Smart cities combine data, especially real-time data, with digital technologies. Behavioural patterns are recognized. Because data can change human behavior. New technologies transmit information about available parking spaces and thus reduce traffic volumes. The public transport network is dense, high-speed and digitally networked. Roads are also intelligently networked, lighting is only active when there is effective traffic, sensors measure traffic volume and not only measure current air pollution, but also predict it. Energy production and consumption are coordinated Translated with www.DeepL.com/Translator (free version)

In the future, more people will share the same area. A city is sustainable when it balances density and access to nature. Another factor is the use of resources. Water consumption and the protection of natural areas must be under control. Water is therefore collected directly on roofs. Sustainable cities have recycling systems that ensure an efficient flow of materials.

Sustainable real estate makes cities green. There are new solutions along the entire value chain: it starts with the building materials. Green Cement, for example, causes fewer emissions and requires less material input. Another variant follows the cradle-to-cradle principle: properties are planned from the outset so that they can be efficiently demolished. Other areas are: Intelligent measuring systems, energy-efficient buildings, passive design (daylight, green facades, natural ventilation etc.).
