摘要：
基于建筑全生命周期理念,建立了融合主动与被动设计策略的寒冷地区办公建筑低碳化优化模型,旨在探索建筑生命周期内的能源节省、经济效益和环境效益的协同最优解。通过对隐含项和运行项的深入分析,揭示了建筑本体与实际运行之间的内在联系,并指出了未来优化的潜在方向。在寒冷地区,与基准建筑相比,最优方案虽增加了11.12%的经济投入,但实现了59.47%的建筑能耗降低和33.95%的全生命周期碳排放减少,充分展示了建筑全生命周期节能降碳设计的成效。其中,主动设计中的光伏发电技术是实现建筑向低碳节能化转型的关键手段。
Abstract：
Based on the concept of building life cycle, a decarbonization optimization model for office buildings in cold zone, combining active and passive design strategies, is established to explore the synergistic optimization solution of energy savings, economic, and environmental benefits during the building life cycle. Through in-depth analysis of embodied and operational aspects, the intrinsic connection between the building’s design and its actual operation is revealed, and potential directions for future optimization are highlighted. Compared to the baseline building in cold zone, the optimal solution reduces energy consumption by 59.47% and whole-life carbon emissions by 33.95% despite a modest 11.12% increase in the life cycle cost. This underscores the profound effectiveness of energy-saving and low-carbon design strategies throughout the building life cycle. Moreover, the proactive design of photovoltaic power generation technology is identified as a crucial strategy for transforming buildings towards energy-saving and low-carbon development.
