セルビア・ノヴィ・ベオグラードの築40年超ラメラ型集合住宅2棟を対象に、断熱・屋上緑化・屋上太陽光の3改修シナリオを動的シミュレーションとLCAで比較した。断熱と緑化は暖房需要を27〜31%、ライフサイクルGWPを10〜13%削減しほぼ同等、太陽光はGWPを最大26%削減するが資源枯渇や水・土地利用を増やす。効果は屋根面積比に依存し低層棟で有利となる。
English
This study compares three retrofit pathways—insulation, extensive green roof, and rooftop PV—for two 40+ year-old lamella residential buildings in Novi Beograd, Serbia, using calibrated dynamic simulation and cradle-to-use LCA. Insulation and green roof cut heating demand by 27–31% and lifecycle GWP by 10–13%, while PV achieves the largest GWP reduction (up to 26%) but raises resource depletion and land/water use. Benefits scale with roof-to-floor ratio, favoring lower-rise buildings.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の集合住宅ストック（団地・UR賃貸等）の脱炭素改修や屋上活用の検討に、LCAベースの比較手法として参考になる。ただしSSBJ・有報・統合報告書など開示制度との直接接続はなく、実務では改修投資判断の材料としての位置づけに留まる。
In the global GX context
Adds a comparative LCA evidence base for retrofitting post-war residential stock, relevant to EU building decarbonization and renovation-wave policy. It does not engage TCFD/ISSB/CSRD disclosure frameworks, so its global disclosure-scholarship contribution is indirect—useful mainly for physical transition planning and building-level climate metrics.

📄 Abstract（原文）
This paper evaluates the energy performance and lifecycle environmental impact of three retrofit pathways—conventional insulation, an extensive green roof, and rooftop photovoltaics—for two lamella-type residential buildings (three-story, five-story; over 40 years old) in Blocks 45 and 70, Novi Beograd, Serbia. The study builds on an architectural concept treating the flat roof as an active environmental surface. Energy demand was quantified via calibrated dynamic simulation for a baseline and three scenarios—insulation (S1), insulation with an extensive green roof (S2), and insulation with rooftop photovoltaics (S3)—with environmental performance assessed using cradle-to-use LCA (1 m2 heated floor area, 50-year period) covering global warming potential, cumulative energy demand, and Environmental Footprint 3.1 indicators. Insulation and the green roof achieve nearly identical reductions in heating demand (27–31%) and lifecycle GWP/CED (10–13%), the green roof performing marginally better while also offering evapotranspirative cooling and urban co-benefits. Photovoltaics deliver the largest lifecycle GWP reduction (26% three-story, 15% five-story) and cut acidification by up to 36%, but increase mineral resource depletion, water and land use. Benefits of both roof-level measures scale with roof-to-floor-area ratio, favoring lower-rise buildings, supporting prioritization of green roof and photovoltaic retrofit across the district lamella stock.
