This paper describes a methodology to assess the energy performance of residential buildings starting from the semantic 3D city model of Vienna. Space heating, domestic hot water and electricity demand are taken into account. The paper deals with aspects related to urban data modelling, with particular attention to the energy-related topics, and with issues related to interactive data exploration/visualisation and management from a plugin-free web-browser, e.g. based on Cesium, a WebGL virtual globe and map engine. While providing references to existing previous works, only some general and introductory information is given about the data collection, harmonisation and integration process necessary to create the CityGML-based 3D city model, which serves as the central information hub for the different applications developed and described more in detail in this paper. The work aims, among the rest, at developing urban decision making and operational optimisation software tools to minimise non-renewable energy use in cities. The results obtained so far, as well as some comments about their quality and limitations, are presented, together with the discussion regarding the next steps and some planned improvements.

Additional Information: The authors gratefully acknowledge the European Commission for providing financial support during the conduct of research under the FP7-PEOPLE-2013 Marie Curie Initial Training Network "CI-NERGY" project with Grant Agreement Number 606851. Research work and tests regarding the Cesium-based visualisation applications were carried out partially within the IntegrCiTy project [INTEGRCITY, 2017], which is funded by the Austrian Federal Ministry for Transport, Innovation and Technology within the framework of the ENERGIE DER ZUKUNFT/JPI Urban, with support from the European Union's Horizon 2020 research and innovation programme. As stated in section 2, some of the datasets used in this work were kindly provided by the city of Vienna specifically for the CI-NERGY project.
