摘要
为了解决公共建筑碳排放核算类别繁多、结果粗放的难题,通过调研与程式化扎根理论得出影响公共建筑碳排放的关键因素,并依托实地传感测算试验,研究人流量对环境变化的具体作用机理,整合人时变量,构建了适用于公共建筑的动态碳排放核算模型.结果表明:1)编码处理和调研数据的相关性分析结果均显示人流量对公共建筑的能源消耗起到关键作用;2)人流量间接作用于用能系统以及人的自身排放共同组成温室气体的排放增量;3)经验证,研究构建的动态核算模型原始误差为5.36%,修正后误差降至4.807%(小于5%),与实际运行工况有良好的交互性.研究成果完善了已有公共建筑的碳排放核算边界,构建了动态工况下的核算模型,实现了基于动态人流量变化下的公共建筑碳排放定量描述,为绿色建筑评价体系提供了理论依据与模型基础.
Abstract
In order to solve the problem of various types and extensive results of carbon emissions accounting for public facilities,the key factors affecting carbon emissions of public facilities were obtained through investigation and stylized grounded theory.Based on the field sensing measurement test,the specific mechanism of human flow on environmental change was studied,and a dynamic carbon emission accounting model suitable for public facilities was constructed by integrating the variable of human and time.The results show that:1)The correlation analysis between coding processing and survey data shows that human flow plays a key role in the energy consumption of public facilities;2)The incremental greenhouse gas emission is caused by the indirect effect of human flow on energy-using systems and the human emissions;3)It is verified that the original error of the dynamic accounting model is 5.36%,and the error is reduced to 4.807%(less than 5%)after correction,which has good interaction with the actual operating conditions.The research results have improved the carbon emission accounting boundaries of existing medical facilities,constructed the accounting model under dynamic working conditions,realized the quantitative description of carbon emission in public facilities based on dynamic changes in human flow,and provided a theoretical basis and model foundation for the green building evaluation system.
