Description

Standard 140 specifies a standard method of test for evaluating the technical capabilities and applicability of software used in calculating the thermal performance of buildings and their HVAC systems. These test procedures can be used to identify and diagnose predictive differences from whole-building energy simulation software that may be caused by algorithmic differences, modeling limitations, faulty coding, inadequate documentation, or input errors. The current set of tests focuses on building thermal envelope and fabric loads and HVAC equipment performance and includes 1. comparative tests, in which a program’s results may be compared to a different version of itself or to the results of other programs, and 2. analytical verification tests, in which a program’s results may be compared to analytical, quasi-analytical, or verified numerical model solutions. This procedure tests software over a broad range of parametric interactions and for a number of different output types, thus minimizing the concealment of algorithmic differences by compensating errors. Different building energy simulation programs, representing different degrees of modeling complexity, can be tested. However, some of the tests may be incompatible with some building energy simulation programs. The revised 2017 edition of Standard 140 includes all the test cases of Standard 140-2014 and adds a set of analytical verification test cases for evaluating air-side HVAC equipment models.

207	8. CLASS II OUTPUT REQUIREMENTS 8.1 Reporting Results 8.1.1 Standard Output Reports. The standard output reports included on the accompanying electronic media shall be used. Instructions regarding these reports are included in Normative Annex A2. Information required for this report includes the following: 8.1.2 Simulation Input Files. All supporting data required for generating results with the tested software shall be saved, including the following: 8.1.3 Omitted Test Cases. If a program being tested omits a test case, the modeler shall provide an explanation using the modeler report template provided in Normative Annex A2. 8.1.4 Discussion of Anomalous Results. Explanation of anomalous test results using the modeler report template provided in Normative Annex A2 shall be permitted but is not required. 8.2 Output Requirements for Building Thermal Envelope and Fabric Load Tests of Section 7.2. All results shall be entered into the appropriate standard output report (see Normative Annex A2) as specified below. 8.2.1 Tier 1 Tests. For the Tier 1 tests, generate output for comparison to the example results as shown in Table 8-1. Seasonal results shall be for heating and cooling seasons for the entire year or some other reasonable length as defined by the too… 8.2.2 Tier 2 Tests. For the Tier 2 tests, generate output for comparison to the example results as shown in Table 8-2. Seasonal results shall be for heating and cooling seasons for the entire year or some other reasonable length as defined by the too…
