The following are features that must be installed as condition for meeting the modeled energy performance for this computer analysis.
• PV System: 5 kWdc• Battery System: 10 kWh• Insulation below roof deck• Non-standard duct location (any location other than attic)• Central parallel piping• Northwest Energy Efficiency Alliance (NEEA) rated heat pump water heater; specific brand/model, or equivalent, must be installed
HERS FEATURE SUMMARY
The following is a summary of the features that must be field-verified by a certified HERS Rater as a condition for meeting the modeled energy performance for this computer analysis. Additionaldetail is provided in the buildng tables below. Registered CF2Rs and CF3Rs are required to be completed in the HERS Registry
Building-level Verifications:• Quality insulation installation (QII)• Building Envelope Air Leakage• IAQ mechanical ventilation• Kitchen range hoodCooling System Verifications:• Minimum Airflow• Fan Efficacy Watts/CFMHeating System Verifications:• -- None --HVAC Distribution System Verifications:• Duct Sealing• Ducts located entirely in conditioned space confirmed by duct leakage testingDomestic Hot Water System Verifications:• -- None --

The estimated operating costs shown in this report are dependent upon many factors. The construction and conservation features of the project clearly are important. Equally important is the thermostat setting. How the thermostat is used, appliance use, and occupant interaction all influence the annual operating cost. The estimates provided in this report are based on typical conditions; your actual usage will vary.

WHERE THE ENERGY IS USED
This pie chart estimates the energy cost for the
various types of end uses in the home. Data has
been calculated using software that uses typical
profiles of usage to estimate end use cost. Your
costs may vary from these numbers depending
upon how the home is operated.
This all electric home was evaluated with QII and a significant solar system and battery included as well as mostfeatures needed to comply with the 2019 Title 24 code requirements.
