Research On Carbon Reduction Design Of Industrial Parks Based On Multi-objective Optimizatio

In order to cope with the environmental crisis of climate warming and achieve sustainable development of society,it has become a consensus among countries to reduce greenhouse gas emissions represented by carbon dioxide.As China’s urbanization continues to deepen and the economic level continues to improve,the carbon emissions from the construction industry and its share in the total carbon emissions of the country continue to increase,causing a great impact on the environment and the sustainable development of society.On the issue of carbon reduction in the construction industry,industrial parks are large in volume,diverse in function,complex in industrial structure and diverse in emission paths,and it is of universal significance to study carbon reduction in parks.In order to cover building heating,an important carbon emission constituent of the construction industry,the study selects industrial parks in cold regions as the research object,in order to provide theoretical support for the research of carbon reduction in industrial parks from the design perspective.Firstly,a literature mapping study is adopted to compare,develop and frontier analyze 3498 Chinese and foreign literature in the field of low carbon industrial parks at home and abroad,and it is found that there is a gap of multi-domain synergy as well as simulation optimization in domestic industrial park low carbon research.Secondly,combining with the carbon emission and outdoor thermal comfort evaluation system combing,we summarize the design influence elements that affect the carbon emission and outdoor thermal comfort of the park,establish a multi-objective optimization model for industrial parks based on the Carbon Accounting Standard(CAS)evaluation system and the outdoor thermal comfort index model BOCI,and use multi-intelligence simulation to realize the The layout of the park is optimized using multi-intelligence simulation.Subsequently,we conducted field research on industrial parks and analyzed the carbon reduction paths from carbon emissions,carbon sinks,energy-saving technologies and other dimensions,and verified the problem of lagging park design in the carbon reduction construction of industrial parks in the literature review.The third chapter of the article combines IPCC and literature review to determine the composition of carbon emission accounting in industrial parks in cold regions,accounting boundary and the evaluation criteria of this study for outdoor thermal comfort.Then,it is confirmed that this optimization study is divided into two parts: firstly,a numerical model based on building multi-intelligence constitutes the impact model of carbon emission and outdoor thermal comfort in the park;secondly,the specific impact of various elements on carbon emission in the industrial park is quantified according to the input.Finally,the design of the research program is carried out based on the above analysis.The first step in the construction of the multi-objective optimization model for industrial parks is to extract the planning topology and building modulus for 12 green industrial parks: the layout of industrial parks is divided into two types of planning and design prototypes: centralized and zoned,and the building modulus of industrial parks is divided into three types of production buildings,residential buildings and office buildings,and the intelligent body is constructed in turn to complete the intelligent body translation of park planning.Then,according to the influence model of carbon emission and outdoor thermal comfort in the industrial park,the carbon emission constraint and outdoor thermal comfort constraint are constructed on the basis of the layout of the intelligent body in the park,and the multi-objective optimization model is completed.Based on this optimization model,we conducted arithmetic simulation to verify the optimization between the annual carbon emission of the park and the outdoor thermal comfort of the park.And by adjusting the input variables,the specific numerical impact of each carbon reduction element on the carbon emission of the park is quantified.Finally,the optimization results are organized and visualized,and the optimization suggestions for the design of carbon reduction in industrial parks in cold regions are analyzed.The article innovates in the following five directions: First,through literature mapping research,it explores the differences between domestic and international low-carbon park research and research development,and points out the directions that need to be explored in domestic low-carbon industrial park research: multi-domain synergy(thermal comfort,sensory,building form),life-cycle assessment,and quantitative simulation.Secondly,based on literature study,the main influencing elements of design impact are extracted from the macroscopic multidisciplinary carbon emission evaluation system: transportation energy,building energy consumption,clean energy,and forestry carbon sink.And based on the calculation system to establish the link between carbon emission and design.Third is the extraction of park planning layout and building modulus.By analyzing park layout,summarizing zoning characteristics,combining with field research,extracting building modulus,and constructing simulated park functional zoning based on building intelligences,the intelligences planning model of two types of industrial parks is constructed.Fourthly,based on cold regions,the optimization model is combined to quantify the impact of each design influence element on carbon emission and propose the optimization strategy for cold regions that simultaneously meets carbon reduction and outdoor thermal comfort.Fifth,the low-carbon park layout is automatically constructed by adjusting the inputs,which can provide designers with a reference for park planning.
