How it works

From project inputs to defensible energy scenarios in one workflow

See how engineering, utility, and public-sector teams use Sympheny to bring inputs together, optimise across thousands of options, and deliver decisions stakeholders can stand behind.

How Sympheny works

A four-step workflow, from project inputs to client-ready outputs.

The same platform takes you from raw project inputs to optimised scenarios to a report you can hand to a client — without rebuilding the model in between.

01

Bring project inputs together

Pull demand profiles, site characteristics, tariffs, and benchmarks into a single project. Locally relevant assumptions are configured per region, so teams start from a defensible baseline instead of stitching together spreadsheets.

Building-level GIS and demand data pulled in automatically — every project starts as a digital twin of the site.
02

Build and optimise scenarios

Define the technologies and constraints that matter, then let the multi-objective optimiser search across 50,000+ technology and capacity combinations to find the architectures that meet your cost, emissions, and space targets.

Sympheny technology candidates: conversion technologies (Solar PV, Air-to-water HP, Gas Boiler) and storage candidates (Li-ion Battery, Hot Water Storage) listed with their input/output modes, hub and lifetime
Pick technologies from the database or define your own — the optimiser then searches the full design space.
03

Compare trade-offs

Put every optimised scenario on a Pareto Front across cost and CO₂. See the cheapest option, the lowest-carbon option, and the trade-offs in between — so the recommendation holds up to scrutiny.

04

Share client-ready outputs

Sankey diagrams, Pareto comparisons, technology investments, capacities and monthly energy flow all live in the same interactive dashboard. Apply filters, download the graphs and their data, and print straight from the browser. The project lives on as a digital twin of your site — re-run as inputs evolve, without rebuilding the model.

Explore the results in the interactive dashboard — apply filters, download the graphs and their data, build your report in minutes.

Optimise the system, not isolated components.

A heat network, PV system, storage asset, or grid connection may look optimal alone while weakening the wider energy concept. Sympheny compares integrated scenarios so teams can see system-level trade-offs before decisions are locked in.

What the output looks like

Client-ready results, built from your inputs.

Sympheny turns your site parameters into interactive Sankey diagrams, Pareto charts, and monthly energy flows — ready to share without reformatting.
