Evaluating sustainable building practices: A systematic review of life-cycle assessment applications

This paper presents a comprehensive review of Life-Cycle Assessment (LCA) applications in building construction, a critical tool for evaluating and mitigating the environmental impact of the built environment. The study examines the evolution and current state of LCA methodology in the construction industry, emphasizing its pivotal role in promoting sustainable building practices. Through a systematic analysis of peer-reviewed literature and case studies, the review covers key aspects of LCA implementation, including energy use optimization, sustainable material selection, waste management strategies, and comprehensive environmental impact assessment across diverse building typologies and geographical contexts. The paper identifies and discusses significant challenges hindering widespread LCA adoption, such as data inconsistencies and methodological variations. Additionally, it explores emerging opportunities for enhancing LCA implementation, including integration with Building Information Modeling (BIM) and the development of standardized, user-friendly LCA tools. By synthesizing current knowledge and identifying research gaps, this review aims to guide future directions in LCA research and application, ultimately contributing to more sustainable and environmentally responsible construction practices globally.
