Abstract

Prefabricated bamboo construction offers a sustainable alternative to conventional building materials due to its low embodied carbon and rapid renewability. This study evaluates the environmental performance of prefabricated bamboo construction in Bali through a cradle-to-gate Life Cycle Assessment (LCA), incorporating both energy consumption and CO₂ emissions across material sourcing, processing, transportation, and manufacturing stages. Data collected from local manufacturers and combined with LCA databases indicate that a typical 50 m² prefabricated bamboo house consumes approximately 200 kWh of energy during production, primarily used in cutting, lamination, and assembly processes. Using the Indonesian national electricity emission factor of 0.7 kgCO₂/kWh, this translates to 140 kg of CO₂ emissions from energy use alone. When including all components, such as resin glue, steel connectors, and transport, the total net emissions were estimated at 252.5 kgCO₂, or 5.05 kgCO₂ per square meter. Notably, when accounting for bamboo’s natural carbon sequestration capacity (40 kgCO₂), the overall emissions dropped significantly, suggesting that bamboo construction can be carbon-neutral or even carbon-negative under optimal conditions. The findings highlight the importance of local supply chains, low-energy treatments, and renewable energy integration in maximizing the sustainability of bamboo-based construction systems. This research contributes a practical LCA framework for evaluating the environmental impact of prefabricated bamboo buildings in Bali and similar tropical regions.
