    New in this version:
    • For zones where there is no cooling, modified the baseline to also not have cooling.
    • Added efficiency modifiers for zone systems that will not be tested for duct leakage and meet the criteria in Section 140.4(l).
    Bugs fixed in this version:
    • Corrected DHW internal calculations for High-rise Residential and Hotel/Motel Guest Rooms
    • Fixes to opaque envelope UA-value checks
    • Updates to EnergyPlus service hot water heating rules to better align with the Appliance Efficiency Standards
    • Fix issue with baseline models not getting exhaust fan if proposed is 'Forced' mechanical ventilation
    • Add warning to user when proposed res zone has 'Forced' ventilation from Pri/Sec system, but also has exhaust fan defined. In this case, it is assumed the exhaust is intermittent exhaust, and therefore should not be modeled for compliance since it can't be matched in the baseline
    • Other bug-fixes - see Quick Start guide.

    • CBECC-Com 2016.2.1 has been approved by the California Energy Commission for Title 24 compliance.
