Hvac Calculation Excel Sheet 2021 Direct

This tab serves as the primary data entry workspace. Users input the physical geometry of each room or thermal zone:

Typically calculated at 250 Btu/h sensible heat and 200 Btu/h latent heat per occupant.

Ensure the outdoor design temperatures you input align with extreme conditions, not just averages. Sizing for the absolute worst-case scenarios in your region guarantees comfort year-round.

If you are ready to improve your HVAC design process, let's look at a few ways to proceed:
