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
System check
Automatic validation of your initial design for concept mistakes, hydraulic compatibility and potential missing components.
Dynamic simulation
Dynamic simulations of the installation performance in variable conditions to help evaluate the design’s energy consumption, thermal comfort and gain control.
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.
Optimal component selection
Automated iterative algorithms for optimal sizing of all installation components, taking a whole system approach into account.
Commissioning
Automated hydraulic balancing of your system. With the calculated presets of all system components and a reporting for faster commissioning of the build installation.
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.
Discover all features
Great usability for every team member involved
Intuitive interface
Specific intuitive interface developed for HVAC designers and M&E consultants
Powerful cloud servers
Our cloud servers supply all needed calculation power, and allow to automatically scale when required.
Fully web based
Fully web based software, so no software installations or migrations. Always works with the latest available release.
Support
Direct support integrated in the software, and able for remote interventions when required.
Work with colleagues
Collaborate with colleagues or stakeholders via a shared folder system.
Control all access
Company license (multi-user) access management over the software.
