Less than zero


IT’S easy to understand, “10% less energy” but “179% less energy”?

Another item on the Energy Commission website also carries what seems to be contradictory information:

“3 Stars ... -10% = STAR Index <+10%”

Does this mean that an “average 3-Star model” (in the Description of Parameters) consumes less energy than the reference average level? sm

Sorry, I didn’t study much mathematics and I can’t answer your second question.

Regarding your first question, in my simple layman’s view, 100% less of anything would be nothing. So, it seems impossible to me to have 179% less of anything. Can we have a minus amount of energy?

Would anyone who is more well-versed in statistics or mathematics care to answer the above questions? Fadzilah Amin
