<P>PROBLEM TO BE SOLVED: To provide a building capable of creating a pleasant space without the use of any artificial energy, by changing colors of reflection light projected on a ceiling, with utilization of changes of altitude of the sun which depends on seasons. <P>SOLUTION: A first reflecting face 8A colored in a cold color and a second reflecting face 8B colored in a warm color are provided at a position near a daylighting port 7 and a position far from the same inside a building, respectively. Angles and positional relations of the first and the second reflecting faces are so set that direct sunlight S is incident to the first reflecting face but not to the second reflecting face in summer times when the altitude of the sun is high, and the direct sunlight is incident to the second reflecting face but not to the first reflecting face in winter times when the altitude of the sun is low. In summer, reflection light A of the cold color by the first reflecting face is to be projected on the ceiling face 9, and in winter, reflecting light B of the warm color by the second reflecting face, to be projected on the ceiling face. <P>COPYRIGHT: (C)2012,JPO&INPIT |
