Inverse Modelling Toolkit (IMT): numerical algorithms.

Author(s) : KISSOCK J. K., HABERL J. S., CLARIDGE D. E.

Summary

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 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.
