Abstract
The purpose of this study is to investigate the energy consumption, power supply and demand of all-electrified net Zero Energy Houses (ZEHs). Energy measurement data of 67 all-electrified ZEHs was analyzed based on a nationwide survey conducted from 2018 to 2019. The primary energy consumption of all-electrified ZEHs was described in comparison with conventional houses. By analyzing the self-consumption rate, the self-sufficient rate, the amount of sales and purchase power, and the charging and discharging of storage batteries, it was inferred that most of the all-electrified ZEHs today are operated with profit as the objective, obtained by selling more electricity.
