Example Procedures for Developing Acceptance-Range Criteria for BESTEST-EX

Building Energy Simulation Test for Existing Homes (BESTEST-EX): Instructions for Implementing the Test Procedure, Calibration Test Reference Results, and Example Acceptance-Range Criteria

“…The concepts applied for establishing example acceptance ranges are described in Sections 1, 3, and 4 of Judkoff et al (2010b). As described in Judkoff et al (2010b), Section 2, programs must pass 100% of the physics test cases, and programs must pass a reasonable fraction (example: 80%) of the calibration test cases.…”

“…• B-EX-Phase-1-Ref-C-Results+Example-Acceptance-Criteria.xls: Spreadsheet that contains reference simulation results for the utility bill calibration tests; the building physics test case results are also included here for convenience. The example acceptance criteria presented in Judkoff et al (2010b) are applied to the physics and calibration tests results. Use BESTEST-EX-Phase-1-Output.xls (Judkoff et al 2010a) to enter simulation results for the program being tested.…”

“…Reference simulation input files are described further within README-BESTEST-EX-Calibration-Test-Files.doc, included with the accompanying electronic files. Reference simulation input files for the building physics tests are included with Judkoff et al (2010b). Tables Table 1. BESTEST-EX Example Range-Setting Procedure: Calibration Tests, Scenario C1H Table 2.…”

“…• Clarifications to Judkoff et al (2010aJudkoff et al ( , 2010b related to publication of calibration test results for non-blind testing, and other clarifications; see Appendix B of this document. There are no substantive changes to the test specification.…”

“…BESTEST-EX was initially published (Judkoff et al, 2010a(Judkoff et al, , 2010b with the intention that the calibration test results needed to be blind, so a certifying agency could use it for certifying calibration methods. After publication, it became apparent that the residential energy retrofit modeling industry wanted to have the ability to self-test their software, and we realized that this ability-consistent with self-testing capability provided for the BESTEST-EX building physics tests -would be beneficial to both software developers and users.…”
