Abstract
To study the efficient use of the housing and photovoltaic, we constructed housing which has adequate airtightness, adequate heat insulating efficiency, and concrete floors, multi-ple window glasses for seasonal weather changes and much more safety. We built a house where tow people can live(160m2) 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 to live, keeping the temperature in summer between 28.5 and 30°C and the humidity 50%(moisture removal) and the temperature in winter between 22 and 24°C and the humidity 50%(moisture addition). Because over drying of the air was restricted, dew condensation was prevented. 4240 kWh out of 2940kWh (70 %) became surplus electric power and the rest (30%) was consumed for a comfortable living environment. It proved that we could save 42% of electric power expenses compared with that of general hausing (4 person household, 160m2) and that we could reduce more than 60% thecooling and heating capacity.
