ABSTRACT

Considering the large spatial scale of urban development in metropolitan areas, data quality and resolution are very important in determining accurate material stock figures. There is currently a limited but growing number of studies that employ bottom-up accounting based on high resolution spatial data rather than analysis of aggregated city-level data as was employed in relatively older studies. This study contributes to this literature by assessing Net Additions to Stock (NAS) in Eryaman, Ankara, Turkey using GIS software NETCAD. It was determined that NAS on a per capita basis for the early and mature stages of urban development correspond to 1,800 and 240 ton/capita, respectively. These figures of material stock are greater than that of many other cities owing to high Material Intensity Coefficients (MICs) of reinforced concrete and masonry structures prevalent in the study area. When energy demand for construction materials was considered, it was determined that the material stock has a total embodied energy of 21.2 TJ in 2015. The findings of the study, in line with previous findings in the literature for other urban areas, point to the need for focusing on material selection as functional elements and intensified eco-efficiency efforts for sustainable urban development.Not Started Completed Rejected.

摘要

考虑到大都市地区城市发展的大空间尺度，数据质量和分辨率对于确定准确的材料库存数字非常重要。目前有数量有限但越来越多的研究采用基于高分辨率空间数据的自下而上核算，而不是像在相对较早的研究中采用的对聚合城市级数据进行分析。本研究通过使用 GIS 软件 NETCAD 评估土耳其安卡拉 Eryaman 的库存净增加量 (NAS)，为该文献做出了贡献。确定城市发展早期和成熟阶段的人均 NAS 分别对应于 1,800 和 240 吨/人。由于研究区域普遍存在钢筋混凝土和砖石结构的高材料强度系数 (MIC)，这些材料库存数字高于许多其他城市。在考虑建筑材料的能源需求时，确定 2015 年材料库存的总隐含能量为 21.2 TJ。该研究结果与之前其他城市地区文献中的发现一致，表明需要注重材料选择作为功能元素并加强生态效率工作以促进可持续城市发展。未开始 已完成 拒绝。
