Introducing
topotherm

We are a startup specializing in district heating and cooling network design. Our optimisation software helps planners at utilities and engineering offices design new networks and transform existing ones into cost-effective, renewable infrastructure. Compared to conventional planning tools, our algorithms reduce lifecycle costs by 5–10% and compress days of manual design iteration into hours.

Developed from academic research at TU Munich. Validated in practice with engineering offices and utility companies.

Investment support

Our algorithms handle the four core decisions that determine whether a district heating network is technically viable and financially profitable. Underlying methods published in 6 peer-reviewed articles.

Multiple energy sources

Simultaneously optimise across solar thermal, heat pumps, waste heat, and other local sources. Our algorithms find the least-cost mix without requiring a separate simulation per scenario.

Building-specific connection

Determine for each individual building whether connecting to the network is economically justified, given its heat demand, distance, and local alternatives.

Piping routing

Automatically derive the cost-optimal pipe network layout across your target area, minimising trench length while respecting physical and geographic constraints.

Piping sizing

Select the correct pipe diameter for every segment of the network, balancing capital cost against hydraulic losses across all operating conditions.

Use Cases

Our mathematical optimisation algorithms have been validated for renewable district heating networks: developed over five years, two research projects, and six peer-reviewed publications.

Greenfield Design

Integrate multiple distributed and fluctuating energy sources locally without running tens of simulations. Define your boundary conditions and get the best possible result.

Transformation Planning

Plan how to transition to a renewable energy network maximizing profitability and reducing operating expenses.

Expansion Planning

Design and plan a financially optimal build-out plan for your existing network, giving stakeholders and customers both pricing and timing information.
