A Framework for sustainable materials selection for high-rise buildings in Sri Lanka

Abstract

The construction industry, as a resource-intensive sector, significantly impacts the environment by consuming vast quantities of raw materials, energy, and water, while emitting substantial greenhouse gases and generating landfill waste [1]. Particularly, high-rise buildings are often associated with the consumption of significant amounts of energy and raw materials that result in negative consequences on the environment, economy, and society [2]. Consequently, there is an urgent need for sustainable construction practices, and the efficient use of materials plays a crucial role [3]. Hence this research aims to develop a framework to select sustainable materials for high-rise buildings in Sri Lanka. Sustainable materials in construction minimise environmental damage, protect raw materials from excessive depletion, and enhance long-term durability and efficiency of buildings [3]. The goal of these materials is to achieve a balance between environment, society, and economy without compromising the structural integrity and performance of the building [4]. The construction industry of Sri Lanka faces several challenges in the adoption of sustainable materials. One of the primary challenges is the lack of tools and data to sufficiently assess alternative materials to achieve sustainability in building [5]. In addressing this challenge, this research developed a framework to select suitable sustainable materials for high-rise buildings.
