ROOF STRUCTURE PREVENTING THE EARTH FROM WARMING AND REDUCING HEAT ISLAND AND GROUND STRUCTURE

摘要

PURPOSE: To reduce a rate at which solar beam becomes heat on the ground surface and prevent warming and reduce the influence of a heat island. ;CONSTITUTION: A solar beam-reflecting plate 3 against short waves is installed on the roof face of a building 1. A plurality of long rectangular fins made of a light-absorbing material are erected on the surface of solar beam-reflecting plate so as to longitudinally arrange them in the east and west direction to constitute a reflecting plate with a louver structure, in the roof structure. The reflecting plate with a louver structure may be installed on the roof surface of a building. Fins made of light-absorbing materials are erected on the surface of solar-beam reflecting plate so as to longitudinally arrange them in the east and west direction and an optically transmissible material is charged between the fins to constitute the reflecting plate with the louver structure, as a ground structure. This reflecting plate is buried in the ground surface.;COPYRIGHT: (C)1996,JPO
