Hysopt Calculator Hysopt Calculator is a quick-assessment tool that helps energy and HVAC professionals estimate the technical and financial impact of upgrading or decarbonising heating and cooling systems. It’s designed to support early-stage feasibility studies by providing fast, data-backed insights into carbon savings, energy reductions, and investment returns. What Hysopt Calculator Does Best Hysopt Calculator enables users to rapidly evaluate the business case for energy efficiency and decarbonisation interventions—before any detailed engineering work is done. It bridges the gap between rough estimates and high-fidelity simulations, making it an essential tool for early-stage decision-making, stakeholder buy-in, and budget planning. Key Features Fast Scenario Comparison: Easily compare different retrofit or system upgrade options and understand their carbon and energy impact. Techno-Economic Assessment: Generate estimates for energy savings, carbon reductions, CAPEX, OPEX, and return on investment. Data-Driven Inputs: Use basic building and system parameters to generate reliable results without detailed modelling. Pre-Engineering Analysis: Support decarbonisation roadmaps and funding proposals before full-scale simulation or design begins. Exportable Results: Share insights in clear, structured reports for stakeholder discussions and decision-making. Who It’s For Hysopt Calculator is suited for: Energy managers and sustainability officers building decarbonisation strategies Consultants preparing feasibility studies or funding applications Asset managers needing rapid assessments across large building portfolios Organisations planning investment in HVAC system upgrades or heat network integration
