Hysopt Designer: HVAC System Design Software for Energy Efficiency and Precision
For HVAC engineers and consultants designing energy-efficient systems: Model, calculate, and validate complete HVAC installations with a powerful physics-based platform. Reduce oversizing, cut CO₂ emissions, and eliminate costly design errors—before installation begins.
Design, Validate and Calculate HVAC Systems with Confidence
Hysopt Designer is an advanced HVAC system design software that allows engineers and consultants to model, simulate, and optimise complete heating and cooling installations. Using intuitive P&ID modelling, you can create accurate system layouts while maintaining hydraulic integrity with built-in validation checks. The platform supports energy-efficient HVAC design by automating calculations for system capacity, pipe sizing, volume flow, temperature propagation, and control logic.
With access to a proven concepts library and integration-ready BIM outputs, Hysopt Designer helps reduce oversizing, cut energy and CO₂ costs, and eliminate design errors—before the project reaches the site.
