Abstract :
[en] Greenhouse gas emissions from building operations contribute significantly to global emissions. Although net zero energy buildings have been developed to reduce operational energy use, net zero emission operations are not always achieved. Plug-in battery energy storage systems enable building operations using renewable energy sources at night, when photovoltaic systems are intermittent. The application of 24/7 carbon-free energy metrics in the context of plug-in battery energy storage systems in timber residential buildings in the study advances the existing knowledge base. The building performance was assessed using high-resolution dynamic grid emission factors from utility grids across the Group of Seven Countries. Study results indicate that plug-in battery energy storage systems increase electricity use intensity due to energy losses during charging and discharging cycles. However, operational emission intensity is highly dependent on the dynamic grid emission factors. Locations with higher daytime carbon intensity, such as Tokyo, showed an increase, whereas locations with higher nighttime carbon intensity, such as Berlin, showed a decrease. Diurnal analysis revealed increases in daytime electricity use intensity and operational emission intensity during charging cycles, while discharging cycles led to decreases in these metrics during nighttime. Furthermore, the 24/7 carbon-free energy analysis demonstrated improvements ranging from 1.8% in Paris to 32.3% in Tokyo with plug-in battery energy storage systems, highlighting the strong influence of low-carbon electricity sources in the utility grid. The research findings emphasized the importance of integrating plug-in battery energy storage systems into net zero energy residential buildings to enhance low-carbon electricity operations and self-consumption.
