    CBECC-COM 2016 is an open-source software program developed by the California Energy Commission for use in complying with the 2016 update to the Non-Residential Building Energy Efficiency Standards.


    New in this version:
    • Addition of 2016 TDV factors
    • Added 2016 opaque envelope u-value requirements
    • Added 2016 lighting power densities to the space function data table
    • Added 2016 changes to HVAC equipment design efficiency
    • Changed baseline for non-recirculating residential water heating systems to instantaneous gas water heaters
    • Correction of metal building roof u-values based on changes to Joint Appendix 4

    IMPORTANT: This version of CBECC-Com enables the ability to perform analysis using a choice of rulesets. When an existing model is loaded, the active ruleset will be set to the ruleset in which the model was created. To analyze that model using a different ruleset, go to the 'Ruleset' menu item and select the desired option. For example, if you have a model that was created using the Title 24-2013 ruleset (using v3c for example), you can perform analysis of that model under the 2016 version of Title 24 by selecting Ruleset/CA 2016 Nonresidential, Vers. 2.0 (CEC 2016 NonRes.bin), as shown below.




    Note:
    • CBECC-Com 2016-4-alpha has not been approved by the California Energy Commission for Title 24 compliance. This version comes bundled with EnergyPlus 8.1. Users do not need to install EnergyPlus 8.1 separately.
