城市设计和规划越来越倾向于增加密度，许多人认为这是实现社会经济和环境可持续性的一种方式。从建筑层面到区域层面的密度定量测量对实践者来说是一个挑战。本文展示了一种新的测量方法，空间比率，用于测量和绘制伦敦建筑和地区的密度潜力。空间比率描述现有密度与允许密度的比率。它是一个多变量的工具，可以潜在地纳入一系列建筑，人员或感知密度的措施。空间比率可以用来测试多种密度测量和场景。作为本研究的一部分，还说明了一种可视化密度势的工具，即“空间比率图”。利用建筑密度的三维数据和几个向上的密度场景，在伦敦Balham和Kensington的案例研究区域测量和绘制了Space Ratio。虽然空间比率和空间比率图取决于高质量的数据，但本研究认为它们可以帮助可持续密度的设计和情景规划。
Urban design and planning are increasingly geared toward increasing density, viewed by many as a way of achieving socio-economic and environmental sustainability. The quantitative measurement of density from the building-level to the area-level presents a challenge to practitioners. This paper demonstrates a new measure, Space Ratio, for the purposes of measuring and mapping the density potential of buildings and areas in London. Space Ratio describes the ratio of the existing density to the permissible density. It is a multi-variable tool that can potentially incorporate a range of measures of building, people or perceived density. Space Ratio can be utilised to test multiple density measures and scenarios. A tool for visualising density potentials, the ‘Space Ratio Chart’, has also been illustrated as part of this study. Drawing on three-dimensional data on building density and several upward density scenarios, Space Ratio has been measured and mapped in the London case study areas of Balham and Kensington. Although Space Ratio and the Space Ratio Chart are contingent on high-quality data, this study argues that they could aide the design and scenario planning of sustainable densification.
