本研究は、インドネシアの住宅建築において、木材（グレードラム集成材）を使用した場合の環境便益を分析。BIMと産業連関分析を用いて、従来の鉄筋コンクリート、ハイブリッド、木造の3シナリオを比較。ハイブリッドで16%、木造で31%の埋め込みエネルギー・CO2削減を確認。国産材は輸入材より炭素貯蔵効果が高い。
English
This study analyzes the environmental benefits of using wood materials (Glulam) for residential construction in Indonesia. Using BIM and input-output analysis, it compares embodied energy and CO2 across conventional RC, hybrid, and wooden scenarios. The wooden scenario achieves 16% and 31% reductions in embodied energy and CO2, respectively. Domestic wood species store more biogenic carbon than imported alternatives.

📄 Abstract（原文）
The building sector is responsible for 39% of GHG emissions resulting from the world energy consumption and for 25% of the residues worldwide, thus, any effort in tackling its environmental impact is important for climate change adaptation. Wood offers more sustainable building materials, and unlike reinforced concrete (RC) or steel, wood production and use require less energy and release less CO2. This research analyzes the environmental benefits of Glulam (Glue-laminated timber) and wooden materials for residential construction in Indonesia, studying three building scenarios: a conventional study case (RC), a “hybrid” scenario, and a “wooden” scenario. Building Information Modeling (BIM) was used to calculate the bill of quantities (BoQ), then, embodied energy (EE) and embodied CO2 (ECO2) emissions among the three scenarios were compared, using a hybrid-based input-output (I-O) analysis utilizing the latest available national level Indonesian I-O 2024, and data from an Indonesian Glulam manufacturer. This study found an EE & ECO2 decrease of around 16% in the hybrid scenario, and 31% in the wooden scenario, when compared with conventional construction. Using Glulam and wooden materials contributed to foundation material optimization and the best alternative for biogenic carbon storage was domestic species, which stored more carbon than imported alternatives.
