Requires Expertise

You can use Sympheny to model multi-energy systems across electricity, heat, cooling, gas, hydrogen, and storage in a single optimization run. It lets engineering firms, utilities, and municipalities compare thousands of technology combinations, run Pareto cost vs. CO₂ analyses, and generate stakeholder-ready reports. The tool pulls in GIS data, hourly demand profiles, and tariff data to build a digital twin of a site, from a single building to a city-wide district, without rebuilding models from scratch between projects.

What Sympheny does

Build a digital twin of a site using GIS and building dataRun multi-energy system optimization across electricity, heat, gas, and storageGenerate Pareto front charts comparing life-cycle cost against CO₂ emissionsCreate hourly demand and tariff profiles from a built-in databaseCompare technology combinations for conversion, storage, and supply optionsExport Sankey energy flow diagrams for stakeholder presentationsModel energy scenarios at district or city scale without rebuilding from scratchProduce structured project reports directly from the optimization resultsMixed-integer linear programming (MILP) engine compares thousands of technology combinations simultaneouslySingle model covers electricity, heat, cooling, gas, hydrogen, storage, and mobility togetherPareto front chart shows cost vs. CO₂ trade-offs across all optimized scenariosGIS integration pulls building data, roof potential, and network layout into one project workspaceHourly demand profiles generated in about 1 minute versus 10 hours in ExcelDigital twin models scale from a single building to a 78-district city without rebuildingStakeholder-ready Sankey energy flow diagrams and exports generated directly from the modelNo AI or machine learning used — deterministic calculations with no supplier pre-selection
