Research On Carbon Assessment Of The Built Environment In OCT Community, Shenzhen

Along of the world’s population growth and economic development, resourceconsumption and environmental infulence of urban construction and operationimpact people’s living environment more and more seriously. In response to theenergy crisis and climate change issue, countries all over the world have beenthrough their own efforts to pursue low-carbon attempt.As main place for people towork,live and enjoy entertainment,urban community has been playing a importantpart in practise respending to climate change being both the basic platform forsusstainable development and space carrier to achieve low carbon economy.And it’sof great importance for the transformation of urban development paradigm as well.Current carbon assessment exsists mostly in form of excel data,which is uncapableof revealing the impacts urban space elements produce on carbon emissions.Thecarbon assessment model is far from appropriate when it comes to the issue ofguiding low carbon urban planning.This subject followed the technical route of "Why it it—What it is—What todo—How to do". Firstly, by connecting the content, methods and tools oflow-carbon urban construction,it suggested the low carbon planning trend ofexplannig the relationship of urban/community scale built environmentcharacteristics and energy demand and carbon emissions, and that low carbonplanning should make environmental decision-making compatible with carbonemissions impact, such as land use, urban form and architectural forms, etc.On thistheoretical basis,“cabon assessment of built environment” was explained fromaspects on concept definition,object system,the target composition and basiccharacteristics, which as the theoretical basis of modeling addressed the questionof“what it is”. Secondly, the assessment model framework of built environment wasbuilt up through computing formula and spatial resolution according to the carboncycle elements and community functional analysis, to solve the question of “what todo”. Again, the OCT community carbon cycle was modoled through metabolicapproach to quantify the storage, vertical flow and level flow of carbon incommunity. Model input data (land cover, population, type of construction,planting) derived from a combination of spatial and non-spatial data. Model outputwas represented by carbon flow results and its spatial resolution of the wholecommunity and independent sectors of buildings, residents travel, residents lifies,soils and plants to analysis the carbon emissions spatial distribution charisristics ofOCT cummonity. And the impacts of carbon emissions was discussed from builtenvironment features and planning indicators to solve the question of “how to do”. The construction methods and applications of carbon assessment model ofcommunity built environment based on metabolic theory is core results of thisobject.
