Abstract
\n\/\u6284\u9332<\/td>\n		Energy efficiency in the housing sector is important for achieving carbon neutrality; to achieve this, more net-zero energy houses (ZEHs) are required. ZEHs are considered resilient to\u00a0power outages<\/a>. However, the type of living that can be achieved during a power outage is unclear. The purpose of this study was to examine the\u00a0feasibility<\/a>\u00a0of staying in a ZEH with thermal comfort without a risk of heat stroke during summer power outages. We created daily schedules and conducted experiments using an actual ZEH assuming a power outage in summer. The experimental house was constructed in the suburbs of Shizuoka (about 110\u00a0km west of Tokyo), Japan, which has a humid subtropical climate. The house was equipped with a\u00a0photovoltaic system<\/a>\u00a0of 4.62\u00a0kW and a storage battery capacity of 5.6 kWh, which can output up to 2.0 kVA. The results showed that ZEH can provide air conditioning (AC), ventilation, lighting, refrigerator,\u00a0cell phone<\/a>\u00a0charging, televisions, and hot water supply for a 72-hour power outage. However, the use of high-load appliances and the use of bedroom AC during sleeping time caused disruption in the power supply. The use of AC on an independent circuit resulted in a predicted mean vote (PMV) of \u22120.5\u00a0\u223c\u00a00.8, and a wet-bulb globe temperature of approximately 23\u00a0\u00b0C was achieved. Thus, thermal comfort with a low risk of heat stroke was maintained. Solar shading and window openings were however not considered and further research is needed to evaluate more varied\u00a0architectural design<\/a>\u00a0and behaviors, and to assess the potential for staying at home in a ZEH. Different weather conditions and different occupant assumptions (e.g., elderly) also need to be further studied.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"
