List of the Top Mechanical Engineering Software for Chromebook in 2026

h2x is a building services engineering software platform designed to automate mechanical, plumbing, HVAC, and fire protection system design and calculations. The platform combines interactive drawing tools with engineering calculations so users can develop system layouts and evaluate their performance within the same workspace. Its HVAC design capabilities include heating and cooling load calculations, duct sizing, ventilation layouts, chilled water systems, and hydronic heating design. Plumbing design tools support domestic hot and cold water distribution, sanitary drainage, stormwater management, and gas piping systems. Fire protection features enable engineers to design and size sprinkler networks, hydrant systems, and hose stations. Automated calculations determine pipe and duct dimensions, flow rates, velocities, pressure losses, and equipment duties based on system configurations. The software incorporates engineering calculation methodologies aligned with industry standards, including ASHRAE and CIBSE guidance. When users modify pipework, ductwork, components, or design parameters, h2x updates the associated calculations to reflect the revised layout. Its 3D visualization tools allow engineers to inspect building services systems, identify coordination issues, and review design characteristics using graphical representations. Documentation capabilities include branded PDF drawings, heat load reports, system sizing reports, bills of materials, and exports to AutoCAD and Autodesk Revit. h2x supports engineering consultants, mechanical contractors, plumbing designers, and construction professionals throughout building services design, technical review, cost estimation, and project documentation.
