Energiekonzept 2050 f\ufcr die Stadt Z\ufcrich - Auf dem Weg zur 2000 Watt tauglichen W\ue4rme-Versorgung mit einem r\ue4umlich differenzierten Geb\ue4udeparkmodell

This project develops a heat demand and supply concept for the City of Zurich within the framework of the 2000 Watt society. Heat and electricity demand and supply were simulated with a building stock model that aggregates buildings that are similar by type, construction period, usage, and location, etc. by using building specific information of an official data set of the buildings and apartments within the city of Zurich. Based on official GIS-Data, the city area was divided into 16 supply zones for which a specific energy carrier mix for the year 2050 was defined. With regard to the regional development strategy (RES) the city area was also divided into 5 demand zones, which differ in monument conservation regulations entailing less stringent measures (e.g. lower specific retrofit rates, demolition rates, heat transfer coefficients). With ambitious, but realistic retrofit measures, efficient use of electricity and tapping available renewable energy potentials to a large extent it is possible to reach the goals of the 2000-Watt-Society within the modeled framework
