The Domestic Hot Water boiler you have input in the DHW/Boiler library has a Standby Loss value set to zero. The CEC requires a value for this type of water heater be entered that is greater than zero.
Check to make sure you intended to enter this type of water heater. Smaller, more common federally regulated water heaters do not require this input.
You can obtain this value from the manufacturer or from the CEC Appliance directory at www.energy.ca.gov. Click on the Libraries button on the bottom left. Select the DHW/Boiler Library in the list that appears above. Now find your water heater and enter the Standby Loss value.
