既有建筑围护结构低碳改造设计策略研究 ——以北京市某园区提质改造项目为例
Research on low-carbon renovation design strategies for existing building envelopes—Taking an upgrading and renovation project of a park in Beijing as an example
摘要：
我国量大面广的既有建筑大多采用传统的建筑材料和建造技术,保温隔热性能差,能源利用效率低,导致建筑能耗居高不下。因此亟需通过具有针对性的改造措施,以降低碳排放量为目标来提升既有建筑的整体品质。本文通过对实际项目不同位置的外围护结构改造策略进行能耗模拟分析,寻求最优的既有建筑低碳改造策略,助力实现建筑领域碳达峰、碳中和目标。
Abstract：
Most of the existing buildings with large quantities and wide coverage use traditional building materials and construction technologies, which have poor thermal insulation performance and low energy utilization efficiency, resulting in high building energy consumption. Therefore, targeted renovation measures are urgently needed to improve the overall quality of existing buildings with the goal of reducing carbon emissions. This paper conducts the energy consumption simulation analysis on the renovation strategies of external envelopes in different locations of actual projects, in order to seek the optimal low-carbon renovation strategy for existing buildings and contribute to achieving the goals of carbon peaking and carbon neutrality in the construction industry.
