The aim of this paper is to review the previous studies that employed the KPIs approach in buildings renovation for the measurement of the sustainability of the built environment. This work provides a brief foreword regarding the state of the art in building renovation projects, as well as the suitability of the application of the KPIs approach for the assessment of the level of sustainability in such projects and analyzes the results of the literature review. The future trends in building assessment methodologies for sustainability purposes are also presented, while some significant conclusions are also given based on the identification of the existing gaps of the specific field
