Hysopt

Hysopt is a physics-based HVAC engineering platform that helps engineers design, validate and optimise hydronic HVAC systems with confidence—before construction begins. Built around a single hydronic HVAC digital twin, Hysopt replaces fragmented spreadsheets, disconnected tools and engineering assumptions with one connected workflow that spans feasibility, design, simulation, component selection, commissioning and BIM. Engineering teams use Hysopt to reduce oversizing, eliminate engineering rework, validate hydraulic performance, compare design alternatives and optimise CAPEX, OPEX and CO₂ before decisions are locked in. The result is faster engineering, lower project risk and HVAC systems that perform as intended in the real world. Whether you're preparing a tender, designing a hospital, simulating a data centre, commissioning a district energy network or delivering a decarbonisation project, Hysopt helps you make better engineering decisions backed by physics—not assumptions. Our platform includes dedicated applications for: • HVAC Feasibility & Optioneering • HVAC Design • Dynamic HVAC Simulation • Component Selection & Commissioning • BIM Synchronisation • DeltaT AI, your built-in HVAC engineering assistant Used on more than 550 HVAC projects across Europe, North America and the Middle East, Hysopt helps MEP consultants, design-build contractors, energy engineers and technical building owners standardise engineering quality, accelerate delivery and prove real-world HVAC performance. If it works in Hysopt, it works on site.
