Integration of advances in sustainable technologies for the development of the Sustainable Building Assessment Tool

Abstract

The construction sector is a resource-driven and resource-dependent industry. A rising global interest to incorporate sustainability principles in the policy-making means a careful balancing of economic growth with sustainability. To achieve this end in the Indian building sector, a triple-bottom-line-based building assessment tool like GRIHA and IGBC was introduced for assessing building sustainability. However, to revitalize the ideas of Reduce, Replace, Reuse, Recycle and Renovate (the ‘5Rs’) into implementable solutions, the technological dimension is introduced to form a quadruple bottom line (QBL) approach, i.e., social, environmental, economic and technological (SEET), for achieving sustainable construction. This study aims to address the necessity to add a new dimension, viz. technological advances in the sustainability arena of the construction industry. The objective of the study is to include technological advances in building materials, construction processes and techniques and design philosophies in the developed SBAT framework. In this extended and upgraded SBAT 2.0, advances in sustainability (AS) criterion accounts for 11.5 per cent showing its significance in achieving building sustainability. The use of discrete reinforcement, additive manufacturing, 3D printing, design based on packing density and rheological properties of concrete, use of alkali-activated materials in the mix-design and performance-based design concepts that affect future sustainability are successfully brought into the fold of SBAT framework.
