01 / The toolbox

Your next calculation
starts here.

Focused tools for the calculations you repeat. Start with room airflow. Build from there.

A2L Refrigerant

Planned

Room volume, refrigerant charge, and ASHRAE 15 analysis.

Hydronic Design

Planned

Pipe sizing, pressure drop, and glycol considerations.

Duct Design

Planned

Airflow, duct sizing, velocity, and pressure loss.

02 / From inputs to deliverable

Less spreadsheet gymnastics.
More engineering.

01 / CALCULATE

Enter the room.

Define the area, height, exposure, and applicable requirements. Keep the inputs and assumptions together.

02 / DOCUMENT

See what governs.

Compare the airflow methods. Review each room, its governing value, and the basis behind it.

03 / MOVE ON

Carry the work forward.

Compile the room schedule and calculation reports. Keep a clear record for the next design review.

Illustrative product walkthrough. These example values are not a project design calculation.

03 / Why The Mech Shed

Built from the work
we do every day.

We’re two mechanical engineers specializing in HVAC for healthcare and pharmaceutical projects. In our work, precision is essential.

We built The Mech Shed to make repeated project takeoffs and calculations easier to manage, with clear assumptions and documentation. Read our story.

  • Visible assumptions. Know what drives the result.
  • Organized room data. Keep the project together.
  • Useful documentation. Make your work easier to review.

A practical place to get the work done.

One toolbox. A clearer path from calculation to documentation.
