  1. Download/Install CBECC-Com

    CBECC-Com v3b: Click here to download and install CBECC-Com 2013 v3b (Build 717) - Certified by California Energy Commission

    New in this version:
    • Window specific overhangs and fins that can be defined in the CBECC interface for both Simplified and Detailed Geometry
    • Added the ability to use the domestic hot water heater to also provide space heating, e.g., residential 'Combo' heating/DHW heating systems.
    • Added partial compliance option for ‘New Envelope and Mechanical’ compliance.
    • Baseline window (vertical fenestration) performance is now selected based on proposed design window 'product type.'
    • Baseline skylight performance is now selected based on proposed design skylight curb type and skylight glazing type.
    • Updates to defaulting of lighting status for Additions/Alterations compliance. Default lighting status now tracks envelope status.
    • IDF file import option for proposed case to support Exceptional Calculation Methodology
    • Significantly expanded compliance report including new inputs for reporting data
    • Optional user input of space perimeter for Simplified Geometry models allows tailored method lighting inputs to be utilized
    • Add checks to help ensure zone systems have the appropriate heating and cooling coil types
    • Add checks to ensure zones that are classified as 'Unconditioned' are not served by ventilation systems with heating and/or cooling capacity
    • Add checks to ensure AirSegment:Type = 'Exhaust' is only used with AirSystem:Type = 'Exhaust'
    • Thermal zones in the proposed design which exceed unmet load hour limits will no longer terminate compliance analysis but will generate a warning, and will be included in a new table on the compliance report
    • Bug-fixes - see Quick Start Guide for details
