The Physics-Based HVAC Engineering Software

The HVAC simulation and calculation software, to streamline your design process and optimise your building's heating and cooling installations. Take actionable steps towards greener zero carbon initiatives.

Deliver optimal HVAC systems while improving your margins

In today's constantly evolving HVAC market, navigating the intricacies of heating and cooling systems can be quite daunting. There is an emerging need for high-efficiency HVAC systems, but at the same time, the complexity of systems is rapidly increasing. At Hysopt, we tackle this exploded complexity with our own innovative physics- and cloud-based software.

By approaching HVAC engineering on a system-level instead of looking at individual components, we empower HVAC Engineers to design and optimise HVAC systems for maximum efficiency and performance. Our cutting-edge software not only enhances system functionality – driving sustainability and cost savings - but also streamlines your overall engineering process.

Experience the difference of system-level thinking with Hysopt, and revolutionise your approach to HVAC engineering to achieve unparalleled results.

Here's what our customers have to say:

With the growing emphasis on electrification as a means to achieve decarbonisation goals, we sought a solution that would give us the tools to design and analyze the increasingly complex systems associated with this transition.

By leveraging Hysopt's software, we can achieve our project goals and design low carbon HVAC systems. The added value of Hysopt lies in its ability to optimize all parts of the hydronic systems and provide the insights needed over the full range of operation to navigate the complexities of HVAC electrification and deliver sustainable, high-performance solutions.
Hysopt's support has been instrumental for us at Hi Group, ensuring we're equipped every step of the way. Our junior and less confident designers are accelerating their learning curve! With Hysopt, they're experimenting with new concepts and gaining instant feedback, boosting their skills and confidence.

Thanks to Hysopt, we're now witnessing consistently high-quality designs emerging from the design team, revolutionising our approach to projects and enhancing our reputation. At Hi Group, we're thrilled with the transformation Hysopt has brought to our team and projects. It's been an incredible journey of growth and innovation!
We are thrilled that our partnership with Hysopt will allow us to enhance the efficiency of our clients' heating systems and prepare them for the adoption of low-carbon alternatives like heat pumps.

Through our collaboration, we can offer our clients tailored solutions with clear, quantified benefits and costs, enabling them to reduce energy consumption and lower carbon emissions. Hysopt's precise modelling capabilities ensure that projected savings translate into tangible real-world results.
At Insite Energy, our priority is to ensure that, even when the initial design and build is good, that efficiency is maintained throughout the entire lifecycle of a heat network. Where that's not the case, we assess whether components need replacement or if other changes are required that might be more cost effective.

Since incorporating Hysopt into our way of working, our engineering process has definitely improved. Whenever I suspect a problem in an existing system, I like to run it through Hysopt to see what output it gives me. The greatest benefit of using Hysopt is its ability to eliminate uncertainties, allowing us to efficiently and effectively identify and address all system issues.
In the past this was a long trial and error process to commission an installation. With the Hysopt software, we have saved 50% on commissioning time thanks to the presets and setpoints being automatically calculated.
