HOUSE CONSTRUCTION METHOD OF SUPPRESSING PROPAGATION OF EXTREMELY LOW FREQUENCY ELECTROMAGNETIC WAVES FROM ELECTRICAL WIRING TO HABITABLE SPACE

摘要

PROBLEM TO BE SOLVED: To provide a house in which propagation of extremely low frequency electromagnetic waves from electrical wiring laid within the house to a habitable space is suppressed.SOLUTION: In the case where a residence time of a resident is investigated for each room on the basis of a statistical approach, rooms in which the residence time is less than 1/4 of total residence times for all residents are defined as a short-time living space and other rooms are defined as a long-time living space, regarding a trunk laying route, it is determined whether each portion of the trunk laying route is more proximate to the long-time living space or to the short-time living space, and a trunk line is laid according to a route most proximate to the short-time living space as an entire trunk laying route. Between indoor electrical wiring laid proximately to the long-time living space and a building material forming the long-time living space, a conductive span bond unwoven fabric which is formed from nylon fibers having a digenite bond and of which the surface resistance value is 80 /square to 300 /square is spread and grounded.
