摘　　要：通过在海口一现有建筑上建立屋顶现代温室模型并模拟计算,耦合植物、能源、水对其全生命周期给主体建筑碳排放带来的影响进行定量研究.结果表明:设计使用年限为20 a,面积为840 m^(2)的屋顶现代温室在其建材生产及运输、建造及拆除阶段产生的碳排放量为80 t,运行期间可减少主体建筑碳排放量277.02 t,其全生命周期可减少主体建筑碳排放量199.03 t,即其减碳效益为237 kg∙m^(-2).由此可知,合理建设屋顶温室可成为减少建筑碳排放的措施之一,助力实现双碳目标.In the report,based on one existing buildings in Haikou,rooftop modern Greenhouse model was con-structed,and the simulation calculation were performed,the effects of plants,energy,and water on the carbon emissions of the main building during its life cycle were quantitatively analyzed.The results showed that the Rooftop modern greenhouse with a designed service life of 20 years and an area of 840 m^(2) generates 80 t of car-bon emissions during the production,transportation,construction,and demolition stages of building materials.During operation,the main building's carbon emissions can be reduced by 277.02 t,and its full life cycle can reduce the main building's carbon emissions by 199.03 t,which means its carbon reduction efficiency is 237 kg∙m^(-2).So,the reasonable construction of rooftop greenhouses can become one of the measures to reduce building carbon emissions and help achieve the dual carbon goals.
