An Analysis on Life Cycle Assessment and its impact on Environmental and Economic Perspectives

Rapid urbanization and population growth in Bangalore have significantly increased the demand for residential buildings, leading to environmental and economic challenges. To address these issues, integrating sustainability principles into the construction industry is essential. This research comprehensively analyses the environmental and economic sustainability of residential buildings in Bangalore using the Life Cycle Assessment (LCA) methodology. The study began with an extensive literature review to identify key sustainability indicators for residential buildings. A multi-faceted data collection approach was employed, including on-site measurements and surveys with contractors and residents. Data were gathered from residential projects such as Prestige Group, Brigade Gateway, and Puravankara Magadi Road. The collected information was analyzed to assess the environmental impact and economic feasibility of buildings across their life cycle—from raw material extraction to construction, operation, and end-of-life phases. Reliability and validity tests, including Cronbach’s Alpha and KMO, were conducted using the JMP software tool. By integrating LCA with economic evaluation techniques, the study quantified sustainability indicators and identified key areas for sustainable interventions. The findings provide valuable insights for developers, architects, and residents, serving as a decision-support tool. Additionally, the research contributes to sustainable development policies and guidelines for future residential projects in Bangalore and other urban areas facing similar challenges.
