本研究は、道路建設の複合施設（建設ヤード）の立地選定に再生可能エネルギー（RE）の自家消費（プロシューマー）を統合するGIS-MCDA手法を開発・実証した。ウガンダのブセガ・ムピギ高速道路を事例に、太陽光と風力の適合性を評価し、太陽光で最適な4地点を特定。既存施設と比較して8.3%のエネルギーギャップを回復でき、年間約120MWhの追加発電、USD 42,000-48,000のコスト削減、約84tCO2/年の排出削減が可能と試算。技術受容モデルによる評価では、建設段階でのプロシューマー導入への強い意欲が示された。

This study develops and demonstrates a GIS-MCDA method to integrate renewable energy prosumption into the siting of road construction compounds, using Uganda's Busega-Mpigi Expressway as a case. Solar suitability analysis identified four priority locations, with the best recovering an 8.3% energy gap, adding ~120 MWh annually, saving USD 42,000-48,000, and avoiding ~84 tCO2/year. Stakeholder evaluation via TAM showed strong adoption intention, while barriers like skills deficits and capital costs are transitional. The method is transferable to low-carbon construction in Sub-Saharan Africa and similar contexts.

日本のGX文脈において
日本では、建設現場の脱炭素化が急務であり、再エネ自家消費の導入が進むが、立地選定に再エネポテンシャルを組み込む手法は未確立。本手法は、日本の建設業界における再エネ統合の意思決定支援に応用可能で、SSBJやカーボンニュートラル目標への貢献が期待される。

📄 Abstract（原文）
The global transition to renewable energy (RE) is essential for sustainable development and climate change mitigation. However, integrating RE into road construction remains largely overlooked in both research and practice. Construction compounds—operational hubs for road projects, are energy-intensive; yet their siting is typically based on logistics, cost, and regulatory considerations, with minimal attention to onsite RE potential. This study develops, demonstrates, and evaluates a Geographic Information Systems-Multi-Criteria Decision Analysis (GIS-MCDA) method to identify optimal construction compound locations supporting RE prosumption, using Uganda's Busega–Mpigi Expressway as a case study. The method integrates constraint mapping with solar and wind suitability modelling using Weighted Linear Combination (WLC). Wind conditions (0.1–3.8 m/s; <4 m/s threshold) were infeasible, while solar analysis identified four priority construction compound locations (PCC1–PCC4), with PCC3 performing best, reflecting a distribution of 75% low, 21% moderate, and 4% high suitability classes. Sensitivity analysis confirmed robust spatial rankings across alternative weighting scenarios. Comparison with the existing compound revealed a recoverable energy gap of 8.3%, increasing annual output by ∼120 MWh, yielding USD 42,000–48,000 savings and ∼ 84 tCO₂/year avoided emissions. Stakeholder evaluation using the Technology Acceptance Model (TAM) showed strong intention to adopt (4.50/5.0) and support for construction-phase prosumerism (4.45/5.0). Barriers including skills deficits, institutional fragmentation, and high capital costs, are transitional and addressable through training, coordination, and procurement reform. Overall, the study contributes a transferable spatial method for RE-informed compound siting, extends prosumer theory to temporary project-based infrastructure, and supports low-carbon construction in Sub-Saharan Africa and comparable contexts.
