building energy efficiency

(OP)
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!
