Identify inefficiencies through system simulation and retrofitting analysis

  • Simulate existing system behaviour to uncover hidden inefficiencies like oversizing, short-cycling, or control mismatches.
  • Analyse retrofit scenarios side-by-side to determine the most effective path to savings and improved comfort.
  • Use KPI visualisation—energy cost, CO₂, CAPEX/OPEX—to confidently support investment decisions.

Frequently asked questions

What is HVAC design and simulation software used for?

HVAC design and simulation software helps engineers model, size, and validate entire heating and cooling systems before installation. With tools like Hysopt, users can simulate hydronic system performance, optimise configurations, and avoid design flaws—saving time and reducing failure costs.

How does Hysopt improve HVAC system performance?

Hysopt uses advanced hydronic system modelling and physics-based simulation to eliminate oversizing, optimise component selection, and balance system flow. This results in lower energy use, better comfort, and fewer issues during commissioning or operation.

Can I compare different HVAC design options in Hysopt?

Yes. Hysopt allows you to simulate and compare multiple design concepts side-by-side using a Pareto analysis. You can evaluate trade-offs in CAPEX, OPEX, CO₂ emissions, and comfort levels to support data-driven decision-making.

Does Hysopt support HVAC sizing calculations?

Absolutely. The platform automates critical HVAC sizing calculations—including flow rates, pipe dimensions, and pump selection—based on your full system model. This ensures compliance, accuracy, and faster project delivery.
Is Hysopt suitable for both new builds and retrofits?
Yes. Hysopt supports both new HVAC system designs and retrofit projects. Its simulation and validation tools help engineers adapt existing systems or design new ones with the same level of accuracy and insight.
