Abstract

The building industry consumes a significant amount of energy due to various factors such as building facade, floor area, energy resource demand, temperature variability, and construction and usage practices. Construction envelopes and the efficiency of building energy demand and equipment contribute to increased energy consumption. Different envelope materials are available, each with different environmental impacts. This research aims to establish a decision-making framework for selecting appropriate building envelopematerials. This paper focuses on conducting a life-cycle assessment (LCA) over a 50-year period for two envelope systems in Indian cities. It considers factors affecting the life cycle assessment of residential buildings, including construction, maintenance, and operational aspects of the building envelope systems. Evaluating building envelope performance is essential for reducing residential energy consumption and maximizing the quality of envelope materials through the application of LCA. The research outlines a comprehensive and systematic approach for selecting building envelopes, providing valuable insights for decision-making regarding envelope materialswith maximumefficiency for residential construction.
