically and disadvantageously for consumers.

The performance data is only recorded at a single measuring point during full-load operation for the COP and EER.

Leistungsmessung mit nur einem Messpunkt
Leistungsmessung mit nur einem Messpunkt

With the ErP Directive:
Optimised performance measurement at four measuring points in cooling and heating mode

The performance data for SEER and/or SCOP is recorded at four different measuring points in line with DIN EN14825. The measuring points are weighted differently according to the temperature curves of the reference climate in Strasbourg, in order to reflect the energy efficiency of the unit under the most realistic conditions possible.

The following are also taken into consideration:

  • Thermostat-Off consumption
  • Standby consumption
  • Crankcase heating
Leistungsmessung bei vier Messpunkten
Leistungsmessung bei vier Messpunkten
The SCOP value recorded is included in the calculation of the seasonal space heating energy efficiency (ηs) within Lot 1. Space heaters have to meet certain minimum requirements depending on the energy carrier used. The yardstick for heat pumps is significantly higher than for all other technologies. The energy efficiency of hot water heating (ηwh) is relevant for the energy efficiency classification in Lot 2.

The ErP Directive for Heat Pumps

The deadline for the energy efficiency of space and combination heaters to be labelled EU-wide is 26 September 2015. The benefits of heat pumps are immediately visible, unlike fossil-fuelled or pellet-fired heating systems. Heat pumps consistently achieve green ratings (A+ or better).

The Energy Labelling Directive relates to units with a nominal output of up to 70 kW. What is crucial here is that a single annual energy consumption figure does not work on labels, unlike say on a washer-dryer or refrigerator. The consumption of a heating unit always depends on the building in which it is installed, explaining why the classification is based on "seasonal space heating energy efficiency".

We have made available all the technical data sheets on our air conditioning and heat pump systems.

The ErP Directive for Room Air Conditioning Units

The Implementing Regulation (EU) 206/2012 entered into force on 1 January 2013. It implements the requirements of the ErP Directive 2009/125 EC for air conditioning units with a cooling capacity of up to 12 kW. In terms of energy labelling, the efficiency class scale up to A was extended to A+, A++ and A+++.

It is evident why air conditioning units also fall within the ErP Directive: Air conditioning technology is now firmly rooted in everyday life – in cars, offices and within our own four walls. Technical developments in recent years have already brought about significant progress in this field. At Mitsubishi Electric, it is essential that we also make a significant contribution to energy efficiency.

The Directive also defines the maximum sound power level for heat pumps depending on the heat capacity of the heat pump. The energy label carries the figures. The label shows the sound power level of the indoor and outdoor unit in decibels as an objective acoustic variable.

Sound Power Level

Sound Pressure Level dB(A)

The sound pressure level is a sound field variable and gives the operating noise of an indoor or outdoor unit perceived at a specified distance.

Sound Pressure Level

Sound Power Level dB(A)

The sound power level is an acoustic variable that defines the source strength of the sound generator and thus is independent of the distance to the receiver.

The technical data sheets for the units give the sound power level as well as the sound pressure level. It describes in acoustics the metrologically recorded level generated by a sound source at a specific distance.

Consumers are also given relevant information on the energy label about the noise emissions of their air conditioning system. The label shows the sound power level of the indoor and outdoor unit in decibels as an objective acoustic variable.

Sound Power Level

Sound Pressure Level dB(A)

The sound pressure level is a sound field variable and gives the operating noise of an indoor unit perceived at a specified distance.

Sound Pressure Level

Sound Power Level dB(A)

The sound power level is an acoustic variable that defines the source strength of the sound generator and thus is independent of the distance to the receiver.

The technical data sheets for the units give the sound power level as well as the sound pressure level. One advantage of this is that it is possible to compare different air conditioning units independently of the installation and process for measuring the sound level. The sound level is often measured at a distance of approx 1 metre, with modern split air conditioning units averaging a very quiet 21 decibels.

Climate Zones for Heating Mode

Climatic conditions play a key role in evaluating heat pumps. They are split into three climate zones on the energy label: cold, moderate and warm. The measuring points are at -7 °C, 2 °C, 7 °C and 12 °C. Unlike with air conditioning units, the climate zones on the energy label for heat pumps are coded in shades of blue.

Climate Zones for Heating Mode

As the climatic conditions have a major impact on the operating performance in heat pump mode, three climatic zones have been formed within the EU: warm, moderate and cold. The measuring points are uniformly at 12 °C, 7 °C, 2 °C and -7 °C. The colour of the climate zones for air conditioning units differs from that for heat pumps.

Questions & Answers

  • Is there a better classification today than A++?Today individual units can achieve a maximum energy efficiency class of A++ on the product label. It is impossible to achieve a higher rating and this cannot therefore be shown. It is altogether different with composite units. In the very best case, a complete system can be labelled with energy efficiency class A+++. This is certified on the composite label.
  • Will the provisions of the directive still change?A number of changes are already a foregone conclusion. In four years time, "Label II" will replace the current energy efficiency label. Then individual units will be able to achieve energy efficiency class A+++. D will be at the bottom end of the scale (instead of G today).
  • Why does the appearance of the energy efficiency label differ for different heat producers?Different heat generators are rated in Lot 1 within the Eco-design Directive. However, other points have to be taken into consideration with fossil heat generators than with heat pumps. This is reflected in the appearance of the energy efficiency label. As the efficiency rating for all heat generators is based on the seasonal space heating energy efficiency, the efficiency classes are now comparable with each other.
  • Does the new ErP Directive apply in all EU states or is it graded?The same rules of the Implementing Regulation for the ErP Directive for heat generators (Lot 1) apply in all EU states.
  • Does the ErP also relate to goods in stock?All heat generators imported by 25 September 2015, held in stock by the manufacturer or dealer, are unaffected by this and may be sold.

Questions & Answers

  • Today an A and tomorrow an A+++?The new measuring method will classify energy efficiency into new classes. An air conditioning unit classified today as an "A" can slip into a significantly worse class in line with the new ErP Directive. The minimum requirements do not affect the classification of the products.
  • What benefits does the new ErP Directive offer professionals and users?The three new efficiency classes mean that air conditioners can now be more clearly differentiated from each other in terms of their efficiency. There is much greater clarity about electrical consumption and noise emissions – for the first time standardised for all manufacturers' air conditioners, leading to greater transparency for consumers.
  • Does the new ErP Directive apply in all EU states or is it graded?The Implementing Regulations for the ErP Directive for room air conditioning (Lot 10) came into effect on 1 January 2013 and the same rules apply in all states of the EU without national transitional periods.
  • Does the ErP also relate to goods in stock?All air conditioning units imported by the end of 2012, held in stock by the manufacturer or dealer, are unaffected by this and may be sold.
  • What happens in the event of the partial replacement of air conditioning units into existing systems?Existing air conditioning systems enjoy comprehensive protection. If individual units are replaced owing to technical defects, then only the newly installed products have to meet the requirements of the ErP Directive. Air conditioning units that are not replaced, are therefore not subject to the regulations set out by the ErP Directive.
  • Who benefits from the new ErP Directive and who loses?The winners among air conditioning units in future will specifically be products with innovative inverter technology. The ErP Directive will now ensure that suppliers of inefficient units are prevented from entering the market.
  • Will there be an efficiency boost in new air conditioning units brought about by the new ErP Directive?Many of our air conditioning units have far exceeded the existing standards due to our technological edge in inverter technology. The difference in energy consumption between a product currently rated as the best air conditioning unit and the future A+++ classification can be huge: the energy consumption can be up to 70 % lower and the user's energy costs will therefore also drop.
