RESNET Model Calibration Test Method Working Group Adopts Title, Purpose and Scope of Activities

May 6, 2013

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, http://www.nrel.gov/docs/fy11osti/52414.pdf).

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 calibration methods work.

The working group has adopted a Title, Purpose and Scope of Activities to guide its work.

The title adopted by the working group is:

Standard Method of Test for the Evaluation of Building Energy Analysis Model Calibration Methods

The purpose adopted is:

This standard specifies a method of test for evaluating calibration methods that are used to reconcile building energy models with measured energy consumption data.

The scope of activities adopted is:

This standard test procedure applies to calibration methods used with computer programs that predict the energy performance of residential buildings.

The chairman of the working group is Ron Judkoff of the National Renewable Energy Laboratory.  Members of the working group are:
