本研究は、スイスの住宅ストック全体を表す11,200の建築類型を組み合わせ、電化シナリオ別にポジティブエネルギー比率、自給率、自家消費率、太陽光余剰時間を評価する枠組みを開発。ほとんどの戸建て住宅は電化回避時に正の電力バランスを達成できるが、集合住宅は電化なしでもネット消費者であることを発見。政策提言として、個別の電化経路と余剰エネルギー充電を推奨。
English
This study develops a framework combining 11,200 building archetypes to simulate the Swiss residential stock's energy balance, evaluating key indicators like positive energy ratio, self-sufficiency, and self-consumption under different electrification scenarios. Findings show most single-family homes can achieve positive electricity balance without electrification, while multi-family homes remain net consumers even without electrification. Recommendations include tailored electrification pathways and surplus energy charging policies.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
スイスの住宅ストックに特化しているが、日本の戸建て中心の住宅地や集合住宅への応用可能性を示唆。日本でも地域エネルギー自立（類似のPED概念）が注目されており、建築類型別のシミュレーション手法は参考になる。
In the global GX context
This paper advances the global understanding of Positive Energy Districts by providing a granular simulation framework for diverse building types. While focused on Switzerland, its methodological approach can inform similar analyses in other countries, especially for urban energy planning and electrification strategies.

📄 Abstract（原文）
The concept of Positive Energy Districts (PEDs) has emerged to facilitate the energy transition and contribute to climate neutrality through energy efficiency and a net-zero energy balance. These districts are meant to integrate a variety of technologies with the goal of producing more energy than they consume, while also actively involving residents in decision-making processes and enhancing affordability. However, a significant barrier to the widespread deployment of PEDs is uncertainty surrounding the potential benefits of this concept, particularly given the diverse range of building stock and technologies involved. Addressing this uncertainty is crucial for unlocking the full potential of PEDs and ensuring their successful implementation in urban environments. We developed a framework that represents the entire residential building stock, along with electricity production and consumption on an hourly basis, by combining 11,200 archetypes to represent key indicators such as positive energy ratio (PER), self-sufficiency rate (SSR), self-consumption rate (SCR), and PV hours of surplus under different electrification scenarios. This framework considers the full exploitation of the PV potential on residential buildings and current energy consumption levels for heating and mobility. Given our findings that most single-family houses (SFHs) can achieve a positive electricity balance when electrification is avoided, while multi-family houses (MFHs) remain net consumers even without electrification. Overall, increased electrification leads to lower SSR and higher SCR. However, in high-rise MFHs, electrification does not improve SCR. Given their relevance as critical building archetypes, we recommend PED strategies that emphasise tailored electrification pathways, surplus energy charging, and targeted policy interventions.
