Description

In 1994, ASHRAE began developing a guideline for measuring retrofit savings (GPC-14P). In support of Guideline-14P, ASHRAE initiated RP-1050 to develop a toolkit for calculating linear, change-point linear, and multiple-linear inverse building energy models. The resulting Inverse Modeling Toolkit (IMT) can be used as part of a procedure to measure savings. This paper describes the numerical algorithms used to find general least squares regression, variable-base degree-day, change-point, and combination change-point multivariable regression models in the IMT, as well as the equations used to estimate the uncertainty of predicting energy use for the purpose of measuring savings using IMT models.
