基于BIM的绿色建筑排烟系统碳排放优化设计

Carbon Emission Optimization Design for Smoke Exhaust System of Green Building Based on BIM

传统建筑排烟系统在控制碳排放时,存在效率低、控制效果差的问题,因此,在传统排烟系统的基础上,利用BIM技术对建筑排烟系统碳排放进行优化设计。分别从硬件和软件两方面进行优化,系统硬件优化包括排烟管道、管井、排烟机等设备的优化,以并列的方式放置排烟管,设置排风防火阀;系统软件优化则是通过碳排放污染物、烟量和报警程序的设计来实现。为检测系统工作效果,设定对比实验,结果表明:设计的建筑排烟系统能在短时间内实现碳排放控制,当发现异常后会迅速报警,具有较强的实际工作能力。

The traditional smoke exhaust system of buildings has the problems of low efficiency and poor control effect when controlling carbon emissions.Therefore,on the basis of the traditional smoke exhaust system,BIM technology is used to optimize the carbon emission of the traditional smoke exhaust system of buildings.The optimization is carried out from two aspects of hardware and software.The optimization of system hardware includes the optimization of equipment such as smoke exhaust pipes,pipe wells,and smoke exhaust machines.The smoke exhaust pipes are placed in parallel and the exhaust fire dampers are set.The optimization of system software includes the design for carbon emission pollutants,smoke volume and alarm program is realized.In order to detect the working effect of the system,a comparative experiment is set up.The results show that the designed smoke exhaust system of buildings can achieve carbon emission control in a short time,and will quickly alarm when an abnormality is found,which has strong practical working ability.
