Go to the greenpass Shop and get your greenpass Water module. The recommendation includes the default module extended with the add-on optimization. It can be further extended with other add-ons out of the categories scenarios, conditions, analysis and service.
The greenpass Team and our Urban Climate Architect (UCA) partners are happy to support you for your choice.
Submit your project information and upload your data via the online Data Upload Form. Based on your data a digital twin will be modeled with the greenpass Editor.
greenpass Water executes an automatized and high resolution expert simulation for the challenge water based on the digital twin. The digital twin out of the greenpass Editor serves as single-source-of-truth (SSOT) for the simulation. The simulation is powered by SWMM - the world's leading storm water management model.
greenpass Water automatically calculates meaningful and numerical Key Performance Indicators (KPI) for the challenge water, based on the simulation. The comprehensive results are visualized as thematic 2D water maps and temporal run-off curves and allow fact-based and data-driven decision making.
Follow the tailored and spatial located recommendations of greenpass Water to improve rainwater management and flood prevention with ease. We recommend to extend greenpass Water with the add-on optimization to get individual guidance and supervision by a certified expert in a workshop.
