The tests in this section are intended to verify that the software correctly constructs the Standard Design model and applies rules of the 2013 Nonresidential ACM appropriately to the proposed and Standard Design models. The rule set implementation tests cover representative portions of the rules for building envelope, lighting, daylighting, space use data and HVAC. For each test there is a set of three models defined:
•User Model – the user model contains the user inputs for the as-designed building. In most cases, the values for the Proposed Design will be taken from user inputs with no modification. However, there are some cases where the building input is prescribed for the Proposed Design, or constrained by mandatory minimums or other rules.
•Proposed Design Model – the proposed model is defined by the rules in the ACM Reference Manual and created by the vendor software and is the building modeled for compliance. This model takes user inputs for building geometry, building envelope, lighting and HVAC and is used in the compliance simulation.
•Standard Design Model – this is the baseline model defined by the ACM Reference 'Manual modeling rules, and is the basis for comparison that determines whether a building passes compliance using the performance method.
These tests do not require that simulation outputs be verified, but they do require that simulation input files for the Proposed Design and Standard Design are properly constructed according to the rules in the ACM Reference 'Manual. Some tests require that sizing runs be performed, for HVAC inputs whose values are dependent on autosized Standard Design systems.
The test runs described in this section represent the Title-24 2013 Non-Residential ACM code compliance calculation and use the following Prototype Models- Small Office Building, Medium Office Building, Large Office Building, Warehouse Building and Small Hotel. For further details on the Prototype Models, refer to Appendix 3C. Each of the Standard Design test cases shall be created by modifying the Prototype Model as described in Section IV of this document. The modified Prototype Model shall form the proposed case for each test run. The Standard Design model shall be generated by compliance software as per the rules in the 2013 Nonresidential ACM. The Standard Design and proposed model files for each of test cases shall then be evaluated to verify that:
•The Standard Design building envelope constructions are correctly substituted for exterior opaque surfaces and fenestrations.
•Fenestration area in the Standard Design building is reduced in accordance with the 2013 Nonresidential ACM 'Manual, when the Proposed Design fenestration area is greater than 40% of the exterior wall.
•Skylight area in the Standard Design building is adjusted in accordance with the 2013 Nonresidential ACM 'Manual, when applicable.
•Default schedules of operation are applied for both the Standard Design building and the Proposed Design.
•The Proposed and Standard Design cases use the same defaults or tailored inputs for internal loads as required by the 2013 Nonresidential ACM 'Manual.
•The Standard Design building lighting system is correctly specified and that exterior lighting is modeled.
•Receptacle loads, process loads is modeled according to the rules in the 2013 Nonresidential ACM 'Manual.
•The Standard Design building use the correct system types as prescribed in the 2013 Nonresidential ACM Manual.
•An economizer (of the right type) is included in the Standard Design building if required.
•The primary and secondary Standard Design building systems are properly specified and sized.
•Fan brake horsepower is correctly specified for the Standard Design building.
•Prescribed modeling assumptions are applied for both the Standard Design building and the Proposed Design.
•Overhangs are modeled in the Proposed Design for Test Case 7 but not the Standard Design building.
•Unconditioned spaces are modeled.
•Other Standard Design building specifications and/or modeling assumptions are correctly applied.
As the software developer verifies the various test conditions, the input and output files should be annotated with comments or other methods to demonstrate that the modeling rules specified in the 2013 Nonresidential ACM Manual are correctly applied. Software developers should use the spreadsheets included in Appendix 3C, to report the results of these tests. These annotated files shall then be submitted to the Commission for further evaluation. Any errors discovered shall be corrected by making modifications to the software; the runs shall be repeated; and the new results shall be annotated for submittal to the Commission.
The Standard Design Tests are labeled using the format:

The applicant shall perform all tests specified in Section IV and report the outputs in the forms provided in Appendix 3C. Note that the Standard Design for some inputs, such as cooling efficiency and pump power, are dependent upon the autosizing of the HVAC equipment. The ruleset implementation tests do not check that the autosized capacity matches the Reference Method, but rather, that the Standard Design input is properly defined in relation to the autosized capacity.
