Actually that makes very little difference, if he routes the cables
and connects things correctly.

If ICE instructed him to ONLY use a single point connection panel at
ground level, that is very BAD advice unless EVERY cable including
the power line comes into his room in a bundle from that point.
Anyone who has a shack any distance from the common point ground and
who does not have ALL cables (including the power and telco lines and
even heating ducts and plumbing) all arrive in the room in one tight
bundle of equal length conductors needs a second panel at the room
entrance where every neutral lead, conductor, or shield can connect.
As a matter of fact, the SPG panel at the lower level is almost
certainly not as necessary as the one at his shack entrance. The
cables should all route past the service entrance and be grounded
there, before coming to the shack entrance, but they do not need to
enter the dwelling at that point through a panel. The feedlines can
come up to the room outside in a nice bundle if they can't route next
to telco and power cables to the room. He still needs a panel at the
room entrance that connects ALL of the neutral conductors and acts as
a room common point.
You either bond everything together, or disconnect every single thing
and throw the wires outside during any period when you are not
