Recently, one of the most pressing challenges facing the construction industry is the inefficient use of resources, insufficient adoption of sustainable practices, and the environmental impacts caused by construction and demolition processes. In this context, modular buildings have emerged as a promising solution, offering advantages such as lightness, cost-effectiveness, design flexibility, rapid installation, and reusability. Particularly, the reuse of modular buildings presents a viable strategy to reduce construction waste and promote sustainable practices. However, significant challenges persist regarding the reuse of second-hand modular buildings, especially in terms of data availability, accessibility, and providing users with reliable information. This study aims to develop an automated evaluation and selection system for the reuse of relocatable modular buildings. The proposed system evaluates modular building alternatives based on customer preferences and facilitates user access via a web-based platform. As part of the study, thirty modular buildings were modelled in BIM environment, with key data such as service life, cost, environmental impacts, usage history, and location integrated into a BIM-based digital building passport. Additionally, multi-life cycle assessments were conducted, incorporating transportation-related carbon emissions into a comprehensive carbon budget formulation. Circularity performance was evaluated based on four key criteria defined by the ISO 59020:2024 standard: ecological impact, economic value, energy efficiency, and reusability. Using BIM and LCA data, these criteria were quantified and analysed through an MCDA method weighted according to customer priorities. This system supports user-oriented selection, aims to extend functional building lifespans, and contributes to environmental sustainability by reducing construction waste. Overall, the study proposes an innovative, data-driven digital assessment framework to enhance circular construction practices.
