本研究は、集合住宅における暖房・換気・給湯システムの脱炭素化指向型選定を提案。従来型と低炭素システム（ヒートポンプ＋再生可能エネルギー）を比較し、CO2排出削減とエネルギー消費低減を示す。初期コストは高いがライフサイクルコストで優位。SDGs目標7と11に貢献。
English
This study proposes a decarbonization-oriented selection framework for heating, ventilation, and domestic hot water systems in multi-family buildings. It compares conventional and low-carbon systems (heat pumps with renewables) using energy performance, economic, and environmental assessments. Results show significant CO2 and primary energy reductions with heat pump systems, though higher initial investment, with lower life-cycle costs. Aligns with SDGs 7 and 11.

📄 Abstract（原文）
The building sector is a major contributor to global energy consumption and greenhouse gas emissions, and multi-family residential buildings play an important role in urban decarbonization and the transition toward sustainable cities and societies. This study proposes decarbonization-oriented case studies for selecting heating, ventilation, and domestic hot water systems by integrating environmental, economic, and social criteria aligned with the Sustainable Development Goals (SDGs), particularly SDG 7 and SDG 11. This research compares selected conventional and low-carbon building-level heating, ventilation, and domestic hot water systems, including gas boilers and heat pumps integrated with renewable energy and heat recovery. The evaluation is based on a calculation-based energy performance assessment using a quasi-static monthly heat balance approach, economic indicator analysis, and environmental assessment based on primary, final, and useful energy demand and CO2 emissions. Cooling energy demand was not included in the assessment because the analyzed scenarios were limited to heating, ventilation, and domestic hot water preparation. Furthermore, the social implications are examined, considering energy affordability, long-term operating costs, and the potential to mitigate energy poverty. The results indicate that low-carbon HVAC systems, particularly heat pump systems integrated with renewable energy sources, significantly reduce CO2 emissions and primary energy consumption compared to conventional solutions. Although they require a higher initial investment, they can achieve lower life cycle costs over the building’s lifetime. The study concludes that holistic, decarbonization-oriented technologies can support cost-effective, socially responsible pathways toward low-carbon, energy-efficient multi-family residential buildings and sustainable urban development.
