Varied housing types draw mixed-income communities; people of all economic strata can live close to work. ICON Clean energy Lighter and cheaper blade- less wind turbines on building rooftops provide supplemen- tary energy. Vertical farming Crops planted vertically become standard, bringing people and food closer together and reduc- ing transport costs and emissions. Cleaner air Green ventilation systems reduce demand on energy- intensive conventional climate-control systems. Public billboards Real-time video displays relay information to the public and update citizens on the city’s energy-saving measures. Drone commuting Remotely programmed drones become large and powerful enough to transport people within the city. Wetland restoration The world has lost one-third of its wetlands since 1970. Future cities preserve and restore all that remain. Dense districts Highly efficient public trans- portation yields clustered businesses that are more accessible to regional talent. Old spaces, new uses Renovation can be greener than new construction. Old transit facilities become multifunctional spaces. Commuter community Transportation centers become the daily hubs of the city, hosting markets, galler- ies, and cultural events. Underground farming Soil-free hydroponic farms grow produce under high- efficiency LED lights, directly beneath homes and offices. Zero water loss All rainfall is captured and used to supply the city’s irrigation systems and drinking water. Enhanced waterways Natural water systems run throughout neighborhoods to manage flooding and provide wildlife habitat. Soaking it up Permeable sponge-city surfaces that let precipitation sink into the water table are mandated in the city. Celebrating diversity Cultural festivals and venues to support them are important elements of increasingly diverse and densely packed cities. Differing heights Not all buildings are high- rises. Sustainable practices can be more effective at three to five stories. Local food, local markets Commercial supermarkets and farmers markets are evenly distributed and rely mostly on local producers. Smarter streets Cities of the future will be largely car free and designed for pedestrians, as Ponteve- dra, Spain, is today. Strategic landscaping Only local plant species are used in a gardening style known as xeriscaping, which requires little or no irrigation. Flexible buildings Modular interiors can be “ hot swapped” for other uses in response to new economic conditions or innovations. Environmental nerve center The city’s environmental monitoring center tracks habitat indicators like air, water, and soil quality. Small business support Collaborative and shared workspaces are abundant and distributed throughout the city. Green structures Natural environments can flourish atop buildings built low to the ground or underground. Bicycle connectivity In today ’s Copenhagen, 40 percent of commuters ride bikes. In this future city, 50 percent of commuters will. Structural design Efficient materials such as stretchable steel accelerate construction time and reduce a building’s carbon footprint. Skyways Buildings connect at upper levels to reduce travel times and street-level congestion. Delivery by rail Automated warehouse and distribution centers also use rapid-transit systems to deliver goods on demand. Transit hubs High-speed rail, buses, light rail, commuter trains, and ride-share options connect in one centralized place. Flood protection Barriers are constructed to block storm surges and create new marine habitats. food production to delivery and disposal. Global standards are established for organic farming and animal treatment; most pro- duce is locally sourced. Sustainability prac- tices are mandated across the life cycle of a product, from FOOD CULTURE In the densely populated and diverse city of the future, historical heritage is preserved and celebrated. Recreation, arts, and entertainment can be shared globally through virtual and augmented reality. Waste becomes a resource to pro- duce energy or alterna- tive material. Landfills WASTE and abandoned indus- trial areas are gradually converted to other pur- poses after soil reme- diation. Wastewater is treated for irrigation or human consumption. Traveling in the city of the future is more affordable, safe, and convenient MOBILITY because of automated technology and high- speed rail. Fewer personal automobiles are on the road and more pedestrian space is available.
