Characteristics of indoor thermal environment and air-conditioning load in atriums with openings were studied using a simplified prediction model. Influence of draft airflow through openings was modeled using the result of CFD analysis, and the model was improved to investigate indoor thermal environment with natural ventilation. Difference of thermal distribution and air-conditioning load were studied under several conditions, and the most effective condition for energy conservation was investigated. Finally, a periodic control method of openings was suggested. In this method, outside air will be adaptively introduced according to the outside temperature and intensity of solar irradiance. As the result of thermal load prediction through a year, it was found that this method is effective to reduce thermal load or a long priod during spring to autumn, and more than 20 % of yearly air-conditioning energy will be reduced.
