This study evaluates the environmental, economic, and social performance of EV charging strategies in solar-integrated net-zero energy buildings using a life cycle sustainability assessment framework. Analyzing a Canadian case, it finds that bi-directional smart charging offers the greatest sustainability benefits, reducing annual grid electricity use by up to 70% and lowering life cycle environmental impacts by 2.4-21.2%, costs by 2.3%, and social impacts by 1.2-1.8%. State of charge at arrival and battery replacement thresholds are identified as key drivers.

📄 Abstract（原文）
ABSTRACT Transitioning to electric vehicles (EVs) and integrating them with renewable energy systems is crucial for reducing transportation sector emissions. Solar-integrated near or net-zero energy buildings and smart charging technologies offer a promising pathway, yet concerns about battery degradation, increased costs, and uncertain long-term sustainability continue to limit widespread adoption. This study evaluates the environmental, economic, and social performance of EV charging strategies using a parametric life cycle sustainability assessment framework that integrates life cycle assessment, life cycle cost analysis, and social life cycle assessment. The analysis compares three charging approaches: regular, uni-directional smart, and bi-directional smart charging, while systematically varying five key parameters: battery replacement thresholds, state of charge (SOC) at arrival, building energy demand, solar generation levels, and charging rate limits. Results from the Canadian case study demonstrate that bi-directional smart charging provides the greatest sustainability benefits, reducing annual grid electricity use by up to 70% and lowering life cycle environmental impacts by 2.4-21.2%, costs by 2.3%, and social impacts by 1.2-1.8%, compared with regular charging. SOC at arrival and battery replacement thresholds were identified as the dominant drivers of sustainability outcomes. These findings highlight the importance of evaluating the long-term sustainability of emerging building-transportation energy systems and provide insights for achieving net-zero community and EV integration goals.
