SU STAIN ABL E CI TI ES A N D BU IL DI N GS Urbanization, resource scarcity and climate change represent big challenges for cities in the next years. The world’s cities account for two thirds of energy consumption, 60 percent of total water consumption and 70 percent of emitted greenhouse gases production. On top of that, cities continue to grow. More than 50 percent of the world’s population lives already today in metropolitan areas. By 2050 up to 70 percent of the world’s population will live in metropolitan areas.The fight against climate change and environmental pollution is therefore decided in cities. The sustainable development of cities is therefore the most important challenge in the future. Essential requirements for sustainable cities are sustainable buildings. Currently buildings are responsible for more than 40 percent of the global energy consumption and 21 percent of the world’s greenhouse emissions. In order to provide the sustainability of buildings, boundary transcending solutions are necessary, which consider Building, Mobility, Infrastructure and Energy Generation equally. KNX city demonstrates how these solutions can be integrated in sustainable cities and how those can interact with the building. KN X, A SYSTEM S APPR O ACH I N SU STAI NABL E CI TI E S Building What does the building of the future look like? The building of the future is energy-efficient and communicates with its surroundings (smart grid). KNX already offers solutions today for the intelligent interaction between lighting, shading, security systems, HVAC, monitoring, remote control, measurement, audio/video and domestic appliances in buildings. This topic area will even be extended in the future because of the many new challenges that lie ahead. Mobility How will we get from Point A to Point B in the future? Of course, with vehicles (electric vehicles) and means of transport, whose energy will be supplied exclusively from renewable energy sources. KNX already offers solutions today that allow for excess energy, such as that generated by photovoltaic systems or small wind-powered generators of buildings, to be put to use for charging electric vehicles fully with renewable energy. Infrastructure How will energy management for entire urban districts or townships be managed in the future? Of course, by a solution that spans over multiple buildings. KNX already offers solutions today for distributed properties by linking them up via communication technology and IP/Internet as if they were one single building. Energy Generation How will we generate the energy we need in the future? Of course, by using predominantly renewable sources, e.g. sun and wind. KNX already offers solutions today that make it possible to counter the problem of fluctuating power generation in photovoltaic systems and wind-powered generators. This is done through load management, thereby increasing the proportion of renewable energy used. • General functionality of KNX • Procurement of KNX solutions (e. g.
