The purpose of this paper is to introduce a design method of environment-oriented house to optimize natural energy use such as natural ventilation and sun radiation throughout a year, by switching the combinations of several established passive design techniques as ‘Mode’. In this paper, according to the annual record of switching the modes by dweller with the measurement of temperature and energy, the cost of equipped architectural elements, contribution of workload by dweller, and the ratio of saving energy on air conditioning are evaluated as a reference.
