ABSTRACT This article offers a conceptual understanding and easily applicable guidelines for sustainable urban infrastructure design by focusing on the demand for and supply of the services provided by seven urban infrastructure systems. For more than 10,000 years, cities have evolved continuously, often shaped by the challenges they had to face. Similarly, we can imagine that cities will have to evolve again in the future to address their current challenges. Specifically, urban infrastructure will need to adapt and use less energy and fewer resources while becoming more resilient. In this article, starting with a definition of sustainability, two urban infrastructure sustainability principles (SP) are introduced: (i) controlling the demand and (ii) increasing the supply within reason, which are then applied to seven urban infrastructure systems: water, electricity, district heating and cooling and natural gas, telecommunications, transport, solid waste, and buildings. From these principles, a four-step urban infrastructure design (UID) process is compiled that can be applied to any infrastructure project: (i) controlling the demand to reduce the need for new infrastructure, (ii) integrating a needed service within the current infrastructure, (iii) making new infrastructure multifunctional to provide for other infrastructure systems, and (iv) designing for specific interdependencies and decentralizing infrastructure if possible. Overall, by first recognizing that urban infrastructure systems are inherently integrated and interdependent, this article offers several strategies and guidelines to help design sustainable urban infrastructure systems. Keywords: sustainability; infrastructure; energy generation; transportation; water
DISCUSSION POINTS • H ow can looking at the demand for and supply of infrastructure services help redefine how urban infrastructure is planned, designed, and operated? • T wo pragmatic principles for sustainable urban infrastructure system design. • D esign strategies for seven urban infrastructure systems: water, electricity, district heating and cooling and natural gas, telecommunications, transport, solid waste, and buildings. • A four-step process to help design sustainable and resilient infrastructure systems.
Introduction In Democracy in the Politics, Aristotle wrote: “The city-state comes into being for the sake of living, but it exists for the sake of living well.” For more than 10,000 years, humans have
settled together in cities because as a society we tend to live “better” than individually. Despite the countless utopias that depict small and agrarian settlements, and despite the cycles of urban growth and decline, cities keep getting larger and more comp
