Synopsis: FlexPED will focus on developing an open, intelligent, and scalable energy data management and flexibility framework for city districts, using an Urban Digital Twins (UDT) platform integrated with generative AI as decision support system. The central idea is that an operational UDT platform, integrated with AI-powered agent-based simulation, can actively support stakeholders in co-developing, implementing, and monitoring adaptive and decentralised energy flexibility strategies.

Synopsis: The main goal of the RenoDAT project is to accelerates energy renovations by addressing data governance, ownership, privacy, and harmonization gaps in the implementation of Building Renovation Passports. By uniting social, technical, pedagogic, and economic expertise, the project develops a reliable data infrastructure to improve renovation quality, streamline processes, and help meet critical climate and societal well-being goals in the Netherlands.

Synopsis: The CityGML Energy Application Domain Extension (or, in short: Energy ADE) offers an open and standardised data model to facilitate multi-scale Urban Energy Modelling applications. The current version 3.0 is based on and builds primarily upon the Energy ADE 1.0, released in 2018, which has been already used in several national and international projects, mainly focusing on the simulation and computation of the building energy performance based on the integration of semantic 3D city models and other sources of information.

Synopsis: The main concept of the DigiTwins4PEDs project is to use Urban Digital Twins as a digital representation of the real world, opening up a wide range of possibilities for modeling the energy aspects of cities. This innovative approach aims to create a platform for residents and stakeholders to exchange information, enabling them to visualize various PED scenarios before their actual implementation.

Synopsis: Goal of the project is to evaluate pros and cons of existing algorithms (e.g. their requirements, their accuracy, and their performance), to compute party walls from LoD2 buildings in the 3D BAG, and to define a strategy to implement such a process that can be embedded in the current pipeline to generate and update the 3D BAG on a regular basis.

Synopsis: Goal of the project is to test whether and how far the CityGML standard can be adopted by the Municipality of Vienna in the context of their “Digitaler geoZwilling” (Digital geoTwin) vision. Part of the project is dedicated to mapping existing and currently in development Viennese datasets to the CityGML data model, and to develop a “Digitaler geoZwilling ADE” (Application Domain Extension) to accommodate particular, domain-specific needs of the Municipality of Vienna.

Synopsis: The VOLTA project is an EU Marie Skłodowska-Curie RISE (Research and Innovation Staff Exchange) project related to Geodata, Geomatics and Geoinformatics. The project will feature secondments, training activities and networking to facilitate knowledge exchange and career progresses in the geospatial field. The project will develop innovative solutions to (i) automatically provide metric information from images, (ii) fuse heterogeneous data coming from various sensors, (iii) segment 2D and 3D geospatial data and (iv) process large geospatial datasets in the Cloud.

Synopsis: The benchmark investigated the available technical solutions to support research and activities related to GeoBIM, through the use of the open standards such as IFC (by buildingSMART) and CityGML (by OGC).

Synopsis: Developers of urban energy tools have created their own tailor-made data-models, while municipalities and other urban information data administrators have their own database structure to collect and manage urban information. As such, these models exist without interoperability and exchange possibilities between the stakeholders, tools and expert fields. The CityGML Energy ADE aims to extend CityGML in order to model and store all relevant energy-related data for space heating and cooling simulation and audits, building occupancy modelling, energy system modelling, solar energy analysis, etc. It deals with different data qualities, levels of details and urban energy models complexities.

Synopsis: The Utility Network ADE extends the international standard CityGML offering a general, harmonised data model for the modelling of any utility network in semantic 3D city models. The Utility Network ADE defines a topological network model facilitating sophisticated analyses and simulations on utility networks and supplying infrastructures. Included are, among others, network hierarchies of arbitrary depth, nesting of network components, and modelling of multi-modal networks. Furthermore, it allows for representing the network components as 3D topographic city objects.

Synopsis: Nowadays, energy supply networks in cities – natural gas, electricity and heating/cooling – are almost always planned and operated separately from each other. This “silo-like” approach prevents energy utilities and city planners from: a) Identifying synergies opportunities among the networks, as to increase reliability and robustness of energy supply; b) Optimally planning heavy infrastructure investments, thus taking into account future energy demand evolutions while avoiding oversizing. IntegrCiTy project’s overall aim is to foster energy networks interoperability either in existing or future urban infrastructures by developing a dedicated decision-support tool, that shall be applied and tested/validated in three Swiss and Swedish cities (Geneva, Vevey and Stockholm). All three cities are modelled in CityGML.

Synopsis: The project is a Marie Curie Initial Training Network in the FP7 of the European commission. As such, it aims to provide high level training to young researchers in the field of smart cities, and to develop urban decision making and operational optimization software tools to minimize non-renewable energy use in cities.

Synopsis: The goal of the EnerCity project is the development of a tool for energy-planning that addresses decision-makers for the city of Trento. More specifically, the project focuses on the integration of energy-related indicators for buildings within a 3D city model. These indicators are dependent on a number of geometric, semantic and topological characteristics obtained by the 3D city model and other data sources. Such indicators are aggregable, allowing also for a more general view, depending on the hierarchy level of the decision-maker. Test-case is the city of Trento.

Synopsis: 3D city and landscape models are used to estimate the incoming solar radiation and evaluate the quality of the roofs as possible location of photovoltaic panels.

Synopsis: The project aims at the multi-sensor and multi-resolution 3D documentation of the UNESCO Maya site of Copan (Honduras) and at the realization of a 3D GIS tool to visualise and query multi-resolution, semantically enriched archaeological 3D models online.

Synopsis: The project aims to reproduce precise digital replicas of some of the Etruscan tombs located in different necropolis using reality-based 3D surveying methodologies, and to present them by means of proper 3D visualisation tools.

Synopsis: The project aims at producing an accurate, detailed and photo-realistic 3D model of the 3 Cime di Lavaredo (Drei Zinnen-Three Peaks) in the Dolomites, Italy. The model is used for geological analyses and visualisation purposes.

Synopsis: The project aims at generating an accurate, detailed and photo-realistic 3D model of the archaeological site of the Terme Neroniane in Montegrotto Terme (Padova), Italy, by means of integration of GPS, terrestrial laser scanning and traditional surveying techniques.
