Analysing the significant factors for land use impact assessment in building construction projects in Sri Lanka: whole life cycle analysis approach

Abstract

This research paper focuses on analysing the significant factors for land use impact assessment in building construction projects in Sri Lanka using a whole life cycle analysis approach. The study recognizes the importance of land use in achieving sustainability and highlights the potential environmental consequences of land use changes and occupation. Through a questionnaire survey and the application of the Relative Importance Index (RII) method, the study identifies and ranks the key factors for land use impact assessment. The findings reveal that factors such as site selection, erosion and sedimentation control, site assessment and development, and on-site renewable energy play a crucial role in assessing the land use impact of building construction projects. A comprehensive assessment framework is proposed, which allocates credits to these factors based on their significance. The developed framework provides a practical tool for evaluating and promoting sustainable land use practices in the construction industry. The research underscores the need for considering land use impacts throughout the entire life cycle of buildings and emphasizes the importance of integrating sustainable practices into construction processes. By adopting the identified factors and assessment framework, construction projects in Sri Lanka can enhance their sustainability performance and minimize their land use impacts, leading to a more environmentally responsible built environment.
