Deliver more energy concepts per engineer.
Energy concepts are now a high-volume part of the workload, and clients expect more scenarios with defensible assumptions. Sympheny helps engineering and consulting firms scale that output without scaling senior engineering headcount — the optimiser handles scenario preparation so your team focuses on the judgement clients pay for.
Full access for two weeks.
Detailed Sankey energy flow — every carrier, technology, and storage element traced from supply to demand.
Trusted by consulting engineering teams
Used by engineering consultancies on energy concept, feasibility, and Areal planning projects across Switzerland and beyond.
How Sympheny helps
Free up senior engineering capacity
Go from project inputs to a working scenario without rebuilding a spreadsheet first. That's senior engineering time back on the next project instead of on data prep.
More scenarios, defensible recommendations
Compare cost, CO₂, technology sizing and trade-offs on a Pareto Front — and stress-test the chosen direction across price, demand, and policy sensitivities.
Outputs your client (and their CFO) can read
Sankey, Pareto and dashboard outputs come straight from the model. No rebuilding charts in slide decks before a steering committee.
What changes for engineering teams
| Process | Before Sympheny | With Sympheny |
|---|---|---|
| Project setup | Each assignment starts with a fresh spreadsheet rebuild — senior engineers tied up on data prep instead of analysis | Structured inputs and reusable workflows — your team starts every project from a working baseline, not a blank tab |
| Scenario comparison | Two or three scenarios per project because each change is a manual rework | Pareto comparison across cost, CO₂ and technical constraints — including the sensitivity runs that make the recommendation defensible |
| Client delivery | Results translated by hand into slides and PDFs before every committee | Sankey, Pareto and dashboard outputs viewable in-app and printable from the same workflow |
| Team capacity | Adding more projects means hiring more senior engineers — a 12-month problem | Same team takes on more energy-concept work without dropping the standard clients expect |
The sensitivity analysis is what makes a recommendation stick when the client pushes back.
“Sympheny supports our strategic energy planning in an ideal way. The flexibility is extremely convincing and the sensitivity analysis provides security in finding solutions.”

Strategic energy concept for the Insel-Holligen district
Technical proof: 30+ price and demand scenarios tested
Business outcome: Infrastructure investment stress-tested before commitment.
Residential energy concept for a new housing quarter
Technical proof: 16 buildings, 3 supply variants on the same Pareto front
Business outcome: Groundwater heat pumps win once cost, CO2 and autarky are weighed together.
Green hydrogen production and sector coupling
Technical proof: Green hydrogen and sector-coupling variants optimised
Business outcome: 60% CO2 reduction and up to 26% lower life-cycle costs identified.
