(57) [Problem] To control an electromagnetic environment so that electronic devices and electric devices such as a computer in an IT society function stably and safely. A non-magnetic and electrically insulating reinforced plastic bar is used for a concrete building 9 without using a reinforcing bar. Covering with an electromagnetic wave shield layer 10 or a specific frequency selection shield layer that shields electromagnetic waves by absorption or the like, and connecting a metal part of the building 9 such as a window frame, a door, a handrail, etc., which is exposed outside, to a first grounding system, Equipment, such as equipment and mechanical equipment, is connected to a second grounding system that is independent of the first grounding system, and is used for electrical equipment, wiring, electric circuit materials, and piping equipment in the building 9 of the electric equipment. , The electromagnetic wave shielding layer 1 A zero to specific frequency selection shield layer is provided to form a discharge line using a lightning arrester and a grounding system independent of the building 9. |
