Abstract

This report summarizes the results of ASHRAE Research Project 1050: Development of a Toolkit for Calculating Linear, Change-Point Linear and Multiple Linear Inverse Building Energy Analysis Models. The Inverse Modeling Toolkit (WIT) is a FORTRAN 90 application for developing regression models of building energy use. IMT can identify single and multi-variable least-squares regression models. It can also identify variable-base degree-day and single and multi-variable change-point models, which have been shown to be especially useful for modeling building energy use. This report includes background information about IMT and the models, instructions for its installation and operation, and the results of accuracy and robustness testing.

Description

The report comes with an IMT CD-ROM. The IMT CD-ROM contains two folders: 'Detailed Test Results7 and 'IMT Software'. The results of extensive bounds and accuracy tests, including the data files and WIT output, are in the 'Detailed Test Results' folder. IMT source and executable files, along with sample data and instruction files, are in the 'IMT Software' folder.
