MEP Design Built for Consultant Workflows

h2x puts system design, calculations, sizing and project outputs in the same browser-based workspace. There's less jumping between PDF markups, spreadsheets and drafting tools as the job develops.

CONSULTANT WORKFLOWS

Reduce Design Time, Rework and Review Friction

A typical MEP workflow can end up split between PDF markups, spreadsheets and drafting tools. When something changes, the same information may need checking in several places. In h2x, the design, calculations and sizing stay together, so reviews are simpler and there's less chance of an update being missed.

Fewer Disconnected Tools

Bring system layouts, calculations and sizing together in one connected project instead of across separate tools.

Less Manual Rework

Update designs without rebuilding calculations across separate spreadsheets, markups and calculation files.

Easier Design Reviews

Review system sizing and engineering results alongside the design for faster, clearer project checks.

Fewer Missed Updates

Keep design information aligned as layouts, assumptions and project requirements change throughout the project.

From Concept to Coordination in One Workflow

Start with the layout, work through the calculations and sizing, then review, revise and export from the same project. You're not rebuilding the engineering every time you move to the next stage.

DESIGN CAPABILITIES

Design the Systems Your Projects Need

Use h2x for HVAC, plumbing and fire design in the same project. The layout and calculations sit together, so engineers can work across systems without constantly switching between separate tools.

HVAC Design

Design heating, cooling, ventilation and hydronic systems directly over project drawings. Calculate loads, size ductwork and pipework, and review results as the design develops.

Design and Calculations in One Workflow

MEP design can become fragmented when layouts, calculations and sizing are handled in separate tools. Engineers often have to transfer information manually between drawings, spreadsheets and calculation files.

In h2x, the layout and engineering sit together. Change the design, check the numbers and carry on working without having to enter the same information somewhere else.

Connected Design & Calculations

Lay out systems and complete engineering calculations within the same project.

Less Manual Data Transfer

Reduce the need to copy information between drawings, spreadsheets and separate calculation tools.

Results in Context

Review sizing and engineering results alongside the system they relate to.

Change the Design Without Starting Again

Architectural layouts rarely stay fixed throughout a project. When backgrounds, equipment locations or system routes change, disconnected workflows can create another round of manual updates.

Because the calculations relate to the system you've drawn, you can update the layout and then check what those changes have affected instead of rebuilding calculations in separate files.

Update Project Layouts

Replace architectural backgrounds and adjust systems as the building design develops.

Review Affected Calculations

Check how design changes influence system sizing and engineering results.

Reduce Repetitive Rework

Keep developing the same project instead of recreating calculations in separate files.

Make Design Reviews Clearer and Faster

Design reviews are harder when the drawing, calculations and sizing information sit in different places. Engineers need a clear way to understand how a system has been designed and identify potential problems.

With the technical data next to the design in h2x, reviewers can follow the engineering without hunting through separate files. Warnings draw attention to anything that needs another look, while comments let teams leave feedback within the project.

Review Engineering Results

Inspect loads, flows, pressure losses, velocities and calculated sizes alongside the design.

Identify Issues Earlier

Use warnings and engineering information to highlight areas that may need attention.

Leave Feedback in Context

Add comments directly within the project so review feedback stays connected to the design being checked.

PROJECT OUTPUTS

Create Outputs Your Team Can Actually Use

A completed design needs to be easy to review, share and coordinate. Turn your h2x project into clear branded drawings, engineering reports and Bills of Materials, then continue coordination in AutoCAD and Revit when required.
