Energy Supply Concept 2050 for the City of Zurich
On behalf of the City of Zurich, we developed a concept for the energy supply of 2050.
The scenario calculations showed that for the city of Zurich a heat supply is possible that is compatible with the requirements of the 2000-watt society. With the Building Park Model (GPM) the building-related heat and power consumption for heating, hot water, cooling, air renewal, lighting and other power applications was quantified in two main scenarios. The scenarios differ in the assumptions on the efficiency development of the buildings and in the energy mix used for heating and electricity.
The results show that energy demand and greenhouse gas emissions can be significantly reduced between 2005 and 2050 despite an increase in heated and air-conditioned areas (energy reference areas).
In 2015, the scenario calculations were updated to take into account the latest data from the Office for Urban Development regarding population development and land potential as well as interim energy and climate policy developments. These results formed the basis for the revision of the municipal energy planning of the City of Zurich.

Low-temperature district heating networks. The basis for modernizing the heat sector.
Renewable energies and waste heat sources are to replace the coal and natural gas sources that have dominated Polish district heating networks up to now.
First and foremost, this requires a reduction of the system temperature. The study shows the technical, regulatory and organisational measures required to achieve this
and determines the overall potential for decarbonising district heating in Poland.
