Hysopt Optimiser

From component to system thinking

Many HVAC installations underperform and over-pollute. Designers operate at the best of their ability, but often lack powerful tools to make dynamic system behaviour transparent. Problems arise at system level, because mathematical calculations to correctly select and size components are made more complex due to the integration of low carbon technologies. 

Hysopt uses a unique calculation and simulation software to increase HVAC performance, reduce carbon emissions and save energy costs. 

Our solution

Digital Twin software for HVAC deep system calculation

Our software enables  the possibility to create HVAC systems in a VIRTUAL environment before building or renovating in real life.

Our full system mathematical model describes all applicable laws of physics (thermal, hydraulic, control, dynamics). No concessions on system or calculation complexity.

Main functionalities

Play Video

System check

Automatic validation of your initial design for concept mistakes, hydraulic compatibility and potential missing components.

Play Video

Dynamic simulation

Dynamic simulations of the installation performance in variable conditions to help evaluate the design’s energy consumption, thermal comfort and gain control.

Play Video

Pareto analysis

Compare different system alternatives in the Pareto dashboard. Compare system KPI’s to create an economical and an ecological optimum to objectify the best fitted solution.

Inspiration library

Template library with preprogrammed hydraulic base circuits and a best practice control strategy. Ready to use in your existing or new build installation.

Play Video

Optimal component selection

Automated iterative algorithms for optimal sizing of all installation components, taking a whole system approach into account.

Play Video


Automated hydraulic balancing of your system. With the calculated presets of all system components and a reporting for faster commissioning of the build installation.

Play Video

Sensitivity analysis

Investigate how design changes affect the overall system performance. Make multiple variants of your model, each with minor parameter changes and all the design calculations and dynamic simulation will be automatically executed.
