I will ashrae 62 indoor air quality ventilation load calculation

If you just need a rough guess at how many CFM to throw at a room, this isn't for you that's how buildings end up with poor air quality complaints.

But if you need a ventilation calculation that actually meets ASHRAE 62.1 requirements and holds up at plan review, keep reading.

I calculate outdoor air ventilation requirements using ASHRAE Standard 62.1 covering occupancy-based and area-based ventilation rates, zone air distribution effectiveness, and system ventilation efficiency for commercial and multi-zone buildings. This is the standard mechanical engineers use to size ventilation systems correctly, not a rule-of-thumb estimate.

What you get: full ASHRAE 62.1 ventilation calculation report, zone-by-zone outdoor air requirements, and system-level ventilation rate summary.

Who this is for: mechanical engineers, contractors, and consultants working on commercial or multi-zone buildings needing IAQ compliance.

Who this is NOT for: single residential rooms that's typically covered under simpler code minimums.

If your project needs proper ventilation compliance, send me your building details. If not, no hard feelings good luck with your project.
