Evaluation of the effects of components improving the functional efficiency of space on improving people’s satisfaction; case study: houses of the first Pahlavi period of Shiraz

The concept of functional efficiency of the space in the architecture is related to the degree of coordination and coexistence of different elements of the space together to be able to respond to the wishes and needs of users and the possibility of performing different functions at different time intervals, which is of particular importance in the home. In this sense, the research aims to achieve an architectural and practical plan to guide the overall design process in an architectural format according to the concept of functional efficiency of the space, and to create a desirable residential architecture, and ultimately, improve people’s satisfaction. This research is applied research in terms of objective and descriptive non-experimental and case study research in terms of data collection method. The first goal is to prioritize the semantic indicators of the components that improve the functional efficiency of space on improving the satisfaction of people in the first Pahlavi period houses in Shiraz, and the second goal is to compare the importance of their effects with the average. Accordingly, due to the uncertainty of the exact number of statistical population, purposive non-probability sampling method according to Cochran's formula was used and 384 people were interviewed. The data were then transferred to »SPSS24« for data analysis, which was used to determine whether the data were normal or not from the Kolmogorov-Smirnov test. Friedman nonparametric test was used to achieve the first goal and univariate T-test was used to achieve the second goal. The results show that there is a significant correlation between the functional efficiency of space and satisfaction of people. Thus, the semantic indicators of the components that improve the functional efficiency of the space on improving the satisfaction of people in the houses of the first Pahlavi period of Shiraz should be considered by the architects so that the necessary arrangements can be implemented to achieve the desired residential architecture. Their effects are significantly above average.
