**First Step:**

We determined the compliance rate at each EL:

Family Equipment Class EL1 Panel 8% Centrifugal Unhoused 1% Power Roof Ventilator 22% Axial Housed 7% Centrifugal Housed 8% Inline and Mixed Flow 21% Radial 10%

**Second Step** Because the mix of Equipment Classes in the LCC sample does not match the mix in the US maket, the data was adjusted using the following weights: The results provided by Wade Smith derived using the AMCA sample, are comparable to the results derived from the LCC sample without adjusting to the US market Equipment class mix.

This dataset is similar to what AMCA used, however, some row were removed because they were considered out of scope or data was missing.
