Define the requirement
Enter room, system or fixture inputs and calculate the engineering requirement for the selected module.
MEP design software
MEP design software for faster mechanical calculations and layouts
MEPFlow helps mechanical engineers connect HVAC duct sizing, ventilation, diffuser selection, plumbing pipe sizing and hydronic workflows in one browser-based platform.
Free to start. Built for mechanical design workflows in Canada and the United States.
Move from isolated calculations to a connected workflow
MEP design often means moving the same values between spreadsheets, reference tables and drawing tools. MEPFlow is being built to reduce that repetition: calculate a requirement, carry the result into the next design decision and keep the engineering trail understandable.
Connect ventilation, duct, air-distribution, plumbing and hydronic work instead of rebuilding inputs.
Use transparent engineering methods and reviewable results rather than a black-box answer.
Work in a browser with no desktop installation and start on the free plan.
Support both Canadian and US project workflows while retaining engineering judgement.
A practical MEP design workflow
Size the system
Turn airflow, flow or demand into duct, diffuser, plumbing or hydronic sizing decisions.
Review and document
Check assumptions, warnings and results before carrying the design into project deliverables.
Who MEPFlow is built for
Mechanical consulting firms looking to standardize repeatable calculations across a team.
MEP engineers and designers who want faster early-stage sizing without losing visibility into the method.
Canadian firms working with fixture-unit plumbing and North American HVAC workflows.
Small firms and independent engineers that need accessible browser-based engineering tools.

ExploreFrequently asked questions
What does MEP software do?
MEP software supports mechanical, electrical and plumbing design tasks. MEPFlow currently focuses on mechanical workflows including ventilation, ductwork, diffuser selection, plumbing pipe sizing and hydronic sizing.
Is MEPFlow intended to replace engineering judgement?
No. The software helps automate repeatable calculations and exposes inputs and results. The engineer remains responsible for codes, assumptions, coordination, equipment selection and final design decisions.
Does MEPFlow support Canadian projects?
Yes. MEPFlow is a Canadian product and includes workflows relevant to Canadian mechanical design, including fixture-unit plumbing. Users must still verify the applicable provincial code and authority requirements.
Is MEPFlow free?
MEPFlow is currently free to start. The public calculators can also be used without creating an account.
