Urban digital twins have become an essential factor for cities and communities to visualize, simulate and analyze data. The conventional geospatial standards work great with online platforms such as CesiumJS or ArcGIS API for JavaScript. However, their usage in different platforms such as game engines has not been well established yet. Game engines...

As the world has more urbanized, cities need to assess and manage their building energy performances in order to achieve energy-reduction goals. The urban digital twins (UDT) offer promising solutions to this demand by providing valuable insights with qualitative and quantitative information about the building environment. The urban building energy...

This work assesses the role of biomass and municipal solid waste in isolated energy systems. For this, La Réunion, a French overseas territory in the Indian Ocean with a population of about 850,000, serves as a case study. Methodically , the study assesses technical biomass-based potentials based on an island-wide digital landscape model, detailed...

Addressing the gap between available urban building data, energy performance evaluation, and spatial distribution of end-users is a growing concern of municipalities to support urban energy planning and retrofitting towards low carbon emission strategies. These days, many existing urban building energy models (UBEM) use the non-geo-specified 3D bui...

The OGC Interoperable Simulation and Gaming Year 2 Sprint advanced the use of relevant OGC and Khronos Group standards in the modeling, simulation, and training communities through capability development, compatibility testing, and gap analysis. Of particular interest was the use of glTF models, game engines, and 3rd-party mobile device libraries f...

This paper explains the development of a 3D city model-based Public Participation Platform as a prototype and its implementation in a real-world public participation process to redevelop the Weilimdorf area of Stuttgart city. Alongside conducting Weilimdorf’s public participation process, the goal of the mentioned public participation platform is t...

This paper explains the first insights into the ongoing development of a CityGML based Food Water Energy Application Domain Extension (FWE ADE). Cities are undergoing rapid expansion throughout the globe. As a result, they face a common challenge to provide food, water and energy (FWE) supplies under healthy and economically productive conditions....

In the face of climate change and the energy transition that the German federal government is aiming for, all renewable energy potentials need to be tapped. Unfortunately, small wind turbines play a niche role in Germany and most other countries despite the fact, that although they offer advantages as e.g. almost seasonal independent energy product...

The projected increasing population in cities and metropolitan regions results in higher demands of resources, i.e., food, water, and energy (FAO 2018), that are essential for human well-being, poverty reduction, and sustainable development (Hülsmann and Ardakanian 2018). There are clear interactions between water, food, and energy that may result...

Cities are undergoing rapid urbanisation throughout the globe. A common challenge amongst them is to provide food, water, and energy (FWE) supplies under sustainable and economically productive conditions. As a result, new tools and techniques must be developed to support domain experts and decision-makers to understand, simulate and visualise the...

A quantitative assessment of food-water-energy interactions is important to assess pathways and scenarios towards a holistically sustainable regional development. While a range of tools and methods exist that assess energetic demands and potentials on a regional scale, the same is not true for assessments of regional food demand and potential. This...

The paper explains a workflow to simulate the food energy water (FEW) nexus for an urban district combining various data sources like 3D city models, particularly the City Geography Markup Language (CityGML) data model from the Open Geospatial Consortium, Open StreetMap and Census data.
