This paper proposes an integrated BIM-based simulation framework for assessing energy demand, photovoltaic potential, and thermal performance in residential buildings. Applied to a UK case study, results show PV generation of 9.7 MWh/year covers 60% of electricity demand, reducing CO2 emissions by 2.2 tCO2 annually. The framework enables realistic multi-domain assessment without geometric simplification, supporting early-stage building design.

📄 Abstract（原文）
<title>Abstract</title> <p>The increasing demand for low-carbon and energy-efficient residential buildings has intensified the need for integrated performance assessment frameworks that can simultaneously evaluate energy consumption, renewable energy potential, and indoor thermal conditions. Conventional building energy studies often rely on isolated simulation approaches, limiting the ability to capture the interdependencies between building systems, solar resources, and occupant comfort. This gap is particularly evident in small-scale residential developments, where practical, simulation-ready workflows remain underdeveloped. This study proposes a BIM-enabled integrated simulation framework for assessing energy demand, photovoltaic (PV) potential, and thermal performance in residential buildings. A detailed multi-zone building model was developed from an as-designed BIM model and implemented in TRNSYS, incorporating construction properties, occupancy schedules, internal heat gains, and local climatic data for Guisborough, United Kingdom. The framework integrates energy modelling, solar irradiation analysis, and HVAC system simulation within a unified workflow. The results demonstrate that the building maintains stable indoor thermal conditions within comfort ranges (20–24.3°C) throughout the year while exhibiting a dominant heating demand of 33.2 MWh and minimal cooling requirements. The integration of a 33-module PV system generates approximately 9.7 MWh annually, covering up to 60% of the building’s electricity demand and achieving a seasonal energy surplus during summer months. The system contributes to an estimated annual reduction of 2.2 tCO₂ emissions. This study is original in using a fully detailed BIM-derived model without geometric simplification to enable realistic, reproducible multi-domain assessment. Unlike conventional methods, it integrates energy, solar, and thermal analysis within a practical workflow for early-stage design and small-scale residential buildings.</p>
