摘要

近年来,传染病的全球威胁促使各国加大建设高水平生物安全实验室的力度。然而,生物安全实验室在运行过程中的高能耗导致其利用率较低。本研究以西南地区生物安全4级(BSL-4)实验室为研究对象,在保证安全的前提下进行能源优化。研究发现,BSL-4级实验室的供暖、通风和空调(HVAC)系统消耗的能源是标准办公室的4.3倍。通过减少换气次数和对废气进行热回收,可以分别节省36%和35%的能源。此外,开发了完整的生命周期评估(LCA)模型,发现运营阶段对环境的影响最高,为48%。因此,建议执行高-低交互策略,每年节省25% - 28%的能源,减少24-27吨的碳排放;优化可再生能源后,BSL-4实验室的能源回收期和温室气体回收期分别为9.2年和6.1年。该研究的生命周期评估模型和推荐的节能方案有助于BSL高效的能源设计和运行。

Energy efficiency analysis and life cycle assessment of a biosafety level 4 laboratory
In recent years, the global threat of infectious diseases has prompted countries to increase the construction of high-level biosafety laboratories (BSLs). However, the high energy consumption in the operation of biosafety laboratories leads to their low utilization rate. In this study, a biosafety level 4 (BSL-4) laboratory in Southwest China was used for energy optimization while ensuring safety. It was found that the heating, ventilation, and air conditioning (HVAC) system in a BSL-4 laboratory consumes 4.3 times more energy than in a standard office. Energy savings of 36 % and 35 % could be achieved by reducing the number of air changes and performing heat recovery of exhaust gases, respectively. In addition, a complete Life Cycle Assessment (LCA) model was developed and it was found that the operational stage had the highest environmental impact of 48 %. As a result, it was proposed to perform a high-low interaction strategy that saves 25 %–28 % of energy and reduces carbon emissions by 24–27 tons per year; after optimizing renewable energy sources, the energy payback time and greenhouse gas payback time of the BSL-4 laboratory are 9.2 and 6.1 years, respectively. The study’s life cycle assessment modeling and recommended energy savings scenarios contribute to efficient energy design and operation at BSL.
