Artificial intelligence and technology have enriched the physical environment and became an important part of humans' life. The digital reality has started to reform the human thought and to transform the urban setting. However, too few field researches related to the interaction between intelligent buildings, intelligent workspaces and people have been realized so far, a fact which has as a result the limited resources of information based on this scientific area. The bibliographical references on intelligent environments give emphasis more on their technological background and their facilities without examining enough the user's involvement. The goal of this article is to present aspects of user's behavior in the new spatial territories. The material is provided by a research that has been realized in two intelligent office buildings in Barcelona, Spain. Sixty (60) employees, thirty (30) men and thirty (30) women composed the sample. The collection of the data was made through questionnaires (questions of closed and open type) and was analyzed through qualitative and quantitative analyzing techniques. The basic parameters of the research are the spatial variables (technology, organization of space, location) and the social variables (organizational culture, gender), factors that play a significant role in employees' behavior. The analysis of the data shows differences between the two sexes in the way they comprehend the satisfaction in an intelligent working space and in the priorities they give on specific characteristics of the working environment (concerning its spatial organization and its technological characteristics). Also, there are indications that the location of the building and the organization culture of the companies influence the behaviour of both men and women. This project aims, through the study of employees’ behavior, to the formulation of design criteria which will contribute to the creation of a sustainable built environment and therefore to the improvement of the workspace quality.
