イタリアの住宅建築類型を対象に、ローマとトリノの2気候区で緑化ファサードの省エネ・気候適応効果をEnergyPlusで評価した研究。改修前建物では冷房需要を最大59%、過熱を85%削減し、断熱等の改修後でも冷房24.7%・過熱54.8%の追加削減効果を示す。気候変動により相対効果は低下するが2090年代でも有効で、夏季負荷の大きいローマで効果が高い。
English
Using EnergyPlus, this study models green façades on a representative Italian residential archetype in Rome and Turin under 2020s–2090s climate scenarios. Green façades cut cooling demand by up to 59% and overheating by 85% in pre-retrofit buildings, and add up to 24.7% cooling and 54.8% overheating reductions beyond standard retrofit packages. Benefits decline with warming but persist through the 2090s, with larger gains in hotter Rome.

日本のGX文脈において
日本の建築物省エネ法やZEH・LCCM住宅、都市のヒートアイランド適応策を考える上で、緑化ファサードの定量的効果と気候変動下での限界を示す参照事例となる。特に改修パッケージとの組合せ効果は国内の既存ストック改修政策に示唆を与える。
In the global GX context
Adds quantitative evidence on passive adaptation measures to the global building-decarbonization and climate-resilience literature relevant to EU EPBD retrofit mandates and CSRD/TCFD physical-risk disclosure. It shows green façades as a complementary, not substitute, measure alongside insulation and shading under future warming.

📄 Abstract（原文）
Accounting for 32% of global energy consumption, buildings not only impact climate change but are also affected by it. To address these challenges, in addition to decarbonising the building stock, there is a need to implement climate-resilient solutions that enhance climate adaptation. The proposed study explores the energy efficiency and climate resilience of non-traditional solutions like green façades for a representative Italian residential building archetype in two distinct climate zones, Rome and Turin, under current (2020s) and projected (2050s and 2090s) climate scenarios. The green façade is analysed using a detailed calculation tool implemented within the EnergyPlus (version 23.2) energy simulation software. The analysis covers both existing buildings without insulation and buildings retrofitted with insulation, solar shading, and ventilative cooling. Results indicate that green façades—particularly when applied to multi-orientations of the building—can significantly reduce cooling need and overheating in pre-retrofit buildings, with reductions of up to 59% and 85%, respectively. In retrofitted buildings, green façades offer additional benefits beyond standard retrofit packages, with further cooling need reductions of up to 24.7% and decreasing overheating by up to 54.8%. Although their relative effectiveness generally declines with climate change due to rising temperatures and reduced plant evapotranspiration, green façades continue to provide relevant benefits even under the 2090s scenario. A comparison between the two climate zones reveals greater cooling reductions in Rome due to higher summer heat loads and lower winter heating penalties. These findings underscore the green façade potential as a passive design strategy to support the transition towards more sustainable and climate-resilient residential buildings.
