Local Material Tectonics as an Aspect in Supporting Sustainable Architecture

Abstract

The construction sector is responsible for 39% of global carbon emissions, with 11% coming from embodied carbon materials. Local material tectonics has the potential to be a key aspect supporting sustainable architecture through optimizing the specific characteristics of local materials. This study analyzes the role of local material tectonics as a supporting aspect in achieving sustainable architecture goals in Indonesia. Through a qualitative approach with a comprehensive literature review and documentary case study analysis of three projects: Gando School Library Burkina Faso (local brick tectonics), Green School Bali (sustainable bamboo tectonics), and Bambu Indah Resort (bamboo-wood hybrid tectonics), this study identifies three main implementation strategies. First, material selection based on tectonic performance that considers thermal performance, structural efficiency, and local availability. Second, integration of climate-responsive construction details through natural ventilation systems and layered weather barriers. Third, the application of a modular-reversible system that supports long-term adaptability. The findings show that local material tectonics can reduce transport energy by up to 80%, increase durability by 2-3 times through climate responsiveness, and support the World Green Building Council 2030 target of 40% embodied carbon reduction. The research contribution is a theoretical framework that integrates the concept of classical Semper-Frampton tectonics with global sustainability targets in the context of local Indonesian materials. Practical implications include guidelines for implementing local materials for authentic and contextual sustainable architecture.
