Development of a Toolkit for Calculating Linear, Change–Point Linear and Multiple–Linear Inverse Building Energy Analysis Models, ASHRAE Research Project 1050-RP, Detailed Test Results
MetadataShow full item record
This is the detailed test report for the ASHRAE 1050-RP project. This report presents the detailed results of the testing of IMT (Inverse Modeling Toolkit). Two kinds of testing were performed, bounds testing and accuracy testing. The bounds testing is performed in order to identify what types of data sets the IMT program can model reliably. A variety of data sets were used to test the limits of the program: 1) Data sets with as few as two and as many as 9,000 data points, 2) Data sets with very large and very small numbers, 3) Data set with a variety of slopes, and 4) Data sets with tightly packed and widely scattered observations. In terms of accuracy test, 1P, 2P and MVR models were benchmarked against the statistical software SAS (SAS Institute Inc., 2001). The change-point model results (3P and 4P) were compared to those calculated by the data analysis software EModel (Kissock et al., 1996). Finally, the IMT's HDD and CDD models were compared to PRISM HO and CO models (Fels, M. et al., 1986).
