The Future of Building Energy Simulation

Why use our software?

Our product replaces excel spreadsheets and disconnected simulation tools with one software that models building demand, thermal sources and hydraulics together so every scenario you present has already been tested against the numbers that matter.

Automated Network Design & Simulation

Automatically analyse, simulate & optimise networks

Get a full access to customisable buildings GIS-data files. Skip the spreadsheet relay between demand analysis, source sizing and hydraulic simulation. Planeto runs them as one connected workflow and avoid back and forth overload.

Automated network analysis and simulation

Scenario Comparison

Compare scenarios before engaging capital

Model unlimited combinations of sources, network layouts and injection points, then rank them on ROI, CAPEX, OPEX and CO₂. Be sure the option you build is the one the data actually supports.

Compare network scenarios side by side

The Online Collaboration Platform

Collaborate on shared project

Work and exchange comments from the same project instead of emailed spreadsheets. Share a link, not a file. Access the same CAPEX, OPEX and CO₂ numbers, updated in real-time.

Loved by our users

The software to give engineers and professionals the tools to plan and design thermal and geothermal energy networks for heating and cooling.

  • We needed a solution that could support our design decisions and optimize projects from the ground up. We're finally able to do just that—saving time, improving accuracy, and ensuring we make the best possible impact with each project.

  • I can calculate different variants of district heating and cooling networks 5 times as fast and write the corresponding reports. This helps my customers to make well-founded decisions without having to repeatedly place new orders for variants.
