📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では既存ストックの省エネ改修がカーボンニュートラル達成に不可欠であり、ZEB化は政府目標にも合致。本研究成果は、改修によるエネルギー削減量と投資回収期間の実データを提供し、日本の建築物省エネ基準や補助金制度の設計に示唆を与える。
In the global GX context
Globally, retrofitting existing buildings is critical for climate targets. This paper provides empirical evidence on energy savings, CO2 reduction, and payback periods, supporting policy frameworks like the EU's Energy Performance of Buildings Directive and LEED certification. It demonstrates a replicable approach for NZEB conversion in existing structures.

📄 Abstract（原文）
This work aims to reduce the energy consumption of existing buildings through retrofitting and converting them into net zero energy buildings (NZEBs). Various retrofits for an existing academic building were modeled and analyzed using REVIT software. Energy consumption was reduced to approximately 34% through retrofits, and a Solar System of 41.6 kW was integrated to meet the reduced energy demand, consequently converting the building into an net zero energy building (NZEB). Furthermore, environmental and economic analyses were conducted, and the results show a reduction of 32.8 metric tons of CO 2 emissions per year as a result of retrofitting the building, converting it into an net zero energy building. The building envelope retrofits and electrical appliances have a payback period of 2.96 and 2.62 years, respectively, whereas the proposed Solar System has a payback period of only 2.3 years. Moreover, the building was rated using the Leadership in Energy and Environmental Design (LEED) rating tool, and it qualifies for silver certification after retrofits and the integration of renewable energy sources (RES). The reduction in energy consumption and integration of renewable energy sources contribute to achieving Sustainable Development Goal (SDG) 7, and reduced CO 2 emissions save climate variations, which leads to achieving Sustainable Development Goal 13.
