Capacity, inventory, reserve and utilization by urban district, type of ownership, area development, residential share

Every year, the Office for Urban Development models the structural capacities of all building zones in floor areas on the basis of planning law options and further framework conditions. As part of the modelling, the stock is also estimated in floor space and a structural reserve is calculated by subtracting from the capacity. Assumptions are made specifically for the calculation of population scenarios in order to model the most realistic use of reserves. Note: The model for calculating floor areas for capacity, stock, reserve and uptake is based on assumptions and estimates. The figures should be interpreted with caution in terms of accuracy. The capacity and reserve calculation model (KaReB) has been further developed over the years. Content: Capacity, inventory, reserve and utilization aggregated by urban district, type of ownership, calculated with and without area development as well as by minimum, real and maximum residential share. The values quantify floor areas in square meters. They only include the residential uses, other uses (non-residential) are not taken into account.每年，城市发展办公室（Office for Urban Development）都会基于规划法规方案及其他框架条件，对所有建筑区域的楼面面积结构承载能力开展建模工作。建模过程中，还会对楼面面积存量进行估算，并通过从总承载能力中扣除存量，计算得到结构储备容量。为了最真实地模拟储备容量的使用情况，研究人员针对人口场景的计算设定了特定假设条件。注意：用于计算承载能力、存量、储备容量及使用量的模型基于假设与估算值，相关数据的准确性需谨慎解读。承载能力与储备容量计算模型（KaReB）历经多年迭代优化。 内容涵盖：按城市行政区、产权类型聚合的承载能力、存量、储备容量及使用量，分别考虑有区域开发与无区域开发两种场景，并以最低、实际及最高住宅占比进行测算。所有数值以平方米为单位量化楼面面积，且仅涵盖住宅用途，未纳入非住宅类其他用途。
