体现与运行环境指标通常是孤立研究的。本文对英国伦敦市中心一栋规划中的大中型办公楼的节能措施进行了从摇篮到坟墓的生命周期分析,该办公楼总建筑面积为 15,590 平方米,建筑寿命为 60 年。原始设计符合英国建筑法规 L 部分,与目标排放率相比,运营碳排放量减少了 40%。 LCA 解决方案侧重于结构、围护结构和操作系统。具体节能策略包括精益设计原则的应用和低碳材料的整合。运营节能技术包括采用织物优先的方法、自适应热条件和可持续建筑系统。与原始设计相比,这些优化策略累计最多可节省生命周期碳排放和能源 16% 和 13%。隐含策略在隐含碳和能源方面分别节省了 32% 和 9%,而运营策略在这两个指标上都将原始消耗减少了 14%。在 60 年的建筑生命周期中,运行能源比隐含能源高 10 倍,而运行碳比隐含碳高 8 倍。研究结果强调了 LCA 对于早期建筑设计决策的重要性。
Embodied versus operational environmental indicators are often studied in isolation. This paper presents a cradle-to-grave Life Cycle Analysis of energy conservation measures for a planned large, medium-rise office building in central London, UK with Gross Floor Area of 15,590 m2and a 60-year building lifetime. The original design complied with the UK Building Regulations Part L, achieving 40% operational carbon emission savings compared to Target Emissions Rate. The LCA solutions focused on structure, envelope, and operational systems. Embodied energy saving strategies encompassed the application of lean design principles and integration of low carbon materials. Operational energy saving techniques included the adoption of a fabric-first approach, adaptive thermal conditions and sustainable building systems. Cumulatively, these optimization strategies achieved a maximum of 16% and 13% savings on life cycle carbon and energy, respectively, compared to the original design. Embodied strategies saved 32% and 9% on embodied carbon and energy, respectively, while operational strategies reduced the original consumption by 14% on both indicators. Over a 60-year building lifetime, operational energy was 10 times higher than embodied energy, while operational carbon was 8 times higher than embodied carbon. The study findings have highlighted the significance of LCA for early stage building design decisions.
