<p>Lighting by the sunlight is available in every space in a building, even those spaces which have been hardly utilized such as the basement and ground water pit. The sunlight is collected and guided by optical cables to light radiators which are located in intended spaces of a building. The basement has a cistern for water therein to afford a shelter in the case of emergency, while the ground water pit which is also lighted by the conducted sunshine is usable to cultivate fish, plants, and other foodstuffs. The building is annular except for its first floor so that a cylindrical open space is defined thereinside and also lighted by the sunlight, thereby introducing the sunlight even into the radially innermost spaces of the sunlight.</p> |
