About us

More comfort with less energy consumption

“Hydronic system optimisation”, better known as Hysopt. Founded in 2013 as a spin-off from the University of Antwerp, Roel Vandenbulcke (CEO and founder) wanted to change the status-quo when it came to carbon emissions. Now, we are making an impact on tackling climate change. Our weapon of choice? Your HVAC installations!

Our story

Hysopt is a unique design software that helps building managers get the most out of their heating and cooling systems. Most of the time, these systems are still underperforming and over-polluting.

Buildings account for 40% of energy consumption and no less than 36% of CO₂ emissions.  Therefore, heating and cooling buildings more efficiently is our answer to global warming. By doing so, in collaboration with our Hysopt partners, we could drastically reduce CO₂ -emissions and cut energy costs enormously all at the same time.

There is still a deep-rooted misconception that investing in sustainability is extremely expensive, but we learned from experience that we can help you save an average of 40% CO₂- emissions and 30% on energy bills. Few people are aware of just how drastically you can reduce your operational costs and/or CO₂ -emissions by optimising your HVAC system.

Not to mention that the thermal comfort of your building has a massive impact on the well-being and productivity of people!
