Automatic MEP design software
MEPFlow keeps building loads, airflow, fixture demand, system flow and sizing connected — automatically updating ducts, pipes and system calculations as the design changes.

Explore Sanitary DrainageAutomatic loop sizing, flow and heat-output calculations.
Explore Underfloor HeatingLoads, HVAC, plumbing, hydronics, drainage and underfloor heating stay connected inside the same project. See the full MEP workflow
A closer look at MEPFlow
Loads, airflow, fixture demand, system flow, sizing and 3D review stay connected instead of being rebuilt across separate spreadsheets, calculators and files.
Connected MEP Design
MEPFlow keeps building loads, airflow, fixture demand, system flow, automatic sizing and 3D review inside the same project, so the engineering stays connected as the design develops.
Heating & Cooling Loads
Floor-plan geometry, constructions, weather, occupancy, internal gains, ventilation and design conditions are combined into one calculation workflow.
Automatic Duct Sizing
Calculated room airflow carries into the HVAC network while supply and return airflow, duct sizes, velocity, friction losses and pressure results stay connected across the system.
Automatic Plumbing Sizing
Fixture units, loading units, diversified demand, design flow, velocity and pipe sizing stay connected across cold water, hot water and recirculation systems.
3D MEP Visualization
MEPFlow turns the 2D project into a 3D building context and visualizes ductwork, domestic water, hydronics, drainage, underfloor heating and equipment inside the same connected project.

Why MEPFlow
MEPFlow keeps the engineering tied to the project so revisions do not turn into another round of spreadsheets, duplicated inputs and missed updates.
See the connected MEP workflowRoom demand, airflow, fixture demand and system flow remain tied to the calculations that size the connected systems.
Duct and pipe sizing, flow, velocity, friction, pressure and other supported results stay inside the same engineering workflow.
Loads, system layouts, sizing and review stay together instead of being spread across separate spreadsheets and calculators.
Supported MEP systems can be reviewed spatially without rebuilding the design in a separate model.
Regional methods built in
Selected region-specific sizing methods, units and engineering criteria support projects across multiple countries without rebuilding the calculation workflow around another spreadsheet.
Explore Methods & StandardsRegional fixture-unit and loading-unit methods, sizing criteria, units and supported engineering rules remain part of the same MEPFlow project.
Built for mechanical teams
Room loads, system sizing, 3D review and engineering outputs stay connected from early design through coordination.
Explore consultant workflowsDesign-build, estimating and preconstruction workflows get faster sizing and clearer system review from the same floor plan.
Explore contractor workflowsProject loads, airflow and water duty stay visible for faster equipment-selection and application discussions.
