Powering the energy transition at the district level_Cities4PEDs_AWB_final

Central district heating for
energy sustainability
At the time of the district’s development
planning, there was no explicit mandate to become an energy
district. Instead, the development goal focused on liveability.
The 2014 Smart City Vienna framework strategy provided a
strong impulse for energy efficiency. Today, aspern Seestadt is
a gas-free district. The connection and expansion of the city’s
district heating system laid the groundwork for the exclusive
use of renewable energy. In addition, this newly built environment
offered the opportunity to test decentralized renewable
energy technologies such as heat pumps as well as thermal and
electrical storage. A monitoring model optimizes consumption
patterns and the exchange of data between buildings.
4. In 2014 the City of Vienna
committed to reduce greenhouse
gas emissions by 50% by 2030
and by 85% by 2050 compared to
the base year 2005, as stated in
its Smart City Wien Framework
Strategy with concrete actions to
achieve these goals. Today, the
new Smart Climate City Strategy
sets an even higher target: to
become carbon-neutral by 2040.
In both these documents, aspern
Seestadt is mentioned as a test bed
for Smart City research where the
City of Vienna and Siemens AG are
implementing sustainable solutions
based on real buildings.
