Rotational manifold and building incorporating a ratational manifold

A rotational building assembly comprising:

• a fixed support pedestal;
• a building supported on said support pedestal for rotation about a central substantially vertical axis of rotation;
• and
• at least one rotational manifold unit mounted on said pedestal for providing communication between at least one fixed fluid service line and a corresponding service line supported for rotation with said building, said rotational manifold unit having a first inner manifold member and a second outer manifold member, said second manifold member being fixed against substantial rotational movement relative to said pedestal and said first manifold member being rotatable relative to said second member and fixed for movement with said building about an axis coaxial with said vertical axis of rotation,
• said first manifold member having upper and lower sides, seals carried by said first manifold member and sealing said upper and lower sides of
• said first manifold member to said second manifold member so as to define a fluid chamber between said first and second manifold members,
• at least one port in said second manifold member communicating with said chamber and connected to said fixed fluid service line, and
• at least one port in said first manifold member communicating with said chamber and connected to a said corresponding service line of said building.

• a fluid port communicating with said building service line in said first manifold member and communicating with said chamber and
• a fluid port communicating with said fixed fluid service line in said second manifold member and communicating with said fluid chamber whereby to provide communication between said ports and thus said fixed fluid service line and corresponding building service line through said fluid chamber.
