本論文は、トロントの集合住宅を対象に、現地調査、サーモグラフィ分析、ベンチマーキング、eQuestシミュレーションを組み合わせた体系的なエネルギー監査手法を開発・適用した。暖房と電力が主要なエネルギー消費・排出源であり、フルレトロフィットにより年間約25%（1,100 tCO₂e）の排出削減が可能であることを示した。分析結果と解釈を分離することで意思決定を強化し、既存集合住宅の脱炭素化戦略の優先順位付けに貢献する。
English
This paper develops and applies a structured energy audit methodology for a multi-unit residential building in Toronto, combining site inspections, thermographic analysis, benchmarking, and eQuest simulation. It identifies space heating and electricity as dominant energy and emission drivers, and shows that a full retrofit package can achieve approximately 25% emissions reduction (over 1,100 tCO₂e annually). The study emphasizes separating results from interpretation to strengthen decision-making for prioritising decarbonisation strategies in existing multi-residential buildings.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では、改正建築物省エネ法や2030年目標に向け、既存集合住宅の省エネ・脱炭素化が急務である。本論文の監査手法やレトロフィット効果の定量化は、日本のマンション・アパートの改修計画や、SSBJに基づくGHG排出量算定・削減目標設定に応用可能な知見を提供する。
In the global GX context
Globally, building operations account for a significant share of emissions, and this paper provides a replicable audit framework that aligns with TCFD/ISSB disclosure requirements for real estate portfolios. The quantified retrofit impact (25% reduction) offers evidence for transition finance and net-zero pathways in the building sector.
👥 読者別の含意
🔬研究者:The systematic audit methodology combining multiple data sources and simulation can be adapted or refined for other building types and climates.
🏢実務担当者:The retrofit package and its quantified impact offer concrete benchmarks for property managers and owners planning decarbonisation investments.
🏛政策担当者:The study provides empirical evidence on the effectiveness of deep retrofits, supporting the design of building energy codes and subsidy programs.
📄 Abstract（原文）
This research investigates a structured energy audit methodology to support the decarbonisation of multi-residential buildings, with a primary focus on operational energy performance. The objective is to develop and apply a systematic framework that integrates audit levels, detailed data collection, and software-based energy modelling to quantify energy use and greenhouse gas emissions. The methodology combines site inspections, thermographic analysis, benchmarking, and eQuest simulation to evaluate baseline conditions and retrofit scenarios. Results identify space heating and electricity consumption as dominant energy and emissions drivers. Targeted retrofit measures demonstrate substantial potential to reduce energy demand and carbon intensity when expressed in kg CO₂e. Importantly, the correlation analysis does not capture retrofit interactions, system efficiencies, or behavioural adaptations following upgrades, nor the compounding effects of bundled measures. Carbon-counting results show these combined effects to be significant, with the full retrofit package achieving an overall emissions reduction of approximately 25%, equivalent to more than 1,100 t CO₂e annually. Overall, separating results from interpretation strengthens decision-making and confirms the value of operationally focused audits for prioritising decarbonisation strategies in existing multi-residential building stock.
