ABSTRACT
Measurement and verification have become more complicated in recent years to address the concerns of utility energy efficiency practitioners. Their concerns, outlook and background are different than those of performance contractors. Many of the concepts that are applicable to the utility energy efficiency practitioners are not useful to performance contractors. One example is uncertainty calculations which are not necessary for a performance contract. This paper critiques the latent and overlooked inconsistencies associated with uncertainty calculations.
