Welcome to TESSA
TESSA — the Thermal Energy System Simulation Assistant — helps you design district heating and cooling networks that are secure, cost-effective, and low-emission.
Built on more than 20 person-years of academic research and science-based innovation, TESSA supports the key steps of every DHC project.
What TESSA brings together
- Comprehensive building geo-data and machine-learning demand models
- 2050 climate scenarios for future-proof planning
- Fast thermal network layout, sizing, and simulation
- A blend of open and proprietary data sources
- Intelligent model fusion across the full project lifecycle
What you can do with it
- Get enhanced data and simulation capacity from the earliest stages of a project, before detailed surveys are available.
- Explore variants and scenarios side-by-side to reduce risk and find the best opportunities.
- Work through an efficient end-to-end workflow that saves significant time over manual tooling.
