Built for mechanical design
Practical HVAC tools that turn room inputs into clear calculations, organized schedules, and reports you can put to work.
Built by mechanical engineers, for mechanical engineers.
| Room | Area · ft² | Exposure | CFM |
|---|---|---|---|
| 101 / Office | 200 | Interior | 300 |
| 102 / Office | 320 | Interior | 480 |
| 103 / Meeting | 180 | Exterior | 450 |
01 / The toolbox
Focused tools for the calculations you repeat. Start with room airflow. Build from there.
Bring ventilation requirements, sensible equipment heat, and area estimates into one room-by-room workflow.
Room volume, refrigerant charge, and ASHRAE 15 analysis.
Pipe sizing, pressure drop, and glycol considerations.
Airflow, duct sizing, velocity, and pressure loss.
02 / From inputs to deliverable
Define the area, height, exposure, and applicable requirements. Keep the inputs and assumptions together.
Compare the airflow methods. Review each room, its governing value, and the basis behind it.
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
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.
One toolbox. A clearer path from calculation to documentation.
