Overview
Hysopt builds a physics-based HVAC engineering platform that engineering teams use to design, simulate and validate hydronic HVAC systems before construction. The company was founded in 2013 as a spin-off from the University of Antwerp by Roel Vandenbulcke. Its headquarters is at Luchthavenlei 7A in Deurne, Antwerp, and it has a second office on Great Portland Street in London. The product range includes Hysopt Designer, Hysopt Simulator, Hysopt Feasibility, Hysopt Calculator and Hysopt BIM Syncer, plus DeltaT AI, an HVAC engineering copilot built into the platform. Hysopt is an Autodesk AECO Technology Partner and a CIBSE Patron. The software has been deployed on more than 550 HVAC projects, and engineering teams across Europe, North America and the Middle East use it. The company reports an average CO2 reduction of 40% and average energy savings of 30% on its projects. Customers and users shown include BuroHappold, Equans, Foster Partners, Mott MacDonald, Siemens, SPIE, Sweco, Vattenfall, Veolia, Kuijpers, Unica and Mitie. The leadership team consists of Mark Lewis as CEO, Joa Oris as CTO, Jurgen Van Ham as CFO & CPO and Brian Wimberley as CMO. Hysopt has more than 20 employees.

- A good design can still perform poorly once it meets the real world.

Will it recover after a failure? Will the promised energy, carbon and comfort results actually appear in operation? Those answers shouldn’t arrive after handover. Performance criteria, measurement points and commissioning settings need to be defined while the design can still be changed. That means moving 𝗳𝗿𝗼𝗺 𝗱𝗲𝘀𝗶𝗴𝗻
- We’ve just wrapped up another Bootcamp at our HQ in Antwerp! Last week, the group got hands-on with Hysopt and worked through real HVAC design challenges, from hybrid systems and heat pumps to cascade design, secondary-side optimisation and installations combining heating and cooling. Questions got asked, different approaches got compared, and participants shared how they would tackle similar challenges in their own projects. On Friday, they brought it all together in a final application exercise before receiving their
