N2  - A solar chimney system was established in Adıyaman University campus area designing a special layered soil (27 m diameter and 0.5 m deep drop-circular hole, while the aluminum foil, glass wool, sand, gravel, broken glass trotters windscreen and its top surface, asphalt) on the 0.004 m thick glass laying the panels, 17 m height of 0.8 m in diameter chimney and a height adjustable air inlet collector (periphery) from 0.05 to 0.35 m to investigate the effect of environmental temperature, chimney height, the collector diameter, the value of solar radiation etc on the performance or effectiveness of Solar Chimney (SCS). In this study, on July 22 on 13:00, temperature, air velocity and temperature under collector at point C2 for different heights (0.05 – 0.35 m) for air inlet portion of collector (periphery) and of special prepared ground floor according to weather conditions (solar radiation, ambient temperature, air velocity) is investigated. Moreover, temperature of ambient, under collector, glass surface and ground under collector along the day with two hours interval and ambient air velocity, temperature and air velocity at point C2 where turbine is assembled is investigated. Measurements made in the collector air inlet height is now long solar chimney performance dropped the most ideal height 0.05 m, the specific configuration of the ground daily solar radiation and ambient temperature proportional to a heat store and heat it to the night collector environment by giving the system performance increase was observed. Solar chimney 'of the ground under the collector of solar radiation absorption rates to the performance of the system efficiency can be considered as a parameter. It is observed in the measurements that as long as the collector air inlet height increases, solar chimney performance dropped and the most ideal height becomes 0.05 m. Also, the specific configuration of the ground daily solar radiation and ambient temperature proportional store heat and it increases the performance of the system by giving this heat to the collector environment in evening. Solar radiation absorption rate of ground under the collector in solar chimney should be considered as a parameter that affects efficiency performance of the system
