本研究は、急速に成長する南半球の都市におけるポジティブ・エネルギー地区（PED）への戦略的アプローチを提案する。メキシコ・チワワの新規住宅開発を事例に、エネルギー効率対策と太陽光発電の同時導入により、年間76.9 MWhの正味エネルギー収支が達成可能であることを示す。しかし、厳しい気候変動シナリオ（SSP5-8.5）下では、2080年までにその正の収支が失われる可能性がある。
English
This paper proposes a strategic leapfrogging approach to Positive Energy Districts (PED) in rapidly growing Global South cities, bypassing building-level steps. Using Chihuahua, Mexico as a case study, it shows that combined energy efficiency and solar PV can achieve a positive annual energy balance of 76.9 MWh/year. However, under the SSP5-8.5 climate scenario, this balance is lost by 2080, establishing temporal limits.

日本のGX文脈において
本論文は、日本の都市におけるエネルギー自立地区の設計にも示唆を与えるが、主に途上国向けの戦略を提示している。日本のGX政策（ゼロカーボンシティ宣言など）との直接的な関連は限定的だが、気候変動の影響を考慮したエネルギー計画の重要性を再認識させる。
In the global GX context
This paper contributes to the global discourse on urban energy transition in the Global South, highlighting the potential and limits of PEDs under climate change. It provides quantitative benchmarks relevant to climate disclosure frameworks and transition finance for city-level decarbonization.
👥 読者別の含意
🔬研究者:Researchers studying urban energy systems and climate adaptation will find the quantitative benchmark and climate scenario analysis valuable.
🏢実務担当者:Practitioners in urban planning and energy management can use the leapfrogging approach and efficiency measures as a template for similar contexts.
🏛政策担当者:Policymakers in developing cities can consider the PED concept as a viable starting point, but must account for climate change impacts on long-term viability.
📄 Abstract（原文）
The transition toward Positive Energy Districts (PEDs) represents a crucial strategy for achieving climate neutrality at the urban scale. For rapidly growing cities of the Global South, however, advanced concepts like Net-Zero and Positive Districts rarely appear on planning agendas. Leveraging experience from the Global North, this paper explores a strategic “leapfrogging” approach that bypasses intermediate building-level steps to focus directly on simultaneous implementation of energy efficiency measures and renewable energy generation at the district level. The case study analyzes a new residential development in Chihuahua, Mexico, a rapidly growing city in an arid climate. This brief research report establishes a quantitative benchmark for PED viability using urban building energy simulation to model current annual energy demand and estimate maximum achievable solar photovoltaic generation based on available surfaces. The analysis calculates the minimum demand reduction needed through efficiency retrofitting to close the energy gap and achieve positive energy balance. Additionally, the study explores energy demand and solar potential under future climate scenarios. Results show that baseline demand of 1,536.8 MWh/year can be reduced through key efficiency measures, and combined with technically achievable solar systems, achieves a positive balance of 76.9 MWh/year. However, under a critical climate change scenario (SSP5-8.5), the positive balance would be lost by 2080. This establishes both the viability and temporal limits of PED implementation in arid, rapidly growing Global South contexts.
