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.
