Good morning,
We are working on a LEED project in Australia, and Commercial Washing Machines are part of the project. It seems the CEE rating that is outlined in the v4 requirements is not longer existant, and we were looking to achieve the v4.1 Energy Star eqivalent performance.
Does anyone have experience with both American Energy Star certification, and an Australian Energy Star/WELS rating, and understand how they compare in performance? We have reached out to Energy Star in the USA to understand how the MEF and WF are calulated, but if someone is already aware of what Australian Energy Star rating is equivalent to Energy Star certification in the US, that would be excellent!

Following. Was there an offline response to this?
Thanks!

The off-line response from the GBCI was as a couple of other threads noted. At the time of LEEDv4 pulication, the CEE Tier 3A thresholds for commercial washing machines were an MEF of 1.8, and WF of 7.5; and as such it needs to be demostrated that the commercial washers achieve these. It should be noted that the current Energy Star performance referenced in V4.1 is more onerous; MEF 2.2, WF 4.0, so it is not advantageous to target the v4.1 version of the prerequisite.
The MEF calculations are relatively straight forward, but based on energy and water consumption per cycle, which will need to be provided by the manufacturer. Details are found here, https://www.energystar.gov/sites/default/files/asset/document/ENERGY%20S...
I am still not quite certain how they compare to the Australian Energy Star and WELS ratings. But the MEF and WF should be able to be calcuated by the manufacturer. I would recommend sending the pdf in the above link to the washer manufacturer, and get them to confirm what the MEF and WF would be for the proposed washing machine.

Has anyone come across a top-load washer that meets the requirements for CEE Tier3a? Or successfully made an argument that your project was exempt from meeting the CEE Tier 3a requirements ?
