Full Description

ASHRAE Guideline 14p specifies guidelines for measuring energy savings from building energy-conservation retrofits. A primary method for measuring retrofit savings recommended by ASHRAE Guideline 14p involves identifying a regression model of baseline, or pre-retrofit, energy use as a function of influential variables, such as weather or occupancy, which may change between the pre- and post-retrofit periods. The regression model is then used to preduct how much energy the building would have consumed in the post-retrofit period, or as the difference between baseline and post-retrofit models applied to the same weather year.

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 (IMT), also included, 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 of testing.

This report can be used, copied, and distributed by GPC 14 for committee work only on Guideline 14.
