The three main sources of ignition during a wildfire are embers, direct flame contact, and radiant heat. This is why the FPA and others have the three different zones, of particular distances, where they recommend doing particular things. House can survive large quantities of radiant heat:

On the other hand radiant heat often kills people the most (e.g., through heat stroke).
