In order to clarify the situation of energy consumption and the indoor environment of an experimental house which was built for sustainable, measurements have been carried out since January 2006. The house is only occupied twice a year in summer and winter for a week. In order to predict the energy consumption and indoor environment of the house in line with the actual state of inhabited residence, simulation was carried out with the condition of a 4-person dwelt in the house. The following conclusions are drawn from this investigation: (1) The fluctuation of indoor temperature was minimal, especially in winter it is maintained constantly at 20℃; (2) Energy consumption of the house was found 0.8 times.
