Abstract:
This paper introduces a web-based application that visualizes building specific simulation results regarding renewable potentials and economics for entire city quarters. Focusing on the building stock, this application enables decision-makers to consider energy related aspects in early-stage city quarter planning. The application builds on the existing energy simulation platform, SimStadt, which allows the detailed assessment of buildings’ energetic performance or photovoltaic rooftop potentials based on 3D CityGML models. A new, user-friendly and browser-based graphical user interface (GUI) makes energetic modeling more accessible and independent of a user’s operating system. Furthermore, a customizable economic analysis was added to the pre-existing workflow to calculate rooftop PV potentials, allowing the evaluation of renewable energy potentials with their associated total investments or levelized cost of electricity (LCOE) at building level. Combined, these improvements create n
ew use cases for modeling environments previously reserved for researchers, such as enabling utilities and their house-owning customers to identify PV potentials and costs, or PV project developers to more easily and accurately locate neighborhoods with high potential. Further functionalities such as building heating and cooling demand assessment will be included in a next step to extend the scope of this application towards a versatile urban energy system simulation platform.
