Purchasing process in shopping centers, are among the main issues in design and management of shopping centers, therefore the following research that is intended to determine the buyer 's needs and changes in space to meet the needs, has been developed. In this research , we accessed the person in the environment by using a experimental laboritical method and as a result to 155 people who centered in this place a question air and a form to report was given to record their opinions , which in them people tell their reason for shopping and the required conditions to purchase. By analyzing these issues , it is inferred that different factors will inference to process of purchasing which among them are feeling of security, calmness, anxiety. Therefore we could use the findings from the present research to increase the rate of purchase and transforming them to a full trading center for designing these shopping centers. By assuming that study of behaviors. In the users of these spaces , could offer approaches in design of shopping centers, these questions have been answered. By considering to the results from histograms, rate off effect of effective environmental factors on the purchasing process and also that much these factors are effective , was determined in this study. In this research , it was found that people have a large inclination to the their shopping at night , because in this time the existing environmental factors have the most influence on the shopping , singularly and recognize this process as a part of luxury , they wanted the auxiliary space beside shopping centers . so they can do other things such as eating. In this regard , these shopping centers did not have favorable environmental space and conditions and this is one of the weaknesses in this centers. For this purpose in designing the shopping centers we must consider to environmental factors such as security , attractiveness of space , environmental variations, and also in design of shopping cente
