Dishwashers requirements for Europe

Perhaps not an exact answer to your question, but maybe a solution?

Since there are only requirements for residential dishwashers in NC and not commercial, you can use a A+++ rated machines instead in Europe, and just ignore Energy star. (A+++ does not yet exist on commercial dishwashers, EU are still debating this I heard). And A+++ machines should be easy to find in Poland as well right? The A+++ requirement is clear in v4.1 and you can substitute just this one credit for v4.1 if you want. I can’t double check with LEED Credit Library since the system has been down all week, but I hope I remember it correctly.  :)

Hi,

I can see that in the updated LEEDv4.1 guide they removed the requirement to use A+++ rated machines. Now the credit language says that dishwashers have to have a "EU A label". Does it mean that they lowered this requirement and now it's enough to install equipment with just A rating without any "+"?

Agata,

Yes, you are correct, if you can still find products in the old EU labelling system.

I myself thought that the A came into place after the A+++ system was swapped to the new A-G system, and that A+++ in the old system was A in the new system. But a colleague of mine pointed out that the A came into place before that, he also had a conversation with LEED coaches on the topic. However, since A+++ is no longer available here (only A-G) that is a problem. In the new system very few products exist that are A, and USGBC will not take a product in the new system that for example is C, and better than A in the old system. They would only take a C-rated product if “…demonstrate performance equivalency both in energy and water consumption”, which is hard to compare. We have pointed out to them that it is urgent to give as a new requirement/threshold according to the new European label.  

Hi Maria,

In relation to everything you mentioned above, has there been any subsequent feedback from the USGBC?

It continues to be unclear and difficult to find products that, under the new EU label system, are A. We have found some C-rated products that seem to meet the ENERGY STAR criteria, but the units for energy consumption between the two systems are different and therefore difficult to verify.

Hi Bruno,

No, I haven’t heard anything new on this topic. And the text in the manual is still the same. The only thing that has changed a bit here in Sweden would be the market, there are now some dishwashers and washing machines that are A rated. Brands that I can find here with an A rating are: Miele, Bosch/Siemens, Samsung, Electrolux for dishwashers and for washing machines AEG, Beko, Bosch, Cylinda, Electrolux, Hisense, LG, Miele, Samsung, Siemens, Whirlpool for example.  

Hi Bruno - Did you get anywhere with C rated dishwashers that appear to meet Water Sense critiera? It is typically easy to find water use per cycle, and energy use per 100 cycles. Can we compare this with the Energy Star criteria, or do we need to go deep into the exact Energy Star Methodology?

Thanks.

Hi Rachel - Actually, we haven't been able to come up with any final results yet, as the projects are still under review and we don't have final feedback on them. The big problem really is: "How do the Energy Star energy criteria compare with the Eco-Label criteria?".

I did some research, and according to the technical specifications for each type of equipment, and the old label, we can see that there are different numbers as a basis for calculationg the number of annual cycles. In other words, for Diswashers (Delegate Regulation (EU) n.º 1059/2010) we have 280 cycles per year as the baseline; for Washing machines (Delegate Regulation (EU) n.º 1061/2010) we have 220 cycles per year as the baseline; for cloths dryers (Delegate Regulation (EU) n.º 392/2012) we have 160 cycles per year as the baseline.

With this information, it seems possible to determine the annual consumption, since the new label gives the amount of energy expressed in kWh/100 cycles. 

Whether or not this methodology will be accepted is more difficult to now, as there is still no feedback on our projects. Perhaps now with this post someone will be able to shed more light on these issues.
