EU Project News

5th iSERV Newsletter released

The 5th issue of the iSERV Newsletter was just released introducing the next stage of the project, where attention turns from data gathering and setting up the systems to be monitored towards physically inspecting and monitoring the indoor air quality (IAQ) of selected systems in conjunction with their energy consumption. At this stage of the project there are now 156 buildings in the database, 798 HVAC systems and 2975 HVAC components. These cover an area of 585,358 m². The aim of the concurrent testing is to gain confidence in where the benchmark performance standards are being set relative to IAQ, and to test whether the physical inspections are identifying the same problems and opportunities as are being identified from the metered data.
The Newsletter reports also about the iSERV workshop at REHVA’s World Congress CLIMA 2013 held in Prague on June 16 – 19, 2013. iSERV was presented in a well attended 1,5 hour workshop on The Practical Benchmarking of HVAC Systems Energy Efficiency in Use chaired by project coordinator  Professor Ian Knight from the Welsh School of Architecture (UK), and Zoltan Magyar REHVA vice-president. 
SAVE THE DATE: REHVA will organise a joint technical seminar with the iSERV project consortium in Brussels on 13 February 2014.

Ecodesign News   

Boilers and local space heaters – soon to be all covered by regulations?

After a very long process of preparation, the Ecodesign regulation for gaseous and liquid fuel boilers has been finally approved. For solid fuel boilers, the preparations in ENER Lot 15 started in 2008, and after some delays the work has proceeded towards the final steps. In parallel, also local space heaters (using either liquid, gaseous or solid fuels) have been subject to ecodesign studies in ENER Lot 20, and now it should finally be possible to look at all types of boilers and heaters “in one picture”.

The Regulatory Committee meetings for both Lot 15 and Lot 20 have now been scheduled for 23-24 September, it is important to note some essential changes, including the scope and the list of excluded products. It is also crucial for manufacturers to observe that requirements in both product groups would enter into force in one stage - instead of step by step tightening requirements, now all main requirements would enter into force four years after publishing of the regulation. As a new requirement, stringent limit values for nitrogen oxide emissions has been proposed.

Because of the many changes, it would be important for both Member States and individual manufacturers, as well as manufacturers’ organizations to study the current proposals carefully. The list of National contact points in charge of the implementation of the Ecodesign Directive 2009/125/EC can be found at

Solid fuel boilers (Lot 15):

After the Consultation Forum, there are a few significant changes in the proposed regulation. First of all, the upper limit of rated heat output has been extended from 500 kW to 1000 kW, bringing some new manufacturers within the scope. Also there are less product types excluded from the scope now. For example, Cogeneration space heaters were previously excluded from the scope, and now it is proposed to exclude “solid fuel cogeneration boilers with a maximum electrical capacity of 50 kW or above” .

 There are also changes in the definitions, for example an addition to the “solid fuel boiler” definition:
“has a heat loss to the space it is located in of no more than 6% of rated heat output”;

Local space heaters (Lot 20):

The draft ecodesign regulation establishes ecodesign requirements for the placing on the market and/or putting into service of domestic local space heaters with a nominal heat output equal or below 50 kW and commercial local space heaters with a nominal heat output equal or below 70 kW. It is worth noticing that the draft energy labelling regulation covers only heaters up to 50 kW, and it does not use definitions domestic and commercial.

Ventilation products – progress after a long silence?

Also for ventilation units of different sizes – small ones as one part of ENER Lot 10 and large ones within ENTR Lot 6, Consultation Forum was held in November 2012. The list of planned Regulatory Committee meetings indicates that also for ventilation units a meeting is planned for December 2013. This would mean that a proposal for ecodesign and/or labelling regulation could be sent to Member States in early autumn.
