Super tall building has many advantages but also has some problems such as stack effect. Stack Effect is a general phenomenon that arouse in a building. However, the building height is higher and higher, a lot of air flow into building and moved to the upper part of the building and cause a variety of problems. On the while, many super tall buildings were made and planned in the world and korea in these days. So we need to understand the stack effect in super tall buildings and make a counter measures to mitigate the stack effect. The purpose of this study is to grasp the characteristics of stack effect in super tall building through numerical simulation. In this paper, the characteristics of stack effect for super tall building(100 floors) are compared to those of high-rise building(43 floors). Moreover, the wind effect on stack effect will be analyzed.

For analyzing energy consumption in building sector, the building simulation method is actively used in these days. Among input-data in building simulation, typical weather data is required for simulating external-environment. Direct-diffuse insolation data are needed for producing typical weather data. However, direct-diffuse insolation data are rarely measured in the world, most countries generate the direct-diffuse insolation data with prediction model. In this study, 4 direct-diffuse insolation decomposition models(Perez, Watanabe, Erbs, Reindl-2) are selected for assessing the applicability in domestic 5 regions of sky conditions. MBE, CVRMSE, Adjusted R square and multiple-correlation methods are applied in assessment. Watanabe model and Reindl-2 model show high accuracy among the 4 prediction models. In cloudy(Ad-R:0.67-0.59) and clear (Ad-R:0.45-0.31) sky condition, accuracy showed high. In multiple-correlation method, Watanabe model and Reindl-2 models are analyzed from sky condition. The Watanabe model shows high tendency between error value and meteorological factors (horizontal insolation and solar angle). There is no dominant prediction model from the applicability result. However, Watanabe model showed high applicability in domestic regions with the adjusted regional coefficient according to sky condition.

The existing cooling system can not satisfied the human thermal need as compared to the natural breeze in country side where located near mountains and river side. Why don't we feel comfortable? This difference can be described by the fluctuation characteristics of natural wind. The natural wind fluctuates all the time in all directions and we can not recognize its behaviors. If the fluctuation characteristics of natural wind would be generated with existing cooling system, it could be a comfortable wind for us. In this study, the characteristics of natural wind will be analyzed through chaotic analyzing methods and will be compared to the mechanical wind. In this paper, the field measurement for natural wind which accomplished at near mountain in summer will be reported. Moreover the characteristics of mechanical wind will be analyze through laboratory experiment. Finally, the Chaotic Phenomena of Natural Wind and Mechanical Wind will be described.

In this study, the effects of blind on indoor radiant heat loss and winter heating loads were analyzed by simulation. The amount of radiant heat reflection of the blind was analyzed in three rooms with different window shading conditions. Also the winter heating load according to the properties of the blinds were analyzed. The results are as follows; (1) In the case of installing the high reflective blinds (Cell #3), the reflected radiant heat was about 4.25 times compared to the case without no blinds (Cell #1) and 2.43 times compared to the existing venetian blinds (Cell #2). (2) The total heating load of Cell #3 was reduced by about 17% compared to Cell #1 and 13% compared to Cell #2. This is because the high-reflective blind of Cell #3 has the highest reflectance of 0.86, so it is considered that the radiant heat generated indoors is almost reflected toward the indoors, and this result in a reduced heating demand in Cell #3.

The university classroom is one of the most vulnerable places for high density particulate matter(PM). University classroom is often enclosed for blocking the ambient noise during the class, more than 1 hour, and almost university buildings do not have a ventilation system or air purification system. In addition, the number of students per classroom in university is higher than other space. As a result, PM concentration in the classroom can be higher than the domestic standard. The purpose of this study is to investigate the relation between the factors affecting the PM concentration in the university classroom by long-term field measurement. Indoor PM concentration will be measured in three classrooms and outdoor PM will be measured on the roof of the building. Factors affecting the indoor particulate matter concentration such as cleaning, window and door opening status, number of occupants and its movement, and air conditioner operation status will be monitored. In this paper, the ongoing measurement results will be presented. The measurement results as follows; the PM concentration in the classroom showed high concentration when the occupancy density when the lecture was high and natural ventilation was not performed. However, in the lecture room with low occupancy density, the particulate matter decreased even though natural ventilation was not occurred.
