PURPOSE:To easily ensure an installation position for air-conditioning facilities by providing an outside air intake for air conditioning of a structure, in which an electromagnetic wave shielding member is sticked in the inside, in the housetop, and forming a vertical duct in a tunnellike state via the vertical duct led to respective stories. CONSTITUTION:An electromagnetic wave shielded structure 1 is composed by sticking an electromagnetic wave shielding member 5 on the whole inner side from the housetop 2 to an outer wall 4 of a floor slab on the lowermost story, and providing an outside air intake 6 on the housetop and a vertical duct 7. The outside air intake 6 is made horizontal, and the vertical duct 7, led to respective stories 8 and ventilated, is formed in a tunnel state. The electromagnetic wave shielding member 5 is formed by sticking ferrite tile, etc., on an electromagnetic wave shielding material. This prevents infiltration or leak of an electromagnetic wave from the outside air intake 6, enabling easy ensuring of an installation place for air-conditioning facilities. |
