SOLAR HOT WATER SYSTEMS TO PREHEAT DOMESTIC HOT WATER
CRITERIA FOR QUALIFICATION Note: This measure is available for multifamily projects only.
I6.
Four points of credit are available for using only solar water heaters that are Solar Rating and Certification Corporation( SRCC) certified.
The solar water heater must be the primary heater. The system must serve at least 40 % of the hot water load, as calculated using F-Chart, other CEC-approved software, or a jurisdiction-approved calculation method.
A swimming pool solar water system does not satisfy this measure.
VERIFICATION
Field Verification: The Rater will conduct field compliance verification to confirm that the installed system meets the specified system, and take photos of the system.
Documentation: The Rater will collect building and / or mechanical plans detailing materials, systems, layout, and the performance percentage from F-Chart.
INTENT To conserve fossil fuels used for water heating by using renewable energy sources.
PHOTOVOLTAIC SYSTEM FOR MULTIFAMILY PROJECTS
CRITERIA FOR QUALIFICATION Note: This measure applies to multifamily projects only.
Up to twelve points of credit are available for providing a portion of the estimated annual electric energy demand with a solar photovoltaic system, as follows:

DRAFT
60 % of common area load— four points 90 % of common area load— eight points 10 % or more of the load for residential units— twelve points
Include all areas of the project built by the developer in the estimated demand. To calculate the energy contributions from the photovoltaic system, use calculations from the New Solar Homes Partnership Calculator, or from another CEC-approved calculation method. The estimate must include system size, expected output of the system, and an estimate of the amount of the total electrical load that will be offset by the photovoltaic system.
VERIFICATION
Field Verification: The Rater will conduct field compliance verification to confirm that the installed system meets the specified system, and take photos of the system.
