本研究は、持続可能な住宅のグリーンプレミアムが長期エネルギー節約と炭素便益で正当化されるかを評価するCAHPVIを開発。30プロジェクトの分析で、グリーン志向物件が従来物件より高い指数スコア（平均0.628対0.494）を示し、平均プレミアム8.36%、エネルギー節約の現在価値平均4103万VNDを確認。エネルギー節約の重みが最大（0.246）で、適度なプレミアムと強力な省エネ証拠を持つ物件が上位に。高プレミアムで開示不十分な物件はグリーンウォッシュリスクを示唆。

This study develops a Carbon-Adjusted Housing Purchase Value Index (CAHPVI) to evaluate green premiums against long-term energy savings and carbon benefits. Analyzing 30 apartment projects (15 green, 15 conventional), green projects scored higher (mean 0.628 vs 0.494), with average green premium 8.36% and energy savings present value VND 41.03 million. Energy savings had the highest weight (0.246). Projects with moderate premiums and strong savings evidence ranked best; high-premium, weak-disclosure projects signaled greenwashing risk. CAHPVI offers a lifecycle valuation tool for buyers, developers, and policymakers.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではグリーンビルディング評価が進むが、グリーンプレミアムと省エネ効果のライフサイクル評価手法は参考になる。特に不動産投資におけるESG評価や、有報でのサステナビリティ開示強化の文脈で、本指数の考え方が応用可能。
In the global GX context
Globally, green building valuation often focuses on upfront costs. This paper provides a lifecycle-based index that integrates carbon benefits, relevant for frameworks like GRESB or EU Taxonomy. It addresses greenwashing by linking premium to energy performance disclosure.
👥 読者別の含意
🔬研究者:Provides a methodological framework for carbon-adjusted housing valuation that can be adapted to other markets or datasets.
🏢実務担当者:Offers a practical index for homebuyers and developers to compare green and conventional housing based on lifecycle financial and carbon benefits.

📄 Abstract（原文）
ABSTRACT Objectives: This study develops a Carbon-Adjusted Housing Purchase Value Index (CAHPVI) to evaluate whether the green premium paid for sustainable residential projects can be justified by long-term energy savings and carbon-related benefits. The paper aims to shift green housing evaluation from a static price comparison to a lifecycle purchase-value perspective. Methods: A composite-index approach was applied to a project-level dataset of 30 urban apartment projects, including 15 green-oriented and 15 conventional benchmark projects. The index integrates six dimensions: green premium, present value of energy savings, present value of carbon benefits, affordability pressure, operating cost, and green evidence disclosure. Indicators were normalized by benefit/cost direction, weighted using the Entropy-CRITIC method, and ranked through TOPSIS. Results: The findings show that green-oriented projects achieved a higher average CAHPVI score than conventional projects, with mean scores of 0.628 and 0.494, respectively. The average green premium was 8.36%, while the mean present value of energy savings reached VND 41.03 million per standardized unit. Energy savings received the highest final weight of 0.246, followed by affordability pressure at 0.224 and green premium at 0.213. Projects with moderate premiums and strong energy-saving evidence ranked highest, whereas high-premium projects with weak sustainability disclosure showed potential greenwashing risk. Conclusion: Sustainable housing value should be assessed through lifecycle financial and environmental benefits rather than upfront price alone. The CAHPVI provides a practical tool for homebuyers, developers, and policymakers to compare residential projects under a carbon adjusted and sustainability-oriented framework.
