Abstract |
In these days, constructions of atria using glasses are rapidly increased. Buildings with an atrium have not only cultural, economical and functional benefits for space but also friendly visual impressions to occupants. But there are various problems can occur such as overheating in summer, excessive vertical temperature difference, condensation, diffusion of noise and echo and withering landscapes. Especially, vertical temperature difference is important for the estimation of cooling or heating load yet, there are little studies being done. In this study, indoor air temperature was measured vertically and analysed. From this measurement, it is found that the variation of temperature is more irregular by low outdoor air temperature, when the height is lower. Also, when the height is higher, the variation of temperature is more fluctuated wildly by the solar radiation and the buoyancy of air in daytime. As a result, the relationships of the vertical temperature difference with height and solar radiation is analysed and suggested. |
