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.

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.
