Housing is viewed as a collection of characteristics that are used to satisfy goals, such as comfort and visual quality. Identifying the most important functions of façadefaçade, results in improving quality. In this regard, the façade plays a crucial role in creating the borders of inner space in contact with its surroundings and can be considered as an interface. This study aimed to investigate and rank the most prominent functions of the façade in relation to the inside and outside of a home as a connector and barrier and find out the differences between the importances of façade functions of different indoor spaces of a home. The parameters were extracted through a theoretical study for the previous related studies, the functions of the façade were first investigated and categorized and then data was collected by using questionnaires completed by experts of housing design. The Delphi technique was used in this regard. In order to rankof the functions of a façade façaderegarding different interior spaces of the home, fuzzy TOPSIS technique, one of the approaches adopted in (MCDM), was used. Findings revealed that the key functions of the façade were sufficient daylight and good visual access for living room, control of natural ventilation and air flow for kitchen, privacy for the master bedroom and prevention of noise pollution and management of climate and natural disturbances for children bedroom. It also indicated that making connections with the outer space in the living room, kitchen, and hall are more important, however, in parents and children bedrooms, separation is significantly important.
