Spreadsheets vs Hysopt
From manual calculations to complete HVAC system simulation
Spreadsheets are still widely used for HVAC load calculations, pipe sizing and pressure drop calculations. But as projects become more complex, manual work, hidden errors and limited system insight quickly become bottlenecks. Hysopt replaces disconnected calculations with one integrated workflow for HVAC design, simulation, hydraulic balancing and performance validation.
What is the difference between Spreadsheets and Hysopt?
Spreadsheets give engineers the flexibility to build calculations for flow rates, pipe diameters, pressure drops and equipment sizing.But Spreadsheets don't verify how a complete HVAC system will actually perform. They cannot simulate hydraulic interactions, control behaviour or system performance under real operating conditions.
Hysopt combines calculations, hydraulic design, dynamic simulation and control strategy validation in a single environment. This allows engineers to optimise and verify HVAC systems before installation begins.

Why HVAC Engineers Choose Hysopt Over Spreadsheets
1. Eliminate Manual Engineering Work
Replace disconnected calculations with one integrated workflow for HVAC design, simulation and optimisation.
2. Catch Problems Before Installation
Validate hydraulics, balancing and control strategies before construction begins instead of discovering issues during commissioning.
3. Design with Confidence
Use simulation-based insights to right-size equipment, improve efficiency and verify system performance.
Who Benefits from Moving Beyond Spreadsheets?

How teams move from spreadsheets to Hysopt
Many engineering teams start with spreadsheets for load calculations and pipe sizing, then move to Hysopt when projects demand greater accuracy, consistency and system-level validation.
Hysopt builds on existing engineering knowledge while eliminating repetitive calculations, version control issues and manual validation work.
With Hysopt, teams can:
• Reuse existing load calculations as project inputs
• Build complete hydraulic network models
• Validate flows, balancing and controls automatically
• Optimise energy performance before installation
• Generate standardised reports and deliverables
