I made a free Excel air change calculator for commissioning engineers.
Hi everyone,
I wanted to share a free Excel tool I've developed called AirChange Basic.
I built it during my third-year mechanical engineering placement, where I worked as an HVAC commissioning engineer in a hospital.
I found myself repeatedly calculating air changes per hour, so I decided to make a simple tool to speed things up and reduce mistakes on site.
The goal of AirChange Basic is to make those calculations quicker and easier for any fellow engineers, technicians or interns carrying out air balancing.
I've put together a short 2.5-minute video showing how it works, and the Excel calculator is completely free to download and use.
I'd really appreciate any feedback from people working in the industry.
If you notice any bugs or have ideas for improvements, please let me know, I'd love to keep improving it.

Thanks, and I hope some of you find it useful!
