Own the energy roadmap your council, residents, and Energiestadt assessors can stand behind.
Net-zero 2050, cantonal Energiestrategie revisions, Energiestadt re-certification, and räumliche Energieplanung obligations all land on the same small team. Sympheny gives municipalities and public-sector planners one model to compare district and city-level pathways, defend the recommendation to council and residents, and re-run scenarios as policy and budgets evolve — without re-commissioning the study.
In a 30 minute demo, see your project set up, scenarios compared, and a report ready to share.
Monthly energy flow — supply and demand aggregated month-by-month across the planning horizon.
Trusted by municipal and public energy teams
Used by Swiss cities and public energy planners to deliver räumliche Energieplanung, Energiestadt deliverables, and long-horizon decarbonisation roadmaps.
How Sympheny helps
From targets to a defensible pathway
Move from net-zero ambition to concrete district and city-level supply scenarios with cost, CO₂, and feasibility trade-offs the council can compare.
Built for political and public scrutiny
Sankey, Pareto and dashboard outputs make the trade-offs visible for committees, residents and assessors — so the recommendation holds up in the room, not just on paper.
A planning asset the city owns
The model stays with your team. Re-run scenarios as cantonal rules, energy prices, or development plans change — without going back to a consultant for every revision.
What changes for municipal energy teams
| Process | Before Sympheny | With Sympheny |
|---|---|---|
| From targets to pathways | Net-zero and Energiestadt targets are set, but the concrete routes to hit them are hard to compare side by side | Scenarios link targets to defensible district and city-level supply pathways with visible trade-offs |
| Council and resident-facing reviews | Technical assumptions are hard to explain to non-specialists — the recommendation lives or dies in the meeting | Sankey and Pareto outputs make cost, CO₂ and feasibility trade-offs easy to discuss in council and at public consultations |
| Re-certification and revision cycles | Each new policy, price update, or development plan triggers a new external study | Update assumptions in the model your team owns and re-run scenarios in days, not months |
| Consultant relationship | Eight-month studies, six-figure invoices, and a static PDF that's outdated on delivery | Consultants can work inside the same model — the deliverable is a planning asset the city keeps |
For municipalities, defensible scenarios matter.
“Sympheny supports our strategic energy planning in an ideal way. The flexibility is extremely convincing and the sensitivity analysis provides security in finding solutions.”

Public energy planning, proven in the field.
See how cities and public planners have used Sympheny to turn complex energy targets into concrete, defensible roadmaps.
Eco-quartier energy concepts and decarbonisation roadmap
Technical proof: Three scenarios mapped for an eco-quartier and city roadmap
Business outcome: 83% CO2 reduction pathway identified by 2040.
City-wide energy supply strategy toward 2050
Technical proof: 3.2 M m2 energy reference area, three time horizons modelled
Business outcome: CO2-free 2035 supply confirmed at similar life-cycle cost.
Climate-neutral research campus by 2030
Technical proof: 26 buildings across 12 energy hubs modelled
Business outcome: A living campus model that can be updated as the site evolves.
