This paper presents a new methodology for screening measured data from buildings where heating, cooling, and electricity consumption are separately recorded. It defines energy balance load (EBL) as the difference between the heating requirements plus the electric gains in the building and the cooling coil loads. It then applies first law energy balance in conjunction with the concepts of analytical redundancy, trend checking, sensitivity, and uncertainty analysis to develop a methodology using measured values of E BL to identify bad data. This paper is the first part of a two-part series; it presents the theoretical basis for the methodology and illustrates its use on samples of measured building data. In part two, a program that was created to automatically pre-screen the measured building energy consumption data by utilizing EBL methodology and case studies will be introduced. © 2006 ASHRAE.
