ガーナの不動産・建設業界の専門家400人への調査から、太陽光技術の効率性とスマートエネルギー管理が再エネ導入の最重要決定要因であることを示した。導入動機は長期運用コスト削減・炭素排出削減・エネルギー自立性向上で、障壁は政府支援の不足と初期投資の高さ。普及イノベーション理論に基づき、拘束力ある規制支援と財政インセンティブを実証・認証より先行させる政策順序を提言する。
English
Surveying 400 Ghanaian real estate professionals, this study identifies solar technology efficiency and smart energy management as the strongest determinants of renewable energy adoption in construction projects. Key drivers are long-term cost savings, carbon reduction, and energy independence; main barriers are weak government support and high upfront investment. Framed by Diffusion of Innovation Theory, it urges binding regulation and financial incentives ahead of demonstration and certification efforts.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本企業にとって直接の規制接点は薄いが、新興国での建設・不動産分野の再エネ導入障壁と政策順序は、海外事業の気候レジリエンス戦略やサプライチェーン脱炭素の参考になる。SSBJ・有報のScope3開示文脈では、海外建設案件の再エネ調達エビデンスとして補助的に活用可能。
In the global GX context
This adds Global South empirical evidence to the decarbonisation-of-built-environment literature, complementing TCFD/ISSB transition-planning debates with adoption barriers and policy sequencing from an emerging economy. It is relevant to global disclosure scholarship on how local institutional signals shape corporate renewable procurement and climate-resilience claims.

📄 Abstract（原文）
Climate change mitigation increasingly hinges on decarbonising the built environment, yet renewable energy integration in building construction remains underexplored in many emerging economies in Africa, including Ghana. This study examined the enhanced deployment of renewable energy sources (RES) in real estate projects as a contribution to climate change mitigation using the IDT approach. Using quantitative design methodologies, data was collected from 400 professionals working in the real estate industry, receiving a response rate of 94 %. Descriptive statistics, relative Importance Index (RII) and Multiple Linear Regression analysis were the tools deployed in the analysis. The results of the multiple regression analysis show that the most statistically significant determinants for the deployment of RES in developing projects are efficiency in solar energy technologies (β = 0.471, p = 0.000) and smart energy management systems (β = 0.247, p = 0.000). Additionally, the major factors triggering the adoption include reduction of long-term operational costs (mean = 4.65), reduction of carbon emissions (mean = 4.59), and improvement of energy independence (mean = 4.54). On the other hand, the main barrier for integration is the inefficient governmental support and lack of RES equipment in Ghana and high initial investments. Framed through the Diffusion of Innovation Theory, adoption is still concentrated among early adopters and innovators; the early and late majority have not yet been brought along, largely because the institutional signals (policy certainty, financial incentives, technical capacity and codified standards) that typically accelerate that movement are still underdeveloped locally. The study recommends that government and industry stakeholders prioritise binding regulatory support, targeted financial incentives, and solar-led implementation strategies, sequenced ahead of demonstration and certification efforts, to move renewable energy adoption from isolated examples toward standard construction practice.
