FAQs about WEp1 :

How does the CEE Tier 3A criteria for commercial clothes washers compare to ENERGY STAR certified washers?

Is the WaterSense label really required, even if a non-labeled fixture has a comparable flush or flow rate?

Not all fixture types can get the WaterSense label. Which fixtures do we need to ensure have the WaterSense label for our project?

Hi,

can i use below washing and dryer machine specs as energy star rated.

Washing machine:

Rated Capacity 9 kg

Energy efficiency class - A+++ (most efficient) to D (least efficient) :  A+++

Annual energy consumption (AEC)2 kWh/year:  109

Weighted annual water consumption (AWc)3 Litres/year:  11,000

 

Dryer:

Rated Capacity 9 kg

Energy efficiency class - A+++ (most efficient) to D (least efficient) :  A+++

Annual energy consumption (AEC)2 kWh/year:  174

 

While searching machines on the energy star website, we found that the units are available in cu feet but client has a requirements in terms of kg, is there any conversion rate for washing machine from cubic feet to the kg.

Energy Star ask the compliance in terms of IWF and MEF but the it does not mentioned any unit/demo to calculate these values like capacity in what(kw/kg/cc) and many of the suppllier dont mentione the wash cycle, etc.

Thanks marcus for your reply. I will check it again but with change in maf with the same capcity(in kg/volume) the power and water consumption varies. Energy Star ask the compliance in terms of IWF and MEF but the it does not mentioned any unit/demo to calculate these values like capacity in what(kw/kg/cc) and many of the suppllier dont mentione the wash cycle, etc. Is above mentioned dryer and washer is complying with Energy star requirements..??
