CI-NERGY: sustainable urban energy planning in focus <<

The EU project CI NERGY explored sustainable urban energy concepts. As part of CI-NERGY developing innovative planning tools eleven PhD students and three postdocs was promoted worldwide in the past three years. In one of AIT organized final event on February 24 at the TU Vienna the young researchers now presented the results of their work.

At the same time the event professional public provided the opportunity to learn about the latest findings and discuss research needs for the future.

Smarter Together and CI-NERGY

Stefan Geier (MA 20, Vieanna Energy Planning) presented the Viennese way of developing an inclusive energy planning. The related activities include the participation in EU research projects Urban Learning ( , focus planning and management processes) and Smarter Together . As part of Smarter Together the MA20 drew first thematic maps to represent energy-relevant data of the project area in Simmering. A summary of the first results was presented to the audience.
These results will be further developed and linked with findings from other projects such as CI-NERGY. This new planning and decision bases are created to later roll out model citywide. Subsequently, these data will be integrated into a new data platform that also within the project Smarter Together is designed for the whole of Vienna.

Interdisciplinary Education

The aim of the project CI NERGY under the Marie Sklodowska Curie program "Initial Training Networks" the European Commission is the training of young scientists in highly interdisciplinary research field of Smart Cities. "The training network includes leading universities, research centers and industrial enterprises, for the young scientists to combine academic excellence with entrepreneurial innovation capability," said the chief scientist of the project, Ursula Eicker from Stuttgart University of Applied Sciences.

A central role in the education network plays the AIT, which gave a PhD and a postdoc opportunity to research in this promising field at the Center for Energy. In addition, the City of Vienna as a result of its ambitious energy policy next Geneva model city selected for the implementation of individual approaches.
The focus of the work for the Project CI-ERGY is developing software tools to provide planners and city governments economic and environmental decision support for the energy-efficient restructuring of cities. The subjects covered include inter alia integrated energy planning, simulation of energy flows, interactions between buildings and supply networks, as well as 3D city modeling.

City models in 3D

Virtual 3D city models allow not only a three-dimensional representation of relevant city objects, but also provide a harmonized and standardized source of different data for the urban space and energy planning. play an important role in building that are responsible for the majority of energy consumption in cities. For the planning of sustainable and energy-efficient cities, it is important, as precisely as possible to know about the current and future energy needs of each building communication.

Dr. Giorgio Agugiaro who concerned himself as a postdoc at the AIT Center for Energy intensively with issues of data integration, outlines an example: "For the test district of Meidling we could integrate numerous records of the City of Vienna for the first time in a virtual 3D model. In this model, for example, for each building information such as year of construction, volume, gross floor area, number of inhabitants, already installed solar panels, and solar radiation values ​​contain. "This can further characteristics such as heating demand, energy class and CO2 emissions calculated at different renovations and easily appear three dimensional. This is visible at a glance, areas where restoration is needed.

Indispensable are those standardized data platforms also for calculating the future energy needs and the planning of appropriate supply infrastructure. Here it will be necessary in the future, in the field include the growing momentum of renewable energy and energy efficiency in planning and upgrading of electricity or district heating networks.
