In order to improve the climate in the atrium of a school building, CFD techniques have been applied. The current simulation has been simulated and appears to be in adequation with onsite measurements. Modifications of cross ventilation, outside sun blilnds and floor cooling have been studied for a further renovation.

Air conditioning in passenger car is an important part of the modern train technology. The induction unit (IDU) - the terminal equipment of induced draft system - is studied in this paper. Some experiments were done to investigate its characteristics including fluid field of return air inlet and supply air outlet, velocity decrease of supply air outlet resistance characteristic and induction ratio.

The population epidemic investigation method was used for that study in order to investigate the relationship between human uncomfortable feeling symptoms and indoor air conditioning thermal environment. Results are presented.

Korean gouvernment supports researches to improve indoor air pollution. For that study, an investigation was conducted on indoor concentration of chemical pollutants, passive flux from building materials, ventilation rate, temperature and relative humidity. A passive measurement method developed by the authors was used.

For that study field VOC measurements were conducted in 20 natioanl hospitals in Japan. Passive samplers were used. Results are presented .

This paper describes an investigation of the indoor environment in Dutch daycare centers. Air temperature and CO2 levels measurements were made during summer and winter in 14 centers.. Results and recommendations are presented.

Recently, the Indoor Air Quality Management Act came into effect in Korea., in order to limit formaldehyde and VOCs concentration levels in new buildings. For that study , six residential units were tested under different conditions : air-cleaning and ventilation effects were evaluated . A comparison of the applicable strategies was made to improve indoor air quality at the pre-occupancy stage of inhabitants.

For that study, indoor air pollutants including CO2, CO, MP10, PM2.5 and volatile compounds were measured in four hot spring hotels, (the results are presented.

The investigation and analysis of indoor environment condition of high and middle grade office building is presented in this paper, along with the results

Pressure coefficients are considered vital components for the calculation of airflow through opening in building.The experimental investigation consisted of a square wind catcher connected to a model test room. At various wind speeds and four different wind directions between 0-45 at interval of 15, the pressure coefficients distribution, the internal air speed and the volumetric airflow were measured.The results obtained using Explicit, AIDA Implicit model and CFX code appeared in adequacy with the experimental results at lower speeds and with wind incidents at angle of 0-15 .
