i have troubles in evaluating building energy efficiency indicators, as i know , there're following kinds of ways or indicators :
1.building envelope
OTTV(Overall Thermal Transfer Value),
PAL(Perimeter Annual Load),
U-Value
2.facility or equipment
CEC/AC(Co-efficient of energy consumption for air conditioning )
EER(or SEER)
COP
my question is what're advantages and disadvantages or limitations of each indicator? Especially "PAL" indicator, it seems difficult to find some useful information about this index in english or chinese, is it only used in Japan?
thank your help very much!
All best wishes!
