Digital Twin for Positive Energy Districts

A new, diverse urban quarter is being created at "Kempelenpark" in Vienna. Around 1,100 rental flats will be created in what has been a purely commercial location up to now. Two thirds of these will be built on a non-profit basis and one third will be privately financed. This will enable high-quality and at the same time affordable living. In combination with a wide range of commercial areas, local supply and the construction of an all-day primary school and a kindergarten, a balanced mix of living space will be created.

A large public park forms the heart of the urban development planning. Together with the adjoining green spaces, the area will contribute to a climatically pleasant living environment in the future. Sustainable mobility and the networking of inner-city routes (Sonnwendviertel and Böhmischer Prater) make the new urban quarter a promising project for the entire district.

The district consists of mainly residential buildings constructed in the 1950s and a school for 500 school kids (pre-school and 1st - 9th grade, 6 – 16 years) constructed in 1957. The residential buildings have three floors and are lamellar buildings group around larger green areas. Most of the apartments have 1 bedroom (2 rooms and a kitchen, 385 apartments), the remaining apartments are either 1 room (58 apartments) or 3 rooms (83 apartments) with a kitchen, and only one apartment has 4 rooms and a kitchen. The residential buildings are owned and managed by the municipal housing company Poseidon. Poseidon also owns 295 parking lots in the area and manages an existing boiler plant. The school is owned and managed by the municipal company Lokalförvaltningen which is responsible for all schools in Gothenburg.
The PED-Living Lab includes both retrofitting of the existing buildings and densification by adding 3 buildings (A-C) on properties owned by Poseidon (Building A and B) and the City of Gothenburg (building C). For construction of building C an existing garage building with 10 parking lots and a recycling room will be demolished.

The Camili District is a new settlement established after the 1999 earthquake. Huge green parks, hospitals, new residential buildings, schools, shopping malls, mosques, university buildings, bike valley and huge bike paths, highways and governor’s office are located here. In the scope of this project, it’s planned to figure out a positive energy district by implementing Digital Twin tools.

Total area of the district is about 4.380.000 m2, there are 853 buildings which are mostly residential uses. In Fig. 7, digital twin approach is presented. Electricity, gas and water consumptions data will be gathered from utilities (co-operation partners) and the data will be processed according the digital twin approach. Representative buildings were identified as below. These buildings will be monitored and monitored data will be utilized for the district-level scenario developments.

Digital Twin platform delivers energy and environmental assessments, integrated with building and district-level digital twins. In addition, it monitors indoor air conditions of buildings for occupant wellbeing. In the scope of this project, Digital Twin Platform will be integrated into selected representative buildings of Camili District.
