本レビューは、2021年から2025年までの2,658件の文献を質的統合と計量書誌分析により分析し、ネット・ゼロ・エネルギー・ビル（NZEB）研究の現状を包括的に評価した。結果、研究はエネルギー効率と再生可能エネルギーの統合に集中しているが、システムレベルの設計や実証検証が不足していることが明らかになった。蓄エネルギー、最適化、脱炭素化などの新興テーマは統合的アプローチへの移行を示すが、ライフサイクル評価や居住者行動、経済性、グリッド連携に重要なギャップがある。
English
This systematic review integrates qualitative synthesis and bibliometric analysis of 2,658 publications (2021-2025) on net-zero energy buildings (NZEB). Findings show research is centered on energy efficiency and renewable integration but lacks system-level design and real-world validation. Emerging themes like energy storage and optimization signal a shift toward integrated approaches, yet critical gaps persist in life-cycle assessment, occupant behavior, economic feasibility, and grid interaction.

日本のGX文脈において
日本では、2050年カーボンニュートラル達成に向けて建築物のZEB化が推進されており、本レビューは技術導入の現状と課題を整理し、政策立案や実務に示唆を与える。特にシステム全体の最適化やライフサイクル視点の不足を指摘しており、日本の建築GX戦略の強化に役立つ。
In the global GX context
Globally, buildings account for nearly 40% of energy-related CO2 emissions, making NZEB critical for climate neutrality. This review maps the fragmented literature and identifies gaps in system-level integration, real-world validation, and life-cycle thinking, offering a roadmap for future research and policy. It underscores the need to move from component-driven solutions to holistic, resilient frameworks.

📄 Abstract（原文）
Abstract Rapid urbanization and climate change are intensifying energy demand and emissions from the built environment, making them critical components of climate-neutral and sustainable cities. To address this challenge, Net-zero energy buildings (NZEB) are widely promoted as a promising solution. However, the existing literature remains fragmented across technologies, disciplines, and performance metrics, and thus limits a comprehensive understanding of NZEB pathways and their system-level implications. This study presents a comprehensive assessment of NZEB research by integrating qualitative narrative synthesis with quantitative bibliometric analysis of 2,658 publications from 2021 to 2025. The narrative review identifies key design strategies, technological pathways, and conceptual limitations, while the bibliometric analysis systematically maps thematic evolution, research trends, and collaboration structures. The results reveal that NZEB research is predominantly centred on energy efficiency and renewable integration but remains largely component-driven, with limited emphasis on system-level design, real-world validation, and cross-domain integration. Emerging themes such as energy storage, optimization, and decarbonization indicate a transition toward more integrated approaches; however, critical gaps persist in life-cycle assessment, occupant behaviour, economic feasibility, and grid interaction. The analysis also highlights the early-stage integration of digital and data-driven methods, underscoring the need for machine learning, uncertainty-aware modelling, and risk-informed optimization to address variability in climate and demand. These findings emphasize the need to transition from isolated technological solutions toward holistic, system-oriented NZEB frameworks that enhance scalability, resilience, and climate neutrality.
