RESNET Appoints Utility Billing Modeling Software Calibration Test

Software users often ‘true-up” or “calibrate” simulation models for existing homes to historical utility billing data with the goal of increasing the accuracy of retrofit savings predictions. This is typically achieved by adjusting input parameters within their ranges of uncertainty until a desired level or agreement is seen between pre-retrofit energy use and historical energy use. RESNET is entering into a process to develop a standard that would provide guidance and a method of test to evaluate calibration methods. This effort will be based upon some of the “self-test” concepts developed within the National Renewable Energy Laboratory’s Building Energy Simulation Test for Existing Buildings (BESTEST-EX ). The goal of this effort is to improve the accuracy and consistency of residential retrofit analysis by giving software developers a means to test how well various cali...
