Abstract
Ziel des Projektes ist die zuständigen Stellen dabei zu unterstützen Strategien zu entwickeln, die mit den Zielen der EU zur Nutzung der erneuerbaren Energien und Reduzierung von CO2-Emissionen im Einklang stehen.
Im Rahmen des OpenGIS4ET wurde das online Planungstool Citiwatts 3.0 entwickelt, eine Open-Source-Plattform für die Energieplanung, die die grüne Wende in den Bereichen Heizung, Kühlung, Mobilität und Sektorkopplung vorantreibt. Das Tool basiert auf der Vorgängerversion, die im Rahmen des Horizon 2020 Projekts Hotmaps entwickelt wurde.
Zu den wichtigsten technischen Errungenschaften zählen das DevSecOps-Framework, responsives Design, fortschrittliches Sitzungsmanagement, Zwei-Faktor-Authentifizierung und eine sichere öffentliche API. Die Plattform umfasst drei Kernmodule: ein EV-Mobilitäts-Tool mit Kartierung der zurückgelegten Fahrzeugkilometer und Ladeszenarien, ein Fernwärme-/Fernkälte-Tool mit Temperaturoptimierung und ein Sektorkopplungs-Tool, das Strom-, Heizungs- und Verkehrssysteme über EnergyPLAN integriert.
Das Projekt umfasste eine umfassende CO2-Folgenabschätzung, automatisierte Datenqualitätsvalidierung, DSGVO-konforme Vorlagen und Exportfunktionen (PDF, ZIP, Excel). Die Open-Source-Architektur reduziert Marktbarrieren, während Schulungsprogramme in den Partnerländern neue Kompetenzen aufgebaut haben.
Die Validierung in der Praxis erfolgte durch Fallstudien in Dänemark, Österreich, der Schweiz und Deutschland sowie durch Sommerschulen. Peer-Review-Publikationen dokumentierten Innovationen in den Bereichen EV-Ladeanalyse, Fernkühlungsnetze und Integration erneuerbarer Energien.
The OpenGIS4ET project successfully delivered the Citiwatts 3.0 platform, a comprehensive open-source energy planning tool that advances the green transition across heating, cooling, mobility, and sector coupling domains. Building on the former H2020 Hotmaps foundation, the project achieved its core objective of creating an accessible, interoperable platform for public authorities and energy planners operating from local to national scales.
The project established a robust DevSecOps development framework ensuring security throughout the development lifecycle, with SonarQube integration for continuous code quality monitoring. The platform features responsive design compatibility across desktop and mobile devices, advanced session management enabling users to maintain multiple calculation results per module, and comprehensive two-factor authentication through Keycloak services. A secure public API also enables external system integration.
Sophisticated calculation modules were developed and validated through real-world case studies:
The EV-Mobility tool provides Vehicle Kilometer Travelled mapping with charging behavior modeling across four scenarios including home, workplace, points of interest, and home office charging, coupled with photovoltaic production potential analysis.
The District Heating and Cooling tool addresses temperature-level optimization requirements with economic feasibility assessment tools.
The Sector Coupling tool integrates electrical, heating, and transport systems through connection with EnergyPLAN, enabling comprehensive flexibility analysis for multi-sector energy planning.
The project delivered a comprehensive CO2 impact assessment and quality control processes applicable to future energy planning initiatives. Open dataset repositories with automated quality validation ensure data integrity, while GDPR risk analysis templates provide reusable compliance frameworks for similar European energy planning tools. Export capabilities, which include PDF reports with indicators and charts, ZIP packages, and Excel format compatibility for external analysis, extended the original platform capabilities.
The platform's open-source architecture reduces market entry barriers. A usability analysis has been conducted and was followed by the implementation of release 3.0 with UX improvements. Training programs delivered to energy planning professionals across partner countries established new competency frameworks, while comprehensive documentation and tutorial materials support ongoing knowledge transfer. Case studies across Denmark, Austria, Switzerland, and Germany confirmed the platform's effectiveness in diverse regulatory and technical contexts. Summer schools with 250 participants across multiple events validated usability improvements and demonstrated practical applications in academic and professional settings.
Peer-reviewed publications document methodological innovations in spatiotemporal electric vehicle charging analysis, district cooling network assessment, and renewable energy integration strategies. Academic integration at the University of Applied Sciences Western Switzerland will ensure ongoing educational impact, while wiki documentation and training materials support adoption beyond the project timeline.
The platform's success enabled additional major projects: OpenMod4Africa extending energy planning capabilities to serve 500 million citizens across West and East Africa, the OFPP project addressing microgrid resilience planning, and participation in the Horizon AI4SoftEng project through API integration for Swiss validation use cases. Derived projects such as CoolLIFE and SAPHEA also display the adaptability of the current platform, which demonstrates its adaptability to diverse geographical and technical contexts while maintaining the core open-source principles and community-driven development approach.
