Step 1 — Direct UA Steady-State (cooling)

U (W/m²·K):

A (m²):

Internal T_site (°C):

External base T_ext (°C):

Baseline Airflow (CFM):

Cells color-coded: red = warmest → blue = coolest.

Paste a wide table with one datetime column and one column per logger.
Example (CSV): datetime,External,Int1,Int2

Duct dia (in):

Airspeed (MPH):

CFM (optional):

Select two windows on Internal Avg (blue): first = Initial, second = Return.

T₀ (°C):

T_a (°C):

T_r (°C):

Duration (h):

Airflow (CFM):

Location (city or "lat,lon"):

Start date:

End date:
