Ecodesign News

Ventilation products

For Ventilation units, the first Working Document containing a draft regulation of ecodesign and labelling, was discussed in November 2012 at the Consultation Forum. The document was based on the “Ventilation” parts of ENER Lot 10 and ENTR Lot 6. The borderline between “residential ventilation units” and “non-residential ventilation units” was defined as follows: units with fans of less than 125 W power input are regarded as “residential”, and larger ones as “non-residential”. The proposed regulation, however, gives the manufacturer the possibility to decide the category of the unit independently of the size. 

Labelling requirements are prepared for “residential ventilation” only, because energy labelling is primarily for consumer products.  

In September 2013, a new Working Document was sent to the Member States for comments, in order to prepare the final voting at the Regulatory Committee, scheduled to be held on 16-17 December 2013. 

Now the borderline between “residential” and “non-residential” units is expressed in a different way, instead of fan power this is now related to the nominal air flow, as follows:

“Residential ventilation unit’ (RVU) means a ventilation unit fulfilling one of the following conditions:
(a) the maximum flow rate does not exceed 250 m³/h;
(b) the maximum flow rate is between 250 and 1 000 m³/h, and the manufacturer declares its intended use as being exclusively for a residential ventilation application”

For residential ventilation units, the main requirement is expressed as a “Specific Energy Consumption for ventilation per m2 heated floor area of a dwelling or building” (SEC). The main parameters affecting the SEC value are the recovered heat from extract air and the fan energy consumption, but also many other parameters like the type of control of the unit, the motor and drive type, and possible defrosting are also taken into account. This SEC value was actually introduced already in 2012 but only in the Consultation Forum draft for Labelling, not for Ecodesign. The SEC value actually depends on the climate, which also makes both the definition and the calculation look complicated. 

The most significant change for non-residential ventilation units was to replace the fan efficiency and face velocity requirement by the Specific Fan Power (SFP). However, the SFP is defined in a new way, different from the definition in EN 13779, here as “internal specific power of ventilation components”. The maximum value of SFP is expressed using an equation, which gives an “efficiency bonus” if the heat recovery system has an efficiency higher than the required minimum, and also a “filter correction” which is kind of penalty in case the ventilation unit is equipped by lower class filters than a “reference configuration”, in which the supply side filter is a clean fine filter F7 and exhaust side filter is a clean medium filter M5. In addition, the maximum SFP depends on the nominal air flow of the unit.

If the proposed regulations are approved at the Regulatory Committee, then the requirements will enter into force in two steps: first in 1 January 2016, and more stringent requirements in 1 January 2018. For example, the minimum efficiency of a non-residential ventilation unit with a run-around heat recovery will be 63% from 1 January 2016, and 68% from 1 January 2018, for other types of heat recovery system the minimum is 67% (2016-) and 73% in 2018.

European Policy News

2030 framework for climate and energy policies

The European Commission is expected to unveil proposed 2030 green energy goals around the year end.  The development of a 2030 framework for the EU climate change and energy policy is necessary to make progress towards a competitive economy and to support a secure, sustainable and payable energy system. EU Energy Commissioner Oettinger has announced to present a legislative proposal for a 2030 framework by the end of the year. The aim is to set intermediary targets between the EU 2020 aims and the 250 roadmap based on several analysis about what was achieved so far from the 2020 targets.
As preparatory step for the 2030 framework for climate and energy policies, a Green Paper was adopted on 27 March 2013 (COM (2013)169). It presents progress made and challenges under the current policy framework and sets out for consultation four key issues the framework needs to address: targets; coherence of instruments, fostering competitiveness of the EU economy and security of supply; and acknowledging the differing capacity of Member States.

Horizon 2020 energy: draft work programme 2014-2015 now available! 

The draft work programme 2014-2015 of Horizon 2020 in the area of "Secure, clean and efficient energy" has been published. The programme includes funding opportunities for research topics (former FP7 programme) as well as for previous “IEE-type” activities promoting market deployment. The draft programme is under approval by the EC. The final call for proposers is supposed to be launched in December 2013, most probably during the HORIZON 2020 Energy Infoday organised in Brussels on the 5th of December.

2014-2020 EU Budget approval provides boost to Energy Efficiency in Buildings

The legislative package for the Multi-Annual Financial Framework, which includes the Structural Funds for 2014-2020, was officially approved in the European Parliament. The Structural Funds can and must now be used for more projects on sustainable energy and energy efficiency, including on buildings, according to EuroACE. - Source: eceee

Study: insulation could save European industry €3.5 billion a year

Better insulation could shave 4% off European industry’s total fuel consumption and emissions bill, a sum worth €3.5 billion a year, says an unpublished report by the Ecofys consultancy. The total cost-effective energy savings potential amounts to 620 petajoules (PJ), the equivalent of 37 million tonnes of CO2 emissions, according to the paper, ‘Climate protection with rapid payback’, which is due to be published next week.
The study estimates the initial investment costs of insulating bare industrial surfaces and repairing damaged industrial insulation at about €900 million. But the payback times for the majority of such investments were under one year and sometimes just a few months.
Around 10% or more of the industrial insulation in Europe’s industrial plants is estimated to be uninsulated or covered with damaged insulation. Remedying this would slash industrial energy consumption by 3%. - Source: EurActive

REHVA position paper on indoor air quality

REHVA IAQ experts prepared a position paper on indoor air quality and climate addressing policy makers and authorities. The paper points out potential conflicts between energy efficiency, occupancy and indoor air quality and climate. It uses the result of the HeathVent project and other EU projects, and is linked to the work of a new REHVA Task Force aiming at preparing further position papers in the future on Indoor Environment. The Task Force wants to achieve a better understanding within decision makers on IAQ issues and to have an impact on EU and national policy and regulations. The first position paper is available in the REHVA website.


New BPIE report on Boosting building renovation, an overview of good practices

End of September 2013, the new French government reaffirmed its previous ambitions to massively increase building renovation rates, with the overall goal to refurbish 500,000 buildings per year by 2017. To support the French debate around renovation roadmaps, the French NGO CLER commissioned BPIE to produce a report on successful building renovation programmes, as an overview of good practices in Europe and around the globe. This report was presented in Paris to a large group of stakeholders, from building industry and real-estate associations, environmental organisations, consulting firms and Ministries (Housing and Environment / Energy). The report is available in the BPIE website
