Abstract
Because of the remarkable interest in preserving the architectural heritage of the Kingdom of Saudi Arabia and the emergence of multiple models of adaptively reused heritage buildings in the historic Jeddah area, it is necessary to ensure their correct usage, periodic evaluation, and sustainability. This study develops a model for evaluating the adaptive reuse of historical buildings to preserve their integrity and originality. It adopts a qualitative approach and analyzes references and charters, as well as classifications and methodologies associated with the adaptive use of heritage buildings. The model consists of two main axes. The first includes the basic information on the building, and the second includes elements and criteria for reuse, restoration, and repair, as well as intangible elements of the cultural heritage that can improve people's livelihoods. It was judged by five architectural heritage specialists in the region to ensure comprehensiveness. This study will draw the attention of those responsible for preserving heritage buildings toward the need for the periodic evaluation of buildings, which can be done through use of the model, to ensure the authenticity and sustainability of historical buildings during reuse and determine if activities should continue or be halted.
