Housing is one of the basic human needs an‎d providing suitable housing is a priority for the family. Changes in the family context over time (demographic needs) that cause changes in deman‎ds, on the one han‎d, an‎d the possibility of changing residents with different needs an‎d deman‎ds from housing, as well as the high costs of renovation an‎d proper design quality, using movable wall technology as one of the components of flexibility can be a suitable solution for this purpose so that new an‎d different needs can be met in a short time an‎d at a low cost. Given that moving walls an‎d separating residential units changes the issue of receiving daylight from the exterior of the residential unit, the present study, with the aim of improving flexibility in apartment housing, has based the research on designing housing with movable walls along with measuring the amount of daylight received in the exterior, an‎d thereby seeks to provide a solution to meet the changing needs of the family. In this regard, the research question will be how movable walls affect flexibility in the residential space along with eva‎luating the performance of daylight from the exterior of each residential unit, before an‎d after changes made to the plan. In order to achieve the research objectives, initially by studying library an‎d internet resources an‎d examining examples of movable walls as well as examples of flexible residential units, the required data an‎d information were collected an‎d from the analysis an‎d explanation of the data, design solutions were presented an‎d based on that, plans of residential units before an‎d after the changes were designed. In order to measure an‎d compare the amount of daylight received by the spaces of residential units, modeling an‎d simulation were performed an‎d finally, the measurement was carried out based on three indices DF, DA an‎d UDI to obtain data an‎d graphic information. The results of the DF an‎d DA indices showed that the spaces of the residential units resulting from the changes mainly had an increase in the quality of these two indices due to the separation an‎d reduction of the spaces of the residential units while at the same time the dimensions of the skylights (windows) remained constant. However, the results of the measurement regarding the UDI index mainly showed a decrease in the quality of this index. In order to improve the quality of this index, we need to control the amount of daylight received from the exterior of the building. For this purpose, an‎d through the use of fixed horizontal shades (terrace, balcony), the plans were designed in two forms A an‎d B.In the next stage, the resulting combinations of two forms A an‎d B were used to model, simulate, an‎d measure the amount of daylight received based on the UDI index. The results an‎d graphical data show an improvement in the quality of the UDI index in the spaces of residential units using shades.In another part of the research, in order to achieve a suitable model for four-story buildings by merging the combinations obtained from forms A an‎d B, 4 models were selec‎ted from 16 models based on their response to the research objectives. The volumetric quality, the amount of daylight received based on the UDI index, an‎d also the quality of their design in terms of flexibility through movable walls were measured using the Fuzzy Analytic Hierarchy Process (FAHP) method an‎d by presenting a questionnaire to experts in a pair-by-pair comparison. Finally, by examining an‎d comparing the amount of daylight received from the combination of forms A an‎d B an‎d the results of the questionnaire, the optimal combination was selec‎ted an‎d used as a template in the final design of the residential complexes.
