What’s the Difference between Vabi and Hysopt?
Vabi is well-known for reliable static energy calculations. It gives engineers a clear baseline for heating and cooling loads — essential for early-stage sizing and compliance checks.
But here’s the catch:
Vabi doesn’t test or optimise the actual HVAC system design that will deliver those loads in practice.
Hysopt fills that gap. It uses static loads as a starting point, then adds dynamic thermal, hydraulic and control simulation to help you right-size, balance and verify your entire system — long before it’s built.

Why HVAC Engineers Choose Hysopt
1. Beyond Static Loads
Vabi gives you load numbers — Hysopt turns them into a working HVAC system with dynamic flows and control logic tested upfront.
2. Find Hidden Oversizing
Manual static calculations often oversize systems. Hysopt’s simulation and balancing engine fixes this before it wastes energy.
3. Prove Real Savings
Hysopt delivers clear, data-backed CO₂ and energy savings reports — not just estimates.
