Inujima Art Project Seirensho
Industrial Heritage and Isolated Island Project 1.Industrial heritage and its geography as regenerable resources Inujima is an isolated island in the Seto Inland Sea in Japan.  In the old days, it flourished as a stone production area, and a copper refinery was constructed and started up in 1909, but was shut down after 10 years.  Since then it has been left untouched for 100 years. Remaining there now are the ruins, large areas of primary energy, such as old quarries and refinery plants, which were constructed by using granite undulation. I thought all the existing materials are regenerable resources, such as old architectures to be ruins, geography, open spaces, infrastructure of factories, wastes, and so on.  There are generally 6 different levels of height on the site, and I considered these as landscapes for keeping the necessary potential energy.  I decided to use level 1 to 4 in this project, and planned architectural figures to utilize and activate chimneys and accumulate energy for years and years.??2.Available natural resources and existing wastes In an isolated island utilizing the natural resources such as sun, wind and earth heat, is very valuable and important due to its geographical feature.  In addition, local products and technological know-how are also available resources worth utilizing.  By the same token, I found new value in the way to utilize waste and useless materials.?Almost all Inujima land is granite, so I naturally decided to use its heat capacity effectively.  In picking and analyzing karami bricks and slag, which were abandoned around sea, we found their good heat characteristics. So I regenerated both wasted materials, using karami bricks and slag in the floor and walls as heat storage material and heat-conducting materials. 3.Composition and function of new brought materials The change of landscape and the amount of materials from outside the island should be minimized in consideration of history, culture, geography, climate, and also have good balance between their amount and weatherability. From researching and analyzing, we find 50% of Karami bricks and slags are composed of iron oxide. So I selected iron structure as main structure of architecture buried in the ground, and decided to use no chemical covering materials, and to leave the iron oxide.  We speculated that the roof of the refinery plants were timber constructions, so I adopted timber for the roof and constructions above ground, also because timber has low heat capacity. We covered the roof with glass for weather-resistance and its heat collecting distinction.  "Regenerable existing energy of geography and construction" ,"Available and sustainable natural resources and wastes" and "Materials newly brought in".  I use them as architectural materials, and give them sizes, volumes and details. That means architecture itself will be mounted in natural balance of payments, following natural unremitting regeneration cycle. I think they are the way to make the architecture to have intelligently existed on earth. As a result, new constructions are composed by 4 main spaces, a cooling corridor utilizing earth heat, a sun gallery for collecting heat by sun energy, an energy hall controlled by the chimney effect of sun and the chimney and landscape controlling circulation of vegetation and water. a.Cooling Gallery utilized earth heat?earth gallery I consider the approach and aisle of museum as a gallery for cooling by utilizing earth heat. I adopted base rough iron for finish and structural material which have large heat capacity. Iron plates were waved to oppose earth pressure, and to expand surface area, meaning 2 functions. Cranked aisle idea on planning was adopted to agitate air. Natural light come in through in the north-facing top light, mirrors mounted at the corners bring sun lights by reflecting. When walking up the approach gallery for sky, visitors can feel cooling air and effect of earth heat. b.Heating Gallery utilized sun energy?sun gallery In this gallery, karami bricks are used for floor materials, which can store heat from sunlight. Glass is used for roof materials to collect heat and to make visitors feel liberation energy of solar radiation heat. c.Main hall for accommodating inner environment?energy hall? Energy hall have equable temperature and humidity throughout the year. In there, equable air is made by accommodating open and shut rate of doors of 2 galleries, earth gallery and sun gallery. As for interior finish material, I used cedar, which has small heat capacity, and keep receiving heat minimized from surface of wall. On the other hand, as for the floor materials, I adopted Inujima granite to make visitors feel large heat capacity, and to make an appeal of Inuwejima granite advantage, such as high quality and large size. d.Hall for energy utilized sun and chimney?chimney hall Above ground, air continues natural convection circulating by changing its density following sun light. Chimney hall have a role of engine to circulate air, utilizing the existing chimney and sun energy, And also, there are visually moving art like mobile, visitors can feel the mechanism of natural convection circulating and understand performance of existing construction, chimney. 4.Space for artists Previously architects have providedfor a even and equable light, heat, and humidity for art.  To do this, museums have been built on large hidden machinery rooms providing large amounts of secondary energy.  If we can make places and spaces to continue the intelligence of Earth, I think the creation and art can transmit a purer message from artists.  This architecture, which has a complete natural energy air conditioning system, is a sustainable earth detail that human beings can use for the future.
