To study the efficient use of the housing and photovoltaic, we constructed housing which has adequate airtightness, adequate heat insulating efficiency, concrete floors, multiple window glasses for seasonal weather changes, and much more safety. We built a house in which two people can live (160 m 2 ) and which needs only 4.9 kW of energy. We did data analysis while they were actually living there.
As a result, we could create a comfortable environment in which to live, keeping the temperature in summer between 28.5 and 30 Β°C and the humidity 50% (moisture removal) and the temperature in winter between 22 and 24 Β°C and the humidity 50% (moisture addition). Because overdrying of the air was restricted, dew condensation was prevented. Of 4240 kWh, 2940 kWh (70%) became surplus electric power and the rest (30%) was consumed for a comfortable living environment. It was demonstrated that we could save 42% of electric power expenses compared with that of general housing (4-person household, 160 m 2 ) and that we could reduce by more than 60% the cooling and heating capacity.
