夏热冬冷地区既有办公建筑近零能耗改造策略——以苏州市某项目为例

Near-zero Energy Retrofit Strategy for Existing Office Buildings in Hot Summer and Cold Winter Areas-An Example of a Project in Suzhou

建筑领域的节能减碳工作对我国“双碳”目标的实现至关重要,而发展超低能耗建筑、近零能耗建筑是实现该目标的重要举措。相比新建建筑,规模庞大的既有建筑改造具备更大的节能潜力,控制既有建筑的运行能耗将成为节能工作的重点。以苏州市某既有办公建筑的近零能耗改造项目为案例,介绍了该项目的改造目标和技术路径,分类分析了该项目实现近零能耗目标所采用的被动式、主动式和可再生能源应用技术策略,为夏热冬冷地区近零能耗工程推广和技术应用实践提供有意义的参考。

Energy saving and carbon reduction in the building sector is crucial to the realisation of China's"double-carbon"goal,and the development of ultra-low-energy buildings and near-zero-energy buildings is an important step towards achieving this goal.Compared with new buildings,large-scale renovation of existing buildings has greater energy-saving potential,and controlling the operational energy consumption of existing buildings will become the focus of energy-saving work.Taking the near-zero energy retrofit project of an existing office building in Suzhou as a case study,we introduce the retrofit goals and technology paths of the project,and classify and analyse the passive,active and renewable energy application technology strategies adopted in the project to achieve the goal of near-zero energy consumption,so as to provide meaningful references for the promotion of near-zero energy consumption projects and the practice of technology application in hot summer and cold winter areas.
