The Building Energy Simulation Test for Existing Homes (BESTEST-EX) Methodology

Ron Judkoff, Joel Neymark, Ben Polly

Abstract: The authors developed a method for testing the reliability of models that predict retrofit energy savings, including their associated calibration methods. The test suite applies the new Building Energy Simulation Test for Existing Homes (BESTEST-EX) Methodology, developed by the National Renewable Energy Laboratory in consultation with home energy retrofit industry software developers. BESTEST-EX includes building physics test cases with fully known inputs, and calibrated energy savings test cases with specified base-case monthly utility billing data and uncertainty ranges for selected inputs. The test cases apply a variety of retrofit scenarios in a heating and a cooling climate.
