Hysopt Designer Hysopt Designer is a powerful digital engineering platform that helps building energy professionals design, simulate, and optimise HVAC and heating/cooling systems for maximum energy performance, comfort, and carbon reduction. Built with deep thermodynamic modelling capabilities, it provides a physics-based approach to system design—enabling you to make informed decisions with quantifiable outcomes. What Hysopt Designer Does Best Hysopt Designer enables engineers to go beyond traditional rule-of-thumb HVAC design. It allows users to create a fully transparent and data-rich model of their building’s energy system, simulate real-world performance under various conditions, and accurately compare multiple design or retrofit scenarios. The result? Optimised designs that reduce energy usage, cut carbon emissions, and improve system efficiency—backed by hard data, not guesswork. Key Features Graphical System Modelling: Quickly create complex hydraulic and control schemes using an intuitive drag-and-drop interface. Detailed Simulations: Analyse dynamic system behaviour using time-based simulations that consider load variations, weather data, and control strategies. Design Optimisation: Run automated comparisons between different system configurations and select the most efficient solution. Error Detection & Validation: Identify design flaws early through automated sanity checks and performance diagnostics. Reporting & Transparency: Generate comprehensive reports with full visibility into system behaviour, energy performance, and savings potential. Who It’s For Hysopt Designer is ideal for: HVAC consultants and engineers seeking reliable simulation tools for new build or retrofit projects ESCOs and facility managers aiming to reduce carbon and energy costs Public sector and institutional clients (e.g., universities, hospitals) with complex energy systems Anyone working on decarbonisation or energy efficiency projects for large buildings
