Abstract
The sunspace is a kind of passive solar design method commonly applied to the architecture in area of the frigid zone or the temperate continental climate zone. Sunspace not only can reduce the cooling load of the building effectively in winter through the greenhouse effects, but also have a lot of other additional value too. But to Taiwan of the subtropical area, because it is the hygrothermal climate, how the sunshine room is suitable for the building of Taiwan is a important question to research. How to choose orientation and glass of the sunspace should be the main subject for research. The numerical simulation utilizes Ecotect software to calculate the temperature of the sunspace of ' N.T.U. Smart Home' by the admittance method as the foundation theory. Besides, the real temperature is obtained by actual measurement method in different seasons, in order to compare with simulation result.
The result of research shows 1. After comparing actual measurement with simulation result, the analysis result proves admittance method really can simulate the temperature of the sunspace effectively. 2. For the sunspace cooling load in the daytime of summer, it should be controlled effectively through some of thermal insulated or exhausted facilities. The influence that the low temperature causes is not obvious in winter. The sunspace can still store heat effectively. 3.Under the geographical location and climatic conditions in Taipei, the best orientation of the sunspace is NNW（azimuth 337.5°）, and it is recommended that northward to westward is also good choice range.
