Optimising heating, cooling, and ventilation systems using physics-based simulation

Updated by Onye Dike on May 9th, 2026
Hysopt is a Belgian HVAC (Heating, Ventilation, and Air Conditioning) engineering platform developed to help engineers, consultants, and building owners design and optimise heating, cooling, and ventilation systems using physics-based simulation. Originally created from founder Roel Vandenbulcke’s doctoral research, the platform focuses on modelling real operational behaviour rather than relying solely on static HVAC calculations. In recent years, Hysopt has increasingly positioned its software around building decarbonisation and carbon reporting, enabling users to quantify operational emissions, compare retrofit scenarios, and evaluate electrification strategies. The platform is used in commercial building projects to support energy optimisation, ESG reporting, lifecycle analysis, and low-carbon HVAC system design.

Core Features

Hysopt approaches HVAC engineering through digital twin modelling and dynamic simulation rather than traditional component-level calculations alone. The platform is designed to help engineering teams assess how HVAC systems behave under real operating conditions, allowing them to evaluate energy performance, operational carbon emissions, and decarbonisation pathways. Accordingly, its main features include:

  • HVAC Digital Twin Simulation — Models heating, cooling, and air-handling systems dynamically to simulate real operational behaviour across varying load conditions.

  • Operational Carbon Analysis — Quantifies HVAC-related emissions using simulation-based calculations rather than spreadsheet estimates or static assumptions.

  • Retrofit Scenario Modelling — Compares decarbonisation pathways including heat pumps, hybrid HVAC systems, low-temperature heating, and phased retrofit strategies.

  • ESG and Compliance Reporting Support — Produces traceable simulation outputs intended to support ESG reporting, funding applications, tender responses, and Fit-for-55 alignment.

  • Lifecycle and Embodied Carbon Assessment — Supports operational and embodied carbon analysis using lifecycle modelling approaches and HVAC system evaluation tools.

  • BIM and Engineering Workflow Integration — Connects HVAC calculations and simulation data with BIM environments and Autodesk AECO workflows.

Closing Insights

Hysopt was founded in Belgium in 2013 as a spin-off from the University of Antwerp, based on research by founder Roel Vandenbulcke into dynamic HVAC system simulation. The company’s core premise is that many HVAC systems underperform because traditional engineering methods focus too heavily on individual components rather than system-wide operational behaviour. Hysopt’s platform therefore centres on physics-based digital twin modelling intended to predict how HVAC systems perform under real-world conditions.

The company has increasingly aligned its platform with building decarbonisation and carbon reporting requirements. Its recent publications place strong emphasis on measurable operational emissions, ESG reporting, lifecycle carbon assessment, and electrification readiness for commercial buildings. Hysopt argues that simulation-based modelling provides more reliable carbon accounting than conventional spreadsheet estimates, particularly for retrofit projects and public-sector tenders requiring traceable emissions analysis.

Hysopt also supports broader net-zero transition planning. The platform enables analysis of low-temperature heating systems, heat pump integration, hybrid HVAC strategies, and portfolio-wide retrofit planning. According to the company, these capabilities help organizations quantify carbon reduction potential, evaluate lifecycle costs, and support compliance with emerging ESG and building performance regulations.
